Additional Questions
Q1. Spec section 4000-22 (Sheet 220 of 572), states that bid item #16 - Crushed Misc.
Base is to be for the staging area CMB, but the take -off quantity for the staging area
fell short of the engineer's quantity for BI#16. Please confirm that the additional
quantity of CMB is to be for the walkway adjacent to the sides of the bridge as shown
on Plan sheet 8 of 73? (Construction Note 54).
A. The CMB was provided to the staging area surfacing along with the CVWD
ramps from the street to the top of the channel per note 54. The additional
quantity is for the ramp areas as noted on sheet 8 @ approximately station
23+50, right and left along with the details shown on sheet 3 for the two
details for the CVWD driveway accesses.
The Contractor is hereby notified; Addendum No. 1 must be acknowledged and initialed
as stipulated under the instructions to Bidders and submitted as part of the Bid. Failure
to do so shall result in the City designating said bid as "Non -Responsive."
