Submit new inquiry for this projectInquiry #1: Why is the State requiring a bonded wearing course with an integrated spray paver for this project? It is not typical to require a bonded wearing course for a .2' thick RHMA-G structural section. What is the benefit of applying a polymer modified asphaltic emulsion under a .2' lift of 3/4" RHMA-G with an integrated spray paver vs. applying the emulsion with a distributor truck (Boot Truck) in front of a conventional paver?
The cost of using an integrated spray paver is much higher due to slower production and lack of availability.

Inquiry #12: It is understood that Caltrans includes all work codes associated with the bid items on this contract to identify DBE firms certified in the CUCP that could perform work on this project to help establish the 22% DBE goal. When Caltrans calculated the 22% DBE Goal for this project what work codes were identified as contributing to $4,202,000 value of potential DBE participation? What methodologies / calculations were employed to take into account the current capacity of those potential DBE’s to handle this much work in this geographic area?

Response #1:(BI#12)-Your inquiry has been received and is being reviewed.
Response posted 08/16/2023
Response #2:(BI#12)-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.
