The main objective of this New Zealand Tunneling Society (NZTS) Guide is to provide broad advice to practitioners in New Zealand. This advice is designed to improve risk management practices for procuring tunnels and underground projects, and assist in their administration.Read more
This NZTS Guide is intended to be a companion to the ASCE ‘Geotechnical Baseline Reports for Construction’ guidelines, and the International Tunnelling Insurance Guide (ITIG) COP for Risk Management of Tunnel Works.
The understanding between the parties to a contract of the risks at the time of forming the contract is essential. This is so that risks (not just geotechnical risks) are clearly allocated; and financial provisions are made accordingly. All parties then understand the basis for changed conditions should they arise, minimising potential disputes.
