The name Quantity Surveyor (QS) is derived from the Bill of Quantities, a construction industry document which details the quantities of materials and labour, calculated from design drawings, necessary for a construction project.

Today in the world of construction, Quantity Surveyors are an integral part of the total construction team throughout all stages of development: concept, feasibility, design, documentation & tender, and construction. The Quantity Surveyor’s professional focus is on budgets, cost planning and financial/cost control.

Economic controls are both fundamental to the planning of a project and essential to its progress and successful completion. Cost planning & control should start from the very beginning of each construction project and earliest involvement of the Quantity Surveyor best ensures achievement of that critical value for dollar for all stakeholders.

The Quantity Surveyor consults with and provides a valuable service to other team members including building owners, engineers, design team, architects, builders, contractors, and construction units. The QS also liaises with allied parties such as financiers, accountants, suppliers, solicitors, insurers, and government bodies.

Quantity Surveyors may also be involved after construction with insurance cost estimates, tax depreciation schedules, and with legal mediation and arbitration if construction disputes arise. Refurbishments, renovations, alterations, tender submissions and assessments, and insurance claim estimates are other areas of engagement.
