Basics of Structural drafting standards, Symbols and Shop drawings

Structural drafting standards are based on the best practices and on engineering codes set up by The American Institute of Steel Construction (AISC) and The American Standards Institute (ANSI). Structural drawing practices refer to a style or quality of a drawing provided by the individual drafter to the job.  It is characterized by crisp black line work, lettering, consistency, and uniformity. The production of precise detail drawings is an art and real engineering accomplishment.  

The actual concept of a structural framework should be provided on the architect/engineer's design drawings. These drawings are converted into detail drawings to provide necessary instructions for the shop fabrication and assembly installation of the different structural members. Through the shop drawings the CAD draftsman pass on all technical information required for the shop to fabricate the structural components.  

To prepare required drawings with accuracy, the draftsman must have a comprehensive knowledge of the standard engineering specifications, better understanding of the shop fabrication and field erection process, and should have necessary skills for structural drafting. Hence, it is obvious that the structural drafter develop optimum drawing skills.

Drawing Numbers:
All structural drawings must be marked using the standard designation. Usually, drawings are numbered consecutively with a letter "S" (S1, S2, etc.)

Drawing Scales:
The standard unit for structural dimensions is feet. Usually, the scale is marked as feet and inches. Any scale based on an "Architect's Scale" can be utilized for structural drawings.

Titles:
All things on a drawing must have a title such as a plan view, elevation, section, detail, note column, etc. Titles are mentioned bold enough to catch the viewers' eye. To give prominence, the titles are underlined. Single line, a double line, or a combination of thin and thick lines can be used for underlining.  

Dimensioning:
The style of dimensioning in structural drafting is the same style used in common architectural drawings. The dimension line is a continuous, unbroken line with the dimension figure placed above the line. Its obvious that to not place the dimension figure below the dimension line.

Why is the black sea called so?




In ancient times, colours were assigned to the cardinal directions — with black referring to the north. The Black Sea is an inland sea bou nd by Europe, Anatolia and the Caucasus, and is ultimately connected to the Atlantic Ocean via the Mediterranean and Aegean Seas and various straits. It was also called "inhospitable" (dark area, black) before Greek colonization, because it was difficult to navigate, and because its shores were inhabited by savage tribes. The waters of the Black Sea appear darker than the Mediterranean because of its hydrogen sulphide layer that begins about 200 metres below the surface and supports a uniciue microbial population which produces black sediments.




What is astrobiology?




A branch of astronomy that deals with the identification of habitable regions in the universe, the search for extraterrestrial life and effects of outer space environments on living organisms.

It is an education reform movement in which traditional methods teaching are set aside for a self-study approach, involving online technology — through virtual classrooms, downloadable tools and free learning material — as the favoured mode for education People taking to edupunk believe in a do-it-yourself approach and many are driven to this sort of low-cost, even free education, by a troubled economy. While free lectures and online classes may not give one a degree, they can educate effectively.




What is a cloud burst?




A cloud burst is a form of torrential rainfall accompanied by hail and thunder. It is usually observed in high altitude areas and occurs due to the formation of a low pressure area on the top of a mountain. The low pressure zone attracts clouds to the top of the mountain with great force. When they hit the peak, the moisture content is released in the form of rain. The state of Himachal Pradesh witnesses the most number of cloud bursts. Valleys affected by cloud bursts are generally strewn with huge boulders brought down by the rain. Cloud bursts mainly occur in the Himalayas and can cause ramfall of up to 75 mm per hour.




What is the origin of the word —nat'?




In the United Kingdom, Australia and many other parts of the world, the word 'flat' is used to mean an apartment or a house.

The rights afforded to consumers by lemon laws may exceed the warranties expressed in purchase contracts.




Why do men's shirts have buttons on the left side while women's shirts have them on the right?




The rationale dates back to over a century: men's buttons are on the left because men have always tended to dresK rhemseives and most men (and women, for that matter) are right handed.

What is the gene revolution?




The gene revolution is the application of bio-technology in food production. It is of great potential to farmers as it provides them with disease-free planting material and develops crops that resist pests and diseases, reducing use of chemicals that harm the environment and human health. It can provide diagnostic tools and vaccines that help control devastating animal diseases. It can also improve the nutritional quality of staple foods such as rice and create new products for health and industrial uses.

A cogwheel train is a train fitted with one or more cogwheels, which mesh with the toothed rail-rack, running usually between the normal rails. The system, operating on rack and pinion arrangement, is used in regions where trains operate on steep heights within a short span of time. Most cogwheel railways are mountain railways, although a few are transit railways 6r tramways, built to overcome a steep gradient in an urban environment. The first cog railway was Middleton Railway, UK. Now it is a major tourist attraction of Jungfraujoch, Switzerland.




What is green accounting?




The term 'green accounting' hasn't yet been fully defined. Most agree, however, that in order for a business to be able to reduce its carbon footprint, it must first be able to measure it. Then, once the size of the carbon footprint is known, a business must be able to report the data to regulators, taxation officials, carbon credit trading organizations and other relevant parties. Energy-reliant manufacturers and power-generating utilities feel the most pressure to embrace green accounting, but companies in nearly all business sectors can expect to do so at some level within the next few years.




What is a kangaroo court?




A kangaroo court describes sham judicial proceedings which are conducted without giving the rights of defence to the accused by invoking the expediency clause. In this process, prosecution cases are taken up without witnesses and cross-examination. As the trial proceeds by leaps like a kangaroo, it is known as kangaroo court.

Chop shop can also mean a brokerage that sells fraud non-existent equities. It is used colloquially for shops run by butchers or barbers.




Where is 'magnetic' hill in India?




India's magnetic hill is located close to Leh and is alleged to have magnetic properties strong enough to pull cars uphill. Locals and Indo-Tibetan Border Police personnel claim that aircraft passing through the area have to fly at a greater speed to avoid the pull the hill has on the aircraft in order to avoid its radius which could cause the aircraft to jerk. Vehicles allegedly move uphill even with the engines off. There are similar magnetic hills in Mocton in Canada and New Brunswick in the USA.




What is a digital pet?




A digital or virtual pet is an artificial human companion that exists only in hardware. Interaction with the pet may or may not be goal-oriented. If interaction with virtual pets is goal-oriented then the user must keep it alive and even help it to grow by 'feeding', grooming and playing with it. If the interaction is not goal-oriented, the user can focus solely on building a relationship with it. There are digital pet cemeteries where, after the use of the pet, the owner can lay it to rest.




How did the *$' symbol originate?

What is a cosmic microwave?




Just after the birth of the universe, the atmosphere was extremely dense and glowing white hot. Through the ages, the universe has been cooling — a process that is still going on. Light waves from a very distant part of the early universe reached the earth, making it possible to see the glow. However, since the universe is still expanding, the frequency of the waves of visible light changes to microwave frequency This occurs due to the relative motion of either the source or receiver of the waves or both, with respect to each other. These waves, originating in the early stage of the cosmos, are cosmic microwaves.




What is Fat Tuesday?




