CTDOT Project 0058-0336 – Bridge No. 03903 Mosher Avenue was a bridge rehabilitation project over Amtraks Northeast Corridor railroad right of way in Groton, CT. This existing single-span, 100-foot-long, and 2-vehicle lane structure was originally constructed in 1936 and was in need of functional and structural updates.
Manafort’s demolition scope of work included removal of the existing bridge parapets, fence, concrete bridge deck, and steel plate girders. A temporary water main relocation was required to maintain utility services to the adjacent buildings. All work was performed under close coordination with Amtrak under nightly track outages in order to protect the railroad tracks and electrified catenary system below, as well as maintain Amtrak’s train schedule and operations.
Manafort’s bridge rehabilitation scope of work included concrete substructure restoration, bridge bearing replacement, prefabricated bridge units, cast in place concrete bridge deck closure pours, architectural concrete bridge parapets, Amtrak electrification barriers, bridge grounding, permanent utility relocations, curb, sidewalk, asphalt paving, and line striping. Similar to the demolition phase of the project, all work over the active railroad was required to be performed at night under coordinated track outages.
Manafort’s extensive experience working within the Amtrak Railroad right of way and the use of prefabricated bridge units allowed the team to minimize the amount of work required to be performed over the active railroad, minimizing impacts on all project stakeholders. Manafort served as the Prime Contractor on this successful project and led the team to a safe, successful, on-time, and on-budget completion.
The West Haven Railroad Station Project involved the construction of a new railroad station located along the Northeast Corridor along the Metro North New Haven Line. Construction included a new station building, two 1,080-foot-long covered platforms with integral snow-melting systems, a pedestrian overpass bridge, elevator and stair towers, surface parking lots, and a pedestrian plaza.
Environmental work including contaminated soils and groundwater, new and modifications to the existing catenary systems, and installation of wayside Railroad signal equipment covering a distance of approximately 6 miles along the existing rail lines. This award-winning project was successfully coordinated, performed, and completed without incident as a team with Metro-North Railroad and CTDOT.
Manafort served as Prime Contractor for the project and self-performed excavation, cast-in-place concrete foundations and erection of pre-cast concrete platforms.
The Kingston Station Modifications & Capacity Improvement Project involved the construction of two new 850 foot long high level platforms comprised of pre-cast concrete platform sections supported on drilled micropiles and cast-in-place concrete pile caps. The project also included the construction of 8,250 LF of new rail bed as well as associated Overhead Contact System (OCS) catenary foundations and structures.
Through detailed project planning and phasing, Station operations and Train service were maintained throughout the life of the project. Train speeds through this region are some of the highest train speeds along the Northeast Corridor, approaching 150 mph. Working closely as a team with Amtrak and RIDOT, Manafort successfully coordinated and performed all demolition and construction work within the right of way without incident.
Manafort served as the Prime Contractor for the project and self-performed a majority of the work including demolition, platform excavation, cast-in-place concrete pile cap construction, pre-cast concrete slab fabrication and all pre-cast concrete platform installation.
The Wickford Junction Commuter Rail Station Project was the first Design Build and Public Private Partnership Project for the State of Rhode Island Department of Transportation. The project consisted of the design and construction of an 1100-space parking garage, an 850 ft high level platform, train station lobby, 3700 feet of new rail bed construction, on and off-site roadwork, and decorative hardscape and plaza work.
This Station is located on the Northeast Corridor with MBTA providing commuter service. The project was completed under budget, ahead of schedule, and was the recipient of a number of regional and national awards, including CMAA’s 2012 New England Infrastructure Project of the Year and an Honorable Mention for their National Project of the Year in the same category.
Manafort served as Prime Contractor for the project and self-performed a majority of the work, including retaining wall installation, excavation, parking garage concrete foundation installation, cast-in-place concrete pile cap construction, onsite pre-cast concrete platform fabrication, and all pre-cast concrete platform installation.
