Please clarify the basis for award for this project. Is the project awarded on the base bid total or the base bid plus alternates? (RFC 2307-2 submitted 7/12/2023)

See response to RFC 2307-4. Response date: 07/19/2023
Where is bid item 12, Replace Asphalt Concrete Pavement, located? Will the County provide a summary of the locations including widths and lengths and locations? Is the HMA for this item incidental to the item or paid under bid item 15, Hot Mix Asphalt? (RFC 2307-7 submitted 7/12/2023)
See response to RFC 2307-4. Response date: 07/19/2023
At locations with a HMA section of 0.30' does the County require the HMA be placed in one lift or two lifts? If the County requires two lifts, does the County want 3/4" or 1/2" HMA? If the County requires 1/2" HMA please add a bid item for HMA with 1/2" grading. (RFC 2307-8 submitted 7/12/2023)
