Inquiry #12: Plan sheet 399 and 400 show Temporary Fiber Roll, Temporary Hydraulic Mulch (bonded fiber matrix) and Temporary Silt Fence have large amounts of contingency for season one and season two……Since the contingency has a possibility of not being performed most likely these items will go into adjustment? Conceivable options are; 1) Can the State please separate the actual bid item from the contingency thus having two items for each? 2) The other option is to eliminate the contingency from the project thus allowing us to bid the actual designed work. This will eliminate the possibility of a probable protest as there are contractors out there that will unbalance their bid to take advantage of the State…

This is problematic – please address….

Inquiry #18: In regards to question 10 concerning import borrow. The geotech report indicates that Caltrans would have the right of way to accomodate the need for import by digging onsite detention basins. However the answer to question 10 indicates the State has not acquired the right of way to use onsite material and the contractor should bid as indicated in the Special Provisions. If there are contractors that have more intimate knowledge of the use of onsite material it could create an unfair bidding atmosphere. Please assure the contractors of Caltrans' clear intentions regarding import material available from onstite basins.

Inquiry #29: Under the Clearing and Grubbing in the project special provisions it states that Vegetation shall be cleared and grubbed only within the excavation and embankment slope lines. If this is the case then its my understanding that all the area between the old and new alignments with trees and vines etc. would remain in place. Is this correct?
Also, after driving the proposed project site we find that it is very hard, if not impossible to figure out where and how many trees and vines etc. are to be removed. There are very few stakes in the ground and the ones that are are just here and their. Could you please provide demo/removel sheets with this info or stake the project limits for clearing so this item of work can be bid accurately?
