Ernst Frey AG

What Ernst Frey AG does

Ernst Frey AG is a privately held, family-owned Swiss construction company (Bauunternehmen) founded in 1912 and headquartered in Kaiseraugst near Basel, operating across five integrated divisions: Strassen- und Tiefbau (road and civil engineering), Hochbau (structural construction), Umbau und Sanierung Plus (renovation and hazardous material remediation), Baustoffe Rinau (concrete and gravel production), and ef kompakt (comprehensive project management and real estate services). The firm employs 316 staff plus 15 apprentices across locations in Kaiseraugst, Frick, Basel, and Bad Säckingen (Germany), with a workforce representing 21 nationalities and 113 years of operating history. It serves two primary customer segments: business customers in commerce, industry, and the public sector (via construction services and materials supply), and private customers seeking renovation or new-build support (via Umbau und Sanierung Plus and ef kompakt).

The business model is diversified across revenue streams including construction services (professional services on multi-year contract terms), construction materials production and sales (pay-as-you-go unit pricing for concrete and recycling products), real estate development (one-time project sales such as Römerpark II's 106 apartments), and client representation and property management. Distribution is direct to customers without intermediaries, anchored on personal consultation, in-house production capacity via the Baustoffe Rinau plant, gravel pits, recycling operations (REWAG), and asphalt production (Belagswerk Rinau AG), plus the cross-border materials subsidiary ORB Baustoffe GmbH in Germany. The company holds multiple industry certifications (IQNet, SQS, FSKB, SUVA, SUGB-ASMP, VKB) supporting public-sector bidding and operates as a one-stop construction provider in the Basel/Northwest Switzerland region.

Notably, the company combines vertical integration across the construction value chain (materials extraction, concrete production, recycling, asphalt, real estate) with general contracting, allowing cross-divisional project execution such as the Römerpark II development (84,000 tons excavation, 15,000 m³ concrete) completed 20 days ahead of schedule, and the joint venture with Häring for 7 single-family homes in Biel-Benken. Pricing is project-by-project quotation, with the largest disclosed project at CHF 400,000 (Rheinfelden Kirchgasse street restoration) alongside the substantial Römerpark II residential development.
