Committee forwards $936,879 low bid for citywide CIPP pipe lining to consent
Summary
Acting City Engineer Mike Dalila presented the 2025 cured-in-place-pipe rehabilitation project and recommended awarding the contract to the low responsive bidder, Iron Horse LLC. The engineer’s estimate was $1.6 million; three bids were opened and the low responsive bid was $936,879.16. Funding will come from storm and sewer funds.
Edmonds City Council Committee B heard a presentation Oct. 21, 2025, on the 2025 cured-in-place-pipe (CIPP) rehabilitation project and indicated consensus to forward the contract award to the consent calendar.
Acting City Engineer Mike Dalila described CIPP as a pipe-lining solution that inserts an impregnated felt liner that hardens in place and restores pipe conveyance without full excavation. The project is citywide, focused mainly on sewer pipes with one non-sewer site noted, and the packet included a map highlighting locations.
Dalila said the engineers’ estimate was $1.6 million. Bids were advertised Sept. 16 and Sept. 23 and opened Oct. 7; three bids were received and the low responsive bidder was Iron Horse LLC at $936,879.16. Dalila reported the firm's bid review was positive and that construction is expected to start in the fall and be complete by spring. Funding will come from the storm fund (04/22) and sewer fund (04/23); a funding breakdown appears in the packet (sheet 158).
Councilmember Ek asked how sites were identified; Dalila said the city inspects pipes every three to five years using high-resolution inspection footage and rates defects using the National Association of Sewer Service Companies (NASSCO) method to prioritize repairs. He said the city has alternated excavations and CIPP projects to manage backlog and that CIPP contractors are often from outside the region, which affects scheduling and procurement.
Committee members indicated consensus to forward the contract award to the consent agenda. The item will appear on the consent calendar for full council action; no roll-call vote was recorded at the committee meeting.
