KIENER Bau AG

What KIENER Bau AG does

KIENER Bau AG is a Swiss regional construction company founded in 1954 and headquartered in Baldegg (Canton of Lucerne), operating across the Seetal region and adjacent cantons including Luzern, Zürich, Zug, Sempach, Sursee, Muri, Aargau, and Lenzburg. The company provides four integrated service lines: Neubau (new construction of single-family homes, multi-family residences, residential developments, and complex industrial buildings), Gipserarbeiten (plastering, exterior thermal insulation, dry construction, and customer plasterwork), Kernbohrung + Fräsen (specialized concrete core drilling from 1–100cm diameter plus wet and dry concrete milling), and Umbau + Erneuerung (renovation, waterproofing and injection works, structural and earthquake reinforcement, bonded reinforcements, concrete repairs, and small demolition works). All services are delivered on-site by direct field teams rather than through subcontractors or partners.

The company employs approximately 80 staff, including Bauführer (construction supervisors), Poliere (foremen), Vorarbeiter (leading workers), workers, and apprentices, with continuous professional development cited as a stated practice. The business model is project-based: each engagement is individually quoted based on scope, complexity, and specifications, with no publicly disclosed pricing and multi-year contract billing cadence observed. Customers are segmented horizontally into private builders, public builders (municipal and government entities), and industrial clients. Two reference customers are publicly named — Leuenberger Architekten AG and Seerose Spa Meisterschwanden — though neither represents a disclosed recurring revenue anchor.

KIENER Bau AG is a privately held corporation domiciled in Switzerland, with no public ticker, no disclosed funding history, and no subsidiaries. It is a member of the 'Ihr Baumeister' master builder group, which provides collective marketing presence and shared digital channels, and it holds SGS-certified quality management certification. The go-to-market motion is enterprise field sales: direct customer contact via phone (041 910 18 58), email contact form, and on-site consultation, supplemented by a corporate website, Google Business Profile, Instagram (@kiener_bau_ag), and TikTok (@ihr_baumeister). Revenue is not publicly disclosed; the firm does not appear to have raised outside capital, executed M&A, or made public strategic announcements beyond workforce retirements and ongoing recruitment activity.

Closely comparable as a multi-disciplinary Swiss Baumeister serving residential, commercial and industrial clients with both new-build and renovation capabilities.

Comparable as a Swiss general contractor serving both private and public builders, though much larger and active nationwide rather than regionally.
