Keller Bauingenieure Ag

What Keller Bauingenieure Ag does

Keller Bauingenieure AG is a privately held Swiss structural and civil engineering firm headquartered in Rheinfelden, Canton Aargau. Founded in 2019 by Steven Keller as a spin-off from Fischer + Röthenmund AG, the firm operates with a team of approximately 16 specialists and serves clients across the Fricktal region and Northwestern Switzerland, with occasional cross-border projects into southern Germany. The company organizes its work around two core divisions — Hochbau (structural engineering for buildings) and Tiefbau (civil infrastructure) — and supplements these with a portfolio of specialist services including seismic safety assessment, foundation engineering, flood protection, renovation and repair, vibration measurement, crack documentation, and independent structural review (Prüfstatik).

The firm's core technology stack centers on 3D structural analysis and CAD systems (AxisVM, BauPlus, Cadwork, Cedrus/Larix, Dlubal RSTAB, Frilo, Strakon, and others) used for static calculations in concrete, steel, and timber, with manual plausibility verification and a strict four-eyes quality principle. A distinctive asset is the engineering archive consolidating structural plans and calculations from 11 predecessor firms dating back to 1944, which provides a regional reference baseline for renovation and extension work. The firm also holds and operates the Deponie Seckenberg landfill in Frick on behalf of the municipal waste association GAOF, processing approximately 20,000 tonnes of material annually.

Keller Bauingenieure AG generates revenue through project-based professional services fees — including structural calculations, construction planning, construction supervision, and specialist engineering opinions — billed individually per project scope and complexity. The go-to-market model relies on direct enterprise relationships, architect referrals, and repeat clients, with partnerships spanning architectural firms (Hansjörg Steck, Lenzin Partner), construction companies (Anliker, S2 Bauleitung), environmental engineers (CSD Ingenieure), and steel fabricators. Customer segments include residential developers, commercial and industrial enterprises, public sector bodies, and utilities, with project examples spanning the AEW Wärmezentrale, Kraftwerk Ryburg-Schwörstadt, Coop Schoggi production facility, Westfalen gas supply expansion, and various municipal flood protection works.
