Provide conduit <br />expansion joints where conduit crosses building expansion joints. <br />Q.Electrical contractor shall provide all sleeves, nipples, and opening required for the installation <br />of conduit. Sleeves shall project 2” above and below the floor. Conduits entering below the <br />water table shall have compression gland fittings for the purpose. <br />R.Liquid tight flexible metal conduit with PVC coating shall be used to make the final connection to <br />all equipment subject to rotation, vibration, or noise. <br />DocuSign Envelope ID: ECCAC5A0-6CC8-4B37-8AD3-89D69F0AE1AE
