contractorIn June 2005, the Rio School District Board of Education authorized the District’s participation in the California Uniform Public Construction Contract Program. As a condition of bidding, and in accordance with the provisions of section 22034 of the California Uniform Public Construction Cost Accounting Act (CUPCCAA) and Rio School District Board Policy 3311, prospective contractors (bidders) on projects with an estimated cost of between $15,000 and $175,000.00 are required to complete and submit the application below:

Prospective CUPPCAA Applicants - Materials

Rio School District - Prequalification for Construction Projects

In order to comply with Assembly Bill (AB) 1565 that went into effect January 1, 2014, we now require all prime contractors and M/E/P Subcontractors to be prequalified prior to submitting bids if the contract is valued at $1 million or more or if the project utilizes a Lease-Leaseback delivery method.

Public Contract Code 20111.5 enables districts to require prime contractors to be prequalified prior to
accepting bids.

Public Contract Code 20111.6 requires the district to do so for certain projects. This applies to prime
contractors and MEP sub-contractors with the following licenses:

This applies to the following license numbers:

  • General Contractors (A and B)
  • Mechanical, Electrical, and Plumbing subcontractors (C-4, C-7, C-10, C-16, C-20, C-34, C-36, C-38, C-42, C-43, and C-46)

The Rio School District has contracted with Colbi Technologies (aka QualityBidders) to provide a web-based process for prequalification. QualityBidders is a web-based online application that is fast, simple, safe and easy to use.

Submission Timeline
Contractors shall submit prequalification packages, along with all required supporting documentation between March and June 13, 2022 (“Submission Deadline”), so that they may be notified of prequalification status well in advance of the bid process. Applications submitted after June 13, 2022 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.

To get started, please visit, and follow the instructions for creating an account if you do not have one already.  After creating an account, you will be able to complete the prequalification application and submit it on-line.  


All questions in the questionnaire must be answered. If a question is not applicable, then indicate a response of “N/A”. Each questionnaire must be signed under penalty of perjury in the manner designated at the end of the form by an individual who has the legal authority to bind the contractor on whose behalf that person is signing. If any information provided by a prospective bidder becomes inaccurate, the prospective bidder must immediately notify the District and provide updated accurate information in writing, under penalty of perjury. Each prospective bidder shall have a duly authorized owner, officer or principal complete the questionnaire and verify the truth of the information provided therein and in the financial statement. 

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 of Prequalification package by the District
The District will evaluate the information provided and provide a response of qualified or not qualified through the Quality Bidder website. 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.

The District must receive applications at least ten (10) business days prior to the scheduled bid opening on any advertised project in order for the candidate to qualify for that project. Prequalification approval will remain valid for one (1) calendar year from the date of notice of qualification except as noted in the prequalification documents. 

Please contact Wael Saleh, Assistant Superintendent, Chief Business Official with any questions at or (805) 485-3111.  You may also contact with any questions about the use of the Quality Bidders web-based tool.

Thank you for your interest in prequalifying and working with the Rio School District.

We look forward to a successful partnership.
