Tunnel Superintendent

The MTAs Second Avenue Subway project is a $7.7B expansion that will extend the Q Line from 96th Street into East Harlem, adding three new ADA-accessible stations at 106th, 116th, and 125th Streets. This long-awaited project will restore rapid transit access to a community underserved for decades, ease overcrowding on the Lexington Avenue line, and cut commute timesdelivering a transformative impact for East Harlem residents and the city as a whole. This position will support the $2 billion design-build contract for Phase 2, which includes two tunnels that will enable the development of two new subway stations in New York. Led by Connect Plus Partners, a joint venture between FCC Construction and Halmar International, the project brings together extensive experience in large-scale infrastructure, complex tunneling, and urban transit construction. Position Summary The Tunnel Superintendent is responsible for supervising daily tunneling operations, including excavation, ground support, waterproofing, and final lining, ensuring that all work is executed safely, efficiently, and in accordance with design specifications and the project schedule. This field-based leadership role involves direct coordination with crews, subcontractors, surveyors, engineers, and support personnel in challenging underground conditions. The Tunnel Superintendent is assigned to TBM, SEM, or conventional tunnel excavation zones and plays a central role in delivering high-quality tunnel works on schedule and within budget. The Tunnel Superintendents key responsibilities are: * Supervise and coordinate all field activities related to tunnel excavation, initial support, waterproofing, and final lining. * Manage daily construction operations for TBM, SEM, or conventional tunneling methods, ensuring alignment with project requirements. * Direct crews and subcontractors in tasks such as mucking, ventilation setup, ring installation, shotcrete application, rock bolting, and membrane installation. * Monitor ground conditions and interface with geotechnical personnel to adapt excavation and support techniques as needed. * Enforce strict adherence to safety protocols and lead daily toolbox talks, field briefings, and safety inspections. * Coordinate site logistics for material handling, utility relocations, muck disposal, and equipment operations in confined tunnel environments. * Maintain accurate daily reports, shift logs, and quantity tracking; input progress data into project management systems. * Interface with survey, quality control, and engineering teams to verify work alignment, tolerances, and compliance with design drawings. * Support resolution of constructability issues, field clashes, or deviations from the design. * Participate in shift handovers, workforce allocation planning, and schedule coordination with other project areas. * Ensure timely installation and backfilling of instrumentation as required by the monitoring program. * Collaborate with the Tunnel Construction Manager and Tunnel General Manager to address productivity goals, staffing needs, and corrective actions. * Oversee tunnel safety systems including ventilation, gas detection, and emergency egress routes. * Provide direct supervision of the excavation and support of mined tunnel excavations. * Be physically present in the tunnel during each shift to lead tunneling activities. * Responsible for executing mined tunnel excavation, installation of initial support systems, shotcrete application, and grouting operations to ensure safety, quality, and timely completion. * Implement remedial or contingency measures promptly when ground loss, water inflow, or instability occurs or is anticipated. * Ensure compliance with the Tunnel Work Plan and initiate actions when ground movement Threshold Limit Values (TLVs) are approached or exceeded, and when ground loss or instability or water inflow occurs or appears likely
