City Council Regular Meeting

Meeting Date:

07/28/2020

BACKGROUND

In order to make the City of Schertz water system work more efficiently and provide better service to customers, a dedicated transmission main is needed to connect the Live Oak Tank to the I-35 Elevated Tank. These tanks are currently not directly connected, so the I-35 Elevated Tank is fed through the distribution network. Operating in this manner requires the distribution system to operate at a higher pressure than ideal, which is undesirable for residents near the Live Oak Tank site, and also causes operation and maintenance issues with the pumps and pipe network due to the pressure stress on the system. This dedicated transmission main is proposed to be a 16” line.

Because of the scope of the project, the design consultant services are planned to be broken in to two phases. The first phase, which is what is being awarded with resolution 20-R-81, includes a route study to select the best route for the project considering existing utilities, right-of-way/easements, and environmental concerns. The first phase also includes the development of a Preliminary Engineering Report which will include 30% plans. The second design phase of the project will include final design, bid, and construction phase services.

City Staff is recommending awarding the engineering services to Kimley-Horn because of their experience in completing similar transmission main projects that require extensive coordination and their ability to provide the majority of the required services within their local office. Kimley-Horn is one of the City’s current On-Call Consulting Engineer Firms.

The 16” Dedicated Transmission Main Project is a planned project that was included in the FY 19-20 Water Reserves budget.

GOAL

To obtain authorization from City Council to execute a task order agreement with Kimley-Horn Associates, Inc. to complete the first phase of design for the 16” Dedicated Transmission Main Project.

COMMUNITY BENEFIT

Completing the installation of the dedicated transmission main will improve service to City of Schertz customers and reduce operation and maintenance costs.

SUMMARY OF RECOMMENDED ACTION

Approve 20-R-81 to authorize the professional services with Kimley-Horn Associates, Inc.

FISCAL IMPACT

City Staff is requesting the base contract for phase one of design be awarded in the amount of $255,198 with a contingency of $38,802 for a total not to exceed amount of $294,000. Funding for the project was budgeted in FY 19-20 budget out of Water Reserves.

RECOMMENDATION

Staff recommends authorization of the task order agreement with Kimley-Horn Associates, Inc. to complete the first phase of design for the 16” Dedicated Transmission Main Project as identified in the attachments hereto.
