Verify that the contractor schedules and conducts a meeting to discuss the operation of impact attenuator vehicle as required under Section 12-3.23A(4), Quality Assurance, of the Standard Specifications. Review with the contractor how flaggers will communicate with each other, with pilot cars, and with workers inside the controlled area. Consult with the district traffic engineer for other acceptable means to protect the sign instead of the Type K temporary railing required by the specifications. If there are questions as to flagger competency, contact your construction safety coordinator to have them come and observe the flagging operation. Verify the pavement is clean and dry and the contractor places the channelizers during conditions that meet the required temperatures. The special bulbs used with solar signs have much narrower beams than conventional bulbs and, therefore, require greater care while being aimed. Do not allow the use of commercial pallets that exceed the maximum height. Check pallet heights when used. Verify that temporary pavement marking tape to remain in place more than 14 days is applied according to the specifications, and that temporary pavement marking tape to remain in place 14 days or less is applied according to the manufacturers instructions. Request a certificate of compliance for Type K temporary railing.

Frequently, the plans for stage construction, detour, or traffic handling will require arrays of temporary crash cushion modules. Traffic control costs in support of extra work are to be paid as part of the extra work. Confirm the contractor uses the long-term temporary pavement marker for 180 days or less and the short-term temporary pavement marker for 14 days or less. Verify that additional speed limit signs indicating the reduced speed limit are placed within the construction work zone as specified. Verify visibility and legibility requirements. Registered professional engineer with more than 20 years of experience; Temporary Traffic Control (TTC) and Flagging instructor at UC Berkeley Tech Transfer Program; Technical member of the National Committee on Uniform Traffic Control Devices Do not allow the application of temporary pavement delineation over existing pavement delineation. Check the contractors layout work. 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. The following guidelines are for measuring and paying for various traffic control devices for construction areas.

If the bid item is not included in the project, process a change order to provide a TPAR. The cost of covering, uncovering, and removing signs (when they are no longer needed) is included in the contract price for construction area signs. Extend the straight section, known as the tangent portion of the closure, to better position the taper. Trainings below are not facilitated by Caltrans, and Caltrans is not responsible for any contents provided through those trainings. Obtain a weekly temporary automated end of queue warning system operations report. Require the contractor to set up an off-the-highway detour before closing all ramps in both directions of travel at the same interchange.
