Conceptual Master Plan - Emeryville Center of Community Life

CONCEPTUAL DESIGN January 9, 2009
Emeryville Center of Community Life
deep x 18 gage and would be spaced at 16” on center. They would be attached at the original
roof framing level and would then balloon frame above the new roof level to create the new
perimeter parapet.
3. Building No. 2: Arts/Performance/Dining
Building No. 3, the Arts/Performance/Dining building is a two story building structure of
approximately 32,000-gsf. The ground floor will consist of two multipurpose rooms, kitchen and
storage rooms. The second floor will consist of pre-function and function spaces along with
outdoor terraces. The building's footprint is approximately 80’ in width by 210’ in length with a
configuration of three bays in width by seven bays in length.
The gravity framing for the roof framing will consist of 1-1/2” 18 gage metal roof deck over open
web steel joists or W27x84 roof purlins spaced at 7’-6” on center which clear span the
performing arts area. The gravity framing system for the 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.
4. Building No. 3: Community Services and 7-12 Neighborhood
Building No. 3, the Community Services and 7-12 Neighborhood building is a three story
building structure of approximately 62,000-gsf. The ground floor will consist of the Community
Service components such as lounges, game and art rooms, a café, resource center and prekindergarten.
The second and third floors will consist of classrooms and lab rooms for the 7-12
Neighborhood components. The building's footprint is approximately 80’ in width by 215’.
The gravity framing system for the second and third floors along with the roof 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.
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.
