Sustainability Focus HOLINGER has a long-standing specialization in water cycle-related engineering and sustainability across wastewater, urban drainage, environment & sustainability, and water supply, indicating opportunities for projects tied to water management optimization, green infrastructure, and municipal sustainability programs.

Multi-Location Scale With over 30 locations and 700+ staff, HOLINGER demonstrates broad geographic reach and capacity to handle large, multi-site projects, suggesting potential for national or regional contracts, shared services, and scalable solutions across Switzerland, Germany, and Luxembourg.

Digital & Tech Tools Adoption of diverse tech stack (ArcGIS, AutoCAD, M365, Miro, iCIMS) indicates a modern, data-driven delivery approach and openness to software-enabled workflows, creating opportunities to offer advanced GIS, digital planning, and collaboration tools or integrated project platforms.

Project Volume Active engagement in ~4,500 projects annually signals a strong project pipeline and potential for repeat business in core domains, including hydraulic engineering, energy, and construction, as well as opportunities for ongoing maintenance, monitoring, and optimization contracts.

Strategic Partners Recent collaboration with regional water management authorities and partner firms for stream development concepts demonstrates propensity for alliance-led projects and public sector opportunities, suggesting a pathway for bundled solutions with complementary firms or advisory services.
