Johnston awards contract for Pioneer Parkway sanitary sewer lining; project 20% under estimate
Summary
The Johnston City Council accepted bids and awarded a contract to Hydro Clean LLC to install a UV‑cured liner in a trunk sanitary sewer along Pioneer Parkway after a public hearing; the low bid was about 20% below the engineer's estimate.
The Johnston City Council voted unanimously on three related resolutions to adopt plans and specifications, award the construction contract, and approve the construction contract and bond for the Pioneer Parkway sanitary sewer lining project.
Council held a public hearing before voting. A staff presentation said the work will install a UV‑cured structural lining in the sanitary sewer trunk main along Pioneer Parkway to seal joints where tree roots have entered and caused flow restrictions. “The engineer's opinion of probable cost was $433,118. The low bidder was Hydro Clean LLC at $344,664.95, which is approximately about 20% underneath the estimate,” a staff member (referred to as Matt) told the council.
The project scope was described as spanning “from basically 60 down to Greendale Road along Pioneer Parkway.” Council members asked whether Hydro Clean has worked for the city before and whether the cost will come from utility operations. Matt replied that Hydro Clean has performed jetting and cleaning in the Des Moines metro and that the project will be funded from utility operations. Technical questions at the hearing clarified that roots will be removed from joints before lining and that the lining is structural and expected to “last 50 plus years.”
The council opened and closed the public hearing with no members of the public speaking; motions to adopt the plans/specifications/estimate (Resolution No. 25‑190), to make the award (Resolution No. 25‑191), and to approve the construction contract and bond (Resolution No. 25‑192) each passed on roll call with all voting members recorded as yes.
The council did not attach additional conditions to the award during the meeting. City staff said it would answer follow‑up technical or scheduling questions as needed during contract execution.
