The City of Nashua, Division of Public Works, is seeking sealed bids for the work as set forth in the attached plans and specifications for construction of the Phase III lined expansion landfill at the Four Hills Landfill, 840 West Hollis Street, in Nashua, New Hampshire. The scheduled work includes but is not limited to, site preparation, landfill liner base grade preparation, installing a double High Density Polyethylene (HDPE) plastic liner system, installing leachate collection and removal piping, pumps and appurtenances, and constructing storm water control infrastructure.
Please note that as of the date of this Invitation for Bid, groundwater data needed to provide a groundwater separation demonstration associated with the proposed landfill base grades is not complete. NHDES has required the City to continue collecting data through June 2019 in order to determine that the groundwater separation is adequate for liner installation. A final approval of the landfill base grades from NHDES is expected 30 days after submission of all required groundwater data. NHDES has specified that no work associated with liner system installation, including the 6-inch Screened Till layer, can begin until they have granted approval. All other work not associated with the liner system installation can commence after the contract has been executed.”
The City is now accepting bids electronically via Bid Express. Please review the attachments, Bid Express Vendor Guide and Vendor Set-up Guide for more information.
