EM Structural Engineers provided structural design and construction administration services for this project for Gateway Development Services. The project is a Class A office building consisting of 200,000 SF, 9-story post-tensioned concrete frame office building supported on drilled pier deep foundations. It features 43 ft x 30 ft bays for optimal leasing.
The structural system is a one-way slab with 21-inch deep beams and girders providing large open spaces required for Class A office spaces. The lateral system is an ordinary reinforced concrete moment frame.
Challenges included a long cantilever on the south face of the building to provide unobstructed views of the city, and a long transfer beam to allow offset columns on the ground.
