Science Reflection Paper Essay Example
Science Reflection Paper Essay Reflection paper Sci-114 In this reflection paper I will address the elements of the course that I found most challenging, the areas which informed my understanding of an aspect of Earth science with what I already knew and list the areas I would have liked to have explored more in depth. In addition to this reflection paper I will address the concerns of global warming as well. The most challenging part of the course by far was the virtual lab work. My problems with the virtual labs were that to solve a problem from the paper wasnââ¬â¢t very assessable all the time. Some of the questions were a little tricky and navigating through the browser wasnââ¬â¢t always simple. I did however appreciate the assignment instruction sheets you printed off weekly to help further explain what exactly we needed to do in depth. A topic area of the class that I was already familiar with, but was informed with more in details was the topic of sever weather. Iââ¬â¢ve never really understood air masses, lake-effect snow, fonts/formations cyclones before. Having to research and do presentations on server weather broaden my knowledge and understanding on this area which will be beneficial moving forward. The area in this course in which I would have liked to have explored more on would have to be plate tectonics and the natural catastrophes caused by them. I did get the basic general understanding of plate tectonics, but could have used just a bit more insight on them to familiarize myself a little more.

Global warming shows no sign of cooling down and will continue to cause problems here on earth as itââ¬â¢s already have. Average temperatures have already climbed 1. 4 degrees since 1980 and are climbing. The artic areas are feeling the effects the most with temperatures that have risen nearly twice the global warming average. Global warming will bring more server weather such as wildfires, heat waves and tropical storms if we continue to ignore this serious issue.

A Brief Overview of British Literary Periods
A Brief Overview of British Literary Periods Although historians have delineated the eras of British literature in different ways over time, common divisions are outlined below.à Old English (Anglo-Saxon) Period (450ââ¬â1066) The term Anglo-Saxon comes from two Germanic tribes, the Angles and the Saxons. This period of literature dates back to their invasion (along with the Jutes) of Celtic England circa 450. The era ends in 1066, when Norman France, under William, conquered England. Much of the first half of this period, prior to the seventh century, at least, had oral literature. A lot of the prose during this time was a translation of something else or legal, medical, or religious in nature; however, some works, such as Beowulf,à and those by period poets Caedmon and Cynewulf, are important. Middle English Period (1066ââ¬â1500) The Middle English period sees a huge transition in the language, culture, and lifestyle of England and results in what we can recognize today as a form of ââ¬Å"modernâ⬠(recognizable) English. The era extends to around 1500. As with the Old English period, much of the Middle English writings were religious in nature; however, from about 1350 onward, secular literature began to rise. This period is home to the likes of Chaucer, Thomas Malory, and Robert Henryson. Notable works include Piers Plowman and Sir Gawain and the Green Knight.à The Renaissance (1500ââ¬â1660) Recently, critics and literary historians have begun to call this the ââ¬Å"Early Modernâ⬠period, but here we retain the historically familiar term ââ¬Å"Renaissance.â⬠This period is often subdivided into four parts, including the Elizabethan Age (1558ââ¬â1603), the Jacobean Age (1603ââ¬â1625), the Caroline Age (1625ââ¬â1649), and the Commonwealth Period (1649ââ¬â1660).à The Elizabethan Age was the golden age of English drama. Some of its noteworthy figures include Christopher Marlowe, Francis Bacon, Edmund Spenser, Sir Walter Raleigh, and, of course, William Shakespeare.à The Jacobean Age is named for the reign of James I. It includes the works of John Donne, Shakespeare, Michael Drayton, John Webster, Elizabeth Cary, Ben Jonson, and Lady Mary Wroth. The King James translation of the Bible also appeared during the Jacobean Age.