Omni Hotels and Resorts has filed a building permit to start construction on a 605-room hotel that will adjoin a new convention center already under construction in the area known as Core to Shore.

Construction of the $235.5 million hotel at 400 S Robinson Ave. is set to start in September with an estimated completion in two years.

With construction set to start on the hotel, the only component of the Core to Shore plan still under design is an 850-space garage that will serve the hotel, convention center and Scissortail Park.

That site, currently home to an OGE Energy Corp. data center, is set to be turned over to the city next March. A 241-unit apartment tower with retail is set to be built wrapping around the garage.
