Loading...
Summary
Ridgewood Water staff recommended awarding a $7,477,971.58 contract to Conquest Construction for raw-water mains tying satellite wells to PFAS treatment facilities; officials also requested an $82,000 additional award for corrosion-control chemical and a $64,000 change order for the Ravine Mar treatment facility engineering contract.
Ridgewood Water presented three related items Dec. 4 tied to the village’s PFAS master plan build‑out and ongoing treatment projects.
Rich Kalbi, speaking for Ridgewood Water, said the department recommended awarding the third water‑main contract to the lowest responsible bidder, Conquest Construction Inc., in the amount of $7,477,971.58 to install over 25,000 linear feet of piping connecting seven satellite wells to PFAS treatment facilities at the Ames facility in Wyckoff and the Wharton Dyke facility in Midland Park. "They prepared the attached bid report...and recommended award to the lowest responsible bidder, Conquest Construction Inc, in the amount of $7,477,971.58," Kalbi said.
Kalbi also requested an additional award of $82,000 to ESC Environmental to cover higher-than-anticipated volumes of corrosion-control inhibitor chemical after a 30% increase in distributed water in October; he said multiple deliveries in November and December drove the need for the larger estimate. "We're asking for an additional award of $82,000 to account for the additional amount of chemical that's gonna be required to complete the year," he said.
Finally, staff requested a $64,000 change order to the professional engineering services contract for the Ravine Mar treatment facility to cover project delays (building delivery problems, added SCADA equipment) and to fund reviews required to secure a shore-connection permit from the Northwest Bergen County Utility Authority.
Officials told the council that funding for the main contract is included in the capital budget and will be financed through an iBank project loan; the contract recommendation and the additional awards were presented for instruction and formal action at a subsequent meeting or through the agenda process.
