Wirz AG Bauunternehmung

What Wirz AG Bauunternehmung does

Wirz AG Bauunternehmung is a Bern-based, family-owned general construction contractor (Baumeister) founded in 1912 that delivers Baumeisterarbeiten — concrete, masonry, and structural works — for residential, commercial, industrial, and heritage projects across the Bern and Greater Bern region (extending into neighboring cantons such as Fribourg). The company operates as part of the broader Wirz Unternehmungen group, which integrates six wholly-owned specialized subsidiaries covering timber construction (Wirz Holzbau AG), hazardous-material remediation (Wirz AG Schadstoffsanierung), building technology and coatings (Wirz Bautechnik), historic restoration (Wirz Restauratoren), HVAC and sanitation (König Haustechnik AG), and pipe and canal systems (Pro Rohr AG), enabling single-source delivery of complex, multi-trade projects including heritage-protected assets.

The underlying technology is traditional construction craft — in-situ reinforced concrete (Ortbeton), prefabricated timber elements, civil engineering works, and heritage-conservation techniques — supported by an owned crane fleet and ISO 9001:2015-certified quality management (renewed 2025-2028). Notable execution credentials include work on the Swiss National Bank headquarters at Bundesplatz 1, the UNESCO-listed Kultur Casino Bern (1909), PSP Swiss Property's Bärenplatz heritage buildings, the federal Verwaltungszentrum Guisanplatz, the Spital Sonnenhof operating-theater build-out, and the ongoing ARGE role on SBB's Bahnhof Bern public-facilities expansion.

The business model is project-based professional services: revenue is earned through prime-contractor Baumeister mandates, secured via competitive public tendering and direct negotiation with private developers. Anchor client types include federal agencies (SBB, BBL), cantonal/municipal institutions, Swiss pension funds, listed real-estate owners (PSP Swiss Property), retail/logistics operators (Genossenschaft Migros Aare), and housing cooperatives (Baugenossenschaft Brünnen-Eichholz). Pricing is project-specific and not publicly disclosed; the firm operates a sales-led, direct-bid go-to-market with no SaaS, subscription, or recurring-revenue component.
