Project Title: Well Drilling and Aquifer Testing in Bay County, Florida

Deadline for Submission of Bids and the Opening of Sealed Bids is Tuesday, September 1, 2026, 2:00 P.M. ET.

This ADDENDUM NO. 1 is issued for ITB26B-003 Well Construction and Aquifer Testing in Bay County, Florida to provide answers to questions received during the inquiry period.

Attached are the questions and answers.

Question 1. Hi Jessica I am interested in Biding on this project but I am not seeing what kinda wells construction are they wanting to construct I see a few ads for bids so I am not to familiar with the process of how this bidding go

Answer: Potential bid respondents should review the information in the Invitation to Bid (ITB) packet which can be obtained from the District’s website (http://www.nwfwater.com), from the DemandStar website (https:// www.demandstar.com/app/login), or from the State of Florida’s Vendor Information Portal website (http://vendor.myfloridamarketplace.com).

Question 2: The tender documents indicate water level of -15-20 ft below sea level and site elevation approximately 5ft above sea level however the document goes on to discuss methods for controlling artesian flow above land surface. Can you confirm no artesian flow is expected as I would assume to be the case given aquifer and location.

Answer: It is not anticipated that artesian flow above land surface will be encountered during drilling based on available hydrogeologic and water level data, however the drilling contractor should be prepared to manage all types of borehole conditions including artesian flow.

Question 3: What type of fencing will be needed and where?

Answer: It is anticipated that silt fencing will be needed along the boundary between the temporary construction easement and any adjacent low-lying areas that may receive surface runoff. It is anticipated that free-standing chain link fencing (estimated height of 6 to 8 ft) with adequate work zone signage will be needed along the boundary between the temporary construction easement and the active roadway within the marina parking lot. Additional information is provided in Attachment A (technical specifications) of the ITB package.

Question 4: How far apart will the monitoring wells be as it may limit the type of drilling equipment used?

Answer: The anticipated approximate locations of the monitoring wells are shown on a site map and illustrated in a photo provided in the technical specifications. The area of the final monitoring easement is limited, and the monitoring wells should be approximately 10 feet apart.

Question 5: Can a shallow excavation be dug to install an in-ground mud circulation pan and is there a place to temporarily store excavated dirt?

Answer: The technical specifications state that an above-ground, mud-management system must be used to circulate drilling fluids and collect soil cuttings. The drilling contractor shall be prepared to drill without the need to excavate a mud-pit or install an in-ground mud pan. Shallow digging may be limited, as needed and approved, to facilitate site prep and equipment setup.

Question 6: Can the soil cuttings be spread or disposed of onsite?

Answer: No, soil cuttings must be transported off site and properly disposed of by the drilling contractor prior to demobilizing. Non-fluid soil cuttings may be temporarily stored within the construction easement during drilling activities. However, the area within the construction easement is limited, so it is anticipated that temporarily stockpiled or containerized cuttings will need to be periodically hauled off site throughout the project.

Question 7: Is there a place to discharge water during drilling, development and testing?

Answer: Mud and cutting ladened drilling fluid must be contained within an above-ground mud-management system with limited ground discharge within the construction easement area. No open discharge of muddy or excessively turbid water is allowed outside of the construction easement. Silt fencing shall intercept turbid surface water run off before entering adjacent depressions. Once pumped well water is free of excessive turbidity as determined by the District or onsite geologist, an area outside the construction easement where water from development and testing can be discharged will be identified. Per the technical specification, this area may be up to 500 feet from the pumping well and the drilling contractor shall be responsible for obtaining and complying with a NPDES permit, if required.

Question 8: What size pump will be needed for packer testing?

Answer: The borehole of the Floridan aquifer monitoring well will be a nominal six (6) inches. It is anticipated that the highest capacity pump allowable for that diameter shall be used.

Question 9: When do you plan to issue the notice to proceed (NTP)? Is this date flexible?

Answer: The project has been scheduled to start and finish during the park’s off-season when attendance is lower (typically fall and winter). It is anticipated that NTP will be given after October 1, 2026, and mobilization and site prep will begin in early November 2026, if not sooner. It is understood that a delay in starting may occur due to contractor availability. However, the project which is anticipated to take 2 – 3 months must be substantially complete, if not completed, by March 1, 2027.

Question 10: Do you have a cost estimate for the project, or can you disclose the project budget?

Answer: No, the District does not have a project budget based on current costs for the requested services.
