Bids opened for Sunny Side Creek drainage project and three demolition contracts

At a bid-opening session, staff recorded bids for the Sunny Side Creek Improvements wet detention pond and channel stabilization project (contract no. 1062) and three demolition/site‑clearance contracts. The announcements included engineer estimates, each bidder’s 5% bid security where noted, and the dollar amounts submitted.

The most expensive item by engineer estimate was the Sunny Side Creek Improvements project, with an engineer’s estimate of $2,249,102.50 for contract no. 1062. Four bidders submitted sealed bids: Boomerang Corporation of Anamosa, Iowa, $2,246,498.40; Connolly Construction Incorporated of Piazza, Iowa, $1,728,150.09; Peterson Contractors Incorporated of Rhinebeck, Iowa, $1,565,743.39; and Aaron Crane Construction LLC of Manchester, Iowa, $1,704,082.90. The session record notes each of those bidders provided a 5% bid security.

A second bid opening covered a demolition and site-clearance contract recorded in the transcript as “D‑2025‑13P” with an engineer’s estimate of $150,000. Three bidders were recorded: Lehman Trucking and Excavating of Waterloo, Iowa, $215,484 (5% bid security noted); Lansing Brothers Construction Incorporated of Luxembourg, Iowa, $293,800 (5% bid security noted); and D. W. Zinsser Company of Wofford, Iowa, $178,500 (5% bid security noted).

A third demolition and site-clearance bid opening, recorded in the transcript as contract “D2025‑01‑05P,” listed an engineer’s estimate of $85,000 and five bidders. Walker Reclaim and Demo LLC of Iowa Falls bid $71,188.45 (5% bid security noted); Benton Sand and Gravel of Cedar Falls bid $125,400 (5% bid security noted); D. W. Zinsser (listed as Wolford/Wofford in the record) bid $139,900 (5% bid security noted); Lehman Trucking and Excavating of Waterloo bid $67,341 (5% bid security noted); and Cedar Valley Excavating of Cedar Falls bid $77,210. The record includes a notation that Cedar Valley Excavating’s submission did not show a bid security on the scanned record.

No contract awards, motions, or votes were recorded in the transcript excerpt; the session documented the receipt and reading of bids and the presence or absence of the required 5% bid security. Further procurement steps — such as bid review, responsiveness determination, and award recommendations — were not included in the provided transcript.

Items of note from the session: the engineer’s estimate for the Sunny Side Creek project was $2,249,102.50; the three demolition projects had engineer estimates of $150,000 and $85,000 for the two demolition contract entries; and one bidder’s submission (Cedar Valley Excavating) was recorded without an apparent 5% bid security.
