Construction

959.05 Surface Preparation. Thoroughly clean and abrade bedrock surfaces. Where necessary to obtain consistent bearing for flat bar against the stone, mill the stone for a good fit. Only remove stone material at points of contact with the flat bar, do not mar the stone surface at other locations.

959.06 Anchors. Install per manufacturer’s installation recommendations. Provide installation recommendations for approval recommendations prior to installation. Use manufacturer supplied setting tool.

959.07 Flat Bar Posts. Install flat bar posts at locations shown on the drawing and as needed to follow the contour of the boulder as approved. Provide a templet onsite showing the proposed fit of the flat bar to the stone and the post prior and obtain approval prior to fabrication.

Individually bend flat bar posts to closely follow the contour of the stone and provide a plumb post installation.

Install stone anchors no more than 15” and no less than 9” apart at points of firm contact between the flat bar and the stone.

Place anchors so studs do not extend more than 3/8” beyond the nut on the finished installation.

Finish tops of strap to a 1/8” radius on corners and round over edges for smooth feel.

Install braces in four locations at front and rear corners of the boulder as approved. Weld braces to flat bar posts.

959.08 Eye nut. Place anchor for eye nut installation at location described at STA 20+49. Install anchor at proper depth in rock so eye nut is tight against rock when fully threaded onto stud. Install “permanent” grade Loc-Tite on threads.

GENERAL NOTES

1). The beginning of work areas are marked on the ground by wood stakes with the work area number written upon them. Leave all stakes in place until such time that the work is accepted by the Government.

If a stake location interferes with construction activities, relocate the stake in a visible location 90 degrees to the trail centerline and outside the construction limits.

Should a stake be missing, notify the Government for replacement prior to the commencement of work in that area.

2). The work areas value shown is approximate feet from the beginning of the project or as referenced.

3). The Minimum Aggregate Surfacing Depth shown is the depth after placement and light compaction.

4). The quantities of steps/stones shown for Types SRS are estimates given for the contractor's convenience only. The actual quantities may vary and the contractor is responsible for verifying the actual quantities.
