With 100-megabit service one can watch five movies, search the Web and answer emails at the same time.

Allo will connect downtown Lincoln first, then begin work on the east Lincoln area, Moline said.

Construction crews will work in smaller areas of about 1,000 homes and businesses at a time. And as it adds fiber, the company will be behind every home and business and in city rights-of-way, said Moline.

"Bear with us. We will leave the property as we found it. But it is a huge undertaking," he said.

The company recently ordered 5 million feet of conduit, 30 vans and 10 trucks, and splice trailers.

Allo might not get to the entire eastern section in 2016, Moline said, but "we will make every effort to do so."

And if the eastern section is finished this year, then it may not take the entire four years to provide the 1-gigabit option to the entire city, he said.

Allo is working with Lincoln-based Olsson Associates engineering and design firm to finalize the construction schedule.
