MCINNIS CEMENT TERMINAL EXPANSION

Located along the Providence River at the Port of Providence, RI the McInnis Cement Terminal was the first US Terminal for Canada based cement manufacturer, McInnis Cement. This cement terminal has the capacity to serve the New England Construction Market with its distribution of cement products to Rhode Island, Massachusetts, and Connecticut from this convenient terminal location. Manafort Brothers, Inc. was selected to perform the civil & utility as well as concrete scope of work for the expansion of this cement terminal.

Manafort’s civil & utility scope of work included structural excavation for new dome silo storage facility and associated support frames as well as site preparation for the new electrical equipment building and cement loadout structure. The dome silo measured 134 feet in diameter and has the capacity of storing 40,000 tons of cement.

 

In addition, Manafort performed the storm drainage upgrades, electrical service connection, and installed the new transformer pad for the cement terminal expansion. The site finishes included curbing, asphalt pavement, pavement markings, signage, and fencing. Manafort’s concrete scope of work included construction of cast in place concrete foundations for the new dome silo, electrical equipment building, and load-out structure.   

 

Manafort’s extensive civil and concrete work experience led to the safe, successful, on-time, and on-budget completion of this project.   

YALE SCHWARZMAN CENTER

The Yale Schwarzman Center was a Yale University renovation project located in New Haven, CT, designed to provide a university-wide shared space to its community through restored spaces for student life to meet, dine, and collaborate. The project was constructed within and adjacent to the historical Yale University Commons, which first opened its doors in the early 1900’s. Manafort Brothers, Inc. was selected to perform the concrete, civil, and utility work for this complex renovation project that converted the original Yale University Commons to the Yale Schwarzman Center to fulfill Yale’s goal of unifying its student body.

Manafort’s civil & utility scope of work included site demolition, utility removal, pavement removal, new sanitary sewer connections, storm drainage upgrades, site lighting, electrical ductbanks, excavation and backfill for underslab utilities, support of existing utilities, structural excavation, support of excavation, construction dewatering, underpinning, interior excavation within the University Commons building, and site finishes.

 

Manafort’s concrete scope of work included structural walls, foundations, retaining walls, columns, piers, elevator pits, slabs on grade, slabs on deck, stairs, and miscellaneous flatwork.

 

The project was built on a small footprint with challenging site logistics in the heart of the Yale University campus 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 Yale University led to a safe, successful, on-time, and on-budget project completion.

HIGH STREET DAM REMOVAL AND BRIDGE REPLACEMENT

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 NOROTON HEIGHTS RAILROAD STATION PLATFORM REPLACEMENT

CTDOT Project 0301-0170 – Noroton Heights Railroad Station Platform Replacement Project located at the Noroton Heights Railroad Station along the Metro-North commuter line on the Northeast Corridor in Darien, CT, involved the replacement of the existing railroad station platforms along Track 3 (New York Bound) and Track 4 (New Haven Bound). Manafort Brothers, Inc. was selected to upgrade the railroad station by raising the existing platforms, as well as the associated access stairways, ramps, and railroad station appurtenances in disrepair, to be compliant with the Americans with Disabilities Act.

 

Manafort’s demolition scope of work included removal and disposal of the existing precast concrete double tee flange railroad station platforms, stairs, ramps, and train passenger shelters along the train tracks. In order for the Noroton Heights Railroad Station to remain operational during construction, Manafort extensively coordinated with the Metro-North Railroad in order to keep the railroad station operational during construction. The work was required to be completed in several phases and during nightly track outages due to the proximity to the train tracks and overhead electrified catenary systems.

Manafort’s train platform scope of work included foundation upgrades, structural steel framing, cast in place concrete train platforms with embedded tactile warning surface, stairs, ramps, rub rail installation, ornamental railing, signage, and new passenger shelters. Manafort value engineered the platform design to be a cast in place structure in lieu of large prefabricated precast concrete elements to allow construction with smaller and less intrusive equipment minimizing impacts on railroad operations. In addition, potential delays due to unforeseen conditions were successfully mitigated by Manafort’s proven ability to increase labor and equipment resources on the project whenever necessary to be able to combine project phases and accelerate the project schedule.

 

Manafort served as the Prime Contractor on this project and self-performed major aspects of the project including train platform and railroad station appurtenance demolition, structural excavation, backfill, cast in place concrete train platform decks, foundation upgrades, stairs, handicap ramps, and sidewalks. All work was completed safely,  successfully, on-time, and on-budget through extensive coordination with the Metro-North Railroad and the CTDOT.
