What Gruner SA does

Gruner SA, operating as part of the Gruner AG group, is an independent Swiss engineering consultancy founded in 1862 and headquartered in Basel. The firm delivers comprehensive engineering design, planning, and project management services across three sectors — building construction, infrastructure, and energy — for both private and public sector clients throughout all project phases, from strategic planning through construction, commissioning, and ongoing asset management. With 1,100+ employees distributed across 30+ offices in Switzerland, Germany, Austria, Serbia, Georgia, Turkey, Tajikistan, and the Philippines, Gruner operates as a multi-disciplinary general planner, combining structural design, geotechnical engineering, building services, fire protection, environmental, safety, and spatial planning expertise under one roof.

The company's technology portfolio is anchored by its proprietary BIIM (Better Information and Innovation Management) concept, which integrates BIM modelling (3D through 5D), Scan2BIM reality capture, Digital Twins, BIM2Field, and scripting/automation-driven parametric design. Specialized technical capabilities include Finite Element Modelling for dam engineering using DIANA FEA, CFD-based fire simulations, and the sustbl cloud-based SaaS platform for municipal sustainability management. Gruner also operates buildingSMART-certified BIM training programs and an expanding suite of fire safety courses.

Revenue is generated primarily through professional services fees from engineering design, general planning, and construction management mandates, supplemented by BIM consultancy and training fees (e.g., CHF 7,500 per group BIM foundation course), recurring SaaS revenue from sustbl, and digital marketplace transactions via the Gruner ReUse eShop. Go-to-market is direct enterprise and government field sales, leveraging the regional office network for proximity-based project delivery, with brand reinforcement through international conference participation and a multilingual digital presence. The firm remains a privately held, family-owned business without disclosed parent ownership.