à The Caroline Age covers the reign of Charles I (ââ¬Å"Carolusâ⬠). John Milton, Robert Burton, and George Herbert are some of the notable figures. Finally, the Commonwealth Age was so named for the period between the end of the English Civil War and the restoration of the Stuart monarchy. This is the time when Oliver Cromwell, a Puritan, led Parliament, who ruled the nation. At this time, public theaters were closed (for nearly two decades) to prevent public assembly and to combat moral and religious transgressions. John Milton and Thomas Hobbesââ¬â¢ political writings appeared and, while drama suffered, prose writers such as Thomas Fuller, Abraham Cowley, and Andrew Marvell published prolifically. The Neoclassical Period (1600ââ¬â1785) The Neoclassical period is also subdivided into ages, including The Restoration (1660ââ¬â1700), The Augustan Age (1700ââ¬â1745), and The Age of Sensibility (1745ââ¬â1785). The Restoration period sees some response to the puritanical age, especially in the theater. Restoration comedies (comedies of manner) developed during this time under the talent of playwrights such as William Congreve and John Dryden. Satire, too, became quite popular, as evidenced by the success of Samuel Butler. Other notable writers of the age include Aphra Behn, John Bunyan, and John Locke. The Augustan Age was the time of Alexander Pope and Jonathan Swift, who imitated those first Augustans and even drew parallels between themselves and the first set. Lady Mary Wortley Montagu, a poet, was prolific at this time and noted for challenging stereotypically female roles. Daniel Defoe was also popular.à The Age of Sensibilityà (sometimes referred to as the Age of Johnson) was the time of Edmund Burke, Edward Gibbon, Hester Lynch Thrale, James Boswell, and, of course, Samuel Johnson. Ideas such as neoclassicism, a critical and literary mode, and the Enlightenment, a particular worldview shared by many intellectuals, were championed during this age. Novelists to explore include Henry Fielding, Samuel Richardson, Tobias Smollett, and Laurence Sterne, as well as the poets William Cowper and Thomas Percy. The Romantic Period (1785ââ¬â1832) The beginning date for the Romantic period is often debated. Some claim it is 1785, immediately following the Age of Sensibility. Others say it began in 1789 with the start of the French Revolution, and still, others believe that 1798, the publication year for William Wordsworth and Samuel Taylor Coleridgeââ¬â¢s book Lyrical Ballads, is its true beginning. The time period ends with the passage of the Reform Bill (which signaled the Victorian Era) and with the death of Sir Walter Scott. American literature has its own Romantic period, but typically when one speaks of Romanticism, one is referring to this great and diverse age of British literature, perhaps the most popular and well-known of all literary ages. This era includes the works of such juggernauts as Wordsworth, Coleridge, William Blake, Lord Byron, John Keats, Charles Lamb, Mary Wollstonecraft, Percy Bysshe Shelley, Thomas De Quincey, Jane Austen, and Mary Shelley. There is also a minor period, also quite popular (between 1786ââ¬â1800), called the Gothic era. à Writers of note for this period include Matthew Lewis, Anne Radcliffe, and William Beckford. The Victorian Period (1832ââ¬â1901) This period is named for the reign of Queen Victoria, who ascended to the throne in 1837,à and it lasts until her death in 1901.à It was a time of great social, religious, intellectual, and economic issues, heralded by the passage of the Reform Bill, which expanded voting rights. The period has often been divided into ââ¬Å"Earlyâ⬠(1832ââ¬â1848), ââ¬Å"Midâ⬠(1848ââ¬â1870) and ââ¬Å"Lateâ⬠(1870ââ¬â1901) periods or into two phases, that of the Pre-Raphaelites (1848ââ¬â1860) and that of Aestheticism and Decadence (1880ââ¬â1901). This period is in strong contention with the Romantic period for being the most popular, influential, and prolific period in all of English (and world) literature. Poets of this time include Robert and Elizabeth Barrett Browning, Christina Rossetti, Alfred Lord Tennyson, and Matthew Arnold, among others. Thomas Carlyle, John Ruskin, and Walter Pater were advancing the essay form at this time.à Finally, prose fiction truly found its place under the auspices of Charles Dickens, Charlotte and Emily Bronte, Elizabeth Gaskell, George Eliot (Mary Ann Evans), Anthony Trollope, Thomas Hardy, William Makepeace Thackeray, and Samuel Butler. à The Edwardian Period (1901ââ¬â1914) This period is named for King Edward VII and covers the period between Victoriaââ¬â¢s death and the outbreak of World War I. Although a short period (and a short reign for Edward VII), the era includes incredible classic novelists such as Joseph Conrad, Ford Madox Ford, Rudyard Kipling, H.G. Wells, and Henry James (who was born in America but who spent most of his writing career in England), notable poets such as Alfred Noyes and William Butler Yeats, as well as dramatists such as James Barrie, George Bernard Shaw, and John Galsworthy. The Georgian Period (1910ââ¬â1936) The Georgian period usually refers to the reign of George V (1910ââ¬â1936) but sometimes also includes the reigns of the four successive Georges from 1714ââ¬â1830. Here, we refer to the former description as it applies chronologically and covers, for example, the Georgian poets, such as Ralph Hodgson, John Masefield, W.H. Davies, and Rupert Brooke. Georgian poetry today is typically considered to be the works of minor poets anthologized by Edward Marsh. The themes and subject matter tended to be rural or pastoral in nature, treated delicately and traditionally rather than with passion (like was found in the previous periods) or with experimentation (as would be seen in the upcoming modern period).