Response #2:The Office of Civil Rights (OCR) only uses work codes that have sufficient DBE firms in the District where the project is located.
OCR has additional adjustment factors for each District based on the number of DBEs that will work in that District.
For example, District 8 has more DBE firms than the more remote Districts such as Districts 5 and 9 so the adjustment factor is different.
Work codes used toward the DBE Goal for this project include:

C1200 C1920 C3901 C5620 C8609
C1201 C1930 C4010 C6200 C8722
C1532 C1980 C5100 C6650 C8730

Inquiry #20: Approximately 70% of the length of this project is an overlay of the existing asphalt roadway with a new PCCP section that is over 1’ higher than the existing roadway.  The staging plans require construction of the detour road in Stage 1.  This detour road becomes the finish surface of the permanent inside shoulder.  Because the asphalt and aggregate base sections in the detour roadway are significantly higher than the adjacent existing roadway in Stage 1, several issues arise with the current design: 1) Without the future Stage 2/3 concrete to pave against in Stage 1, the edge compaction and grade control of the detour (future inside shoulder) paving is not possible. Will Caltrans consider paying for cement treatment, a concrete “retaining curb”, or a thickened edge of asphalt to prevent deterioration of this edge?
