A Protection Vehicle may be fitted with a truck mounted impact attenuator. Work Area - The portion of the Highway closed to Public Traffic and set aside for workers, construction Equipment, and construction Materials. The Work Area is typically delineated by channelizing devices or separated from traffic using temporary barriers.
Traffic Control Devices, use and follow the most current versions in effect of the following:
Oregon Department of Transportation's Sign Policy and Guidelines for the Stat e Highway System The Manual on Uniform Traffic Control Devices (MUTCD) FHWA Standard Highway Signs manual ODOT Oregon Temporary Traffic Control Handbook for Operations of 3 Days or Less when directed by the Engineer only for mobile pavement marking operations or surveying Work, available on the ODOT Traffic Control Plans Unit website (see 00110.05(e)) ODOT Oregon Portable Changeable Message Sign Handbook , available on the ODOT Traffic Control Plans Unit website ODOT Traffic Control Plans Design Manual , ava ilable on the ODOT Traffic Control Plans Unit website
00221.02General Requirements - Provide and maintain all TCM. The Engineer may verbally or in
writing require immediate changes to the TCM being used on the Project. Immediately make these changes, as directed. Submit all proposed TCM revisions to the Engineer for approval.
Do not start Work on any stage of construction until the TCP has been reviewed and accepted and all TCM are in place and the TCP is operating satisfactorily. During constructi on, determine if TCM, in addition to those in place, are required and immediately notify the Engineer. Immediately make changes as approved or directed, but do not place or remove devices without prior approval.
00221.03 166 Work may be suspended as specified in 00180.70 or the TCM may be performed by the Agency if the Contractor fails to correct an unsafe condition. Costs for Work performed by the Agency may be deducted from monies due the Contractor.
