A large part of the overall effect was the
use of projector lights that were precisely aimed using lasers to
reflect the beams off of mirrors in the top of the atrium to reach
specific points on the floor. The final touch to achieve the architect’s
vision of the structure was the installation of a complex dimming
and lighting control system that is programmed to operate the lights
in different sequences and levels of brightness to provide maximum
effect while adjusting for the ever-changing levels of ambient conditions.

The original building was built in 1917
and it was necessary to maintain the historical value of the building
while providing all of the upgrades. The chandeliers in the ballroom
and some of the lights fixtures in the lobby are antiques that were
retrofitted and installed by the craftsmen; all of the other fixtures
are new. From the spa to the restaurant to the roof top bar and every
floor in between every light fixture was installed with the utmost
concerned by the most skilled craftsman.

Originally constructed in 1820, the DC Court
of Appeals building is one of the oldest buildings in Washington,
DC. The electrical work had to be laid out on the existing plaster
and brick structure which was then removed and then the electrical
rough-in installed. One of the most impressive aspects of this project
is the amount of work that was put in which is now concealed behind
plaster walls finished to look as they have for over a century. The
project consisted of over 110 different fixture types with multiple
custom colors and finishes from numerous different manufacturers.
The project is unique in the fact that the fixtures installed ranged
from art deco inspired chandeliers to refurbished historic wall sconces
to custom replications of historic light fixtures. Many fixtures were
removed and refurbished to their original condition. A number of fixtures
were replications of originals. The project also had three dimming
systems; two for the courtrooms and one for the site lighting. The
project also had an energy management system for lighting.

The significant attributes to this project
includes house lighting that are incorporated in block walls, handrail
lights that were custom-made to fit around the egress areas, aisle
lighting that was incorporated into concrete. The theater outlets
for stage lighting are roughed in block walls powered by the main
dimmer boards. The lighting control system includes multiple switches
located in each control room for each theater. There is a section
in the theater that has removable seating where the mixing station
floor box is located for the control of the theater’s AV system.
The AV/microphone speakers are installed on the balcony level. The
upper level is provided with all the systems that are installed on
the lower level with the exception of floor boxes. A theater rigging
control for light battens were also installed. The design’s
objective was to have the conduit in the theater accentuate the steel
structures and have the light fixtures and theater lights that are
mounted on catwalk rails be the focal point of the theater.

In this project, all lighting, power and
controls were installed in conduit and compression fittings. The schedule
and noise level was compression and access to the job site was challenging
as no trades were able to use elevators for manpower and materials.
The CNMC project consisted of over 25 different styles of specialty
light fixture styles, ranging from fluorescent 2 x 4 lighting in patient
areas to the complicated LED panels, tubing and power color core LED’s
in the lobbies. A typical patient room consisted of 14 light fixtures.
Some of these fixtures were wall mounted in drywall while others were
ceiling. Multiple system and voltages were intertwined to provide
lighting on critical, emergency and normal power simultaneously to
the patient headwall unit. The headwall unit controls the four function
lights over the patient bed; three of which interface with the patient
pillow speaker for optimum patient lighting comfort. The lobbies were
constructed with low voltage lighting. Color changing LED’s
mounted in custom boxes anchor the elevator lobby. LED panels in the
ceiling portray the night sky as you exit the elevators.

unique because they were built at different times using equipment
from several different manufacturers who used proprietary design criteria.
Additionally, the new equipment was integrated with existing equipment
in the rest of the system. Truland Walker Seal JV rebuilt the substations
without disrupting daily service by coordinating with WMATA and PEPCO
and Dominion Power and performing most of the work during the four
to five hours Metro was not in service. Crews worked in difficult
conditions often deep underground or beneath major traffic arteries.