Fat Tuesday (also known as Mardi Gras and Shrove Tuesday among other names) is the name given to the last day of epiphany or the day before Ash Wednesday, which marks the beginning of Lent? The word Fat (Gras in French) referred to the ritual of eating sugary fat-filled foods before Lent, when rich foods are given up. In some customs, it refers to the entire season of epiphany where practices like wearing masks and costumes, dancing, sports competitions, parades, etc were held before the fasting and religious obligations of Lent. Fat Tuesday is also Mardi Gras, the festival in New Orleans, Louisiana.




Who invented soap bubbles?




The history of soap bubbles is as old as that of soap. But bubbles are no longer simply soap and water. Invented by Taiwanese bubble solution expert Jackie Lin, the top-secret solution contains a polymer that allows bubbles to resist evaporation. The polymer reacts with air to harden three to four seconds after a bubble is blown. With little or no disturbance, the bubbles can last as long as 10 days and can be caught with dry hands without popping.




What is latte art?




It is art in a coffee cup — the pattern is formed when milk and shots of espresso are poured into a cup of coffee. It could get a designer touch, depending on the expertise of the person serving it. This art could take the form of a creamy-looking heart, a flower, leaves, even cartoon faces, anything which can fit into the cup. All the artist needs is the espresso machine and a deft hand. Latte art takes its name from the Italian caffelatte, meaning coffee-milk.




Why is a theatre screen called silver screen?




Since the advent of films in the early 1900s, theatres have been trying to optimize their viewing quality During the 1920s, movie producers began to incorporate silver because of its reflective qualities, which delivered a better image.

Why are the Nazca drawings one of the great mysteries of archaeology?




In the hot deserts of southwest Peru are some immense, mysterious drawings called geoglyphs. Huge geometric patterns, spirals and figures of animals, and thousands of straight lines are immaculately drawn on the desert surface. Known as the Nazca Lines, after the Nazca Indians who lived there in ancient times, the drawings have mystified scientists ever since they were discovered in the 1920s. From the ground level, the drawings seem like a confused mass of lines. Only when viewed from the air, they convey a definite pattern. Scientists feel they could represent an astronomical calendar, or were part of a religious ritual.




Which plant has the biggest seed in the plant kingdom?




The nut of the coco de mer, also called giant fan palm, double coconut, Seychelles nut, or Maldive coconut, is considered to be the biggest nut in the entire plant kingdom. It is the size of a coconuty and weighs around 27 kg. The alm is found only in the islands of Praslin and Curieuse of Seychelles in the Indian Ocean, and its botanical name is Lodoicea Maldivica.

What is cruel accounting?




There are two methods of maintaining accounts of a business enterprise, namely cash method and accrual method. In cash method, revenues/expenses are taken into account only when hard cash has been received/paid. In accrual method of accounting, revenues are recognized the moment goods or services are pr(|Mg




vided. Both revenue and expenses are




recorded, regardless of income or out go in terms of cash. The accrual method provides better matching of income and expenditure than cash method, but is complicated, errorprone and costly No wonder people call it cruel accounting.




What is a scale model?




A scale model is a representation or copy of an object that is larger or smaller in size. Its size is proportionate to the original size of the object that it represents. The proportion is often shown in some ratio eg 1:10, which means one inch of scale model is equivalent to 10 inches of original object. Very often, the scale model is smaller than the original and is used to represent an original object, an imagination or model for an upcoming project. Scale models are built for many cars, buildings, landscapes and huge projects.




What is cybertecture?




It is architecture in another form, the creation of living and working spaces which are a harmonious blend of technology, multimedia, intelligent systems and user interactivity. These spaces can be customized and the residents can claim to be the world's most connected community. Cybertecture even allows a person to select preferred background music. One such cyberstructure is coming up on an area of 32,000 square metres in Mumbai called the Cybertecture Egg. It will have 13 floors of offices, and include a feature to monitor occupants' health, besides virtual scenery which can be changed.




What was Indian mythological figure Rishyashringa or Shringirishi famous for?




Shringirishi, son of rishi Vibhandak and descendant of Lord Brahma, was a noble rishi. He was famous for performing Puttreshthi and Parjanya yagna. He performed Parjanya yagna to the rain god to help King Rompad overcome famine in his kingdom, Ang Desh (Bihar). On an invitation from rishi Vashishtha, he performed the uttreshthi yagna for King Dasharath, and four sons — Rama, Laxman, Bharat, and Shatrughna — were born to him. It is believed Rishyashringa led the way for the Mahanadi river from Sihoba, Chhattisgarh and em- phasized water management. There are 64 temples and ashrams dedicated to him.




How did the term French leave originate?




French leave primarily means taking leave without permission from work. Some believe it is meant to convey the act of leisurely desertion from a military unit. Being away on leave from one's post or duties has its roots in the 17th century and does not so much have its origins in cowardice but in a French custom of leaving a party without saying goodbye or thanking the hosts. The term is still in use in the Indian Navy for sailors who overstay on land.




What is crowdfunding?




The crowdfunding approach has its precedent in charity. It is inspired by crowd sourcing, that describes the collective cooperation, attention and trust by people who network and pool their money together, usually via the internet, to support efforts by other people.

Why do tornadoes usually spin anti-clockwise in the northern hemisphere, and clockwise in the southern hemisphere?




The spin in the two hemispheres is explained by the coriolis effect, which states that the earth, when viewed from the poles, rotates anti-clockwise in the northern, and clockwise in the southern hemisphere. Hence, thunderstorms (which usually travel from the equator to the poles) tend to veer to their left in the northern and right in the southern hemisphere. Tornadoes which occur in a particular area tend to inherit their spin from the direction of the prevailing winds, but this phenomenon is evident in only in large tornadoes.




What is albedo?




Albedo is a term used in reflectivity It is derived from Latin and means 'whiteness'. The albedo of an object is a measure of how strongly it reflects light from sources like the sun. It is given as a number from 0 (dark) to 1 (bright). It is the ratio of total reflected to incident electromagnetic radiation, and is an important expression used in climatology, astronomy, computer graphics and computer vision.




Is smoking hookah better than smoking cigarettes?




It is a myth that smoking a hookah is safer than smoking cigarettes because hookah smoke is filtered through water before it is inhaled. Recent studies have found that hookah smokers actually inhale more nicotine than cigarette smokers because of the massive volume of smoke they inhale. A recent World Health Organization advisory laid that a typical one-hour hookah session exposes the user to 100-200 times the volume of smoke inhaled from a single cigarette. Even after passing through water, the smoke produced contains high levels of toxic corn pounds, including carbon monoxide heavy metals and carcinogens.




What is the Albertopolis?

What is a hermit crab?




The hermit crab is a type of crab that doesn't have a very hard shell. Since its shell is not strong enough, it uses old shells of other animals for protection, especially that of old whelk. This habit of living in a second-hand shell gives rise to the popular name 'hermit' crab. Most hermit crab species live on the ocean floor, though there are many that live on land. Female terrestrial hermit crabs must return to the sea to breed. Hermit crabs are invertebrates, omnivores, and scavengers.




What is a banana problem?




The term comes from the story of the little girl who said, "I know how to spell 'banana', I just don't know when to stop". The banana problem basically means not knowing where or when to stop. It is usually used in computer programming when an algorithm with improper termination commands leads to repetition. It also applies to a web design, which is subjected to feature creep or the rapid expansion of features which complicate the simple design.




