Specifications include, but are not limited to:. Catalog numbers, brand names, or manufacturer’s product or reference numbers used in the item specifications are intended to be descriptive, not restrictive. These references, as well as “approved brands” listed, are intended to identify and indicate the type of product being sought, and establish the level of quality desired. If any conflict exists in the item specifications between the product descriptions and any brand names or model or reference numbers used, the product descriptions will override the brand names or model number references. In most cases, bids on brands of equivalent nature and quality will be considered, provided they are regularly produced products from a reputable manufacturer. However, in some cases, the Program may find it advantageous to standardize equipment and/or supplies by manufacturer in order to achieve efficiencies in procurement, repair, and operation, to match existing stock, or to satisfy other requirements. In these cases, preference will be given to the specific products identified as “approved brands,” especially if all other evaluation factors are deemed to be equal. For this reason, where specific brands or models are identified, it is preferable for the Bidder to bid on the exact item specified, in addition to an alternate brand or model where desired. All bids must identify the manufacturer, brand, model, etc. of the article being offered. For bids on “or equal/equivalent” items other than any “approved brand” specified, the Bidder must supply a complete description and sufficient data for the Program to properly analyze the product being bid. Samples may be requested for items other than “approved brands.” If the Bidder fails to identify the manufacturer, brand, model, etc. for any item being bid on, the Program will assume the Bidder is bidding on the exact brand and model identified in the specification, and if awarded, the Bidder will be required to supply the exact brand names, models, etc. as specified. Substitutions will not be allowed. The apparent silence of the specifications as to any detail or the apparent omission from any specification of a detailed description concerning any point shall be regarded as meaning that only the best commercial practices shall prevail. All interpretations of the specifications shall be made on the basis of this statement. If the Bidder discovers or suspects an error in the item specifications in this Bid Invitation, please note it as part of the Bidder’s bid response. The Program will attempt to correct errors for future Bid Invitations.
