PT high rise wins 1st place at ACI awards

November 8, 2018

Reston Station Office Building 1 (OB1) was awarded 1st place in the high-rise building category at the American Concrete Institute’s (ACI) 2018 Excellence in Concrete Construction awards. CCL supplied the post-tensioning systems for the tower’s two-way, post-tensioned 254 mm-thick concrete slabs in this 16-storey structure.

The building’s design uses exposed concrete to reveal the OB1’s structural system and for architectural purposes. Exposed concrete columns splay outwards to support the post-tensioned slabs which increase in size at each level creating a unique and inspiring shape. CCL is proud to be associated with this iconic structure.
