PLAINFIELD RENEWABLE ENERGY POWER PLANT

The $225 million, 42 MW Plainfield Renewable Energy Power Plant in Plainfield, CT was, at the time of it’s completion, the only plant of its kind in Southern New England using wood based fuel to operate it’s biomass power generating facility. Manafort served as the Prime Civil, Utility, and Concrete Specialty Contractor on this project.

Manafort’s Civil and Utility work scope included 100,000 cy of earthwork, 20,000 cy of rock drilling and blasting, 35,000 sf of retaining walls, 8,000 ft of onsite piping, 30,000 ft of offsite piping including six stream and railroad crossings using trenchless technologies, and two 1700 ft long directionally drilled intake and discharge lines below and into the Quinebaug River. Manafort’s Concrete work scope required 20,000 cy of structural and mass concrete including foundation elements requiring Thermal Control planning and Mass Concrete measures and 1,200 tons of reinforcing steel.

Manafort self performed nearly all of it’s scope of work while also working closely with the entire project team under a very aggressive project schedule to coordinate and support a safe, successful, and on time completion of this facility.

ROUTE 8 BRIDGES REMOVAL & REPLACEMENT

The CTDOT – Design / Build Removal and Replacement of Bridges 03761, 03762, 03764, and 03765 along RT 8 in Bridgeport, CT was the first Design / Build Project performed for The Connecticut Department of Transportation.  This Accelerated Bridge Construction Project consisted of the demolition of 16 bridge spans and the design and construction of 10 new replacement bridge spans.  The work included demolition of the existing bridges, new bridge superstructures, bridge substructure repairs and modifications, cast in place concrete walls, earthwork, and roadway construction.

All work was performed using Accelerated Construction Techniques.  Manafort collaborated with it’s Design / Build Partner WSP Parsons Brinckerhoff to develop a detailed design that supported these Accelerated Construction Techniques most notably including onsite prefabrication of the bridge superstructure units.  The bridge superstructure demolition, reconstruction, over 30,000 cy of roadway and structural fill, and highway approach work was all completed ahead of schedule, four days less than the two, 14 day shutdown periods allowed by CTDOT.  Through detailed planning, prefabrication, scheduling, and coordination, it is estimated that Manafort completed two construction seasons worth of work during these two 14 day shutdown periods. 

The project was completed under budget, ahead of schedule, and was the recipient of a number of regional and national industry awards. Manafort served as The Design / Build Prime Contractor for the project and self-performed a majority of the work including demolition, excavation, cast in place concrete, onsite prefabrication of bridge superstructure units, road and highway work. 

PROVIDENCE VIADUCT I-95 SOUTHBOUND BRIDGE 578 REPLACEMENT

The Rhode Island Department of Transportation Providence Viaduct Southbound Bridge 578 Replacement Project involved the construction of a new 1,290 foot four lane bridge to carry RT 95 Southbound through downtown Providence, RI.  The Project also required removal and replacement of adjacent Bridge Ramp Structures 577 and 579 as well as widening sections of Bridge 578 and 579.  Due to very tight logistical constraints, the project required seven separate phases of traffic control and all work was required to be planned and scheduled in a very coordinated and detailed manner.

  

The work included extensive earth excavation and temporary support of excavation, pile driving, concrete substructure, bridge superstructure, temporary bridge, bridge demolition, cast in place concrete retaining walls, precast concrete retaining walls, storm drainage, roadway reconstruction, highway approach, highway signage, and highway lighting work.

Manafort developed and executed a number of value engineering approaches to complete the project including concrete slip forming of bridge parapets, the first ever application on a Rhode Island Department of Transportation Project.  Accelerated Construction Methods were also employed to complete construction of an interim highway ramp, to minimize traffic impacts on the general public, in 7 days, three days ahead of the 10 days required by contract.
       
Manafort served as Prime Contractor for the project and self-performed a majority of the work including excavation, temporary support of excavation, concrete substructure, bridge superstructure, cast in place concrete retaining walls, precast concrete retaining walls, storm drainage, roadway reconstruction, and highway approach work.

THE CLARK ART INSTITUTE – EXHIBITION AND RESEARCH

Manafort Brothers Incorporated was selected to perform the Architectural and Structural Concrete work for the new Exhibition and Research Center Project at the Sterling and Francine Clark Art Institute in Williamstown, Massachusetts. 

This very unique and specialized project was designed by renowned Architect Tadao Ando in collaboration with Gensler Architects and featured approximately 60,000 sf of exposed finished Architectural Concrete surfaces.  The highly architectural and exposed concrete made this a very challenging project.   Since the finished concrete surfaces were such a substantial feature of both the new interior and exterior space, every concrete placement was meticulously designed, planned, and executed to achieve the high architectural finish standards required by the Project Owner, Team, and the Architect himself.  All concrete placements were successfully completed to the satisfaction of all parties involved contributing to the highly successful completion of this award winning project.
