950.3CONSTRUCTION—

Standard Drawings, and as follows:

• Existing traffic signals are to remain in operation until the new traffic signal equipment and devices are in place and operable unless indicated otherwise. If it becomes necessary to turn off the existing system of signalization, obtain the District Traffic Engineer’s approval, municipal concurrence, and provide flaggers or other approved means to direct traffic within the intersection during periods when the traffic signals are not operating. Place temporary poles to support existing traffic signals, as indicated or directed. Provide certification to the Department for temporary poles.

• Revise the existing traffic signal system, as indicated or directed.

• Before ordering any traffic signal or sign support poles, or performing excavations for these poles, perform the following preparatory activities:

ͦ Perform required actions according to the provisions of PA One Call, “Pennsylvania Underground Utility Line Protection Law Act 50”. ͦ Locate and mark existing underground utilities in the field. After completing the location and marking of the known utilities, field review the proposed pole locations with the Representative to ensure that no utility conflicts exist. ͦ Adjust pole locations as necessary to avoid utility conflicts and provide documentation so the final as-built plans can reflect the changes. ͦ Schedule and perform this preparatory work considering the time duration for pole orders to be fulfilled.

• For existing traffic signal supports labeled for removal on the plans, removal includes attached traffic signals, flashing warning devices, lane control signs and signal equipment.

• Removed traffic signal equipment is owned by the municipality or permittee, as indicated. Store removed traffic signal equipment on the project site. Maintain removed controller assemblies as a unit. Do not damage items during removal and storage. Prepare a list of the removed traffic signal equipment and provide the list to the municipal owner or permittee. For equipment wanted by the municipal owner or permittee, deliver the equipment to their storage area. Dispose of all removed equipment not wanted by the municipal owner or permittee.

• Abandon underground conduit, conductors, and detectors not interfering with new construction. Remove foundations and junction boxes that are designated to be abandoned and are located in an “off traveled roadway” area, to 1 foot below final grade, and dispose of removed materials. Fill, compact, and landscape the resulting hole, including topsoil, if necessary, by the particular planting.

• Repair damage to galvanized finishes.

• Restore areas damaged by construction.

• Identify vegetation that is blocking the visibility of traffic signals or signs. After obtaining approval from the Representative, remove or relocate vegetation that is blocking visibility. Removal or relocation of vegetation is incidental to the work specified in Sections 951, 952, 953, 954, 955, 956, 957, and 958.

• If not notified by the Representative, notify the Representative as soon as it is recognized that a utility facility is causing, or will cause, an obstruction to visibility.

• Before the initial turn-on, verify for the Representative that all traffic signals are working properly. Make the initial turn-on to flashing mode and full operation in the presence of a representative of the District Traffic Unit, municipality, and manufacturer(s) between the hours of 9 AM and 2 PM, Tuesday through

Thursday except holidays, or the day before or after a holiday . Under special circumstances , where necessary to ensure the safety of the motoring public, the Representative may grant exceptions to this rule. Notify the District Traffic Unit a minimum of 7 calendar days before the initial turn -on. For locations presently unsignalized, flash signals for a period of 3 to 7 days before full operation. If approved, the duration of flashing operation may be 3 to 5 days provided that it includes a minimum of 2 weekdays before beginning the normal stop-and-go mode of operation.
