<br />intermediate Metal Conduit (IMC). Flexible conduit shall not be used in lieu of EMT, IMC or rigid conduit
<br />except as noted herein.
<br />Galvanized rigid conduit (GRC) or intermediate metal conduit (IMC) shall be used as follows:
<br />When considered exposed to damage by the local AHJ.
<br />When installed in concrete and masonry. The use of ENT in CMU walls and parking structures may be
<br />allowed only as directed in writing by the Engineer. Request for ENT substitution must be made prior to
<br />bid and in accordance with pre-bid substitution request requirements of these specifications.
<br />When noted on the drawings.
<br />When installed in wet or damp locations and of a trade size where listed-raintight fittings, connectors,
<br />couplings, etc. are unavailable.
<br />When required by NEC or CEC Article 517.13

<br />c.
<br />d.
<br />e.
<br />5.Flexible liquid-tight conduit shall be installed in lieu of the flexible steel where required by NEC, or CEC where
<br />adopted, in damp and wet location, where exposed to weather, in refrigerated area (65 Deg. F or less), and/or
<br />between seismic joints. All rotating electrical equipment shall be supplied with flexible, liquid-tight conduit with
<br />appropriate slack and shall not exceed thirty-six (36) inches. Include a separate insulated green ground
<br />conductor sized per NEC in each conduit. Other uses of liquid-tight flexible conduit shall be allowed as
<br />approved in writing by the Engineer on a case by case basis.
<br />3.Provide a 1-1/2" high housekeeping pad above finished floor/finished for service equipment. Prior to pad
<br />rough-in, Contractor shall verify serving utility company's maximum meter height requirements and, if
<br />necessary, adjust height of housekeeping pad to comply with those requirements. In indoor applications, the
<br />pad shall be flush with the face of the switchgear. In outdoor applications, the housekeeping pad shall extend
<br />a minimum of 4 feet from the front of switchgear's weatherproof enclosure. Confirm pad dimensions with local
<br />inspector prior to forming pad to ensure any local code interpretations/conditions are met regarding
<br />housekeeping pads.
<br />Provide a minimum 3" high housekeeping pad above finished floor/finished grade for all floor-mounted
<br />switchgear, switchboards, distribution boards, transformers, motor control centers, etc., flush with the face of
<br />the equipment. Located in mechanical central plant(s), other mechanical spaces, and located outdoors, pads
<br />shall be flush with the face of the equipment. Confirm pad dimensions with local inspector prior to forming pad
<br />to ensure any local code interpretations/conditions are met regarding housekeeping pads.
<br />1.
<br />G.House Keeping Pads:
<br />i.Lightning Protection Systems and antennas.
<br />11.Where conduit is underground, under slabs or grade, exposed to the weather, or in wet locations, make joints
<br />liquid tight and gas tight.
<br />Underground conduits, which terminate inside building(s) below grade, such as in a basement level, or
<br />which slope so that water might flow into interior building spaces, shall be sealed at the point of
<br />penetration with a modular conduit seal (Link-Seal or equal by Rox Systems). Conduit/conduit sealing
<br />system penetrations of waterproofing membranes/systems on existing structures shall be completely
<br />restored as required to maintain membrane/system manufacturer and installer warrantee for the
<br />installation. All conduits shall be provided with a 4% slope away from buildings. All conduits shall be
<br />installed such that the water cannot accumulate in the conduit and such that water drains into the nearest
<br />manhole, pull box or vault and not into the facility. In instances where grade changes or elevation
<br />differences prevent sloping of conduit away from a building into the nearest manhole, pull box or vault or
<br />where accumulation of water in a manhole, pull box or vault may result in water traveling into the facility,
<br />conduits shall be sealed internally at each end of each conduit using conduit sealing bushing, sized as
<br />required for the conductors contained within the conduit (O-Z Gedney #CSBG 100psig withstand or
<br />equal). In all cases, install plugs or caps in spare (empty) conduits at both ends of each conduit
<br />(Jackmoon or equal) preventing both water and gas from entering the facility via the conduits.
<br />e.
<br />Where underground conduit passes under a building slab, concrete encasement may not be required,
<br />except as required above, contact the Engineer for written direction prior to omitting any encasement.
<br />d.
<br />c.In all cases, where any conduit(s) pass under a building slab or footing, the electrical contractor will
<br />provide a Bentonite clay or concrete barrier that conforms to the height and width of the trench excavation
<br />extending a minimum of 24" on either side of the foundation. In all cases, where conduit(s) pass through
<br />a sleeve in a footing or other foundation element, the electrical contractor will provide a Bentonite clay or
<br />concrete barrier between the sleeve and the conduit(s) surrounding the conduit(s) for the entire depth of
<br />the sleeve. The barrier is required to prevent passage of moisture under or through the slab or footing via
<br />the trench or sleeve.
<br />b.For all communications conduits 2" and larger, and feeders 100A or greater, provide with a minimum 3",
<br />(2,000 LB) concrete envelope, 2" minimum separation between conduits, installed at depth of not less
<br />than 24" below grade. (Provide concrete encasement and/or greater minimum conduit depth as required
<br />by the Utility Companies.) Conduit separation within a duct bank shall be maintained using plastic
<br />spacers located at 5'-0" intervals. Where power and communication conduits are run in a common trench,
<br />a 12" minimum separation shall be maintained between power and communication conduits or as required
<br />by Utility Companies. Where concrete encasement is not required by serving utlities for a utility-only duct
<br />bank, provide free draining sand bedding suitable to acheive 95% relative compaction based on ASTM
<br />D1557 using 6" lifts or directed by Utility Company Standards.
<br />a.Underground conduit shall be Schedule 40 PVC (polyvinyl chloride) unless otherwise indicated elsewhere
<br />in these specifications or as required per NEC, or CEC where adopted, Article 517.13.

<br />selections with the authority having jurisdiction prior to installation. The Contractor shall install each firestop
<br />assembly/system in accordance with the manufacturer's printed instructions
<br />The Contractor shall be responsible for furnishing all material, labor, equipment, and services in conjunction
<br />with the selection and installation of a complete, fully functioning, code compliant, UL-listed, fire stop