What is Operation Smile?




Based in Norfolk, Virginia (USA), Operation Smile is a non-profit medical charity NGO with branches in more than 50 countries, including India, providing remedial surgeries to children with cleft lips and cleft palates. Established in 1982 by Dr William Magee and Kathleen S Magee, Operation Smile organizes international volunteer missions, coordinates training for physicians and helps host countries in treating these medical complications. Operation Smile* has provided free cure to nearly 1,50,000 children and young adults across the world.




Who invented the kite and when?




No one knows exactly how or who invented the first kite. It is thought that the earliest use of kite s was among the Chinese, approximately 2,800 years ago. The kite was said to be the invention of the famous 5th century BC Chinese philosophers Mozi and Lu Ban. By 549 AD, paper kites were being flown — in that year a paper kite was used as a message for a rescue mission. Ancient and mediaeval Chinese sources list other uses of kite for measuring distances, testing the wind, lifting men, signalling, and military communication.




What is the White Revolution?




In India, Gujarat and Rajasthan has excess production as compared to local consumption of milk. In 1970, the National Dairy Development Board initiated activities like building veterinary centres, milk chilling centres, processing plants and strengthened the milk cooperative movement based on Anand Milk Union Limited (AMUL). This was done through Operation Flood, with aid from the Food and Agriculture Organisation in the form of butter oil and milk powder. This ushered in the White Revolution in India, making it the world's largest milk producing country.




What is a nap pod?




A nap pod is a sleep chair designed like a cocoon to allow office-goers a power nap. Companies are opting for nap pods as part of their furniture, as a cat nap is being increasingly believed to refresh a person and increase productivity. The chairs are designed ergonomically to improve blood supply to the back and head; the cocoon-like structure keeps out office noise. There is also an alarm to wake up the sleeper.




What are transparent soaps made of?




Transparent soaps are made of glycerin, and are partly soap and partly solvent. Sodium hydroxide causes crystals to form in soap, which is why the soap becomes opaque. In order to make it transparent, the soap has to be dissolved in enough solvent to make the crystals so small that light passes freely through, making the soap look transparent. There is no magic number when it comes to the quantity of solvent required. A good way to find the right quantity of solvents is to start by calculating a 60:40 soap-solvent ratio and then changing it to a 50:50 soap-solvent ratio.




How does a computer or laptop keep track of time even when it is switched off?




A desktop PC has a lithium cell or battery (the same is used in digital diaries) called a BIOS cell inside the CPU, and attached to the motherboard, which keeps track of time even after the computer is powered down, whereas in laptops, the battery of the laptop itself is used to keep track of time. This battery also saves the settings required during a boot operation.




What is carnival glass?




Carnival glass is pressed glass, meaning that hot molten glass which may or may not contain colour of its own is poured into metal moulds and conforms to their shape. While the glass is still hot, various solutions of metallic salts are sprayed onto the surface and the piece is reheated. The result is a piece of iridescent glassware with a rainbow-hued finish. Many pieces of carnival glass feature a distinctive marigold colour with random swirls of other colours strewn throughout the glass. Carnival glass originated as a glass called Iridill, produced in 1908 by the Fenton Art Glass Company. Iridill was inspired by the fine blown art glass of makers like Tiffany and Steuben, but Fenton sold it cheap. They were used as carnival prizes and thus the name.




What is the origin of the term chutzpah?




The word chutzpah entered the English language in the late 19th century It is supposed to have been derived from khutspe, belonging to the Yiddish language Khuptse means impudence or gall.

It is half a dialogue. For a person lis- tening in on a phone conversation, only half is audible. This audible half is termed halfalogue. Those who listen in — or are forced to simply because they happen to be in the vicinity — on such conversations generally find a halfalogue irritating. But a one-sided conversation usually piques a person's interest into overhearing what is being said.




Who is a soul surfer?




The first published mention of soul surfer was in 1963, in an instrumen-tal 'Soul Surfer' by Southern Californian surf guitarist Johnny For-tune. It was intended to harness the popularity of the 'soul' movement in music, m 1969, theologian Tom Blake's 'Voice of the Wave' examined the re-




ligious elements of surfing. The Soul Surfer expresses himself through his unity with the breaking wave, using his body to translate the essence of the wave's spirit into art with no care for fame.




What is a bonobo?




The bonobo (pan paniscus) is a great ape most closely related to the chimpanzee. It is the least known of the great apes because it lives in a remote rain-forest region of central Africa, and was identified as a species only in 1933. Because of the similar morphological traits (physical appearance) between bonobos and humans, some anthropologists consider the bonobo to be the best living prototype for the common ancestor of humans.




What is the 'Thor's Hammer'?




Mjollnir is the hammer of Thor, a major god associated with thunder in Norse mythology. Distinctively shaped, Mjollnir is depicted as one of the most fearsome weapons, capable of levelling mountains. Thor is associated with strength and the protection of mankind.

How did the handshake originate?




The origin of the handshake is difficult to specifically determine. Herbert Spencer in his book "The Principles of Sociology"* mentions that two Arabs met in a desert, accepting that they wouldn't kiss each other's hand and only clasp it, as kissing was consid ered an insult. A more practical ori gin comes from mediaeval Europe, where kings and knights would extend and grasp each other's hand as a demonstration that they did not pos sess concealed weapons and intended no harm to each other.




From which language is the term 'gymnastics' derived?




The term 'gymnastics' is derived from the Greek word 'gymnos', meaning to exercise naked, a rule that applied in ancient Greece to all exercises practised in the gymnasium by male athletes. It was done so as to increase an appreciation of the male body and as a tribute to the gods. Of the modern events currently considered to be gymnastics, only tumbling and a primitive form of vaulting were known then.




What is email apnea?




Email apnea is the stress caused by the inability to process emails and connect even as mails flood the inbox. It is marked by a suspension of breathing, shallow breathing or hyperventilating while checking mail. Researcher Linda Stone coined this term after realizing that many people go through this process every morning, the mind whirling from mail to mail, filing, forwarding etc. She also found the effect of this kind of apnea on general health to be negative in the long term.




— Sanjay Singh, Bhopal




What is time dilation?




In the theory of special relativity the slowing down of a clock as determined by an observer who is in relative motion with respect to that clock, is called time dilation. In this phenomenon, a person finds a clock (or other time device) similar or identical to their own, ticking at a slower pace, making the observer believe that time has "slowed down" for the other clock but in reality, tune passes at a constant rate. For example, as a spacecraft approaches, to an observer on earth, if he watches the clock on a spacecraft, it will seem that the clock is ticking slower than their own, as a result of relative motion.




What is marketing myopia?




The term was first used by Theodore Levitt, an economist and editor of Harvard Business Review, who is also famous for the term 'globalization'. Management gurus define marketing myopia as a company's short-sighted, ternporary or narrow-minded approach while marketing their product. Companies need to adapt themselves to the changing market. When a firm changes its marketing focus from customer to its product or the company itself, it is also called myopia. A classic example is Hindustan Motors, which failed to change with the economy




How is market size calculated?