à The Modern Period (1914ââ¬â?) The modern period traditionally applies to works written after the start of World War I. Common features include bold experimentation with subject matter, style, and form, encompassing narrative, verse, and drama. W.B. Yeatsââ¬â¢ words, ââ¬Å"Things fall apart; the center cannot holdâ⬠are often referred to when describing the core tenet or ââ¬Å"feelingâ⬠of modernist concerns. Some of the most notable writers of this period, among many, include the novelists James Joyce, Virginia Woolf, Aldous Huxley, D.H. Lawrence, Joseph Conrad, Dorothy Richardson, Graham Greene, E.M. Forster, and Doris Lessing; the poets W.B. Yeats, T.S. Eliot, W.H. Auden, Seamus Heaney, Wilfred Owens, Dylan Thomas, and Robert Graves; and the dramatists Tom Stoppard, George Bernard Shaw, Samuel Beckett, Frank McGuinness, Harold Pinter, and Caryl Churchill. New Criticism also appeared at this time, led by the likes of Woolf, Eliot, William Empson, and others, which reinvigorated literary criticism in general. It is difficult to say whether modernism has ended, though we know that postmodernism has developed after and from it; for now, the genre remains ongoing. The Postmodern Period (1945ââ¬â?) The postmodern period begins about the time that World War II ended. Many believe it is a direct response to modernism. Some say the period ended about 1990, but it is likely too soon to declare this period closed.à Poststructuralist literary theory and criticism developed during this time. Some notable writers of the period include Samuel Beckett, Joseph Heller, Anthony Burgess, John Fowles, Penelope M. Lively, and Iain Banks. Many postmodern authors wrote during the modern period as well.

Sports Nutrition Essay Example | Topics and Well Written Essays - 1000 words
Sports Nutrition - Essay Example It can best be described as a combination of swimming, soccer, rugby, wrestling and basketball. It is regarded as the oldest team sport in the world which is continuously contested at the Olympic Games. The game is normally played in seven- minute quarters; however, the regular fouls can extend the match time to approximately one hour of nearly non-stop action. In comparison to other team sports, water polo is a relatively shorter game. Upon the years, water polo has gradually been increasing in popularity especially among schools. Despite its popularity, the performance among Grace Lutheran water polo players has not been up to standards. Energy requirements for any kind of physical performance are critical. The energy stores in the liver are the main fuel for energy in the body. When the stores are inadequate, sport performance, timing and focus begin to suffer. Water polo players require a daily high carbohydrate diet to boost stamina and refill lost muscle and liver glycogen stores mainly during competition and training (Phillips, 2004). Allan (2004), states that the human body is normally designed to move by a sequence of coordinated muscle contractions. When the brain tells the body to move, the nerve signals trigger a massive release of muscular energy through a special molecule known as adenosine triphosphate (ATP). There are three systems in the body which create the ATP energy required for most of the physical activities, all the three systems are used for water polo in varying degrees (Cooper, 2003). To start with, the ATP-CP system plays a major role in the provision of energy for a five to seven second swim sprint in water polo (Panel, 1999). This is facilitated by a high energy molecule (creatine phosphate) which quickly delivers energy to manufacture ATP. Creatine phosphate is largely stored and readily available in the muscle fibers. This makes it the main supplier of energy during the commencement of water polo game. However, other suppliers of energy come in after a short duration of time (30 seconds). Due to the fast depletion of CP, the short period of water polo should be followed by a rest period to ensure that the CP that was depleted in the muscles is restored. Usually, no oxygen is required hence referred to as anaerobic exercise. Another energy producing system known as anaerobic glycolysis comes in after the depletion of energy using the ATP-CP system. It produces the ATP needed to continue the muscular contraction during execution of water polo skills. The break down of glycogen takes place with little requirement of oxygen. The glycogen utilized for this process is found in the liver and in the muscles (storage form of sugars in the diet). Normally, if a water polo player swims at a fast pace after the first 8-10 seconds, there is usually a delay in time when ATP formed from creatine phosphate runs out. Brian (2003), states that anaerobic glycolysis manufactures adequate ATP for a prolonged period of time (40 seconds up to 2 minutes) unlike ATP-CP system and is usually dependent upon the training levels of the athlete. The process quickly delivers adequate ATP to allow the water polo player to keep up with the fast pace despite the low levels of CP. However, production of lactic acid

