Best Private Building Project
The Shaw Group Headquarters

Contractor: MAPP Construction, Baton Rouge
Location: Baton Rouge
Cost: $40.5 million
Project manager: Mark Stirling
Jobsite superintendents: Tommy Tucker, Roy Aicklen, Ray Ratcliff
Architect: Gensler, Houston, Texas


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.
