What Stam&Co Infratechniek does

Stam & Co Infratechniek B.V. is a Dutch multidisciplinary underground infrastructure contractor founded in 1951, headquartered at Diamantweg 10 in Alkmaar, and operating as a wholly-owned subsidiary of Van Gelder Groep since December 2021. The company designs, engineers, constructs, and maintains underground cable and pipeline systems across five interlocking disciplines: Gas, Water, Elektra (electricity), Telecom/Fiber, and Combi (combined multi-utility installation). Supporting services include Rail infrastructure (ProRail switch heating, CCTV, telecom), EV charging stations, residential and commercial Connections (executed as subcontractor to network operators via the mijnaansluiting.nl portal), Data Cabling, Gas pipeline remediation/decommissioning, and Digitaal Inmeten GPS surveying for Kadaster/WION compliance.

The technical backbone combines in-house multidisciplinary engineering, specialized field crews, and GPS-guided directional drilling (gestuurde boring) for trenchless cable and pipe installation under roads, railways, waterways, and contaminated ground. Internal safety governance rests on the STAM methodology (Samenwerken aan veiligheid / Tijd nemen voor veiligheid / Aanspreken op onveiligheid / Melden onveilige situaties) coupled with the VeiligWerkApp real-time safety reporting tool. Project transparency is delivered through a digital visualization partnership with The People Group - Scanopy, allowing stakeholders to monitor project progress on map materials. Certifications cover ISO 9001, ISO 27001, VCA** (highest), CKB, BRL 7000 (protocols 7001/7004/7005), CO2 Performance Ladder Level 5 (highest), and Safety Culture Ladder Level 4.

The business model is project-based: revenue is generated through tenders and direct contracts with Dutch network operators (Liander, Stedin, Alliander, PWN, Waternet), government agencies (ProRail, RDW, municipalities), public transport operators (GVB), and construction developers (CINH consortium), plus subcontracted residential connection work via the national mijnaansluiting.nl portal. Primary operations are concentrated in North Holland, with project offices in Amsterdam and Nieuwegein supporting nationwide coverage. The company employs approximately 140 technical, engineering, project management, and administrative staff.

Core offering

Stam & Co Infratechniek B.V. is a Dutch contractor that designs, engineers, builds, and maintains underground cable and pipeline infrastructure for utility networks. Its portfolio covers low- and medium-voltage electricity, low- and high-pressure gas, drinking water and sewage systems, copper and fiber-optic telecom, EV charging, and rail infrastructure, including combined multi-utility ("Combi") installations delivered by in-house engineering and field crews. Services span preliminary design, permitting, route planning, digital surveying, directional drilling, construction, and final commissioning for network operators, municipalities, and construction developers.

Product overview

Stam & Co is a multidisciplinary underground infrastructure contractor offering a unified portfolio of construction and engineering services. The core offering spans five interconnected service lines: Gas, Water, Elektra (electricity), Engineering, and Combi (combined utility installation). These are delivered by the company's own engineers, project managers, and field crews and are supported by specialized services including Telecom/Fiber, Rail infrastructure, residential Connections, Data Cabling, Gas Remediation, and Digital Surveying. The Combi service acts as the integrating mechanism—coordinating simultaneous installation of multiple utilities (electricity, gas, water, telecom, cable) in a single construction pass—which requires tight project management from the Engineering team and benefits from the company's own survey and documentation capabilities.

Direct peers

• Van Gelder Kabel-, Leiding- en Montagewerken: Sister company of Stam & Co within Van Gelder Groep, operating in the same underground cable, pipeline, and installation market across the Netherlands. Most directly comparable peer because of overlapping service portfolio, customer base (network operators), and shared group ownership.
• A. Hak: Dutch specialist contractor for underground and above-ground pipelines, cables, and industrial infrastructure. Directly comparable in service mix (gas, water, electricity, telecom) and customer base of Dutch network operators and industrial clients.
• Visser & Smit Hanab: Dutch utility and pipeline contractor (part of VolkerWessels) executing underground gas, water, district heating, and cable infrastructure. Comparable on multi-utility underground construction and Dutch utility customer base.
• Mourik Infra: Dutch family-owned contractor group with infrastructure division executing pipeline, cable, and industrial installations for utilities and industry. Comparable multi-utility underground scope and family-business heritage.
• Homij (Technical Installations): Dutch technical installation contractor (VolkerWessels) executing electrical, instrumentation, and utility infrastructure. Comparable on electrical infrastructure and rail-side installations for Dutch clients.

Broad incumbents

• Heijmans Infra: Major Dutch construction group with a substantial infrastructure division covering energy networks, mobility, and civil works. Broader incumbent in the same Dutch infrastructure market with overlapping underground utility capabilities.
• BAM Infra Nederland: Largest Dutch heavy civil contractor (Royal BAM Group), executing large-scale utility, energy, and rail infrastructure. Overlaps with Stam & Co on cable/pipeline and rail (ProRail) projects but operates at significantly larger scale across multiple disciplines.
• Strukton Civiel: Dutch contractor (Strukton group) active in civil infrastructure including cable and pipeline works for utilities and rail. Comparable on underground utility scope and ProRail framework participation, but with broader infrastructure portfolio.
• SPIE Nederland: Subsidiary of French SPIE group providing technical installations and energy infrastructure services in the Netherlands, including electrical distribution and EV charging. Comparable on electrical networks and EV charging infrastructure installation.

Emerging players

• Klever Boren: Specialized Dutch directional drilling contractor engaged as a subcontractor by Stam & Co on complex bores. Comparable niche capability for trenchless crossings, though operating at a smaller scale as a specialist subcontractor.