Market size refers to the total revenue generated through the sales of a par- ticular good or commodity The most basic methodology is to multiply customer base with its wallet share for a typical customer. For instance, to calculate market size of toothpaste in India, we need to find the product of the number of toothpaste buyers across India with the price of toothpaste. A more accurate estimate can be found by segmenting the customer base as per income or geography, as they dictate the money spent on a particular commodity




What is the anti-sense gene?




The term anti-sense comes from the fact that messenger RNA is synthesized from one of the two strands of the DNA double helix — that strand is called the template, or sense strand. The complementary strand of DNA is called the anti-sense strand. The two DNA strands— sense and anti sense -—are complementary toeach other and form a double helix. The two RNA strands produced from these DNA strands are also complementary When bound into a double helix, the RNA strands cannot function to produce proteins.




How is the date of Buddha's birthday celebration determined?




Traditionally Buddha's birthday is known as Vesak or Visakah Puje Vesak is the major Buddhist festivel of the year as it celebrates the birth enlightenment and death of the Bud dha on the one day, the first full moon day of the sixth month of the Bud




dhist lunar calendar, or the fourth month of the Chinese calendar or in May, (except in a leap year when the festival is held in June). This celebration is called Vesak, the name of the month in the Indian calendar.




What is sunlighting?




A take-off from moonlighting — which means taking up a second job in the evening — sunlighting means taking time off from one's day job to fit in other work and be paid for it. Sunlighting has a slightly adverse meaning: a person takes up a second job, and it begins interfering with the first job. Sometimes, moonlighting stretches into the day, and turns into sunlighting.




What is sweat equity?




The phrase 'sweat equity' refers to equity shares given to the company's employees on favourable terms, in recognition of their work. With sweat equity, employees become part owners and participate in the profits, apart from earning salaries. The Companies Act defines 'sweat equity shares' as shares issued to employees or directors at a discount, for providing knowhow or making available intellectual property rights or value additions.




What is a super galaxy?




A galaxy is a group of large number of stars in the sky which have generally the same origin of evolution, such as our Milky Way. A galaxy may contain billions of stars. A cluster of galaxies, which may have up to 10 or even more galaxies is called a local group. Clusters of galaxies are known as a super galaxy, or a super cluster. This may have up to 50 or even 1,000 galaxies. The Milky Way is a member of the Virgo super cluster.




Who is dubbed patient zero?




Patient zero is the first patient who indicates the outbreak of a disease, and may help indicate its source and possible spread. The term was used by Dr William Darrow to refer to the spread of HIV in North America, which showed how 'patient zero' had infected multiple partners with HIV, and how the virus had spread across the world. Journalist Randy Shilts wrote about patient zero, Gaetan Dugas, a promiscuous flight attendant, based on Darrow's findings.




What is a Jovian planet?




Jovian planets, also known as gas giants, is a collective term for Jupiter, Saturn, Uranus and Neptune. The term Jovian came from planet Jupiter, which describes the other gas giants in our solar system which are like Jupiter. These planets are surrounded by a number of moons and rings and their rotation is faster than terrestrial planets. Jovian planets have a dense core surrounded by a huge layer of gas which is made up of hydrogen and helium.




What is a baker's, dozen and how did the phrase originate?




Baker's dozen means 13, instead of 12. The tale behind its origin is that a mediaeval law specified the weight of bread loaves, and any baker who supplied less to a customer was in for dire punishment. So bakers would include a thirteenth loaf with each dozen just to be safe. It is said that during good harvests, bakers sold one excess loaf to middlemen. A baker's dozen takes on importance in large families, where that little extra goes a long way




What is a vaudeville show?




Vaudeville was a theatrical genre of entertainment in the United States and Canada from the early 1880s to early 1930s. Each performance was a series of separate, unrelated acts grouped together. They included popular and classical musicians, dancers, comedians, magicians, female and male impersonators, acrobats, even scenes from plays and movies. Called "the heart of American show business", vaudeville was very popular.




Who is a downager?




A downager is a person who acts younger than his or her age. There is a growing trend among women aged over 60 to live it up, hence the term dowager has been reinvented as downager. A study of independent, socially active Australian women found them working, studying, starting businesses and changing careers at the age of 60 and above. Downager reflects the "act younger, live younger" attitude of women who were earlier thought of as grandmotherly, retired individuals.




How does calcium carbide ripen mangoes?




For reasons of safe transportation of fruits, mangoes, bananas etc are picked before they ripen fully Slightly green harvested mangoes are subjected to small containers of calcium carbide (CaC2) with a plastic covering. CaC2 reacts with the moisture in the air to release acetylene (or ethyne) gas, which like ethyleneis — a chemical substance produced by fruits to accelerate the normal process of fruit maturation — is a ripening hormone. Industrial-grade calcium carbide contains arsenic and phosphorus, and its use for the purpose of ripening is illegal in many countries.




What is wet wing in aeronautical terms?




A wet wing is an aerospace engineering technique where an aircraft's wing structure is sealed and used as a fuel tank. By eliminating the need for fuel bladders, aircraft can weigh less and offer improved performance. Wet wings are common among civilian designs, from airliners to small general aviation aircraft. Because tanks are an integral part of the structure, they cannot be removed, and require access panels for routine maintenance and visual inspections.




Who, or what, is Attaboy?




Attaboy is an alteration of 'That's the boy!' It Is used to cheer somebody on and to express enthusiastic encouragement or approval to a man or boy. It is an act of congratulating somebody on an achievement. Example: he received several attaboys from the top management after the presentation.




What is gas flaring and why is it done?




In chemical factories, oil refineries, oil wells, rigs and landfills, gaseous waste products and sometimes even non-waste gases produced are routed to an elevated vertical chimney called a gas flare and burnt off at its tip. This is called gas flaring. Waste gases are subjected to such a process either because the gases are waste or it is difficult to store and transport them. Non-waste gases are burnt off to protect the processing equipment when unexpected high pressure develops within them. Gas flaring in oil rigs and wells contribute significantly to greenhouse gases in our atmosphere.




What is Bafana Bafana and how does it get its name?




The word 'Bafana' is a Zulu word, plural for 'umfaan', meaning boy. There is also a movie about Mandela in jail called "Goodbye Bafana". Bafana Bafana is the national football team of South Africa and is controlled by the South African Football Association, which will be hosting the 19th FIFA World Cup in June 2010. Bafana Bafana, meaning Boys Boys, was coined by three Sowetan sports reporters in 1992, shortly after the readmission of South Africa to world football. South African football team members wear blazers with a springbok on the left breast pocket and are also referred to as Springboks.




What is an aggressocracy?




Aggressocracy is a society in which the most aggressive members rise to the top.

Who won the first Paime d'Or at Cannes?




The Palme d'Or (Golden Palm) is the highest prize awarded to the director of the best feature film at the annual Cannes Film Festival. It was introduced in 1955 by the organizing committee, and the first was awarded to director Delbert Martin Mann Jr for his film "Marty". The Palme d'Or was established as the film festival's highest award until 1964, when it temporarily resumed awarding Grand Prix due to copyright problems with the Palm. In 1975, the Paime d'Or was reintroduced and became the symbol of the Cannes Film Festival.




What is biomagnification?




