Originally built in 1904, the Norwich State Hospital grew over the decades to a 400 acre campus and amassed close to 60 structures before the State of Connecticut officially closed its doors in 1996. In 2009, the state sold the property to the Town of Preston to make way for the future development called the Preston River Walk. In 2010, Manafort Brothers, Inc. entered into a partnership agreement with the Town of Preston Redevelopment Agency (PRA) to facilitate the clean up of the property, which included abatement, demolition, and remediation of over 50 buildings, some four and five stories and over 200,000sf in size, connecting underground tunnel systems and PCB contaminated soils and building components. All told, Manafort successfully removed and abated approximately 1.4 million square feet of buildings under our agreement.
In addition to the abatement and demolition of the existing campus structures, Manafort’s scope was expanded to also include excavation and relocation of impacted soils throughout the site. During the facility’s 90+ years in operation, the base material used for their roads and travel-ways throughout the campus was predominantly coal ash from the facility’s on-site boiler and heating plants. Before beginning construction of their newly proposed Riverwalk complex, over 90,000cy of asphalt and associated bedding material throughout over 20 “Areas of Concern” needed to be excavated to varying depths and placed into two (2) large Consolidation Areas then capped with clean fill. At the time of completion, Manafort will have excavated, hauled, and capped over 200,000cy of impacted and clean material. Manafort worked hand-in-hand with the PRA and their environmental monitoring and engineering firm Tighe & Bond to successfully complete all remediation activities.
All work was performed successfully on-time and on-budget, in partnership with PRA and project stakeholders.
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.
The RIDOT East Shore Expressway Bridge No. 475 and McCormick Quarry Bridge No. 476 Replacement Project included complete replacement, substructure and superstructure, of two existing bridges and associated Roadway Approach work utilizing Accelerated Bridge Construction (ABC) techniques. To accomplish this accelerated replacement, advance work including new prefabricated bridge superstructures were constructed on top of temporary bridge supports in Bridge Staging Areas adjacent to the existing bridges and new Geosynthetic Reinforced Soil Abutments were installed to support these new bridges.
These prefabricated bridge sections were then transported and installed during two 80 hour traffic closure periods. Manafort’s detailed planning and scheduling of all required work activities, including substantial traffic control measures as these bridges are the connectors from RT 114 to I-195 in the metropolitan Providence area, supported the accelerated around the clock replacement operations during these 80 hour traffic closure periods.
The work performed during these shutdowns included demolition of the existing bridge structures, installation of precast concrete bridge seats, transporting and installation of the prefabricated bridge superstructures using Self-Propelled-Modular-Transporters (SPMTs), and construction of the approach roadways including the use of precast concrete approach slabs and barrier walls. The bridge replacements and roadway approaches were completed and opened for public use a combined total of 14 hours ahead of schedule. The project was completed under budget and ahead of schedule. Manafort served as Prime Contractor for the project and self-performed a majority of the work including excavation, cast in place concrete, onsite prefabrication of bridge superstructure units, road, and highway work.
