What LM Byg does

LM Byg A/S is a Danish specialty contractor founded in 1987 and headquartered in Taastrup, Denmark, operating as a wholly-owned subsidiary of Pihl Holdings A/S (parent of Pihl Koncernen). The company focuses on concrete and shell construction (råhusbyggeri) — the structural envelope of buildings — for public, private and industrial clients primarily in the Greater Copenhagen and Zealand region. Its service portfolio spans in-situ cast concrete, precast element assembly, wood (CLT) structures, and steel structures, delivered under main (hoved-), large (stor-), total (total-), and trade (fag-) contracts. The company runs one of Denmark's largest in-house concrete production units, with over 200 employees and a stated track record of never having received a liquidated damages penalty (dagbod) for late delivery.

LM Byg's technology and product differentiation is anchored in low-carbon concrete — particularly deep co-development experience with Aalborg Portland's FUTURECEM, which reduces cement CO2 by up to 30% — and in-house developed concrete recipes, complemented by an emerging CLT timber capability demonstrated on signature projects like Marmormolen. Digital project management (BIM, 3D modeling, IKT-agreements) is applied across all phases, and the workforce is being systematically DGNB-certified to support sustainability-driven tenders. The company is part of the Pihlkonsortiet consortium with sister company Pihl & Søn A/S and civil engineering partner M.J. Eriksson A/S, enabling it to bid on totalentrepriser substantially larger than its standalone shell scope.

Commercially, LM Byg generates revenue through one-time, project-based construction contracts awarded via competitive tender. The consolidated Pihl Koncernen (LM|Pihl A/S) reported record revenue of DKK 1.83 billion in fiscal year 2024/25 (25% YoY growth), with pre-tax profit of DKK 60.5 million and equity of DKK 222.2 million. Customer mix is dominated by Danish public-sector clients (hospitals, water utilities, defense, prisons, municipalities) and institutional real estate developers (PFA, AP Ejendomme, Skanska, Carlsberg Byen P/S, M. Goldschmidt Ejendomme), with selective industrial wins (Novo Nordisk, AGC Biologics, Haldor Topsøe) and architect-led signature projects (BIG HQ, Kaktustårnene). No standalone LM Byg revenue figure is disclosed; the public revenue metric is for the consolidated group.

Revenue model

1. Construction contract revenue: Primary revenue from project-based construction contracts awarded through tender processes. Performs main contracts (hovedentrepriser), total contracts (totalentrepriser), large contracts (storentrepriser) and specialty contracts (fagentrepriser) within shell construction, concrete work, and related trades. One-time per-project contracts rather than recurring.
2. Consortium project revenue (Pihlkonsortiet): Revenue from large totalentrepriser delivered through the Pihlkonsortiet consortium (with sister company Pihl & Søn A/S and partner M.J. Eriksson A/S). LM Byg delivers the shell/råhus work while consortium partners handle other phases. Enables bidding on projects larger than LM Byg could handle standalone.
3. Renovation and refurbishment contracts: Revenue from major renovation projects (e.g., Albertslund Vest courtyard houses, Øresund Strandpark, Holbæk Havneby) including demolition, environmental remediation, new ground slabs, drainage, in-situ concrete work and full structural renovations.
