2 Is there any chance we could submit the original bid online? No, submit a printed copy of your bid with original bid bonds according to Sheet A-i of the Invitation for bid.
3 The plans says the swell factor is 160%, is that correct? What method is used to measure area and quantity of rock excavation?
Correct, the swell factor for measuring rock excavation is 160% based on a loose placement. Refer to the grading summary on Plan Sheet B3.
Prismoidal surface to surface volume was used for calculations.
4 Is there storage for materials on site? Refer to Special Contract Requirements Subsection 105.04 in the IFB.
Storage areas are to be secured by the contractor.
5 Where are the rock bolts intended to be installed? The rock bolt placement is at direction of the CO, so it will be based on field conditions as exposed during rock excavation during construction.
They are included in the contract to stabilize rocks that are unstable but cannot be removed by traditional slope scaling activities. Refer to Sheet B1 in the plans.
6 If the road closure is after September 2nd, how is the weather during that time?
Weather during this time of season was vetted with the partners. Weather will be getting colder, and some snow may happen. The project is south facing, so if there is any snowfall, it should melt quickly. Refer to FP-14 Subsection 108.03 for weather delay information.
7 Are there predetermined staging areas and source of water that's also 105?
There are no designated water sources. The contractor is responsible for sourcing water. Refer to Section 105.04 of the FP-14 and SCR’s.
8 Please confirm the seeding window. The seeding window is 10/15/24 to 11/15/24. Refer to Subsection 625.11 of the SCR’s.
9 When is the anticipated notice to proceed? Notice to Proceed will be given approximately 2 weeks after award of the contract (award will be in accordance with the Basis for award on Sheet A-4 of the IFB, and NTP is dependant upon contractor returning required acceptable documents in a timely fashion). Contract award is anticipated mid to late May. Ground disturbing activities will commence in accordance with SCR Subsection 108.01.

12 For the river monitoring, I guess I'm not familiar with that river.
How heavy is the river traffic and I presume we'll just have to wait for an open window for blasting opportunities or will there be a way to stop river traffic?
Refer to SCR’s Subsection 156.04 for the Public Information Officer, river monitor, and the duties required. The Public Information Officer will provide a blasting schedule to the county and partner, and they will help notify the public and rafting companies of closures related to the blasting activities. There will also be a river monitor 1500 feet upriver to waive any public river users to the shore.
13 So, there will be some limitation with the commercial companies in regards to rafting at times of blasting?
Yes, there will be.
14 Is there possibility that that the invitation for bid will get extended past April 16th.
