Buildability in construction

Buildability is a pre-construction exercise that assesses designs from the perspective of those that will manufacture, install components and carry out the construction works. It should not be confused with value engineering (which is used to solve problems and identify and eliminate unwanted costs) though some processes are common to both activities.

In very broad terms, buildability should assess elements of the design in relation to:

It involves careful study and consideration of:

Advances in Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) as well as the introduction of Building Information Modelling (BIM) are immensely helpful in visualising many aspects of buildability. However, the availability of technology does not remove the need for engaging practitioners who have hard-won experience and awareness of on-site practicalities and potential pitfalls.

The contractor is often best placed to advise on issues of buildability, and some procurement methods, such as construction management, management contracting and design and build allow early appointment of the contractor to offer advice and feedback on design proposals as they develop.