On the other hand, macro factors are those that have an indirect impact on the business, also known as PESTEL. It includes factors that create opportunities and threats to business and is categorized as the far environment. These include variables such as political, environmental, socio-cultural, technological, economic and legal. (ii) The purpose of macro environment analysis is to determine the opportunities and threats to the farming industry as a whole and those outside the control of the company. External factors that affected the agricultural industry includes economic, technological, socio-cultural, environmental and political. All factors were considered as they play a part in determining the overall business environment. Economic factors include inflation rate, growth in spending power, exchange rates and economic growth. Opportunities can be that higher national income growth may boost demand for a fir m's products and chances for expansion increases. On the other hand, a strong currency may make exporting more difficult as prices in terms of foreign currency rises. Also inflation may provoke higher wage demands from employees and raise costs. With respect to technological factors, internet played a crucial role and gave way to online orders and delivery systems. Opportunities in the future may include complex operational systems installation that may cut down on labor costs, improve quality and lead to new innovations and make it attractive as a segment. Threats can be the probable advancement of technology making prior systems obsolete. Socio- cultural factors played an equally important role in farming industry. Change in trends where consumers demand for fresh products provided business opportunities to farmers and provide scope for innovation. Entertainment dimension added onto the development of this industry. However, trends changes and there exist a niche market that deman ds such products which might get concentrated. This can thus pose as a threat to agricultural industry. In Environmental factors, Physical factors of climate relief and soils affected the business positively. With major climate changes and greater environmental awareness this external factor is becomes a significant issue for firms to consider. However, going for environmental friendly products and processes can create business opportunities now and in the future as well.

United States Economy on the rebound Essay Example for Free
United States Economy on the rebound Essay Forbes. com reported that the United States economy recovered from an economic slump by 3. 4 percent in this yearââ¬â¢s second quarter. It is reportedly a highly-favored performance in more than a year. The major force believed to be the largest attributing factor to this economic resurgence is the reinforcement of business spending. (AVERSA, 2007) The 3. 4 percent growth rate is said to be a bit higher than the 3. 2 percent estimated by Wall Street. (Daily Times , 2007) Despite the seemingly favorable pace, analysts predict that this show of strength may not continue for the rest of the year. The economic upswing can be credited to the rise of exports, a significant improvement in the global business scene, and a decline in consumer spending. Exports have reportedly grew to 6. 4 percent while imports dropped by 2. 6 percent. (Daily Times , 2007). Consumer expenditure is one of the factors that fuels economic expansion. However this component does not have too much of an impact. End user spending went up only 1. percent as opposed to 3. 7 percent in the first quarter. It is reportedly the weakest since late 2005. (Daily Times , 2007) The real estate sector also experienced a dip as real estate investments fell to 9. 3 per cent although not as low as the first quarter dip of 16. 3 per cent. Analysts are predicting that there are certain risks as brought on by this development. This is because the drop in real estate investments may have impacts of still unknown nature (Daily Times , 2007). Inflation rate is also among the meter sticks of economists. Inflation rates are better from the 2. 4 percent in the previous quarter to only 1. 4 percent in the next quarter; this is said to be the slowest rate since 2003. (Daily Times , 2007) It is expected that the American people will have more buying power resulting from the better condition of the economy and of the United States dollarââ¬â¢s show of strength. Personal incomes of the American people have increased by . 40 per cent or $47. 3 billion. Disposal personal incomes climbed up to $37. 6 billion or . 0 per cent according to the Bureau of Economic Analysis or the BEA. (Armah Rankin, 2007) Wages and salary payments have increased to a high $24. 9 billion in May. This is in stark contrast to the dip of $36. 