Department:

Subject:

Resolution 25-R-064 - Authorizing a Task Order Agreement with Unintech Consulting Engineers, Inc., for Professional Services related to the Rehabilitation and Painting of the East Live Oak and Northcliffe Elevated Storage Tanks and Painting of the Ware Seguin Ground Storage Tank. (B.James/K.Woodlee)

BACKGROUND

The vertical fill and outlet piping in the East Live Oak and Northcliffe elevated storage tanks are showing increasing signs of fatigue and corrosion at their welded joints. This piping is critical to the operation of the tanks in the system. In order for the appropriate method of rehabilitation to be identified, examination and testing is necessary. Once results are available, the level of rehabilitation will be specified. That may include full replacement of the fill and/or outlet piping.

Generally, ground and elevated potable water storage tanks should be repainted inside and out every ten years. The Ware Seguin ground storage tank, East Live Oak elevated tank, and Northcliffe elevated tank are all overdue for this important maintenance activity. Since the rehabilitation of the fill and outlet pipes will require the draining of the tanks, staff plans to have the painting operation done during the same take-down period to save time, effort, and water loss.

Unitech Consulting Engineers is one of the City's on-call engineering firms and is qualified to perform this work.

GOAL

The goal of Resolution 25-R-064 is to authorize the execution of a task order agreement for Unintech Consulting Engineers, Inc., (Unintech) to provide professional services including survey, testing, evaluation, engineering, and construction phase services for the rehabilitation and painting of the East Live Oak and Northcliffe elevated storage tanks and painting of the Ware Seguin ground storage tanks.

COMMUNITY BENEFIT

Rehabilitation of corroded fill and outlet pipes in the East Live Oak and Northcliffe elevated storage tanks is critical to maintaining operation of the tanks and continuity of TCEQ-required storage volume and operational pressure for the City's water system. The same is true of the painting of those tanks along with the Ware Seguin ground storage tank. Periodic painting of the inside and outside of potable water storage tanks is important to prevent corrosion and maintain the quality of water in the system. This maintenance of the City's water infrastructure is a direct benefit to the community that relies on the predictable availability of water.

SUMMARY OF RECOMMENDED ACTION

Staff recommends approval of Resolution 25-R-064 authorizing the professional services task order agreement with Unintech for the rehabilitation and painting of the elevated and ground storage tanks.

FISCAL IMPACT

A base amount of $93,517 and a not-to-exceed total of $115,000 is proposed for this professional services agreement. Funding of $100,000 from bonds for this project is allocated in the Combined Capital Improvement Plan from bonds and the remaining $15,000, if needed, is available in the water operating budget. The construction cost estimate for the combination of the tank piping replacement and tank painting is currently $2.2 million. The current budget, made up of a combination of bond funding and operation reserves, is $2.5 million. As the actual scope of the project is developed through the evaluation and design work, funding may be shifted as needed to accommodate the extent of required construction.

RECOMMENDATION
