820 - Traffic Signals
It is the contractor's responsibility to notify MDOT’s Statewide Signal Shop prior to beginning any signal work. Traffic signal projects include a note in the project plans that state the following, "Contact MDOT (and any other maintaining agency) seven (7) working days prior to start of construction and seven (7) working days prior to signal activation.” Appropriate contact information is indicated in the plan notes. The seven day time frame will allow for coordination between the contractor and the Statewide Signal Shop for installation and inspection of traffic signal work. It is recommended that these notification requirements be discussed at the pre-construction meeting.
The Statewide Signal Inspector must be on-site to help to ensure that unsafe conditions with the traffic signals are not utilized or incorporated into the project work and to protect the safety of the public. Any work done incorrectly will need to be corrected at the contractor's expense.
If an inspector from MDOT’s Statewide Signal Shop or appropriate maintaining agency is not on site when a contractor is performing signal work, the project representative (MDOT/consultant engineer or inspector) should stop the signal work until verification of prior notice to MDOT has been confirmed. Construction staff should call the Statewide Signal Shop at 517-322-3360 to verify whether inspection notification requirements have been met. If prior notification was not provided by the contractor, form 1165, Notice of Non-Compliance with Contract Requirements is to be issued until the contractor properly notifies the Statewide Signal Shop and necessary inspection arrangements have been made.
