Committee approves $12,000 temporary video detection after pavement saw-cut severs signal loops
Summary
Contractors repairing Manchester–Taylor sidewalks and curbs inadvertently severed signal induction loops; the committee approved a change order of up to $12,000 to install temporary video detection until the permanent signal equipment is installed later this spring or summer.
The committee approved a change order not to exceed $12,000 to install temporary video detection at two Manchester–Taylor intersections after construction saw cutting severed signal induction loops that had provided vehicle detection.
Public works staff reported that contractors performing sidewalk, hydraulic and pavement work on Manchester Road cut through pavement loops at the signalized intersections; with the loops severed the signals were operating on a fixed (pre-timed) schedule, causing unnecessary delays. Staff recommended a temporary fix—video detection cameras—until the permanent signal cabinets and new signal equipment are installed later in the year.
Kirschner Electric provided a quote for installation of temporary video camera detection; staff said the quote was reasonable compared with industry tabulations. Committee members asked whether the cost should fall to the contractor who performed the saw cutting; staff replied that the saw cutting was part of the contract work and that the temporary detection item was not included in the original contract pay items; staff said the city could have included a pay item for temporary detection but did not. Committee members discussed rental versus purchase and the short-term benefit of removing the pre-timed operations.
The committee approved the change order by voice vote (one recorded opposition was noted during roll call). Staff described the temporary cameras as rental/temporary equipment that would be removed when the permanent signals are installed.
Ending: Staff will issue a change order to the contractor to fund the temporary video detection up to $12,000 and will coordinate removal when permanent signal equipment is installed.
