Quantity Surveying Services

What is a Quantity Surveyor?

Quantity surveyors are the financial consultants of the construction industry whose training and experience qualify them to advise on cost and contractual arrangements and to prepare contract documents. They act in liaison with architects, consulting engineers and contractors to safeguard the client's interest. They are independent experts who operate in a specialised area of the construction industry. Quantity surveyors are expected to maintain the highest level of professionalism towards all parties involved, thus ensuring fair and accurate finalisation of projects.

Why Employ a Quantity Surveyor?

o               To establish an initial construction budget and estimate construction costs before expensive design development time has been undertaken.

o               To ensure the most cost effective design solution.

o               To monitor costs during the design, development and construction stages and take action to keep costs under control.

o               To ensure that fully detailed tender documentation, including proposed construction contracts are prepared to minimise risks to the Employer from variations and contractual claims.

o               To ensure that tenders are obtained under the optimum conditions of competition.

o               To give contractors the assurance that cost management will be carried out in an equitable manner; the confidence that a Quantity Surveyor is employed on the project allows tendering contractors to be more competitive.
