Architecture

Architecture:  The Game Day Building is intended to be an iconic addition to the existing stands in preparation of starting a football program in 2009.  The first floor is comprised of locker room and training facilities, coaching offices, concessions, and restrooms. The 2nd floor has mini-box seating, a kitchen, a scholarship lounge, and additional restrooms and concessions.  The 3rd and 4th floors have 12 luxury suites each and additional rooms such as sound/lighting/scoreboard control.  The roof is nearly flat with cast stone parapets.

Major National Model Codes:  The building is governed by the 2003 (VUSBC) Virginia Uniform Standard Building Code.  This is an amended version of the 2003 IBC.

Zoning:  The site is zoned as (IN-2) an Institutional Campus District by the City of Norfolk, Virginia.  This zoning is intended to accommodate the unique multi-function needs of universities and permits most occupancy types.

Historical Requirements of Building:  N/A

Building Envelope:  The majority of the façade is clad in brick masonry with cast stone trim.  Additionally there are portions clad in cast stone masonry, storefront glazing systems with ANOD. Aluminum framing, painted metal railings, and cast in place concrete with a rubbed finish.  The south face of the building is accentuated by five one story and a three story entry archway clad in cast in stone masonry adorned with two aluminum flag polls.  The north façade is distinguished by the cantilevered balconies with seating, large areas of glass curtain wall, and a scoreboard.  A 12” concrete slab topped with single-ply membrane over coverboard over roof insulation provides the roofing system.

Building Statistics Part 2

Structural

The Foreman Field Game Day Building is a 54,877 square foot, 47 ft. tall, four story, concrete structure with a distinctly curved plan.  The primary gravity resisting system is two-way flat plate reinforced concrete.  The average floor is approximately three bays wide and eight bay long with a typical bay being approximately 17’x31’-6” with a slab depth of 12”.  The buildings lateral resistance is provided by seven full height cast in place concrete shear walls.  Normal weight 5000psi concrete was used in structural concrete elements of the building.

The deep foundation determined to be the most appropriate is 12” square precast prestressed concrete (SPPC) piles.  Approximately 200 piles, 100’ long from tip to cutoff, are located in groups of up to 18 below columns, perimeter grade beams, and shear walls.  The shallow foundations are comprised of 36” to 40” deep pile caps, grade beams between pile caps and continuous wall footings. 

The ground floor is a slab on grade typically 4” deep, reinforced with WWF, and above 6” of compacted porous fill.  The 2nd floor, in addition to concrete flat plate slabs, has five rows of stepped down seating on north facing the football field.  The seating is supported by 14”x19” concrete beams spanning 18’ parallel to the rows that frame into 18”x15-24” sloped girders along column lines.  The 3rd floor 4th floor and roof are almost entirely 12” flat plate with the exterior bays becoming progressively narrower on higher floors.  An exception on the 3rd floor is the metal kitchen roof on the south face of the building supported by cold formed metal stud joists.

The seven cast in place shear walls that provide the buildings lateral support are located surrounding stairwells on the east and west sides of the building and one in each direction near the center of the building. by 12” shear walls.  Typical shear reinforcement is two curtains of #5 rebar 12” on center both horizontally and vertically.  Flexural reinforcement varies greatly both between walls and relative to height from 2#6 bars to 7#9 bars.

Mechanical

On the first floor the locker rooms and training facilities are served directly by one of two 100% outdoor air handling units located on the Game Day Building’s roof.  Supplemental heating is provided to these spaces by electric unit heaters located throughout the rooms.

The upscale scholarship lounge on the second floor is supplied by a gas fired single-package roof top unit which utilizes the only return air system in the building.  The kitchen’s mechanical system consists of a “Make-Up” air unit with gas fired heating capabilities and several exhaust hoods.

The second 100% outdoor air handling unit supplies a series of variable refrigerant heat pumps that provide additional heating and cooling of the air supplied to diffusers in the 3rd and 4th floor suites, control, recruiting, and group sale rooms.

The remaining spaces in the building such as restrooms, concessions, utility rooms etc.., are heated and cooled by zone DX split system heat pumps or electric unit heaters.  Ventilation in these areas is only directly dealt with by exhaust ducts in restrooms and the pantries.  The hallways throughout the building are not conditioned spaces.

Electrical 

Power is supplied at 480V to the building through one of two separately metered distribution panels in a main switch board in the accompanying parking garage.   This panel feeds high voltage panels and 112.5KVA to 150KVA, 480V 3 phase 3 wire- 208Y/120 3 phase 4 wire, step down transformers.  The Lighting and some of the HVAC equipment is run at 480Y/277V off the high voltage panels.  The remainder of the equipment and receptacles run on 208Y/120V on low voltage panels fed by the step down transformers.  A 175kw, 480Y/277 diesel engine generator provides backup power for emergency lighting, medical equipment, elevator equipment, walk-in coolers and freezers, and some minimal HVAC systems.

Lighting

The overall building lighting scheme is fairly simple.  Locker rooms, offices, restrooms, concessions, and other service areas are lit with a combination of recessed and ceiling mounted direct florescent troffers.  Public egress spaces are lit with compact florescent cans.  The Scholarship Lounge intended for yearlong use for receptions and other publicity functions utilizes direct/indirect luminaires for a more upscale appearance.

The Lighting system runs on 277V.  Exterior lights are automatically controlled by both a timer and a light sensor on the roof.  Some Interior lights are attached to a day lighting system controlled by exterior mounted photocell light detectors on the north face of the building.

Fire Protection

A dry type automatic sprinkler system and horn/strobe units are provided on all floors.  The Primary fire construction type is IIB with approved automatic sprinkler system throughout per IBS 903.3.1.1.  The subsequent minimum fire resistance ratings according to IBC Table 601 are as follows.

This results in the only substantial use of fire rated walls being two hour walls around stairwells and utility shafts.  Additionally 30 minute rated separations are provided between individual suites on the 3rd and 4th floors.  The roof covering fire classification is Class “C” per IBC Table 1505.1.  Accessible egress is considered provided by elevated walkways connecting to the accompanying parking garage which has an elevator and the two main stairwells (IBS 1007.2.1.1, 1007.3.2, & 1007.3.3).

Construction

The construction of the Foreman Field Game day building is being carried out from February 2008 thru July 2009 for an estimated cost of $11.9 million. The project delivery method is a design-build contract.  Project completion deadline is very important as the The Old Dominion Monarchs are scheduled to host the Chowan University Hawks at Foreman Field on Sept. 5, 2009.  Being ODU’s first football game in nearly 70 years it will be highly anticipated and publicized.  The General Contractor on the project is S.B. Ballard Construction Company who’s been named the General Contractor on several other recent projects for ODU.  Some special construction issues Foreman Field presents are lead paint and asbestos abatement on the existing 1934 structure and reducing the two foot crown in mid field too approximately 4 inches.

Transportation

The Game Day Building has three stairwells.  Stair 1 and 2 on the east and west sides of the building provide the access from the ground to 4th floors.  Stair 3 located in the far south-east corner of the building provides direct access from street level to the Scholarship Lounge on the 2nd floor.  An elevator in the accompanying parking garage can be accessed via elevated walkways on 2nd through 4th floors.

Geotechnical 

The entire site’s subsurface soils are comprised of a combination of wet sands and clays with low load bearing capacities. Therefore, a deep foundation system is required to achieve the required bearing strengths.  The water table was found to be approximately six feet below current grade.  The following table summarizes the boring test results across the site.
