The cost of covering, uncovering, and removing signs (when they are no longer needed) is included in the contract price for construction area signs. Check sign posts to confirm compliance with breakaway features. These Standard Specifications sections apply to pedestrian facilities: Verify that the contractor adheres to the following: At the preconstruction conference, discuss the need for temporary pedestrian facilities and ADA requirements. PCMS can be used in place of an advance flagger to remove workers from the roadway to improve worker safety from traffic. For public safety, when flaggers are not shown on the plans or specified and when ordered by the engineer, providing flaggers is change order work for which Caltrans pays 100 percent. Retroreflective bands on portable delineators. When full use is not possible, accommodate traffic by verifying a continuous roadway throughout the length of the project, achieved by using one or a combination of the following: The newly constructed highway or portions of it, A detour where traffic, including pedestrians and bicycles, is diverted over a temporary roadway, Passage of traffic through the work in progress. Use the standard formula for taper length shown in the California MUTCD or in the projects traffic control plan details. Request the user interface software and provide it to the Transportation Management Center for installation. Verify temporary pavement markers comply with Section 81-3, Pavement Markers, of the Standard Specifications, except for the waiting period before placing pavement markers on new asphalt concrete. Inspect the signs and equipment the contractor proposes to use, at the contractors or subcontractors yard if possible, before their first use. Document the reasons for COZEEP use. Obtain a copy of the manufacturers operating instructions. Provide protective overhead covering as necessary to protect from falling objects and dripping from overhead structures. District Construction should request an impact study for proposed prolonged ramp closures not formally considered in the planning or design phase. Also, verify that flagging stations are laid out correctly, are visible to approaching traffic, are illuminated during nighttime, and have correct advance warning signs. In accordance with the agreement, cancellations received less than 24 hours before work is to begin will be charged a cancellation fee of $50. Verify that the contractor has all components on hand before setting up any traffic control system and that all components meet the specifications requirements. Caltrans requires TMPs for all planned activities on the State Highway System. Where the prevailing speed of the approach is limited by alignment, the design speed should be equal to the prevailing speed of the approach roadway. Verify that construction area signs are placed outside the traveled way, do not block or protrude more than 4 inches into bicycle and pedestrian routes, and comply with Americans with Disabilities Act requirements. Confirm that the temporary roadway is engineered to the same design considerations as those in new construction: Geometrics of alignment and roadway section, Surface of the traveled lanes and shoulders or marginal areas. The maintenance person should have spare cones, signs, and barricades available to replace or restore system elements displaced or damaged by traffic. Confirm temporary flashing beacon systems comply with the requirements in Section 12-3.34, Temporary Flashing Beacon Systems, of the Standard Specifications. The Code of Federal Regulations, Title 23, Section 630, Subpart J, Work Zone Safety and Mobility, (23 CFR 630 Subpart J) requires Caltrans to adopt a policy that implements TMPs on all federally funded highway projects. The resident engineer administers the COZEEP program on the project. Initiate and obtain CHP sign-off of Form CEM-2101, COZEEP Daily Report. At the end of each day, report to the district COZEEP coordinator the COZEEP services used during that week. Additional devices are placed in sequence, moving in the direction of the traffic flow. Require the contractor to set up an off-the-highway detour before closing all ramps in both directions of travel at the same interchange. If a change order is processed that requires COZEEP support, and it is estimated that existing state-furnished materials funding for COZEEP is not sufficient, include additional funding for COZEEP as part of the change order. BOX 942874, MS-32 SACRAMENTO, CA 94274 PHONE (916) 653-0548 Making Conservation TTY 711 a California Way of Life. For changes to the district-approved traffic control plans on contracts administered by others, use the same review and approval process established for Caltrans-administered construction contracts. Information such as lane closure charts and road user costs will be added to the TMP once the project moves into the . Retroreflective sleeves on traffic cones. Determine the exact location of the temporary signs and when they are no longer needed for the direction of traffic. File formats include CSV, JSON, TXT and XML. Similarly, certain striping