GENERAL CONSTRUCTION NOTES

1. The information contained in the construction log provides stationing and the description of each work item. Completion of work items shall be accomplished according to the drawings and specifications. As built stationing of work items indicated in the trail log may vary somewhat from the originally surveyed stationing. This is due to cumulative changes in distance created during trail construction through drainages, areas of rough topography, and minor changes in trail alignment and gradient.

2. Clearing and grubbing on the Gray Wolf Trail is considered very light and will be considered incidental to excavation. Clearing and Grubbing shall be done in accordance with Section 911 Clearing and Grubbing and no separate payment shall be made. Clearing and Grubbing on the Slab Camp Relocation will be separate from excavation.

3. Existing bedrock benches will be widened from a 2’ wide trail tread to a 4’ wide trail tread with clearance for pack stock. A combination of slough removal, retaining wall construction, and blasting can be used to achieve this. Removal of existing retaining walls shall be considered incidental to the construction of new retaining walls. All existing materials are native an may be scattered on site. Wind rows and piles of materials will not be allowed.

4. This project has been flagged with an “eye level” tag line. A constant grade shall be maintained between flags or stakes. The trail is typically flags and stakes typically follow the desired finished grade, some locations may be centerline staked. The finished grade of the trailbed shall not exceed 15%. Work items are flagged with pink flagging. Flagging is complete at this time. Construction staking is not complete at this time, however, will be completed prior to the start of work.

5. The Contractor will supply and transport all trail construction materials and supplies. Western Red Cedar needed for crib walls and waterbars is located throughout the project area. Logs may need to be transported to specific locations for construction. Stock may be used to transport logs and other construction materials and equipment.

6. The contractor may camp at the Slab Camp Bridge. The camp must be maintained in a neat and clean manor.

7. The contractor is responsible for security of the camp, construction equipment, and materials until final acceptance of work by the Contracting Officer.

8. All drainage dips are considered incidental to excavation.

9. This project is measured in Linear Feet.
