DATE:07-22-25
DEPT:PW
SUBJECT:2023/24 CONCRETE STREET PAVEMENT IMPROVEMENTS PROGRAM
(PRAIRIE VIEW EAST AND PRAIRIE VIEW WEST)
COUNCIL ACTION FORM
BACKGROUND:
The Concrete Street Pavement Improvements Program is an annual program for the removal
and replacement of deteriorated concrete street pavements with a new pavement surface.
The project location for FY 2023/24 included Prairie View East and Prairie View West. On
March 12, 2024, City Council awarded the project to Con-Struct, Inc. of Ames, IA in the
amount of $1,015,443.
Change Order No. 1, a deduction in the amount of $26,991.68, was approved by the City
Manager's Office. This change order reduced the required quantity of asphalt surfacing
material and added the stabilization of subbase due to the presence of shallow utility
crossings.
Change Order No. 2 (this Council Action) in the amount of $230,500 is to cover
additional costs to place a new rock base and a concrete surface for the southern half
of Prairie View East. The initial project design had planned for milling and replacing the
surface of Prairie View East based on the pavement cores taken during the design
process. However, when construction began, it became apparent that the existing
roadway base was more deteriorated than expected.
This change order is necessary to ensure that the project can be completed, which will
reduce future maintenance issues with the pavement. It is anticipated that the more
substantial pavement construction provided by this change order will add
approximately 2-3 weeks to the construction schedule. The project is now anticipated
to be complete in early August.
The amount of $545,412 was transferred to this project from funds remaining from the 2023-
24 Asphalt Street Program #1. A summary of revenues and projected expenses is shown
below:

ALTERNATIVES:
1. Approve Change Order 2 for the 2023/24 Concrete Pavement Improvements Program

CITY MANAGER'S RECOMMENDED ACTION:
Including this additional work provides significant improvements to the longevity of the
Prairie View East roadway and reduces long-term maintenance costs. Therefore, it is the
recommendation of the City Manager that the City Council adopt Alternative No. 1, as noted
above.
