CITY COUNCIL MEMORANDUM

City Council Meeting:

April 7, 2026

Department:

Engineering

Subject:

Resolution 26-R-032 - Authorizing an amendment to the professional services agreement with Halff Associates for the FM 1518 Utility Relocation Project (B.James/K.Woodlee/E.Schulze)

BACKGROUND

City staff has determined that the City requires additional engineering-related services for the completion of the FM 1518 Water and Wastewater Relocation Project. Halff Associates, Inc. (Halff) has exceeded the project scope with respect to construction administration services and is requesting an additional fee to complete the project.

The original agreement with Halff for the design, bid, and construction phase services was for $548,370 with a not to exceed amount of $600,000 as approved by council on May 5, 2021, with Resolution 21-R-37. Due to additional design revisions requested by the City and TxDOT as well as increased coordination efforts throughout the construction phase of this project, Halff had previously been approved to reallocate their fees between “Data Collection” and “Utility Design” as well as to increase the construction phase services an additional $43,500. This increased the total contract amount to $591,870, which remained within the not to exceed amount originally approved.

Recently, Halff has been tasked with resolving conflicts with abandoned asbestos cement (AC) water lines that were not known to exist prior to design or construction beginning. These abandoned utilities required testing of their structural integrity to satisfy TxDOT in order remain abandoned-in-place without removal. Halff is requesting an additional fee of $25,000 since this effort was not included in their original scope of work. With this amendment, the total professional services agreement amount will be $616,870 and the new not to exceed amount will be $625,000.

GOAL

The goal of Resolution 26-R-032 is to obtain authorization from City Council to have Halff provide additional services toward completion of the FM 1518 Water and Wastewater Relocation Project.

COMMUNITY BENEFIT

The relocation of these lines will ensure the City utilities are provided in an alignment that allows adequate space for future maintenance, and prevents conflicts with TxDOT’s proposed roadway.

SUMMARY OF RECOMMENDED ACTION

Staff recommends that the City Council approve Resolution 26-R-032, authorizing an amendment to Halff’s agreement for the FM 1518 Relocation Project, for an additional amount of $25,000.

FISCAL IMPACT

Funding for the project was allocated from the City’s Water and Sewer Construction Reserves, bond proceeds, and ARP funds. The amendment to the task order is an additional $25,000 which is within the budget funded by those sources.

RECOMMENDATION

Approve Resolution 26-R-032.
