  Q. On SHA Contract No. AA4105174 on sheet 4 of 35 tells of area that gets flowable fill and box culvert and other pipe refer to Section 303 of 2001 Standard specifications. I read them and is it the excavated material we dig out used for backfill or Cr6 or #57 stone?
  A. Please refer to Section 303 of the 2001 Standard Specifications, which should be used to determine the type of backfill used for the pipe.

Inq. 3 Post Date:   12/22/2008 Inquiry Date:   12/22/2008
  Q. Can precast 32" F Shape Temporary Concrete Traffic Barriers be used on this project as an equal to the water filled barriers for maintenance of traffic?
  A. The water filled barriers are used to eliminate the need of placing crash cushions or end treatments, which would be necessary if the barriers were concrete. So the two are not equal. Also, since the temporary lane closure on MD 3B is only permitted from 9am to 3pm Mon. thru Fri., water filled barriers would be much easier for removing and resetting, while the temporary concrete barriers are for a relatively long-term closure set-up.
