What BHK Tief- Und Rohrbau GmbH does

BHK Tief- und Rohrbau GmbH & Co. KG is a German specialist contractor for underground infrastructure, founded on 27 November 1990 by Böcker, Hermecke and Kreuscher (the initials forming the brand) and headquartered in Bremen with its registered office in Neubrandenburg. The company designs and executes pipeline construction for district heating, gas, water and pressure pipework, cable conduit installation for power and fiber optics, and complete utility connections for residential and commercial properties. Its technical differentiation sits in trenchless methods, including horizontal directional drilling (HDD), suction excavation (Saugbaggern), protective pipe jacking (Schutzrohrpressung) and pipe bursting, which minimize surface disruption on crossings of roads, railways, waterways and protected areas; network planning, BIM-ready documentation and district heating leak detection complete the offering.

The business operates project-based, lump-sum contracts acquired through public tenders and direct negotiation with established municipal utility and energy customers. Customer segments include municipal utilities (wesernetz Bremen, Hamburg Wasser), energy contractors (enercity Contracting Nord), grid operators and telecom providers, and private property owners seeking house connections. Pricing is bid-driven, based on scope, materials and labor, with no published tier model. BHK is a subsidiary of the Seier Gruppe (integrated 2022), retains operational autonomy, and is led by managing directors Robert Hormann and Paul Šrajbr (NRW, since September 2025). It currently employs more than 240 people across seven locations in Bremen, Bremerhaven, Hamburg, Neubrandenburg, Herford, Schwerte and Rheda-Wiedenbrück, holding DVGW GW 301/302/381, AGFW FW 601, AMS Bau and ISO 9001/14001/27001/50001 certifications.

Core offering

BHK Tief- und Rohrbau GmbH & Co. KG provides underground infrastructure construction services, specializing in pipeline construction (Rohrleitungsbau) for district heating, gas, water, and pressure pipelines, supported by earthwork (Tiefbau), cable conduit installation (Kabelleitungsbau), plant construction (Anlagenbau), residential connections (Hausanschluss), and network planning and BIM documentation. The company employs trenchless methods — HDD horizontal directional drilling, suction excavation, and pipe jacking — to install or renew pipelines under roads, railways, waterways, and ecologically sensitive areas without surface excavation. Services are delivered through seven regional branches across northern Germany and North Rhine-Westphalia, serving municipal utilities, energy companies, and telecommunications providers.

Product overview

BHK Tief- und Rohrbau GmbH & Co. KG is a construction services company offering a comprehensive portfolio of underground infrastructure services from seven locations across northern Germany. The company's core offering centers on Rohrleitungsbau (pipeline construction) for district heating, gas, water, and pressure pipelines, supported by foundational Tiefbau (earthwork) services. The service portfolio extends through specialized trenchless technologies including Horizontalbohrungen (HDD drilling), Saugbaggern (suction excavation), and Schutzrohrpressungen (pipe jacking), complemented by Kabelleitungsbau (cable conduit installation) and Anlagenbau (plant construction) for gas, water, and district heating connections. Supporting services include Netzplanung und Dokumentation (network planning and documentation) with district heating monitoring capabilities, and Hausanschluss (residential connections) for multi-utility building connections. The company operates as part of the Seier Gruppe, a family-owned infrastructure construction group with over 100 years of history.

Broad incumbents

• Max Bögl Stiftung & Co. KG: Diversified German construction group with civil engineering, infrastructure, and energy-related construction capabilities. Overlaps with BHK on trenchless and pipeline work, though across a much wider portfolio.
• Goldbeck GmbH: Large German construction services firm with Tiefbau and infrastructure capabilities, though with broader building construction focus. Overlaps with BHK on utility civil engineering and turnkey infrastructure delivery.
• STRABAG AG: European construction incumbent with substantial pipeline, Tiefbau, and trenchless infrastructure operations across Germany. Competes with BHK for municipal tenders and has significantly greater scale.

Others

• TRACTO-TECHNIK GmbH & Co. KG: German manufacturer of trenchless installation equipment (HDD rigs, Grundomat moles, pipe ramming tools). Comparable to BHK only as an enabling technology supplier rather than a direct competitor — BHK is a downstream user of similar trenchless tools.
