All bends and offsets shall be made on a forming <br />tool to prevent the conduit or its coating from being damaged in the bending. <br />D Install galvanized steel rigid metal conduit (RMC)in accordance with NECA 101. <br />E Install PVC-coated galvanized steel rigid metal conduit (RMC)using only tools approved by the <br />manufacturer. <br />F Install rigid polyvinyl chloride (PVC)conduit in accordance with NECA 111. <br />G Conduit Routing: <br />1.Unless dimensioned,conduit routing indicated is diagrammatic. <br />2.Conceal all conduits unless specifically indicated to be exposed. <br />3.Conduits in the following areas may be exposed,unless otherwise indicated: <br />a.Electrical rooms. <br />b.Mechanical equipment rooms. <br />4.Arrange conduit to maintain maximum headroom,clearances,and access. <br />5.Arrange conduit to provide no more than the equivalent of four 90 degree bends between pull points. <br />6.Arrange conduit to provide no more than 100 feet between pull points. <br />7.In every instance,conduit shall be installed in such a manner that the conductors may readily and <br />easily be drawn or pulled in without strain or damage to the insulation;and,also,so that defective <br />conductors may be readily and easily withdrawn and replaced by new conductors. Long radius bends <br />and a sufficient number of approved pull and junction boxes shall be approved for this purpose,and as <br />may be directed by the Engineer. All conduit shall be securely supported and grounded. <br />8.Arrange conduit to prevent moisture traps.Provide drain fittings at low points and at sealing fittings <br />where moisture may collect. <br />9.Where conduits join any couplings or threaded fittings,the ends shall be made watertight. <br />10.Maintain minimum clearance of 12 inches between conduits and hot surfaces.This includes,but is not <br />limited to: <br />H Conduit Support: <br />1.Provide all required hangers,supports,anchors,fasteners,fittings,accessories,and hardware as <br />necessary for the complete installation of electrical work. <br />2.Secure and support conduits in accordance with NFPA 70 and Section 26 05 29 using suitable supports <br />and methods approved by the authority having jurisdiction. <br />3.Provide independent support from building structure.Do not provide support from piping,ductwork, <br />or other systems. <br />Docusign Envelope ID: 2D852F9B-A7CF-462A-9536-444A53AA848A
