Site work for a water / sewer project in Miami, Florida. Completed plans call for site work for a water / sewer project.

The project consists of furnishing all labor, materials, and equipment to perform mechanical integrity testing (MIT) of nine existing injection wells at the Central District Wastewater Treatment Plant (CDWWTP) and one existing injection well at the South Miami Heights Water Treatment Plant (SMHWTP), complying with security restrictions; and all associated and appurtenant items and work as specified and as required by Miami-Dade Water and Sewer Department (WASD) during the course of the contract. The work includes suppressing the artesian flow of the wells with a food grade salt brine, removing the existing well head, scrubbing the 24-inch outside diameter (OD) seamless steel final casings with a steel wire brush, and scrubbing the 25.96-inch and/or 18.18-inch OD Fiberglass Reinforced Plastic (FRP) final casings with a nylon bristle brush (only for the three Industrial Injection Wells: CDIIW-1 and CDIIW-2 at CDWWTP, and SMHIIW-1B at SMHWTP), flushing with potable water, performing a high-resolution video survey log (VSL) of the entire well to see the casing and tubing joints as well as the open hole section, performing a pressure test up to 150 pounds per square inch (psi) on each well final casing, shutting in the well for a twelve-hour period, then performing high-resolution temperature (HRT) and conductivity logs, performing the radioactive tracer survey (RTS) using medical grade Iodine 131 (I-131), rebuilding the well head providing new 6 inch 100% gate valves (if necessary), replacing all gaskets, nuts, bolts, and painting all above ground piping. The contractor must also meet all security requirements, which include having all personnel who will be on-site fingerprinted. The work shall be performed first at the CDWWTP and, after its completion, at the SMHWTP property. Award of this contract will be made to the responsive, responsible bidder who submits an offer on all items listed in the solicitation and whose offer represents the lowest price when all items are added in the aggregate. If a bidder fails to submit an offer on all items, the offer will be rejected. The County will award the total contract to a single contractor who has complied with these requirements. In order to aid the County in making an award, the bidder shall submit, with the offer, written evidence of its qualifications and ability to begin construction, perform in a satisfactory manner, and complete all of the work covered by the contract within the time specified. The bidder shall submit proof of at least three similar projects within the past ten years involving MITs of Florida Department of Environmental Protection (FDEP) Underground Injection Control (UIC) permitted injection wells of 18-inch to 24-inch OD final steel casing and to a depth of at least 2,500 feet below land surface. Specialized testing activities including inflatable packer installation, casing pressure testing, VSL and HRT logging, RTS, and water quality sampling must have been completed to demonstrate relevant experience. Failure to submit this information with the bid may be cause for the Bidder to be deemed non-responsive.
