What Aas-Jakobsen does

Aas-Jakobsen (Dr. Ing. A. Aas-Jakobsen AS) is a Norwegian civil engineering consulting firm founded in 1937 by Dr. Ing. Andreas Aas-Jakobsen and headquartered in Oslo. The firm specializes in advanced bridge engineering — particularly long-span suspension and cable-stayed bridges — alongside structural engineering, BIM-based building design, and complex infrastructure advisory. With approximately 160 employees and offices or project presence in Norway, Chile, Turkey, Thailand, and Canada, Aas-Jakobsen has built a globally recognized niche, with lead-designer roles on the 1915 Çanakkale Bridge in Turkey (the world's longest suspension bridge) and the Chacao Bridge in Chile, plus major Norwegian projects including Nydalsbrua and Oslo Airport's T2 terminal. Its client base is anchored by Norwegian public-sector infrastructure owners (Statens vegvesen, Avinor, Bane NOR) and tier-one contractors such as Skanska.

The firm's core technical assets are its proprietary engineering software and BIM process IP, including NovaDesign for concrete dimensioning and Trane, an in-house tool for tracking emissions on construction projects. Revenue is generated primarily through fee-based consulting engagements on large, complex infrastructure projects, with 2024 revenue of 470 million NOK and an adjusted operating result of 103 million NOK (~22% margin) — margins that are strong for an engineering consultancy and indicative of pricing power on specialist work. The firm has accumulated multiple IABSE awards, Betongtavlen 2023, and repeated Årets Anlegg honors, reinforcing its reputation in the Nordic and international bridge markets.

In June 2025, Aas-Jakobsen was acquired by Norconsult ASA, with completion in August 2025, marking the largest acquisition in Norconsult's history. The deal embeds the firm within a much larger Nordic engineering platform, expanding its commercial reach while preserving its specialist long-span bridge identity as a distinct competence center within the Norconsult group.
