3.3
Placement of the FMS
Use the following procedures to place the FMS into the excavation.
1. Fill the bottom of the hole with stone aggregate, tamping it as it is filled to build a 12 inch
(30.5 cm) layer with a level surface. The stone aggregate will provide a stable base to
support the FMS.
2. Use appropriate lifting equipment to place the FMS into the center of the hole. Lifting
loops are provided on either side of the FMS for attaching a sling or chain.
Danger:
Use adequate lifting equipment when installing the FMS. Do not stand in the hole while
placing the FMS in position. An unexpected shift of the FMS could result in personal injury.
Note:
Use crushed rock 3/8-inch or less in size mixed with stone dust (per local practice)
to fill the hole. The name of the material may differ in different geographical areas.
Possible names are Class 5, stone dust, aughts (0s) and ones (1s), or stone aggregate
