No rocks or stones larger than 3 inches in diameter shall be allowed in backfill. Material for backfill may be material resulting from excavation, if it meets the above requirements.

Directional drilling will be used for major road crossings. Otherwise, crossing of paved surfaces may be performed by pavement cuts and resurfacing with appropriate matching road material (road cuts must be coordinated and pre-approved by 81 CES 14 days in advance).

Ducts will be appropriately protected when placed under paved surfaces.

New Conduits/Ducts:

Bends and Sweeps:

Accomplish changes in the direction of runs exceeding a total of 10 degrees, either vertically or horizontally, by long sweeping bends having a minimum radius of 20 feet. All bends between MHs shall be a minimum of ten times (10X) the diameter of the duct size (i.e., 4 inch duct = 40 inches) with the sum of bends in all directions not exceeding a total of 90 degrees where practical. Coordination with 81 CS/SCXP is required if runs have bends that total more than 90 degrees.

Long sweeps may be made up of one or more curved or straight sections and/or combinations thereof. Bends made manually shall not reduce the internal diameter of the conduit.

The following definitions apply:

o 90-degree bend: Any radius bends in a piece of pipe that changes the direction of the pipe by 90 degrees.

April 2022 Page 10 of 20 o Kick: A bend in a piece of pipe, usually less than 45 degrees, made to change the direction of the pipe.

o Offset: Two bends usually having the same degree of bend, made to avoid an obstruction blocking the run of the pipe.

o 90-degree sweep: A bend that exceeds the manufacturer’s standard size

90-degree bend (e.g., 24 inches is standard for 4-inch conduit).

o Back-to-back 90-degree bend: Any two 90-degree bends placed closer together than 10 feet in a conduit run. Utilize radius-manufactured bends to the maximum extent possible.

Sweeping 90 Elbow 90

Ducts shall be joined (with glue/cement) in such a manner as to be water tight.

Joints shall form a sufficiently smooth interior surface between joining sections so that cables shall not be damaged when pulled past the joint.

Joints between dissimilar types of ducts (PVC, HDPE, galvanized steel pipe

(GSP), EB, DB, etc.) shall use the appropriate connectors designed for the purpose of providing a seal between the ducts and preventing damage to cables pulled through these joints.

All joint surfaces shall be prepared IAW the manufacturer’s instructions, and, at a minimum, the mating surfaces shall be wiped clean before they are joined.

April 2022 Page 11 of 20

Pull Tape:

All newly installed ducts left vacant shall have a waterproof, corrosion resistant, pre-lubricated flat woven polyester pull tape installed with sequential footage markings, (1250 lb. pulling strength) for future cable installations.

Plugs and Sealers:

All ducts, sub-ducts, HDPE roll pipes and, inner-ducts, whether main or subsidiary runs, shall be plugged using universal duct plugs or removable putty sealants in all MHs, HHs, and building entrances.

Outdoor-rated ducts (sub-ducts, etc.) entering a building will be fire-stopped IAW

The tracer wire shall be exposed; free from the conduit, capped with a wire nut and must NOT be connected to grounds.

The tracer wire shall be secured and routed to the MH/HH neck to a point where maintenance personnel may access the wire without having to enter the MH/HH.

For buildings/communications rooms, attach the tracer wire to backboard above duct entrance.

The tracer wire shall be tagged with a label so indicating it as a “Duct Tracer Wire to xxx – Do Not Remove” (where xxx is the other end of the wire).

April 2022 Page 13 of 20