operations require the operator to operate against live traffic because of clearances. Use the most current edition of the American Traffic Safety Services Association (ATSSA) publication Quality Guidelines for Temporary Traffic Control Devices and Features to confirm acceptability of traffic control devices. Flashing beacons shall be placed at the locations indicated for in size and shall be orange or fluorescent red-orange in color. If you cannot contact the local CHP coordinator in advance and the officer reports for duty, the fee will be equal to 4 hours of overtime pay and mileage incurred, if any. Include appropriate signage. The contingency action plans should include detailed operations undertaken in case a major activity passes the late-finish milestone. Pallets that exceed this height raise the sand in the crash cushions above an acceptable level. Confirm the contractor provides a temporary pedestrian access route (TPAR) nearby, off the traveled way, when the construction activities require the closure of an existing pedestrian route. Inspect Category 2 temporary traffic control devices to confirm they are labeled with the FHWA acceptance letter code and the name of the manufacturer. Caltrans began a major project to retrofit the San Francisco-Oakland Bay Bridge to current seismic design standards in summer 1998 and expects to complete the work by winter 2014. . Verify that portable delineators meet the dimension requirements. TMPs should be consistent with the Final Rule guidelines for developing and implementing the policy. Construction activities such as night paving may be a deciding factor when the operation requires a large number of trucks into and out of the work area. Determine if the temporary traffic control devices to be used are on the Authorized Material List for Signing and Delineation Materials and if they require a certificate of compliance. To avoid having to obtain more than one speed reduction order per project, verify that the limits requested in the order cover the maximum distance where reduced speed would be required at any time during the life of the contract. If closure of an existing pedestrian route is required because of the contractors means and methods, remind the contractor of their responsibility to design and construct a TPAR at their expense, and obtain authorization to proceed with the work activities. 4-1202C (1a) Lane Closure System 4-1202C (2) Temporary Pedestrian Access Routes 4-1202C (3) Bridge Cleaning and Painting Activities 4-1202D Temporary Pavement Delineation 4-1202D (1) Temporary Pavement Markers 4-1203 During the Course of Work 4-1203A Flagging 4-1203B Temporary Traffic Control Devices 4-1203B (1) Traffic Cones Verify the contractor removes traffic-handling equipment and devices from the job site when they are no longer needed for controlling traffic. The status in LCS will change to APPROVED. The LCS will notify the contractor by email of the approval or rejection. When multiple projects in one area occur at the same time, require contractors to coordinate their efforts by resolving schedule conflicts before submitting their schedules for closures, and verify there are no closure conflicts before implementation. Consult your district COZEEP coordinator for a current estimate of hourly and mileage COZEEP cost. 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. Verify that portable flashing beacons comply with the requirements in Section 12-3.31, "Portable Flashing Beacons," of the Standard Specifications. Contractors are required to request closures using the Caltrans Lane Closure System (LCS) and status closures using the Lane Closure System Mobile web page. When portable signal systems are used in forests or grasslands, confirm adherence to all fire safety requirements. Before opening a roadway to unrestricted public traffic, the final delineation must be in place on the roadway either by using long-term or short-term temporary delineation or channelizing devices. of the lane closure unless the end of work area is 48" x 24" as appropriate, shall be placed at the end A G20-2 "END ROAD WORK" sign, with minimum size of the locations indicated for lane closure during Each flag shall be at least 16" x 16" in size with at least two flags for daytime closure. The contractor bears costs and expenses for additional support from the CHP, and Caltrans deducts associated costs from monies due the contractor. Verify that all the necessary signs, cones, drums, and other equipment are on hand before the system is set up for the first time. Refer to Section 12-4.02C(10), End of Queue Monitoring and Warning With Truck Mounted Changeable Message Sign, of the revised, Multiple closures and inter-project coordinationAvoid multiple closures with overlapping sign patterns. Questions? GIS Maps. Verify the contractor cements the bases of channelizers used for temporary edge line delineation as specified. Consideration for worker safety and the safe movement of traffic through work zones starts with planning. Withhold some payment from progress pay estimates to cover the cost of removing Type K temporary railing.
