Nordby Maskin

What Nordby Maskin does

Nordby Maskin AS is a privately held, family-owned Norwegian infrastructure construction contractor founded in 1989, headquartered in Åsgreina/Nannestad near Oslo Airport. The company operates as a totalentreprenør (total contractor) with seven integrated core service lines: groundwork and road construction, water and sewage, infrastructure building, landscape gardening, concrete work, recycling and soil production, and No-Dig trenchless pipe renewal. It also runs an in-house design and surveying department (prosjektering og landmåling) that supports integrated design-build delivery, and operates a circular materials business through the Slettmoen Bioterminal and Østli Pukkverk quarry producing recycled aggregates, soil products, and energy chips. The technology stack centers on a fleet of approximately 100 construction machines — 70 of them excavators — equipped with Leica Geosystems MC1 GPS machine control and 3D terrain modeling, and on specialized No-Dig equipment including three Grundoburst pipe bursters and a Grundodrill 28N horizontal directional drilling rig. Automated Rototilt QuickChange couplers are fitted to 15 machines and 32 attachments to improve operator safety and efficiency.

The business model is project-based and dual-channel: direct contracts with private developers and enterprises (e.g., CTS Nordic/Green Mountain at the 400M NOK OSL-Hamar Datasenter, Digiplex Fetsund 133.5M NOK, Mestergruppen at Høgåsen, Peab at Gystadmyra, Skanska, Ø.M Fjeld) combined with public-sector revenue from 5-year municipal framework agreements with Gjerdrum, Nannestad, Hurdal, Nes, and Ullensaker, and competitive public tenders for agencies such as Statens Vegvesen and Nedre Romerike Vannverk. Customers span municipal infrastructure, hyperscale data centers, healthcare (LHL-Klinikken), aviation (Norwegian Air Shuttle), education (Oslo kommune), and real estate development. A secondary revenue stream comes from unit-priced material sales (gravel, sand, soil, aggregates, energy chips) at the Slettmoen Bioterminal, with publicly disclosed per-tonne pricing.

The company serves the Romerike and greater Oslo/Akershus region with a workforce of over 200 employees and is led by CEO Kristian Tangen, with family involvement through Karl Martin Nordby (Business Development) and Karl Kristoffer Nordby (Project Management on the OSL-Hamar engagement). Strategic positioning emphasizes modern fleet technology, in-house design capability, and circular-economy material handling as differentiators versus general regional contractors.

Core offering

Nordby Maskin is a total contractor for infrastructure construction, delivering groundwork/excavation, water and sewage systems, infrastructure buildings, landscape gardening, concrete work, recycling and soil production, and No-Dig trenchless pipe renewal for public and private sector clients in the Oslo/Akershus region. It combines in-house design, surveying, and execution with a modern fleet of ~100 construction machines to act as a one-stop infrastructure partner under framework agreements, total contracts, and unit-price tenders.

Product overview

Nordby Maskin is a total infrastructure contractor offering a diversified portfolio of seven interconnected core services: Grunnarbeid (groundwork/excavation), Vann og avløp (water and sewage), Infrastrukturbygg (infrastructure building), Anleggsgartner (landscape gardening), Betongarbeid (concrete work), Gjenvinning og jordproduksjon (recycling and soil production), and No-Dig (trenchless pipe renewal). The company operates as a total contractor with in-house design (Prosjektering og landmåling) and surveying capabilities, enabling integrated project delivery combining design and execution. Key technology features include GPS machine control on excavators (Leica MC1 platform) and Rototilt QuickChange automated quick-coupler systems. The recycling operation (Slettmoen Bioterminal and multiple production sites) processes and resells construction masses and soil products, creating a circular resource loop between excavation projects and new construction. Projects range from small municipal contracts to large-scale infrastructure projects such as data centers (OSL-Hamar, Digiplex) valued at hundreds of millions of Norwegian kroner.
