Automated End Of Queue Warning System (Type 1) Day] Could you please provide some additional detail on system schedule/phasing or if multiple systems will be utilized simultaneously? If only one system is to be utilized could you provide detail on anticipated schedule or number of relocations? Thank you!
Inquiry submitted 01/16/2022
Response #1:Your inquiry has been received and is being reviewed. Thank You for your patience.
Response posted 01/17/2022
Response #2:
Automated End Of Queue Warning System (Type 1) Day is required when using either Table A or Table B and also required 24/7 at the location where there are only 3 lanes open to traffic.
If Contractor chooses to complete work at the location requiring the long-term closure first before moving into the slab replacement work, only one end-of-queue system is needed and can be relocated and repositioned where the work zone is.
During long term closure, one end-of-queue system setup can be used for all the Stage-Phase construction work.
During slab replacement, the number of relocations is dependent on the Contractor’s work scheduling, the number of times Tables A & B are used, and dependent on the Contractor’s production rate. Contractor can schedule work in a way where only one end of queue system is needed and can also control the number of times it needs to be relocated which is again dependent on the production rate or process. The peak hour period for this freeway segment begins at 0500 in the southbound direction and at 0600 in the northbound direction on weekdays (Mon-Thu).
