ELECTRIC BOAT SOUTH YARD ASSEMBLY

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.

CTDOT NEW HAVEN RAIL YARD MAINTENANCE OF WAY BUILDING

CTDOT Project 0301-0124 – New Haven Rail Yard Maintenance of Way Building located in the Metro-North New Haven Rail Yard in close proximity to New Haven Union Station, involved the construction of a new 25,000 square foot maintenance facility for the Metro-North Railroad personnel who maintain the main line and rail yard infrastructure as well as the locomotives. Manafort Brothers, Inc. was selected as a specialty contractor to perform the civil & utility work for the new Metro-North Railroad maintenance facility and employee parking lot as well as the associated utility and roadway relocations.

Manafort’s civil & utility scope of work included 259 permanent precast concrete pile foundations, support of excavation, structural excavation for building foundations, extensive contaminated dewatering, handling and disposal, contaminated soil disposal, transformer pads, electrical ductbank, telecommunications ductbank, gas service, sanitary sewer connections, storm drainage improvements, fire and domestic water utility services, excavation and backfill of interior underslab utilities, site lighting, curbing, landscaping, asphalt pavement, and pavement markings. Manafort’s concrete scope of work included the site finishes such as exterior bollards, equipment pads, sidewalks, and concrete pavement.

Manafort diligently coordinated with the construction manager, the CTDOT, the Metro-North Railroad, and all project stakeholders to perform the extensive civil & utility work for this project and self-performed the majority of the scope of work. All work was completed safely, successfully, on-time, and on-budget.

BRADLEY INTERNATIONAL AIRPORT CONRAC FACILITY

The Bradley International Airport Conrac Facility was a multi-building airport masterplan development project in Windsor Locks, CT. This major development replaced the existing off-airport rental car facilities that required passengers to use shuttles to access their rental cars by consolidating all car rental services to within a short walking distance from the airport’s terminals. In addition, the new Conrac facility added 830 public parking spaces as well as improved access to public transportation. Manafort Brothers, Inc. was selected to perform the concrete work for this 1.5M square foot state-of-the-art facility.

Manafort’s concrete scope of work included over 13,000 CY of concrete foundation components including footings, grade beams, walls, pilasters, columns, and piers to receive the precast concrete parking structure above. Manafort’s Team exercised its extensive experience with constructing parking structures to coordinate and eliminate potential field fit up issues between the cast in place concrete foundation elements and the precast concrete structure.

Once the facility was erected, Manafort constructed 5,600 CY of cast in place concrete topping slabs, 1,400 CY of slabs on grade, and 1,000 CY of slabs on metal deck. Manafort’s scope of work also included finishes such as equipment pads, parking access and revenue control islands, interior curbing.

Manafort’s proven experience constructing parking structures and attention to detail led this massive project to a safe, successful, on-time, and on-budget completion.

CTDOT NOROTON HEIGHTS RAILROAD STATION PLATFORM REPLACEMENT

CTDOT Project 0301-0170 – Noroton Heights Railroad Station Platform Replacement Project located at the Noroton Heights Railroad Station along the Metro-North commuter line on the Northeast Corridor in Darien, CT, involved the replacement of the existing railroad station platforms along Track 3 (New York Bound) and Track 4 (New Haven Bound). Manafort Brothers, Inc. was selected to upgrade the railroad station by raising the existing platforms, as well as the associated access stairways, ramps, and railroad station appurtenances in disrepair, to be compliant with the Americans with Disabilities Act.

Manafort’s demolition scope of work included removal and disposal of the existing precast concrete double tee flange railroad station platforms, stairs, ramps, and train passenger shelters along the train tracks. In order for the Noroton Heights Railroad Station to remain operational during construction, Manafort extensively coordinated with the Metro-North Railroad in order to keep the railroad station operational during construction. The work was required to be completed in several phases and during nightly track outages due to the proximity to the train tracks and overhead electrified catenary systems.

Manafort’s train platform scope of work included foundation upgrades, structural steel framing, cast in place concrete train platforms with embedded tactile warning surface, stairs, ramps, rub rail installation, ornamental railing, signage, and new passenger shelters. Manafort value engineered the platform design to be a cast in place structure in lieu of large prefabricated precast concrete elements to allow construction with smaller and less intrusive equipment minimizing impacts on railroad operations. In addition, potential delays due to unforeseen conditions were successfully mitigated by Manafort’s proven ability to increase labor and equipment resources on the project whenever necessary to be able to combine project phases and accelerate the project schedule.

Manafort served as the Prime Contractor on this project and self-performed major aspects of the project including train platform and railroad station appurtenance demolition, structural excavation, backfill, cast in place concrete train platform decks, foundation upgrades, stairs, handicap ramps, and sidewalks. All work was completed safely, successfully, on-time, and on-budget through extensive coordination with the Metro-North Railroad and the CTDOT.
