Purchasing Director's Message

Welcome to San Joaquin Delta College Purchasing Department.  The primary responsibility for the procurement of all supplies, equipment and services as well as Public Works Bidding process for San Joaquin Delta College has been delegated by the District’s Board of Trustees to a centralized Purchasing Department.

All procedures are designed to conform to the laws of the State of California and the policies and regulations established by the Board of Trustees to assure that purchases are property authorized and result in quality goods or services being delivered to the designated locations at the appropriate time, in the right quantity, and at the lower possible cost.

The purchasing staff is expected to conduct themselves in a courteous, ethical and professional manner; to maintain good relations with faculty, staff, and vendors. Grant all competitive vendors equal consideration; to regard each transaction on its’ own merits; and to foster and promote fair, ethical and legal trade practices.

The District encourages the participation of local and/or small businesses, including, but not limited to, minority, women, disabled, veteran or disabled veteran owned businesses, as suppliers, prime contractors or subcontractors/suppliers for the prime contractor, as permitted by Public Contract Code Section 2002 and per the District’s Administrative Procedure 6330.

We hope that the Vendors will use these procedures as a guideline in dealing with the District.  We appreciate their interest and service to the District and hope that all associations with us will be mutually pleasant and beneficial.

Should you have any questions, please feel free to contact me at (209) 954-5065 or via e-mail at

Maria G. Bernardino
Director of Purchasing

Vendor Requirements The following information is being provided to current and prospective vendors to remind them of certain requirements that must be met when providing material or services to the college.

Service Providers: If you are a service provider, please be aware that prior to the award of the project, you will be expected to submit your Worker’s Compensation and Liability Insurance Certificate for a minimum of $1,000,000 showing San Joaquin Delta College as the “Additional Insured” and not as a “Certificate Holder.” The Contract and Purchase Order will not be issued until the above requirements are met.
  2. Prevailing Wage: The Contractor shall observe and comply with all requirements set forth in the Labor Code, Sections 1770 et Set., Governing Prevailing Wage Rates and Employment of Apprentices, Labor code, Section 1777.5 and Section 1811-1815 Governing Hours of Work. Current prevailing wage rates can be obtained from the Department of Labor Relations @
  3. Video Tape Suppliers: In order to comply with the Office of Civil Rights, we are now requesting closed-captioned versions of all video recordings we order, if available. In the case where the closed-captioned version is not available, the regular version videotape will be acceptable.

Appointments: Are they necessary? Appointments are necessary because the purchasing personnel can not put their time absolutely and indiscriminately at the disposal of all sales representatives; however, they still have an obligation of courtesy and should give manufacturers, vendors, or distributor’s reasonable consideration.

Making an appointment guarantees:
  • An audience with the appropriate purchasing personnel
  • Maximum utilization of buyer’s and seller’s time
  • An opportunity to set up the meeting to include other personnel
  • Adequate time for preparation or compilation of topics to be discussed with the sales representative
  • The opportunity to enhance public relations

Know who is authorized to commit the district’s funds In each school district the Governing Board of Trustees shall designate District Officials who shall be authorized to sign purchase orders and other purchase or contractual obligations of the District. San Joaquin Delta College Board of Trustees has designated the Vice President of Business Services to sign purchase orders. The Superintendent is the designated official to sign contractual obligations of the district. San Joaquin Delta College is not responsible for purchases made other than through the Purchasing Department The departments or individuals making such purchases may be held liable for payment to the vendor. As a vendor, you would be protecting yourself and your company if you made the following inquiries:
  • What signature or signatures are valid when doing business with San Joaquin Delta College?
  • Does San Joaquin Delta College issue a verbal Purchase Order number?
  • Is it necessary to verify the Purchase Order number given verbally?
  • When an individual is picking up materials on a verbal purchase order number it is a good idea to ask for identification, proof of employment with the district, etc.
  • Open or Yearly Purchase Orders must specify the name of the individuals authorized to pick up the order.
  • Unsolicited phone calls or sales calls directly to department(s) are not permitted. Vendors are required to contact the Purchasing Department, who is the college authorized purchasing agent for any purchasing related questions.

Bypassing Purchasing Department - The Risk Occasionally a sales representative will bypass the Purchasing Department and make a sale directly to a person or department. There are definite RISKS in doing business with San Joaquin Delta College in this matter – below are a few examples:
  1. San Joaquin Delta College may not be liable for goods furnished without an authorized purchase order and the requestor placing the order may be personally liable for the purchase.
  2. Payment MAY NOT be made if the proper procedure has not been followed.
    • Requisition processed so department can be charged
    • Purchase Order issued so funds can be encumbered
    • Funds set aside so payment can be guaranteed
    • Proof of delivery so invoice can be approved for payment
  3. Vendor will be faced with these two possibilities:
    • At best – payment will be delayed
    • Worst yet – Vendor may not be able to get paid, since purchase was not authorized
  4. Vendors should work directly with the Purchasing Department to ensure payment
