Council pauses on awarding wastewater plant contract after low bid tops $58 million

The Independence City Council on June 8 heard that bids for the long‑planned wastewater treatment plant modification project came in far higher than earlier estimates and agreed not to award a contract tonight, postponing any decision until a July 13 meeting.

Chair (speaker 1) read the three bids presented by staff: the low bid, from Woodruff Construction of Waterloo, was $58,176,300; the second bid from Wendler, Inc., was $61,900,000; and a third bid from Tricon General Construction was $66,700,000. “The lump sum bid is 58,176,300,” the Chair said.

Council members pressed staff and the city’s engineering consultant about why estimates had risen from roughly $30–35 million in early planning to the $43 million figure used for a loan application and now to bids around $58 million. A council member asked, “Where were these numbers so far off in 3 and a half years’ time?” (speaker 6).

The engineering consultant (speaker 11) said earlier estimates represented high‑level planning numbers and that contingency allowances had proven insufficient. He described a volatile post‑COVID bidding climate and explained that unit prices — the contractor’s cost per cubic yard, lineal foot or similar item — drove much of the difference. He told the council the bidding climate nonetheless appeared competitive: “The difference between the 1st and 2nd bid was about 6.4%. So that indicates a good bidding climate,” he said.

Council members explored alternatives, such as value‑engineering and requiring U.S.‑made components, but staff and the city’s bond counsel warned that changing the scope substantially would require rebidding under Iowa procurement rules and could delay the project by many months. One council member said the city risks further price escalation if it restarts bidding; another warned the existing plant is aging and hard to keep running without new parts.

Staff stressed that tonight’s item was informational and that the city would not ask the council to approve a contract until financing and funding options were identified. The engineering consultant said he would return to the July 13 meeting with more information.

What happened next: Council approved the underlying procedural resolution to confirm plans and specifications related to the project earlier in the meeting, but the actual contract award was deferred so staff can present funding options and any recommended adjustments before a final decision.

Why it matters: The project replaces and modernizes nearly 50‑year‑old equipment at the city’s wastewater plant; the gap between planning estimates and contractor bids requires the city to balance ratepayer impacts, available loan programs and construction timing.

Next steps: Staff and consultants will meet with bond counsel and lending partners to identify financing options and will return to council with a funding plan and any recommended scope changes at the July 13 meeting.
