What sustra does

Sustra Tiefbau + Strassen AG is a privately held Swiss construction company founded in 1956 and headquartered in Sursee, Canton Lucerne. It delivers an integrated portfolio of civil engineering (Tiefbau), road construction (Strassenbau), pavement construction (Belagsbau), and noise barrier (Lärmschutzwände) services, supported by an in-house recycling facility that produces SÜGB-certified recycled aggregates from concrete and asphalt demolition waste. Its customer base consists primarily of Swiss public-sector buyers — federal (ASTRA), cantonal road authorities (notably Canton Lucerne), and municipalities (Cham-Hünenberg, Dagmersellen and others) — with a secondary segment of private developers; revenue is generated through public tenders and direct contracts, often via ARGE joint ventures with peer firms for large infrastructure works.

The company's operating model is asset-heavy and project-based. Sustra operates a modern heavy equipment fleet — over 40 hydraulic excavators, 5 asphalt pavers, more than 20 vibratory and pneumatic rollers, and 12 trucks — together with a 200 tonnes/hour GIPO R 131 C Giga Special crusher and mobile crushing capability acquired in 1988. Four regional branches (Sursee HQ, Schöftland, Rotkreuz, Olten) provide geographic coverage across cantons Lucerne, Aargau, Zug, Solothurn and Zurich. Certifications — ISO 9001:2015 since 1997, ISO 14001:2015 since 2024, and SÜGB recycled material certification since 2017 — are central to its tender prequalification.

Sustra has no external investors or public shareholders; ownership remains within a private corporate structure, and no funding rounds are disclosed. Its go-to-market is direct sales-led: contracts are won through public tenders or direct negotiation, and larger projects are executed as lead contractor or as ARGE joint-venture partner. The firm runs an active in-house apprenticeship program for Strassenbauer and Baumaschinenmechaniker at its Sursee workshop, addressing labor scarcity in the Swiss construction trades. Notable project references include a 100+ million CHF pipeline contract (2001, ARGE Surental), the N14 Buchrain-Rütihof highway (39,985 tonnes of asphalt over 8.2 km), the Umfahrung Cham-Hünenberg West urban infrastructure, the K34 Ruswil-Wolhusen cantonal road, and the K47 Oberkirch bridge demolition using a 650-tonne crane.
