Plan Sheet / Specification Reference=Retaining Wall "331R" - shown on sheets 563 & 564 typical section on 563.  Retaining Wall "361L1" - shown on sheets 615 thru 618 - Typical section shown on 615.

Is ditch behind wall "361L1" a type A or B concrete channel as shown on sheet 349. Retaining wall quantities shown on sheet 533 do not include quantities for walls "331R" and "361L1" - What are the quantities?  Will this change the bid quantity? Where is colored ditch lining shown on drawings (Bid item # 186)?
 

  • Quantities for retaining walls "331R" and "361L1" are shown on plan sheet No. 533.  Due to the Design Sequencing bid process there will be no further information provided before bid opening.

Q:08/13/03
    R:08/21/03
    R:08/29/03
Plan Sheet / Specification Reference= Sheets 881,882

 These two sheets do not seem to coincide with the other sheets for this structure (Carmel Mountain Road OC).  Can you please supply the correct general plan sheets 1 and 2 for this structure showing the plan view and typical sections for stages 1 and 2 that match the rest of the plans. Without these sheets, we cannot determine the correct staging and removal sequence among other important details.  I understand that this is a design sequencing project.  Regardless, I would expect even preliminary design plans to include proper general plan sheets.  It appears as though the current sheets 881, and 882 were earlier design concepts for this structure because they only show two parallel superstructures rather than the three bridge design shown in subsequent sheets. The revision dates at the lower right of these two sheets seem to support this conclusion.  Given that general plan sheet three (sheet 883)shows the correct section, as do all the other sheets I would hope that the correct versions of the first two sheets are also available.  Additionally, please clarify which set of quantities are correct for this structure.  I assume that those on sheet 884 are correct not those shown on sheet 881.

  • Your comments have been noted.  A response to your comments is pending.
  • The bridge quantities shown on sheet 884 are the correct quantities for this structure. 
  • An addendum will be issued shortly updating plan sheets 881 and 882.

Plan Sheet / Specification Reference= Plan Sheets 574,575

 These two plan sheets refer to a portion of Wall "335L" which is shown in the structure plans. The structure plans do not show this portion of the wall.  Will the design of this portion of the wall be available before bid, or is this a part of the future design sequence?  Do the bid quantities for this wall on sheet 533 include amounts for this portion of this wall? If so, what design has been assumed to calculate those quantities?

  • The design of this portion of the wall will be part of the Design Sequencing bid process.
  • The quantities for this portion of the wall are not included on sheet 533.
  • The assumed design for this portion of the wall is a Type 5 Ret Wall.

  • 1. See response to inquiry No. 4.
  • 2. The backfill quantities for walls 322L, 327L, 335L, 353R, 357R, 357R1, 361L, and 361L1, shown on sheet 533, were calculated per the Standard Plans and Specifications.  Due to the Design Sequencing bid process there will be no further information provided before bid opening.

Plan Sheet / Specification Reference=Retaining wall quantities- sheet 533.  Bid item #186-colored ditch lining.

Ditch lining quantities for retaining walls 331R & 361L1 are not shown on sheet 533-
What are the ditch lining quantities? 
On what plan sheets is the colored ditch lining shown?  These questions were asked on inquiry #2, but not answered?

  • See response to inquiry No. 2. 
  • The ditch lining quantities for retaining wall 331R and 361L1 are  5.85 cubic meters and 11.5 cubic meters respectively.
  • No additional information will be provided regarding the colored ditch lining due to the Design Sequencing bid process before bid opening.

Q:08/25/03
    R:08/29/03
Plan Sheet / Specification Reference=Item 121 Structural Concrete Bridge at Carmel Mtn. Final Pay Qty of 4,000 M3
Plan Sheet 881 shows quantity for Bridge is 3,300 M3
Plan Sheet 884 shows quantity for Bridge is 4,000 M3

If you replace sheet 881 per question #5 then you would use the quantity of 4,000 M3 from sheet 884. However the quantity given on sheet 881 is actually closer to our take off. It seems there is some confusion on this bridge as to what is to be built and what quantities are correct. As this is a final pay item, it must be cleared up and time given to complete a reasonable take off in order to establish a fair unit price.

