2025 STANDARD SPECIFICATIONS FOR CONSTRUCTION AND MATERIALS CATEGORY 100 PRELIMINARY SECTION 104 — MAINTENANCE OF TRAFFIC
104.00 General
This Section sets forth the traffic control requirements necessary for the safe and continuous maintenance of traffic throughout the area affected by the work and is intended to minimize inconveniences to the traveling public, while providing for the safety of motorists, pedestrians, and workers. Maintain vehicular and pedestrian traffic on or along any transportation facility as specified in the Contract Documents. When speed of traffic is noted, this means the posted speed or prevailing travel speed, whichever is higher, unless otherwise specified. All applicable Maintenance of Traffic equipment shall conform to NCHRP Report 350 and/or MASH 2016 criteria for Test Level 3. When no longer needed, remove items used for temporary maintenance of traffic from the project site. All removed items shall become the property of the Contractor, unless otherwise specified. Ensure that at least 90 percent of all reflective barrier markers, warning lights, and raised pavement markers are operational at any given time. Correct deficiencies within 24 hours after notification. Upon initial installation, temporary traffic control signs shall have at least 70 percent of the reflectivity specified in 950.03 over 90 percent of the reflectorized surface. Channelizing devices shall have at least 80 percent of the reflectivity specified in 950.03 over 90 percent of the reflectorized surface. Replace damaged traffic control signs within four hours of notification. Take necessary corrective action, as approved, to adequately warn and protect the public until the signs are replaced. The Contract Documents will specify one or more of the items listed in the following sections. When work is specified to be accomplished under the Maintenance of Traffic item, the work will be incidental to the Contract price for Maintenance of Traffic.
104.01 Traffic Control Plan (Tcp)
CATEGORY 100 PRELIMINARY SECTION 104.01 — TRAFFIC CONTROL PLAN (TCP)
104.01.01 Description
Develop and implement a TCP. The TCP will include the design and placement of items such as signing, pavement markings, delineation, channelization, barriers, crash cushions, and other items as required. TCPs may be implemented within a single project or jointly between two or more projects. In situations where TCPs are jointly implemented, ensure that correct and nonconflicting guidance is presented to the traveling public. Prior to commencement of Contract work, the successful bidder shall complete a Traffic Control Plan Certification. Indicate whether the Administration's TCP will be implemented (Option 1), the Administration’s TCP will be modified (Option 2), or a TCP will be developed (Option 3). Submit the TCP in writing to the Engineer at least 20 days prior to starting any work. Submit changes to the approved TCP in writing at least five days prior to implementing the change. For emergencies, the approval process will be completed within four hours. All changes to the TCP shall be approved in writing by the Engineer prior to implementation. Submit for approval supporting documentation containing an assessment of safety and mobility impacts of the modified or proposed TCP. Contact the Engineer to determine what level of detail and types of analysis are required for the assessment. No work shall begin until the required traffic control patterns and devices are in place. Refer to Contract Documents for Work Restrictions. When TCP Option 2 or Option 3 is selected, the following shall apply:
a.Plans and revisions to plans shall be drawn to the same degree, likeness, and sophistication as that of the Contract Plans.
b.Submittals shall be on sheets measuring 22 in. x 34 in. with a standard margin and a standard title block at the lower right corner approximately 4 in. x 8 in., or on 8- 1/2 in. x 11 in. paper with a 1 in. margin and a title block. Include the following information in the title block and in the order listed.
1.Name of Contractor (and subcontractor, if applicable). (2) Address of Contractor (and subcontractor, if applicable). 2025 STANDARD SPECIFICATIONS FOR CONSTRUCTION AND MATERIALS
