The Association of South African Quantity Surveyors (ASAQS) Elemental Class Version 1– a BIM classification system – has been developed for architects to organise or tag elements and objects for construction requirements, products and activities. The classification system is derived from the ASAQS Guide to Elemental Cost Estimating 2016.

This is a significant step forward for BIM standardisation for construction projects in Africa. In this era of digital collaboration, it is not enough to decide on a single classification system for a specific aspect of a project. Instead, there is a need for a classification system that suits all parties involved on a project, and one that is suitable for the entire project lifespan.

The classification system gives quantity surveyors the opportunity to classify construction elements in different ways, not only as a system, and can help define BIM objects in a building. By standardising information using the ASAQS Elemental Class, communication among architects, specifiers, contractors and suppliers can be made easier for project members to collaborate and for building owners in better understanding their requirements, timelines and budgets.

It not designed to replace any other classification systems, but is a standard for designers to classify elements and objects for estimators and contractors. The ASAQS Elemental Class is the specifications standard for most construction buildings design, and contains a consistent work breakdown structure (WBS), classifying items of all scale from a substructure such as strip footings down through to products such as audio-visual installations.

The ASAQS Elemental classification was developed by the BIM Institute in partnership with ASAQS and endorsed by South African Institute for Architects (SAIA).
