Council held off on awarding $58 million wastewater plant contract after bids far exceed earlier estimates

Council members at the June 8 Independence City Council meeting paused action on a wastewater treatment plant construction contract after staff reported the low bid came in at $58,176,300, substantially higher than earlier public estimates.

The item began as a public hearing on the plans, specifications, form of contract and estimate of cost for the wastewater treatment plant modification project. City staff said the financing plan under consideration included a state revolving fund loan and cash reserves and that the resolution before council was the procedural step to approve the documents necessary to solicit and accept bids. Council approved those procedural documents on a 7‑0 roll call and was reminded that award of the construction contract would be considered at a future meeting.

When staff announced the three bids received — Woodruff Construction with the low bid ($58,176,300), Wendler Wl Inc. ($61,900,000) and Tricon General Construction ($66,700,000) — multiple council members expressed shock at how much higher the bids were than the $30–35 million or $43 million figures previously discussed in public sessions. One councilor called the discrepancy “grossly off,” and others pressed staff and the project engineer for detail on how unit‑price volatility, contingency allowances and post‑COVID supply and labor markets had produced the increase.

Bradley, the project engineer, told the council the low bid reflected a competitive bidding environment and volatile unit prices for many specialized construction tasks. “We distributed over a 100 drawings and specs to potential bidders,” Bradley said, adding the difference between the lowest and second‑lowest bid was about 6.4 percent, which he described as indicating competition. He cautioned that engineers set an opinion of probable cost but cannot control final unit prices contractors submit. He also said reuse of several plant components — the headworks and some buildings — had been included to limit costs where practical.

Councilors asked whether the city could pursue “value engineering” or require American‑made equipment to qualify for certain federal funding, but staff and the city attorney cautioned that rebidding or changing specifications would restart the procurement clock and require giving previously bidding contractors an opportunity to rebid. Staff also said some federal funding rules (and earlier choices about equipment origin) affect grant and loan eligibility. The mayor and staff emphasized that they were not asking the council to award the construction contract that night.

City staff committed to return at the July 13 meeting with detailed options for funding the project and comparisons of what changes (rebidding, specification adjustments or pursuing different funding mixes) would mean for cost and timeline. Staff noted construction could take roughly three to three‑and‑a‑half years once underway and that parts and system reliability on the existing nearly 50‑year‑old plant are an operational concern.

For now, the only formal action taken on the wastewater project at the June 8 meeting was approval of plans and specifications and scheduling the contract award for a future vote. The council will consider how to proceed — accept the low bid and identify funding, rebid after value engineering, or explore other procurement options — when staff returns with more financial detail on July 13.
