Contract 06-0H7304

The responses to bidder's inquiries, unless incorporated into a formal addendem to the contract, are not a part of the contract and are provided for the bidder's convenience only. In some instances, the question and answer may represent a summary of the matters discussed rather than a word-for-word recitation. The availability or use of information provided in the responses to bidder's inquiries is not to be construed in any way as a waiver of the provisions of Section 2-1.03 of the Standard Specifications or any other provision of the contract, the plans, Standard Specifications or Special Provisions, nor to excuse the contractor from full compliance with those contract requirements. Bidders are cautioned that subsequent responses or contract addenda may affect or vary a response previously given.


Q1) The Engineer's Estimated quantity for Item 32 appears to include the length of the Terminal Sections (175') which are paid under Items 33 & 34.

A1) The lengths of the Terminal Sections should be subtracted from the Metal Beam Guard Railing quantity. Terminal Sections will be paid under Items 33 & 34.


Q2) All call-outs for the Irrigation Crossover Extensions say "See Sheet C-1." There is no detail on Sheet C-1 for this work. Please provide the detail for the Irrigation Crossovers.

A2) Bid as you see it per plans and specifications.


Q3) At Sta. 358+37.20 there is a call-out that reads "End MBGR, End Cap Ty A, Connect to Conc Barrier." Where does this MBGR start? Why is it needed if the proposed Concrete Barrier is continuous in this location?

A3) The call-out on sheet L-4 "End MBGR +37.20, END CAP (TYPE A), (CONNECT TO Conc BARRIER)" should be removed.


Q4) On Sheet L-6 at approximately Sta. 402+50 (Left) there is a Survey Monument shown. Is this to be installed on this project? There is no bid item for the monument.

A4) Survey monument shown is an existing monument that is outside the work area. No installation or restoration required, hence, no bid item.


Q5) Will project cross sections be made available for bidding?

A5) Yes, the project cross sections are available at:

MJ's Copycats
5096 N. Blythe Suite 115
Fresno, Ca
Phone: (559) 271-7848


Q6) There is no K-Rail shown at the Willow Avenue, Barstow Avenue, Bullard Avenue and Villa Avenue Overcrossings. These structures will be exposed to traffic from the time the existing MBGR is removed until the Barrier is constructed. Will the K-Rail, Channelizers, and Crash Cushions required here be paid under Items 11, 13 and 14?

A6) The existing MBGR should not be removed before the concrete barrier is constructed. At some point, structures at those locations will be exposed to live traffic but during lane closures windows only. If the contractor elects to clear and grub the area including removing the MBGR before constructing the concrete barrier thus exposing the structures ouside lane closures windows, then the contractor is required to protect these structures by installing Temp railing, Crash cushion and channelizers at his own expense.


Q7) Barrier is shown on both sides of the freeway on cross sections, sheet 3,4,5, but not shown on layout pages. Quantites also contradict cross sections for barrier lengths. Please clarify.

A7) Alignments A1, A3, and A5 cross over the Route 168S centerline from left to right. Stationing is shown beneath each cross section of alignments A1,A3, and A5 on sheets 3,4,and 5. Stationing to the left of the Route 168S centerline refers to the cross section left of the Route 168S centerline, stationing to the right of the Route 168S centerline refers to cross section right of the Route 168S centerline. Follow the layouts L-1 through L-6 (sheets 6 through 11) for median barrier lengths and their sum total.


Q8) Will the state consider allowing lane closures on the West bound side to allow for the necessary barrier connections?

A8) Bid as you see it. Per Special Provisions page 58, "If minor deviations from the lane requirement charts are required, a written request shall be submitted to the Engineer at least 15 days before the proposed date of the closure. The Engineer may approve the deviations if there is no significant increase in the cost to the State and if the work can be expedited and better serve the public traffic.".


Q9) Please confirm that for Item 35 you are requiring costruction of a "Modified" Type 60 concrete barrier, which must have scupper openings at 25'-0" centers in all barrier. Additional individual scuppers also appear to be needed at sag locations. This seems to be your intent per notes 1 and 2 on Sheet 15 of 34, but the bid item and Special Prvision only define Standard Type 60 barrier.

A9) Concrete Barrier Type 60 is shown on sheet 27 (2006 Revised Standard Plan RSP A76A), sheet 14 (Construction Details C-1), and sheet 15 (Construction Details C-2). Sheet 15 shows scupper (typical) and scupper (sag locations). Refer to notes on sheet 15 for requirement for scupper spacing throughout the Concrete Barrier (Type 60) and the spacing adjustment required at sag locations (sag locations require a spacing adjustment but do not require an additional scupper).


Q10) There is an existing french drain system in the center median from Herndon to Willow. How will this affect the project?

A10) Existing drain pipe from Herndon to Willow will not be affected by the project. It is shown in drop-out but is not legible. West of Willow pipe was shown with dashed line to be legible because the installation of MBGR posts must avoid the drain pipe.
