Inquiry submitted 08/14/2012

Response #1:Please refer to Page 1 "NOTICE TO BIDDERS" in the Contract Special Provisions which states, "A Mandatory prebid meeting is scheduled for this project at 10:00am, on August 28,2012 at California Department of Transportation, District 7, 100 Main Street, 1st Floor Room 01.037, Los Angeles, CA 90012.

Inquiry #2: All the sound walls on this project at Empire Ave., Burbank Western Channel, SW# 1584, RW# 1604, RW# 1610, RW# 1630 and RW# 1662 all have "H"'s equal to 14'-0" or 16'-0". This "H" height is measured from the bottom of the 3'-0" barrier to the top of the sound wall. The problem is when you subtract this 3'-0" height from the "H" you are left with a CMU height that is not modular for 8" high block. In other words it dosent work out for full 8"x8"x16" units as indicated in the legend on page #969.

Does the state want to use a 4" high unit instead to achieve the height for all the sound walls? If so where in the vertical placement will this 4" unit be placed? Or does the state want to increase the "H" value to 14'-4" and 16'-4" so that FULL units can be used for this project? If the state chooses the 2nd option, then the engineers estimate for the SW quanity totals will have to be revised since this is a final pay item. Thank you.

Inquiry #12: Ref. sheet 1649 of 1931 (Buena Vista Street Underpass); At Detail 5 "Deck Plate Transverse Field Splice Detail", the note at the field weld symbol states "remove backing". The weld backing for that portion of the weld at the girder flange is the girder flange itself and thus can not be removed. Please confirm the weld backing BETWEEN the girder flanges must be removed.
Inquiry submitted 08/22/2012

Response #1:Yes, only the weld backing between the girder flanges must be removed.
Response posted 08/22/2012




Inquiry #13: Ref. Painting of Structural Steel; Standard Specification Section 55 "Steel Structures", paragraph 55-3.13 requires all structural steel to be cleaned and painted. As there is no Clean and Paint Structural Steel special provision on this project and the structural steel for the railroad bridges is all weathering steel, we question whether or not painting is required. Please clarify.
Inquiry submitted 08/22/2012

Response #1:Painting is not required.
Response posted 08/22/2012




Inquiry #14: Per the Inquiry #2 Response. Can you please state if the walls that were noted are to ONLY use full 8"x8"x16" units or maybe half blocks (4") be used? And where do we place these half blocks, at the bottom or top of the wall.

The original question was asked because the contract documents DO NOT provide adequate information and are incorrect.

Response #1:The Contractor needs to:
1. Have their track superintendent coordinate with SCRRA before the cutover.

Inquiry #17: Please reference the plan note on sheet 1428, “CUT AND THROW LIMITS. TRACKWORK BY SCRRA. MATERIALS FURNISHED UNDER THIS CONTRACT. SEE NOTE 6.”

Please define the term “CUT AND THROW”. Does SCRRA intend to shift the existing track to meet the alignment of the Shoofly or does SCRRA expect new trackwork materials (rail, ties, etc) for the Cut and Throw limits of construction?
Please define what “trackwork” materials are required to be furnished.

Inquiry submitted 08/24/2012

Response #1:The "cut and throw" operation, also called "lining over" the track will be utilized to provide the track required for the track alignment shifts. In that process the track is realigned partially by disconnecting and shifting existing track elements and partially by constructing new elements. Please refer to the contract documents for the limits. The contractor shall provide new rail, ties and fasteners and rail joining materials for the new sections of track.

Inquiry #37: Sheets 183 and 184, Drainage Details DD-1 and DD-2 Type 60 W Mod Concrete Barrier shows an underdrain that is called out as "no plastic pipe". There are no specifications in the 2006 and 2010 SSP or the Special Provisions of this contract.

Response posted 09/06/2012




Inquiry #44: Per the bidders questions responses #2 and #14 I don't believe the State understands the questions. There's an error in the engineers estimate quantites for the CMU total quantities for the walls listed. If you build the walls per plan the CMU height will be 11'-0" or 13'-0" of total masonry height, which is not modular to 8" high units. The first response said nothing will change unless an addendum is issued, bid per plan. And the second response stated to only use 8x8x16 CMU. But heights of 11'-0" and 13'-0" are not possible to build with full 8x8x16 units. If you use full height units, then the CMU height will be 11'-4" & 13'-4" and the current engineers estimate does not reflect those CMU heights.

In other words the state wants the walls to only use full units, but do not want to issue an addendum to change the CMU heights to 11'-4" and 13'-4" so that modular full units can be used. And the state dosent want 4" high units. Right now those heights and the engineers estimate are based on non-modular 11'-0" & 13'-0" CMU heights. This requires that the engineers estimate be revised. Its like saying "Were only paying for the shorter height, but you must supply the higher height, using only full blocks".

Please review and advise.

Inquiry #48: Regarding CalTrans' response to Inquiry #5, Section 10-1.112 "Miscellaneous Metal (Austin Vault)" covers only the 230 LB of miscellaneous metal in Bid Item 273 "Miscellaneous Metal (Austin Vault)" We still believe a special provision section should be issued to cover the 582,960 LB of Miscellaneous Metal (Bridge) at Bid Item 270 as there is undoubtedly a significant amount of miscellaneous metal in that bid item that is not specified in Standard Specification Setion 75-1.03 "Miscellaneous Bridge Metal".

Inquiry #57: Reference Addendum 1, revised Bid Schedule. CALTRANS has not identified any of the changes made to the Bid Schedule and has always done so by tagging each change by left hand denotation. In addition, Bid Items Descriptions have been deleted and within that same Bid Item number replaced with different descriptions/scope of work. This has created extremely difficult changes to manage/address within our established estimate and does not seem to follow CalTrans processes and procedures. Please re-issue the Bid Schedule addressing deleted items and descriptions of work by strike (or denoting as ‘BLANK’) through and placing added items and descriptions of work at the end of the bid item schedule as has been done on past CalTrans projects and in accordance with established CALTRANS policies and procedures.

Inquiry #58: Section 10-1.45 Lightweight Fill EPS Geofoam Block of the NSSP needs to be clarified. The material specification actually points to several different densities simultaneously. EPS29 (1.8 pcf) is called out by name. The density of 1.5 pcf min refers to EPS24. The compressive strength @ 1% deformation requirement can only be met with EPS39 (2.4 pcf). There price difference between these 3 possibilities is hundreds of thousands of dollars for this volume. In order to provide a level playing field amongst the suppliers and bidders, the actual density required must be quantified precisely. Feel free to contact me directly for recommendations to clarify the specification based on the performance requirements of the project.
