Contracts in Norwegian Tunnelling

The aim is to share with colleagues internationally information on aspects of underground work. The publications are mainly focusing on technical issues. This time however, the publication concentrates on contracts and contract related issues.
The publication starts with an introduction to the Norwegian contract regime followed by papers relevant for this topic with contributions by important parties in a project implementation stage. Also included are examples of partnering and target price contracts as well as observations from three sub sea tunnelling projects.
Contract disagreements are well known for contract partners in underground construction. Most matters are solved through discussions and internal negotiations between the contract parties, for some contracts however, this avenue is difficult. Organised mediation during project implementation is a method to be considered for selected projects. The technique is reviewed.
