Methods of Procurement


Micro-Purchases are purchases which do not exceed $5,000 for MSE or $10,000 for Services. Micro-Purchases may be made without obtaining competitive quotes if the price to be paid is fair and reasonable. (California Public Contract Code Section 20251.)

Small Purchases or Simplified Acquisitions

Small Purchases or Simplified Acquisitions are purchases where the estimated expenditure is between $5,000 and $75,000 for MSE or less than $250,000 for Services.

To the extent practicable, such a method shall involve obtaining a minimum of three quotations, either written or oral, that permit prices and other terms to be compared.

Formal Solicitations – Invitation for Bids (IFB) and Request for Proposals (RFP)

Generally, an IFB will be used for the procurement of MSE when the expenditure exceeds $75,000, but RTD has the option to use a best-value approach in circumstances where it is determined to be in the best interest of RTD.

Generally, an RFP will be used for the procurement of Services when the expenditure exceeds $250,000, but RTD may elect to use an IFB process when it is determined to be appropriate for the procurement and in the best interest of RTD.

Specialized State and federal laws will apply to the procurement of architectural and engineering (A&E) services as defined by applicable laws and regulations, regardless of the estimated expenditure.

Public Works

RTD has opted into the California Uniform Public Construction Cost Accounting Act (CUPCCAA). Pursuant to CUPCCAA, projects for the construction, reconstruction, erection, alteration, renovation, improvement, demolition, repair work, painting, or repainting of RTD-owned, leased, or operated facilities (“Public Projects” or “public works”) will be procured as follows and in compliance with RTD’s informal bidding ordinance (Ordinance No. 002).

  1. Public Projects which do not to exceed $60,000 (or the current threshold set forth in Public Contract Code Section 22032(a), whichever is higher) may be let by negotiated contract, purchase order, or performed by RTD’s employees by force account. Generally, RTD will not use federal funding for Public Projects valued at $60,000 or less. However, in the event it will use federal funding for such a Public Project, RTD will use the informal bidding procedures set forth below.
  2. When the expenditure for the Public Project is greater than $60,000 but less than $200,000 (or the current thresholds set forth in Public Contract Code Section 22032(b), whichever is higher), the contract will be let by informal procedures set forth in Ordinance No. 002, as it may be amended from time to time.
  3. Public Projects of more than $200,000 (or the current threshold set forth in Public Contract Code Section 22032(c), whichever is higher) will be let by formal bidding procedures set forth in CUPCCAA. Alternative methods of procurement, such as a design-build approach, may be utilized if authorized by state law and in full compliance with all applicable requirements.

Disadvantaged Business Enterprise (DBE) and Small Business Enterprise (SBE)

RTD is committed to a DBE Program for DBE participation in RTD contracting opportunities in accordance with 49 Code of Federal Regulations (CFR) part 26, as may be amended. It is the policy of RTD to ensure nondiscrimination on the basis of race, color, sex, or national origin in the award and administration of U.S. Department of Transportation assisted and RTD contracts. It is the intention of RTD to create a level playing field on which DBE’s can compete fairly for contracts and subcontracts relating to RTD’s public works, MSE, and Services.

RTD is committed to ensuring equal opportunity for all vendors interested in our projects. We strongly encourage contractors, subcontractors, joint ventures, and Disadvantaged Business Enterprises (DBE) to bid/propose on relevant projects and contracts.

RTD also encourages the participation of certified Small Business Enterprises (SBE) in all of its procurement activities. At all times RTD promotes small business participation by establishing and maintaining a plan that will assist small business competition and eliminate any obstacles that may prevent their participation as prime contractors or as subcontractors.


RTD will pay approved invoices within thirty (30) days after receipt. Contractor must pay subcontractors for satisfactory performance of any of the services/work performed by subcontractors within ten (10) days of receipt of payment by RTD for such services/work. Contractor must return retainage payments to each subcontractor within ten (10) days after the subcontractor’s work is satisfactorily completed.


All invoices must be submitted to:


Address: San Joaquin RTD