4 billion in April. (Armah Rankin, 2007) In addition to the above factors, the real gross domestic product or the yield produced by industries and property in the United States, went up to 3. 4 per cent per annum. Elements that caused this increase in the GDP include upbeat inputs from personal expenses for services, exports, and nonresidential structures. Also lending a hand were federal government spending, state and local government expenditure. (Mannering, 2007) The uphill inclination of the economy will cause improvements in the financial stature of many Americans. Analysts and ordinary people alike expect that more and more people will be confident in their finances such that they will be able to afford more luxuries. This may cause a change in the lifestyle of many Americans. Banks are always on hand to offer loans that many people think will help alleviate their financial situation. People should be wary of this and be aware of the impact that interest rates may have on their finances, should they start to fail in making payments. In spite of the uphill trend of the economy, business analysts are hopeful but are still watchful of the possible outcome. Notwithstanding this positive development of the economy, it is still and always advisable to be careful of oneââ¬â¢s spending habits. People should take advantage of the financial freedom that this economic condition will lend so that they can prepare for their future. Instead of spending a big portion of their hard-earned money on luxuries that will gradually deplete their monetary reserves because of expenditures such as taxes and depreciation, people should make it a habit to set aside a sum of money for investment instruments. Investment instruments such as pension plans, trust funds that will help them maximize their moneyââ¬â¢s earning potential and help them secure their future or make it easier for them to afford other comforts such as leisure trips out of the country or a new vacation home. Whatever state the economy is in, it is always wise to plan for the future. Those who are new in investing can seek the help of professionals who can aid them in making the right investment decision. One must always take advantage of investment tools that will help him enjoy and maximize the benefits of his hard-earned money. It is also important that people learn to stay debt-free. If they are already in debt, they should seek help of financial advisers on how to get out of debt in such a way that they can still live a comfortable life.

Software Outsourcing: Is the End of the American Programmer Near? :: Outsourcing Software Jobs Globalization
Software Outsourcing: Is the End of the American Programmer Near? Introduction Former U.S. Presidential candidate Ross Perot once warned of the U.S. entry into the North American Free Trade Agreement as "a great sucking sound" as U.S. jobs "run" to Mexico. 1 Many Americans feared that cheap labor in Mexico would cause many Americans to lose their jobs as U.S. companies could find cheaper labor south of the border. In the ten years since the beginning of NAFTA, the U.S. job market has remained strong. 2 The types of jobs may have changed to a certain degree, but the number of jobs has only increased despite the fears of many. Today, many people are worried about the effects of the outsourcing of software upon U.S. jobs. Many people fear the "great sucking sound" as software jobs are outsourced to cheaper labor in foreign countries, such as India. U.S. legislators have faced the issue and are trying to reduce the incentives of companies to hire workers abroad. 3 There are many fears and uncertainties about globalization and the new global economy as many people f ear change and competition from cheaper foreign labor. Are these fears justified? Is the American job market going to collapse? In the words of Ed Yourdon, has the "decline and fall of the American programmer" come? 4 Also, is it ethical to outsource software for cheaper labor? The Global Economy and Modern Economics In recent years, especially with the rise of the World Wide Web, there has been a steady increase in a more global economy. New technology has made the world more connected. It is much easier and less costly to communicate and interact with people around the world. Telecommunications makes it more possible to work from a remote location rather than working in a specific building. Cellular phones, laptops, and wireless internet make it much more possible to work from just about anywhere. The rise of the global economy has also led to the rise of employment outsourcing. Labor is being treated much like goods. Employers are seeking to lower costs and increase profits. As with the practice of buying cheap materials in foreign markets, companies are increasingly trying to buy cheap labor in foreign markets. From the standpoint of modern economics, this is just supply and demand. Therefore, does this mean that much of the labor in the U.S. will be imported from other countries?

