- HVAC
RENOVATION
RECOMMENDATION: We recommend the award of this project be made to
the evaluated lowest and most responsive contractor, Burley Coward
Mechanical, Inc. (BCI), Denton, Texas in the amount of $390,465.00.
SUMMARY: This project is for the renovation of the heating,
ventilation and air conditioning (HVAC) for the Municipal Building,
Civic Center, Senior Citizen Center, and the Library. The cost for
gas utility line extension has been deleted since Lone Star Gas has
agreed to pick up this cost of $12,188.00. The new proposed
chilled water loop to the newest portion of the Library has also
been deleted in the amount of $31,165.00. This loop was not cost
effective since energy efficient heat pumps currently are in use.
The dollars generated by these deletions will be utilized to
upgrade the system as proposed and for contingencies as they arise.
BACKGROUND: Memorandum dated 11/17/88 from Steve Brinkman to Betty
McKean presented to Council at a previous work session November 22,
1988, as backup to a presentation.
PROGRAMS, DEPARTMENTS OR GROUPS AFFECTED: Those affected by this
project are the various departments and groups using the specified
buildings and the Building Operations Department whose
responsibility it will be to maintain the system.
FISCAL IMPACT: The project is scheduled for a 10-year payback
utilizing funds generated from energy savings. The affected
departments will contribute funds from their line item budget based
on the projected savings for each department.

TO: ' Betty McKean, Executive Director for Municipal Services
and Economic Development
FROM: Steve Brinkman, Director of Parks and Recreation
DATE: November 17, 1988
SUBJECT: HVAC Renovation
We would like to present the three qualifying bidders for the HVAC renovation
of the city Hall, Civic Center, Library, and Senior Citizen Center. This
program will completely renovate the existing above-ground system and put it
in a like-new condition. It will also provide an energy management system to
help control the environment of all four buildings, thereby saving utility
costs and providing our crews instant maintenance information which will help
to lengthen the life of the equipment.
Of the three bidder9, we would like to recommend Burley/Coward for
consideration. They are a Denton firm that could respond quickly to our
needs. They have guaranteed a $64,000 utility savings on our current system
which will allow the City to go out and sell bonds that would be paid back
annually with that $64,000 savings. It would take approximately 8-10 years to
pay back the principal and interest.

resulting from any deductible provisions, corridor or self-insured retention
conditions of the policy or policies shall remain with the Contractor. The

Provide the necessary controls and interlocks, to automatically
operate the existing airhandler on either low or high speed
operation, depending upon the building cooling/heating load.
Operation at low speed, with a minimum cooling load, enhances
latent cooling capacity, and lessens energy consumption due to
lower fan horsepower usage.
Existing operation requires a manual change-over from low speed
to high speed, by a switch, located in the mechanical room.
