The Australian Institute of Quantity Surveyors (AIQS) is the peak body for built environment cost professionals in Australia. AIQS provides a home for and supports quantity surveying professionals working across a range of fields including cost estimating, cost planning, contract administration, construction management and quantity surveying. Its principal mission is to establish and uphold professional standards, maintain uniformity in procedures, support industry education, and foster public faith in cost certainty and the quantity surveying profession overall.

Since 1971, our members have been dedicated to maintaining the highest standards of professional excellence and continuous development.

AIQS has Chapters across Australia and an international chapter that is split into two regions - Asia and Middle East.

AIQS is a company limited by guarantee and is an active member of the International Cost Engineering Council (ICEC) and Pacific Association of Quantity Surveyors (PAQS).

AIQS acknowledges the Gadigal people of the Eora Nation as the Traditional Custodians of the land upon which our office is situated. We pay respect to the elders past and present and emerging and celebrate the diversity of Aboriginal peoples and their ongoing cultures and connections to the lands and waters of NSW and across Australia.