The key to the project was to determine
how to install 9,6000 feet of feeder conduit, 300 feet of 2500-Amp
copper busway and 200 feet of 5000-Amp copper buss way, HVAC ductwork,
pre-action fire suppression system and a fire detection systems in
a ceiling space of three and half feet. Freestate Electrical installed
the electrical design for the new UPS which consists of three incoming
15 KVA services to a main distribution switchgear. The switchgear
consists of an A side main and B side main. The center main is connected
via tie breakers to the A and B side of the gear achieving one common
bus. There are two generator paralleling gears, PSG-A and PSG-B. Each
gear consists of three sets of electrical bus—a No-Break bus,
a Short-Break bus and a Common bus connecting the two choke reactors
at either end of the PSG boards. Both PSG boards are connected via
a 5,000 Amp cross link bus way. The four choke reactors are fed from
the utility MDS gear via a 2,500 Amp bus way and from two Continuous
Power System (CPS). The CPS units are synchronous condenser/ ac-motor
unit which supply a leading power factor to compensate for the potential
lagging power factor on the utility. There are four 3-source Digital
Static Transfer Switches. Two sources are from the PSG-A, B boards
and the third is from the utility board. The load side feeds distribution
boards T1-T4.

Many aspects of this project made it particularly
difficult and the work exceptional. All power wiring was designed
to be run overhead but due to weight limitations, it was necessary
to install an underground duct bank system. This entailed saw cutting
and excavating the inside of the existing data facility. The duct
bank system was design in the field including intercepting existing
medium voltage feeders. Natelco performed five levels of commissioning
including factory witness testing in Germany. Crews installed a three
tier battery rack system which consisted of 369 battery jars to be
unloaded, stored and hoisted up on the racks. The most difficult part
of the job was intercepting three critical load buss ways over the
existing data center floor without loss of critical load or redundancy.

to new construction projects, so the system was replaced while the
building was fully occupied. Freestate teamed with Alarm Tech Solutions
to replace the old system on a floor by floor basis. Crews changed
over the controls and status of all of the components of the smoke
control and stair pressurization systems as well as all initiating
devices while reusing as much circuit wiring as possible. New riser
wiring was installed in existing conduits to facilitate a changeover.
New remote power expander panels and amplifier cabinets were installed.
After the emergency replacement of existing fire alarm and emergency
communications system, Freestate and Alarm Tech went on to do the
fire alarm, gas detection and emergency communications for the Health

David Allen started tile work in the NE core with a mockup of one
bathroom for the entire project team’s review. David Allen then
worked the NE core down to completion and moved counterclockwise to
the SE core. David Allen worked through many obstacles, the largest
being the weather. Without a complete curtainwall, David Allen worked
in confined bathrooms with small heaters so that the mastic and grout
could set. As the leaders driving the bathroom schedule, David Allen
overcame the weather as well as leveling challenges and existing conditions

even through they were made of two different materials. The epoxy
terrazzo flooring consists of alternating strips of two colors through
the atrium lobby. The pre-cast treads installed as the feature stair
were cast with a weld plate of the bottom and were welded to the steel
tubes that service on the spine of the stair. They do not sit in a
pan like most of these types of installation. The installation of
the treads provide to be especially difficult when the tubes deflected
more than expected, but David Allen worked tirelessly to deliver a
breathtaking “wow” moment when you enter the atrium. This

space. Considerations were made to create a consistent floor height
as well as transition to an historic hallway between the bakery and
trattoria. Ward Ceramic Tile installed a mud bed under each type of
floor tailoring the mixture to the thickness and type of material
being used. Various flashing agents and latex additives were used
to create the necessary height and slope of the tile substrate for
tile installation. The types of tiles specified in the project included
ceramic, stone, encaustic and marble. Oval link stone mosaic tile
installed in the bakery was custom from China. Encaustic tile installed
throughout the trattoria and bakery was specified in a variety of
colors and patterns and was custom from Mexico. A unique pattern of
crackle glazed subway tile was installed in the bakery and brick colored
quarry paver mosaic was installed on the large pizza oven. To ensure
the correct patterns were achieved, nock ups were prepared daily and
became a pivotal part of the title installation process. The patterns
required a remarkable amount of prep work and lay out to ensure the

