Project Scope A. Description: This project involves road maintenance on the Woodtick Trail within the Walker

Ranger District of the Chippewa National Forest. The road sustained damage from heavy rains in the spring of 2024. The goal of this project is to restore road conditions by addressing surface deficiencies and improving drainage. Work will extend the roadway’s lifespan by replenishing gravel and reclaiming suitable material from the shoulders. Additionally, drainage will be enhanced by removing sediment and debris from ditches to ensure proper water flow away from the road.

B. Scope of Work: This project is comprised of all required labor, equipment, and materials necessary to perform the following work:

1. Work may include but is not limited to: Mobilization, dewatering the work area, culvert replacement(s), removing ruts/potholes/chuckholes or any other roadbed deformities, roadbed compaction, creating proper roadbed drainage by re-grading, shoulder maintenance, ditch cleaning and ditching, material hauling and placement of MnDOT Class 1 gravel. Resurfacing includes providing, hauling, spreading, grading, and compacting MnDOT Class 1 aggregate across the full length and width of the roadway.

The contractor may elect to supply commercially sourced aggregate or, at their option, crush/produce aggregate within the Forest Service owned Big Rice Gravel Pit, provided all material meets MnDOT Class 1 specifications.

2. The intent of the contract is to provide for the complete construction of the project described herein. Unless otherwise provided, the contractor is to furnish all labor, materials, equipment, tools, transportation and supplies and perform all work required to complete the project in reasonably close conformity with the specifications, and in accordance with the provisions of the contract. Payment for contract work will be made only for and under those pay items included in the Schedule of Items. All other work and materials will be considered incidental to and included in the payment for items shown.

B. Spot gravel will be placed to build up the roadbed in areas where the existing surface is unsuitable. Some locations will require up to 1 foot of gravel depth to properly raise and stabilize the roadbed prior to resurfacing.

C. No spot gravelling shall be done until Roadbed Maintenance work is complete in the area to be graveled.

D. Compaction of surfacing shall be achieved by one of the following methods:
