A quantity surveyor (QS) is a professional working within the construction industry concerned with building costs.The profession is one that provides a qualification gained following formal education, specific training and experience that provides a general set of skills that are then applied to a diverse variety of problems.[1] Predominantly these relate to costs and contracts on construction projects. Other areas in which QS find employment include property surveys for hidden defects on behalf of potential purchasers, running estates, valuing the mineral deposits for mining companies, selling property and even Leasehold Reform Act work.[1]There are around 75,000 professional QSs working in the UK.HistoryThe profession developed during the 19th century from the earlier "measurer", a specialist tradesman (often a guild member), who prepared standardised schedules for a building project in which all of the construction materials, labour activities and the like were quantified, and against which competing builders could submit priced tenders. Because all tenders were based on the same schedule of information, they could be easily compared so as to identify the best one.The professional institution with which most English-speaking quantity surveyors are affiliated is the UK-based Royal Institution of Chartered Surveyors (RICS). Others are the Chartered Institute of Building (CIOB), Quantity Surveyors International (QSi) and...

Introduction Quantity surveyors are employed in private practices, public offices and by contractors, and they undertake a great diversity of work. In more recent times, quantity surveyors are engaged increasingly in the financial management of contracts and ensuring that clients secure value for money and that the completed projects provide substantial added value to the client’s property asset. Furthermore, they are sometimes engaged as lead consultants for large projects, where they are responsible for the delivery of all professional services from inception to completion. The need for quantity surveyor became evident as building work increased in volume and building clients became dissatisfied with the method adopted for settling the cost of the work. General contractors became established during the period of the industrial revolution and they submitted inclusive estimates covering the work of all trades. Furthermore they engaged surveyors to prepare bills of quantity on which their estimates were based. In addition, the architect on behalf of the building owner usually appointed a second surveyor, who collaborates with the surveyor for the contractors in preparing the bills of quantities, which was used for tendering purposes. This was the origin of the independent and impartial quantity surveyor...

...A bill of quantities (BOQ) is an itemized list of materials, parts, and labor (with
their costs) required to construct, maintain, or repair a specific structure.
It is a document used in tendering in the construction industry in which materials,
parts, and labor (and their costs) are itemized. It also (ideally) details the terms
and conditions of the construction or repair contract and itemizes all work to
enable a contractor to price the work for which he or she is bidding.
The term Bills of Quantities (BQ) is defined in the SMM (Standard Method of
Measurement) as a list of items giving brief identifying descriptions and
estimated quantities of the works to be performed. The BQ forms a part of the
contract documents, and is the basis of payment to the Contractor.
Bills of quantities are prepared by quantity surveyors and building estimators, etc.
Bills of quantities are prepared by a “taking off” in which the cost of a building or
other structure is estimated from measurements in the Architects, Structural
Engineers, and other building consultants drawings. These are used to create a
cost estimate such as in regard to the square area in meters of walls and roofs,
the numbers of doors and windows, and systems as heating, plumbing and
electrics. Similar types of work are then brought together under one item, a
process known as "abstracting".

[edit] History
The profession developed during the 19th century from the earlier "measurer", a specialist tradesman (often a guild member), who prepared standardised schedules for a building project in which all of the construction materials, labour activities and the like were quantified, and against which competing builders could submit priced tenders. Because all tenders were based on the same schedule of information, they could be easily compared so as to identify the best one. As a profession quantity surveying emerged around the 1820s with one of the earliest QSs being Sir Henry Arthur Hunt[2] who was involved in work on the Houses of Parliament.[3] After the fire in 1834 that destroyed the old Palace of Westminister Henry Hunt came up with an estimate cost of £724,984...

...The Role of the Quantity Surveying Profession
The origins of the Quantity Surveyor (QS) profession can dated back during the 19th century where from the earlier "measurer", a specialist tradesman, who readied schedules for a building project in which all of the construction materials and labour activities and were quantified. Based on this information, competing builders could submit priced tenders. Because all tenders were based on the same schedule of information, they could be easily compared to one another, making it a much simpler way of being able to chose the best bid as it narrowed the variables down (Powell, 1996). While the QS profession owes its origin to the “measurer” it was until the 1820s that as a profession the QS profession began with Sir Henry Arthur Hunt being one of the original QS estimating the cost of the rebuilding of the houses of parliament. (Powel,1996)
Within today’s industry the QSs role in construction sectors can vary depending on what area they are deployed. The construction sectors I will explore are Building work, Building and Engineering services, Civil engineering, Heavy and industrial engineering.
Building work
During building work in modern construction it is not unusual for the 1st point of contact for a client to be with a QS. Cost management is one of the key areas of concern for clients in today’s industry and with QSs being value and cost experts in the construction industry it makes sense for...

QUESTION 3: Quantity Surveying Business Strategy
“If it’s not adding value, bin it.” [Source: Quantity Surveyors Division of The RICS (1998), The Challenge of Change: QS think tank 1998: Questioning the future of the profession, London: RICS Publication]
Quantity surveying is one of the most crucial professions in construction and building industry. Quantity surveyor, also known as Cost Engineer or Construction Economist works together with other professionals like architects, engineer, financiers, and solicitors and so on. A quantity surveyor is majorly involve in cost planning, preparing Bill of Quantities, project management, contract administration, preparing tax depreciation schedules and others that are relevant (AIQS, 2003). However, as the world has becoming more advance in technology and education, the role of quantity surveying is shrinking as many challenges appear in 21st century. Thus, a quantity surveyor is ought to adopt value of improvement practices in order to win the challenges and meet the needs of current demand for quantity surveying services. Quantity Surveyors Division of the RICS (1998) defined value as ‘a capability provide to a customer at the right time and at an appropriate price, as defined by customer.’
Quantity surveyors need to be alert of...

CHAPTER 3: DIAGNOSTICS AND REMEDIAL MEASURES
Diagnostic For Predicted Variable
Probems can occur when:
* Outliers exist among X levels
* X levels are associated with run order when experiment is run sequentially
Useful plots of X levels:
* Dot plot for discrete data
* Histogram /stem-and-leaf plot
* Box plot
* Sequence plot (versus time order)
Departures From Model To Be Studied By Residual
1. The regression function is not linear.
2. The error terms do not have constant variance.
3. The error terms are not independent.
4. The model fits all but one or few outliers,
5. The error terms are not normally distributed.
6. One or several important predictor(s) have been omitted from the model.
Diagnostic For Residuals
Six diagnostic plots to judge departure from the simple linear regression model
* Plot of residuals against predictor variable. (The plot should have a random scatter of plots)
* Plot of absolute or squared residuals against X.
* Plot of residuals against the fitted values.
* Plot of residuals against time or other sequence. (Should not display any trends)
* Plots of residuals against omitted predictor variables.
* Box plot of residuals.
* Normal probability plot of residuals. (Should lie along a straight line)
