Maintain railings and walkways in good condition. The cross slope must be no greater than 1:50 (2 percent) and the running slope no greater than 1:20 (5 percent). Verify all new and used temporary railing elements comply with requirements for end connection and surface finish. Form CEM-2303, Temporary Pedestrian Access Route Sidewalk Detour Inspection Report, may be used by the engineer and the contractor to report weekly inspections if the temporary pedestrian access route is provided using an existing pedestrian route. Determine when the contractor must submit a construction contingency plan. Notify the district transportation management center when unforeseen traffic delays result from planned work. Do not hide the taper of a traffic control system behind a vertical or horizontal curve. The specifications require temporary traffic screen to have 3-foot-long openings spaced at 200-foot intervals. If new asphalt concrete joins existing asphalt concrete, the difference in texture and color between them creates a taper in the new traffic lane that may convey the wrong sense of direction, especially at night or in rain. Scheduled Times: 8:00 a.m. to 4:00 p.m. Expected Delay from Traffic Control due to Road Closure. In Part 4, identify a Caltrans project supervisor, usually the resident engineer or an assistant resident engineer. The resident engineer should determine which contractor activities might use COZEEP support. Facilitates review and approval of TMP measures and planned lane closure requests. 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. Also, when possible, use barrier vehicles or an impact attenuator vehicle between the approaching motorist and workers on foot. ROAD TYPE DISTANCE BETWEEN SIGNS A B C RURAL EXPRESSWAY / FREEWAY 100 350 500 1000 350 500 350 500 1500 2640 For speed of 45 mph or more, L = WS For speed of 40 mph or less, L = WS/60 * - For other offsets, use the following merging taper length formula for L: * URBAN - 25 mph OR LESS URBAN - MORE THAN 25 mph TO 40 mph URBAN - MORE THAN 40 . Determine the exact location of the temporary signs and when they are no longer needed for the direction of traffic. 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. When estimating COZEEP hours, take the following CHP operating policies into account: The detail estimate will show the initial funding level provided for COZEEP as supplemental funds for state-furnished materials and services. Inspect TPARs weekly to verify that they are clean and unobstructed and comply with the Americans with Disabilities Act and the work plan required by the specifications. Retroreflective sleeves on traffic cones. Caltrans attempts to maintain safe and convenient access for pedestrians and bicyclists, who are susceptible to disruptions because of their slower speeds and sensitivity to uneven surfaces, noise, airborne dust, road debris, and fumes. Any contractor requests for COZEEP that are denied by the resident engineer should be in writing to the contractor stating the reasons for denial of the COZEEP support. Additional signs ordered by the resident engineer are paid for as extra work. Remember that the motorist has no knowledge of the traffic control plan and is entirely dependent on the system for warning and guidance. Verify the contractor uses an impact attenuator vehicle as a shadow vehicle in moving closures and during placement and removal of components in stationary closures. The purpose of the gaps is to allow drivers and passengers of vehicles to get behind the barrier in case of a disabled vehicle. Containment may require modestly increasing the spacing between signs or require the placing of additional signs. Otherwise, Federal (MUTCD) codes are shown. Take special care to consider areas in schools or senior citizen center locations. Allow only one type of plastic traffic drum on the project. Verify removal of any temporary delineation that conflicts with any subsequent or new traffic pattern for the area. Verify the lights are not glaring into approaching traffic, especially truck traffic. Be aware that collision concentrations and inconvenience may occur with changes in direction, number of lanes, alignment, and speed. Anticipated length of time, rounded to the nearest 5 minutes, to pick up the closures. Verify that temporary traffic control devices comply with the contract requirements.

The special provisions provide detail for railroad requirements including contractors responsibilities with the railroads to move materials or equipment within the limits of the railroad property. The activities would, therefore, cause the closure to remain past the time allowed in the closure charts. A G20-2 "END ROAD WORK" sign, as appropriate, shall be placed at the end of the lane closure unless the end of work area is obvious or ends within a larger project's limits. While the Caltrans' charts did not explicitly dictate that a contractor must perform work during nighttime hours, the charts functionally required that any work requiring a lane closure could only be performed at night. Key personnel involved in traffic control have responsibilities as follows. Process, justify, and document the request the same way as any other fund request. QuickMap Know before you go. Require the contractor to anchor bases of traffic cones that do not have enough size and weight to keep the cones in an upright position. Acts as a resource for the resident engineer, the DTM, and the TMP manager during TMP implementation.
