Summary & Background The current contract structure between Fulton County and the Joint Venture (JV) requires the Public Works Department to obtain BOC approval for all spending increases beyond the previously approved GMP (Guaranteed Maximum Price). This includes use of the project’s Owner Contingency funds. Upon approval the Public Works Department will allocate these contingency funds to cover all costs associated with this action. The work that is itemized below is required to complete the project and have the facility perform as designed.
Substantial Completion of the plant was achieved on August 6, 2025 and the JV is currently working to complete final punchlist items and site remediation. This BOC item represents the last request to access contingency funds the JV requires to complete this project.

These items were not included in the original GMP for the project, however, since the project has continued to be completed within budget, the remaining balance of the owner’s contingency is sufficient to cover these expenses. All of these elements will allow for improvements to the plant’s operation and the overall safety of the facility.
Currently the contractor has completed and is owed compensation for items #1 through #23 in the above table. The total costs associated with item #24 are still being finalized by the Joint Venture, but they have assured Fulton County that it will not be greater than the amount shown. Therefore, the actual change order amount paid to the Joint Venture may be less than the requested $4,810,722.17. Any cost savings from this final change order will remain with the Big Creek project.
Community Impact: No immediate impact to the community is expected from this item.
Department Recommendation: The Public Works Department recommends approval of this item.
Project Implications: Approval of this item will enable the Joint Venture to address critical operational improvements and punch list items necessary for overall project completion.
Community Issues/Concerns: No Community issues/concerns have been noted.
Department Issues/Concerns: The Public Works Department has not identified any concerns/issues with this request.
