From the reconstruction and replacement of transportation facilities within the country’s oldest infrastructure to the construction of new intermodal facilities, GM2’s structural engineers support the continued maintenance and growth of our infrastructure.
Structural engineering is the backbone of GM2. Our services encompass bridge inspection, load ratings, the design of new bridges and rehabilitations. From simple- to continuous-span bridges and complex, curved steel, highway structures, GM2’s structural engineers have successfully pioneered several ‘firsts’ throughout New England. Including the first fully precast integral abutment bridge, in Buckland, MA; GM2 used 100% prefabricated integral abutments and NEXT beams; a two-span Geosynthetic Reinforced Soil – Integrated Bridge System (GRS-IBS) bridge utilizing a common abutment, Bassett Road over I-91, North Haven, CT (pictured); a semi-integral bridge, Harbor Road to Saugatuck Island in Westport, CT, utilizing permanent sheet piling as the foundation and doubling as a seawall to protect the bridge against storm surges; and the Ultra-High Performance Concrete (UHPC) repairs of deteriorated beam ends, in consultation with the University of Connecticut and CTDOT, for I-91 over Amtrak Rail lines in New Haven, CT.
GM2’s structural engineering staff consists of licensed professional engineers and NBIS certified inspectors. Collectively they've completed the inspection of over 1,000 bridges and the rehabilitation/replacement of more than 1,100.
GM2's bridge inspection teams are highly qualified in field experience and training/education (meeting all NBIS qualifications), thus allowing for swift mobility such as standard cycle frequency inspections (Routine, Complex, FCM), Damage (Special) or Emergency based evaluations. They are experienced in the safe operation of all types of under-bridge inspection units and self-propelled manlifts; in coordination with traffic control suppliers and railroad flaggers; and have built personal relationships with numerous vendors that are critical to obtaining necessary equipment and in facilitating seamless coordination.
