A Quantity Surveyor (QS) is a professional person working within the construction industry. In the fields of Architecture and Civil engineering, construction is a process that consists of the Building or assembling of Infrastructure The role of the QS is, in general terms, to manage and control costs within construction projects and may involve the use of a range of management procedures and technical tools to achieve this goal.

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. The 19th century of the Common Era began on January 1, 1801 and ended on December 31, 1900, according to the Gregorian calendar This article is about the skilled manual worker meaning of the term for other uses see Tradesperson (disambiguation A tradesman is a skilled manual worker A guild is an association of craftsmen in a particular trade The earliest guilds were formed as confraternities of workers Because the tenders were each based on the same schedule of information, they would be easily compared to find the most suitable candidate.

The professional institution with which most English-speaking Quantity Surveyors are affiliated is the UK based Royal Institution of Chartered Surveyors (RICS) and Institution of Civil Engineering Surveyors (ICES). A professional body or professional organization also known as a professional association or professional society is an organization usually Non-profit, that exists The Royal Institution of Chartered Surveyors (RICS is an independent representative Professional body which regulates property professionals and surveyors

Although all QSs will have followed a similar course of education and training (for those entering the profession today, this is usually to degree level), there are many areas of specialisation in which a QS may concentrate. A degree is any of a wide range of status levels conferred by institutions of Higher education, such as universities, normally as the result of successfully completing The main distinction amongst QSs is between:

  1. Those who carry out work on behalf of a client organisation: often known as a "Private Quantity Surveyor", "Private QS" or "PQS".
  2. Those who work for construction companies: often known as a "Main Contractor's Quantity Surveyor".

The Consultant Quantity Surveyor

The functions of the Consultant Quantity Surveyor (traditionally referred to as the Professional Quantity Surveyor or PQS) are broadly concerned with the control of the cost on construction projects. The methods employed, however, cover a range of activities which may include cost planning, value engineering, feasibility studies, cost benefit analysis, lifecycle costing, valuation, and cost estimation. Value engineering is a systematic method to improve the "value" of goods and services by using an examination of function " Feasibility Study " is also the title of an episode from The Outer Limits television show Cost-benefit analysis is a term that refers both to a formal discipline used to help appraise or assess the case for a Project or proposal which itself is Some senior quantity surveyors are known as construction economists, cost engineers or commercial managers. The field of Cost Engineering is closely related to Quantity Surveying. The Association for the Advancement of Cost Engineering ( AACE International) defines Cost Engineering as "the area of engineering practice where engineering

Quantity surveyors control construction costs by accurate measurement of the work required, the application of expert knowledge of costs and prices of work, labour, materials and plant required, an understanding of the implications of design decisions at an early stage to ensure that good value is obtained for the money to be expended.

The technique of measuring quantities from drawings, sketches and specifications prepared by designers, principally architects and engineers, in order to prepare Tender/Contract Documents, is known in the industry as taking off. The quantities of work taken off typically are used to prepare bills of quantities, which usually are prepared in accordance with a published standard method of measurement (SMM) as agreed to by the QS profession and representatives of the construction industry. A bill of quantities (BOQ is a document itemising the materials parts and labor (and their costs required to construct maintain or repair a structure or device Many larger QS firms have their own in-house methods of measurement and most bills of quantities prepared today are in an abbreviated format from the one required by the SMM.

Generally a experienced surveyor would facilitate all the skills available to minimise additional costs to project and maintain a first class service for customers

The Contractor's Quantity Surveyor

The Contractor's QS is responsible for the performance of operations that mirror those of the Owner's QS; i. e, the measurement and pricing of construction work, but specifically that actually performed by the Contractor (and the Contractor's Subcontractors) as opposed to the construction work described and measured in the Construction Contract between the Owner and the Contractor. Such a difference in quantity of work may arise from Changes required by an Owner, or by an Architect or Engineer on an Owner's behalf. Typically, the settlement of a change (often referred to in a contract as a 'Variation'). (see, the following reference sources: "Fundamentals of Construction Estimating and Cost Accounting," by Keith Collier (2nd ed. ) (Prentice-Hall, 1987); "Construction Contracts," by Keith Collier (3rd ed. ) (Prentice-Hall, 2001) These two texts each contain a comprehensive Glossary.

The role of a contractors QS will extend further than the day to day running of building projects and will cover such other areas as sub-contract formation, forecasting of costs and values of the project, cash flow forecasts and the collation of the Operation and maintenance manuals of the project (O&M Manuals). This increase in the capacity of the surveying profession has led to an increased demand for qualified personnel and goes some way to explaining the popularity of related degrees at university.

Some contractors and others may attempt to rely on a general Accountant to deal with construction costs, but usually this is not effective, primarily because an Accountant does not have the technical knowledge to accurately allocate costs to specific items of work performed, especially at times prior to the particular work's completion as required to make accurate assessment of the amounts to be paid to the Contractor during the course of the work.

In the USA, instead of the title Quantity Surveyor, the appropriate title used may be Cost Engineer (see note below re: Titles). and this very important in the industry (Domino,2008)

Note

The use of the term "Professional QS" with regard to surveyors who work on behalf of a client does not indicate that those surveyors are, in some way, more professional than their counterparts working in construction companies, it is more a reflection of the fact that in the past it was less likely for a contractor's QS to become a member of a Professional body. As the number of contractor's QSs holding memberships of Professional organisations has increased, the "Professional QS" tag has become somewhat archaic although it continues in use as an easy identifier for those working on behalf of a client.

P as in 'Professional' QS tends to imply that a PQS operates with 'professional' indemnity insurance. This is as apposed to the CQS who as an employee or agent of the Contractor does not require such insurance.
