Mayor and Council Communication
COUNCIL ACTION: Approved on 11/1/2005
DATE: Tuesday, November 01, 2005
LOG NAME: 20FWCAC REFERENCE NO.: **C-21113
SUBJECT:
Authorize Execution of Contract with Basharkah Engineering Incorporated for the Design of
Improvements to the HeatingNentilation/Air Conditioning System at the Fort Worth Community Arts
Center
RECOMMENDATION:
It is recommended that the City Council authorize the City Manager to execute a contract in the amount of
$93,000 with Basharkah Engineering Incorporated (BEI) for the design of improvements to the
Heating/Ventilation/Air Conditioning (HVAC) system at the Fort Worth Community Arts Center.
DISCUSSION:
The lease agreement between the City and the Arts Council of Fort Worth and Tarrant County for the Fort
Worth Community Arts Center facility states that the Arts Council may petition the City to fund needed
repairs to major building systems. The facility's HVAC system is in urgent need of major upgrades. The
Arts Council has petitioned the City to fund the repairs.
On December 9, 2003, (M&C G-14190) Council authorized the use of $131,500 from the Capital Projects
Reserve Fund for the following improvements to the Fort Worth Community Arts Center (FWCAC):
- $30,000 to replace a cooling tower
- $100,000 to replace a chiller
- $1,500 to replace a heat pump
In planning the replacement of the three components of the HVAC system mentioned above it was
determined that a more prudent investment of the allocated funding would be as follows:
- $25,000 for maintenance and repair to existing HVAC system components to increase short-term system
reliability;
- $20,000 for a full engineering evaluation of the entire HVAC system to recommend a comprehensive
upgrade project; and
- $86,500 for engineering design of the comprehensive project.
Staffs intention to use the allocated funding as described above was communicated to Council on
December 21, 2004 (Informal Report No. 8648). The maintenance and repair work has been completed at
a cost of $20,500. BEI was contracted in April 2005 to perform the engineering evaluation for a fee of
$12,000. BEI completed the engineering evaluation in June 2005. BEI estimates the cost of the
recommended improvements at $1,100,000. It is possible to phase the work based on priorities and spread
the cost of these capital upgrades over several years. All of the systems recommended for upgrade,
however, have components that are well past their expected life and are subject to failure at any time.
No funding has been identified at this time for the execution of the needed upgrades. Proceeding with the
design at this time, while alternatives for financing the project are being evaluated, will help expedite the
ultimate correction of the HVAC system problems. BEI's work on the engineering evaluation was
Logname: 03HRS01 Page 1 of 2
outstanding. Based on that performance and its familiarity with the facility, City staff recommends that BEI
be engaged to design the project. BEI's fee proposal of$93,000 for this project is considered to be fair and
reasonable.
BEI is in compliance with the City's M/WBE ordinance by committing to 14% M/WBE participation on this
project. The MWBE goal for this project is 25%.
The Fort Worth Community Arts Center is located in COUNCIL DISTRICT 7 but serves all Fort Worth
residents.
FISCAL INFORMATION/CERTIFICATION:
The Finance Director certifies that funds are available in the current capital budget, as appropriated, of the
Specially Funded Capital Projects Fund.

