MEMORANDUM
TO: Board of Supervisors
FROM: Scott De Leon, Public Works Director
DATE: October 24, 2017
SUBJECT: Approval of Change Order No. 1 for Harbin Springs Road at Harbin Creek Bridge Replacement Project, Federal Project No. BRLO-5914(106), Bid No. 17-04
EXECUTIVE SUMMARY: Attached for the Board's review and approval is Contract Change Order (CCO) 1 for the subject project.
