Questions and Answers 140P5324Q0011

1. Question: Portions of the road are stated as being 9' wide. This is not wide enough for trucks to turn around. How long are these segments and are there turn around areas close to these narrow sections (on one end of the narrow section).

Answer: We have designated areas for turning at both ends of the segments requiring tailgate spreading. It is crucial to emphasize that the preservation of our natural and historical landscape is a priority over modifications for contractor convenience. We expect our contractors to demonstrate adaptability and resourcefulness in navigating these project constraints. BISO is not interested or willing to widen our trails as such.

2. Question: When the road is only 9' wide, tailgate spreading of the material is likely to involve material spilling off the sides of the road. There is no way to eliminate this from taking place. Also, narrow road widths may present safety issues for any tailgate spreading if they are combined with elevation changes or sharp curves.

Answer: The potential for material overflow during tailgate spreading, regardless of road width, is a known factor in such projects. We anticipate that contractors will employ effective management strategies to minimize environmental impacts, maintaining our standard practice for road maintenance within the NRRA.

3. Question: Areas of the road that have only got 11' high clearance will present a barrier for any standard trucks to pass under. The minimum height for safe truck clearance is around 13'6" or

14" (we understand 14 '' is the state normal standard). Only specialized equipment, not normal delivery trucks, will need to be utilized to pass under this area and deliver material to the remainder of the road. Additional information on the location of these low clearance areas as they relate to the total area of the road to be rehabilitated will need to be provided and we would anticipate a significant increase in costs.

Answer: The specification regarding the 11' high clearance has been met in previous projects using what is commonly recognized as "standard" delivery trucks. We wish to reiterate that there will be no adjustments made to the infrastructure to accommodate larger vehicles. Innovation within the given parameters is encouraged rather than expecting infrastructural modifications.

4. Question: The period of performance is shown as four months with truck rental for two months.

We are not sure what traffic control measures would apply when the road is as narrow as reported. For a two month period, would the road need to be closed or trucks supplied by the contractor to help lead the public through areas of construction? We have seen this situation handled in other National Parks and it can be very costly and involved. When that cost in providing the requested traffic control is evaluated along with the two-month period of delivery, the total cost to satisfy this request might be more than all of the other costs for this solicitation combined.

Answer: The responsibility for traffic control will rest with the contractor. This approach is in line with our commitment to cost-effectiveness and equitable bidding processes. Contractors should factor in the complexity of navigating construction areas in their bids, leveraging their expertise to ensure safety and efficiency for park visitors.