  •  See response to inquiry No. 5.

Q:09/03/03
    R:09/09/03
Plan Sheet / Specification Reference=59 Roadway Excavation

Typical cross-sections would indicate that portions of the
existing pavement will be removed as part of this project.  Is the
removal of pavements incidental to Roadway Excavation? 

  •   Yes, it is included in the volume of Roadway Excavation.

Q:09/10/03
    R:09/16/03
Plan Sheet / Specification Reference=

Specification Section 10-1.01 - ORDER OF WORK, paragraph 6 states that
"Locations of stationary work activities shall be limited to 5 nights in any
21 day period. Stationary work is defined as sand blasting, bridge deck
grinding, erection and removal of falsework and bridge demolition."

We are having a difficult time understanding what is trying to be achieved
with the above paragraph. By limiting the time period to "nights" we are
presuming the paragraph should be directly linked to when lane closures are
available, for the above referenced work, as defined in the special
provisions.

1:   We are interpreting a location to be defined by a specific lane
closure chart contained in the special provisions. Is this assumption
correct?

2:   Is the reference to "sand blasting" meant to be for all sand
blasting activities or is it referring to the sand blasting activities that
may require a lane closure?

  • 1. No (see response to Bid Inquiry No. 18). 
  • 2. It is meant strictly for sand blasting activities related with the planned stationary bridge/structure work.

Footing, sheet 850 of 972

Bid item 112, 600MM Cast-In-Drilled-Hole Concrete Piling, sheet 850 of 972
Stage Construction Traffic Handling Plan Stage 3C, Sheet 425 of 972
Question=Reference: Sheet 425 of the Contract Drawings (Contract 11-080904)

The work area described in section A-A is 4.9 meters wide.  The footing to
be built in this stage of the construction is 6.1 meters wide.

Is the stage construction plan going to be modified to provide sufficient
work area?  Or, is the footing and pile arrangement at this location going
to be modified to fit in the confined space?

  • The construction staging will no be modified since per plan sheet 425, section A-A, the total work area available is 4.9+0.6+0.6 = 6.1 meters.

Q:09/11/03
    R:09/17/03
Plan Sheet / Specification Reference=

Plans show 36-20A pole to be new or relocated.  Standard Plans (CT '99) shows either slip base or non slip base to be designated on plans.  This is not shown on plan.  Does the State want all slip bases?

Sheet 738 & 740 has a Note 3 with no legend. 
Sheet 743 has Notes 1, 2, 3 with no legend.  Can we find out what the State wants?  Sheet 762 shows to relocate a 15 pole and 3-1A poles.  The cost breakdown on page 281 shows to install 1-new 26 pole and 2-1A poles which is correct?
Page 302 Section 10-3.26 states State furnished video detection assemblies as in "materials".  Materials does not say video assemblies are State furnished.  Which is correct?
Bid item 244 "Communication Conduit Bridge" plan show 53C and 2-103C are we to bid a combined price for both?

  • Bid the bases as shown in the plans and specifications.
  • Bid the planed work shown on sheets 738, 740, and 743 as shown and per the specifications.
  • Video detection assemblies will be State furnished.
  • Yes,  a combined bid price for conduits varying from 53C to 103C per meter will be required.

Plan Sheet / Specification Reference=#188 Minor Concrete(Curb,Gutter,SW,DW)
#189 Minor Concrete (Textured Paving) (Gore Paving)

The bid quantity for #188 shows 280 m3, while the summary of quanity sheet Q-9 show 20.8 m3.  Which is correct and will the correct quatity be shown in a revised addendum?

For bid item #189 the summary of quantity sheet Q-9 shows 678 m2 for gore #2 on sheets L-6 & C-4 detail. This quantity does not reflect the calcuation of m2 based on the dimensions shown on C-1.  Will this be correct prior to bid date? 

  • The correct quantity  for contract item #188 is 20.8 m3 as shown on sheet Q-9. 
  • Bid contract item #189 as specified per  the plans and specifications. Due to the Design Sequencing bid process there will be no further information provided before bid opening.
