When Mark Kent
passed by a vacant brick building located in downtown Greenville, SC,
he didn’t just see prospective commercial property; he also saw an
opportunity to restore a piece of the past.
This turn-of-the-century building is located in a historic district
of Greenville surrounded by new high-rises. It features brick and
mortar construction with heart pine beams. The floors are heart pine
tongue-and-groove with hardwood overlay.
Listed on the National Historical Registry, the property has gone
through several incarnations, beginning as The American Cigar Factory,
where hand-rolled cigars were produced. After the Depression, the
building housed several cut and sew operations, including manufacturers
of military uniforms, men’s dress shirts, children’s apparel, and most
recently, soccer uniforms made by sportswear manufacturer Umbro. When
Umbro sold its U.S. operations, the building became vacant.
Kent, owner of the textile firm Kent Manufacturing, saw this
location as ideal for office, retail, and restaurant space and wanted
to restore the building’s interior to its original glory. Renovation of
the building, however, was no easy task. There were multiple coats of
lead-based paint covering the brick and woodwork, requiring extensive
abatement. Also, city codes required the addition of a second stairwell
and more restrooms.
Keeping with the building’s turn-of-the-century look, Kent added a
tower that matched the original design, as well as an elaborate glass
link system between the two buildings with connecting bridges
constructed of wrought-iron steel.
Kent’s concern with aesthetics, however, wasn’t limited to
architectural design; he also wanted a mechanical system that would
keep tenants comfortable and not detract from the beauty of the
building’s interior and exterior.
Since a special system requires a special contractor, Tuck &
Howell was brought on board the project by general contractor Trey
McCraw of McCraw & Associates. The company is led by Jerry Tuck,
who is widely recognized for his ability to work with period retrofits
and who has been involved in the system design for many historic
structures in downtown Greenville.
Furthermore, the two companies had completed several historic
Design/Build jobs together, and Kent was already familiar with Tuck
& Howell’s work. "I was quite pleased with the work they had done
in my home," Kent says. "I saw no reason not to use them again for this
project."
Having clients as both residential and commercial customers is
nothing new for Tuck & Howell. According to Senior Project Manager
B.C. "Clay" Livingston, the company started out as a residential and
service organization, and then branched out into commercial and some
industrial work around 15 years ago. "Despite the growth of this
division, we have maintained a strong residential presence," Livingston
states. "We have never abandoned one client to get another."
In fact, it’s often from this residential base (25% of its
business) that the firm finds much of its commercial business.
Livingston adds, "It’s not unusual for us to have done work in a
physician’s home and then later be referred for a project at a medical
facility. We were honored to be chosen for this project and thrilled to
have the opportunity to help Mark Kent bring this building back to
life."
Aesthetics vs. Comfort/Control
Designing the mechanical system for the Kent Building presented
Tuck & Howell with the challenge of reconciling limited space with
the need for comfort and control, as well as maintaining the integrity
of the building. Livingston recounts, "The installation in this
building presented challenges running the gamut of our industry.
Equipment type, location, and installation cost were all important.
Furthermore, the final design had to fit small, leasable spaces and the
ease of future tenant moves into the overall plan."
Tuck & Howell offered Kent several mechanical system options,
ranging from a four-pipe boiler and chiller plant to water source heat
pumps to gas-fired rooftop units. According to Livingston, rooftop
units were out of the question, since the building features a huge
skylight. A chiller would have detracted from the building’s exterior,
and a water tower would have produced steam visible during the winter.
With all these considerations in mind, Tuck & Howell designed
and installed a two-pipe system with a boiler, coupled with hot water
coils on the air handlers for heat and a DX system for cooling.
Livingston states that since the historic requirements of the building
precluded the use of proper insulation, the boiler was chosen for its
ability to provide quickly available heat and high leaving air
temperature. "DX cooling was used," he adds, "because of its low
installation cost and easy system dedicated zoning."
For controls, Tuck & Howell installed a building management
system with panels located on each level of the building and individual
zone sensors located within the conditioned spaces.
Careful Attention to Detail
Because of the open structure of the Kent Building, the system’s
ductwork had to be visibly installed. Livingston comments, "The owner
was very conscious of maintaining the look of the original brick and
stained heart pine framing timbers. To do so, we worked with our
engineering firm to design around oval paint-grip duct. The oval duct
was used to maintain ceiling height, and the flat black painted duct
blends very well into the surroundings."
"To further camouflage the ductwork," Livingston says, "the VAV
dampers are turned so as to have low visibility. Control wiring for the
systems is run along the top of the duct and cannot be seen from the
floor, with the control panels mounted in each equipment room."
