Inquiry #11: On Q-2 under the Existing Surface Treatment chart, everything is summarized as if the work is expected to be done within these station limits under tis contract. If you add the quantities of Cold Plane in the two columns to the Cold Plane quantity on the Roadway Quantities chart on Q-1, it comes up to almost the exact quantity of cold planing for the project. However, this is shown on X-1 as Existing Surface Treatment and is labeled as same on Q-2. Does Caltrans want the Contractor to remove the existing rumble strips by grinding 0.25' & plug paving back with AC? Also, Note 2 of the Stage Construction plans talks about cold planing and placing HMA, which is not what is called for based on the details shown on X1 & X-2. If so, the details and the summary sheets appear to be very confusing. What is the Cold Planing Item for if the details on X-1 &X-2 indicate "Existing surface treatment"?

The item is for cold planing AC pavement to depths up to 0.25' and 0.50' as indicated on plans. See X-1, X-2 and Q-2 for more information.
Response posted 09/23/2013




Inquiry #12: You reponse to inquiry #11 part B is incorrect. The label at the top of the table on the Roadway Quantities sheet clearly states "Existing Surface Treatment". The layout drawings have a left hash legend also calling this "Existing Surface Treatment".
There is no detail on the X Drawings that calls for cold planing anywhere except on X-2 where it shows to cold plane the full width of the roadway @ Sta. "B"117+00 to 123+80. This amounts to a total of 1,813 SY, which shows up on your chart. There is no other typical section on the plans that calls for cold planing. Please look at your plans before you respond.

Inquiry #15: The remove rumble strip table on sheet Q-2 indicates 27 sqyd of remove rumble strip on the project (we have not found this shown on the plans). 27 sqyd at 1.17' wide as per the detail on sheet C-11 works out to approx 208 lf of remove rumble strip. The stationing provided in the remove rumble strip table is a total of 8150 lf. Is it correct that there is only 208 lf of remove rumble strip on the project? Additionally, 27 sqyd at 0.50 ft deep works out to approx 9 ton of HMA not 54 ton. Is the information in the remove rumble strip table correct? Could plans be provided showing the remove rumble strip locations and limits so bidders could quantify the work?

Please issue an addendum that corrects the specifications to show that ONLY Hot Rolled Sheet piles, that are manufactured in th USA, will be allowed on this project, and tht AZ 26 sheet piles, are NOT acceptable, and do not meet the specifications.

Inquiry #38: Specification page limits single lane road closures to 0.33 miles. There is probably 15,000 tons of finish asphalt overlay required for this project. To achieve a smooth finished project without numerous joints and bumps the paving contractor needs to pull the full length of the roadway. Since cross traffic is not an issue on these two road sections I need to assume that we will be allowed to extend the 1 lane closure thru the entire length of the project, assuming locations 'A' and 'B' will be paved at seperate times.
