Groth & Co Bauunternehmung

What Groth & Co Bauunternehmung does

Groth & Co Bauunternehmung is a family-owned German construction conglomerate operating under the parent Groth & Co. Bau- und Beteiligungs GmbH & Co. KG with three wholly-owned operating subsidiaries in Pinneberg (Schleswig-Holstein), Rostock, and Neustrelitz (Mecklenburg-Vorpommern). Founded in 1925, the group employs over 1,000 people and reported approximately €90 million in total construction output in 2021. It functions as a multi-discipline general contractor delivering services across Hochbau (structural construction), Ingenieurbau (civil engineering), Straßenbau (road construction), Tiefbau (underground/infrastructure construction), and Bahnbau (railway construction), with the Pinneberg location alone accounting for ~400 employees.

The company's core technology is Building Information Modeling (BIM) deployed across all three locations, including digital twin construction planning, a Common Data Environment (CDE) for cross-discipline collaboration, and BIM-enabled issue tracking. Specialized technical capabilities include the Leica iCON pave 3D asphalt compaction control system (deployed on a Vögele 1900-3i paver), a patent-registered EMV-shielded prefabricated building component, and the KRC cold recycling method using 85% reclaimed asphalt pavement. BIM is positioned as a differentiator for clash detection, multi-discipline coordination, and billing integration.

The business model is project-based contract delivery: GROTH bids on public tenders (state road authorities, municipalities) and negotiates direct contracts with utilities, housing companies, port authorities, and regional airports. The group serves five primary verticals — public sector/municipalities, road and infrastructure authorities, energy and water utilities, port and maritime operators, and housing companies/real estate developers — with the largest named customers including LBV-SH (Schleswig-Holstein road authority), Rostock Port, Caliqua Powertec, Eurawasser, Neubrandenburger Stadtwerke, Neuwoges, and Hamburg Airport (via ARGE joint venture with KEMNA). No public pricing exists; each project is priced competitively or via direct negotiation. Marketing is regional and employer-brand-focused (LinkedIn, multi-location Instagram accounts, sports club sponsorships, mobile bus advertising, university career fairs). The company is pre-qualified (PRÄQ), ISO 9001 certified, SCC** certified, and DVGW-certified — all gating credentials for German public tender work.
