Architecture: The Administrative Building is 312,000 S.F. which is part of a bigger campus where the total is 715,000 S.F. The new campus connects to an already existing building which is composed of brick, so the use of an exterior brick truss panel is used to match the existing building. This building is split into offices and specialty amenity spaces. The specialty amenity spaces include a cafeteria, fitness center, training center, health services, building and campus support, mailroom and maintenance/support services. The main entrance is located at the north end. There are three main cores providing toilet rooms, vertical transportation, telecommunications and electrical closets.

Zoning: The site crosses two separate zoning districts which are zoned Interchange Office (IO) and Residential (R-1). The Township Solicitor and Zoning Officer have suggested for the purposes of site coverage calculations; the entire site should be included in the IO totals.

Historical Requirements: There are no historical requirements.

Building Envelope: The exterior walls will be a brick truss panel with a window system consisting of a minimum 1" thick insulated tinted low "E" glazing units in aluminum thermally broken fixed frames with a polyvinylidene fluoride resin (PVDF) finish and masonry cavity wall and insulated metal panels at spandrel and opaque areas for specific portions of the building. The floor framing system consists of a concrete slab on composite metal deck spanning between wide flange beams to wide flange girders to wide flange columns. The typical bay sizes are 20' and 40' spaced 10' on center. The roof system will be a single-ply roofing system and mechanically fastened. Insulation will be a minimum of 2" at drains and 3" everywhere else.

Construction: In September 2001, the entire campus site began to be cleared with erosion/sediment control and building pad preparation.  The foundation began on The Administration Building in October 2001 and was completed in July 2003.  The owner moved in on August 28th, 2003.  The project delivery method is Design-Bid-Build.  Special construction consisted of building automation system; CCTV security system, fire alarm system.

Mechanical: Rooftop AHU’s that supply outdoor air to VAV boxes with electric and hot water re-heat.  Heating load demand is provided by two dual-fuel heating hot water boilers and they are each sized for 50% of heating load that are located in a central location that also supply two other buildings.  Central utilities plant with chillers and boilers that provide chilled and hot water.  The use of humidification systems to condition the dry winter air is used.

Electrical: 2-15kV HVL, Medium Voltage Metal-Enclosed Load-Interrupter Switchgear rated at 15 kV, 600 A, 63 kA (SYM, with integral fuses), Anti-single phasing protection distributed by 480/277V and 208/120V system.  Lineup of 5kV Medium Voltage Load Interrupter switches and 2-500KVA substations.  500kW, 480V, 3PH, 3W engine driven generator.

Lighting: Office and support areas will be lighted with T5/T8 linear fluorescent lamps or “biax” long compact fluorescent lamps.  Circulation and toilet rooms will be lighted with T8 linear fluorescent and compact fluorescent lamps.  All linear fluorescent lamps will be TCLP test compliant reduced-mercury type.  Metal halide sources will be used for areas over 25’ in height.  Exterior area lighting will use efficient high-pressure sodium sources to match the existing site.

Structural: The foundation system will consist of reinforced concrete spread footings that are sized utilizing bearing capacities ranging from 4,000 psf at soil bearing footings and 15,000 psf at rock-bearing footings.  The structural floor system is 3¼” concrete slab on a 3”, 20 gauge composite metal deck with ¾” steel studs, supported by wide-flange beams and wide-flange columns.  The typical sizes of the beams range from W18x40 to W30x116.  The girders range from W21x50 to W27x146.  The columns range from W10x43 to W14x211.  The concrete is normal weight (147 pcf), cast-in-place concrete and will have a 28 day strength of 4,000 psi.  The structural roof system consists of a 1½”, 20 gauge, Type B, galvanized metal roof deck with spray fireproofing.  Below mechanical equipment a concrete slab on composite metal deck is used instead of the standard roof deck and the concrete slab is reinforced with 6x6-W2.9xW2.9 W.W.F. to minimize shrinkage cracking.  The framing members supporting the metal deck are either open-web joists or wide flange steel beams at 4’-0” and 5’-0” centers.  The beams supporting the composite slab are wide flange steel beams at 10’-0” centers that span the width of the building.  The typical composite steel-framed building utilizes a braced frame lateral load resisting system.  These frames consist of wide flange columns, wide flange beams at each story and one HSS (hollow structural section) diagonal braces between each story.

Fire Protection: The Administration Building has a required 2 hour fire rating throughout the entire structure. The facility draws water from the Philadelphia Suburban Water Co. (PSWC) 12” public water main with a flow of 2430 gpm which is adequate for the sprinkler system including a 15% safety factor.  Hydrants with be dry barrel type with a pumper connection and 2-2½” connections.  The standpipes are Class I to be provided in all required stairways with a designed flow of 500 gpm.  Automatic sprinklers are to be provided throughout all areas and each floor can be served by a single sprinkler zone.  Special hazard areas are to be provided with fire extinguishers.

Telecommunications: There will be a minimum of 1 Telecommunications Room (TC) on each level.  Spaces will be arranged to permit all workstation outlets to be fed while maintaining a maximum horizontal cable length of 295’. 2 KVA Un-interrupted Power Source (UPS) with a 15 minute battery backup will be provided in the TC rooms.

Transportation: There are 6 passenger elevators and 2 freight elevators. There is a four-story glazed atrium as the main entrance that has stairs to take you to every floor.
