Response #2:1) Existing dikes are on asphalt.
2) Yes, the existing asphalt should be removed and replaced.
3) Though existing dikes are on asphalt, the specified replacement dikes may be wider at the base than the existing, therefore causing a need to excavate a wider area to accommodate the new dike as well as placement new asphalt in this wider area.

Inquiry #12: Caltrans Standard Specifications 2015, Section 6-1.05 Specific Brand or Trade Name and Substitution states "reference to a specific brand or trade name establishes a quality standard and is not intended to limit competition.

Inquiry #14: Regarding the MGS work & locations. With no layout sheets in the plans and only the quantity summary's to go off of it appears there are multiple guardrail runs combined in general areas.
