Proposals are expected Friday from contractors anxious to win the main contract work on the $400 million Jordanelle Dam, now under construction six miles north of Heber.

The earthen dam is described as the kingpin of the Central Utah Project's Bonneville Unit and would create an 320,000 acre-foot reservoir overlaying more than 3,000 acres in the Hailstone Junction area.Preliminary site excavation work has been ongoing for more than one year under a $13 million excavation contract, which was finished last November by Torno America Inc., of San Francisco.

Instead of accepting sealed bids for the dam building contract, the Bureau of Reclamation is negotiating bids with a number of contractors interested in doing the work.

Reclamation spokesman Barry Wirth said the bureau is not saying how many contractors are competing for the project. "I'm not able to speculate on where the price range is or how many proposals we're receiving or how many proposals we're narrowing it down to," Wirth said, "But I can tell you we've had an excellent response to the solicitations."

An engineer's cost estimate for the dam contract is being developed concurrent with the bid negotiating process, Wirth said.

Once awarded, the dam is expected to take three to four years to complete.
