Committee moves $60,000 WRF change order to consent after update on Phase 3 completion
Summary
The Parks and Public Works Committee was updated on substantial completion of the Water Reclamation Facility Phase 3 work and agreed to forward a $60,000 construction change order to the council consent agenda. Staff said the work increases treatment capacity and addresses out-of-scope items identified during construction.
The Snoqualmie Parks and Public Works Committee on Feb. 19 agreed to forward a $60,000 construction change order for the Water Reclamation Facility (WRF) Phase 3 project to the council consent agenda after an update from Public Works Project Engineer Andrew Vining.
Vining told the committee that the Phase 3 project is substantially complete and includes “completion of a new blower building, retrofit of both oxidation basins, new headworks equipment, and the new solids aeration system.” He said the new equipment “increases treatment capacity by 25%.”
Vining said several out-of-scope services identified during construction are included in change order 2. The largest items include stainless-steel air-gap piping to protect existing equipment and an innovative low-pressure mixing system installed to reduce solids accumulation. He described the mixer as a "big bubble" device that periodically flips open to mix the basin; operators have nicknamed it “King Solomon’s Chest.” According to Vining, the mixer cost about $2,000 and has reduced daily operator maintenance and associated odor issues.
Council member Brian Holloway asked whether the $60,000 is additional to the budget. Vining confirmed the funds were authorized in this year’s budget. Holloway noted the project’s CIP budget was $17,000,000, with about $378,000 unencumbered before the change order; after the $60,000 change order the project would remain about $318,000 under budget. Vining also said the Kimball Creek Lift Station work remains to be constructed this summer and is already contracted.
Chair Council Member Kat Cotton proposed moving the change order forward to the consent agenda; Holloway said he would pull the item from consent for discussion if he had questions next week. There was no recorded formal vote in committee; the item was referred to consent for full council consideration.
The committee heard no dissent to the referral. The change order and the Phase 3 completion will appear on an upcoming council consent agenda where the full council may accept, question, or remove the item for discussion.
The update and referral were presented as part of agenda bill AB24-034.
