Although "public projects" or "public works projects", as defined in California Public Contract Code Section 22002, are exempt from the City's Centralized Purchasing System their provision has an impact on effectively implementing the City's Capital Improvement and in some cases Capital Expenditure Programs. The procedures for the solicitation of contractors or other individuals qualified to complete "public projects" or "public works projects" shall be pursuant to California Public Contract Code Sections 20160—20174. In addition to these procedures, the City recognizes the ability to initiate "design—build" public projects or public works projects pursuant to California Government Code Section 5956 through 5956.10 and California Public Contract Code Sections 22160 et seq., and 20194.

A. Purchase Amounts of $5,000.00 or Less. Purchases of supplies, equipment, materials and services with a price of $5,000.00 or less may be made through a using department of the City without City Manager or City Council approval and does not require the following of either the open market procedure or formal bidding procedure as established in this chapter provided that there is an unencumbered appropriation in the fund account against which the purchase is to be charged and that department head approval by the using department is obtained. Purchases made under the $5,000.00 limit shall be referred to as "over the counter purchases."
B. Professional Services—Consulting Services. The selection of vendors or bidders to provide professional services—consulting services shall be done in accordance with procedures established in the City of Atwater Purchasing Manual and shall be predicated upon the qualifications based selections process, Section 3.04.300.
C. Sole Source Purchases. Commodities and services which may be obtained only from one bidder or vendor are exempt from the centralized purchasing process. Sole source purchases may include proprietary items sold directly from the manufacturer, items that have only one distributor authorized to sell in a geographic area or a certain product that has been proven to be the only product that is acceptable. All sole source purchases shall be supported by written documentation signed by the appropriate department head and forwarded to the Purchasing Division. Final determination that an item is a valid sole source purchase shall be made by the Purchasing Officer, or his/her designee.
D. Public Projects or Public Works Projects. Pursuant to Sections 20160—20174 of the California Public Contract Code, contracts for "public projects" or "public works projects" which have an estimated value greater than $5,000.00 shall be contracted for and let to the lowest responsible bidder by the procedures set forth in State Law. The Public Contract Code defines a public project as (a) a project for the erection, improvement, painting, or repair of public buildings and works, (b) work in or about streams, bays, waterfronts, embankments, or other work for protection against overflow, (c) street or sewer work except maintenance or repair, and (d) furnishing supplies or materials for any such project, including maintenance or repair of streets or sewers.

As an alternative to initiating a public project or public works project through the bid procedures described by State Law the City may initiate a "design - build," process through the selection of a qualified consultant, pursuant to California Government Code Sections 5956 through 5956.10 10 and California Public Contract Code Sections 22160 et seq., and 20194. Under the "design - build," process a public works project or public project may be exempt from bidding requirements and other requirements provided that the selected consultant was chosen on the basis of competence and professional qualifications and that the work to be completed is to be paid through fee producing infrastructure. To this end, should the City of Atwater initiate a "design - build" project, the process for obtaining professional services is outlined in Section 3.04.300 and shall be adhered to.
E. Other Exemptions. The City's purchasing system may be dispensed of when other State or Federal statutes or regulations prescribe a separate specific purchasing process such as in the case of public works projects and public projects, Federal and State funded grant activities, or other such instances which specify that as a condition of contract award or funding that a specific purchasing process other than the City's is to be followed.
(Ord. CS 987, § 2, 12-11-2017)
3.04.120 - Deviations from centralized purchasing.¶
Minor modifications or deviations from the City's Centralized Purchasing System may be necessary to carry out the functions of the City or to comply with State, Federal, or other intergovernmental regulations. These situations shall be determined on a case by case basis and shall require the approval by the Purchasing Officer, or his/her designee, prior to initiating a purchase. Modifications or deviations should only be considered in situations where it will allow the City's Centralized Purchasing System to be modified or deviated from slightly in such a manner that it would permit the carrying out of functions of the City when acting under a State, Federal, or other intergovernmental grant or in the carrying out of State, Federal, or other intergovernmental funded activities in which the City is involved.

