County engineer recommends holding pipe purchase, presents tarping, gas‑management and overlay bids

Susan Eugenis, Cowlitz County engineer, asked commissioners to pull consent agenda item 2—a pipe purchase—because bid descriptions and the bid tabulation did not align and require correction before award.

Eugenis described consent agenda item 3 as the annual purchase of SCRM reinforced polyethylene membranes (tarps). She said Northwest Linings and Geotextile Products was the low responsive bidder at $98,798.29; the department received three bids and one was deemed nonresponsive.

Eugenis also summarized two motion items scheduled for consideration: a not‑to‑exceed contract with Energeoneering Solutions LLC for landfill gas‑management services, monitoring and SCADA support that includes second‑party verification of gas sampling results, and a bid award for the county’s 2026 overlay. The Energeoneering contract was described with a ceiling of $407,000 and an expiration date of December 31, 2028; the higher price reflects a new requirement for independent verification.

For the 2026 overlay, Eugenis reported a low bid from Lakeside of roughly $2.7 million, with Granite submitting a bid about $700,000 higher. She said staff pared back the project scope because asphalt prices (tied to oil) have risen; the county included a two‑week price‑adjustment clause common to state contracts to address short‑term fuel and material volatility. Eugenis told the board the county has about $3 million budgeted for the project to cover change orders if necessary.

None of these items were voted on at the meeting; several are scheduled as action items on an upcoming consent or motion agenda so commissioners may take formal action after staff corrects the pipe bid documentation and returns the item.
