D.†† Maintain the surface of the path in a firm, stable, and slip resistant condition.

 

E.†† Relocate or replace path as required by construction staging.

 

F.†† Place additional granular material as directed by the Engineer.

 

3.02††††† TEMPORARY GRANULAR SIDEWALK

 

A.†† Construct temporary granular sidewalk at locations specified in the contract documents.

 

B.†† Excavate existing ground surface to a nominal depth of 4 inches.† Install 2 by 4 edging along both sides of the excavation.

 

C.†† Place granular surfacing between edging and compact.

 

D.†† Maintain the surface of the granular sidewalk in a firm, stable, and slip resistant condition.

 

E.†† Place additional granular material as directed by the Engineer.

 

3.03††††† TEMPORARY LONGITUDINAL CHANNELIZING DEVICE
