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.

BUSHNELL SOUTH PARKING GARAGE

The Capital Region Development Authority awarded Manafort Brothers, Inc. the Design Build Contract to design and construct the Bushnell South Parking Garage Facility in Hartford, CT.  With the recent renovation of the adjacent State of CT Office Building and planned mixed-use development projects, this new parking facility was one of the first steps in creating the new Bushnell South Park neighborhood. The new Parking Facility was needed to provide parking for the State of CT DEEP and Judicial Department employees, patrons of the Bushnell Theater, and future area residents while at the same time freeing up existing surface parking lots to allow new residential and commercial development.

 

This 411 space Parking Facility was built on the site of a former 5-story, 125,000-square-foot State of CT Laboratory Building, which Manafort also provided the hazardous material abatement and demolition services on a previous CT DAS project to allow for this new site development.

Manafort’s prime contract for the parking garage design and construction scope included structural excavation, disposal of contaminated soils, H-Pile foundations, cast in place concrete foundations, walls, slabs on grade, topping slabs, precast concrete parking superstructure, mechanical, electrical, plumbing, parking access and revenue control systems, site retaining walls, site utilities, and site finishes.

 

Manafort’s leadership and experience in Design Build projects, including numerous Parking Facilities, combined with our expertise and ability to self perform all site development activities including hazardous material abatement, soil remediation, demolition, civil and utility work, and concrete foundation, made this project a perfect fit.  Manafort completed the project safely, successfully, on-time and on-budget.

MARTIN LUTHER KING JR. SCHOOL

The Martin Luther King Jr. (MLK) School was established in 1922 and was originally named Weaver High School.  The school was a Collegiate Gothic masterpiece composed of three parts: a three-story main block for classrooms and two connected buildings for the gym and auditorium.  On September 21, 1976, the Hartford Board of Education renamed the former Weaver High School, the Martin Luther King Jr. School. In 2018, Manafort Brothers, Inc. was selected to perform the demolition, abatement, remediation, civil, utility, and concrete work as part of the complete renovation of this historical school building for the City of Hartford.

 

As part of the demolition scope, Manafort removed substantial amounts of asbestos-containing materials. This included friable pipe wrap, joint compound, boilers, and transite siding. Manafort crews immediately followed behind the abatement activity with a full 169,954 SF interior demolition (back to the structure supportive shell) of all non-structural building components.

Manafort’s concrete scope included cast in place concrete foundations, walls, piers, underpinning, slabs on grade, concrete restoration and low-density foam concrete fill for the existing school renovations. Manafort’s civil and utility scope included structural excavation and backfill, site retaining walls, as well as drainage, sanitary, water and fire service, gas, and telecommunication utility installations for the renovation project.

 

Manafort self-performed all of the work while also working closely coordinating with the entire project team under an aggressive project schedule. All work was completed safely, on time, and on budget.

NORWICH STATE HOSPITAL COMPLEX DECOMMISSIONING & DEMOLITION

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.
