Effective July 1, 2014, Public Contract Code § 4104 has been amended to now require that all contractors disclose the Contractors State License Board license numbers of their listed subcontractors on public works project bids. It is important that all contractors biding public works projects take note and include this newly required information in order to avoid potential bid protests and payment withholding issues. Under the new statute, inadvertent errors in license number listings must be corrected within 24 hours of bid submission in order to avoid a bid protest.
