RE: City of Waukee
11th and 17th Street Culverts
Change Order No. 1 / Final Pay Estimate / Project Acceptance
Dear Mr. Koester:
We have coordinated with the Contractor and City staff performing field observation. And find the
above referenced project to be in substantial completion. As such you will find the following
enclosures:
• Change Order No. 1
• Final Pay Estimate
• Project Acceptance Certification
Change Order No. 1 is a balancing change order for the above referenced project showing
adjustments to the contract bid quantities and dollars to reflect final constructed amounts. The
original contract amount was $564,004.00 and the final construction cost was $568,089.00. The
$4,085.00 increase is due to the adjustment of contract quantities, there were no other change
orders.
No additional work has been performed since Pay Estimate No. 7. A Final Pay Estimate including
Change Order No. 1 is attached. There is no payment due at this time.
Additionally, we have coordinated with the Contractor and City staff performing field observation
and a final project walkthrough was held on May 14, 2026 to develop a punch list. We find the
project to be in substantial compliance with the Plans, Specifications, and Change Orders
governing construction of this project within the contract period. As such, following satisfactory
completion of the punch list, we recommend the City accept the project which will initiate the start
of the four-year maintenance bond as specified in the contract documents. 30 days after project
acceptance, we recommend the City release the 3% held retainage in the amount of $17,042.67
to:
Nagel Construction, LLC
2601 140th St.
Allerton, IA 50008
The Project Acceptance Certification should be executed following City Council action to accept
the project.
Please contact us if you have any questions.
