Stillwater Hunter Road Gravel Project

This amendment is hereby issued to respond to a

RFI Q&A:

Q1: After reviewing this requirement with our subcontractor, we received the following clarification from them:

"If the trucks ran consecutively, they could all dump in sequence, allowing the refuge staff time to work the material before the trucks returned for their second and third trips. The total daily tonnage can be adjusted to suit your needs by increasing or decreasing the number of trucks. We anticipate approximately

800 - 1,000 tons per shift. The material would be delivered using belly dump trains, leaving a window for the refuge staff to spread.

We would revise the proposal to include minimum truck spacing. However, doing so would limit roughly half the trucks to only two loads per day, increasing the cost per ton. Based on this scenario and eight trucks per day, spacing would be approximately 15-30 minutes between loads, followed by about 1.25 hours of downtime between the last truck in the first rotation and the first truck returning for the second rotation. This would result in approximately

800 tons per shift."

Based on this, strict adherence to the minimum

15-minute spacing requirement would materially affect operational efficiency and increase the cost per ton.

We would respectfully like to inquire whether there is any flexibility in the delivery spacing requirement. Specifically:

A. Would consecutive dumping be acceptable if coordinated safely and efficiently with the grading contractor?

B. Is the 15-minute minimum interval mandatory throughout the entire shift, or could it be adjusted during certain delivery windows?

C. Would alternative staging or sequencing methods be considered, provided safety and site control are maintained?

A1: The refuge does have some flexibility on

During the work day - we will have a refuge staff member who is stationed to take the tickets from drivers and direct them when it is safe to unload. However, we have completed similar projects at least three times in the past 5 years with various contractors.

A 15-minute interval between trucks was generally what they averaged between trucks just based on how long it took the for each load to be filled between the first and the next truck at the gravel pit. Across the projects, delivery has averaged between 800-1k tons per day.

For the specific questions:

A. Yes, consecutive dumping can be coordinated with the refuge staff who will be completing the gravel grading.

B. The 15 minute interval would not be mandatory and could vary throughout the shift, but would need to be coordinated with staff on site.

C. Alternative staging or sequencing methods could be considered, provided safety and site control are maintained. The contractor would be responsible for coordinating with the project manager on site and ultimately would be responsible for ensuring the gravel is delivered to its final location on the delivery route.
