Australian Institute of Quantity Surveyors (AIQS)


Quantity Surveyors (QS) encompass a range of professionals concerned with the management, estimating and planning of construction/building costs. These include construction cost consultants, construction cost managers, estimators, construction economists, building economists, cost planners, facility managers and project managers.

Quantity Surveyors work in the resources and infrastructure industries as well as the construction/building industry. They provides professional consultancy services for anyone involved in or entering the construction or building field; often acting on behalf of owners, principals or contractors.

The work of a QS includes all aspects of the construction cost cycle, including outdoor design. A new service now available to QS clients is the evaluation of sustainable development cost options.


The Australian Institute of Quantity Surveyors (AIQS) is the regulatory body in Australia for the Quantity Surveying profession, and as such publishes standards, practice notes, textbooks and journals on all aspects of construction cost management. It also establishes competency standards for the QS profession and requires all members to observe a strict code of professional conduct. This includes the possession of appropriate levels of professional indemnity insurance and continuing professional development.

The first QS Institute was established in 1908 in NSW and the modern AIQS was incorporated in 1971. The AIQS is a national body with an international reputation, with one quarter of its members working overseas.

Full or corporate (Member – MAIQS) membership of the AIQS is usually obtained by graduating from an AIQS-accredited degree course, completing two years of supervised work experience and passing an Assessment of Professional Competence (APC) panel interview.

Fellows of the AIQS (FAIQS) and Life Fellows (LFAIQS) represent the most senior and experienced level of corporate membership.

Practising QSs without appropriate tertiary qualifications may be admitted as Affiliate Members of the AIQS, and, after certain experience requirements, may later be admitted to corporate membership after passing the APC.
