Bechtel Nevada is currently seeking sources for the drilling of five vertical holes 200' in length into or from tunnel alcoves with an option to drill a sixth hole, 20" diameter x 17' in length, horizontally above a tunnel invert and on the outside of the tunnel portal. The five vertical holes are as follows: #1, 60" diameter into an 18' wide x 13' high tunnel/alcove area; #2, 24" diameter into a 16'6" wide x 13' high tunnel/alcove area; #3, HQ-size, cored continuously, then opened to 6" into a 33' wide x 13' high tunnel/alcove area; #4 and #5, 6" diameter into a 33' wide x 13' high tunnel alcove area. The tunnel drift size is 13' wide x 13' high with at least one 90 degree turn leading to the alcove area. If drilled from the surface, all five vertical holes are to be drilled so that the bottom of each hole is fixed with a tolerance of not greater than 4' deviation from vertical.
