RIDOT KENT DAM SPILLWAY BRIDGE

The Rhode Island Department of Transportation Kent Dam Spillway Bridge Project, located within the Scituate Reservoir in Rhode Island, involved the rehabilitation of the arched bridge along Route 12. Manafort Brothers, Inc. was selected to rehabilitate the three span arched bridge, originally constructed in 1924, carrying Route 12 over the Kent Dam Spillway on the south side of the Scituate Reservoir.

 

Manafort’s demolition scope of work included selective removal of the existing bridge parapets, arch fascia, and bridge deck concrete while working over the Scituate Reservoir. The concrete scope of work included the very detailed cast in place architectural concrete bridge arch restoration, bridge deck, bridge sidewalk, parapets, bridge curbing, and end posts. Manafort’s civil & utility scope of work included roadway widening along Route 12, drainage improvements, granite curbing, guardrail, rip rap slopes, and asphalt paving.

 

Manafort served as the Prime Contractor for the project and self-performed a majority of the work including excavation, bridge concrete rehabilitation, drainage, and roadway construction. Manafort’s extensive bridge construction experience aided in this project being delivered safely, successfully, on-time and on-budget.

CTDOT MOSHER AVENUE BRIDGE REPLACEMENT OVER AMTRAK

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.

CTDOT YANKEE DOODLE BRIDGE

CTDOT Project 0102-0348 – Yankee Doodle Bridge and I-95 over Norwalk River and Hendricks Avenue was a bridge rehabilitation project along I-95 over the Norwalk River in Norwalk, CT.  The existing 7-span- 911 foot-long and 8-vehicle lane structure was built over the river in 1958 and was in need of functional and structural updates. This major bridge rehabilitation project upgraded the bridge from a “Poor” rating prior to construction. Given the size of the structure, this improvement had a very positive impact on Connecticut’s bridge program.

The superstructure consisted of built-up welded steel plate girders and the substructure consisted of cast-in-place concrete abutments and piers. The proposed rehabilitation included major repair and complete painting of the deteriorated and deficient structural steel members, replacing deck expansion joints, repair of the bridge deck and substructure concrete, stabilization of the west abutment embankment and installation of a sedimentation pond, removal and replacement of the concrete parapets and median deck/barrier, maintenance and rehabilitation of the existing sidewalk, replacement of the bridge drainage, new navigational lighting, and upgrades to existing roadside elements.

 

Manafort’s creative approach to substructure repair work allowed for it to be completed without river channel closures below the bridge which minimized the impact on the local marine industry and promoted a positive relationship with the community.  Given the proximity to the Norwalk River, environmental compliance was also of great importance.  All blast media and debris associated with the preparation and new steel coating was contained, collected, removed, and properly disposed of.

 

All work was completed safely, successfully,  on-time, and on-budget in partnership and close coordination with the CTDOT.

KENMORE SQUARE BEACON BUILDING

The Beacon Building, steps away from Fenway Park, totaling 196,000 square feet, provides adaptable labs and workspace to inspire employees and accelerate discovery. Manafort-Precision was selected to perform the concrete work for this project as a part of the Kenmore Square Redevelopment.

Manafort’s scope of work included constructing the cast in place, reinforced concrete superstructure core as well as concrete foundations, walls, structural slab on grade, infill slabs to connect to the existing building, curbs, pads, and all concrete work associated with the site finishes.

 

The project was built on a small footprint in a congested urban area with challenging site logistics requiring extensive scheduling, coordination, and management of vehicle and pedestrian traffic. The Manafort team’s experience working in tight urban locations, commitment to safety and quality, and familiarity with High Rise Cast in Place Concrete work lead to a safe, successful, high quality, on time, and on-budget project completion.
