Verify the quotation against the specified model. If there is a genuine need to broaden the selection range, the authorized party must first process a document amendment according to standard project procedures.<\/li>\n\n\n
Accept alternative quotations that indicate the actual supplied model, and verify key requirements as specified. It will only be included in the qualified bid comparison after meeting the requirements and passing the evaluation or approval stipulated in the document.<\/li>\n\n\n
Seek written clarification within the prescribed Q&A period regarding whether substitutions are allowed, under what conditions they will be evaluated, and when supporting evidence must be submitted. Until a clear answer is received, list the alternative quotation separately as “pending confirmation.”<\/li>\n<\/ul>\n\n\n\n
Take FAR 52.211-6 (Brand Name or Equal)<\/strong> in US Federal Acquisition as an example. Tenders adopting this clause require the “equal” item to meet the salient physical, functional, or performance characteristics specified in the solicitation. The bidder must also clearly identify the brand and model proposed, provide descriptive literature, and disclose any modifications planned to meet the requirements. Other projects should be handled according to their respective bidding documents and applicable rules.<\/p>\n\n\n\n When an engine model is specified<\/strong>, first verify the actual engine assembled on the quoted complete machine. If the supplier can prove that the quoted configuration is equipped with the specified engine model, this item passes verification, though the complete machine must still meet the remaining requirements. If the supplier substitutes it with another four-stroke engine\u2014and the document allows for substitution\u2014evidence must be provided addressing the engine requirements listed in the document. For instance, if the document specifies net power and corresponding RPM, they must be compared on the same basis (apples-to-apples). If the intention is to replace the engine on an existing pump, the shaft end and mounting dimensions are also critical criteria for judging whether it can be assembled.<\/p>\n\n\n\n When the complete machine model is specified<\/strong>, comparisons must be based on the actual delivered configuration. If the document specifies both operating pressure and flow rate, check whether the proposed configuration can simultaneously meet both requirements under the specified working conditions. If the literature only lists the maximum pressure and maximum flow rate separately, making it impossible to judge whether both can be achieved simultaneously, the supplier should be required to supplement data for that specific working condition. If there are explicit requirements for the water pump, hoses, spray guns, or fittings, these should also be checked item by item against the quoted configuration.<\/p>\n\n\n\n Manufacturer literature can illustrate the difference between these two layers of evidence. Honda lists the GX200 as a 4-stroke gasoline engine. However, in SIMPSON’s literature, pressure washers equipped with the GX200 have configurations nominally rated at 3000 PSI \/ 3.0 GPM, as well as configurations nominally rated at 3500 PSI \/ 2.5 GPM. Even with the identical engine model, the nominal pressure and flow rate of the complete machine can differ.<\/p>\n\n\n\n Require the supplier to submit a point-by-point comparison table (compliance matrix), clearly stating the tender requirements, the actual supplied model and configuration, corresponding evidence, and any deviations. Each piece of evidence should be traceable to a specific model and configuration. Engine specifications can verify the stroke type and listed power; complete machine specifications or test data can verify the machine’s output; and the configuration list can verify the included accessories. If the submitted literature covers an entire product series, ask the supplier to indicate exactly which page corresponds to the version being quoted.<\/p>\n\n\n\n Example:<\/strong> Suppose the document allows equivalent products and requires the pressure washer to achieve a minimum flow rate at a specified operating pressure. The supplier submits an engine specification sheet and a water pump catalog. The former can prove the engine is a four-stroke, and the latter can demonstrate the nominal capacity of the water pump. However, if neither document provides the flow rate of the quoted complete machine<\/em> at the specified pressure, this item still lacks evidence. At this point, you can request supplemental data for the complete machine in that exact configuration according to project procedures. If the supplemented data shows that the flow rate falls below the mandatory threshold, this model cannot be classified as a qualified substitute.<\/p>\n\n\n\n Evaluation records should clearly distinguish between “lack of evidence” and “confirmed non-compliant.” Whether supplemental materials can be provided in the former situation depends on the clarification methods and time limits permitted by the project. The latter situation must be handled strictly according to the bidding document and cannot be compensated for simply because both are four-stroke engines or because the alternative bid price is lower.<\/p>\n\n\n\n If still in the bidding or evaluation phase:<\/strong> First, separate the specified model and the substitute model in the quotation sheet, clearly stating their respective actual supply configurations. When the document permits substitution, submit the point-by-point comparison table and any missing evidence to the designated evaluation party. When the document’s wording is unclear, submit written questions first, explicitly pointing out which clause lists the model, whether the intended replacement applies to the engine or the complete machine, and the substitution conditions that need to be confirmed.<\/p>\n\n\n\n If the contract or purchase order has already locked in the model:<\/strong> Before proposing a change, first check the variation (change order) clauses and approval authority. Submit the original model, the proposed replacement model, configuration differences, and verification materials, while explicitly listing the contracts and acceptance items affected by the change. Update the purchase order and acceptance checklist only after obtaining the formal variation approval required by the contract.<\/p>\n\n\n\n If the bidding document explicitly requires a specified model and lacks an applicable substitution clause, the quotation and procurement must be based on that specified model. When the document permits proposing an “or equal” (equivalent) item, another four-stroke model can be submitted as a substitution proposal; however, whether it can be accepted for a qualified
