Templates

Templates are required when driving piles with swinging leads or with semi-fixed leads. The templates are to be fixed in place and rigid enough to support the pile. Flimsy wood templates are not considered adequate. Do not use floating templates (attached to a barge).

For piles on land, locate the template within 5 feet [1.5 m] of cutoff or within 5 feet [1.5 m] of ground line, whichever is less. For piles in water, locate the template within 5 feet [1.5 m] of cutoff or within 5 feet [1.5 m] of the waterline, whichever is less.

Where practical, place the template so that the pile can be driven to cut-off elevation before removing the template.

This template, constructed of 2"x4" lumber, is obviously not fixed in place or rigid enough to support a pile, therefore it would not be acceptable.

Templates attached to a floating barge are also not acceptable.

Notice how this template is made with H beams and is fixed and very sturdy.
