3.1.4.a - Telecommunications Duct Banks: Concrete encasement: In new construction (BRAC/MCA), the duct system shall be concrete encased in all main cantonment areas of JBLM shall be constructed of Rigid Nonmetallic Conduit Schedule 40 – for direct burial or encasement in concrete (shall meet NEMA Standard TC-2) in concrete of minimum 3,000 lbs./in2 (20,700 kPa) compressive strength where vehicular traffic (i.e., automotive, railway) is above the pathway or where a bend or sweep is placed.  unless otherwise specified by specification, standard, or design criteria. In preparing the trench bed for the conduit installation, the trench bed shall be leveled to form an even base. In some cases, it may be necessary to provide sand or fine earth to establish an even base. If, upon excavation, the trench bed appears to be incapable of firmly supporting the conduit, the Engineer shall determine whether a concrete base is required (RUS Bulletin 1753F-151). Duct spacers are required, and duct bank properly formed and framed prior to concrete pour.

DPW as owners of the duct bank and maintenance hole system and NEC as owners of the cabling that utilizes the duct bank and maintenance hole system. All inner ducts shall be I3A compliant fabric mesh inner duct. Each 4” ducts requiring inner duct shall contain fabric mesh tapes consisting of a minimum of (three) 3-inch, 3-cell per tape, maximum of three tapes/nine cells per duct.
3.1.4.c) Technical Criteria for the Installation Information Infrastructure Architecture (OSP), November 2017 (I3A 2017) - 3.7.4.6 Duct Installation Guidelines: a. Depth of cover: At least 24 inches (600 mm) of cover are required above the top of the duct bank. At least 18 inches (457 mm) of cover are required under roads or sidewalks (if duct is concrete-encased). For ducts installed in solid rock, the cover shall consist of at least 150 mm (6 inches) of concrete. If rock is encountered below grade, the minimum cover above the concrete-encased duct shall be 12 inches (300 mm). Refer to Figure C-3 (Figure C-10 for Europe), Conduit Placement/Cut and Resurface, for details. The cover or fill shall be compacted IAW UFGS-02300.
3.1.4.d) Existing conduit systems located within the construction area, if damaged due to construction activities, shall be repaired and encased in concrete by the contractor. Any existing conduit systems located in the construction area that will be, by design, paved over for a parking lot, driveway, and/or entranceway shall be concrete encased by contractor prior to moving vehicles or equipment over the top of the conduit system.
