What Lagrange-twm does

Lagrange TWM GmbH is a German technical building services (Technische Gebäudeausrüstung) contractor founded in 1928 and headquartered in Kirn, Rhineland-Palatinate. It delivers HVAC, plumbing, sprinkler, industrial piping, electrical, and MSR/building automation services across four primary locations (Kirn, Hanau, Mannheim, Mainz) supported by four additional workshop support points, with a workforce of 207 employees. The firm's service portfolio spans industrial, commercial real estate, public/institutional, and private residential customers, including named reference projects for Berufsfeuerwehr Mannheim and TU Darmstadt. It is qualified to ISO 9001:2015 and ISO 45001:2018, and its leadership comprises Managing Directors Rolf Lagrange and Olaf Walter.

The company operates as a subsidiary of VINCI Energies Building Solutions (Gebäude.TECHNIK), embedding it within a larger European building-services network cited at approximately 30,000 experts that provides resource capacity, technical specialization, and cross-regional bid support. Revenue is generated through direct B2B project contracting — sales-led tenders, negotiated scopes, and project execution across new construction and refurbishment — with a high share of work performed by its own trades workforce rather than subcontractors. The offering is positioned as a full-scope, single-source TGA partner capable of integrating mechanical, electrical, and automation disciplines within a single project delivery.

The business model is project-based with pricing tied to scope, specification, and execution timeline under German construction-contract conventions. Customer segments are diversified across industrial clients, commercial real estate, public-sector/institutional tenders, and private residential projects, the latter increasingly incorporating regenerative energy technologies (e.g., heat pumps, photovoltaics) to align with German building decarbonization policy. Distribution is regional rather than national, with the four locations and four workshop support points functioning as execution hubs for service, warranty, and rapid-response work within their catchment areas.

Core offering

Lagrange TWM plans, installs and maintains energy and building technology systems for industrial, commercial, public-sector and residential clients in Germany. Its offering covers eight integrated technical building services trades — heating, climate/ventilation, sanitary, refrigeration, fire protection and sprinkler, industrial piping and plant construction, electrical engineering, and measurement/control/regulation (building automation) — delivered from a single provider with one coordinating point of contact across consulting, planning, execution, commissioning, training and after-sales service.

Product overview

Lagrange-twm offers a comprehensive portfolio of building technology services as a unified offering rather than distinct software products. The services include eight integrated technical disciplines: Heating Technology (Heizungstechnik), Climate and Ventilation Technology (Klima- und Lüftungstechnik), Sanitary Technology (Sanitärtechnik), Refrigeration Technology (Kältetechnik), Fire Protection and Sprinkler Technology (Brandschutz- und Sprinklertechnik), Industrial Pipe and Plant Construction (Industrieller Rohrleitungs- und Anlagenbau), Electrical Engineering (Elektrotechnik), and Measurement/Control/Regulation Technology (Mess-, Steuer- und Regelungstechnik). These services are offered as an integrated package from a single provider, coordinated by one contact person, covering the entire project lifecycle from consultation and planning to execution and maintenance for industrial, commercial, and residential buildings.