SURVEY OF EXISTING MECHANICAL SYSTEMS — COMMUNITY ART CETER
FORT WORTH, TEXAS
EXECUTIVE SUMMARY
In spring 2005, Architectural Service Division, City of Fort Worth requested that Basharkhah
Engineering, Inc. conduct an on-site investigative survey to review existing conditions and to
prepare an investigative survey/cost estimate for replacement of the HVAC systems of the
Community Art Center (CAC). The purpose of the survey is to advise the City of Fort Worth on
the general conditions of the HVAC systems and to develop a cost estimate for the replacement
project. This information is to be utilized by the City of Fort Worth in finalizing considerations
regarding this facility.
The on-site survey was conducted based on the synthesis of site observations, review of available
record drawings, and discussions with owner's representative. The CAC contains approximately
86,000 SF and consists of two distinct structures, the Scott Theater and the Art Museum. The
building is generally in fair condition; however, observations of the facility were limited to the
issues related to the scope of this report.
HVAC systems for the building are comprised of air handlers in the mechanical room, supplied by
the chiller/boiler central plant. The HVAC system was built in three separate phases that
correspond with the 1955 Art Museum construction, the 1964 Scott Theater construction and the
1974 Art Museum renovationladdition.
Despite being well maintained, the central plant system has surpassed its life expectancy. The air
handlers have rusting problems at panel joints and corners. The system is not using its chemical
treatment system but the major control functions are operating.
Three alternative HVAC systems were considered as replacement options for the HVAC system at
the Fort Worth Community Art Center. These systems were compared in terms of installation
cost, energy efficiency, ease of maintenance, constructability, controllability, construction phasing
and current code requirements. The alternatives considered include installing a new four pipe
hydronic system, installing a two pipe water source heat pump system and installing a complete
DX system.
Based on observations and analysis of conditions of the Fort Worth Community Arts Center we
recommend replacing the existing HVAC system at the facility with a new four pipe hydronic
system. The reasons for recommending the four pipe hydronic system over the other alternatives
primarily revolve around having to install within an existing facility. The four pipe hydronic
alternative most closely matches the configuration of the existing system and would meet less
resistance and difficulty in terms of aesthetics approval and space limitations.

SURVEY OF EXISTING IVIECHANICAL SYS-rEIVIS — COMMUNITY ART CETER
FORT WORTH, TEXAS
The survey and this report should not be interpreted as an exhaustive survey of existing conditions,
all deficiencies, and/or code compliance of each system or structure. The discussion contained
within the report represents our professional opinions based on our experience and observations,
and do not imply any warranty by our firm and the Team.
GENERAL BACKGROUND
The existing CAC is located in the Fort Worth Cultural District and occupies a city block. The
CAC contains approximately 86,000 SF and consists of two distinct structures, the Scott Theater
and the Art Museum. The two structures are linked at ground level through the lobby and below
ground through a tunnel.
The CAC was built in three phases. The original 28,760 SF Art Museum, built in 1955, had a
basement, a first floor and a second floor. The 33,600 SF Performing Arts building, built in 1964
and now called Scott Theater had a subbasement, a lower floor, a main floor and an upper floor.
The 24,000 SF Art Museum addition was built in 1974 and added to all three floors of the
original Art Museum.
The site is approximately four acres in size. The Art Museum is basically rectangular in shape and
is located to the south of the square shaped Scott Theater. The Art Museum is currently being
leased to the Fort Worth Arts Council which uses some of the building as administrative offices
and subleases out other spaces for exhibits and special events. The Scott Theater still hosts
performances and special events.
The building's type of construction appears to be a concrete structure at the Basement level and
concrete and steel composite structure above. The building is not fully fire-sprinklered. HVAC
systems are comprised of floor mounted air handlers in the separate mechanical rooms and
suspended units in other spaces supplied by the chiller/boiler central plant.

OBSERVATIONS/ANALYSIS
The building is generally in fair condition; however, observations of the facility were limited to the
issues related to the scope of this report.
Civil
For purposes of this report, the east side of the building is the front and faces Gendy Street.
Lancaster Avenue is on the north along with the dock entrance for the Scott Theater building. The
dock for the Art Museum, along with a ramp down to the dock level, is on the west side of the
building. On the south side is an undeveloped block used for temporary parking. It appears the
area south of the facility is unused city property while the streets to the west, north and east are be
public right of ways.
-6-
SURVEY OF EXISTING MECHANICAL SYSTEMS — COMMUNITY ART CETER
FORT WORTH, TEXAS
Most of the utilities are in Montgomery Street to the west including gas, water, electrical and
telephone facilities. Sanitary Sewer is located to the east under Gendy Street.
Art Museum Basement
The basement areas appear to be in a fair to good condition. The basement consists of a series of
large rooms, connected together. Currently, most of the basement level is being used as storage
for the Fort Worth Arts Council. The basement is connected to the first floor via three stairs and
two elevators; one stair and one elevator were installed during the 1981 addition.
Other spaces located in the basement include the central plant and three mechanical rooms. The
central consisting of the original 1955 steam boiler and chiller, a hot water boiler and chiller added
during the 1964 Scott Theater addition and a hot water boiler and chiller added during the 1974
Art Museum addition. One of the mechanical rooms contain the original four 1955 air handling
units, another contains a large mutizone air handling unit installed during the 1974 addition and the
third contains a small single zone air handling unit also installed during the 1974 addition.
The small air handling unit installed during the 1974 addition serves the vault rooms at the east end
of the Basement but all the other air handling units are ducted to the floors above. Outside air is
brought in through the Basement walls. Concrete trenches are provided to bring in outside air for
those air handling units with exterior walls below grade.
The central plant room is separated from the mechanical room with the four air handling units by a
plywood wall. The dock entrance is at the southeast end of the basement, which is at the far end
away from the central plant. Even though the distance from the central plant to the dock entrance
is quite far, the corridors connecting the two are large enough to support replacement of the
central plant equipment without equipment disassembly.
Observations related to the basement are as follows:
• Concrete floors in the mechanical, electrical rooms and storage areas.
• According to 2002 Report, asbestos was found in the floor tile mastic in the Hall, in the tape
associated with duct insulation, in the insulation on the boiler and heat exchanger and in the
pipe insulation runs and fittings.

