Body
BACKGROUND:
The City of Carrollton has an existing contract with Klutz Construction LLC for the construction of the Coyote Ridge/Furneaux Creek Drainage Improvements project that was approved by council on May 21st, 2024. The Coyote Ridge/Furneaux Creek Drainage Improvements project consists of two projects that are unrelated in terms of scope and impact but were packaged together to create bidding efficiencies to obtain better pricing for the two project areas. The Furneaux Creek Drainage Improvement Project had the following scope: regrading the site, installing a sidewalk with an integral curb, installing a flume, and adding a concrete outfall channel/gabion mattress. The Coyote Ridge Drainage Improvement Project had the following scope: updating the Grandview Ridge neighborhoods drainage system by installing a new storm drain system, fixing the roadway pavement, and installing a steel flap gate on the existing box culvert pond outfall.
The Furneaux Creek Drainage Improvements required Change Order No. 1 for $19,875.00 which was approved internally on October 7th, 2024. This increased the original contract amount of $1,444,939.00 to $1,464,814.00. Work on the Furneaux Creek portion of the project is complete.
Coyote Ridge Drainage Improvements Project has begun with the construction of the new storm drain system for the Grandview Ridge neighborhood. This change order is requested due to an existing water main in Fairway Dr. interfering with the proposed location of a new storm line that is under construction. Field conditions of the water line did not match the as-built files, and the water main needs to be raised, and additional concrete roadway panels will need to be replaced.
The current proposed change order, Change Order No. 2 aims to accomplish the following tasks:
• Replace additional concrete roadway panels.
• Raise the city water main above the proposed storm drain system.
FINANCIAL IMPLICATIONS:
Current estimate from the contractor has priced the proposed scope change at $62,117.00. Staff is requesting an increase in the contract amount in the amount of the scope. Change Order No. 2 increases the current contract from $1,464,814.00 to $1,526,931.00, a 4.24% increase. Funding for the additional quantity is available in Account 854560, Drainage Consolidated funds.
IMPACT ON COMMUNITY SUSTAINABILITY:
By having the contractor address the utility interference and additional concrete panels that need to be repaired, the engineering department is ensuring that water service will continue to serve the citizens of the Grand Ridge neighborhood and that the streets will continue to provide a smooth and safe mode of travel for our citizens. This work is being performed by our contractor, which frees up the public works department to perform other necessary infrastructure related tasks for citizens and businesses within the community.
STAFF RECOMMENDATION/ACTION DESIRED:
Staff recommend authorizing Change Order 2 for Coyote Ridge/Furneaux Creek Drainage Improvements project in an amount not to exceed $62,117.00, increasing the total project contract to an amount not to exceed $1,526,931.00.
