Addendum No. 1

The following amendments, additions, deletions shall be made to the contract documents. In so far as these documents are at variance with this Addendum No. 1 dated May 23, 2024, the addendum shall govern:

Questions & Answers

Pre-Bid Conference Agenda, Minutes, and Record of Attendance

Revised Bid Schedule

Question 1 is from Andrew Manning of Synthetex:

1. There is a typical cross section detail on sheet C5.24 that calls out “Woven Unimat”, but also has a callout for “8 Point Fabric Form”. For context, Unimat is an available style that when installed produces a mattress of a relatively uniform section that is similar to a traditional concrete slab, where 8 Point Fabric Form seems like a similar callout that we often see for 8” Filter Point Fabric Form. Filter Point is similar to unimat but has woven points in the mattress that allow for the relief of hydrostatic pressure. I would also like to note that the material specification on the same sheet calls for Unimat with weep tubes, which is a uniform section mattress with plastic tubes installed to also allow for the relief of hydrostatic pressure. Both unimat with weep tubes and filterpoint would perform similarly, we just want to make sure that we quote the intended solution.

Response: Both unimat with weep tubes and filter point are acceptable. Documents require 8” nominal mat thickness.

Questions 2 through 9 are from Bill Capehart of IPC Paving:

2. Can the contractor change the proposed paving joint lanes to accommodate paving means and methods?

Response: Yes

3. Are there any height restrictions for the proposed concrete batch plant?

Response: Yes. The plant must be below the approached and departure surfaces of

Runway 1-19 and will require airspace review and clearance by the FAA. A plant has been established at this location previously without any issues.

SAC 30620 ADDENDUM NO. 1 A.1-2

4. Is power and water available at the proposed plant site?

Response: Water may be obtained from the nearest hydrant, which is approximately

1400 ft. along Gulfstream Road. Power does not exist on site.

5. Will the owner allow the use of Type 1L cement in the production of P-306 and P-501 pavements?

6. Will the use of local GDOT approved materials be acceptable for the production of P-306 and P-501 pavements?

7. Is ready-mix concrete from local suppliers acceptable for this project?

Response: Yes, but the mix design proposed must meet the specifications.

8. The proposed plant site appears to have excess materials stockpiled on the site, is the contractor required to relocate these materials to a different location to construct the plant site? What type of materials are stockpiled at this location?

Response: The material stockpiled is excavated material from a drainage project in the SE quadrant of the airport. This material is of unknown quality but may be used as non-structural fill on the project. Since the quantity is unknown, the

Commission and the selected contractor will define the quantity to be moved and used in the project and will negotiate a project credit for the material value

9. Can you please provide a list of contractors who have purchased plans for this project?

Response: Yes.
