Wylie Water Treatment Plant Backup Power Improvements - Authorization for Alternate Project Delivery Method; Project No. 101-0564-20; Resolution No. 24-12
end
SUBJECT
recommendation
Authorize the use of Construction Manager At-Risk (CMAR) project delivery method for the Wylie Water Treatment Plant (WTP) Backup Power Improvements project.
end
PURPOSE
CMAR project delivery approach provides a distinct advantage for early identification and procurement of major equipment and systems that have traditional long lead times for configuration approvals, fabrication and delivery to the project site. Such equipment specific to this project includes large diesel generators, transformers and electrical switch gear. The CMAR delivery approach allows the procurement process to progress concurrent with the detailed design, which helps compress project schedule.
RECOMMENDATION
The Executive Director and NTMWD staff recommend the Board of Directors adopt Resolution No. 24-12, A Resolution authorizing the use of this alternative delivery approach in accordance with Texas Administrative Code Chapter 2269, Contracting and Delivery Procedures for Construction Projects.

BACKGROUND
PROJECT PURPOSE
• This project will enable the NTMWD to continuously monitor Oncor’s 138 kilovolt electrical service to the Wylie WTP and to transfer loads to the emergency backup generator system in the event of an Oncor power outage.
• In October 2023, the Board approved Administrative Memorandum No. TMP-23-31 authorizing final design of the Wylie WTP Backup Power Improvements. These improvements are based on the recommendations developed during the preliminary engineering phase as the most viable path forward for a dependable emergency backup power system.
• This action seeks the Board’s authorization for use of the alternative delivery approach.
• Future actions dealing with selection of a CMAR and Authorization of CMAR Preconstruction and Procurement Services will be brought at a later time. Other subsequent recommendations dealing with construction Work Packages will also be brought at a later time.
PROJECT COMPONENTS
• Centralized generator yard located just west of the north electrical substation;
• Generators will be sized to support 460 million gallons per day (MGD) of WTP treatment capacity;
• Design will meet requirements of Texas Senate Bill No. 3; and
• Supervisory Control and Data Acquisition (SCADA) system interface to assist control room operators.
FUNDING
None required at this time.
