GENERAL NOTES

1. Salvage existing aggregate during culvert installation and use as bedding and initial backfill material.

2. Designated disposal site(s) are identified on the plans. The Contracting Officer will flag the disposal areas prior to placement of material. Smooth, shape and compact to drain with spreading equipment as approved by the Contracting Officer.

3. All culvert installations/replacements with flowing water are considered stream channels. Perform work in streams between June 1st through October 15th.

4. All new culvert installations require partial bevel cut (indirect cost to corresponding culvert installation).

5. Minor excavation is required to bevel cut existing culverts and to place riprap for armoring culverts inlets and outlets (indirect cost to items 25101, and 20358B).

6. Anchors, bolts and nuts, wire, and turner elbow construction are an indirect cost to the corresponding outlet pipe installation.

7. Construction tolerance class D.
