Inquiry #4: Per the Special Provisions 2-1.08 there was a mandatory pre-bid meeting that was held on 9/11. Due to the fact that the mandatory pre-bid meeting was not advertised like it typically is on all Caltrans bids it was not attend by some prime and subcontractors. In all other previous instances Caltrans lists "This project has a mandatory pre-bid meeting" in BOLD font on the All Projects Currently Advertised web page, however for this project it was not advertised that way (reference currently advertised projects that display this requirement 02-1H1104, 03-3F5104, 08-1C38U4, 12-0K0214). Additionally, the Notice to Bidders (Page 1) of the SP's did not specify there was a mandatory pre-bid meeting in this overall contract summary/requirement page which is where this requirement is specified on all other contracts. The only way to see this requirement would be to do a complete specification review multiple weeks before the bid, which is not standard practice of contractors and subcontractors on a job of this size

By not specifying the mandatory pre-bid requirement in the fashion that Caltrans typically does, and is doing on all other current advertisements, has caused some prime and subcontractors to be excluded from bidding the project by missing the pre-bid meeting. Please consider issuing an addendum and holding another mandatory pre-bid meeting in order to allow additional contractors and subcontractors to bid the project and obtain the most competitive pricing possible on this project.
