Donley’s worked with Turner Construction and Smoot Construction on the Columbus Hilton Downtown Expansion. Designed by Cooper Carry, the $220 million project consisted of a 30-story post-tensioned concrete frame tower and a 7-story structural steel frame podium. The project structural engineer was WSP USA. Rising to a height of 357’ above its lowest level, it is the 12th tallest building in Columbus and the largest hotel in Ohio with 1,000 rooms shared between the existing Columbus Hilton Downtown and the new tower.

Donley’s scope of work included basement walls, core and shear walls, columns, slab on grade, tower post-tensioned slabs, and podium slab on metal deck. Unique components of the Columbus Hilton Downtown Expansion project included:

• 10-foot-deep transfer girders on Level 05
• Rooftop restaurant and bar with outdoor terraces providing unobstructed views of the downtown skyline
• Interior connections to the existing Columbus Convention Center and Columbus Hilton Downtown
