Inquiry #7: Bid item 73(F) Furnish Sign Structure (Lightweight) is called out to be used however the sign sheets do not have design sheets for these lightweight sign structures. The sign panels for these structures are shown on SD-1 however a structure design is required with details showing the span, post height, post type, span design, mast tube sizes etc... This is a final pay item so it must have design drawings for each structure.

In addition to the above the lightweight sign structure sheets were deleted from the 2015 standard plan book and lightweight design drawings have not been put back into the 2015 book. The 2015 book only has sheets S48, S49 & S50 but these sheets are not complete and currently only apply for Extinguishable Message Sign Structures (Lightweight) which these structures are not EMS's. The 2010 Standard Plan book started at S41 to S50 but were deleted so standard plan design sheets also need to be provided for these structures.

Inquiry #13: Section 14-6.03A states that vegetation removal within the Main Flood Canal and Westside Canal shall be removed by hand. These areas are heavily overgrown with vegetation and hand removal is impractical since all material must be removed from the channel/canal. Since equipment is allowed in the channel/canal for construction of the bridge and box culvert can mechanical vegetation removal be utilized?

Response #2:
The Caltrans biologist has requested that the initial vegetation removal within the Main Flood Canal (Kern River) must be done by hand.

Inquiry #16: Retaining wall #1 on RMP 3 line at STA 946+35 to 947+00 is in Stage 2C. Per the stage construction plans 2C will be constructed under the ramp closure chart J1. The ramp closure chart J1 only allows for a 30 HR complete closure. The 30 HR closure window is not enough time to construct both the new roadway and retaining wall. A retaining wall of this size will take several weeks to construct not including the cure time of roughly 7-14 days before backfill can start. Please provide a new traffic chart for an extended ramp 3 closure.
