Conceptual Master Plan - Emeryville Center of Community Life

CONCEPTUAL DESIGN January 9, 2009
Emeryville Center of Community Life
provide 6.5 psf of reinforcing steel. These walls will be founded on 12’x40’x4’ deep footings
with # 9 bars at 6” on center in each direction at the top and bottom of the footing.
In addition, all steel columns within the parking structure will be founded on the exterior and
interior spread footings and will be encased in concrete to the underside of the steel framing.
The concrete will consist of 18”x18” with 4 # 6 bars and #4 column ties at 8” on center.
6. Building No. 5: Community Center
The Community Center Structure is a three story building structure of approximately 46,000-gsf
and will provide offices, library services, art and dance studios and administration services. The
third floor will set back from the building below to create and outdoor terrace which will require
that the roof structure will be designed to support a secondary topping slab and waterproofing
system. The building's footprint is approximately 80’ in width by 181’ in length with a
configuration of three bays in width by six bays in length.
The gravity framing system for the roof and second floor would of 3-1/4" light weight concrete
fill over 3" – 18 gage composite metal floor deck over W18 beams at 10'-0" on center spanning
to W24 girders. The exterior girders around the perimeter would be W24’s at each level.
Typical steel columns which are not part of the lateral system will be W10x49. For estimating
purposes, 8 psf of steel framing may be used to account for roof and floor beams, girders and
columns and perimeter bent plate.
The lateral framing system in the transverse and longitudinal directions will consist of either
eccentric braced frames or buckling restrained braced frames. Four bays of bracing will be
required in each direction and for estimating purposes, 6 psf of steel framing may be used to
account for braces, columns, beams and gusset plate connections.
7. Building No. 6: P.E, Sports/Recreation
The P.E. Sports and Recreation building is a split level, two and three story building structure of
approximately 39,000-gsf. The ground floor will provide lockers, shop, delivery and trash
services. The second floor will support a community gymnasium, storage rooms, fitness and
cardio rooms along with a dance studio. Due to the intended uses a higher level of vibration
control will be required. The roof will create the split level with a two story tall roof height over
the gymnasium and a typical roof height over the workout rooms.
Due to the higher level of vibration control required, the second floor slab will consist of 4-1/2”
light weight concrete fill over 3” – 18 gage composite metal decking over W18 beams at 10'-0"
on center spanning to W24 girders. For estimating purposes, 10 psf of steel framing may be
used to account for the second floor framing including beams, girders, columns and perimeter
bent plate.
The gravity framing system for the low roof would utilize 3-1/4" light weight concrete fill over 3"
– 18 gage composite metal floor deck over W18 beams at 10'-0" on center spanning to W24
girders. The exterior girders around the perimeter would be W24’s at each level. Typical steel