The Tyser Tower Renovation and Expansion
project is a 66,000 square-foot addition and complete renovation of
the 33,000 square-foot Tyser Tower, located at University of Maryland’s
(UMD) Byrd Stadium. One of UMD’s major stipulations was a high-quality
installation of tile in the restrooms throughout the building to eliminate
minor flaws common in tile installation—small slivers of tile
in the corners, tiles that are not perfectly square, grout joints
that are not uniform, and floor drains placed randomly in the floor.
David Allen worked to extremely tight tolerances during the tile installation
while meeting a demanding schedule. Public bathrooms include a cross
tile, manufactured by David Allen, with the Terps logo, while suite
bathrooms feature a red glass mosaic pattern. To distinguish the President’s
Suite, the bathroom follows a black and red granite scheme and the
water jet was produced in Atlanta and numbered for installation. This
glass-like pattern required minimal grout joints for installation.
To eliminate drain location problems, structural floor slabs were
constructed using two-foot square opening at the planned location
of each drain. As final drain locations were identified, David Allen
set them to fall within the tile pattern, which took considerable
time and effort. The end result is well above industry standards.

From behind the walls of the building to
the imposing atrium lobby, exceptional care and craftsmanship went
into constructing this high-end renovation of Crystal Plaza II. Much
of what sets this project apart is the work provided by Roman Mosaic
and Tile Company who installed epoxy and custom precast terrazzo flooring
throughout the lobby. Roman Mosaic overcame many unique obstacles,
from installing the spiral floor pattern layout based solely on a
rendering (no dimensioned plans), to extensive sand-fill to repair
slab conditions for the existing 40-year-old floors. Most notable
was the installation of the custom precast terrazzo on the lobby’s
grand staircase. Due to complex curves, shapes and tight dimensional
requirements, each piece had to be custom cast, cut and carefully
placed. In addition, the precast terrazzo had to interface with a
custom, curved-glass railing, which required multiple stages of installation
and extensive coordination.

The work at Georgetown Preparatory School
New Learning Center consisted of the renovation of the existing field
house and a new building addition. A 44-foot by 5-foot skylight was
cut into the existing roof roughly 28 feet above the new finished
floor in the new Library. Capitol Drywall installed new multi-tiered
ACT, wood and sound panel and drywall ceilings. The drywall installation
and finishing posed significant challenges. The new ceiling slopes
up on four sides from an elevation of 16 feet. In addition, the ceiling
was turned on a 10 degree angle to the East-West axis of the building
order to align with the architectural elements that carry through
both the new and renovation work. Capitol Drywall performed layout
on the concrete slab and transferred the layout up to multiple elevations.
They then determined how to coordinate the required ceiling framing
members with the existing steel cross bracing and trusses. Finally,
due to the significant exposure to sunlight throughout the day the
finish work had to be of the highest quality to make the gypsum board
joints, screw heads and other imperfections disappear.

The renovation and expansion of the Arena
Stages performing arts campus in Southwest DC covered 200,000 square
feet and took 29 months. It included the creation of a new performance
arts space, the Cradle Theater, and extensive improvements to the
existing buildings. The new Arena Stage will be a largely transparent
structure under a prominent cantilevered roof. The sleek and amorphous
roof design creates the illusion of wave-like movement. Using light
gauge framing, Cleveland Construction successfully executed the architect’s
vision for the roof overhang and terrace soffit. The overhang undulates
as it wraps around the perimeter of the building. In the northwest
corner, it expands over the terrace and out to a cantilevered point.
To create this effect, the framing in the northwest corner had to
be installed to accommodate the deflections in the cantilevered roof.
The expansive soffit and sloping corner is interrupted by control
joints designed for movement and aesthetics. Cleveland Construction
worked off lifts to get to the overhang and soffit and will use lifts
to finish the soffit with acrylic stucco. The geometry made layout
and framing difficult, but limited access to the overhang made the
work even more complicated.

