616.8.1 Temporary Traffic Control for Contract Plan Sheet Development
Each work zone is different and requires different temporary traffic control (TTC) plans. For contract plan sheets, MUTCD (2009) Chapter 6H provides the typical applications (TAs) to develop TTC plans and for in-field modifications as directed by the engineer. TAs should be altered, when needed, to fit the conditions of the specific work zone. See EPG 237 for additional plan sheet guidance.
References to work vehicle or shadow vehicle made in the MUTCD will be considered incidental and should be indicated as such on the TTC plans.
When optional items are referenced in the MUTCD, the contractor may, at their discretion, utilize the items as incidental. When the TTC plans indicate one or more of these items as required for stationary work activities, applicable pay items will apply and will be included. Field adjustments, as directed by the engineer, may require additional pay items via a change order. When use of a Truck Mounted Attenuator (TMA) is deemed necessary for one or more stationary work activities, this will be indicated on the TTC plans, the Truck Mounted Attenuator (TMA) for Stationary Work Activities JSP will be included in the contract, and the Truck Mounted Attenuator pay item will be provided.
TMAs used in mobile operations, such as striping, are considered incidental per Sec 612.5.
616.8.2 Temporary Traffic Control for MoDOT Employees
If you have questions about a Typical Application, please email WZTAQuestions@modot.mo.gov
These TAs are intended for the use of MoDOT employees. Before each work shift, all employees are required to participate in a pre-shift safety briefing. During the briefing, the applicable TAs should be printed out and then discussed to know the procedures to follow for the day’s work. This should include the risk-based assessment (RBA). The TAs shown in the EPG are considered current.
