Allow only one type of portable delineator on the project. Do not sever or move a pedestrian route for nonconstruction activities such as parking for vehicles and equipment. Section 12, Temporary Traffic Control, directs the contractors attention to the. Obtain from the contractor, the completed Form CEM-2312, Temporary Pedestrian Access Route Contractor Weekly Report, within 2 business days of completing a weekly inspection. Reducing standards on existing roadways, such as sharpening curves and shortening auxiliary lanes, can adversely affect operating characteristics. Critical work activities are those performed in a closure that would render any portion of the traveled way unsuitable for public traffic use. Verify that crash cushion module arrays are installed according to the manufacturers instructions. Calculate the adjustment on a force account basis. All traffic control devices should conform to Section 12, Temporary Traffic Control, of the Standard Specifications. View from List View from Map One Stop Shop Traveler Information link for Western US states: California, Oregon, Nevada and Washington. Obliterated traffic stripes and markings should not be visible to drivers as pavement delineation during the day, at night, and under all weather conditions. Next install the first sign drivers will see in approaching the work area from the affected direction. Temporary pavement markers will not adhere to a cold in-place recycling surface. Check that the sign complies with the visibility and legibility requirements. CHP policy and the COZEEP agreement require that a sergeant or higher ranked officer be assigned to oversee COZEEP officers if there are more than 4 officers assigned to a project. If the contractors activities interfere with vehicular or pedestrian traffic, contact the contractor and request correction of the deficiency. 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. The effectiveness of handling traffic through night construction depends on the contract plans and the details of the contractors activities. TMP strategies are designed to maintain additional delays below this maximum threshold, that is, less than 15 or 20 minutes. The reviewer should determine that the plan can be implemented and that it adequately facilitates the movement of trafficincluding bicycles, motorcycles, and pedestrians. Make the environment like the approach highway. When an operation is terminated before the time the specifications allow because of circumstances beyond the contractors control, consider granting time, compensation, or both, within the terms of the contract. Alert Caltrans Traffic Map Chain Control Map Route Conditions State Route Closures CHP Incidents TMC ALERT Interstate 10 (I-10) is closed between Route 86 and Route 177 due to storm damage. Also, when possible, use barrier vehicles or an impact attenuator vehicle between the approaching motorist and workers on foot. Determine when the contractor must submit a construction contingency plan. Category 3 devices include crash cushions, impact attenuator vehicles, temporary railing, temporary barrier, and end treatments for temporary railings and barriers. PCMS are working equipment when actively displaying a message, otherwise they are nonoperating. 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. Design for the speed that vehicles will travel. It is not necessary to restudy impact previously studied during planning and design unless significant commercial development has occurred in the area in the interim. Verify the contractor removes traffic-handling equipment and devices from the job site when they are no longer needed for controlling traffic. Reviewing periodically the traffic control setup for each work zone and discussing any deficiencies with the resident engineer. To protect the highway during construction, improvement, or maintenance operations. Observe the flagging operation to verify that flaggers are using the correct procedures for directing motorists in accordance with California Code of Regulations, Title 8, Section 1599,(8 CCR 1599) Flaggers, and Chapter 6E, Flagger Control, of the California MUTCD. Verify temporary pavement markers are the same color as the lane line or centerline markers being replaced. Verify visibility and legibility requirements. Reviews the TMP and traffic contingency plan for constructability issues. Lane Closure System (LCS) Mobile Statusing Instructions This training will take approximately 30 minutes to complete. Confirm cone locations are straight and spaced in accordance with sheet T9 of the, Confirm that all flaggers are clearly visible to traffic and their positioning is safe and effective. As funding and operations allow, consider providing COZEEP for the following situations: Generally, COZEEP is not necessary when only one lane is closed on freeways with four or more lanes in the same direction of travel. Require proper maintenance of plastic traffic drums. Verify the lights are dimmed at night and set on bright during daylight hours. Caltrans should order early pickup only when traveler and worker safety will not be compromised. Verify channelizers used for temporary edge line delineation are predominantly orange and the surface- mounted type. 2. Sometimes through traffic tends to follow an exiting vehicle. If the portable transverse rumble strips become out of alignment or skewed by more than 6 inches, have the contractor readjust them to the original location. For guidelines on publicizing information, refer to Section 1-206, Relations With the Media and Traveling Public, of this manual. In the daily report, enter a description of the services the CHP provided, such as traffic breaks, stationary patrol upstream of the work area, or circulating patrol, and complete the CHP officer and CHP vehicle information. Closures are reported and managed using the web-based Lane Closure System (LCS) Mobile application. Also refer to Section 2-2, Traffic, of this manual, which provides guidance and a general overview of providing a safe and convenient passage of public traffic through the construction area and is complementary to this section. The following is a list of CalTrans lane closures, road construction, and blocked lanes that are active or plannded for on Highway SR-17 Updated Mar 02, 2023, 9:33 AM CalTrans Lane & Road Closures SR-17 Verify all new and used temporary railing elements comply with requirements for end connection and surface finish. SEE NOTE 2 END ROAD WORK G20-2 B 100' 10-20-10 48" x 24" 237 Direct the contractor to provide PCMSs for use not otherwise provided for in the contract, with a minimum notice of 1 full working day. Verify that pallet height is 4 inches or less. The resident engineer must email service requests, daily reports, cancellation forms, and tracking spreadsheets to the COZEEP coordinator on a monthly basis. Adjustments should be made to create adequate sight distance, to avoid locations that require drivers to make multiple decisions, to accommodate expected queues, and to coordinate activities at multiple locations. Include these considerations for conditions requiring minor changes in the field: The following guidelines apply