Question 5:

Are there any restriction on size and weight of the operating equipment in the tunnel?

ventilation, man-basket, raising and lowering transport vehicles and materials, etc.

Question 10:

Please provide description of requirements for site security during construction as well as off-shift requirements.

Response 10:

Response 15:

There will be water seeping into the excavated areas, it’s unknown how much. Continuous water removal from excavated areas will be crucial, as noted in Specification 31 03 33- Water removal.

Response 18:

The contractor is responsible for off-shift site security and is responsible for both locations. See

Section 01 14 10, Use of Site. Patrolling is permitted after coordination is made with the

National Park Service for the Crystal Creek By-pass location and the Trinity Fish Hatchery

Supervisor is notified for the Lewiston Portal.

Question 19:

Please provide clarification on the Initial Amount vs Initial Contract Amount on the PPQ form

(pg. 105 of the solicitation).

Response 19:

These two blocks should represent the same value.

Question 20:
