How to determine builder’s margin for HIA contracts

HIA’s contracts generally enable the builder to nominate a “builder’s margin” to be applied in certain circumstances that may arise under the contract.

A “builder’s margin” can be applied when using HIA contracts to protect your bottom line when unforeseen circumstances come up.  These could include hidden site conditions, variations and adjustments between prime cost item or provisional sum.

Use this handy resource to calculate the appropriate builder’s margin when you encounter these kinds of issues on a residential building project. This article also includes helpful case studies and lays out the difference between a builder’s margin and your mark-up.

If you want to ensure you’re covered if things come up you couldn’t anticipate, this explainer is a great source of knowledge in easy-to-read format.