to crossover transitions: For temporary modifications of existing ramps, review acceleration and deceleration lanes. If the screen blocks motorist visibility, order its removal and consult with the district traffic engineer concerning alternatives. Contact the district traffic engineer for recommendations if the clearance to the traffic lane cannot be obtained. Dated photographs or video recordings, particularly of points of transition, may be especially valuable. The path must be stable, firm, and slip resistant. Certain equipment, such as dike placement machines, can only operate off one side of the equipment and may need to be operated against live traffic. The contract item price includes the costs of maintaining, replacing, and repairing channelizers. Traffic queuesContain traffic queues completely within the advance warning signs of any closure. Caltrans is working to clear the roads in order to reopen them. A maintaining traffic standard special provision allows assessing the contractor a contract payment deduction for the value of a traffic delay when the contractor exceeds the closure window. (Under ideal conditions, all advance warning signs and the taper would be in a tangent with the taper placed on a slight upgrade for improved visibility.). Review the closure requests for compliance with the closure requirements charts and other contract requirements. In many cases, placing a PCMS behind existing guard railing will protect it. Confirm that AFAD are placed in accordance with the plans and where clearly visible to the AFAD operator and to approaching traffic. The area where the surfacing joins the existing roadway can be critical. Review the specification requirements and sheet T4 of the Standard Plans. Midblock worksites should not cause pedestrians to skirt the worksite or make a midblock crossing. Do not allow the use of sandbags. If properly shielded, most lights can be mounted on construction equipment. 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. The following elements affect the drivers ability to navigate the intended path: Pavement surface condition, texture, and color. Obtain a copy of the manufacturers instructions for the portable transverse rumble strips. Initial placement of each barricade is paid for as a contract item at the time of placement. LAKESIDE. Mn/DOT allowable lane closure chart example (9)16 Figure 11. Closures that will reduce horizontal or vertical clearances require even more notification. 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. Confirm portable signal systems comply with the requirements in Section 12-3.33, Portable Signal Systems, of the Standard Specifications. The change order that authorizes the extra work should reflect these costs. Do not allow the application of temporary pavement delineation over existing pavement delineation. Stationary closures on a traffic lane are 10-97 before placing the first cone on the traffic lane, and 10-98 after removing all the cones from the traffic lane. The project engineer should include the project estimate funds necessary to provide COZEEP as state-furnished materials and services. Check construction area signs often during the course of the work. During the course of work, monitor the contractors activities to verify closures are statused in LCS as follows: The LCS will notify the resident engineers and designated inspectors by email when the contractor changes the status of a closure. Time and mileage are based on officers starting and stopping times at their reporting station and include travel to and from the project. When the officer or officers arrive at the project site, the senior CHP uniformed officer will check in with the Caltrans project supervisor who should initiate Form CEM-2101, COZEEP Daily Report. The daily report number will also be the project identifier number. If the operation is terminated before completion of the planned work because of circumstances within the contractors control or because of equipment breakdown, do not allow compensation and charge a working day as appropriate. 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. If the contractor requests usage of alternative temporary crash cushion modules, verify that their proposed modules are on the Authorized Material List for Highway Safety Features. Chapter 4: Construction Details, Section 12: Temporary Traffic Control. Provide the following information to the district railroad liaison agent who will forward it to the Public Utilities Commission: If construction involves structure work, send a copy of the above information to Structure Design. Moving closures are 10-97 before the actual start time of the closure, and 10-98 after the actual end time of the closure. Check for live traffic conditions. Refer to Section 5-1.20 Coordination with Other Entities, of the Standard Specifications, if applicable, and the special provisions. Create a physical facility that will encourage motorists to appropriately guide their vehicles on the intended path of travel and make it possible for the vehicle to perform as intended. If the opening has a drop off behind it that might present a hazard to the public, document in the resident engineers daily report an exception to the Standard Plans note and have the contractor close the gap for public safety purposes. Move the workers and equipment onto the closed lanes only after all system components are in place. This will speed the placing of closures and allow for a more consistent taper alignment. Confirm that lighting intensity complies with the Cal/OSHA requirements. Verify that the contractor is prepared to comply with TMPs related to work performance. To sign up for the training, submit a training request in Staff Central for this course by following the instructions on the Division of Construction's How to Request Training intranet page. Review the project plans and sheets T1A, T1B, and T2 of the Standard Plans. Verify the temporary flashing beacon system includes a backup power source and automatic transfer switches. Try to eliminate surprise elements from temporary roadways. Both the senior officer and the project supervisor should sign the completed COZEEP daily report. Retroreflective sleeves on traffic cones. The local CHP contact person will note in the cancellation form if Caltrans is being charged a cancellation or 4-hour overtime fee. Before making a decision to approve a change order that would result in a prolonged ramp closure, weigh the results of the study with factors, such as construction costs, travel costs, delay, and safety. Construction area signs, except those used in traffic control systems for closures, are paid for as a lump sum item. Also confirm it in writing using Form CEM-2103, COZEEP/MAZEEP Cancellation Form. Once contact is made, the CHP coordinator will return the completed cancellation form. Verify portable radar speed feedback sign systems comply with the requirements in Section 12-3.37 Portable Radar Speed Feedback Sign Systems of the Standard Specifications. Unknown time of reopening. When necessary, ask the contractor to adjust placement or message content of signs based on changing project or traffic conditions.
