The MassDOT Acceler-8 I-90 Bridge Replacement Project involved the rapid replacement of 8 bridges on Interstate 90 (Massachusetts Turnpike) over the course of 8 weekends in the summer of 2021. Using Accelerated Bridge Construction (ABC) methods, construction that would typically take years, and disturb traffic patterns and cause traffic jams, took less than 2 months. All work was performed and completed in weekend outages from 6pm on Friday evenings through 6am on Monday mornings, meaning each bridge was replaced in a mere 60-hours.
Manafort-Precision was contracted to perform all concrete and grouting work for the 8 bridges during the 60-hour shutdowns. Manafort crews worked three shifts around the clock within the tight work window to complete all of the required work. Manafort’s scope of work included forming, reinforcing, and placing new abutment walls at the Cordaville bridge, forming and placing closure pours and bridge barriers, installation of reinforcing, installation of bridge bracket working platforms, and grouting at the Cordaville, Parkerville, Woodland and Flanders East and Westbound bridges.
Due to the accelerated nature of the project, extensive pre-planning, advance preparation, prefabrication, communication and teamwork amongst all project parties was critical to the projects success. The end result was that all work was completed safely, very successfully, as planned, ahead of schedule, and under budget.
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.
