Verify that portable flashing beacons comply with the requirements in Section 12-3.31, "Portable Flashing Beacons," of the Standard Specifications. How the contractor will meet the projected rates for material delivery to the job site. The invoice backup will include the COZEEP service summary and copies of cancellation notices. The activities would, therefore, cause the closure to remain past the time allowed in the closure charts. To confirm that contractors can access LCS and LCS Mobile, do the following before work begins: https://dot.ca.gov/programs/construction/training. Count the plastic traffic drums for payment as they are placed in the locations shown on the plans. Geometrics for a transition at the end of a high-speed approach should be better than those adequate for a situation within the work zone. Acting as a resource for the resident engineer, construction engineer, DTM, and TMP manager during TMP implementation and reviewing the contractors construction contingency plan. Verify that pedestrian facilities comply with the Americans with Disabilities Act. The traffic control plan should be appropriate for anticipated conditions that may occur during construction. If the portable signal system is out of operation, the contractor must provide flaggers to control the traffic until the traffic signals are in operation. Provides pedestrians with a reasonably safe, convenient, and accessible path that replicates, as nearly as practical, the most desirable characteristics of the existing sidewalks or footpaths. Verify that traffic handling devices meet the visibility and legibility requirements. When possible, implement temporary speed limit reductions in conjunction with a COZEEP operation. Pedestrians, including persons with disabilities, need to be accommodated through and around work zones. If automated flagger assistance devices (AFAD) bid item is not shown on the bid item list, providing AFAD is change order work. Category 2 devices include barricades and portable sign supports. Allow only one type of plastic traffic drum on the project. The contractor develops a construction contingency plan to identify activities, equipment, processes, and materials that may delay reopening of closures in the event of failure or breakage. 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. Verify no-passing zone signs are removed when no longer required. M1. Verify that pallet height is 4 inches or less. Extend the straight section, known as the tangent portion of the closure, to better position the taper. If the contractor is to place the traffic control system repeatedly in the same place, the contractor can request to mark on the shoulder the locations of advance warning signs, cones, and drums. Links: Lane Closure System (LCS) Mobile Statusing Instructions This training will take approximately 30 minutes to complete. Do not use the contract item for temporary crash cushion modules to pay for temporary crash cushion modules that are placed to fulfill the requirements of the Public Safety section. Consider separating pedestrian movements from both job site activity and vehicular traffic. When construction affects the pedestrian facility, the contractor should maintain a continuous unobstructed path connecting existing accessible elements, such as parking lots, or bus stops through the project. Such conditions may alter the apparent pattern of the roadway and cause an eradicated line to appear to be a lane line. Verify portable flashing beacons operate according to the specifications. Verify telescoping flag trees are from a commercial-quality material manufacturer. Include the district TMP manager, the DTM, and the public information officer as appropriate in preconstruction or work planning meetings. Verify that the contractor is prepared to comply with TMPs related to work performance. Shift traffic to one side or the other, but do not split it into two traffic streams. All drums should use the same type and brand of retroreflective sheeting. Determine the methods and equipment the contractor will use for closing lanes, ramps, and roadways, and for flagging and controlling one-way traffic. Imposing a 24-hour-a-day regulatory speed reduction can be difficult to justify and obtain approval for. Obtain a sample of the type of portable delineator to be used on the project. CalTrans Lane & Road Closures SR-38 East / West Active Thu Mar 2 2023, 6:01AM Lasting 14 hours One-Way Traffic closure lasting 14 hours on Conventional Hwy for Emergency Work affecting #1, Right Shoulder lane (s) in District: 8 From: Old Mill Creek Rd Mentone to Jenks Lake Rd Angelus Oaks View on Google Maps ID: C38EA-0004-2023-03-02-06:01:52 Consideration for worker safety and the safe movement of traffic through work zones starts with planning. Document why an item does not comply with the ADA checklist in Category 46, Assistant Resident Engineers Daily Reports, of the project records. Verify that