The Shaw Group corporate headquarters project was a negotiated,
fast track, team approach project, where MAPP Construction
and design team, Gensler, were hired simultaneously by the
owner, Wampold Companies. The building houses the headquarters
for the international company, the Shaw Group, as well as
the developer's offices on the fourth floor.
The building is a 12-story, cast-in-place concrete structure
supported by 495 14-ft. to 90-ft. precast piles. The pile
caps and grade beams are normal weight concrete. Concrete
columns up to the sixth floor are 5,000 psi. The concrete
columns from the sixth floor to the roof are 4,000 psi. The
elevated slabs consist of beams and joists that are reinforced
with reinforcing steel and post-tensioned cables. These slabs
were poured to achieve a 4,000-psi level.
The exterior of the building consists of handset granite
from levels one through four, with architectural precast from
levels four through 12. Some of the precast has granite banding.
A curtainwall system makes up the balance of the exterior
building, with a GFRC screen wall at the roof and a GFRC cornice
on the annex.
The interior core of the building consists of four traction
elevators and two stairwells. The first and second floors
have a two-story connector building that houses a cafeteria
and workout areas. The annex is constructed of structural
steel, and has an atrium and ornamental railing that overlooks
the first floor lobby.
Floors three through 10 are typical office floors with de-mountable
partitions making up about 50 percent of the walls and dry
wall partitions, making up the remainder of the walls. The
11th and 12th floors house the executive offices.
Also included in the project was a five-level structural
precast parking garage that is connected to the east side
of the main building. The foundations for the garage consist
of 455 precast piles with approximately 55 pile caps and spread
footings.
The parking structure itself is made of precast columns,
beams, girders and double tees with a poured-in-place topping
slab. The garage accommodates 801 parking spaces and the mechanical
electrical plumbing central plant, which is located at the
east end of the garage. The central plant houses the cooling
tower, chillers, pumps, radiator and emergency generator.
