Serta Simmons Headquarters

This project for Holder Properties is the first phase of a full redevelopment of the previously closed GM assembly plant in Doraville, Georgia. The main building is a five-story cast-in-place concrete office building. The structural system is a one-way slab with 21-inch-deep beams and joists providing large open spaces as required by the client. The lateral system for this tower is ordinary moment frames, and the concrete columns are supported on shallow spread footings bearing on soils improved with rammed aggregate pier soil reinforcing.

A separate prefabricated steel building is supported on shallow foundations designed by EM Structural Engineers which provides a client showroom. EM Structural also designed the foundations for a precast parking deck which services the two buildings. Lastly, a large, cantilevered steel canopy between the parking deck and office tower designed by EM Structural allows employees to travel between the two buildings sheltered from weather.