• Central plant equipment lacks adequate controls and appears to be inadequate for current
demands (continuous maintenance problems were reported).
• Reciprocating chillers had inadequate vibration isolation causing excessive ground vibration
and noise.
• Corrosion was evident on all piping, ductwork and air handling equipment. Oldest systems had
the worst corrosion evident. The worst corrosion evident included severely pitted piping and
holes in air handling units.
• Vapormisters, associated with the 1974 air handling units, were highly corroded and
inoperable. Ductwork at pipe penetrations of Vapormister systems were also highly corroded
and leaking air.
• Demolition of one gypboard framed wall would be required for removal of mechanical
equipment in central plant room.
Art Museum First Floor
The first floor areas appear to be in a fair to good condition. The first floor houses mostly large
exhibit areas with some small offices, some small storage rooms, a small kitchen, public restrooms
and the link to the Scott Theater. The first floor is connected to the second floor via four stairs
and two elevators; two stairs and one elevator were installed during the 1981 addition.
One small air handling unit serves the north stair of the 1974 addition. Ductwork from air
handling units in the basement pass through chases to enter the ceiling space of the first floor
except that ductwork from a second floor air handling unit serves to small offices. Most of the
ductwork from air handling units in the basement serves the fust floor, but, some of ductwork
from the large multizone unit serves the second floor of the 1974 addition.
Observations related to these first floor areas are as follows:
• According to 2002 Report, asbestos was found in the floor tile and black mastic in the Kitchen
and adjacent halls and in the original Art Museum Stair, in the surface texture and joint
compound associated with finished sheetrock walls throughout first floor and in the surface

orchestra elevator pit and the orchestra elevator pit. Currently, it is fairly empty and clean, with
limited amounts of mechanical equipment, materials and supplies. The sub-basement is connected
to the lower floor via two stairs.
Ductwork from one of the air handling unit in the mechanical room on the lower floor serves the
small rooms connected to the corridor. A heating/cooling hydronic terminal unit serves the Trap
Room.
Observations related to the sub-basement are as follows:
• Concrete floors in the mechanical, electrical rooms and storage areas.
• According to 2002 Report, asbestos was found in the pipe insulation runs and fittings and in
the button mastic associated with 1' x 1' applied ceiling tiles of a couple of the small rooms
connected to the corridor.
• Floor of orchestra elevator pit was covered with hydraulic fluid from recent elevator
equipment leak.
• Sub-basement had musty smell. It was reported that some tenants had complained of strong

above the upper floor roof.
Electrical
The existing electrical system at the CAC is a 120/208v, 3 phase, 4 wire system installed in the
original Art Museum in 1953. The system was revised and added on to in both the 1964
construction of Scott Theater and the 1974 Art Museum addition along with other minor
revisions/additions.
The existing electrical system is fed from a utility transformer located under the sidewalk of the
west first floor Art Museum entrance. Service is run from the primary transformer to a series of