the contractor constructs permanent new facilities and alterations to existing facilities in accordance with the contract plans and specifications. Caltrans lane closure charts - vaau.talkwireless.info CalTrans Lane & Road Closures SR-14 North Wed Mar 1 2023, 9:01AM Lasting 6 hours Full closure lasting 6 hours on Off Ramp for Road Maintenance affecting All lane (s) in District: 7 From: Antelope Valley Freeway, Route 14 Newhall to Placerita Canyon Rd Newhall View on Google Maps ID: C14CA-0003-2023-03-01-09:01:00 Wed Mar 1 2023, 9:01AM Withhold some payment from progress pay estimates to cover the cost of removing temporary crash cushion modules. When conditions prevent starting the temporary surfacing at a square joint on the existing pavement, a treatment such as a light sand seal can establish the continuity of the traveled lane. Verify the contractor offsets the approach end of Type K temporary railing by 15 feet minimum from the edge of an open traffic lane, according to Section 7-1.04 Public Safety, of the Standard Specifications. Lane Closures Emergency closures can be searched under District or Statewide. When planning for pedestrians in work zones, verify that the contractor does the following: When existing pedestrian facilities are disrupted, closed, or relocated, the temporary facilities should be detectable and include accessibility features consistent with those in the existing pedestrian facility. Make sure that portable transverse rumble strips are placed before closing the lane to traffic. 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. The California MUTCD Sign Charts contain commonly used signs in California, and is not meant to be used as a comprehensive or stand-alone design tool. Impact attenuator vehicles are paid for as part of the contract item for the traffic control system. The project engineer should consult with the resident engineer to determine which specific construction operations should use COZEEP and use that as the basis of the initial funding. The request has been submitted in a timely manner. Provide the contractor with the internet link to access the LCS web-based training. Most parts are self-explanatory. @CaltransDistrict7 crews are working to clear the roadway to make it safe for travel. This section provides guidelines for inspecting temporary traffic control devices in construction areas. Compare the traffic control plan to site conditions. Inspect crash cushion modules to confirm they comply with the specification and manufacturer requirements. The project engineer should include adequate COZEEP funds in the project estimate. 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. Provide the contractor with the message content and the thresholds used for triggering when the messages will be displayed. Use Form CEM-2302, Temporary Pedestrian Access Route Weekly Inspection Report, to document that TPARs are maintained in compliance during the course of work. Make every effort to resolve disputes at the lowest level such as between the resident engineer and the CHP coordinator at the local CHP area office. Request an impact study for ramp closures of short duration where the possibility of adverse results or sufficient public concern exists to identify effects on adjacent businesses. In Part 4, identify a Caltrans project supervisor, usually the resident engineer or an assistant resident engineer. Perform additional reviews periodically throughout the construction project, since changes may affect the facilitys effectiveness. the lane closure unless the end of work area is obvious or A G20-2 "END ROAD WORK" sign shall be placed at the end of lane closure during hours of darkness. 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. The ideal transition is on a horizontal tangent with a slightly rising grade at the end of a level approach. When severe congestion is forecast because of capacity reductions, include plans for using the media to notify the public, Construction Zone Enhanced Enforcement Program (COZEEP) services, alternate route development, metering by upstream ramp closures, changeable message signs, radar feedback speed signs, highway advisory radios, and monitoring the end of the traffic queue. Remind the contractor of the requirement to complete the LCS web-based training. In addition, it is recommended that Construction field staff take the online training every 3 years as a refresher. Automated flagger assistance devices (AFAD) can be used in place of flagger to remove workers from the roadway to improve worker safety from traffic. During these reviews, examine the locations of planned roadside obstacles as well as protective safety devices, signs, striping, detours, falsework, temporary railing, attenuators, and clear recovery zones. Review the specification requirements and sheet T4 of the Standard Plans. Verify attendance of subcontractors and other contractors personnel involved with traffic control.
