Marthinsen & Duvholt AS

What Marthinsen & Duvholt AS does

Marthinsen & Duvholt AS is a Norwegian privately-held civil engineering and infrastructure contractor. The company delivers eight integrated service lines — road construction and rehabilitation, technical infrastructure (including data centers), water and sewage systems, site work, railway construction, rock and blasting, earthmoving, and tunnel construction — to public-sector clients across Norway.

Its entire revenue base is generated through competitive public procurement. Active customers are exclusively Norwegian government entities: Statens vegvesen (the national road authority), Oslo kommune (the capital municipality), and Vestfold fylkeskommune (a county municipality). The company acquires work by bidding on government tenders rather than through private commercial channels, and contracts are multi-year and project-based. Notable active engagements include the E18 Vestkorridoren E102 road project (4,600 MNOK, August 2023 to January 2030) with Statens vegvesen, the Fornebubanen light-rail "Seks entrepriser" contract (600 MNOK, May 2020 to December 2029) with Oslo kommune, and the Smørberg mainland-connection project (13 MNOK, May 2026 to November 2026) with Vestfold fylkeskommune.

The business model is revenue recognition over the construction life of each public-sector contract, with pricing determined via competitive bidding rather than published rates. The company emphasizes health/safety (HMS), sustainability, and quality as stated operational focus areas, and runs apprenticeship, skilled-trades, and professional career pipelines to support workforce capacity. Operating geographies are limited to Norway; no subsidiaries, parent company, M&A activity, funding rounds, or AI/technology platform disclosures are present in the available data.