main circuit breaker and main lug only switchboards in the main mechanical room via a 2000 amp
bus-duct.
Due to the age of the switchgear and the various additions and modifications to the switchgear(s)
there are several breakers that do not have amperage rating or identification as to what it is
serving. Based on conversations with maintenance personnel the gear appears to be functioning
properly with only a few breakers that occasionally are problematic.
In order to properly evaluate this switchgear for code violations and spare capacity a licensed
electrical contractor should be hired to identify breakers not labeled and trace unidentified circuits.
Upon evaluation of the electrical contractor's findings and selection of a mechanical system we
will then be able to further evaluate the switchgears capacity to accommodate the facility in the
future.
HVAC System
The building is only partially fire sprinklered. HVAC systems for the building are comprised of air
handlers in the mechanical room, supplied by the chiller/ boiler central plant. The CAC is expected
stay in partial operation with construction being phased in.
The HVAC system was built in three separate phases that correspond with the 1955 Art Museum
construction, the 1964 Scott Theater construction and the 1974 Art Museum renovation/addition.
All three phase incorporated water cooled chillers and induced draft cooling towers. The 1955
phase used a steam boiler coupled to a shell and tube heat exchanger for hydronic heating but the
1964 and 1974 phase both incorporated hot water boilers.
The 1955 design incorporated a two pipe hydronic system incorporating a 100 ton Trane
centrifugal chiller and a 860 MBH Commercial Steel gas fired steam boiler located in the basement
mechanical room of the Art Museum. The hydronic system is piped to four floor mounted single
zone air handling units on the basement floor of the Arts Museum and two single zone and one
multizone suspended air handling units on the second floor of the Art Museum. It was reported
that the steam boiler no longer operated and the centrifugal chiller was turned off during the
survey. Cooling during the survey was being provided by the chiller installed in 1964.
-15-
SURVEY OF EXISTING MECHANICAL SYSTEMS — COMMUNITY ART CETER
FORT WORTH, TEXAS
The 1964 design also incorporated a two pipe hydronic system, a 100 ton Carrier reciprocating
chiller and a 2,500 MBH Peerless gas fired hot water boiler located in the basement mechanical
room of the Art Museum. The hydronic system is piped to a suspended hydronic terminal unit in
the sub-basement of Scott Theater and four floor mounted single zone air handling units, three
suspended single zone air handling units and a suspended hydropic terminal unit on the lower floor
of the Scott Theater. The 1964 design included a DX split system air handling unit on the upper
floor of Scott Theater.
The 1974 design incorporated a four pipe hydronic system, a 60 ton Trane reciprocating chiller
and a 840 MBH Peerless gas fired hot water boiler located in the basement mechanical room of the
Art Museum. The hydronic system is piped to a floor mounted, multizone air handling unit and a
suspended, single zone air handling unit on the basement floor of the Art Museum, a suspended
single zone air handling unit on the first floor of the Art Museum and a floor mounted single air
handling unit on the second floor of the Art Museum. It was reported that chemical treatment was
longer being used to maintain the hydronic system because of loss of chemicals below ground from
a leak in piping leading to the second floor air handling unit.
The three systems share a common cooling tower system. The last upgrade to the underground
condenser water piping was made during the 1974 Art Museum addition. Of the two cooling
towers at the facility one is the 60 ton Marley unit installed 1974 but the other is 100 ton Marley
replacement unit installed in 1994.
The different hydronic systems have been interconnected in the mechanical room of the Art
Museum basement. Besides much of it being in deteriorated condition, the interconnections make
the piping in the mechanical room confusing and inefficient. This condition promotes
controllability concerns.
Despite being well maintained, the central plant system has surpassed its life expectancy. The air
handlers have rusting problems at panel joints and corners. The system is not using its chemical
treatment system but the major control functions are operating.

Applications provides Equipment Service Lifes. An Equipment Service Life is defined as the
median time during which a particular system or component remains in its original service
application and then is replaced. The Equipment Service Life given for cast iron boilers is 35

