(Hons) QS, Dip. in Eng., IEng., MIIES, MAIQS, MRICS Chartered Quantity Surveyor Contract Manager RICS - Assessor/Counsellor AIQS - Assessor/Counsellor 4 April 2015 Origin of Quantity Surveying    Origin of Quantity Surveying dated back to ancient Egyptian civilization who used to dedicate personnel to carry out estimates and costing for their magnificent structures and buildings (such as pyramids). Quantity Surveying developed in to a occupation during 17th century for the restoration of London after the Great Fire. In 1836 the Quantity Surveying profession received a recognition when the new Houses of Parliament of Great Britain, designed by Sir Charles Barry, became the first major public contract to be fully measured and tendered using detailed bill of quantities for financial accountability TRADITIONAL QUANTITY SURVEYING PRACTICE In olden days the duties of a Quantity Surveyor were limited to:a) measuring quantities or surveying quantities for proposed construction works to arrive the value of the proposed works and b) measuring quantities or surveying quantities to arrive the value of the completed works. TRADITIONAL QUANTITY SURVEYING PRACTICE This scope has been extensively evolved and currently the Quantity Surveyor has to undertake not only the above conventional Quantity Surveying works but to perform overall cost management role in the Construction Industry. Now the term Quantity Survey is evolving as Construction Cost Directors/Construction Cost Managers in the Construction Industry. The history of the Quantity surveyor from the middle of the seventeenth century. TRADITIONAL QUANTITY SURVEYING PRACTICE This traditional role, that is still practiced by some and especially by small to medium sized projects can be briefly described a measure and value system. Approximate estimates of the initial cost of building are prepared using a single price method of estimating, and where this cost was acceptable to the client then the design was developed by the architect. 1for Traditional Quantity Surveying activities) .TRADITIONAL QUANTITY SURVEYING PRACTICE Subsequently the Quantity surveyor would produce bills of quantities for tendering purposes. the work would be measured for progress payments and a final account prepared on the basis of the tender documentation (see Fig. 1. 5.Discharge and Final Accounts 10.

Advice on cost limits and budgets. if you are entering into a realty investment that involves construction. you need a well defined budget.2. There is one thing that is definite. You do not want to be ball parking the figures particularly if you are going to be arranging financing to carry out the construction. . Refer module COST STUDIES . with no money to carry on. If you don’t then you could end up with a building partially finished. and end up in a most disastrous financial situation.It is imperative that you know your construction budgets limits. Also commonly referred to as "cradle to grave" or "womb to tomb" costs. refers to the total cost of ownership over the life of an asset. Whole life costing Whole-life cost.3. or Life-cycle cost (LCC). Refer module COST STUDIES . 4. Value Engineering Value Engineering can be defined as an organized approach to providing the necessary functions at the lowest cost From the beginning the concept of value engineering was seen to be cost validation exercise. Refer module COST STUDIES . The straight omission of an enhancement or finish would not be considered as value engineering. which did not affect the quality of the product.

It cannot be ignored –Sir Micheal Lathem The Quantity Surveyor should advice on risk in construction and take steps to manage the risk at minimum cost.
