Solicitation 1240LS21R0007 Cabin Hallow Pit Crushing

September 3, 2021

Questions 1: In reading the solicitation, the first two pages show a line item of hauling aggregate from Cabin Hollow and Reeder View pits. The statement of work does not have any hauling in the breakdown or an explanation in the schedule of attachments. Is this a mistake?

Answer 1: This was an error that was previously addressed in Amendment 0003 to the solicitation that was released on 08/26/2021.

Question 2: When we viewed the site at Cabin Hallow, there was mentioned that a geology study was performed. I would like to confirm that the study determined there was incidental rock in the hill face and not solid rock. If there is solid rock we would need to evaluate the use of hammers or drills to provide a correct bid.

Answer 2: The site was recommended and approve by our geologist. There was not a study done to determine it was all incidental rock and not solid rock. We assumed that it was incidental rock, if it is not it would be considered a differing site condition that will be addressed contractually via potential equitable adjustment if that were to happen. Offerors are encouraged to propose with site conditions as they’re currently known.

Question 3: As stated in the bid proposal, the work is looking to be accomplished in the fall of 2021. While I was there I viewed the site when it was dry and then after a rain storm had come through. At this location, if rain does come through abnormally no work will be possible. Will there be meetings with both parties if weather, i.e. rain and snow, becomes a hindrance to the project to determine work schedules?

Answer 3: Weather impacts to the schedule will be discussed in the event they occur.

Question 4: If the project were to be shut down due to weather conditions, would the awardee be able to charge for mobilization back to the site when the weather permitted if cubic yardage of aggregate was not fulfilled?

Answer 4: If weather conditions cause contractors to stop work, that would be considered a differing site condition that will be addressed contractually via potential equitable adjustment if that were to happen. Offerors are encouraged to propose with site conditions as they’re currently known.

Question 5: On the schedule of attachments, it shows an amount of 950 cubic yards of aggregate to be used to price the laying of the road coverage. What is the length of road used to determine that amount of coverage?

Answer 5: The road is approximately 3000 feet in length.

Question 6: Will there be a contingency in case it is required to drill and shoot the material? There could be solid ledge rock under the surface.

Answer 6: If contractors hit a rock ledge, that would be considered a differing site condition that will be addressed contractually via potential equitable adjustment if that were to happen. Offerors are encouraged to propose with site conditions as they’re currently known.

Question 7: What is the outline of the pit? Size?

Answer 7: Please see Attachment 10 - Cabin Hollow Pit Layout.

Question 8: Trees - There will need to be at least a 400’ x 500’ pad built (you obviously have to site the crusher and stockpiles simultaneously); most of this area is covered by aspen trees. What is the tree plan?

Answer 8: There are 2 pads for storage locations. We will not be making too big of pads.

Question 9: We note the 40 hours of pit development time. We estimate that a realistic time is three to four times that.

Answer 9: Peeling topsoil and piling it should not take more than 40 hours. However, Offerors should put their proposed schedule in their proposal. Offerors’ schedules are Factor 2 that will be evaluated in accordance with the RFP.

Question 10: Timing - pit development could be done in May/June. Crushing will have to be June/July and possibly August. This is all depending on the snow pack.

Answer 10: Offerors should put their proposed schedule in their proposal. Offerors’ schedules are Factor 2 that will be evaluated in accordance with the RFP.

Question 11: We are assuming the 6” of material item #3 is creating then placing the road base on the road? The native material on this road may mean that trucks carrying crushing equipment may not be able to even access this site until the 2nd week of June. It is dark/rich/clay filled mountain top soil.

Answer 11: Yes, that is correct, the material will need to be made then placed.
