ATCS is providing construction inspection services for this $189M project to replace the existing 3,300 foot long steel girder bridge north of the Baltimore Harbor Tunnel which crosses nine Norfolk Southern Railroad tracks, eight CONSOL Energy tracks, three CSXT tracks, three Canton Railroad tracks, Keith Avenue ramps to and from I-95, Newkirk Street, Holabird Avenue, and Ponca Street. The project also includes the replacement of the Holabird Avenue exit ramp and rehabilitation of the Baltimore Harbor Tunnel. Our inspection staff is supporting verification of construction stakeout for construction entrances, access roads, electrical, and bridge/pier footings, and providing inspection of temporary line marking, temporary signage, and road delineation. Our field staff was also responsible for inspection of debris lagging, demolition, survey, and inspection of excavations for pier footings and micropile installation, sampling concrete and grout as needed. As work progresses ATCS inspectors and project engineers, as part of the structures team, monitored, inspected, and documented friction piles, structural concrete and reinforcement, and MSE walls for compliance with the contract documents and requirements.
