When Caltrans calculated the 22% DBE Goal for this project what work codes were identified as contributing to $16.5 million value of potential DBE participation?

Response #1:(BI#3)-Your inquiry has been received and is being reviewed.
Response posted 08/16/2023
Response #2:(BI#3)-A determination was made on what work may potentially be subbed out to DBEs. A review of all the bid items on the contract was performed and compared to DBE firms who are certified in the CUCP to perform those work items and indicated an interest to work in the district that this project is in. Nonetheless, bidders are required to select portions of work to be performed by DBEs in order to increase the likelihood that the DBE goals will be achieved. This includes, where appropriate, breaking out contract work items into economically feasible units (for example, smaller tasks or quantities), beyond those listed via these Work Codes, to facilitate DBE participation, even when the prime contractor might otherwise prefer to perform these work items with its own forces.
Please refer to the contract documents, special provisions, and Standard Specifications 2-1.12 for the DBE requirements on this contract. You may find 49 CFR Appendix A to Part 26 I. DBE Regulation on Guidance Concerning Good Faith Effort helpful.

Inquiry #50: Reference Sheet D-7 and DQ-12 (Traction Sandtrap No. 6). Sheet D-7 calls out 8" APUD for drainage unit "c". On Sheet DQ-12 there is no LF noted under column for 8" APUD and only LF is noted under column for 2" Plastic Pipe (Sch 40) Supply Line. This same issue occurs for Traction Sandtrap No. 8, No. 15, No. 17, No. 20 and No. 21 (8" APUD noted on "D" sheets but not "DQ" sheet). Please clarify intent and update item quantities as needed.
Additionally, Sheet DQ-12 does not call out 2" Plastic Pipe (Sch 40) Supply Line for the majority of the Traction Sandtraps. Per Sheet DD-16, it appears every drainage inlet gets at least a short section of 2" pipe. Please clarify intent and update item quantities as needed.

Inquiry #84: Reference Concrete Invert Paving (Bid Item #130 / Sheet DD-2). For at least some of the existing culverts called out to receive invert paving, they appear to have existing invert paving installed in them now. It is not clear whether all culverts have this condition. Special Provision Section 71-3.04C states “Before paving the invert, remove all coatings, corrosion and other surface material until only base steel is exposed by sandblasting the portion to be paved”. Sheet DD-2 (Invert Paving Detail) Note #2 states that the interior surface shall be cleaned "with high-pressure water jet and/or wet sandblasting".
If existing culvert cleaning method specified (high-pressure water jet and/or wet sandblasting) is not sufficient to remove all existing surface material, it is assumed it would be change order work to properly clean/prep surfaces. Please confirm.
Which culverts (drainage system numbers) are we to assume have existing invert paving in them now that is required to be removed/cleaned?

X-1 has shown the depth of grinding to be .06' and the depth of inlay to be .06'
C-4 shows the grinding to be .06' and the inlay to be .15' via Section C-C and Detail A
Is the intention for Caltrans to have a grinding done to create an edge for inlay with an average depth of .15' due to the "wheel rutting"?
Otherwise, the summary of quantities Q-1 is overstated by more than 50%
The total is also incorrect as the 5 items total 19,224 CF, not 18,064 CF

Inquiry #105: Special Provisions requires a Contractor-Supplied Biologist monitor during "clear water diversion installation and removal". No other monitoring requirement is listed.

Does the 40 DAY estimate account for the additional CDFW monitoring requirements?

Response #2:(BI#105)-The 1600 agreement only applies to the 5 locations called out in the project description, not the entire project. Some monitoring in the permitted areas may not be necessary if no water is present at the time of work. For example clear water diversion or dewatering.
Measure 2.15 can be completed by the construction personnel as applicable. The designated biologist is not solely responsible for that work.
The Department believes 40 days is an acceptable amount of time to complete this work.

Inquiry #107: Addendum 2 revised Special Provision Section 12-4.02C(3)(g) Freeway Lane Closure charts. Note 2 states, "Vehicles may only access the active work zone when the adjacent lane is closed during approved lane closure hours." This will require all clear and grub, import, roadway excavation, aggregate base, asphalt, JPCP and polyester work at night with lane closures. Is this the intent of the revised/added note? Roadway excavation and import embankment work at night on a steep rocky slope creates more of an unsafe working condition than working during the day. Will Caltrans consider revising lane closure chart G1 to allow lane closures Monday-Thursday from 1200 to 1800 (similar to Chart G2 off peak season)?

Inquiry #111: Lane closure chart No. G1 and G2, provided in Addendum 2, only allows vehicles to access the work zone when the adjacent lane is closed with a lane closure. This will allow for only night work during the Peak Season. Most of the work will need to be completed during the Peak Season as Earthwork commenced, must be completed by October 15th (Per Plan Sheet SC-1). This change by the State eliminates day work during the most productive part of the year. The change also eliminates the ability to work multiple shifts in a working day (Night and Day Shifts). Will Caltrans consider revising the minimum and maximum working days due to this change to the lane closure charts?

DBE Truckers, Suppliers and Subcontractors will now have to work at night in a remote location. Many can and will find day work at a project much closer to home.

Inquiry #114: Would Caltrans entertain the possibility of substituting MMA with alternative materials such as Thermoplastic or Two-Component Paint Stripe? Caltrans has encountered widespread failures of recessed MMA, particularly on state highways exposed to snowy conditions. District 3, 8, and 4 have all recognized that MMA is not a suitable product, concurring that it is highly brittle and prone to easy fracturing, leading to delamination from the pavement surface.
Furthermore, it's noteworthy that project numbers 03-1G4204, 03-3H4504, and 08-0K1224 serve as instances where considerations were made for product substitution, transitioning from MMA to epoxy. Project 09-213404 notably permitted the use of EWNV thermoplastic instead of MMA prior to the bidding process.
