Connections to Existing Ducts
Where connections to existing duct lines are indicated, excavate the lines
to the maximum depth required. Cut off lines and remove loose concrete
from the conduits before new concrete encased ducts are installed. Provide
reinforced concrete collar, poured monolithically with the new duct line to
take the shear at the joint of the duct lines.

Reconditioning of Surfaces
3.1.4.1
Unpaved Surface Treatment
Restore unpaved surfaces disturbed during the installation of duct or
direct burial cable to their original elevation and condition. Carefully
preserve existing sod and topsoil and replace after the back-filling is
completed. Replace damaged sod with sod of quality equal to that removed.
Where the surface is disturbed in a newly seeded area, re-seed the restored
surface with the same quantity and formula of seed as that used in the
original seeding.

3.1.5
Cable Pulling
Test duct lines with a mandrel and swab out to remove foreign material
before the pulling of FO media. Avoid damage to cables in setting up
pulling apparatus or in placing tools or hardware. Do not step on media
when entering or leaving the maintenance holes. Do not place media in
ducts other than those shown without prior written approval of the
Contracting Officer. Roll cable reels in the direction indicated by the
arrows painted on the reel flanges. Set up media reels on the same side of
the maintenance hole as the pathway section in which the media is to be
placed. Level the reel and bring into proper alignment with the pathway
section so that the media pays off from the top of the reel in a long
smooth bend into the duct without twisting. Under no circumstances shall
the media be paid off from the bottom of the reel. Check the equipment set
up prior to beginning the media cable pulling to avoid an interruption once
pulling has started. Use a cable feeder guide of suitable dimensions
between media reel and face of duct to protect media and guide cable into
