AASHTO Green Book See Appendix F for additional guidance Work Zone Options GDOT will consider night work, full-closure, detours, temporary pavements, temporary structures, use of existing shoulders, on-site detours, etc. (See Appendix F for additional guidance) System Planning Strategies GDOT will consider grouping and sequencing of projects in a corridor; including the costs for work zone management strategies in plans. Design Strategies GDOT will consider traffic control, choice of materials, use of positive separation, and detour, temporary structures, temporary pavements [runaround], ramp closures, etc. (See Appendix F for additional guidance) Contracting Strategies GDOT will consider low bid, design-build, incentive/disincentive contracting, etc. Work Zone Management Strategies GDOT will consider use of intelligent transportation systems, traveler information & real-time work zone monitoring [Navigator], traffic incident management (HERO GDOT will consider use of enforcement but will consider implementation on a project by project basis. (See Appendix F for additional guidance) Agency Use of Work Zone Reviews, Process Reviews, or Safety Inspections/Audits The project engineer conducts work zone reviews as outlined in the Departments Construction Manual and specification 150. The contractor’s Worksite Traffic Control Supervisor [WTCS] conducts inspections according to the provisions of Specification 150. Process reviews are conducted on at least every two years in accordance with Title 23 CFR 630 Subpart J Strategy for Use and Collection of Work Zone Data The policy for the use and collection of data are documented in the Construction Manual General Provisions 150 and Section 17 and as outlined in Appendix Criteria for Identifying Significant Projects Responsibilities
for these projects as well. Reference significant project flowchart (Appendix C). A TTC plan be consistent with the provisions under Part 6 of the Manual on Uniform Traffic Control Devices (MUTCD) and with the work zone hardware recommendations in Chapter 9 of American Association of State Highway and Transportation Officials (AASHTO) Roadside Design Guide. The TTC plan may be incorporated in the TMP by reference, such as reference to elements in the MUTCD, approved standard TTC plans, State transportation department TTC manual, or be designed specifically for the project (specification 150). In developing and implementing the TTC plan, roadside safety hardware shall be maintained at an equivalent or better level than existed prior to project implementation. GDOT should coordinate with appropriate stakeholders in developing a TMP as per Public Involvement Guidelines (TOPPS 4055-1) The provisions for a TMP shall be included in the project’s Plans, Specifications, and Estimates (PS&Es). The PS&Es shall either contain all the applicable elements of an TMP, or include provisions for a contractor to develop a TMP. In the case of contractor-developed TMPs, the contractor will incorporate the minimum TMP requirements already developed by the GDOT during the planning process. The PS&Es for a design-build project may include the skeleton for a TMP, as developed by the GDOT in its planning process, and the provisions for completing TMP development under the contract. The GDOT must approve contractor developed TMPs and they shall not be implemented until approved. The contractor may submit an alternate sequence of operations as provided in specification 150. Pay item provisions for implementing the TMP shall be included in PS&Es, either through method-based specifications (pay items, lump sum, or combination) or performance-based criteria at the Department’s discretion. Examples of potential performance criteria include number of crashes in the work zone, incident response or clearance time, travel time through the work zone, delay, queue length, and/or traffic volume. The GDOT and the contractor shall each designate a trained person at the project-level who has the primary responsibility and sufficient authority for implementing the TMP. TMP Development
Design Include information in the concept report regarding the TMP. For a non-significant project, TMP requirements may be satisfied by the Special Provision Section 150 – Traffic Control document. Coordination between the PM and the Office of Construction is required to develop appropriate time restrictions for work. (See Appendix F for additional guidance) The PM will work with other offices and use the TMP checklist completed by the Office of Planning (or Maintenance/Traffic Operations depending on programming) to develop a TMP. Key information for the TMP will be included in the Project Concept Reports (i.e. a statements regarding PI, TTC, lane closures, detours, etc.). (See Appendix F for additional guidance) Construction Participate during concept development. Review the TMP and provide comments to the PM. Coordination between the PM and the Office of Construction is required to develop appropriate time restrictions for work. (See Appendix F for additional guidance) Same as a non-significant project.
