CITY COUNCIL MEMORANDUM
| City Council Meeting: | December 2, 2025 |
| Department: | Engineering |
| Subject: | Resolution 25-R-165 – Authorizing a change order to the construction contract with Thalle Construction Co., Inc., relating to the Woman Hollering Creek Wastewater Project (B.James/K.Woodlee) |
BACKGROUND
The Woman Hollering Creek Wastewater Trunk Main and Lift Station Project (WHC WW Project) is part of the City's effort to establish and expand public wastewater collection and conveyance service to the southern portion of Schertz. With Resolution 21-R-106 City Council authorized a construction contract for $10,567,170 and a not to exceed expenditure threshold of $11,100,000 with Thalle Construction Co., Inc. (Thalle).
During startup of the new Woman Hollering Creek Wastewater Lift Station, it was noticed that an error had been made related to the installation of the main disconnect between CPS power and the lift station electrical system. Because the facility is within a regulated floodplain, all electrical equipment is required to be installed to a particular elevation. Without being recognized, the main disconnect assembly was not elevated as required. This was an oversight on the part of all parties involved in the project. In order to correct the situation, the contractor and their electrical subcontractor will construct a foundation and steel platform and will reroute the electrical conduit and cables and reinstall the disconnect panels at the appropriate elevation. The contractor proposes to perform the work with no overhead charges or markup of the electrical subcontractor.
The project is near completion and 13 change orders over the course of the multi-year project increased the contract amount to $11,099,041.59. The amount of this change order is $129,406.06 which will increase the total contract amount to $11,119,546.59 - exceeding the previously authorized not to exceed amount by just under $19,546.59.

GOAL
The goal of this resolution is for City Council to authorize the execution of a change order to the construction contract for the Woman Hollering Creek Wastewater Project with Thalle Construction Co., Inc., for $129,406.06 and increase expenditures with Thalle to an amount not to exceed $11,200,000.
COMMUNITY BENEFIT
The Woman Hollering Creek Wastewater Project in southern Schertz provides wastewater conveyance capacity for existing and new development in the Woman Hollering Creek sewershed. This project is providing the initial flow of wastewater to the CCMA southern water reclamation plant. Approval of this change order will allow for a correction of the location and configuration of the main disconnect for the lift station to comply with electrical and floodplain regulations. A properly elevated installation increases the protection and resiliency of the lift station which is a critical part of the City's wastewater infrastructure. This is in direct support of the City's strategic goal of infrastructure investment — particularly the objective of development and maintenance of wastewater infrastructure.
SUMMARY OF RECOMMENDED ACTION
Staff recommends that Council approve Resolution 25-R-165 to authorize execution of the change order to the construction contract for the Woman Hollering Creek Wastewater Project with Thalle Construction Co., Inc., for $129,406.06 and authorize a revised not to exceed expenditure amount of $11,200,000.
FISCAL IMPACT
The not to exceed amount previously authorized with Resolution 21-R-106 was $11,100,000. The change order being authorized by Resolution 25-R-165 increases that not to exceed amount to $11,200,000. Funds for the additional amount are included in the capital improvement plan project budget and are available in the wastewater capital recovery fund.
RECOMMENDATION
Approve Resolution 25-R-165.