years, for diffusers, grilles and registers is 27 years, for fan-coil units is 20 years, for ductwork and
piping is 30 years, for centrifugal fans is 25 years, for water and DX coils is 20 years, for
reciprocating compressors is 20 years, for reciprocating packaged chillers is 20, for centrifugal
packaged chillers is 23, for galvanized metal cooling towers is 20 years, for molded insulation is
20 years, for blanket insulation is 20 years, for base mounted pumps is 20 years, for electric
motors is 18 years, for motor starters is 17 years, for electric transformers is 30 years, for
Pneumatic controls is 20 years and for pneumatic valve actuators is 20 years.
All of the HVAC equipment installed in 1955 with the original Art Museum has exceeded its
Equipment Service Life from 32 years for the electric motors to 15 years for the cast iron boiler.
All of the HVAC equipment installed in 1964 with the Scott Theater has exceeded its Equipment
Service Life from 23 years for the electric motors to 6 years for the cast iron boiler. All of the
HVAC equipment installed in 1974 with the Art Museum addition has exceeded its Equipment
Service Life from 15 years for the electric motors to 2 years for the for the grilles and diffusers
except that cast iron boiler has another 2 years before it reaches its Equipment Service Life. The
cooling tower installed in 1994 still has another 9 years before it reaches its Equipment Service
Life.
HVAC ALTERNATIVES CONSIDERED
Three alternative HVAC systems were considered as replacement options for the HVAC system at
the Fort Worth Community Art Center. These systems were compared in terms of installation
cost, energy efficiency, ease of maintenance, constructabUity, controllability, construction phasing
and current code requirements. The alternatives considered include installing a new four pipe
hydronic system, installing a two pipe water source heat pump system and installing a complete
DX system.
Some considerations affect all the alternatives. One of those considerations is ventilation rates.
Increasing the ventilation rates up to current code requirements would require larger equipment.
Another consideration that affects all alternatives is the asbestos in the building. It is expected that
removal of any concealed equipment would require asbestos remediation. For that reason
replacement of ductwork above ceilings was not considered as part of the alternatives.
A third consideration that affects all alternatives is the condition of the hydronic piping in the
building. Even if the wall thickness of the old pipe allows for continued use, the scaling that may
-17-

FORT WORTH, TEXAS
exist inside the pipe could have an adverse affect on the performance of the new systems. For this
reason all alternatives consider replacement or abandonment of existing hydronic piping.
A fourth consideration is that some of the existing structure is not very conducive to rooftop units.
For this reason split system DX air handling unit replacement was applied in the mechanical rooms
for the DX alternative. Split systems would still require heat rejection units on the roof.
A fifth consideration that affects all is controllability. In the not to distant past hydronic systems
had a clear controllability advantage over DX systems but with today's technology that advantage
is not as pronounced. Controllability advantages of the different alternatives were not included in
the considerations for this report.
Four Pipe Hydronic System
This system would include replacing the old cooling tower, chillers, boilers, pumps, air handling
units, controls, and piping. This alternative should include a complete direct digital control system
with a central monitoring station. This alternative should also include replacing the multizone air
handling units with variable air volume systems.
Advantages include the least amount of rework required on the electrical system, better energy
efficiency when compared to direct expansion equipment and new units would most likely to fit in
old mechanical rooms. Disadvantages are cost of extensive four pipe piping runs, installation
would be more disruptive that rooftop units, loss of space inside of facility for mechanical
equipment, higher maintenance capability requirements that packaged equipment, and it would not
be as practical to take advantage of energy efficiency increase associated with geothermal well as
could be done with water source heat pumps.
Two Pipe Water Source Heat Pump System
This system would include replacing the old cooling tower, boiler, pumps and piping but the
chillers would be demolished and not replaced and the air handling units would be replaced with
water source heat pumps. This alternative should include a complete direct digital control system
with a central monitoring station. This alternative should also include replacing the multizone air
handling units with variable air volume systems.
Advantages include the better energy efficiency when compared to direct expansion equipment,
additional energy efficiency increase possible if geothermal wells installed, that it requires only a
two pipe hydroruc loop and, without the chillers, less central space is required. Disadvantages are
cost of extensive two pipe piping runs, installation would be more disruptive than rooftop units,
loss of space inside of facility for mechanical equipment, larger air handling units won't fit as easily
in existing mechanical rooms, more compressors requiring more maintenance and repair than
chiller system, possible increased noise level in mechanical rooms due to local refrigeration
-18-
SURVEY OF EXISTING MECHANICAL SYSTEMS — COMMUNITY ART CETER

compressors, system can not use existing power feeders from main switchgear and higher
maintenance capability requirements than packaged equipment.
DX system
This system would replace all the hydronic heating and cooling with packaged direct expansion
cooling and gas fired furnace heating units. This alternative would benefit from a complete direct
digital control system with a central monitoring station but this is not as important as it is with
hydronic systems. This alternative should also include replacing the multizone air handling units
with variable air volume systems.
Advantages include the installation would take less time, would be less disruptive to facility, would
not require installation of as many separate components as with hydronic systems, air handling
units would fit in existing mechanical rooms, no central plant space required and less on-site
maintenance capabilities required than with hydronic systems. Disadvantages are direct expansion
would have higher energy costs than hydronic systems employing cooling towers or geothermal
wells, requirement to place heat rejection units on roof and at grade for each air handling unit
would not be as esthetically acceptable as the central plant configuration of hydronic systems and
more compressors requiring maintenance and repair than chiller system.