S. DiGregorio & Son furnished and installed
drywall throughout Capital Cove, including the main lobby, pool area
and sales office. The scope of work consisted of structural and interior
studs, dense glass, gypsum wallboard walls and ceilings. The results
are flawlessly finished, long corridors with chair rail and light
fixtures smoothly spanning more than 300 feet in length. The drywall
is perfectly aligned with all joints hidden from sight—evidence
of exceptional skill and attention to detail. The same seamless results
were accomplished with the ceilings in the indoor pool area, outdoor
breezeway and sales office. The ceilings were finished with a high-gloss
paint, which really shines a spotlight on the high-end results DiGregorio
delivered.

walls and ceilings and field painted the paint-grade millwork. The
color and material schedule for the project had 174 paint types listed.
All of the guestroom walls required multi-color wall treatment that
varied depending on the floor and scheme. Everything, including device
cover plates, was painted. There are 99 guest rooms in the hotel with
24 different colors that were applied in various arrangements depending
on the room scheme. These colors, and the 12 new colors for the public
areas on the basement and first floors, created a complicated web
of colors and paint types for the painter to keep track of. NLP successfully
accomplished the task with no errors due to wrong paint or color application.

The concept of this project was to completely
renovate an existing space and create a truly state of the art audio
visual recording, editing and production facility with a visually
refined atmosphere to compliment the technical precision of the space.
Throughout the building, various colors of Armourcoat plaster were
used to create a hand-trowel Venetian marble and a dragged finish
to this end. The artisans seamlessly completed a continuous wall-
approximately 200 feet long by nine feet tall- in six bands of finish,
three dragged and three Venetian. This area spanned two entrance lobbies
and the main corridor of the building and included many 90 degree
turns to complicate the work. In addition, a dragged Armourcoat finish,
nine feet wide by 20 feet tall was used in the main stairwell landing
which incorporated a polished TPI logo, a particular accomplishment
with all of the acute edges and size of the logo.

garage. Central to the site is the historic “Pope Building”
positioned adjacent to the new building. Miller Painting refreshed
and repaired aged wall finishes with modern products and techniques
while maintaining the building’s historic ambiance. Miller Painting
instituted a second shift from 3pm to 12am. Thanks to Miller Painting’s
efforts, more than 118 owner-initiated modifications without impact
to the schedule. The two underground garage levels were striped and
sealed, walls were painted using laser levels and fire suppression
systems were color-coded. Each of the eight tenant-occupied levels
included application of traditional paints, spray-applied Polymyx
and vinyl wall coverings. The focal point of the new addition is the
main lobby, where two different faux finishes were applied. The first
seamlessly imitates the Andes Gray marble on the floor and columns.
The second replicates a wall covering that was originally found within
the Pope Building. All paints, primers, adhesives and sealers were
low-VOC, enabling the project to work toward LEED Gold certification.

hand chiseled stones from Western Maryland. Each piece was selected
to provide a consistently random appearance. Special care was made
to limit the amount of split face on exterior to maximize the percentage
of natural stone edges. Therefore, a high amount of stone was rejected
to maintain this level of quality control while providing a “slapped-together”
look. Lorton used a new, innovative corrugated weep drainage system
and an advanced stone tie system resided behind the rubble stone.
Lorton’s designers created 3-D models to determine coordinating
the multiple radii and slopes that existed in the exterior granite
hardscapes, water feature and tied into the interior granite flooring

the heart of the HVAC system are located in a tight glass walled penthouse.
The building is conditioned by two massive Ventrol air handling units
utilizing new fan wall technology and concealed in roof mounted in
wells. The main two-level mechanical room includes two McQuay dual
compressor centrifugal chillers, nine base mounted pumps, UV disinfection
equipment, cartridge filtration and chemical treatment system. During
construction, the addition of a heat exchanger, pumps and associated
piping only added to complexity of the project. The limited space
required precise coordination and piping prefabrication. Of special
note was the sequencing of the equipment and pipe rigging because
there was limited staging area on the roof. The window of opportunity
was further restricted by the curtain wall construction. Care was
taken at all times to prevent damage to the unusual glass curtain
wall enclosing the penthouse.

