This instant landmark is a
first class professional office building located in the heart of
downtown Albany, NY.
Parking is available via a 900 car parking garage owned by the City of
Albany Parking Authority and is located behind the building.
The building is also home to one of Albany's most prestigious
restaurants for fine dining,
Angelo’s 677 Prime.

The building’s entrance is
secured by an HID Card Access system and a full time security guard.
Closed circuit TV cameras and recorders monitor both the interior and exterior of
the building 24 hours per day 7 days per week. The building has an
intercom system for off hour notification when the security guard is
not present.
Unique to professional office buildings in Downtown Albany are the
building's 12 balconies as well as its heated sidewalks which surround
the property. The building has redundant fiber networking service and
some added
features of this building include; redundant electric; high efficiency
lighting with occupancy sensors; a Building Management System (BMS) to
monitor all Building and Tenant HVAC equipment; an Uninterrupted Power
Source System and an emergency generator. 677 Broadway is located just
off I 787 (Clinton Avenue Exit) making the building ideal for clients
and employees. It also yields optimum access to surrounding area
businesses and restaurants and is part of the Empire Zone, lending its
benefits to tenants through its Landlord. The building calls to an
earlier era with its use of a glass facade, yet affords all of the
efficiencies and energy savings of the present.
The foundation system includes a 6" thick concrete slab
on grade over a network of reinforced concrete grade-beams and
pile caps. 134 H-piles
(HP14x89) were driven to practical refusal to fully support
the building. Initially six test piles were driven and tested to verify calculated load capacities.
The load capacity of each pile is 120 tons. The grade
beams bind the pile caps together into a rigid matrix so
they act as a single foundation rather than individual
entities. Columns transfer loads directly to the ground
through pile caps and to the piles themselves. The piles were
carefully laid out as to not cause eccentric forces in any one
group of piles.
Gravity loads are resisted by a 4.5" reinforced concrete slab supported by a
regular grid of simply supported beams and girders.
Partial composite beam action and composite deck design are incorporated in to
the structure and bays are typically 25'x25' with some
variations. Sizes of floor members range between W12 and W18
shapes with the appropriate number of shear stud connectors on each
element. A braced frame approach to the structure provided a
relatively simple structural analysis and design as well as
easy constructability. With this design
the connections could be designed as a simple shear tab types.
Load paths for the most part travel straight down columns to the
foundation.
A few members around the perimeter act as transfer girders to
get the gravity loads to the columns. These can be identified on
the plan when the end of a girder frames into
another girder and not a column (usually close to a column
line). Steel decking was noted to span at least 3 bays per
piece, allowing the slab to be designed as such
over supports. Welded wire mesh was used primarily for
shrinkage and temperature concerns. Columns in this structure see no bending
moments and their load capacities are governed by their buckling
limit. Beams and girders are designed as simple beams (pinned
ends) eliminating negative moments making them ideal for composite beam design.
Lateral forces,
wind and seismic, are resisted by 5 braced frames around
the core of the building (2 in the east-west, 3 in the
north-south). Bracing patterns include "K",
inverted "K", and standard diagonal. Each braced frame acts
as a vertical, cantilevered truss. This is the only area in the
structure where combined loading of structural members occurs.
Horizontal members are assumed to be a part of a rigid
diaphragm, and do not carry any loads due to lateral forces.
All story shear forces are carried by the diagonal bracing.
Construction began on September 17, 2003 on a previous parking lot. BBL Construction Services served as the
construction manager and general contractor. The site was large
enough to accommodate the use of a regular mobile crane, thus
eliminating the need for a stationary tower crane. There was a
moderate amount of room directly behind the site for materials
storage and staging. Still, careful planning and scheduling of
deliveries was high priority so that the site wouldn't become
cluttered, difficult, and dangerous. Delivery of materials and
worker transportation was handled with ease as the First Albany
Building is located just off from I-787 right at the end of an
off-ramp in downtown Albany.
With these key conditions, work advanced quickly throughout the
construction phase.
There are two building power
distribution units that have an output capacity of 125 kVA (with 3
integral panel-boards) and 75 kVA (with 2 integral panel-boards)
respectively. Input voltage is 480 volts AC - 3 phase.
Output voltage is 120 / 208 volts AC - 3 phase wye configuration which
is subsequently stepped down at each floor to 110/220 volts AC for
tenant needs.
The building has redundant
fiber networking service and some added features of this building
include; redundant electric; high efficiency lighting with occupancy
sensors; a Building Management System (BMS) to monitor all Building
and Tenant HVAC equipment; an Uninterrupted Power Source System and an
emergency generator. Lighting throughout the building was determined by
expected tenant needs (which varied slightly). A variety of
florescent and recessed lighting fixtures is used to satisfy lighting
requirements.
The primary environmental control system is a
variable air volume (VAV) configuration with reheat coils. The
reheat coils only operate when minimum
ventilation is required. Individual air handling units
serve each floor (multiple zones per floor). An electronic control system
allows the programming of temperature and humidity set-points, alarm
parameters, operational status monitoring, and maintains a database
of zone conditions and operational status.
Control systems are also capable of temperature anticipation,
predictive humidity control, and compressor short cycle control.
Each control system is tied into a complete Building Management System
(BMS) for overall monitoring.
Structural Steel is protected
by spray applied or double-layered drywall fire protection, each rated
at 1 hour minimum. Elevator and stairwells are protected with a 2 hour
rating. The entire building is also protected by a ‘wet pipe’
sprinkler system, meaning the system is always charged and single
sprinkler heads can be activated independently. In moisture sensitive
spaces (communications rooms) Chemical Agent Extinguishing Systems are
present. Individual fire alarm systems (per occupant space or
floor) are tied into a building wide audible fire alarm system for
emergency situations.
Three elevators and two
stairwells serve the building’s occupants continuously from the ground
floor to the mechanical penthouse and roof.
All building pedestrian
traffic must always pass through the main entrance security station,
with no exceptions. The building’s entrance is secured by an HID Card
Access system and a full time security guard. Closed circuit TV
cameras and recorders monitor both the interior and exterior of the
building 24 hours per day 7 days per week. The building has an
intercom system for off hour notification.
All guests and visitors must be announced and/or verified to be
permitted entrance, except for the restaurant patrons and employees
who use a private entrance on the south side of the building.
