HEW

What HEW does

HEW AG Bauunternehmung is a Swiss construction company headquartered in Domat/Ems in the canton of Graubünden, founded in 1938 by Conrad Hew. Operating across six regional locations (Chur, Domat/Ems, Davos, Klosters, Scuol, Zernez), the company delivers integrated construction services through five core divisions: Tief- & Strassenbau (civil engineering and road construction), Hochbau (building construction for residential, commercial, industrial and public clients), Schnellbau (rapid renovation services for private homeowners), Bohren & Trennen (precision concrete drilling, cutting, milling and sawing), and Immobilien (real estate development and sales of turnkey residential properties such as Seglias in Cunter and Scalottasblick in Cazis). The group also operates two wholly-owned subsidiaries: Kieswerk Safiental AG (gravel and quarry operations, founded 2012) and Zehnder Spezialbau AG (trenchless construction, acquired 2013).

The underlying technology stack is conventional construction equipment augmented by modern precision tooling for concrete drilling, cutting, and milling work that delivers millimeter-accurate results. HEW holds ISO 9001 quality certification (since 1997) and ISO 14001 environmental certification (since 2024), both issued by SQS/IQNET. With approximately 200 qualified employees plus 8 apprentices in four trades, HEW combines large-project civil and building construction capabilities with agile small-team renovation services through its Schnellbau offering.

HEW's revenue model is project-based and quote-driven across both public-sector tenders and private/commercial contracts, with individual projects ranging from CHF 250,000 to over CHF 9.6 million. The company is sales-led, reaching customers through personal consultation at regional offices, referrals, and local brand presence in Graubünden. In 2023, the founding Roth family transferred majority ownership to three management members (including CEO Marcel Kunfermann), completing a generational succession while maintaining family board representation. Revenue is not publicly disclosed, and the company remains privately held.

Scale indicators5 records

Recent moves8 records

Expansion highlights6 records

Broad incumbents

• Implenia AG: Switzerland's largest construction and real estate services group, offering general contracting, civil engineering, and real estate development. Directly comparable because Implenia previously operated HEW's home canton (Graubünden) and the 2021 closure of its Graubünden branches was a direct catalyst for HEW's expansion.
• Walo Bertschinger AG: Major Swiss general contractor specializing in civil engineering, road construction, and building construction. Comparable to HEW across both Tiefbau/Strassenbau and Hochbau divisions, though at a larger national scale.
• STRABAG AG (Switzerland): Swiss subsidiary of European construction giant STRABAG SE, active in civil engineering, road construction, and building construction. Comparable to HEW in Tiefbau/Strassenbau, though operating at significantly larger scale and international backing.

Others

• Holcim (Schweiz) AG: Swiss arm of global building materials giant, supplying aggregates, ready-mix concrete, and asphalt. Comparable to HEW's Kieswerk Safiental AG subsidiary and to HEW's material supply chain rather than its contracting operations.

Direct peers

• KIBAG Bauleistungen AG: Swiss construction group offering civil engineering, road construction, building construction, and gravel/quarry operations. Closely comparable to HEW because it combines Tiefbau/Strassenbau/Hochbau with vertical material supply, mirroring HEW's Kieswerk Safiental integration.
• Anliker AG: Swiss construction and real estate development group offering general contracting, civil engineering, and property development. Directly comparable to HEW as a multi-service Swiss contractor with integrated real estate development operations.
• Mettler Prader AG: Swiss construction company operating across Hochbau, Tiefbau, and civil engineering with multiple regional offices. Comparable to HEW in regional branch model, scope of services, and target customer mix (private + public sector).
• Toldo Bauunternehmung AG: Regional Swiss construction company focused on Hochbau, Tiefbau, and customer renovation services. Comparable to HEW in service mix and target customer segments including private homeowners and commercial clients.
• Frutiger AG: Swiss general contractor with multi-decade history offering Hochbau, Tiefbau, Strassenbau, and Immobilien services across multiple cantons. Comparable to HEW as a multi-disciplinary Swiss construction company of similar mid-market size and integrated service model.

Regional players

• Casada AG: Graubünden-based construction company serving the Engadin and surrounding Alpine regions. Most direct geographic peer to HEW, operating in overlapping Alpine market areas with similar civil and building construction offerings.
