Within the same working day, replace all existing beam guide rail or cable guide rail that is removed. Where possible, install new beam guide rail exposed to approaching traffic before the removal of the existing system. Before driving or mounting the posts, determine the location of utilities that may conflict with the posts. The Contractor may adjust post spacing by 6 inches, as approved, to eliminate such conflicts. After completing the wiring for each electrical system and before making connections, perform the following tests on each circuit using suitable equipment in the presence of the RE: 1. Tests for continuity. 2. Tests for ground. 3. Tests for insulation resistance between circuit wires and from circuit wires to ground. Verify that the insulation resistance is at least 150 megaohms between conductors, or between conductor and ground for circuits with a total single conductor length of 1,500 feet or more, and at least 175 megaohms for circuits with a total single conductor length of less than 1,500 feet. The RE may require additional tests if it is suspected that conduit have been damaged. Locate and repair damage to the electrical conduit due to construction operations. Drive beam guide rail posts to the required position. Ensure that posts are driven plumb, properly spaced, and to the line and grade shown. Attach the beam guide rail element to the blockout at every post. Align the top edge of the beam guide rail element in a straight line or smooth curve, parallel to, or concentric with, the traveled way. Where a vertical transition is required, ensure that the top edge of the beam guide rail element forms the chords of a smooth vertical curve. If adjustments to the rail element are necessary, obtain RE approval before punching, drilling, or reaming

that the top edge of the beam guide rail element forms the chords of a smooth vertical curve. If adjustments to the rail element are necessary, obtain RE approval before punching, drilling, or reaming of the rail element. Do not cut or weld the rail element. Install flexible delineators with white retroreflective sheeting on the right side of the direction of traffic. Install flexible delineators with yellow retroreflective sheeting on the left side of the direction of traffic. Mount flexible delineators on the blackout of beam guide rail using either a “U" channel base on the I-beam blockout or a flat base attached to a wood timber or synthetic routed blockout. Attach the base to the I-beam, wood timber blockout, or synthetic routed 39
