The Sand Bar project's major features include a reinforced concrete intake structure; 3. 5 miles of twelve foot diameter hard rock tunnel; a reinforced concrete powerhouse enclosing a single, vertical Francis turbine-generator rated at 16. 2 MW; and 2. 5 miles of 115 kV, woodpole transmission line. In addition, providing access to the powerhouse and intake sites required upgrading nine miles of road, rehabilitating two bridges, and installing a permanent floating bridge in the river. The Sand Bar project contract was bid under highly competitive conditions and let for a price forty percent below the engineer's estimate. Now, one year into construction, work progress is indicating commercial operation in the spring of 1986, approximately nine months ahead of the contract schedule.