RECOMMENDATIONS
Based on observations and analysis of conditions of the Fort Worth Community Arts Center we
recommend replacing the existing HVAC system at the facility with a new four pipe hydronic
system. The reasons for recommending the four pipe hydronic system over the other alternatives
primarily revolve around having to install within an existing facility. The four pipe hydronic
alternative most closely matches the configuration of the existing system and would meet less
resistance and difficulty in terms of aesthetics approval and space limitations.
Even though the four pipe hydronic system carries the highest first cost it still is the most attractive
of the three options. The lower energy costs of the four pipe system are expected more than
compensate for the lower first cost of the DX system in the life cycle analysis. The difficulty that
could be encountered in installing the water source heat pump units in the existing mechanical
rooms presents a level of risk that weighs against the lower first cost.
The following are our recommendations in order of priority:
1. Replacecentral plant equipment and the HVAC systems associated with the original 1955
Art Museum construction.

Mayor and Council Communication
COUNCIL ACTION: Approved on 11/1/2005
DATE: Tuesday, November 01, 2005
LOG NAME: 20FWCAC REFERENCE NO.: **C-21113
SUBJECT:
Authorize Execution of Contract with Basharkah Engineering Incorporated for the Design of
Improvements to the HeatingNentilation/Air Conditioning System at the Fort Worth Community Arts
Center
RECOMMENDATION:
It is recommended that the City Council authorize the City Manager to execute a contract in the amount of
$93,000 with Basharkah Engineering Incorporated (BEI) for the design of improvements to the
Heating/Ventilation/Air Conditioning (HVAC) system at the Fort Worth Community Arts Center.
DISCUSSION:
The lease agreement between the City and the Arts Council of Fort Worth and Tarrant County for the Fort
Worth Community Arts Center facility states that the Arts Council may petition the City to fund needed
repairs to major building systems. The facility's HVAC system is in urgent need of major upgrades. The
Arts Council has petitioned the City to fund the repairs.
On December 9, 2003, (M&C G-14190) Council authorized the use of $131,500 from the Capital Projects
Reserve Fund for the following improvements to the Fort Worth Community Arts Center (FWCAC):
- $30,000 to replace a cooling tower
- $100,000 to replace a chiller
- $1,500 to replace a heat pump
In planning the replacement of the three components of the HVAC system mentioned above it was
determined that a more prudent investment of the allocated funding would be as follows:
- $25,000 for maintenance and repair to existing HVAC system components to increase short-term system
reliability;
- $20,000 for a full engineering evaluation of the entire HVAC system to recommend a comprehensive
upgrade project; and
- $86,500 for engineering design of the comprehensive project.
Staffs intention to use the allocated funding as described above was communicated to Council on
December 21, 2004 (Informal Report No. 8648). The maintenance and repair work has been completed at
a cost of $20,500. BEI was contracted in April 2005 to perform the engineering evaluation for a fee of
$12,000. BEI completed the engineering evaluation in June 2005. BEI estimates the cost of the
recommended improvements at $1,100,000. It is possible to phase the work based on priorities and spread
the cost of these capital upgrades over several years. All of the systems recommended for upgrade,
however, have components that are well past their expected life and are subject to failure at any time.
No funding has been identified at this time for the execution of the needed upgrades. Pr7elo�,'6xpedite

outstanding. Based on that performance and its familiarity with the facility, City staff recommends that BEI
be engaged to design the project. BEI's fee proposal of $93,000 for this project is considered to be fair and
reasonable.
BEI is in compliance with the City's M/WBE ordinance by committing to 14% M/WBE participation on this
project. The MWBE goal for this project is 25%.
The Fort Worth Community Arts Center is located in COUNCIL DISTRICT 7 but serves all Fort Worth
residents.
