CITY COUNCIL MEMORANDUM
| City Council Meeting: | May 21, 2024 |
| Department: | Engineering |
| Subject: | Resolution 24-R-53 - Authorizing a Resolution amending the Agreement with Cobb, Fendley & Associates, Inc., for Engineering Services for the Woman Hollering Creek Wastewater Project. (B.James/K.Woodlee) |
BACKGROUND
The City of Schertz is currently completing construction of the Woman Hollering Creek Wastewater Main and Lift Station project to collect and convey wastewater to the new Cibolo Creek Municipal Authority (CCMA) water reclamation plant off of Trainer Hale Road in southern Schertz. The system consists of approximately 14,500 linear feet of gravity main, 6,000 linear feet of force main, and a new lift station near Woman Hollering Creek at IH 10.
While delays related to materials needed for completion of the lift station significantly impacted the overall project schedule (original substantial completion January 2023 - currently expected completion June 2024), construction of the improvements is nearing completion. The slow progress over the past months has caused the need for consulting resources to increase beyond what was anticipated.
The City's agreement with its design engineer, Cobb, Fendley & Associates, Inc., (CobbFendley) requires further updating primarily due to the longer construction duration than originally assumed. The scope of construction phase services updated multiple times during the lengthy construction period is not adequate to allow for the level of effort needed from the design engineer through the remainder of the anticipated period of construction. It is also recommended that additional surveying services be used to confirm key elevations as constructed that may deviate from the original design.
The total estimated fee for the modified construction phase services that exceeds the most recently approved amount is $69,529.40. Staff is requesting that Council authorize a not to exceed increase to the agreement of $100,000. The difference between the consultant-proposed amount and the staff-requested amount will only be used if needed in the event that further delays or other unanticipated obstacles occur for which design engineer services are needed.
Attached to the resolution is a copy of the scope and fee amendment proposed by CobbFendley.

GOAL
The goal of this resolution is for the City Council to authorize an amendment to the Professional Services Agreement with CobbFendley to allow the City to continue the appropriate level of construction phase engineering services construction period of the Woman Hollering Creek Wastewater Project.
COMMUNITY BENEFIT
Providing the appropriate level of engineering construction phase services is necessary to ensure that this major capital infrastructure project is constructed with solid design control and technical oversight.
SUMMARY OF RECOMMENDED ACTION
Staff recommends authorization of the amendment to the professional services agreement with CobbFendley to establish an increased scope of services.
FISCAL IMPACT
Funding needed for the not to exceed amount requested is $100,000. That amount is available under the total funding for construction and ancillary tasks associated with the WHC WW Project. Funding for this project comes from a combination of 2013 Bond Sales and Wastewater Capital Recovery Funds.
RECOMMENDATION
Approve Resolution 24-R-53
