Engineering Scope & Project Story
A convenient pedestrian tunnel directly connecting the RAMS Beyond complex in Maslak to the İTÜ-Ayazağa station on the M2 Yenikapı–Hacıosman metro line beneath busy Büyükdere Avenue, without interrupting road or pedestrian traffic. NATM excavation and jet-grout ground consolidation protect underground utilities with millimetre precision. The tunnel includes full climate control, moving walkways and accessible routes.
Advanced Safety & Occupational Health
A zero-accident policy aligned with ISO 45001 and continuous gas-monitoring systems.
Modern Technology
Laser-guided TBM steering, hydraulic injection and high-strength reinforced-concrete solutions.
Environment & Sustainability
Zero-settlement excavation methods that protect groundwater conditions and the urban fabric.
