INTRODUCTION
Dubuque
All -Americo City
2007-2012.2013
2017*2019
The enclosed resolution provides for the acceptance of the public improvement
construction contract for the Wilbricht Lane Detention Basin Project.
BACKGROUND
The Fiscal Year 2022 CIP Budget established $457,993.00 for the Wilbricht Detention
Basin Project. The detention basin improvements were designed to address localized
flooding that has occurred along Glendale Court and reduce the flow of runoff to alleviate
flooding issues on Marmora Avenue and behind the homes on McPoland Avenue.
In April of 2022 the City Council adopted Resolution 124-22 approving the plans,
specifications, form of contract and estimated cost for the Wilbricht Lane Detention Basin
Project, in the estimated amount $ 448,323.50.
In May of 2022, the City Council adopted Resolution 172-22, awarding the construction
contract for the Wilbricht Lane Detention Basin Project in the amount of $327,121.00 to
McDermott Excavating of Dubuque, Iowa.
DISCUSSION
Wilbricht Lane Detention Basin Project was completed by McDermott Excavating in the
final contract amount of $338,860.71. This is a 3.59% increase from the original contract
amount of $327,121.00. The increase was due to adding additional turf reinforcement
matting to help prevent erosion and establish the final grassed ground cover. A small area
drain was also added to prevent standing water downstream of the impoundment area.
RECOMMENDATION
I recommend that the City Council accept the improvements and authorize the payment
of the final contract amount of $338,860.71 to McDermott Excavating for the Wilbricht
Lane Detention Basin Project.
