Inquiry #2: A - On Plan Sheet SC-11, bottom of the plan sheet is noted "Stage 4B" while it is also stated to construct this work at "end of Stage 2 before moving southbound lane to Stage 3 configuration".

Inquiry #4: Traffic Control Clarifications Needed:

A - The traffic control staging, when all overlaid together, does not completely address the asphalt paving at Route 20/Market Street. SC-9 indicates Stage 4 at this location but does not fully extend to cover the work shown on L-1. Should this work be covered in Stage 4? Please clarify.

B - At River Road, the same problem with the cold plane overlay scope (as shown on L-1)... No traffic control staging covers this work. Stages 3 4 and 6 all end at 54+82.82 as shown per the various staging construction plans and do not encompass the cold plane overlay scope. Will this be done with moving lane closures or..? Please clarify.

C - At Route 20, B Line from Station 92+50to 97+59.18 the cold plane RHMA overlay scope (L-9 and L-10) are also not covered by traffic control staging plans. The Cold plane RHMA overlay from 97+59.18 heading south to project limits is covered by Stage 2 traffic control staging plans but stops at 97+59.18... Should this work be covered in Stage 2? Please clarify.

Response #2:
A. - Construction and paving operations at Route 20/Market Street are split between Stages 3, 4, and 6.

B. - The work in question is for cold plane and overlay as part of the minor street pavement conform. This work is intended to be completed with the placement of the final pavement. See Note 1 on sheet SC-1. Cold plane and overlay work can be done with moving lane closures consistent with the Special Provisions.

C. - Cold plane and overlay between these station limits is intended to be performed at the end of Stage 6. Per Note 1 on sheet SC-1, final pavement lift shall be placed just prior to final pavement delineation. The final pavement delineation between these station limits will not be able to be placed until the end of Stage 6 due to temporary striping necessary through Stage 6.
