DUTIES OF THE QUANTITY
SURVEYOR
• Quantity surveying is essential to estimate before the construction starts the probable cost of
construction for the complete work
• The construction cost includes cost of materials, cost of transportation, cost of labor, cost of
scaffolding, cost of tools and plants, establishment and supervision charges, cost of water, taxes and
reasonable profit of the contractor, etc.
• The estimate is required in inviting tenders for the works and to arrange the contract for a complete
project
BOQ
• PURPOSES OF BILL OF QUANTITIES
• Frequently, one of the principal functions of the client's quantity
surveyor is the preparation of bills of quantities, although a QS does
also perform a number of other functions
BOQ
•
Consideration will now be given to the main purposes of a bill of quantities.
1.
First and foremost it enables all contractors tendering for a contract to price on exactly the same information with a
minimum of effort
2.
It limits the risk element borne by the contractor to the rates he enters in the bill
3.
It prompts the client and the design team to finalize most project particulars before the bill can be prepared, ideally
with full production drawings and project specification.
4.
It provides a basis for the valuation of variations which often occur during the progress of the work
BOQ
5.
It gives an itemized list of the component parts of the building, with a full description and the quantity of each part,
and this may assist the successful contractor in ordering materials and assessing his labour requirements for the
contract
6.
After being priced it provides a good basis for a cost analysis, which subsequently will be of use on future contracts
in cost planning work
FUNCTIONS OF A PROFESSIONAL
QUANTITY SURVEYOR
The functions of a professional Quantity Surveyor (PrQS) are:
•The professional quantity surveyor is broadly concerned with procurement strategies, measuring
and costing construction projects.
•The methods applied, however, cover a range of activities which may include cost planning, value
engineering, value management, feasibility studies, cost benefit analysis, life-cycle costing, risk
analysis, tendering, valuation, change control, dispute resolution, claims management, project
management, cost estimation and value for money assessments.
FUNCTIONS OF A PROFESSIONAL
QUANTITY SURVEYOR
•The PrQS's traditional independent role on the team comprised of the client,
architect, engineers and project manager has given him/her a reputation and
appreciation for fairness. This, combined with his/her expertise in drafting and
interpreting contract documents, enables the quantity surveyor to settle issues, value
the works fairly and regularly, project final costs, avoid disputes and enhance the
effective progress of a project.
FUNCTIONS OF A PROFESSIONAL
QUANTITY SURVEYOR
•PrQS’s advise on the control of construction costs by accurate measurement of the
work required on a regular basis, the application of expert knowledge of costs and
prices of work, labour, materials and plant required, together with 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.
FUNCTIONS OF A PROFESSIONAL
QUANTITY SURVEYOR
• The technique of measuring quantities from drawings, sketches and specifications prepared
by Designers, principal 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 (BoQ), which
usually are prepared in accordance with a published Standard System of Measurement
(SSM) as agreed to by the QS profession and representatives of the construction industry.
FUNCTIONS OF A PROFESSIONAL
QUANTITY SURVEYOR
• This activity is usually completed before the commencement of work on site on a
traditional (BoQ) project. The contractor will then price this document in competitive
tender and will be paid on a monthly basis according to a measure undertaken on
site and applied to each specific work item.
FUNCTIONS OF A PROFESSIONAL
QUANTITY SURVEYOR
• QS’s are prevalent in many industries (not just construction) as they are
procurement and contract specialists with the ability to adapt to suit the form of
contract or types of work being undertaken.
