Inquiry submitted 11/15/2023
Response #1:The inquiry has been received and submitted for consideration.
Response posted 11/15/2023
Response #2:X-1 and X-2 show the cold plane and pave limits as the saw cut line minimum 1' from the face of the barrier. The proposed sections for the cold plane and pave extend to the saw cut line. This is consistent with the Layouts. The pay quantities include this.
Response posted 11/20/2023

Inquiry #16: As an example of other locations, what is the reason for approximately 8-feet of cold plane & overlay offset from face of existing median barrier (existing barrier not shown to be removed) in both directions between Sta. 335 and 350?
Inquiry submitted 11/28/2023
Response #1:The inquiry has been received and submitted for consideration.
Response posted 11/28/2023
Response #2:The approximately 8' offset of the cold plane and overlay from the face of the median barrier at this location ("NE1" St 335 to 350) is to avoid existing drainage and concrete pavement. Other locations with an offset throughout the project limits are also to avoid damaging or paving over drainage, concrete pavement and other features.
Response posted 11/28/2023
Inquiry #17: The 6-55 hour closures allow for 1 lane in each direction, most of the work to be done during the closures will need 2 lanes in each direction. The removal and replacement of the barrier will be unsafe to move in a single lane. Can you change the 6 - 55 closures to allow for the #1 and 2 lanes in each direction to be closed?
Inquiry submitted 11/28/2023
Response #1:The inquiry has been received and submitted for consideration.
Response posted 11/28/2023
Response #2:We cannot allow the closure of the #2 lane in either direction during the 55-hour closures. Note that you have two lanes total to remove the existing barrier and erect the new barrier, not one. Please bid appropriately.

Inquiry #22: Per Existing Section 5 on Sheet X-1, there is an existing section of 1.2' of AC. After the removal of the existing barrier, there will still be existing asphalt under the proposed barrier. Note 4 on Sheet X-1 requires the placement of 0.33' minimum HMA under new barrier construction unless otherwise noted on the plans. Standard Plans for Concrete Barrier Type 60MGC in particular appear to show that the barrier is to be construction on either pavement or well compacted base. Please clarify if new HMA (0.33' Min.) will be required under the new barrier if the existing AC is still in place as detailed by Existing Section 5.
Inquiry submitted 11/28/2023
Response #1:The inquiry has been received and submitted for consideration.
Response posted 11/28/2023
Response #2:A minimum of 0.33' of HMA under the barrier must be replaced with new HMA to account for damage to the pavement below during the concrete barrier removal process, and unknown condition of the existing HMA below the barrier. As shown, the toe elevation of the barrier should remain the same as existing.
Response posted 11/29/2023
Inquiry #23: In reference to note 4 on plan X-1 (sheet 2), please provide a roadway excavation bid item to remove the 4" of existing AC pavement for the proposed 4" HMA base under the new median barrier.

Response #1:The inquiry has been received and submitted for consideration.
Response posted 11/30/2023
Response #2:Only HMA that is damaged needs to be replaced to at least 0.33', to meet requirements per the standard plans and specifications for the new barrier installation. Please ignore note 4 on X-1. No roadway excavation pay item is needed.

Response posted 11/30/2023

Inquiry #27: Bid Item 14, and sheet SCQ-1 call out a quantity of 120 ea for the Lateral Shift of the Moveable Barrier. There is no information on how Caltrans arrived at this quantity.
Please confirm that payment for a lateral shift is 1 ea to move the barrier out at the start of the work shift, and 1 ea to move back the barrier at the end of shift. Also confirm that a Lateral Shift is per each direction -- Northbound and Southbound. Summary - if the moveable barrier is laterally shifted in the NB and SB direction, and shifted back -- this is 4 ea Lateral Shifts for the work day.
Inquiry submitted 11/30/2023
Response #1:The inquiry has been received and submitted for consideration.
Response posted 11/30/2023
Response #2:Correct that each lateral shift is per direction and that each working period (including 55-hour closures and nightly closures for this project) would have four total lateral shifts utilized if both directions are closed. This item will be paid appropriately per the contractor's actual work schedule.

Inquiry #28: On 11/30/23 this response was posted for bidder inquiry #23
"Response #2: Only HMA that is damaged needs to be replaced to at least 0.33', to meet requirements per the standard plans and specifications for the new barrier installation. Please ignore note 4 on X-1. No roadway excavation pay item is needed. Response posted 11/30/2023"
We find the Response #2 to inquiry 23 to be contradictory. In the first sentence, we are directed to replace .33’ to meet the requirements of the standard plans & specification and in the second sentence, we are told to ignore note 4 on X-1. However, note 4 states: “Place .33’ minimum HMA (Type A) under the new concrete barriers, unless otherwise noted on the plans.” The two sentences in the response seem to conflict with each other.
Please consider issuing an addendum with a revised X-1 sheet showing/detailing clear direction to all the contractors the HMA needs under the new barriers.
Inquiry submitted 12/01/2023
Response #1:The inquiry has been received and submitted for consideration.
