The General Dynamics Electric Boat South Yard Assembly Building is a new main assembly building and an integral part in the construction of nuclear-powered submarines for this major defense contractor. As part of this project, Manafort Brothers, Inc. was selected by AECOM Construction, Inc. to perform the civil, utility, precast concrete structure grouting, railroad track work, and site cast-in-place concrete work for the new 190,000 SF building. Located in Groton, Connecticut, the South Yard Assembly Building is now a key facility for large-scale submarine module assembly, advanced systems integration, and efficient manufacturing and testing.
Manafort’s civil and utility scope included site clearing, support of excavation, structural rock excavation, segmental retaining walls, as well as drainage, sanitary, and water utility installations for the assembly building project. Manafort installed a new railroad track and switches interconnecting with the existing rail lines through the ship building facility. Manafort’s concrete scope included substantial grouting of the precast pile caps, panel slab perimeter joints, and pile plugs.
Manafort self performed all of the civil & utility and concrete work while extensively coordinating with the entire project team to successfully complete the project safely, successfully, on-time, and on-budget.