Some compounds are neither recycled by decomposers nor are they released into the atmosphere. Instead, they remain in the ecosystem in virtually unchanged form as they are passed from one organism to another by predation. For example, if a large fish consumes five small ones every day for several years, some of the compounds in their flesh is transferred to the larger fish. Over time, the larger fish accumulates these compounds. An example is the pesticide DDT — its toxic effects may not be apparent in the little fish but accumulation in the larger fish allows the effects to be magnified. Hence, the term biomagnification.




What is apogee?




Apogee is the point in an orbit most distant from the body being orbited. With reference to earth, it is the point in the orbit of a heavenly body, especially the moon, or a man-made satellite, which is farthest or most distant from the centre of the earth. It is also the farthest or highest point — the apex or climax. Perigee is the opposite of apogee and is the point in the orbit which is nearest to the earth.




What is the difference between rights and bonus issue?




Bonus issues are shares issued free of charge to shareholders. When a company accumulates a large fund from profits, much beyond its needs, the directors may decide to distribute a part of it among the shareholders in the form of bonus. Once a bonus is issued, the price of the shares is likely to drop as the value of the company's assets is now spread over larger number of shares. Right shares are issued to existing shareholders who have the privilege to buy a specified number of new shares from the firm at a specified price within a specified time. A company can opt for a rights issue to raise capital under secondary market offering.




What is the Yellow Revolution?




The growth, development and adoption of new varieties of oilseeds and complementary technologies nearly doubled oilseeds production from 12.6 mt in 1987-88 to 24.4 mt in 1996-97, catalyzed by the Technology Mission on Oilseeds, brought about the Yellow Revolution.The term also stands for the People Power Revolution in Phillipines in 1986 against then President Ferdinand Marcos. It was a series non-violent protests where demonstrators used yellow ribbons during the arrival of Ninoy Aquino.




What is rumourtrage?




Rumourtrage is the practice of spreading false news about a company, leading to a drop in its stock price, and followed by increased trade in its shares. This is usually done before a takeover bid. Rumourtrage is common in the corporate world and authorities have found it tough to stamp out the practice as it hinges on hearsay. It is especially used by traders when the market is volatile.




Why do people sweat when theyare frightened?




Fight or flight are two universal responses to any stressful or life-threatening situation in every animal, including humans. In case of severe stress, the sympathetic nervous system is stimulated, which is meant for tackling such situations. It causes the release of adrenaline or epinephrine from the adrenal gland and nerve endings, this results in manifestations of symptoms of fright like sweating, increased heart rate, nervousness, pupil dilation, goose bumps, increased muscular and mental activity and blood supply to the brain and muscles.




What is the Kuiper Belt?




The Kuiper belt is a region of the solar system beyond the planets, extending from the orbit of Neptune. It is similar to the asteroid belt, although it is far larger — 20 times as wide and 200 times as massive. Like the asteroid belt, it consists mainly small bodies or remnants from the solar systern's formation. The Kuiper belt objects are composed largely of frozen volatiles (termed 'ices'), such as methane, ammonia and water. It is home to at least three dwarf planets — Pluto, Haumea and Makemake. Pluto, discovered in 1930, is considered its largest member.




Which was the first major language of Europe?




Most historians agree that Semitic was the mother of all European languages, including a few Asiatic languages. But Semitic had its birth in Asia (Syria and Palestine), so it cannot be called the first indigenous language in Europe. The first recorded indigenous language in Europe was an evolved form of ancient Phoenician, which later travelled north and west to the budding civilization in Greece where this language (crude with just around 22 characters) was developed by the addition of vowels. Thus, ancient Greek was the first major language of Europe.




Who invented the helmet and what is it made of?




The oldest known use of helmets was by Assyrian soldiers in 900 BC. They wore thick leather or bronze helmets to protect the head from blunt objects, sword blows and arrows in combat. Soldiers still wear helmets, now often made of lightweight plastic material, to protect the head from bullets and shell fragments. Today's armed services use high-quality helmets made of ballistic materials such as Kevlar, which have excellent bullet and fragment stopping power.




What is a coco taxi?




Coco taxis are the Cuban equivalent of a rickshaw — a three-wheeled, fibre glass egg-shaped vehicle with two seats glued to a moped. They are called so because they are almost like spherical giant coconuts. Their plastic and fibre glass body, which looks round from the back and sides, forms a protective canopy around the passengers. They tend to flock around busy tourist areas in Cuban cities. Coco taxis, powered by a 75cc two-stroke petrol engine are noisy and more affordable than a regular taxi.




What are time dollars?




Time dollars are the credit a person earns hourly in a Time Bank, set up to facilitate people in a community. A member of a Time Bank earns it by doing something for someone in the community, like baby-sitting or running an errand. After the time dollars are credited in the member's account, he can spend it on whatever he needs. It is a sort of barter system which is serving to bond communities and has turned into a social change movement in 22 countries.




What is the origin of the term Bluetooth?




Bluetooth is the anglicized form of the Danish word Bletand — Ble meaning blue — the victory title given to the 10th century King Harald Gormsson. Harald was born in circa 935 and ruled as King of Denmark around 958 and as King of Norway around 970. Bluetooth technology was invented in 1994 by Swedish company Ericsson, which found it appropriate to name it after the Scandinavian king who had united several Danish tribes and parts of Norway into a single kingdom. The implication is that a Bluetooth does the work of uniting different communication protocols into one universal standard.




What is the Lady Macbeth Effect?




Lady Macbeth, a character from Shakespear's play "Macbeth", had plotted to kill the king and would repeatedly wash her imaginary bloodstained hands, hoping it would wash away her sins. The Lady Macbeth Effect describes a psychological condition in which people who have done something wrong feel a need to wash their hands or body in order to clear their conscience. They tend to think that physical cleanliness can be a substitute for moral purity.




What is a barcode?




A barcode is an optical machine-readable representation of data on certain products. It can be read by optical scanners called barcode readers or scanned from an image by special software. It is the small image of lines (bars) and spaces affixed to retail store items, identification cards and postal mail to identify a particular product number, person or location. The code uses this sequence to represent numbers and other symbols. A barcode symbol typically consists of five parts: a quiet zone, a start character, data characters (including an optional checkcharacter), a stop character, and another quiet zone. There is no standard barcode.




What is brand interest?




Establishing a brand in the market is the true art of marketing. It's not the product being consumed, but rather the image one has of it. Building a brand is not simply giving a product a name, but also creating an experience. This means keeping in mind the contact people have with the brand. A brand is a name, but when it is powerful, it makes a person think of much more: this is brand interest.




What does breaking bread mean?




Breaking of bread refers to the rite of Holy Communion by Christians. In the Gospel of St Mathew, 26:26, it is mentioned: While they were at supper, Jesus took bread, said the blessing, broke it, gave it to his disciples and said: 'Take this and eat it, this is my body'. In other places also in the Bible, wherever the breakingof bread is mentioned, it refers to the celebration of the Holy Communion by Christ himself, or by the early Christians.

Types Of Engineering Drawing

[simpleaffiliate source="chitika" results="0"][/simpleaffiliate]
types of engineering drawing
What kind of layout is 'aircraft/master layout'? Is 'full size' the actual size!?

