Caltrans should order early pickup only when traveler and worker safety will not be compromised. If the portable transverse rumble strips become out of alignment or skewed by more than 6 inches, have the contractor readjust them to the original location. TMPs should be consistent with the Final Rule guidelines for developing and implementing the policy. Supporting justification for use or nonuse of COZEEP should be documented in Category 21, Construction or Maintenance Zone Enhanced Enforcement Program, of the project files. During night operations, the vehicles should have their headlights turned off and their hazard lights and flashing amber lights turned on. Verify temporary flashing beacon systems are relocated as work progresses according to the specifications. When an AFAD becomes inoperable, notify the contractor to immediately replace it with an identical device, use a flagger with the appropriate-size advance warning sign and gate cones as shown in Standard Plan T13 or stop all construction activities that require the device to be in operation. Caltrans Transportation Management Plan Guidelines provides more information on the recommended level of detail for TMPs. Verify the temporary flashing beacon system includes a backup power source and automatic transfer switches. Confine the work area to as short a distance as practical. Remind the contractor of Americans with Disabilities Act requirements if the traffic control system will affect pedestrian traffic and a temporary pedestrian access route is needed. The cost estimate should include an estimated number of COZEEP service hours and travel time converted into an equivalent dollar cost. The reviewer should determine that the plan can be implemented and that it adequately facilitates the movement of trafficincluding bicycles, motorcycles, and pedestrians. Request a list of Category 2 temporary traffic control devices to be used on the project and copies of their Federal Highway Administration (FHWA) acceptance letters. Use Form CEM-2302, Temporary Pedestrian Access Route Weekly Inspection Report, to document that TPARs are maintained in compliance during the course of work. (Under ideal conditions, all advance warning signs and the taper would be in a tangent with the taper placed on a slight upgrade for improved visibility.). Compute the payment as a force account or as an adjustment of compensation based on a force account analysis. The selected speed should be what a driver exercising due care would drive in normal conditions of light and weather. They are not detectable by persons with visual disabilities. Anticipated cooling times needed for asphalt concrete pavements before opening a lane, shoulder, or ramp to public traffic. Notify the district transportation management center when unforeseen traffic delays result from planned work.

Figures 6H-28 and 6H-29, Sidewalk Detour or Diversion, and Crosswalk Closures and Pedestrian Detours of the California MUTCD are examples for accommodating the needs and control of pedestrians. Also, verify that flagging stations are laid out correctly, are visible to approaching traffic, are illuminated during nighttime, and have correct advance warning signs. The resident engineer must email service requests, daily reports, cancellation forms, and tracking spreadsheets to the COZEEP coordinator on a monthly basis. Calculate the adjustment on a force account basis. Based on traffic counts, the district traffic operations office determines times for closures and for night work. Check that all crash cushion modules are filled with the proper weight of sand. Check construction area signs often during the course of the work. Construction situations frequently require a lateral shifting of traffic in relation to the normal path of travel and may involve dropping a lane. The activities would, therefore, cause the closure to remain past the time allowed in the closure charts. Timelines for the contractor and the engineer to meet at the job site, review progress, and forecast when work will be stopped to open the lane, shoulder, ramp, or route to the public. The following guidelines apply to the color and texture of pavement surfacing materials: The following guidelines apply to speed zones: Frequently, special provisions restrict work on the existing traveled way to a specified period at night. On every project that requires the contractor to close traffic lanes, the project engineer should assess the need for COZEEP as part of the projects safety review, constructability review, or both. Time and mileage are based on officers starting and stopping times at their reporting station and include travel to and from the project. To confirm that contractors can access LCS and LCS Mobile, do the following before work begins: https://dot.ca.gov/programs/construction/training.

Make sure that the contractor places the portable radar speed feedback sign systems as shown on Standard Plans T18, T19, T20, and T21 and as far from the traveled way as practical, where it is visible and legible to approaching traffic, taking into account any vertical or horizontal roadway curvatures. Caltrans and the CHP have an interagency agreement that is the basis for the Construction Zone Enhanced Enforcement Program (COZEEP). Confirm the contractor places portable flashing beacons according to the plans and removes them from the traveled way at the end of each nights work. Review the requests to avoid oversights and overbooking. If a contractor is unable to access the LCS Mobile web page, obtain the closure status from the contractor and notify the transportation management center. Verify the base is shaped to prevent rolling if struck by vehicles. Work with the DTM to verify that project activities conform to the TMP, contingency plans are implemented when necessary, and disruption to the traveling public is minimized and does not exceed limits established in the TMP. An inevitable degree of mismatch between the old and new surfaces creates a slight discontinuity that may cause a car to lurch or swerve. Verify construction area signs are from a commercial sign manufacturer and have a Type 3 or higher grade retroreflective sheeting. 555 were here. Obtain from the contractor, the completed Form CEM-2311, Temporary Pedestrian Access Route Contractor Compliance Report, within 2 business days after construction of a temporary pedestrian access route. If an impasse occurs, the district COZEEP coordinator and the designated CHP division office contact should act as the second level of review. Perform additional reviews periodically throughout the construction project, since changes may affect the facilitys effectiveness. The state representative assigned to the project should make sure the local agency resident engineer performs the duties as outlined above. Review Sections 12-4.04, Temporary Pedestrian Access Routes, and 16-2.02, Temporary Pedestrian Facilities, of the Standard Specifications for the temporary pedestrian facilities requirements.
