Blending Solutions — By combining post-tensioning with voided concrete slabs the designers at Silman Engineers were able to minimize the structural depth, reduce the concrete volume and dead load. In addition, engineers were able to design the post-tensioning more efficiently.

PROJECT VOIDED SLAB ACHIEVEMENTS:

• Enabled a flexible column layout

• Load reduction: 37 psf in voided areas

• Created large open spans with flat soffits

• Combined voided slab and post-tensioned solutions
