Full report
Edmond Public Works Authority has approved a $3.459m increase to Carollo Engineers’ professional-services contract for two wastewater projects at the Coffee Creek Water Resources Recovery Facility, as construction delays and aging plant infrastructure add to the engineering workload.
The authority voted 5-0 on October 26 to approve Contract Amendment No. 4, increasing the Carollo contract by $3,459,000.24. The amendment covers the CD16-00006 Coffee Creek WRRF expansion and the SS24-00007 clarifier rehabilitation and filter splitter-box improvements project.
A water resources engineer told the authority that the expansion is a longstanding project that has added a new headworks, a new UV system and other core treatment and compliance components. Costs included in the amendment are associated with construction delays and other issues involving the project contractor.
The second element of the amendment concerns rehabilitation of existing clarifiers that were not included in the earlier expansion project. Staff said the assets are aging and that Carollo’s added scope includes design, bidder prequalification and construction-management services.
The amendment had previously been considered by the Public Works Commission on October 14, where it was voted forward for approval.
The decision advances engineering support across both new and existing process infrastructure at Coffee Creek: the expansion is adding treatment and compliance facilities, while the rehabilitation package targets the condition of the plant’s current clarifiers and associated filter splitter boxes.
