What Kadesjös Ingenjörsbyrå does

Kadesjös Ingenjörsbyrå is a privately-held Swedish engineering consultancy founded in 1945 and headquartered in Västerås, operating with 51-100 employees under CEO Jonas Pettersson. The firm delivers consulting engineering across five service lines — project management, building design, installation (MEP), inspection, and energy/environment/sustainability — to a named client base that includes Mälarenergi, Boliden, Hitachi Energy, JM AB, Einar Mattsson, Locum, and construction primes PEAB, NCC, Ramböll, and Byggdialog. Domain specializations include healthcare ventilation, industrial and process engineering (notably mining and steel), and large-scale energy infrastructure.

The firm's technical toolkit combines industry-standard building-physics simulation (IDA ICE, HEAT2), energy analysis (EED), and BIM/3D modeling, with certified delivery under Swedish sustainability frameworks (Miljöbyggnad, Svanen) and shelter ventilation expertise. Its project portfolio spans multi-decade flagship programs including Mälarenergi's Block 7 CHP and Brista 2 energy-from-waste facilities, Boliden's Aitik mine, and international work such as the Swedish Embassy in Beijing and the Norway-UK power link. A 2024 industry award nomination and a 2025 Sustainability Report mark recent steps in external positioning.

The business operates as an independent, owner-managed consultancy, generating revenue on a project-by-project fee basis typical of Swedish engineering firms, with multi-year programs supplemented by recurring inspection and certification engagements. Long-tenured client relationships — several spanning decades — function as the primary retention mechanism, while partnering with major contractors extends reach into consortium bids without material direct-sales investment. The firm has no disclosed funding activity, M&A history, or external investors, indicating organic, internally-financed growth.