Building Defects
Introduction: Decay and deterioration can happen in a building for any number of reasons. The first being poor repair and maintenance of the building over its life by users or those responsible for its maintenance such as a landlord etc. It can also mean that there were original problems with the building that impair its ability to function as intended, these may not have been uncovered during the snagging process at the end of the construction stage.These building problems are referred to as defects, depending on the type of contact most contracts have a 12 month defect period, this enables the users (and funders) to live in the building through the different seasons and see if any problems occur. A latent defect is after the 12 month defect period has lapsed and the new building shows signs of problems that are so significant that they can stop its functionality (a latent defect period can last up to 12 years on some contracts). Please find below some common reasons for defects: * Design IssuesDesign professionals (such as architects or engineers) could perhaps specify material or equipment that cannot perform as intended. For example: a geological survey that does not cover enough areas on a site could mean that the subsoil is not consistent across the site and therefore could eventually cause subsidence in the building. The architectââ¬â¢s motivation for the design may be with the building form, function or aesthetics but the completed design could result as a defect as any cost considerations or value engineering if not well planned, managed and coordinated could result in a defects.The use of inferior building materials can cause problems such as windows that leak or fail to perform and function adequately, even when properly installed. Leaking windows are a common defect and prevention requires good workmanship. * Site supervision during construction period Poor supervision during the construction period can result in poor quality and sub standard wor kmanship. For example: this can often manifest in water infiltration through some portion of the building structure (cracks in oundations, floor slabs, walls, dry rotting of wood or other building materials), electrical and mechanical problems, plumbing leaks and back-ups, lack of appropriate sound insulation and fire-resistive construction between adjacent housing units, etc. The above can prevented with a good Quality Assurance process in place that ensures that all trades are well supervised on site, accurate records are kept on workmanship (this can include pictorial evidence) and guidance is given to all staff on the quality expectations that have to be achieved on site.The traditional role of Clerk of Works should also be used to ensure that all measures are met on site level. * Maintenance No building lasts forever. Day to day planned maintenance of a building is required to ensure that it prevents any problems in the future. Poor planned maintence can cause defects to occur in buildings that would have performed well had they been cared for properly. For example: a master plan for the buildings mechanical and electrical (M&E) equipment to be replaced (such as Boiler replacements, lighting upgrades, ICT Category cabling upgrades etc. also phased window or roof replacement schedule to ensure that all that entire building envelope is protected to protect from the elements. If maintenance of buildings are not kept up to date then in some contracts ââ¬Ëlatent defectsââ¬â¢ would not be honoured as the users have not maintained the works that were carried out in line with the contract therefore the contractors would not be obligated to rectify any defective works. * Service installationSome equipment requires regular servicing under the terms of its guarantee. For example: If a boiler that has been installed with a 10 year warranty is not annually serviced then the manufacture can advise that the user did not meet their obligations and therefore any replacement in the 10 year period would fall to the user to fund. Common Defects found in Low-Rise Housing: Please see below mock defects sheets in relation to the defects outlined in ââ¬ËCommon Defects in Low-Rise Housingââ¬â¢.These outline the defect, the cause of the defect, the remedy required to rectify the defect and finally any supporting building regulations/guidelines that support this process.

