Inquiry #14: Special Provisions Section 12-4.04C states that "A Pedestrian facility closure on the same side of the highway is limited to no more than 1 block.
When working on one side of the highway, the pedestrian facility on opposite side of the highway within the same block must be open"
Concurrent pedestrian facility closures on the same side of the highway must be speced at least 2 blocks apart".
This restriction does not allow for the completion within 10 calendar days for each stage 1A, 1B, 2A, and 2B, as per the requirement on
section 8-1.09 Disincentive for late completion" It does not provide enough time for the contractor to demo, grade, base and pour all the minor concrete, while being restricted to a closure on no more than 1 block.
Would Caltrans reconsider extending the Calendar day duration allowed per stage, or eliminate section 12-4.04C of the Special Provisions for this project?

Inquiry #15: Cross sections on Sheet X-11 of the project plans indicate the following:

STA 347+53 to STA 376+04 shows an existing structural section of 0.2' of AC over 0.85' CTB on the shoulders.
The plans call for a new shoulder structural section of 0.15' RHMA-G over 0.45' HMA Type A, which will require breaking through the CTB section.

STA 376+04 to STA 385+52 shows an existing structural section of 0.2' of AC over 0.85' CTB on the shoulders.
Plans require to cold plane 0.3', and pave back 0.15' RHMA-G over 0.2' HMA Type A, which will also require breaking through the CTB section.

How will Caltrans pay for the removal of the CTB, and the additional embankment needed to replace the void as the contractor will also need to recompact subgrade, and all of this will increase the depth of the shoulder section?

Inquiry submitted 06/05/2025

Response #1:Your inquiry has been submitted for review.
Response posted 06/05/2025

Response #2:Sta 347+53 to 376+04, the removal of CTB is covered under “Roadway Excavation” Section 19 in the Standard Specifications.

Sta 376+04 to 385+52, CTB removal for shoulder section is covered under Cold Plane Asphalt Concrete (CPAC) activity. During CPAC, subgrade should not be disturbed by the contractor. If subgrade is disturbed by the contractor, re-compaction spec will apply, and contractor is responsible for this work without any extra payment.

As far as depth, Cross section sheet X-11 shows 0.30ft of CPAC and placing back 0.35ft of pavement (0.20ft HMA and 0.15ft RHMA). No increase in depth.
