SUBJECT:2023/24 STORMWATER EROSION CONTROL (COLLEGE CREEK BANK
STABILIZATION - HEMINGWAY DRIVE)
COUNCIL ACTION FORM
BACKGROUND:
This annual program provides for stabilization of areas that have become eroded in streams, channels,
swales, gullies, or drainage ways that are part of the stormwater system. This program provides a more
permanent control of erosion and will reduce recurring maintenance costs in these areas. The location
for this project is College Creek near Hemingway Drive.
On February 19, 2025, bids for the project were received as follows:
BIDDER BID AMOUNT
Engineer's estimate $ 179,780.00
Jackson Contracting LLC $ 95,143.17
JC Midwest Services $ 115,957.50
TK Grading & Seeding LLC $ 127,278.00
Con-Struct Inc $ 135,948.00
Iowa Earth Works $ 157,704.00
Jorgensen Contracting Co.$ 180,095.00
HGS, LLC $ 195,470.60
During the bid review process, City staff identified discrepancies in the unit prices submitted by
the low bidder, Jackson Contracting LLC. The contractor listed a total bid amount $109,353.51.
However, after verifying calculations, staff discovered mathematical errors affecting multiple unit
prices, resulting in a corrected total bid amount of $95,143.17. The City policy found in the
invitation to bid documents states that 1) bids must be submitted on a unit price or lump sum
basis, as specified in the Proposal Form, and 2) if discrepancies exist in unit price extensions, unit
prices shall govern over the total amount.
City staff conducted a thorough review to ensure all bid packages were complete and included all
required documents. Based on the policy, the corrected total bid amount has been determined by
applying the unit prices provided in the bidder’s proposal. The Council should note that this
project required bidders to submit a bid bond that is 5% of the total bid amount. A bid bond is a
form of financial security that can be cashed by the City in the event that a bidder is unable or
unwilling to accept the contract after bids are opened. Jackson Contracting LLC has not
requested to withdraw its bid and has indicated to staff that it intends to honor its calculated unit
price amount. However, if such a request arose, staff believes the City would be obligated to cash
the contractor's bid bond.
