Inquiry #11: Please clarify the difference between Bid Item 56 (structure ex for retaining wall) and Bid Item 57 (structure ex retaining wall(Type A)). Since the “excavation and backfill” detail on plan sheet 3 of 39 shows all retaining wall ex to be classified as “structure excavation (Type A)” why are there additional retaining wall excavation items?

Since all the abutments are included in Bid Item 54, what is included in Bid item 53 (Structure Ex Bridge) quantities (401 cy)?

Also, please clarify why the structure ex limits as hashed on sheet 3 of 39 do not go all the way to the original ground surface. The structure ex quantities are shown to extend to the bottom of seal course concrete but the quantities in the bid proposal do not seem to account for this.

Inquiry #12: Due to the number of unanswered bidders inquiries for this project, would Caltrans postpone the bid opening date in order to provide time for bidders to fully evaluate the responses once they are posted?

Inquiry #13: The notice to bidders mandates that you cannot include more than 300 working days into the bid. Because of the staging it takes two seasons of work in the stream zone (June 15-Oct 15) to complete the work. If the Attorney General approves the contract immediately and the 55 day waiting period passes the contractor could be required to start work in early 2014. Since work will not complete until after the second season (2015) stream zone window, if contract time is charged continuously it will far exceed the allowable 300 days.

Will CALTRANS allow work to be suspended immediately at project start at contractor request until schedule critical work starts related to the first season (2014)window? Also will CALTRANS suspend time even if non critical work is being completed between the first and second stream zone windows?

Response #1:Submitted for consideration.
Response posted 10/11/2013


Response #2:Typically working days will not be charged if the contractor cannot work on the controlling operation. Not being able to work on the controlling operation could be for a variety of reason including but not limited to weather conditions and permit restrictions. A formalized winter suspension just recognizes ahead of time restrictions already in the contract. If contractual restrictions on this contract prevent the contractor from completing the controlling operation as shown on an approved CPM, working days should not be charged.

Inquiry #15: Bid Item #109, Seal Course Concrete has a bid quantity of 412CY. Using the formation shown on drawing sheet #82 it appears that there is to be 3'-0" of Seal Course Concrete beneath all retaining wall footings. Based on that information, and adding the volumne from the 4' deep section below the abutments, we come up with more than twice the 412CY on the bid form.

Do all the retaining walls have the Seal Course Concrete beneath their footings? Is the 412CY correct?

Inquiry #28: Addendum 3 added a Utility Relocation Table to section 5-1.36D of the specifications. It shows that the existing overhead utility lines on the south side of bridge will not be moved until 9/29/14. It appears this will push stage 1 construction into 2015. Is this correct?

AT&T and Comcast utilities will follow up PG&E and finish their utility relocation before 09/29/14, but the AT&T and Comcast utilities will not be conflicted with the stage 1 bridge construction. Therefore, the construction will still start in 2014.
