Rockmore Contracting Corp. v. City of New York
Attorneys and Parties
Brief Summary
Construction contract delay damages, including extended field office costs and extended site overhead (ESO), and contractual exclusion of weather delay damages.
Granted the City's motion for summary judgment dismissing Rockmore's delay damages for extended field office costs, ESO, and weather delays.
Reinstated a distinct category of ESO damages tied to services of the outside construction management firm J.S. Held (JSH).
Those JSH costs were documented, incurred post-bid, and unforeseeable at bid; issues of fact existed on causation by the City's delays and on waiver/documentation under the contract. The rest of the claims failed because they relied on bid estimates and because weather delays were contractually excluded and not solely caused by the City.
Background
Rockmore Contracting Corp. sued the City of New York for delay damages arising from a public construction project. The trial court (Supreme Court, New York County, Justice Melissa A. Crane) granted the City's summary judgment motion, dismissing Rockmore's claims for extended field office costs, extended site overhead (ESO), and weather delay damages. The City's position relied on established New York law that prebid estimates cannot be used to compute delay damages, and on a contract clause excluding weather-related delays. The Appellate Division noted precedent confirming that prebid estimates used to compute a bid are not a valid basis for recovery (Najjar Indus. v City of New York; Five Star Elec. Corp. v A.J. Pegno/Tully).
Lower Court Decision
The Supreme Court dismissed all delay-related damages claims—extended field office costs, ESO, and weather—finding Rockmore’s calculations improperly relied on bid estimates and that weather delays were excluded by the contract and were not solely caused by the City.
Appellate Division Reversal
The Appellate Division modified the order to reinstate Rockmore’s claim for a discrete category of ESO damages associated with project management services performed by J.S. Held (JSH). It held those costs were documented post-bid, were not based on bid estimates, and could have been caused by the City’s delays; factual issues remain regarding causation and whether Rockmore waived recovery by insufficient documentation under the contract. The court otherwise affirmed dismissal of extended field office costs, the remaining ESO items based on bid estimates, and weather delay damages. It also recalled and vacated its prior May 29, 2025 decision (238 AD3d 681).
Legal Significance
Reaffirms that prebid estimates cannot support delay damages in New York public construction disputes while clarifying that documented, unforeseeable, post-bid extended site overhead (ESO) costs—such as third-party project management—may be recoverable where issues of fact exist. Confirms enforceability of contractual exclusions for weather delays when the owner is not the sole cause (Henick-Lane, Inc. v 616 First Ave. LLC).
Contractors cannot use bid estimates to prove delay damages, but they may recover documented, post-bid ESO costs like outside project management if they show causation and compliance with contractual documentation requirements; weather delays remain barred if contractually excluded and not solely caused by the owner.
