Council approves Change Order No.10 and related amendments for wastewater treatment plant; net city cost increases noted

Council members approved Change Order No.10 on the wastewater treatment plant project and two related consultant and construction amendments that add net costs to the city while reflecting contractor and consultant credits.

Steven (staff) told the council that Change Order No.10 includes six work change directives that produce a $433,694.21 credit to the domestic budget and an $84,629.21 increase to the industrial budget; cumulative change orders total $3,153,611.72, which he said is a 3.15% increase to the overall project. "This change order number 10, puts us at an overall cost increase a total amount of change orders in the amount of $3,153,611.72," Steven said.

For a one-year extension of the overall project, Steven said the extra engineering services cost is about $799,408. To offset that, the contractor offered a credit of $448,000 and the consultant SEH would provide a $176,000 credit, leaving approximately $175,000 to the city. He also said redesign consultant fees for city-requested items total $240,592, and that amendment No.1 results in an added $416,000, bringing the engineering contract total to approximately $5,606,000.

Council moved and approved the change order (item 12), the consultant waiver (item 15) and the construction services amendment (item 16) by recorded votes (all motions passed by the votes recorded in the meeting). No member requested to table or amend these items during the meeting.

Why it matters: the approvals adjust the project’s budget and contract amounts and document how contractor and consultant credits were applied to limit the city’s net cost. The council’s approvals allow the wastewater plant work to continue under the revised schedule and contract terms.

Next steps: staff will incorporate the change orders and amendments into project accounting and contract documents per standard procurement and reporting procedures.
