Sheet 17 of the plans shows a cold milling limit detail. This detail shows milling on an approach street off of mainline with a note that the distance to be determined by the project manager. The project summaries and details do not specifically give cold milling and asphalt paving quantities nor do they indicate the number of approach streets to be milled and paved.
1) Could MDT please provide the number, location, cold milling quantity and asphalt paving quantity for the approach streets?
2) Also, are these quantities already included in the bid item quantities?

As a follow up to my question #5 concerning milling and asphalt paving on approach streets. MDT's response stated that all public approach streets will be milled and paved. Based on what I can see with the snow it appears that almost all the alley's within the project limits connect to Park Street or Excelsior Street with asphalt paving. Will the public alley's with existing asphalt paving also be milled and paved? If so, how many?

Public alleys will not be milled and paved. Sidewalk-alley intersections are to be constructed per the sidewalk details shown in the plans. Remove and replace asphalt in alleys adjacent to new concrete at back of sidewalk per the Street Excavation Limits Detail and Street Replacement Detail provided on Sheet 17 of the plans. The intent is to provide a 2' asphalt transition behind new sidewalk for matching into existing asphalt and providing space for formwork. Quantities for Plant Mix Bit. Surf. and Crushed Agg. Course are provided in the summary frames for information only.
