The School Construction Authority put a hard number on a Bronx roof job: $4,000,001 is the posted low end for exterior masonry, parapet, and roof work at Philip H. Sheridan, PS 21, due September 29.

That number is not a coincidence. SCA's estimate ranges routinely open one dollar above a round threshold — $4,000,000 in this case — a pattern that shows up across the authority's postings and typically signals a bonding or review tier tied to that exact figure rather than an engineer's actual midpoint guess.

“SCA's estimate ranges keep opening one dollar above a round number — that's not a guess, that's a threshold.”

The scope itself is straightforward envelope work: roofs, exterior masonry, and parapets at an occupied Bronx elementary school. That combination means noise and dust restrictions during the school year, scaffolding and sidewalk shed coordination, and a completion window that almost certainly avoids disrupting instruction — none of which is unusual for SCA, but all of which belongs in the bid.

With the estimate publicly posted at just over $4 million, contractors sizing their bonding capacity for this one have an unusually clear read going in — most SCA postings on this board carry no estimate at all, so a firm can rule itself in or out before spending estimating hours on the walkthrough.

The bid closes September 29. Firms without current SCA prequalification should treat that as the real deadline — prequalification, not the bid date, is what actually locks a contractor out of SCA work.