Furthermore, the Design/Build team’s attention to aesthetic detail
wasn’t limited to the building itself, but extends to the indoor
mechanical rooms. James "Jamie" Porterfield, staff engineer/junior
project manager for Tuck & Howell, comments that these "aren’t your
typical boiler rooms." Instead the rooms, which open directly into
occupied space, are extravagant and boast stained wooden doors and
ceramic floors. "They are a showplace for our work," Livingston adds.
A Separate Space
In addition to the principal system, Tuck & Howell also had to
address the heating needs of the new elevator/rest-room tower, which
presented its own challenge. According to Livingston, "This area has a
very open look and limited framed walls. So once again, we needed a
system that fit into the space available and didn’t disrupt the look of
the area."
To condition this space, Tuck & Howell chose split heat pumps,
which met the common conditioning requirements and limited equipment
space within the tower.
The duct for the tower consists of a riser from basement-mounted
air handlers to the upper levels with sidewall penetrations for the
elevator lobbies. The restrooms are conditioned by the same riser with
duct in soffits over the lavatories.
Creative Solutions
Another challenge facing Tuck & Howell was where and how to
unobtrusively install the exterior equipment. As a solution, the
project’s architect, the Pazdan-Smith Group, designed an outdoor
equipment yard featuring the same brick and period design as the
original building, which includes crossbuck wooden gates matching the
building’s motif.
Inside the yard, Tuck & Howell installed outdoor boilers and
the condensing units. The refrigerant piping was tunneled from the
courtyard where the equipment was located to the inside of the
building. Livingston comments that this was no easy task, as "extreme
coordination among all trades was required due to the very limited
space for building entry."
In addition, the team learned the importance of including extra
piping when running a tunnel. Porterfield says, "We ran an extra set
(of piping) for future use, and discovered that we did, indeed, need
the extra piping. Once you begin running the pipe through, you can’t go
back and start again."
Kent comments on how pleased he is with the equipment yard: "Since
the building is located next to a residential zone, I was concerned
about the potential noise generated from the equipment and complaints
from my residential neighbors. This hasn’t been the case at all. In
addition, with the equipment being low-profile and well-hidden, you
can’t even see the units unless you’re above them."
He’s also pleased with Tuck & Howell’s creative solution of
introducing outside air into the building. Since Kent didn’t want any
exterior sidewall penetrations for air handling units, the team removed
an old fire escape on the rear of the building and installed faux
balconies at each of the unused doors. The doors were rendered
inoperable and matching colored grilles were installed. The outside air
was then ducted from these grilles to air handling units. As a result,
this solution not only provides tenants with fresh air, but the
balconies lend a New Orleans touch to the building.
A Job Well-Done & On-Time
The successful completion of this project not only required hard
work and creativity, but a seamless coordination of the Design/Build
team’s efforts from start to finish.
"The abatement process for the building was very time-consuming and
resulted in a tight schedule for the installation," Livingston states.
"However, we were able to meet the schedule by being very creative with
personnel assignments."
This included maintaining an after-hours presence in the service
sector. Tuck & Howell’s weekend and after-hours service personnel
were required to report to work at the job and take service calls from
the jobsite. Upon completion of the call, the technician would return
to the job. "The refrigerant piping was completed by this method. In
addition, we teamed with a local piping firm to handle the
boiler-to-water coil piping," Livingston says.
"Our on-call service personnel completed the control wiring with a
minimum of overtime. We also handled our own control wiring in house,
which allowed us to mesh with the ongoing construction process," he
adds.
Livingston credits Tuck with how smoothly this process went. "Jerry
put a tremendous amount of time into the project and visited the
jobsite almost daily for many weeks. The job could have never gone as
well without his assistance directing the field personnel," he states.
Also, Kent was presenting space to potential tenants during the
installation, which meant the engineering firm had to be in a
continuous state of redesign for tenant spaces. "Our engineering firm,
LeBlanc & Welch, Inc., proved to be well up to the challenge and
kept changes flowing without delay," Livingston says. He also
attributes the project’s success to the architectural team of Joe
Pazdan and Lisa Lanni. "Not only were Joe and Lisa very cooperative in
allocating equipment spaces and chases, but they were right there when
the day-to-day challenges were taking place."
Commissioning & Beyond
Tuck & Howell’s own well-trained and experienced staff are
handling the start-up and balancing. In fact, the balancing will be
ongoing since the building is still in the process of being occupied.
According to Kent, the system is functioning beautifully, and hasn’t
required a single service call. He has contracted with Tuck &
Howell to handle all aspects of the system, and is interested in the
company designing a system for a 10-story historic building he’s
currently renovating.
As for Tuck & Howell, the firm looks forward to again bringing another piece of the past into the future.
