This document provides an introduction to the role of a Quantity Surveyor (QS). It discusses that a QS calculates materials needed, manages construction costs, and works in private practice, for local authorities or contractors. A QS applies building economics at the planning stage, prepares bills of quantities from plans, analyzes tenders, and provides cost consulting. They are involved at various construction stages from estimating budgets to valuations. The document also discusses tenders, tender drawings, bills of quantities, construction drawings, and common building materials.

7. The various stages of cost planning during
the design & construction phases
Preliminary Estimate

Cost Check
Tender Reconcilation
Post-Contract Cost Control
Using a single-price method of
estimating
Based upon elemental analysis evolving
cost target
Evaluating the design in term of the
cost target
Comparison of the accepted tender with
the final cost plan
The control of cost during construction
