• WaltGalmarini AG: Zurich-based structural engineering firm serving residential, commercial, and infrastructure clients in Switzerland — comparable to Kielholz on multi-sector structural engineering scope and Swiss-market focus.
• Bänziger Partner AG: Swiss structural engineering firm covering building, infrastructure, and seismic projects — comparable to Kielholz across the same core structural-engineering and seismic service lines.
• Henauer Gugler AG: Swiss engineering consultancy delivering structural design, BIM, and seismic analysis — directly overlapping Kielholz's structural, BIM, and Erdbebenanalysen service stack.
• Frei + Saarinen AG: Swiss structural engineering consultancy active in Hochbau and special constructions — comparable to Kielholz's structural engineering focus and Swiss project profile.
• dsp Ingenieure + Planer AG: Swiss engineering and planning firm with structural, civil, and infrastructure services — comparable to Kielholz on multi-disciplinary engineering delivery for Swiss clients.
• Lüchinger + Meyer Bauingenieure AG: Swiss structural and civil engineering consultancy specialising in Hochbau, Stahlbau, and complex engineering services — directly comparable in service mix and project type to Kielholz's core Hochbau/Stahlbau offerings.

Emerging players
