643.3CONSTRUCTION —Install top and side delineators as shown on the Standard Drawings . Install
warning lights as directed and according to the manufacturer's recommendations. Maintain alignment, delineation, warning lights, and condition of the barriers as necessary, for the duration of the project. Remove the barriers from the project upon project completion, or when directed. To minimize eradication of paint lines within the work zones, paint continuous white or yellow 6 -inch-wide pavement marking on the barrier as shown on the Standard Drawings. Water blast the temporary barrier with a minimum of 3,000 p ounds per square inch before painting and if applicable, remove existing contrasting paint color .
in BC -719M and as directed by the Representative .
anchors is structurally sound and free of cracks in the vicinity of the anchor to be installed. During the initial barrier layout, use a metal detector specifically designed for locating steel in concrete to minimize conflicts with existing steel reinforcement. Move the barrier parallel to the direction of traffic up to 2 inches and perpendicular to traffic up to 1 inch if conflicts with the existing steel reinforcement occur. Maintain a smooth barrier face to traffic along the entire barrier length . Use a rotary drill and bit for drilling the hole for a 1 -inch diameter bolt. Drill into the deck using the holes in the temporary barrier as a template. The drill may be located anywhere within the 2 -inch slot but must be maintained vertically ( ± 1º) and at a 5º cant ± 1º to the vertical from the front face to rear face of the barrier. Drill into the deck using methods that will not shatter/damage the concrete surface adjacent to the holes or result in concrete spalling at the underside of the deck. Notify the Representative if spalling occurs. Patch areas of spalling immediately. If reinforcement is encountered during drilling, before the specified depth is attained, notify t
