The interface switches will be powered by 120 volts AC in each traffic signal cabinet, available from an outlet strip/expander on the interior wall of each cabinet. The outlet strips are part of each MDT-supplied signal cabinet and do not need to be provided by the contractor.

Under the Special Provisions, SEQUENCE OF OPERATIONS talks about lane closures may be restricted during peak hours if deemed necessary by the Project Manager. Peak hours are between 7:00 am and 9:00 am and between 4:00 pm and 6:00 pm. If we are shut down during that time for 4 hours a day, would this still be a contract day?
Answer
Submitted: Wednesday 20-MAR-2019 10:38 AM
Lane closure restrictions are not anticipated to be a regular occurrence. However, the restrictions may be enacted if traffic becomes congested such that the continuous flow of traffic through the work zone is not maintained, causing an unreasonable inconvenience to the travelling public. Assessment of contract time will be determined on a case-by-case basis depending on how the restrictions impact the Contractors scheduled work.

1) There seems to be discrepancies between special provision 24.B.11) where it says to limit the street corner ADA locations disturbed to 8 corners, special provision 46.B. where it allows 6 trips for signal activation, and special provision 48.E.4) where it says to have a minimum of 4 signalized intersections complete and ready for turn on prior to the arrival of the representative from the Traffic Engineering Section.
2) What constitutes "disturbed"? The presence of traffic control devices, unfinished concrete work, non-functioning pedestrian pedestals and signals?
3) How can the contractor determine where work can be performed by the general contractor and all subs with the limitations placed in the following?
a) SP 48.E.4 - 4 Intersections at a time.
b) SP 46.B.- Allow up to 6 trips for signal turn on which permits 2 intersections at a time.
c) SP 24.B.20) - Construct signal improvements on all four corners of an intersection concurrently.
d) SP 24.B.14) - Digout work to be performed one quadrant at a time at 27th and 3 Ave. North.