In an article explaining layout drawings of engineering drawing, it is said as the following:
' Another type is the aircraft, or master, layout, which is drawn on glass cloth or on steel or aluminum sheets. the object is drawn to full size with extreme accuracy. The completed drawing is photographed with great precision, and a glass negative made. From this negative, photo templates are made on photo-sensitized metal in various sizes and for different purposes, thereby eliminating the need for many conventional detail drawings.'


Yes it shows the part in actual size typically without dimensions. Sounds like a flat pattern drawing used to make brackets and angles from sheet metal. If I recall correctly, these drawings are called Photo Contact Master (PCM) drawings. The drawing shows the detail part in actual size without dimensions. I've seen this type of drawing on mylar sheets. A photographic process is used to duplicate these types of drawings. This ensures accuracy of the drawing as opposed to photocopied paper which can lose its dimensional accuracy from one copy to the next. The technician can either use a scale to measure the dimensions or as in your example, the part outline could actually be "photographed" on the raw material showing where to cut and bend the sheet metal parts.

Professional, Reliable and Cost Efficient Range of Architectural CAD Drafting Services

Computer-Aided Design (CAD) is the use of computer technology to aid in the design and particularly the drafting like technical drawing and engineering drawing of a part or product, including entire buildings. It is both a visual or drawing and symbol-based method of communication whose conventions are particular to a specific technical field.

Drafting can be done in two dimensions (2D) and three dimensions (3D).

Drafting is the communication of technical or engineering drawings and is the industrial arts sub-discipline that underlies all involved technical endeavors.

CAD is mainly used for detailed engineering of 3D models and/or 2D drawings of physical components, but it is also used throughout the engineering process from conceptual design and layout of products, through strength and dynamic analysis of assemblies to definition of manufacturing methods of components.

It includes PDF to CAD conversion also. CAD Conversion can be done from any format such as hand-drawn documents, tiff files, PDF, Scan Docs or other image files to a .dwg file using AutoCAD.

CAD has become an especially important technology within the scope of computer-aided technologies, with benefits such as lower product development costs and a greatly shortened design cycle. CAD enables designers to layout and develops work on screen, print it out and save it for future editing, saving time on their drawings.

You may want to look that your competition to see what keyword density they are using. Too high of a keyword density will be considered search engine spam and can get you blacklisted. A good measure of keyword density is between 3 and 7 percent. Your keywords should be toward the top of your page and your keyword phrase can be in either every paragraph or every second paragraph depending on your paragraph length.


4. Bad Techniques:


Bad search engine optimization techniques can get you blacklisted from a search engine. Some techniques that are considered spam are cloaking, invisible text, tiny text, identical pages, doorway pages, refresh tags, link farms, filling comment tags with keyword phrases only, keyword phrases in the author tag, keyword density to high, mirror pages and mirror sites.


5. Title & Meta Description Tag:


Construction of your title tag is one of the most important things you need to do. Each page should have a different title with 2 or 3 of your keyword phrases at the beginning. When search engine results are displayed the title is the first thing people see. Below the title is a description which will be either be taken from your meta name description content="Description phrase" or from the first sentence on that page. Your description should also have 2 or 3 of your keyword phrases at the beginning as should your first sentence. You should have a different title, description and first sentence on each page. You many also what to try shorter titles with only one keyword or keyword phrase as this will raise you keyword relevance.


6. Meta Keywords Tag:


The meta keywords tag is not as relevant as it used to be and some say Google doesn't ever look at it anymore, but put it in anyway.


7. Author & Robots Tags:


The Author Tag should contain the name of the company that owns the site. This tag will help you get a #1 position for your company's name.


Use a generic Robots Tag on all pages that you want indexed. This instructs the robots to crawl the page. The following is the generic robots tag.


8. Quality Content:


Quality content will bring people back and as people always want to tell others about a good thing it will get you forward links from other sites. Your content should be written with your keyword phrases in mind


9. Quantity Content:


The more the better. Just remember your content will need to be both quantity and quality.


10. Changing Content:


You can do this by hand or with a script. For example you can have a php script that draws five paragraphs from a pool of twenty paragraphs when the content is different each time the php page is accessed. By creating dynamic pages with a script randomly drawing different content from a database, you can get several different home pages indexed by Google and optimize for several different keyword phrases.


11. Avoid Dynamic URLs:


Are your pages served via php, asp, or cf? Some search engines may have a problem indexing them. Try to create static pages whenever possible. Avoid symbols in your URLs like the "?" that you will often find in php, asp or cf pages.


12. Frames:


Many search engines can't follow frame links. Make sure you provide an alternative method for the search engines to enter and index your site.


13. Site Map:


A good menu system is really a site map. A well constructed menu system that is on each page and contains a link to every page on the website is all you need.


14. Site Themes:


All of the top 3 search engines look for site themes or a common topic when they crawl a website. If your site is about one specific topic you will rank better than if you have more than one theme or topic on your site. By using similar keyword phrases in each page the search engines will detect a theme this will be to your advantage.


15. Site Design:


You may think, “what does site design have to do with organic search engine optimization”? Well if your website has a bad color scheme that is hard to read, is not organized, is a cheesy looking site, then all of your site optimization has been a waste of time. Make your site attractive to the viewer, make things easy to find, have you graphic header and menu bar the same place on each page. These things will keep your visitors on the site and bring them back. A well optimized site with a high search engine results position that is ugly and is hard find information on, will not keep the visitors your optimization has brought to the site. Use W3C Link Checker to make sure all your page links are good. If you have broken links on your site this can effect the ranking you are given. Put a proper doctype on each page. If you don't have a proper doctype on each page Internet Explorer will go into quirks mode and display it different. Use The W3C Markup Validate Service to verify that your pages are Validate HTML or XHTML code. The W3C validation will verify that your HTML or XHTML is not broken. This validation shows you any broken code that could keep your webpages from displaying properly in all the different browsers and browser versions.


16. Separate Content & Presentation:


Put all your presentation code into Cascading Styles Sheets (CSS). This separates the presentation from the content and makes your html files up to 50% smaller. It is reported that the search engine bots prefer this and the more content you have compared to presentation in your file, the better you get rated. Read why tables for markup are stupid for an overview.


17. Robots.txt File:


While this file is not really required it should be included so that the search engine bots don't get 404 errors when they look for it. Just include the following 2 lines and drop it in the root.

Risk Anaysis Case Study

Foreword

I wish to acknowledge the support of Mr John Tookey University of Auckland for his generously support and valuable advises.






1. Introduction


Risk management is one of the most critical project management practices, to ensure a project be successfully completed Risk management is thus in direct relation to the successful project completion. Project management literature describes a detailed and widely accepted risk management process, which constructed from four iterative phases known as risk management plan

• Risk identification

• Risk estimation

• Risk response

• Planning and execution


Risk Identification

In this stage , we identify and name the risks , there are different sorts of risks and we need to decide on a project by project basis what to do with each type.


Risk Quantification

Risk need to be quantified in two dimensions. The impact of the risk needs to be assessed. The probability of the risk occurring needs to be assessed. For simplicity, rate each on a 1 to 4 scale. The larger the number, the larger the impact or probability. By using a matrix, a priority can be established.


