Addendum 1-Bid 6445 Questions And Answers with Images.pdf

This Addendum 1 document is a Questions and Answers supplement to Bid PWG 126-OPERA-6445 issued by the San Bernardino County Department of Public Works for traffic roll-up signs. The addendum, dated July 16, 2026, addresses bidder inquiries regarding the specifications for standard and custom legend roll-up construction signs, particularly regarding Velcro overlay requirements for directional messaging such as "RIGHT/LEFT" and "AHEAD." A bidder submitted a question requesting the complete list of required legends and text for custom signs, including specifications for which lettering applies to each sign size and type, noting that the original solicitation documents did not contain sufficient detail on these specifications. The addendum references attached specification sheets and visual examples, including photographs of changeable-message roll-up signs demonstrating the Velcro mesh overlay application method that allows for use of fewer 48-inch mesh signs with interchangeable overlays.

The document includes referenced image attachments (numbered 1000006224 through 1000006228) and a file labeled "Changeable-Message-roll-up-signs-2" that provide visual specifications for the sign configurations. The contact information for the Department of Public Works main office is listed as 825 East Third Street, San Bernardino, California 92415-0835, with Noel Castillo, P.E. identified as Director. This addendum serves as clarification material for bidders preparing responses to the traffic roll-up signs solicitation prior to the July 30, 2026 bid submission deadline.
