FAIRVIEW BOAT RAMP OVERLAY

PREBID MEETING Q & A

Q: What will the lake level be at time of award and what happens if lake level does not allow construction?

A: At present, the lake is 34’ below the bottom of the ramp. Bottom of ramp is at 2,309’ elevation. The Bureau of Reclamation has predicted that the lake elevation will likely not reach the bottom of the ramp this year. However if this occurs, negotiation with the Contracting Officer will be required.

Q: Is camping on site permitted?

A: Yes, with camp permit.

Q: What is the compressive strength required of concrete?

A: From plans, “Concrete shall be a minimum 6 sack mix with a minimum 28-day compressive strength of 4,000 psi, maximum slump of 3-4 inches and 5% (+/-1%) entrained air.”

Q: Where is the dump place for removed concrete from curb and transition ramp and slough material?

A: IMPORTANT: At the meeting, we stated that it would be approved to remove the slough material to beyond the bottom of the ramp. However, after reviewing our permit for construction, all material will be removed to disposal area located on Pettijohn Mountain that is 2.5 miles away.

Q: What is the overlap for rebar splices?

A: Specifications call for abiding by Building Code Requirements for Reinforced Concrete, American Concrete Institute. Our Engineer calculated a 20-inch overlap.

Q: Will curing retardant be allowed in the concrete?

A: Specification 552 states that “Set retarding and/or water reducing admixtures may be used provided they conform to the requirements of Type B or Type D of AASHTO M-194 or ASTM C 494. The type and quantity of the admixture to be used must be included in the mix design submitted to the Engineer. The use of the admixture shall conform to the manufacturer’s recommendations.
