As a subconsultant, SI Engineering, P.C. (SIE) provided design-build project delivery and construction quality assurance services for the Hunts Point Interstate Access Improvement Project – Contract 1, which improved access between the Hunts Point Peninsula and Sheridan Boulevard and the Bruckner Expressway. The project addressed structural and operational deficiencies.
The scope of this project included new ramps to and from Edgewater Road to provide access to the Hunts Point peninsula from the eastbound Bruckner Expressway and from Sheridan Boulevard, which required construction of retaining walls, abutment piles, soil displacement piles installation, and construction of integral abutment bridges. The scope also included a pedestrian bridge replacement which required substituting existing structural members over Amtrak and CSX train tracks, replacement of three bridges, and ramp relocation for the eastbound entrance ramp. Work also involved the replacement of concrete decks and the repair of other deteriorated elements of the Bruckner Expressway viaduct and ramps. Bruckner Expressway was widened, with construction of new piers, concrete deck replacement, replacement and installation of new bearings, and structural steel painting.
The project included pedestrian improvements such as a construction of a shared-use path for pedestrian and bicyclists connecting Garrison Park and Concrete Plant Park, which included a railroad crossing, and local intersection improvements, with pedestrian access components. The construction of a shared use path involved steel H-Piles and waterproofing installation, depth excavation and disposal while surrounded with live traffic, use of architectural concrete formliner to match precast concrete finishes, landscaping, and coordination with NYCDPR.
The scope also involved relocation and improvements of utilities, including relocation and replacement of the 12” water main with a 20” water main. Drainage improvements included resetting the existing catch basin and installation of new catch basin structure, RCP, DIP, and drainage outflow.
