GPI provided engineering consulting services to design the mechanical, electrical, plumbing, and fire protection systems for the new Marriott International Headquarters.
The headquarters is located in a newly constructed 785,000 sqft office building. The building is 21 floors, with an additional five levels of below grade parking. The first four levels are “Podium Levels” and were designed as high-end amenity spaces. These four floors house specialty conference center areas and include a soaring monumental staircase that ascends 40 feet, an outdoor plaza, a 9,600 sqft cafeteria, a training area, a commercial kitchen, an executive kitchen and dining area, a child daycare center, a credit union branch, and a fitness/wellness center with locker rooms and showers. Floors five through 20 are designed as high-end office space with over 2,800 open work/collaboration areas, private offices, and 180 conference rooms. The 21st floor is a full floor dedicated to conferencing and training. Employees can also enjoy a 7,600 sqft outdoor garden on the 20th floor.