The purpose of this is to keep both walls together at all times.A wall tie allows slight movement for expansion but if correctly fitted stops each wall acting independently of one another so therefore keeps the building strong and stable. | DEFECTIVE AREA: * Corroded and show signs of de-laminating (this is when the metal starts to peel and splinter) * Corroded due to water egress (decaying of the tie means loss of strength) * Corroded show signs of ferrous oxide (this is when the metal bubbles and expands) this can cause lifting and cracking the brickwork * Cavity walling that is blocked with decayed mortar that bridged the DPC. Poorly fitted wall ties (this means that it does not function as originally intended) * Incorrect wall ties used (there are 4 different types of wall ties ââ¬â each tie has its own best area for use)| DEFECTIVE CORRECTION REQUIRED: * Ties should be placed at 900mm centres horizontally and 450mm vertically * Sufficient lap of Damp proof course is required all round * Wall ties to be of a minimum size 5/m2 * Ensure that ties are as specified and are of the correct type * Use BS or BBA Certificated ties of length and type suitable for cavity width and purpose * Space ties in accorda nce with BS 5628: Pt 3: 2001.For example: the cavity width should be 50 to 300mm, number of ties 2. 5 per m2, 900 mm horizontally 450mm vertically and provide extra ties adjacent to openings * Check that there is a row of ties at every sixth course of bricks * Ties should be staggered and evenly distributed * Check that the horizontal spacingââ¬â¢s have the correct number of specified ties per m2 * Check that ties are at every block course within 225mm of opening | RELEVANT BRITISH STANDARD:| * BS:5628 Pt 3. 2001 | | | | | STAGE:A| WORKS/JOB SHEET NO. 1| LOCATION:Rear externals| DATE:26th May 2010| BRE REF NO.Defect Action Sheet 96| DEFECT: Mature trees too close | CAUSE: Poor design and specification | FUNCTION:Movement where a building is in close proximity of a mature trees. This is a common problem found generally in the following species Oak, Poplar, Ash, Plane, Willow and Elm although any very large mature tree close to a building can spell disaster. These trees require a c onsiderable amount of water to grow much of this is taken up by their root system. For example: a mature poplar can take up to 50,000 litres of water from the sub-soil each year.The more mature the tree the greater amount of water it requires. The outcome of the site survey and soil investigation should inform the decision on the type of substructure to be used for the proposed buildings in relation to soil type, saturation levels and lay of land e. g. sloping etc. It is recommended that buildings be built at least a distance equivalent to the treeââ¬â¢s height away from that tree to protect both the tree and the building although in some cases of Willow, Poplar and Elm the root radius can be twice that of the tree height. DEFECTIVE AREA: * The trees potential root radius has not been calculated correctly * Poor choice of substructure for the new building| DEFECTIVE CORRECTION REQUIRED: * Repair works require the retrospective installation of a root barrier (see attached diagram) . This means detailed surveys are required to identify were the tree roots are. If the tree has a Tree preservation order (TPO) on it then any damage to its roots could mean an appearance in Majesties court and a fine up to ? 20,000| RELEVANT BRITISH STANDARD:| * BS:5837 * Approved Document A & C * Tree Preservation Orders: A Guide to the Law and Good Practice 2000|STAGE:A| WORKS/JOB SHEET NO. 22| LOCATION:Flank wall| DATE:26th May 2010| BRE REF NO. Defect Action Sheet | DEFECT: Poor Mortars, Bricks, Blocks in sub-structure| CAUSE: Poor design and specification Poor site supervision| FUNCTION:Mortar is used a bonding agent to secure brick and block work. These three elements used together ensure that the building is sound, secure and water tight. | DEFECTIVE AREA: * Poor specification of an inferior brick and blocks that are engineered to support the loadings of the finished building is poor design planning.A poorly specified mortar could also be the reason that water could ingr ess the building this could lead to significant problems later for the building. * Poor site supervision of this area could mean that the mortar is poorly laid or not given enough time to set, or could even have been laid in the wrong temperatures such as Frosty weather. | DEFECTIVE CORRECTION REQUIRED: * The building may require additional support. For example: underpinning externally could support the substructure sufficiently enough to take the load away from the problem areas. The best method in this case is to pile and beam. This method stabilises the existing substructure by using piles installed either side ofà an existing wall. A small excavation is made below the ground level and a reinforced concrete needle beam is used to connect the piles and support the wall. * Reducing the distance between needle beams can accommodate very high loads. | RELEVANT BRITISH STANDARD:| * | STAGE:D| WORKS/JOB SHEET NO. 24| LOCATION:Internal/External various locations| DATE:26th May 2010| B RE REF NO.Defect Action Sheet | DEFECT: