Haywood 273 Percussive Activities
Some hoe-ram hammering of bedrock is anticipated to complete phase 2 of the culvert. There
is shallow bedrock apparent in the vicinity of the phase 2 portion of the culvert. It is anticipated
that this percussive activity will occur intermittently on 2-3 work days over a couple of weeks.
But, this is difficult to estimate with any certainty due to variations in rock density and depth of
bedrock. Pile driving is not expected.
