Inquiry #1: This project is currently scheduled to bid on 12/20/18, the week before the holiday break. We are hearing that many DBE & Non-DBE subs & suppliers will not be working the week of the 17th or the 24th. We intend to close our offices between 12/21/18 and 1/1/19. We are certain that we can provide Caltrans with a more competitive bid, including more comprehensive DBE participation, if the bid date is extended to the week of 1/7/19.

Inquiry #7: Please refer to plan sheets L-1 thru L-4. The legend on plan sheet L-1 for this area describes the new road section as 0.15' Rubber-AC/Paving Mat/0.1' AC. It does not mention AC milling or leveling course. New road section #5 on plan sheet X-1 does mention this. Which is correct?

The quantities on plan sheet Q-2 imply that there will be an average of a 0.1' AC leveling course required for all the road sections on this project. Is this a guess? How will the length. width and depth of the leveling course areas be determined in the field? Are we allowed to mill the asphalt and leave a 0.25' drop-off at the end of shift?

Inquiry #9: There appears to be a conflict between plan sheets TH-1 thru TH-4 "Traffic Handling Plans" and specification page 16 Chart #K1. Chart #K1 allows the contractor to limit thru traffic to one lane (12' width) from 11 PM to 6 AM. Plan sheets TH-1 thru TH-4 require the contractor to leave a 22' width lane for traffic. Why is there a 10' difference between the specifications and the plans?

Response #2:The "traffic area" may vary from 12' to 22' in conformance with the lane requirement chart K-1 , the 22 foot traffic area is for when 2 lanes are required, 12 foot when only 1 lane is required.

Response #2:Per the Revised Standard Specifications(see below), cold planning existing pavement and placement of HMA are to be done in the same work shift, thereby rendering it impractical to lower and raise the utility manholes/handholes.


2015 Revised Standard Specifications read:
Add to the end of section 39-3.04A:
Schedule cold planing activities such that the pavement is cold planed, the HMA is placed, and the area is opened to traffic during the same work shift.


In addition, for existing drainage facilities, section 71-5.04 says that if no bid item is included for adjustment of these facilities, payment is included in the pavement items.

Refer to section 9-1.03 of the Standard Specifications
