REPORT TO COUNCIL
SUBJECT
Title
Award of Bid No. PW18-17 for Mary-Carson Tank No. 2 Refurbishment, Determination of Bid Non-responsiveness, and Finding of California Environmental Quality Act categorical exemption

REPORT IN BRIEF
Approval is requested to award a construction contract in the amount of $948,320 for the base bid and $94,500 for the Additive Bid Alternate for a contract total of $1,042,820 to West Coast Industrial Coatings, Inc. of Hemet for the Mary-Carson Tank No. 2 Refurbishment project.
