Noddle, who also has developed Aksarben Village and other properties in the city, said Kiewit’s plan calls for a building with 165,000 to 185,000 square feet at a cost he estimated between $49.5 million and $60.2 million.

An adjacent garage would hold 600 to 650 vehicles and cost between $13.2 million and $16.3 million.

“We’re just starting in on the design process,” Noddle said, but the office building will have from five to nine stories. “We’re concerned about developing a highly efficient and high-quality campus and fitting into the neighborhood.”

The company reached a “memorandum of understanding” with Mayor Jean Stothert on Tuesday and hired Noddle Development Co. and HDR.

Noddle said the agreement calls for the City of Omaha to vacate the block of Burt Street that crosses the property and to help with acquiring the land, including the use of eminent domain if necessary. Kiewit has bought or signed purchase agreements for all but one parcel and is working to buy that, he said.

Construction would begin as soon as is practical, he said, and Kiewit could move in as early as 2020, although exact dates are not set.
