Maintenance of Traffic (MOT). The Design-Build Firm shall be fully responsible for the MOT on public streets, detour of traffic (including furnishing and maintaining regulatory and informative signs along the detour route), traffic control, and other provisions, throughout the Project, as required by the Manual of Uniform Traffic Control Devices (MUTCD), and FDOT Roadway and Bridge Standard Index drawing Book. Traffic shall be maintained according to corresponding typical traffic control details as outlined in the previous noted standards. No street shall be completely blocked, nor blocked more than one-half at any time, keeping the other one-half open for traffic, without specific approval. If required by the Project Manager, Traffic Division or FDOT or as otherwise authorized by the Project Manager or Consultant, the Design-Build Firm shall make arrangements for the employment of uniformed off-duty policemen to maintain and regulate the flow of traffic through the work area. The number of men required and the number of hours on duty necessary for the maintenance and regulation of traffic flow shall be provided by the City of Miami Police Department. The Design-Build Firm shall provide all barricades with warning lights, necessary arrow boards and signs, to warn motorists of the Work throughout the Project. Adequate approved devices shall be erected and maintained by the Design-Build Firm to detour traffic. Excavated or other material stored adjacent to or partially upon a roadway pavement shall be adequately marked for traffic safety at all times. The Design- Build Firm shall provide necessary access to all adjacent property during construction. The Design-Build Firm shall be responsible for the provision, installation and maintenance of all MOT and safety devices, in accordance with the Manual of Uniform Traffic Control Devices (MUTCD) and FDOT Roadway and Bridge Standards index drawing book. In addition, the Design-Build Firm shall be responsible for providing the Project Manager with MOT plans for lane closures and/or detours for approval. These plans (sketches) shall be produced, signed and sealed by a professional Engineer registered in the State of Florida, employed by the Design-Build Firm and certified under FDOT Procedure NPIL No. 000-000-000. Where excavations are to be made in the vicinity of signalized intersections, attention is directed to the fact that vehicle loop detectors may have been embedded in the pavement. Verify these locations by inspecting the si...
Maintenance of Traffic (MOT). M.O.T. will be used to cover basic costs associated with set-up and maintenance of Construction and Detour Signing, Barricades and Warning Lights for traffic for most speed humps and speed table installations. This pay item is intended to cover costs associated with advance warning signs and cones used during each construction project. M.O.T. will be authorized on a Project-by- Project basis. Detail No. 5 outlines the typical 2-lane 2-way Traffic Control Plan. Some Projects may require a different M.O.T. plan. These will be negotiated in a project-by- project basis.
Maintenance of Traffic (MOT). A Maintenance of Traffic (MOT) plan was created to control and manage traffic during the construction. Sub-project #1 was designed and documented for bid in the late 1990s, but not bid on at the time due to budget constraints. The design documentation was not revised for this bidding due to the perceived lack of value in time and cost of performing a new design. The MOT plans are guided by traffic counts. If there are over 1,500 cars per hour, then the State standards required two lanes to be open for traffic at all times if possible. A second guideline is where lanes transition from one side of the highway to the other. The state suggested a construction sequence that could be used to determine the transitions based on the vertical and horizontal distances and contour measurements. The contractor had to formally request any changes to the MOT plan in the design if they felt it was not adequate. The high amount of businesses and traffic in the area led to a high traffic flow. Thus, lane transitions with closures, rather than detouring and diverting traffic to other roadways, were considered because of these potential influences to the commercial area. Meanwhile, the real time traffic count shown that over 1,500 cars per hour passed through the area during the daytime while the volume was much lower during the night. At least two lanes were required to keep the traffic flow according to state standards. However, the lane transitions in the bid documents would not work because the contours onsite differed from what was in the plans. This meant that the transitions could not be done according to standards at the locations in the original designs since the elevation changes were too great. The work to get the MOT plan within standard meant that traffic could not be transitioned as planned, and thus traffic was adjacent to workers when the plan originally called for traffic to be transitioned away from them. The proposed phases of the job also did not work with the depth profiles of the utilities, and thus the CM had to rework this plan as well. The CM said that this also affected the MOT plan, as utilities had to go in at times that were not ideal for where traffic was at that time. Once the decision was made, the owner wanted work to occur in certain areas while crews were mobilized in the vicinity. This consideration led to a decision that sub-project #2 should be combined in order to make management and coordination easier for the state’s PM. This decision ...
