What BuildtoImpact does

BuildtoImpact (legal name: Group 5 Consulting Engineers B.V.) is a The Hague-based consultancy founded in 1988 and rebranded under its current trade name in 2018. The firm provides advisory services for sustainable construction and infrastructure projects, operating across two thematic tracks: a social transition track using participatory methods (value engineering, serious gaming, community action planning), and a raw materials transition track focused on circular construction and geopolymer concrete innovation. Its service portfolio spans project and program management, environment management, Value Engineering studies, circular construction advisory (covering circular design, second-life materials, material passports, circular financing, and circular procurement), and geopolymer concrete research and field testing.

The company's core technical differentiator is its geopolymer binder technology, an alternative binder system that replaces Ordinary Portland Cement in concrete production. The firm states this approach can reduce CO2 emissions by up to 90% relative to OPC-based concrete, and enables use of locally available raw materials including volcanic ashes, alternative sand qualities, and even local shells recovered from shell-bicycle-path maintenance on Ameland. R&D outputs include documented concrete recipes and a 2018 public field test led by team member Alexander van Leersum.

The business model is professional services / project-based consulting. Revenue derives from advisory and Value Engineering engagements with Dutch municipalities (named clients include Gemeente Rotterdam, Gemeente Ameland, and Gemeente Utrecht), construction contractors, and international NGOs/development institutions (World Bank Group, Cordaid, Dutch Red Cross, International Baccalaureate). Geographic footprint spans the Netherlands, broader Europe, Africa (notably Uganda), and Asia. Pricing is quote-based and not publicly disclosed. The team disclosed on the website consists of three members (Vera Kreuwels, Alexander van Leersum, Nida Siddiqui), indicating a boutique operating model. The firm is privately held with no disclosed institutional investors, no funding rounds, and no parent company.

Core offering

BuildtoImpact is a Dutch consultancy (legal name: Group 5 Consulting Engineers B.V.) providing project and program management, environment management, and Value Engineering advisory services for sustainable construction and infrastructure projects. The firm drives two parallel transitions: a social transition using participatory methods (value engineering, serious gaming, community action planning) and a raw materials transition focused on circular construction and geopolymer cementless concrete using locally available raw materials.

Product overview

Build to Impact is a consultancy firm offering advisory and consulting services for sustainable construction and infrastructure projects. The company operates as a unified service offering rather than a platform-plus-modules architecture. Their core portfolio centers on two transition areas: social transition (using participatory methods like value engineering, serious gaming, and community action planning) and raw materials transition (focused on circular construction and geopolymer concrete innovation). Key service offerings include project and program management, environment management, Value Engineering studies, circular construction advisory, and geopolymer concrete research and field testing. The company works with local governments, contractors, and NGOs on projects primarily in Europe, Africa, and Asia.

Direct peers

• Metabolic: Amsterdam-based sustainability consultancy advising governments, businesses, and NGOs on circular economy transitions including the built environment. Highly comparable boutique scale, Dutch base, and advisory focus on circular built environment.
• Circle Economy: Amsterdam-based impact organization that drives circular economy implementation across industries and publishes the Circularity Gap Report. Comparable mission, Dutch base, and consulting-style engagement model with governments.
• Drees & Sommer: German engineering consultancy with strong sustainability, life-cycle, and circular-construction practice serving European developers and governments. Comparable boutique-firm character and European base with overlapping circular-construction focus.
• Madaster: Dutch Registry-as-a-Service for material passports enabling circular construction; headquartered in the Netherlands. Comparable focus on enabling circular construction, but delivered through a software/SaaS platform rather than advisory services.
• Ecocem: Ireland/France-based low-carbon cement and concrete technology company developing alternative binders. Closely related technology direction addressing the same end-customer need for low-CO2 concrete.

Others

• Heidelberg Materials: One of the world’s largest cement and aggregate producers, actively developing low-CO2 binders and circular-construction materials (evoBuild, geocycle). Operates in the adjacent technology space as a major incumbent rather than comparable services.

Broad incumbents

• Arcadis: Global Dutch-headquartered engineering consultancy with sustainability, climate, and resilience practices spanning buildings, infrastructure, and cities. Overlaps significantly in sustainable built-environment advisory.
• Royal HaskoningDHV: Major Dutch engineering consultancy with a dedicated sustainability and circular-economy practice serving governments and developers. Larger and broader, but directly competes for circular-construction advisory mandates.
• Witteveen+Bos: Large Dutch engineering consultancy with established sustainability and circular-construction practices across infrastructure and the built environment. Comparable service area but at much larger scale and broader scope than BuildtoImpact.

Emerging players

• CarbonCure: Canadian company reducing concrete CO2 footprint through mineral CO2 sequestration during mixing. Comparable mission of decarbonizing concrete but with a different technological approach and broader commercial traction.
