Plan Sheet / Specification Reference=X-section sheet x-2,3,4 and detail
sheet c-3

Question=The placement of the aerially deposited lead appears to extend
beyond the pay limits for excavation as shown on sheets x-2,3 and 4. Is
it Caltrans' intent to over excavate the roadway in order to place the
aforenmentioned soil? If so, is this quantity accounted for and will be
paid for in Bid Item 29?

  • Yes and yes.

Plan Sheet / Specification Reference=Section 4 (page 102)
Section 10-1.37 (page 186)-Pavement Concrete Mix Proportions  and Field
Qualification

Question=The contract specifies a 50 Day Completion time as well as
commencement within 90 days of the contract approval. The submittal
process in Section 10-1.37 could be 90 days or longer even if a
re-submittal is not required. With the fair and racing season from June
4th thru September 4th (with a 13 day break in between), was it Caltrans
intent to not begin this project until near the end of these event
seasons due to ramp closure restrictions? If not, will Caltrans waive
these submittal requirements and/or accept submittals prior to Contract
Approval?
  • Please bid per the current contract documents.

   Q:02/27/07

   R:02/28/07
Plan Sheet / Specification Reference=Plan Sheets SC-1 thru SC-12

Question=It appears from the layout of the Stage Construction Drawings
and the Layout that it was the intent of the designer to commence and
complete the concrete paving and associated work (sawcut, remove
AC/Concrete, excavation, placement and compaction of lead deposited
soil, aggregate base, asphalt base, jointing, 10-day curing, profiling,
and grinding) in the 14-day allotted time frame for the closure of the
ramps. Is this accurate?
  • Yes
Also, what it the intent of the designer to close both ramps at the same
time?
  • Due the two ramps sharing the same Closure Chart, does not mean they have to be closed concurrently.
With a bid date of March 1, 2007 and a NTP around mid-April (?) the ramp
closures would be necesary during the Del Mar Fair time frame (June 4
thru 18) and/or the Del Mar racing season (July 4 thru September 4).
What was the intent in this case?
  • Please bid per the current contract documents.
