Standards are not statute. They are purchased documents from Standard Norge that parties agree to, or that regulations refer to. We carry the designation, edition and scope, never the text.

• Norwegian building and construction contract

  NS 8405:2008Standard Norge

  The general execution contract between client and contractor in larger projects. It governs the parties' obligations, variation orders, the duty to give notice and its deadlines, extensions of time, liquidated damages, payment, takeover and final settlement. Missing a notice deadline is the most common reason a claim is lost.

• Simplified Norwegian building and construction contract

  NS 8406:2009Standard Norge

  The simplified execution contract, made for smaller and less complex projects. It has fewer and milder notice rules than NS 8405 and suits parties who do not want a fully formalised notice regime. Many small trade businesses meet this one first.

• General contract provisions for design and build contracts

  NS 8407:2011Standard Norge

  The design and build contract, where the contractor is responsible for both design and execution. The standard allocates design risk and governs functional responsibility, variations, the client's cooperation, takeover and defect claims during the guarantee period.

• Specification texts for building, construction and installations, part 1

  NS 3420-1:2024Standard Norge

  The shared language for describing and pricing work in Norwegian construction projects: the code system, measurement rules and tolerance requirements. When the specification builds on NS 3420, both parties know what the price covers and disputes over scope become fewer.

• Technical condition analysis for the sale of dwellings

  NS 3600:2018Standard Norge

  The method for the condition report accompanying a home sale: which building elements are examined, how thoroughly, and how condition grades are set. The standard underpins the requirements for condition reports in the property sales rules.

• Acoustic conditions in buildings, sound classes for building types

  NS 8175:2019Standard Norge

  Sound classes for dwellings, schools, kindergartens, hospitals and offices. The technical building regulations point to class C as the minimum level, which makes the standard the practical yardstick in both design and defect claims.

• Criteria for passive houses and low energy buildings, non-residential

  NS 3701:2012Standard Norge

  Energy criteria for passive houses and low energy non-residential buildings: heat loss figures, heating demand and requirements for building elements. It is used in public procurement and grant schemes where an energy level must be documented.

• Information management using BIM, concepts and principles

  NS-EN ISO 19650-1:2018Standard Norge

  The framework for ordering, delivering and managing digital building information across a building's whole life cycle. Public clients refer to the series in tender documents, and it governs who owns and updates the model.

• Local Government Act

  LOV-2018-06-22-83In force: 2019-11-01Sivilombudet

  The Act governs how municipalities and county authorities are organised, their elected bodies, meeting procedure, financial management, internal control and state supervision. It determines who may take a decision in a municipality and how that decision is made.

• Public Administration Act

  LOV-1967-02-10In force: 1970-01-01Sivilombudet

  The Act applies to the activities of administrative bodies and sets the rules on impartiality, the duty to provide guidance, advance notice, party access, reasons, appeal and reversal. It is the general procedural act of Norwegian public administration.

• Freedom of Information Act

  LOV-2006-05-19-16In force: 2009-01-01Sivilombudet

  The Act gives a right of access to case documents, journals and similar registers held by the administration, and states when access may be refused. It also applies to independent legal entities where the state or a municipality has controlling influence.

• Archives Act (Act on documentation and archives)

  LOV-2025-06-20-96In force: 2026-01-01Arkivverket

  The Act requires public bodies to document their activities and to keep archives ordered and properly stored, and regulates disposal, transfer to the National Archives and the preservation of private archives of particular value. It replaced the Archives Act of 4 December 1992 no. 126, repealed on 1 January 2026.
