Inquiry #8: There are several locations along the project that have off-ramps and on-ramps that require the shoulder to be reconstructed as indicated Per Structal Section Note 9 on Sheet X-1. The replacement of the structural sections for the shoulder are more than a foot deep and the traffic handling plans do not indicate temporary barrier at these locations. The shoulders are only a few feet wide with a significant drop off at the edge of the shoulders, making it difficult to construct a temporary tapered edge as required by Caltrans Standards when the ramp is in use. We believe temporary barrier is required at these locations to reconstruct the shoulders, could Caltrans please revisit these areas to determine if temporary barrier is necessary?

Inquiry #25: Per summary sheet Q-6, curb ramp reconstruction calls for 111cy of Aggregate Base to be placed underneath the new curb ramps. However, there is no roadway excavation shown for this same qty. Where is the excavation under the curb ramps paid for? We believe it should be under Roadway Excavation, but there is no qty for this scope in the Summary of Quantities for Earthwork.

There is an qty for Remove Base and Surfacing, but this appears to be for the HMA patching in front of the curb ramps and not for the excavation underneath. Please add and item or adjust the Roadway Excavation qty to account for this scope.

Inquiry #28: For Crack Treatment, Addendum 3 shows a qty of 3 Lane Miles spread out across the project in the summary of quantities page 289 (Q-1). Where are the 3 lane miles that are slated for crack treatment? The length of road in the areas shown on the summary of qty's is 17.80 Lane Miles.

It is important for the contractor to know where the 3 lane miles are because it will significantly impact production since the crack treatment needs to be done in the same shift as the cold plane and RHMA placement. We need to know how many lane miles of paving will be effected, so we know when crack treatment will be needed.

Please provide provide actual stationing of the lane miles needing crack treatment.

Inquiry #36: Regarding Bid Item 119.
The PDQ sheets only call out a few arrows and few sections of line to be MMA. Page 97 (PDF page 111) of the NTB and Special Provisions requires a BPN of 60 for the MMA. You can’t get 60 BPN with spray applied MMA. The arrows and lines currently called out as MMA would have to be the squeegee applied version of MMA. Are these few arrows and lines really supposed to be MMA?

Additionally, the PDQ sheets list the green bike markings, 10’x10’ bike boxes, and crosswalks as thermoplastic. However, the detail on PDD1 calls these items out as MMA.
Should the green bike lane markings, 10’x10’ bike boxes and continental crosswalks be added to bid item 119?

Inquiry #37: Regarding Bidders Inquiry #36. The response "..bid per current contract documents" needs further clarification.
The contract documents contradict themselves.
Sheet PDD-1 requires MMA for the continental crosswalk markings and for green bike lane markings.
All the PDQ sheets list these items under the Thermoplastic Pavement Marking column, NOT in the MMA column.
If sheet PDD-1 is correct, the quantity for Bid Item 119 should be closer to 28,000SF.
Bid Item 119 is currently only 670 SF
Clarify which markings are to be MMA and what the true Bid Item Quantity is for item 119.
