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. 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 and CS are estimates given for the contractor's convenience only. Actual quantities may vary; the contractor is responsible for verifying actual quantities.

Where level grade exists between two CS staircases, set CS units as pavers to abut each other end to end. To prevent differential settling, support CS pavers on two 2x7 plank rails ripped from 2x14 recycled PT BW. Joints between 2x7 ends must fall in the middle of a CS paver so adjoining pavers settle as one unit. Embed 2x7 supporting planks in gravel bedding material. Install each CS so as to span both planks and to rest equally on surface of planks and surface of bedding material.
