Verify Category 3 temporary traffic control devices are the type shown on the Authorized Material List for Highway Safety Features. If a change order modifies the plans, construction engineers should take steps necessary to verify that the modified plans are adequate to provide the highest level of traffic safety and service consistent with conditions actually encountered. Establishing continuity is especially necessary if previous traffic shifts have created confusing or conflicting diagonal joints and have eradicated pavement markings. Consider separating pedestrian movements from both job site activity and vehicular traffic. Invoices should include the agreement number and be submitted monthly in arrears, in triplicate, within 60 calendar days of date of service. Verify visibility and legibility requirements. At the end of the shift, the senior CHP officer onsite should estimate travel time and mileage for each officer from the project site to the CHP office. Time and mileage are based on officers starting and stopping times at their reporting station and include travel to and from the project. The maintenance person should have spare cones, signs, and barricades available to replace or restore system elements displaced or damaged by traffic.
