Four contractors submitted bids for the Primary Sludge Gravity Thickener Process Improvements at the Yonkers Joint Water Resource Recovery Facility, with ECCO III Enterprises, Inc. apparent low at $8,303,000, according to Westchester County Department of Public Works and Transportation's WestWorks bid results posting. Bids opened September 30, and the county has not yet confirmed an award.
Halcyon Construction Corp. finished second at $9,252,591, putting the spread between the top two bidders at 11.4%, or $949,591 — a meaningful gap on an $8.3 million job, suggesting the two low firms priced the mechanical rehab scope differently, whether on thickener drive equipment, process piping, or the coordination work that comes with keeping a live wastewater facility running during construction.
The posted record lists only two bids, ECCO III and Halcyon, even though the note states four bids were received — the other two amounts aren't included in what the county has made public so far. With only the top two numbers visible, the 11.4% gap is also, by definition, the low-to-high spread for the bids we can see; whether the full four-bid field spreads wider isn't knowable from this posting.
The project title tells the story on scope: mechanical rehabilitation of sludge thickeners at a joint water resource recovery facility serving Yonkers. That's wastewater infrastructure work, not a glamour job, but it's the kind of plant-process contract that keeps a treatment facility compliant and running — the sort of scope that specialty mechanical and wastewater subs should be tracking regardless of who ultimately wins it.
ECCO III is apparent low only; Westchester County's posting flags the result as pending confirmation, not a signed award. Firms with an interest in Westchester wastewater work should watch the county's WestWorks bid results page for the award notice, and keep an eye out for whether the county publishes the full four-bid tab.
