The Acacia Gardens development in Dubai included two distinctive highrise residential  towers. SGI provided comprehensive Structural Design and Engineering Services for the  project. The 39-story Olgana Tower had a Gross Floor Area of approximately 680,000  square feet. The Podium and Basement levels of the building are dedicated to parking  facilities serving the residential floors above. Primarily, a cast-in-place reinforced concrete  structural system was used throughout the building. Reinforced concrete shear walls are used  at the core of the building and at several other locations outside the core. These shear walls,  in combination with frame interaction, serve as the lateral system to resist wind and seismic  forces.