is constructed using an intricate system of roof trusses, joists and
girders which are supported by 60-foot timber columns and architectural
concrete walls. The steel trusses range in length, up to 120 feet,
and along the perimeter of the structure the trusses are supported
by the timber columns. The perimeter of the roof is curved across
multiple radiuses. Steel rafters installed along the perimeter provide
the oscillating elevation changes which combined with the radiuses,
creates a wave-like illusion. Between timber columns, steel spandrel
trusses support a cable suspension system which supports the 45-foot
frameless window wall. The steel had to be erected to tolerances as
minimal as one-quarter inch in either direction. At the west end,
a large girder is installed which cantilevers out 65 feet, creating

consisted of 1 9/16-inch thick ceramic clay tile panels on the exterior
face with air space and mineral wool cavity insulation between the
panels and building substrate. Overlapping horizontal joints between
panels prevent driving rain from entering the cavity, yet allow air
flow upward within the cavity to assist in keeping it free of trapped
moisture and heat. This project incorporates over 11,000 body terra
cotta panels from the second floor up consisting of 11-inch, nominal
height flat panels of three separate colors and a ribbed panel profile
of a fourth color. These panels are installed in up to five-foot lengths.
In addition, over 1,500 glazed terra cotta panels are installed below
the second floor. The aluminum support system required a high degree
of layout and coordination with existing substrate and opening systems.
Calvert’s crews worked hard to ensure the proper spacing and
alignments for vertical joints in up to 70 feet of continuous run
and horizontal joints up to 125 feet of continuous run. Over 16,000
feet of horizontal aluminum framing and over 13,000 feet of vertical

entry level, 9th floor, “Sky Lobby”. Jefferson sat with
designers in the submittal process to ensure proper interpretation
of the designer’s intent and offered insights. For example,
during the show drawing process it was determined that the Pivoting
Wall Server would be too heavy if it was built with steel, so Jefferson
presented a design using an interior Trespa structure which was an
ideal substitution. For the elevator lobby, Jefferson installed stainless
steel wrapped base, lacquered MDF panels on the walls and ceiling
and SS fins that bordered the panels, drywall and elevator frames.
The Sky Lobby reception desk features the same Bendheim triple-paneled
laminated blue glass that can be found on the base building’s
“Street Lobby”. This glass is framed with custom SS channel
that houses a ¼-inch and ¼-inch glass blade. The desk
consisted of lacquered MDF panels, African Mohogany elements and a
Trend Q Stone countertop. Tables are made from bent aluminum panel,
colored 3form is attached by flush mounted SS standoffs. The wall
adjacent to the café seating also features back-painted glass
and a 3form backsplash. The conference room is bordered by ten foot
high swinging millwork doors which close and interlock together as
a continuous wall which is covered by fabric panels in the interior
of the room and locked in place with dust proof strikes. Jefferson
contributed to LEED certification by documenting the recycled content
materials and using low-VOC adhesives.

The atrium alone is reminiscent of a glass
cage. It includes a stone fountain with a glass entry leading to the
servery. The servery is all white glass panels with lacquer/stainless
steel cabinets and Corian tops which all comes together as one.

The elliptical wood wall in the atrium is
one of the most stunning design features of the Georgetown University
McDonough School of Business. The fire-rated wall follows the elliptical
curve of the storefront for four stories, and also follows a diagonal
line from top to bottom. Two species of wood veneer were used to create
a slight checkerboard feel to the wall. Detailing and fabricating
the wall took a lot of time and effort with astonishing results. This
unique design feature will wow all who enter this building. The high
quality craftsmanship is also apparent in the work on the curved classroom
desks and two-story sliding doors in the auditorium. This project
has been submitted for LEED Silver certification.
