The Central Unified School District (“District”) hereby gives Notice that Public Contract Code section 20111.6 requires all general contractors holding either an A or B license, and mechanical, engineering, and plumbing first-tier subcontractors holding C-4, C-7, C-10, C-16, C-20, C-34, C- 36, C-38, C-42, C-43, and/or C-46 licenses (collectively "Contractors") to be prequalified with a public entity if a public works project involves a projected expenditure of $1 million or more and is funded completely or in part with State facility bond funds.


It is mandatory that all licensed contractors who intend to submit bids fully complete the pre-qualification questionnaire, provide all materials requested therein, and be approved by the District to be on the final prequalified bidders list. If two or more business entities submit a bid on a project as a joint venture, or expect to submit a bid as part of a joint venture, each entity within the joint venture must be separately qualified to bid.


The District has contracted with Colbi Technologies dba Quality Bidders Inc. to provide a web-based process for prequalification.  Prequalification application packages are accessible by visiting Quality Bidders website at A link is also available on the District’s website on the Facilities Planning Webpage. This prequalification packet includes a questionnaire and financial statement, to be verified under oath. The District will use the information and documentation required by the packet to prequalify general contractors and mechanical, electrical and plumbing subcontractors in accordance with applicable law. 

Pre-qualification approval will remain valid for one (1) calendar year from the date of notice of qualification, except that the District reserves the right during that calendar year to adjust, increase, limit, suspend or rescind the pre-qualification ratings of any contractor based on subsequently learned information and after giving notice of the proposed action to the contractor and an opportunity for a hearing consistent with the hearing procedures described below for appealing a pre-qualification determination.



The District is seeking submission of prequalification packages specifically related to the construction of Justin Garza High School Ballfields Increment #2, a New Elementary school and a Visual and Performing Arts Theater. The delivery method for these projects is a multi-prime. Contractors shall submit prequalification packages, along with all required supporting documentation between March 10, 2023 and April 28, 2023 (“Submission Deadline”), so that they may be notified of prequalification status well in advance of the bid process. Applications submitted prior to March 10, 2023 or after April 28, 2023 will not be considered. Prior to the Submission Deadline, any contractor may withdraw its prequalification packet or submit a new prequalification packet in place of a previously and timely submitted prequalification packet. Owner reserves the right to modify the time and/or date stated above.

The prequalification packages shall be completed electronically using the Quality Bidders platform.  They may accessed by visiting  A link is also available on the District’s website on the Facilities Planning Webpage.


The questionnaire answers and financial statements included in the prequalification packages submitted by contractors are not public records and are not open to public inspection. All such information provided will be kept confidential to the extent permitted by law, although the contents may be disclosed to third parties for the purpose of verification, investigation of substantial allegations, and in the process of any subsequent proceedings. State law requires that the names of contractors applying for prequalification status shall be public records subject to disclosure, and the first page of the questionnaire will be used for that purpose.


Evaluation by the District and Prequalification

The District will evaluate the information provided and issue each submitting contractor a rating of “Prequalified”, “Not Prequalified” or “Qualified Up to [DOLLAR VALUE]”. The District’s decision will be based on the information provided, references, and such additional outside information as the District in its discretion deems reasonable and necessary to obtain. The District may, but is not obligated to, investigate the truth of any statements or information provided by a prospective bidder in response hereto

The District reserves the right to amend the prequalification packet at any time. The District also reserves the right to waive minor irregularities and omissions in the information contained in the prequalification questionnaire submitted, to make all final determinations, and to determine at any time that the pre-qualification procedures will not be applied to a future public works project of the District. Additionally, a determination by the District that a contractor is prequalified does not amount to a final determination that such contractor is responsible or responsive for purposes of bid evaluation. The District may, in accordance with applicable law reject a prequalified contractor’s bid, and the District may additionally reject all bids if it determines such action is in the best interest of the District.


A contractor who has timely submitted a completed application form, and who receives a rating of “Not Prequalified” or “Qualified Up to [DOLLAR VALUE]” from the District may appeal that determination. There is no appeal from a finding that a contractor is not prequalified because of a late application or a failure to submit required information. A contractor may appeal the District’s decision with respect to its request for prequalification, by giving written notice to the District no later than five (5) business days after the contractor’s receipt of notice of its qualification status. Notice shall be sent to the contact persons at the email addresses and physical address listed above. It is the responsibility of the Contractor to confirm receipt by the District. Unless a contractor files a timely appeal, the contractor waives any and all rights to challenge the qualification decision of the District, whether by administrative process, judicial process or any other legal process or proceeding.

If the contractor gives the required notice of appeal and requests a hearing, the hearing shall be conducted so that it is concluded no later than ten (10) business days after the District’s receipt of the contractor’s Notice of Appeal.  The hearing so provided shall be an informal process conducted by a panel of one or more persons to whom the District’s governing board or designee has responsibility to hear such appeals (the “Appeals Panel”).  At or prior to the hearing, the contractor will be advised of the basis for the District’s pre-qualification determination. The contractor will be given the opportunity to present information and present reasons in opposition to the pre-qualification determination.  At the conclusion of the hearing or no later than three (3) business days after completion of the hearing, the Appeals Panel will render its decision.  The date for submission and opening of bids for a specific project and any subsequent contract award will not be delayed or postponed to allow for completion of an appeal process


Questions concerning this this notice shall be submitted in writing to, and received by, the Contact Person listed above prior to 3:00pm on April 27, 2023. Contractor to verify receipt by District.
