APT Ingenieure GmbH

What APT Ingenieure GmbH does

APT Ingenieure GmbH is a Zürich-based structural engineering firm (Atelier für Planung und Tragkonstruktion) founded in 1989 by Andreas Lutz. It provides full-scope structural engineering services — feasibility studies, Vorprojekt/Bauprojekt/Ausführungsprojekt planning, tendering, construction supervision, and expert opinions — for new builds, renovations, restorations, civil engineering, and bridge projects. Core technical work spans reinforced concrete (Stahlbeton), steel (Stahl), timber (Holz), and masonry (Mauerwerk) load-bearing systems, with specialized capabilities in self-compacting concrete (SCC), CFK/steel laminate reinforcement, seismic safety assessment and strengthening, excavation support, foundations, and BIM-based planning. The firm operates with a 24-person team organized in a flat hierarchy where project managers run projects end-to-end.

The client base is concentrated in the greater Zürich region but extends across northern and central Switzerland, comprising public institutions (ETH Zürich, Stadt Zürich, Kanton Zürich, SBB, BBL), housing cooperatives (Baugenossenschaft Milchbuck), private developers, and architectural firms that engage APT as a competition partner. Notable reference projects include the Swiss National Museum reconstruction (CHF 165M), ETH HIF renovation and extension (CHF 150M), Bildungszentrum Uster (CHF 120M), and Wohnsiedlung Herzogenmühle (CHF 110M). The firm has secured first-rank finishes in multiple 2025–2026 architectural competitions.

Revenue is generated entirely through project-based professional services fees, with no subscription or recurring model. Pricing is determined per project based on scope, complexity, and construction value. The firm acquired ISO 9001 certification in 2001 and operates as a privately held Swiss GmbH. Ownership transferred from founder Andreas Lutz to long-term employees Ergin Telli and Tom Richter through a succession process begun in 2011 and completed in early 2014.

Direct peers

• TBF + Partner AG: Swiss engineering firm with structural, civil, and geotechnical expertise. Comparable to APT in technical depth and project mix, particularly in foundation and civil engineering works.
• WaltGalmarini AG: Zurich-based structural engineering consultancy with a similar portfolio of high-rise, bridge, and public infrastructure projects across Switzerland. Best-in-class peer for APT given the shared focus on complex structural design and Zurich-area public clients.
• Conzett Bronzini Partner AG: Chur/Zurich-based structural engineering office with a recognized profile in bridge engineering and historic restoration. Comparable to APT in size, approach, and competition-track-record positioning within the Swiss Structural engineering market.
• Schnetzer Puskas Ingenieure AG: Swiss structural engineering firm with comparable scope in building and bridge engineering, including timber, concrete, and steel. Directly competes with APT for architectural competitions and public tenders in the German-speaking Swiss market.
• Lüchinger+Meyer Bauingenieure AG: Zurich-based structural engineering consultancy with strong credentials in complex high-rise and cultural building projects. Overlaps with APT on flagship cultural and institutional commissions in the Zurich market.
• Dr. Deuring + Oehninger AG: Winterthur-based structural engineering firm with similar size and project range, including masonry, timber, and concrete works. Direct regional competitor for housing cooperative and SME developer projects.

Broad incumbents

• WSP Suisse AG: Global engineering consultancy with a significant Swiss presence, including structural engineering for large public and private projects. Competes with APT for major mandates like the Wohnsiedlung Herzogenmühle development.
• Basler & Hofmann AG: Large Swiss engineering consultancy offering structural, infrastructure, and environmental services. Overlaps with APT on structural engineering but competes as a much broader, multi-disciplinary incumbent with institutional scale.

Regional players

• Synaxis AG (formerly Suter & Suter): Swiss structural engineering firm with a track record in public and private building projects. Comparable in service offering and project type, with strong presence in western Switzerland.

Emerging players

• Holzbauingenieure (e.g., Pirmin Jung Ingenieure AG): Swiss engineering firm specializing in timber and hybrid timber construction, increasingly relevant for hybrid projects like the Schulareal Uetikon am See. Partial overlap with APT on mass timber and hybrid building structures.
