Separate payment will not be made for pumping of water from trenches or for excavation of material rendered unsuitable as a result of water encountered.

F. Unsuitable Material.

Rev 6/19/14 North Umpqua Radio Tower 02318 - 3/5 Excavation & Backfill for Utilities

COR.

G. Backsloping, Sheeting and Shoring.

1. Backsloping of trench walls will be allowed only upon prior written approval of the COR.

2. Remove all shoring and sheeting when construction is completed. Withdraw to prevent trench wall caving while backfilling.

3. When necessary, provide shoring and escape routes per OSHA requirements.

H. Excavated Material.

1. Pile excavated material at the side of the trench where it will give the best protection for the work. Leave adequate space between the toe of the spoil pile and edge of trench to prevent material from falling into the trench.

I. Backfill.

1. Do not place backfill until installation of pipe or cable has been approved by the COR.

2. Before compacting backfill other than rock or sand, prepare material to a water content that will permit proper compaction by either aerating the material if it is too wet, or spraying the material with water if it is too dry. Thoroughly mix each lift before compaction to assure uniform distribution of water content. Do not compact material above pipe or cable until there are 6 inches of cover over the pipe or cable.

3. Compact each lift (with the required number of passes of a mechanical vibrating tamper over the entire layer) (to the required density).

a. Select Material.

b. Select Material.

1) Place in 6 inches lifts or less and compact with a minimum of 3 passes over the entire lift surface.

c. Bedding Material.

1) Place in lifts 4 inches or less in thickness and compact with a minimum of 3 passes over the entire lift surface. Compact around pipe barrel and bells by hand tamping.

d. Select Excavated Material.

1) Distribute large rocks so they are individually surrounded by fine materials. Place select excavated material as follows where backfill classes are indicated on Drawings.

a) Select Excavated Material: Place in 24 inch lifts or less to within

8 inches of finished grade and compact each lift with 3 passes of tamper. On pipe gradients over 30 percent (0.3 foot/foot) place in 12 inch horizontal lifts and compact each lift with 3 passes of tamper.

Rev 6/19/14 North Umpqua Radio Tower 02318 - 4/5 Excavation & Backfill for Utilities

c) Crushed Rock: Place in l2 inch lifts or less, and compact each lift with 6 passes of tamper. At depths greater than 5 feet, compact each lift with 3 passes of tamper.

e. The number of tamper passes required may be reduced upon acceptance by the COR, if approved test method results demonstrate that the backfill compaction meets or exceeds the density of the natural ground adjacent to the trench. Any such testing shall be performed at the Contractor's expense.

4. Water compaction shall not be used.
