Marti Group

What Marti Group does

Marti Group is a Swiss family-owned construction conglomerate founded in 1922 in Bern, Switzerland, and currently headquartered in Moosseedorf. The group operates through a federative structure of more than 80 autonomous subsidiary companies employing over 6,000 specialists, and delivers complex infrastructure and real estate projects as a total and general contractor. Its core competencies span four divisions: Construction (road construction, tunneling/underground structures, civil engineering, hydraulic engineering, high-rise construction, injection and waterproofing, flooring technology), Environmental Engineering (recycling, water treatment, contaminated site remediation, construction materials production, transport and disposal logistics), Technology (conveyor technology, electrical engineering, building technology, and custom plants and machines), and General Contracting (project development, portfolio analysis, overall performance competitions). Marti has built and operates specialized proprietary equipment including custom tunnel boring machines (for example, a 128m TBM with 12.39m diameter for the Gotthard Second Tube), a 12km purpose-built conveyor belt network, monorail tunnel transport systems, the ASTRA-Bridge mobile highway bridge, and a lake bed sediment removal system rated for 30m+ depths. Revenue is generated primarily through project-based construction contracts, general contracting fees, materials sales (aggregates, asphalt, concrete from Walliswil and Lätti facilities), and managed technology services including conveyor and electrical infrastructure operation and maintenance. Notable landmark projects include the Gotthard Road Tunnel Second Tube, the Lötschberg summit tunnel ballastless track replacement, the RBS underground railway station in Bern, the 205m Roche Tower II (Switzerland's tallest building), CERN, the Primetower, and the Sihl Valley flood relief tunnel capable of moving 330,000 liters per second. The group serves both Swiss public infrastructure authorities (ASTRA, BLS, RBS, ewz) and private clients (IOC, Felix Platter Hospital, Ritom SA, Roche), with international operations in Germany, Austria, Canada, Norway, and China (Hong Kong and Zhongshan City offices).