Fig 1 quantification scale matrix (Ref. 11)


Risk Response

There are four things you can do about a risk. The strategies are:

• Avoid the risk. Do something to remove it. Use another supplier for example.

• Deflect the risk. Make someone else responsible. Perhaps contracting out or insurance against (damage , liability, personnel liability etc


• Mitigate the risk. Take actions to lessen the impact or chance of the risk occurring. If the risk relates to availability of resources, draw up an agreement and get sign-off for the resource to be available.

• Accept the risk. The risk might be so small the effort to do anything is not worthwhile or a contingency plan may be developed to deal with possible effects.


Risk Control

The final step is to continually monitor risks to identify any change in the status, or if they turn into an issue. It is best to hold regular risk reviews to identify actions outstanding, risk probability and impact, remove risks that have passed, and identify new risks.


1.1 Risk management and construction

The construction industry is subjected to more risk and uncertainty than many other industries. The process of taking a project from initial investment appraisal to completion and into use is complex, generally bespoke, and entails time-consuming design and production processes. It requires a multitude of people with different skills and interests and the co-ordination of a wide range of disparate, yet interrelated, activities. Such complexity is further compounded by many uncontrollable external factors (Flanagan and Norman, 1983). The construction industry has a poor reputation in coping with risks, many projects failing to meet deadlines and cost targets. Clients, contractors, the public and others have suffered as a result (Edwards 1995). This study will focus on applying project risk management strategies on construction of Sydney opera house which is a well-known case for cost overrun.

1.2 The aim of the study

The aim of this study is not to reduce the great achievement of construction such a complicated building that changed the face of the city but looking form management point of view to

 Identify and quantify the project risks that been overlooked.

 Highlight the dangers associated with using poor estimate.


1.3 About the Sydney Opera House

 The owner :State government of New South Wales

 Architect :Jorn Utzon

 Engineer: Ove Arup & Parteners

 Cost: $102 million

The Sydney Opera House is the busiest performing arts centre in the world. Since its opening in 1973, it has brought countless hours of entertainment to millions of people and has continued to attract the best in world class talent year after year.


1.4 About the Building

There are nearly 1000 rooms in the Opera House including the five main auditoria. There is also a Reception Hall, five rehearsal studios, four restaurants, six theatre bars, extensive foyer and lounge areas, sixty dressing rooms and suites, library, an artists' lounge and canteen known as the "Green Room", administrative offices and extensive plant and machinery areas. The building covers about 1.8 hectares (4.5 acres) of its 2.2 hectare (5.5 acre) site. It has about 4.5 hectares (11 acres) of usable floor space. It is approximately 185 m (611 ft) long and 120m (380 ft) wide at its widest point. The highest roof vault (above the Concert Hall) is 67m (221 ft) above sea level.

The roofs are made up of 2,194 pre-cast concrete sections. These sections weigh up to 15.5 tones (15 tons) each. They are held together by 350 km (217 miles) of tensioned steel cable. The roofs weigh 27,230 tones and are covered with exactly 1,056,056 Swedish ceramic tiles arranged in 4,253 pre-cast lids.

The entire building weighs 161,000 tones. It is supported on 580 concrete piers sunk up to 25 m (82 ft) below sea level. The roofs are supported on 32 concrete columns up to 2.5 m (8 ft) square. The exterior and interior walls, stairs and floors are faced with pink aggregate granite which was quarried at Tarana in New South Wales. The two woods used extensively to decorate the interiors are brush box and white birch plywood which were both cut in northern NSW. There are 6,225 sq m (67,000 sq ft) of glass, made in France, in the mouths of the roofs and other areas of the building. It is in two layers - one plain and the other demi-topaz tinted. About 2,000 panes in 700 sizes were installed.

There are 645 km (400 miles) of electrical cable. 120 distribution boards regulate the power supply, equivalent to the needs of a town of 25,000 people. Twenty-six air-conditioning plant rooms move more than 28,500 cubic meters (1,000,000 cubic feet) of air per minute through 19.5 km (12 miles) of ducting.

1.5 Design Stage

The original concept for the project was a sketch submitted by Danish architect , Jorn Utzon .Judges selected it from an international open competition that ended with 233 entries from 11 countries. Thought happy to win the competition Utzon was mildly shocked .although his concept had caught the attention of the judges, it consisted only if simple sketches with no plans or even perspective drawings , because the design was so unique , some people presumed it would also be inexpensive to build. No one knew how it would be build , and some experts questioned that it could be built at all.


In spite all uncertainty , the initial project cost estimate was pit at $7million.The government would use profits from a series of state run lotteries to pay the project.

The government was worried that the people scrutinizing the design might raise question about the potential problems hat would stall the project they thus quickly mover ahead and divided the work into three main contracts :the foundation and the building except the roof, the roof, and the interior and equipment.

1.6 Construction stage

Many of the world’s best-known construction companies were involved in building

Sydney Opera House including Arups Structural Engineering, Hornibrook and Rider Hunt, the construction work of S.O.H was divided into three distinct stages as follows (Ref. 19)

• Stage I

Sub structure , concrete structure from the foundation up to the auditoria seating levels excluding any finishes.

• Stage II

Superstructure or shells , concrete roof vaults or major and minor halls an restaurants , including the claddings.

• Stage III

Everything not included in stages I and II , stage towers, all interior finishes, exterior paving and cladding, glass walls , all electrical and mechanical services.


After he was elected premier of New South Wales in 1965, Askin attempted to force Utzon reduce costs by withholding payments. In 1966 Utzon resigned and returned to his native Denmark. He never even returned to see his masterpiece completed.

The construction of the Sydney Opera House was now handed over to a group or Australian architects. Fortunately, the exterior had already been completed by then so that the impact of the altered design on the overall structure was minimal. The project was finally completed in 1973 after a construction period of 14 years and an expenditure of over $A100 million, almost 15 times the estimated budget.

2. Risk management strategies at S.O.H

2.1 Financial

Despite of all cost escalation , taxpayer had little to pay .Virtually all the costs were covered by the proceeds of State Lotteries. The continued need to the subside the running costs of the opera house were financed by the continuation of the Lottery State. The first estimate for the Sydney Opera House was $7.2 million in Australian dollars. Once started, however, costs kept rising and just to complete the building cost $102 million.

2.2 Political

Political risks are often occur in government project as they often hide information affecting the community's support, which in turn affect the effectiveness of the feasibility study . S.O.H we mostly severely effect by political decisions

2.2.1 Media and public deception

In S.O.H. the original budget of seven million Australian dollars was not a real but a political budget .The labour government of New South Wales the main proponent of the S.O.H, wanted the project started before elections in March 1959-this would reduce the risk of the stopping the project in case Labour lost the elections (8).


2.2.2 Deceptive cost estimate

Kim Utzon explains in lieu of his father "It was a political decision to publicize a low budget for the building, which was expected to gain approval in the political system, but which very quickly was exceeded. So even if the cost overrun turned to be 1400% in relation to the publicized budget, this budget was an eight of the real budget of the building .So the real overrun is only 100% the rest was politics".


2.2.3 Political construction date

The start of construction for stage I was fixed ., largely for political reasons , as the 2nd March 1959.Thus Proceeding with construction before completing the design process which is a great risk .