A. Preferred Method. The use of purchase orders to effectuate the purchases of all supplies, equipment, materials and services shall be made by purchase order when possible and may be paid for using a credit or debit card issued to the City of Atwater when procedures as outlined in the Purchasing Manual or other adopted procedures.
B. Open Purchase Orders. An open purchase order is an agreement whereby the City contracts with a vendor or bidder to provide equipment or supplies on an as-needed and often over-the-counter basis. Open purchase orders provide a mechanism whereby items which are uneconomical to stock may be purchased in a manner that allows operations timely access to necessary materials. Open purchase orders shall not be used to purchase services, capital assets or items maintained in stock. The Purchasing Division shall request confirmation of open purchase orders annually, before the beginning of the fiscal year. Requests for open purchase orders may also be submitted to the Purchasing Division on an as-needed basis. The Purchasing Division shall review open purchase order requests based upon criteria developed in the City of Atwater Purchasing Manual. Once an open purchase order is issued to a bidder or vendor, any authorized City employee may contact the bidder or vendor directly to place orders per the terms and conditions specified in the open purchase order unless otherwise stated in the contract to execute the open purchase order.
C. Contract Purchase Orders. Contract purchase orders are the preferred method of purchasing repetitive-use items or services which may be common to several departments or within one department or provide generalized services to the City which shall be needed on an ongoing basis. Establishing contract purchase orders provides a means of obtaining volume pricing based upon the combined needs of all departments, reduces the administrative costs associated with seeking redundant competitive bids and processing a purchase order each time an order is placed, and allows departments to order as needed, reducing the requirement to maintain large inventories of stock. If a contract purchase order exists, departments shall order all of their requirements from the successful vendor. No other source shall be used without prior approval of the Purchasing Officer, or his/her designee. Using departments shall submit, in writing to the Purchasing Division, any performance problem encountered immediately following the occurrence so that corrective action may be taken. Contract purchase orders are annual and may include option for renewal for specific products, product types, or services at agreed upon prices or pricing structure and for a specified period of time.
(Ord. CS 987, § 2, 12-11-2017)
3.04.150 - Cooperative purchases.¶
The Purchasing Division and any using department may participate in purchases and contracts established by other political jurisdictions, provided the cooperative agreement is established following a competitive bid process similar to the City's Formal Contract Procedure. The City Manager may authorize the award of cooperative purchase agreements up to $25,000.00. City Council approval is required for the award of any cooperative purchase of $25,001.00 or more. This process is often called "piggy backing."

3.04.270 - Local business preference program.¶
In evaluating competitive bids or quotes to determine the lowest responsible vendor/bidder any local vendor/bidder shall be granted a preference in an amount equal to five percent off of their bid or quote if a non-local bidder/vendor is initially determined to be the lowest responsible bidder/vendor of a good or services being solicited. If after deduction of the five percent preference from a local vendor/bidder's bid or quote, it is equal to or less than the lowest bid or quote submitted by the non-local bidder or vendor, the purchase award shall be awarded to the local vendor/bidder. In the event that a non-local bidder/vendor and a local bidder/vendor have the same bid or quote and it is the lowest responsible bid or quote the five percent preference need not be applied the local business shall be selected to receive the purchase award. For purposes of this section, a qualified local vendor/bidder is defined as any individual, partnership, or corporation which regularly maintains a place of business and an inventory of merchandise for sale within the incorporated City limits of the City of Atwater and has a valid business license issued by the City of Atwater during when the bid or quote is provided. All contractors who submit bids or proposals to construct or provide work on any City Public Works Project, or for any other Public Works construction, or improvement, on City property, and who are seeking a local business preference, must make a good-faith effort to hire qualified individuals who are residents of the City of Atwater or Merced County in sufficient numbers so that no less than 50 percent of the contractor's total construction work force, including subcontractor work force, measured in labor work hours, is comprised of Atwater residents. This same requirement applies to all subcontractors. A non-local bidder or vendor shall be all others which may do business with the City of Atwater. The local business preference may not apply and may be dispensed with when prohibited by State or Federal Statutes, or regulations requiring that a bid or quote be awarded to the lowest responsible bidder or vendor, or as otherwise exempted from local preferences. The local business preference shall not apply to purchases made through the over the counter process since items less than $5,000.00 are exempt from the purchasing system, however a using department making a purchase under the over the counter process shall make every attempt possible to purchase through local businesses. Under no circumstances shall the local business preference granted in a single bid or quote exceed $5,000.00. The local business preference will not apply when bids or quotes are done with other public agencies through cooperative purchases.
(Ord. CS 987, § 2, 12-11-2017)
3.04.280 - Inspection and testing.¶

3.04.300 - Qualifications based selection.¶
Pursuant to California Government Code Sections 4525—4529.5 various professional services are prescribed by State law to be selected by local agencies based upon demonstrated competence and on professional qualifications, cost of the services shall be secondary to the qualifications to perform the required professional or consulting services. The City finds that in addition to the types of services specified in the California Government Code Sections 4525—4529.5 other professional or consulting services should also be awarded based on competence and professional qualifications. These may include, but are not limited to, professional or consulting services by a person or firm engaged in a profession based on a generally recognized special knowledge or skill, including, but not limited to, the professions of accountant, attorney, artist, architect, landscape architect, construction manager, engineer, environmental consultant, dentist, physician, training or educational consultant, or land surveyor, and whose services are considered distinct and unique to such a degree that bidding of such services would not be feasible. In order to ensure compliance with State law and that selection is done in an unbiased manner promoting the merits of qualifications and competence the City shall follow procedures as included in the Purchasing Manual. Additionally, the criteria to be used in making the selection shall be:
A. The ability, capacity, and skill of the bidder to perform the contract;
B. Whether the vendor has the facilities to perform the contract promptly, or within the time specified, without delay or interference;
C. The character, integrity, reputation, judgment, experience, and efficiency of the vendor;
D. The vendor's record of performance of previous contracts;
E. The previous and existing compliance by the vendor with laws and ordinances relating to the contract;
