Sidewalks should be concrete per detail on C-510.

The proposed 10-way ductbank to be installed runs through several existing sidewalks that are not shown to be demolished. The demolition civil drawing is incomplete as these sidewalks will be missed by the civil contractors.

Contractor will be required to demo and replace any sidewalks within the path of the ductbanks.
