Inquiry #24: Hello:
On page 1297 of the project drawings, SW1-3 "Sound Wall Details", Note #1 at the top, calls out for the CMU block and color to match exiting sound walls nearby. Going NB on the 55 from Willow Creek On-Ramp to the 5 SB Connector, the existing wall sound wall in the area is the following:

- 8x6x16 slumpstone (tan color) (25%) - (field)
- 8x8x16 4Score-Split-Face-2sides (dark tan color) (2-courses on top of wall)
Detail "A" of the plan sheet calls out all the units to be 8x8x16, but slumpstone is only available in 8x6x16 size. Please clarify if we are to match the slumpstone as I have listed for SW#514 and RW#506.

Inquiry #29: Hello:
In regards to our previous question, INQUIRY #25, if the state is looking for (2) courses of 4ScoredSplitface-2Sides to top off the CMU sound wall on RW#506, while also having raked cuts on both the bottom and top of wall, the aesthetics of 4Score CMU is not going to look right.
There will be small slices and slivers of 4score cut as the slope changes. Which will impact the look of the 4score aesthetics, and also possibly the designer's intention. We recommend building the CMU wall to follow the grade/top of retaining wall. And then making up the differences at expansions and or electroliers with 2"+ cuts that will never be seen. You would have a more uniform looking sound wall with out the need of cuts and slivers of 4score at the top.
If needed please reach out to us to discuss and/or explain. Thank you.

Per this table there are 343,474 c.y. of roadway excavation, 87,062 c.y. of embankment and 89,237 c.y. of imported borrow. If the embankment is subtracted from the roadway excavation leaves a surplus of 256,412 c.y. of excavated material. Why is there a pay item for import borrow when there is a surplus of roadway excavation?

Inquiry #38: Special Provisions Section 19-2.03B states " Dispose of surplus material. Ensure enough material is available to complete the embankments before disposing of it." Special Provisions Section 19-7.02C states "Imported borrow placed within 4 feet of the finished grade must have an R-value of at least 40 and a Plasticity Index less than 12 percent." Based on topography and new structural sections, this project is an export project. However, based on Caltrans bid quantities, it appears that the Contractor is expected to excavate a minimum of 4' from finished grade in paved areas (even where structural sections are less) in order to place imported borrow material with the specified R-Value. Overexcavation is specifically shown in project plans at retaining wall footings, box culverts and Lane Channel, however no overexcavation is specified in the roadway section. Please confirm that it is Caltrans’ intent to overexcavate beneath the structural section in order to place R-Value 40 material within 4’ of finished grade.

Inquiry #48: Bid Item 304 “Thermoplastic Traffic Stripe (Enhanced Wet Night Visibility)†and Bid Item 313 “Traffic Stripe (Warranty)†are both comprised of multiple striping details, including varying widths (6†– 8â€) and various skip patterns (36-12, 17-7, 12-3, etc). Pricing for these different striping details varies greatly and bid items 304 and 313 are not final pay. In order to provide competitive pricing and the best value to Caltrans, Contractors should price each item at their respective value to generate a composite price, however we are concerned that if the quantity is increased for the most expensive striping detail but paid for at a composite unit price, we will not be fairly compensated. Please confirm method of compensation for additional striping. In addition, please consider adding bid items for the different striping details in order to fairly compensate Contractors for increases in quantities.