2.2.4 Political design changes

On 1966 major hall was changed from dual purpose for concert and opera to a single purpose concert hall, the dual purpose was a requirement of the competition .


2.3 Structural

2.3.1 The Supporting points

Arup and his engineers knew very well that the cross-section shape Utzon chose was far from ideal known structures, however they could not suggest changing to the shape as it will alter the appearance of the roof drastically.

2.3.2 The roof

A question should be asked if this design is achievable?. The competition judges choose a complex art design without asking how it will be deigned? later on it was a major cause for delaying the roof design if this point was been considered they should either choose a simple shape or a known geometry, at this stage computer program analysis was not yet been introduced that means only manual process can be used to calculate the forces acting on the structure.

2.3.3 Lack of suitable boundary condition.

Another technical problem that the engineer had to solve was the lack of boundary condition that leads to some earthwork as sub base for the structure foundation.

2.4 Technical

Utzon, ware of possible technical problems since his design required advanced technology not yet available, requested additional time to tackle those challenges Utzon faced the task of converting the concept into a design form which a structure could be built, but he had no prior experience in the design and construction of such a large building. Because of this lack of plans, detailed design drawings, and estimates of materials, little existed from which cost could be determined.

2.4.1 Design errors and omissions

• Unfortunately, the roof shells were too heavy for the supporting columns that were already built, so these were demolished and rebuilt. These and several other setbacks led to delays and increasing cost overruns.

• The original design called for two theatres. The government changed its mind and required the building to be altered and that four theatres now be incorporated into the design

• The foundation been demolished to suit the new roof design loads.

2.4.2 Fitness for purpose.

 The main design overlooked acoustic requirements which is the main purpose of the building and had to be altered at later stage.

 The Running costs for S.O.H proved expensive , it was a very labour intensive building .In 1974 , it operation cost was $A6M, of which only $A2M was covered by the revenue. Thus costs ruled out small scale opera and the Australian Opera were forced to seek a cheaper venue.

2.5 Construction

Engineers who revised the concept noted that the roof shells were much larger and wider than any shells seen so far. Further, because they stuck up so height, they would act like sails in strong winds blowing up the harbour. Thus, the roof would have to be carefully designed and constructed to resist such wind pressure.

The construction was estimated to take about five years at a cost of A$7 million. Ignoring his request, the government pressured Utzon into starting construction in 1959, two years ahead of the architect's proposed schedule.

 The lack of preparation soon backfired. After the completion of the grand podium with an enormous, 86 meter (282ft) wide stair, several years were spent reworking the design of the roof.

• Three tower cranes imported from France for this job costing $100,000 each and it was the first building constructed in Australia using tower cranes.

• Unfortunately the roof shells were too heavy for the supporting columns that were already built, so these were demolished and rebuilt.


2.6 What goes wrong Consequences?

 Coast overrun 1300% (Ref. 18)

As feared many experts the project become an engineering financial debacle, lasting 15 years and costing $107 million ($100 million over the initial estimate).

 Schedule overrun 250% (Ref. 18)

 Media and public scandal



Fig 5 Time /cost Escalation


 Management conflict occur between the client and the architect that cause him to resign before the end of stage III .


3. Risk identification quantification

3.1 Identification

By looking at the project there are some risks appear not used have the most adverse effect on the project

1. Poor Cost Estimate.

2. Incomplete design.

3. Failure to keep within the cost estimate

4. Failure to achieve the required completion date.

5. Changes in project scope and requirements.

6. Design changes.

7. Pressure to deliver project on an accelerated schedule.

8. Inaccurate contract time estimate

9. Lack of communication between project participants.

10. Inadequately defined roles and responsibilities.

11. Insufficient skilled staff.

12. Political risks.

3.2 Qualitative risk analysis

Qualitative risk analysis assesses the importance of the identified risks and develops the prioritized lists ,using the 1 to 4 scale matrix discussed above to quantify identified risks


Risk Probability Impact Risk Importance

1. Poor Cost Estimate. 3 3 Critical

2. Incomplete design. 1 3 High

3. Failure to keep within the cost estimate 3 4 Critical

4. Failure to achieve the required completion date. 4 3 Critical

5. Changes in project scope and requirements. 1 3 High

6. Design changes. 2 2 Low

7. Pressure to deliver project on an accelerated schedule. 2 2 Low

8. Inaccurate contract time estimate 3 4 Critical

9. Lack of communication between project participants. 3 4 Critical

10. Inadequately defined roles and responsibilities. 1 4 High

11. Insufficient skilled staff. 1 2 Low

12. Political risks. 4 2 Medium

Three risks were selected for detailed qualitative risk assessment (refer to sheet 1 , 2 and 3)





Risk Risk Control

1. Poor Cost Estimate. Client, Contractor

2. Incomplete design. Client , Contractor

3. Failure to keep within the cost estimate Client

4. Failure to achieve the required completion date. Client, Contractor

5. Changes in project scope and requirements. Engineers

6. Design changes. Contractor

7. Pressure to deliver project on an accelerated schedule. Engineers

8. Inaccurate contract time estimate Contractor, Client

9. Lack of communication between project participants. Engineers, Contractor, Client

10. Inadequately defined roles and responsibilities. Engineers, Client

11. Insufficient skilled staff. Client

12. Political risks. Contractor



3.2 Risk response

3.2.1 Risk Avoidance

As discussed most of the risk could be avoided by only

• Completed design .

• Estimating at a very detailed level.

• Not selecting untested design .

• Using local Architecture office will reduce many and more communication and experienced architecture designer

3.2.2 Risk transfer

• Using a fixed price contract will transfer construction risk to the contactor.

• Obtaining Insurance to cover costly risks.

3.2.3 Mitigate the risk

Risk analysis shows that no clear management process for controlling the project however using an experienced project manager would effectively reduce probability or impact of risks to an acceptable level.

4. Assessment forms

5. Lessons learned

• Risk must be identified to be managed

• A poorly defined risk structure will breed more risks.

• A proper risk management strategy would planning.

• All designs and calculations should be checked before they leave the design office further check calculation should be made by the authority , many errors that escape are picked up and corrected during construction .This often cause a delay to the project and might effect the cost.

• The goal is to prevent political and business interests from interfering with design and thus to arrive at an outcome as close as possible to the original design drawings.

• Continually monitor risks to identify any change in the status, or if they turn into an issue. It is best to hold regular risk reviews to identify actions outstanding, risk probability and impact, remove risks that have passed, and identify new risks.

• Risk management is not one off activity instead, it should be applied continuously through the project life.

• The best way to control budget is not to proceed with the building unlit you have all the drawings complete.

6. Conclusion

Study clearly identify the great importance of risk management on construction projects, negligence will lead to an expensive cost effecting the project successes.

A risk analysis project shows a large number qualitatively ranked as 1 , those risks have a high probability of occurrence and height consequence shared between the client 42% , the contractor 36% and the engineer 21% .

This indicates that it was a very risky project nevertheless risks were either downplayed or ignored , and not much was done to keep them under control, the project management strategies was only focused on keeping the project going no matter how it is going .

Finally although the opera house put Sydney on the world map, both architecturally and culturally but from project management perspective it was a spectacular failure as a consequence of ignoring risk management.
