This document identifies the key contractual practice areas the ITA believes are fundamental for ensuring the success of subsurface construction projects.

The reason that this document has been prepared is because existing standard forms of construction guidelines and contracts do not adequately deal with the particularities of the subsurface environment. The ITA believes that the application of this framework will enhance the possibility of achieving the project objectives for all stakeholders.

This publication does not specify how each subject area should be resolved, for that is almost certainly a matter peculiar to each project – but recommends that the timely and appropriate consideration of all the matters raised in this publication is essential for the successful subsurface project delivery.
