body
DESCRIPTION
On March 22, 2023 the Southeast Board of Directors approved a contract with Youngquist Brothers Drilling, Inc. for the construction of the Southeast Injection Well 1 (SEIW-1). Construction of SEIW-1 is now concluding with final testing occurring in August and September of 2024. The well was constructed to a cased depth of 3,300’ with a total depth of 8,050’. Preliminary testing has indicated that the well will be able to accept the full amount of concentrate water from Phase 1 of the project. The total cost for the SEIW-1 is $18,888,000.
At the July 24, 2024 PRWC Southeast Wellfield Board of Directors meeting the Board will be asked to approve a contract amendment to allow construction of the West Polk Injection Well 1 (WPIW-1). In addition to the contract amendment, and in order to proceed with the construction of WPIW-1, the West Polk Board of Directors will be asked to consider a change order to the contract which allocates funding to the construction of WPIW-1.
The WPIW-1 Change Order (attached) provides for the following:
1) A construction contract time of an additional 1000 calendar days from Notice to Proceed to Final Completion with a substantial completion date of June 24, 2027;
2) An additional Construction Contract Price of $23,349,310 for WPIW-1 and the Dual Zone Monitor Well.
The full contract price is now $42,237,310 for both the Southeast and West Polk Projects injection wells and necessary monitor wells.
RECOMMENDATION
Approve the Change Order to the Youngquist Brothers Drilling, Inc. contract for the construction of West Polk Injection Well 1.
FISCAL IMPACT
The WPIW-1 is anticipated to cost $18,762,600 (inclusive of stand-by time and contingency, well acidification, and final demobilization costs) and the dual zone monitor well is anticipated to cost $4,586,710 for a total price of $23,349,310. This overall cost of WPIW-1 is higher due to the need to construct a dual zone monitor well at the West Polk site. The Southeast site also required appropriate monitor wells, but those wells were constructed as a part of Test Well #2 under a separate drilling contract. Southwest Florida Water Management District grant funds and the Water Infrastructure Finance and Innovation Act (WIFIA) loan have and will be utilized to fund the construction of both injection wells.
