Inquiry #1: Looking for clarification on line item 57 the Pre Construction Surveys as per section 73-3.01C. Does the preconstruction survey need to be preformed while the contractors concrete forms are in place or can it be preformed prior to construction beginning.
Inquiry submitted 07/16/2014

Response #1: Submitted for consideration.
Response posted 07/17/2014


Response #2: The preconstruction survey could be done prior to construction beginning, but the contractor must be able to verify that forms and site constraints will allow the design dimensioning and slope requirements to be achieved. Note that Section 73-3.01C of the Special Provisions requires the surveys to be submitted within 2 business days of performing the surveys.

Inquiry #2: Most of the typical sections on plan sheets X-1 to X-3 appear to show the 0.10’ cold plane and 0.10’ hma-sp (type A) from ETW to ETW only, such as PM 25.70 to PM 29.00 on sheet X-1. However, a couple of the typical sections appear to show it additionally on the inside and/or outside shoulder, such as PM 23.16 to PM 25.70 on sheet X-1. Additionally, the quantities of cold plane and hma-sp on Q-1 appear to include the inside and outside shoulders for all of Rt 99. Could you please confirm the limits of the 0.10’ cold plane and 0.10’ hma-sp (type A) for the project? Are the typical sections correct?

Inquiry #3: Plans sheets C-6 to C-8 and C-10 to C-15 identify all concrete under the bridges as concrete barrier (transition). However the Infill wall/concrete barrier transition plans sheets identify the portions between the columns as concrete infill walls. Will the portion of concrete barrier between the columns be paid as concrete barrier (transition) or structural concrete (retaining wall)?

Inquiry submitted 07/24/2014

Response #1: Submitted for consideration.
Response posted 07/24/2014


Response #2: Refer to Standard Specifications Section 9-1.03 “PAYMENT SCOPE”: “Payment for a bid item includes payment for work in sections referenced by the section set forth by that bid item.” Specifications for excavation and backfill are included in Section 83-2.02D “Concrete Barrier.” Therefore, this work is included in the payment for the concrete barrier (transition) bid item.

Inquiry #5: Some of the ramps shown on plan sheets C-20 to C-34 show remove concrete gutter/dike or remove pcc gutter/dike. Others show remove ac curb or remove ac dike. What is refered to as concrete gutter or pcc gutter appears to be an existing e curb without an ac dike. Is this correct? If so, there is no bid item to pay for this removal as it is not remove asphalt concrete dike. If the e curb is removed it will also need to be replaced with some material, which is not shown on the plans. Please clarify.

Inquiry #9: Sheet 79 shows the concrete barrier transitions at Moshier Creek bridge, Bear Creek bridge, & Live Oak Canal bridge being paid under both the Minor Concrete (Minor Structure) and the Concrete Barrier (Type 60R Mod) items.

Inquiry #20: In regards to the Special Provision continuously being written for Section 37-6: High Friction Surface Treatment: if Caltrans is content with limiting the opportunity to perform this application to only one or two bidders, then it is understandable to continue restricting competitive bidding by imposing the unreasonable and unnecessary requirements under Subsection 37-6.04B – Mixing and Application Methods.

However, striking “Application 2 (Mechanical mixing and aggregate broadcast) must not be used on areas with a slope of greater than 2.5 percent in any direction.” from 37-6.04B(1); and the portion of 37-6.04B(2) requiring that both the resin binder and high friction aggregate “be applied by the same automated continuous application vehicle”, “equipped with a built-in data management unit which is capable of producing real time data flow showing… 3. the volume of aggregate applied throughout the application width” would open the field and introduce a more competitive bidding environment to include experienced high friction surface treatment contractors who employ equally effective alternative means and methods of performing the application.

We request that these modifications that accomplish the safety goal of HFST at a more competitive price, without compromising the quality of the finished product, be made to the structure of the standard High Friction Surface Treatment section of the Special Provisions.

Inquiry #21: Reference Detail C-2 for “Typical RHMA-SP-G Under Structure”: This detail, in combination with Special Provision 15-2.02B(3)(a) requiring the ground surface to be paved back in the same shift, will in essence force contractors to utilize a cold planning machine during almost every RHMA-G paving shift – significantly driving up the cost to perform the work. Furthermore, the areas under the structure have not been excluded from the 0.1’ cold plane and 0.1’ HMA-SP in your typical sections or summary of quantities. Please either clarify that the intent is to initially cold plane 0.3’ and replace with a section of 0.2’ RHMA-SP-G / 0.1’ HMA-SP, or allow traffic to ride on the milled surface in these areas for an extended period of time.
