Subject: Special Services Request No. 3-- Utility and Backup Power
Dear Mr. Groeschel:
This letter serves as Special Service Request No. 3 for additional engineering design related to
new utility power connections and additional backup generator capacity at the Stewart Creek
Wastewater Treatment Plant (WWTP). As discussed in our August 5, 2014 meeting, it has been
determined that the existing utility service and backup generation capacity is not adequate to
serve the planned plant improvements. New utility service and additional backup generation
capacity will be designed to accommodate Phase 1 and Phase 2 improvements. This effort will
also include coordination with Oncor in requesting the new service connections
As you recall, modifications to the existing utility power supply and backup generators were not
included as part of our scope under Basic Services. This effort was included as a Special
Service Task due to the many unknowns about existing capacity and future power
requirements.
The scope of work for this special service request will include upgrading the existing electrical
feed to the plant along with the addition of two new electrical feeds. Backup generators will be
provided for each of the three plant feeds. Additionally, it is our understanding the existing PLC
based automatic throwover switch (ATO) for the existing generator serving the main
switchboard is not functional. As part of this work, the existing ATO will be demolished and
replaced with a new automatic transfer switch (ATS), to match what is proposed for the two new
plant electrical feeds.
We request that $76,520 of the total budgeted amount of$90,000 for this special service task
be authorized. This amount includes $71,520 for Mbroh Engineering (Mbroh) for electrical
design services and $5,000 for Carollo for management, design coordination, and review. A
breakdown of Mbroh's cost is attached to this letter.
Please let me know if you have any questions or need additional information. I can be reached
at 817-882-0528 or jgallovich@carollo.com.
Sincerely,
CAROLLO ENGINEERS, INC.
