RECOMMENDED ACTION: Resolution to Approve Final Payment to A-1 Excavating, Inc.
for the Connemara Trail Extension Project, City Project 2018-09 and Accepting the
Improvements for Perpetual Maintenance
BACKGROUND
On March 17, 2020, City Council awarded a contract to A-1 Excavating, Inc. for the Connemara Trail
Extension Project, City Project 2018-09. This project constructed Connemara Trail from Akron Ave east
approximately 1,550 feet east. The project also included the extension of the stormwater trunk interceptor
line to the east along with water and sewer main.
With the development of the Emerald Isle subdivision, staff coordinated with the developer to extend
Connemara to the intersection with Aspen Avenue and the extension of the stormwater trunk interceptor
to avoid future utility crossings. This decision took advantage of the contractor’s low bid price for the
interceptor. This resulted in Change Order 1 awarded June 15, 2021 in the amount of $389,736.
A-1 Excavating has completed all the improvements as designed by WSB and Associates (WSB) and
detailed in the contract. As a result, WSB has recommended acceptance of the work and issuing the final
payment.
There are two change orders to this contract which resulted in an increase of $425,366.25. Based on the
final quantities the total construction cost is $2,105,142.09. This amount is $122,312.84 or 6.2% or above
the bid amount plus change orders of $1,982,829.25. The final payment amount is $83,035.24. The table
below shows the final construction cost details.
RECOMMENDATION
Staff recommends that the City Council adopt the attached resolution accepting the improvements for
perpetual maintenance and authorizing final payment to A-1 Excavating, Inc. for the Connemara Trail
