Architectural Features:
The building is a 4 story steel frame building. The 1st floor has a branch
bank and the general space is for the public. The bank vault is located
in the SE corner of the building. The 2nd and 3rd floors are typical office
layout. There are large areas laid out for specific uses of the bank (i.e
insurance, loans, finance). The 4th floor is reserved for future plan layouts,
which are dependent on the growth of the company. There is an elevator bay,
containing two elevators, in the central core of the building. Stairs are
provided at the south and west ends of the building. One set of restrooms
are provided on each floor adjacent to the elevators in the center of the
building. On the 1st, 2nd, and 4th floors a kitchenette is provided which
is adjacent to the restrooms. There are two entrances; One on the south
end, and one on the north-east corner of the building, which is much more
grand of an entrance.

Building Envelope:
A typical exterior wall is as follows…
4” nominal masonry veneer, 1” air space, ½” glass
mat faced gypsum sheathing with a weather resistive barrier, 6” metal
studs @ 16” O.C., R-21 fiberglass batt insulation with vapor barrier
and 5/8 gypsum wallboard. The color of the brick veneer used to clad the
building envelope is cranberry velour. The Precast Concrete (used as an
architectural detail) is a limestone color with a smooth finish. Metal coping
is used as an accent which is to match the champagne aluminum curtain wall
and door systems. EIFS (exterior insulation finish system) is used near
the top of the building (4th floor) which is matched to the pre-cast color
(limestone) or a senergy metallic finish patina green (used on the soffit/fascia).
Large spandrel glass sections are used to envelope the staircases.
Roof System:
The roof system used is a built-up roof which is slightly sloped to the
different areas of the roof for draining purposes. Interior drainage is
provided so that the architectural façade will not be interrupted
by drain pipes. This built-up roofing system utilizes a stone ballast system
that sits upon ½” glass sheathing roof membrane, R20 roof insulation,
and 1½” 24k4 metal decking (typically). There are several roof
overhangs placed at the 2nd floor. These overhangs are above entrances and
various windows. The overhang roofs are sloped at 45º.

Primary Engineering Systems
Structural:
The foundation of the structure makes use of spread footings. The footings
are as small as 5’x 5’ and 1’ thick or can be as large
as 10’x10’ and 2’-6” thick. A typical footing is
7’-6”x 7’6” and is 2’ thick. Concrete piers
are also used throughout the basement wall for extra strength. These piers
are typically 1’-8” by 2’-4”. Both spread footings
and piers have reinforcing ranging from #5’s to #9’s. The basement
exterior wall is a typical 12” Ivany block except for the section
under the rotunda entrance, which is reinforced concrete. This wall extends
to the 2nd floor and is then replaced by a curtain wall. Basement floor
construction consists of a 4” concrete slab, reinforced with 6x6 w1.4
x w1.4 wwf on a 6mil vapor barrier placed on a minimum of 4” compacted
stone. The 2nd-4th floors are framed with structural steel. Typical girders
are found to be W24x55 and W14x22. Beams running N-S are much smaller (W12x16
up to W16x26) than the beams running E-W (W16x26 up to W24X76). Non-composite
decking is set on 24k4 joists that are spaced at 2’ apart. On top
of the decking is a 3” concrete topping rated at 3000psi. The roof
decking is relatively the same as the floors below except when placed under
the AHU, the decking then becomes 24k6. The building utilizes a moment frame
as its lateral reinforcing system. All structural steel is 50ksi steel.
Construction:
Before construction can commence the existing 2-story, 7,060 SF brick building
must be demolished. All landscape, sidewalks, pavement, and signs must be
removed also. There was no CM affiliated with the job, all coordination
went through the General contractor. The project is a Design-Bid-Build project
with Lump Sum payment.
Mechanical:
Through the agreement with the owner of the project, specific mechanical
information can not be researched nor can it be posted.
Lighting:
The basement is mostly unused space. Here you can find numerous strips of
1x8 pendent mounted fluorescent lighting with (4) F32/T8 lamps. In the 1st
floor lobby a grand 42” diameter acrylic diffuser with (8) 26W triple,
4-pin fluorescent lamps is used to greet its customers. Throughout the building
in offices, storage, and file rooms a typical 2x4 recessed louver with a
curved acrylic lens are used. The lamps are (2) F32/T8. Lighting in most
of the hallways, in waiting areas, and in the bathrooms consists of fluorescent
down lighting which is recessed. The lamps used are (1) 175W metal halide
mogul base lamp. In some of the main conference rooms, a recessed low voltage
downlight with a clear reflector is used. The lamp is (1) 50W MR16. On the
exterior side of the NE entrance, decorative Bollard lighting is used to
accent the entrance. The lamps are GM2070MHI, Dark Blue composite with 70W,
double ended with asymmetric reflectors. Optics to light 6ft high corporate
signs is provided flush mounted in the earth or in concrete. Lighting provided
in the drive thru area is (7) 25W A15 medium base fluorescent lighting.
The panel boards for the entire floor are located in one central location, on the west side of the elevator bays in an electrical closet. There are 2 sets of 3 panel boards, one of which is designated as normal/emergency in case of a power outage. Each panel board is designated as 208Y/120V, 3 phase, 4 wire except for one panel board which is 277Y/408V 3 phase, 4 wire. The main line to the building from the transformer is 2500A/3 phase, 4 wire and ground, (8) 4” conduits each with 4- 500kcmil and 1- 350kcmil ground. The junction box for the connection to the site lighting features is 208V, 1 phase. Many of the conference rooms and bathrooms are equipped with an ultrasonic occupancy sensor with adjustable time delay and sensitivity settings. This sensor is set at 24V. 12 AWG is used for all homeruns. Door security alarm systems are 120V. Located on the top of the N/E entrance over hang is a snow melt/ deicing system.
Fire Protection:
Sprinkler systems are provided on all floors. The basement has exposed sprinkler
heads where the other floors are all concealed. The peak fire protection
demand is up to 750gpm. In the area of alarm systems and monitoring devices,
there are smoke detectors for computer/file rooms. A monitor module is in
place to monitor the entire building and when a fire is detected a building
wide alarm will sound. A fire alarm control panel is also provided for pre-action
fire protection functions.
Telecommunications:
The offices are provided with 4 voice outlets and 2 data outlets. Cables
are run above the ceiling and must provide 100ft of extra cable for future
extension. Several offices are fitted with CAT5E cable for connection to
Bumberg Informational Systems.
Transportation:
There are 2 elevators located in the center core of the building plan. The
elevators have 5 stops (one for each floor). The elevator has a total rise
of 54.8’. Elevator 1 is rated at 2500lbs; elevator 2 is rated at 3000lbs.
The rated speed is 125 ft/min. Elevator car 1 dimensions are 6’-8”
wide by 4’-3” deep. Elevator car 2 is 6’-8” wide
by 6’-3” deep. The entrance to the elevators is 3’-6”
wide. The main power supply to the elevator is 480V +/- 5% of normal 3 phase.
Lighting supply is 120V, 1 phase, 15A, 60 Hz.
Special Systems:
Since there is a bank on the first floor of the building, an electronic
security system for the building will be installed. Motion sensors, video
surveillance, and electric strike locks are provided as security measures.
A drive thru banking system is provided on the site. There are 3 stations
to pull up to. Typical VAT “23” customer units with 1 way CCTV
are used to process transactions. (Large compressed air tubes used to transport
physical transactions to the bank teller.)
