NS 8405:2004


Note: This standard has a new edition: NS 8405:2008

Corrigendums and amendments are bought separately.



The standard has been prepared for use in a contractual relationship in which one party (the contractor) undertakes to carry out building or civil engineering work (including installations, new building, maintenance, repairs and alterations) for another party (the client), in which most of the drawings, descriptions and calculations are to be provided by the client. The standard is suitable for contractual relationships in which the project’s scope or organisation indicates a need for formalised notification rules with strict consequences (preclusion of claims) if notification is omitted, or an extensive duty to coordinate the work with all the other players in the project. In contractual relationships where, due to the organisation or scope of the project, there are no such needs, NS 8406 Simplified Norwegian Building and Civil Engineering Contract is much more suitable. The standard has not been prepared for use in subcontractor relationships. Separate contract standards have been prepared for subcontracts.
