Thranekær Rådgivende Ingeniører

What Thranekær Rådgivende Ingeniører does

Thranekær Rådgivende Ingeniører A/S is a Danish partner-driven consulting engineering firm headquartered in Copenhagen, delivering advisory and technical services across the full construction project lifecycle — from early-phase analysis and procurement through engineering design, construction management and commissioning into operation. The firm is organized around four core service lines: Bygherrerådgivning (client advisory), Projektering (engineering design covering structural, electrical, HVAC, energy, indoor climate, fire safety, automation and environmental), Byggeledelse (construction management and DS3090 commissioning), and Forsyning (supply infrastructure for drainage, water, district heating, electricity and fiber). It serves public clients (Københavns Kommune, Region Hovedstaden, Forsvarsministeriets Ejendomsstyrelsen, Slots- og Ejendomsstyrelsen), almene boligselskaber (DAB, BO_VEST), private investors (Jyske Bank, ATP, Jeudan, Pensam, Thylander) and contractors across Denmark.

The firm operates through 13 offices nationwide — Copenhagen (HQ), Aalborg x2, Aarhus, Esbjerg, Grenaa, Holstebro, Lyngby, Randers, Thisted, Varde, Vejen and Viborg — and runs four retained sub-brands (DOMINIA, UCON, Børthy Schriver Lundemann A/S acquired 2025, Arkikon) under a "growth through organic and M&A" model where partners of acquired firms continue as co-owners. Technical stack is built on BIM-based design (Revit with 2D and 3D modeling), Molio-standard CTS and automation specifications (B2.400, B2.460, A115, CCS), DGNB certification frameworks for sustainability, advanced wastewater and climate-adaptation modeling tools, and indoor-climate simulation for CO2, ventilation, daylight and thermal performance. Demonstrated sustainability leadership includes DGNB Gold certifications on Uddannelsescenter Bispebjerg, Daginstitution Else and Arenakvarterets Skole, plus Københavns Kommune's 2019 building prize and public-vote prize for Axel Towers.

Revenue is generated on professional-services fees billed per project by scope, complexity and duration — there is no public pricing or productized offering. Contract values range from 11.3 mio. kr. for smaller assignments to +3 billion kr. for the 2024-2030 Danmarks Nationalbank renovation mandate; other major engagements include Damhusengens Skole (525 mio. kr.), Arenakvarterets Skole (711 mio. kr.), BO_VEST Moserne (620 mio. kr., 2023-2027), Axel Towers (1.3 billion kr.) and Oehlenschl\u00e6gersgade Skole (325 mio. kr.). The go-to-market is direct sales via tender processes, strategic partnerships (notably the TRUST framework with Byggeri København) and repeat mandates; services are exclusively direct, with no intermediaries or channel partners. Geographic expansion into Jutland (2026) and the Aalborg office launch (April 2026, 7 staff) mark the most recent growth moves.
