The Rhode Island Department of Transportation Woonasquatucket River Bridge Design Build Project, located in Providence, involved the full superstructure replacement of the single span Bridge No. 604 on US Route 6. Manafort Brothers, Inc. was selected as the Design Build Prime Contractor to design and construct the bridge replacement on an aggressive schedule.
Demolition work included the removal of the existing bridge superstructure over the Woonasquatucket River using tandem crane picks during an overnight closure. The bridge construction scope of work included substructure concrete rehabilitation, new steel plate girders, a reinforced concrete bridge deck, cast-in-place concrete end posts, approach slabs, highway paving, line striping, landscaping, and maintenance and protection of traffic. As traffic on US Route 6 was required to be maintained with two travel lanes in each direction, all construction was carried out over two stages to complete the work.
Manafort served as the Design Build Prime Contractor for the project and self-performed a majority of the work including demolition, excavation, concrete substructure rehabilitation, superstructure concrete, drainage, and roadway construction. Manafort’s extensive design build experience aided in this project being delivered safely, successfully, ahead of schedule. and on-budget.
Located in Bridgewater, MA, the High Street Dam was rated as a Significant Hazard by the MA Office of Dam Safety for impeding migratory fish passage, interrupting natural river processes, and contributing to local flooding. Manafort Transit was selected to remove the existing 12 ft high and 80 ft wide dam across the Town River and replace the 170 year old High Street Bridge to withstand 500-year floods.
Manafort’s demolition scope included the design and installation of a temporary cofferdam, consisting of 3,000 lb sandbags, to temporarily divert and relocate Town River to facilitate the demolition of the existing dam and appurtenances under fully dewatered conditions. Manafort was required to selectively demolish and salvage portions of the historic dam for re-use on site.
Manafort’s bridge replacement scope included the construction of two new cast in place concrete bridge abutments and wingwalls supported by 3 ft diameter drilled shaft foundations. The new bridge superstructure included structural steel framing and a cast in place concrete deck. In addition, Manafort relocated gas, sanitary sewer, storm drainage, and water main utilities and constructed all site finishes on the project including reprofiling of the river channel, extensive river bank restoration, concrete sidewalks, and bituminous pavement.
The Manafort team’s extensive demolition and construction experience, in addition to close coordination with all project stakeholders and agencies, aided in the environmentally sound, safe, successful , on-time, and on-budget completion of this project.
CTDOT Project 0079-0244 – I-691 Resurfacing, Bridge Rehabilitation and Safety Improvements was a major highway and bridge rehabilitation Design Build project aimed to improve travel conditions and increase safety for all users along the I-691 corridor from Meriden to Southington, CT. Manafort Brothers, Inc. was selected to make these critical repairs to the existing roadway and bridge infrastructure along I-691 under this Design Build contract.
Manafort’s scope of work included concrete pavement repairs, drainage improvements, bridge rehabilitation of 14 bridges, 17,000 SY of bridge deck waterproofing membrane replacement, illumination upgrades, new overhead highway signage, highway resurfacing and highway safety improvements along a 9 Mile stretch of I-691 Eastbound and Westbound.
The Manafort Design Build Team engineered and constructed cross slope correction to meet current roadway design standards as well as roadside upgrades to meet current MASH Safety standards.
Manafort’s leadership throughout the design development, permit application phase, quality control plan implementation, coordination with all project stakeholders, and overall construction execution led to the safe, successful, on-time, on-budget, and award-winning delivery of this design build project.
CTDOT Project 0158-0207 – Merritt Parkway Safety and Bridge Improvements located between Westport and Fairfield, CT, involved the rehabilitation of 10 mile of the Merritt Parkway, a National Scenic Byway listed in the National Register of Historic Places. Manafort Brothers, Inc. was selected to perform this multi-site, challenging project involving the rehabilitation of 10 historic bridge structures back to their original aesthetic and architectural features through detailed restoration work while actively managing challenging traffic conditions on the Merritt Parkway.
Manafort’s highway scope of work involved complex and daily traffic control and signing patterns, resurfacing, roadway rehabilitation, and complete highway drainage system replacement. Additional highway improvements included cross slope correction, removal of rock ledges and other fixed objects, installation of 40,000 LF of slip-formed concrete curb and gutter, full-depth concrete pavement replacement, patching of other deteriorated roadway, and 46,000 tons of hot mix asphalt (HMA) resurfacing.
Manafort’s bridge rehabilitation scope of work included the rehabilitation of the steel arch superstructure for Bridge 00728 over the Saugatuck River to upgrade the integrity of the severely deteriorated steel arch rib. The concrete substructure repairs required temporary supports in order to maintain active traffic and to facilitate bearing rehabilitation. In addition, the Merritt Parkway project required restoration and painting of multiple, aesthetically unique bridge superstructures where paint colors and concrete tones mirrored the existing construction.
Manafort served as the Prime Contractor and self-performed major aspects of the project including maintenance and protection of traffic, concrete bridge rehabilitation, drainage upgrades, roadway reconstruction, and slip-formed concrete curb. All work was completed safely, successfully, on-time, and on-budget through extensive coordination with the CTDOT.
