Add the following subsections

611-6.2.1 Responsibility for maintenance of existing traffic signals during construction:

The contractor is responsible for all maintenance of the traffic signal at commencement of the project. The maintenance of the traffic signal is defined as repair and/or replacement of any equipment or hardware failures which cause the traffic signal to operate abnormally. This will include any damage caused by accident or criminal behavior to any underground or aboveground traffic signal related facility. Once the replacement signal is operational, the responsibility for maintenance of the new traffic signal will continue to be the responsibility of the contractor until all of the discrepancies or punch list items have been corrected and the traffic signal has obtained final acceptance. The contractor will be required to respond to any traffic signal complaints from citizens, law enforcement and/or The City of Plant City's call center.

611-6.2.2 Responsibility for maintenance of a new traffic signal: The contractor is responsible for all maintenance of the new traffic signal from the moment the construction starts until all discrepancies or punch list items have been corrected and the traffic signal has obtained final acceptance. The contractor will be required to respond to any traffic signal complaints from citizens, law enforcement and/or The City of Plant City's call center.

611-6.2.3 Contractor's responsibility during the warranty period: The warranty period of 90 days commences after the 48-hour burn-in of the traffic signal. This is defined as 48 hours after the new traffic signal is fully activated. If a new signal is turned on prior to all functions of the traffic signal being fully serviceable, the warranty period will begin when the traffic signal has completed final acceptance. As an example: a new traffic signal that is replacing an existing traffic signal may have to be activated due to MOT reasons prior to the pedestrian signals being functional. In this case, the 90-day warranty period will commence when the pedestrian signals, all noted discrepancies and any other item not functional have been fully activated, have been corrected, and/or are fully functional. If the maintenance responsibility of the traffic signal has been turned over to The City of Plant City during the warranty period, the contractor will be responsible for the provisions identified in Section 611-6.2 of the Florida Standard for Road and Bridge Construction and as amended herein.

During any period when the contractor is responsible for maintenance of the signal, the contractor will respond to a reported traffic signal failure or operational problem within two hours. If the contractor fails to respond within the allotted period and the City responds to the failure or operational problem, the contractor is subject to back charges for the City's expenses.
