Superstorm Sandy, with its historical storm surge, caused massive damage to approximately 60 New York City Housing Authority (NYCHA) developments. Three developments on the Rockaway peninsula were severely damaged and required extensive repair as part of NYCHA’s Hurricane Sandy Capital Improvement Program (HSCIP) Category 3 projects. These developments were the Redfern Houses—an 18.78-acre complex consisting of nine buildings with 604 apartments; Hammel Houses—a 14.16-acre complex consisting of 14 buildings with 712 apartments; and Carleton Manor—a 3.33-acre complex comprised of an 11-story building with 170 apartments.

Under NYCHA’s Sandy Recovery Program, the FEMA-funded repair and remediation of each development included: flood proofing above Advisory Base Flood Elevation (ABFE), as determined by FEMA, to protect building envelopes; installation of backup generators and the associated equipment; removal and replacement of damaged site-wide underground conduit, feeders and site lighting; replacement of existing damaged boilers and associated mechanical equipment, electrical equipment, and electrical distribution equipment above the Design Flood Elevation (DFE); roof replacements; and the restoration of site elements to pre-disaster condition.

As the cost estimator, TCT prepared construction cost estimates broken down by scope of work for construction sequence, trade, and CSI Code for each of the projects at 50% and 100% construction documents phase. The estimates were presented in a unit price cost breakdown structure tied to the Master Project Schedule, and each estimate was based on quantity take-off, local trade and material indexes, prevailing and/or union wages. Additionally, TCT prepared estimate revisions, review and analysis of bid breakdowns, and compared bids with the final estimate for each of the developments.