Notches and holes for services mis-positioned and oversized| CAUSE: Poor design Poor site supervision| FUNCTION:The location of holes and notches for services is very important in relation to the functionality and quality of finish to the end building. A misplaced large hole could lead incorrectly fitted lighting, heaters, light switches etc. | DEFECTIVE AREA: * Poor design drawings that are sent to site with the wrong measurements could mean that the location and shape of the holes for services are installed as per the drawing. It is more lightly that this defect would be down to poor site supervision. This could mean that the inappropriate person has been tasked to carry out this work such as a labourer that does not have the skill to read drawings but was asked to install holes for services rather than an electrician or electricianââ¬â¢s mate (i. e. being supervised by the trade lead at all times)| DEFECTIVE CORRECTION REQUIRED: * If cau ght early enough this should not be a great problem to resolve on site.However, if this was left to practical completion were the building is being handed over to the user/occupier then the works to rectify could be much greater and could include the following: * Re-routing electrics and mechanical pipe works to suit correct dimensions * Repositioning of all electrical and mechanical equipment * No direct connection to main sewer therefore re routing all connections to bathrooms, kitchens and any sinks etc| RELEVANT BRITISH STANDARD:| * | STAGE:D| WORKS/JOB SHEET NO. 30| LOCATION:Door No. GF32| DATE:26th May 2010| BRE REF NO.Defect Action Sheet | DEFECT: Lintels in external walls: missing, damaged, bedding, insulation| CAUSE: Poor design and specificationPoor site supervision| FUNCTION:A Lintel is a piece of steel or concrete that is used as a support in walls. These are generally used above openings (such as windows or doors) in the wall to support the load above. Lintels are usual ly supplied with load bearing at each end for 100mm openings up to/including 1000mm, 150mm for openings up to/including 3000mm and 200mm for openings over 3000mm. For spans in excess of 1200mm, it is good practice to provide temporary support such as an Acro at every 1200mm point. DEFECTIVE AREA: * Poor design could mean that the location window or door opening is in a difficult position to properly fit the correct size lintel * Poor specification could mean that a concrete lintel is specified when the location requires a small and compact steel lintel * Poor site supervision could mean that the area were the lintel is to be installed in not supported prior to installation and therefore the floor above is already sagging with the load. Also installation of the wring lintel in time will show on the exterior and interior of the building. DEFECTIVE CORRECTION REQUIRED: * Lintels should be carefully bedded on a full mortar joint * Wall ties should be positioned in accordance with curren t building regulations * A damp proof course should be used for all lintels in external walls, and must be fixed in accordance with building regulations * In cavity construction, it is recommended that both internal and external leaves are taken up uniformly * It is good building practice to insert a flexible joint between the lintel and the top of the frame| RELEVANT BRITISH STANDARD:| * BS:12 * BS:882|STAGE:E| WORKS/JOB SHEET NO. 20| LOCATION:| DATE:26th May 2010| BRE REF NO. Defect Action Sheet 73 & 74| DEFECT: Floor joist quality and installation: not graded or marked, bowing and twisting, high moisture content and wet rot| CAUSE: Poor specification Poor site supervision| FUNCTION:A floor joist is a beam of wood that stretches from one side of the sub-floor to the other bridging the floor load bearers. They are the essential component to the foundation of each floor level and floor boards are laid onto of them to give a foundation to any floor covering.Wood should be marked Top/Bottom, be graded (for the load) and have a kite mark or brand number referring to BS: EN 14250. | DEFECTIVE AREA: * Poor specification of a floor joist can mean that the wood used is not the correct grading to support the load. This can mean that the floor in time will show effects of overload bowing and twisting are one of the signs. * Poor site supervision of this area could mean that the wood has not been stored correctly on site meaning that it is now warped and twisted and has high water content. If wet rot occurs it is generally at the bearings of timber joists in external walls.For example: the sole or head plates rather than in the studs. | DEFECTIVE CORRECTION REQUIRED: * An assessment on if there is any ââ¬Ëdead airââ¬â¢ within the cavity between the joists and the floor board. If so, then air bricks (to BS:493) can be installed into the external walls to allow air flow. If wet rot is localised in small area then minor repairs can be made * If poor ungraded wood has been installed then the floor will have to be taken up and reinstalled with the correct graded wood to ensure it complies with current building regulations. | RELEVANT BRITISH STANDARD:| * BS:EN 14250 * BS:493|Area H: Defect| Drains below foundations| Reason for Defect:| * Broken or damaged pipes *
