from the "S-4" Line and Section B-B on sheet 50 shows the traffic face of

to 2.4 m from the ETW on the right of the "S-4" Line and Section B-B on

Plan Sheet / Specification Reference=Item 44, Type 60Mod Concrete Barrier

Question=Location 9 SB:
1. The typical section for Location 9 SB on Sheet 4 for "SD-5" Sta 932+36 to
969+01 shows the traffic face of the Type 60C concrete barrier as 4.5m left
of the "SD-5" Line. The layout plans show offsets of 4.82m Lt (Sta 932+36)on
sheet 14, 4.90m Left (Sta 941+53 and 941+78)on sheet 17, and 4.90m Rt (which
should be Lt) (Sta 969+01) on sheet 20.  Per the typical section, the
barrier spans from 4.5m to 3.9m Lt of the "SD-5" Line which does not match
the layout drawing no matter what is used for the barrier layout line.
Please advise.
2.  What is used for the barrier layout line at this location?

   Q:09/18/07
  R:09/18/07
Plan Sheet / Specification Reference=Special provisions section 10-1.03 WPCP
and Special Provisions section 10-1.16 CLOSURE REQUIREMENTS AND CONDITIONS

Question=This is an "A + B" job, so time is of the essence.  There is a
maximum of 120 days allowed for construction, with a daily multiplier of
$14,100.  However, the provisions of section 10-1.03, (WPCP) allow the
Resident Engineer 15 days to review the WPCP submittal and unlimited to the
time to review any necessary corrections and total discretion as to any
impact on the progress of the job.  With $14,100 per day hanging in the
balance, these vague definitions of time durations and sequencing are
unreasonable.  In the matter of section 10-1.16, (CLOSURES), there is a
requirement that closures necessary to perform the work planned under this
contract shall be submitted not less than 25 days before the anticipated
date of operation.  As there is virtually no work that can be done without
such a closure, this could add 25 days (or $352,500)to the job. Further
adding to the concern in this area, the time intervals between bid date,
award date, and approval date are undefined, totally within the discretion
of Caltrans, and are currently unpredictable.  All combined, these
conditions seem inconsistent with the "fast-trak" philosopy.
  • Your input is appreciated and will be conveyed to other departments.

Plan Sheet / Specification Reference= Concrete Barrier, Type 60C

Question= Ref: Your response to previous pre-bid inquiry # 13- The response you have provided to a  reasonable request, is vauge, and does not clarify the current ambiguity of contract requirement for Type 60C concrete barrier.

Additionally, request that you provide details so that correct evaluation can be made for quantity of concrete, reinforcing steel requirements to comply with note 9 on Standard Plan A 76A, and methods of construction, all of which are not determinable by your current incomplete contract infromation.
