What Large General Contractor does

Gross Generalunternehmung AG is a privately held Swiss general and total contractor (Generalunternehmer/Totalunternehmer) founded in 1961 and headquartered in Brugg, Canton Aargau, with a regional office in Wallisellen in the greater Zürich area. The firm delivers complex construction projects across residential, commercial, educational, healthcare, research, sports, and public infrastructure segments, operating as either a general contractor (coordinating subcontractors under its own management) or a total contractor (assuming full single-point responsibility for planning, coordination, and delivery). Contract values per project typically range from CHF 15 million to over CHF 100 million, sourced through competitive bidding, total performance competitions (Gesamtleistungswettbewerb), and direct commissions from property owners, developers, and public entities.

The company's service portfolio is organized around two main pillars: Entwickeln (development services including site analysis, market perspective evaluation, economic planning, and project development from individual buildings to district-level concepts) and Realisieren (construction execution covering general contracting, turnkey delivery, renovation, and revitalization). Project execution is anchored in Building Information Modeling (BIM), with the firm acting as BIM Manager and BIM Coordinator on projects, producing BIM implementation plans (BAP), applying 3D modeling for clash detection and quantity takeoffs, and coordinating all stakeholders through a digitally networked planning process. Notable projects include the University of Bern (CHF 100M+ volume, won via total performance competition in 2014), Aeschbach-Areal Aarau with Mobimo (CHF 52.8M, groundbreaking February 2024), Steinhof Würenlos residential (CHF 48.5M), Schule Integra Wallisellen (CHF 27.2M), and Schulanlage Surbaum Reinach (completed July 2024).

Gross Generalunternehmung AG generates revenue on a project-by-project basis under a sales-led, bid-driven go-to-market model. Pricing is quote-based and not publicly disclosed; contracts are won through competitive tenders, total performance competitions, or direct negotiation. The customer base spans Swiss municipalities and school districts (public sector) and institutional real estate investors and developers (Mobimo, Suva, RehaClinic, Education First, Integra Immobilien AG). Headcount is reported in the 51-100 range, consistent with a mid-sized specialist contractor. The firm is incorporated as a Swiss Aktiengesellschaft (AG), privately held with no disclosed parent company, institutional investors, or external funding, and operates entirely within Switzerland with no disclosed international expansion plans.
