Q2) What is the existing structural section for existing Santa Fe Grade Road and existing Wolfsen Road where we are to remove base & surfacing?

A2) No coring was done for the roadway sections in question, and as-built drawings are unavailable. Therefore, quantities of "Remove Base and Surfacing" will be determined from measurements taken at the site during removal. 17Nov10

Q3) Can additional cross-sections/plans be made available to accurately quantify structural cut/fill at Salt Slough BR, San Joaquin River BR, and San Joaquin River Overflow BR?

A3)No cut/fill cross sections are available at those locations. Refer to the contours shown on the Foundation Plan sheets for the referenced bridges (Sheets 65, 78, and 91 of the plans). 17Nov10

Q4) For Item No.41, Erosion Control (Hydroseed) (SQFT), on page nos. 95 and 96, what are the application rates for Fiber, Commercial Fertilizer and Tackifier for the first and third application of Erosion Control (Hydroseed)?

Q7) What is the note Driveways (58) on Sheet 47 of 110 (Q-1). Does it mean that there are 58 driveways that need to be paved? We need to know the approx locations of these 58 driveways. Sheet 13 & 48 (C-3 & Q-2)show that 8 of these driveways require 870 SY of milling. We need to know how Caltrans arrived at 610 Tons quantity for these driveways. Please clarify.

A7) Yes, the note 'Driveways (58),' in "Roadway Quantities" on Summary of Quantities Q-1 (Sheet 47 of the plans), indicates that there are 58 private driveways to be paved along Route 165. Since the project is not surveyed (stationed) except at the structures, there was no meaningful, reproducible way to represent these driveways on the plans. The quantity of HMA (610 tons) was determined from the average size of the driveways (approximately 10 tons/driveway). Note that the cold planing locations in the tables on Construction Details C-3 (Sheet 13 of the plans) and Summary of Quantities Q-2 (Sheet 48 of the plans) refer to mainline Route 165 and 6th Avenue, not the driveways. 29Apr11
