First, the division of packaging
If the target of a project subject to tender is to be divided into several packages, the following points should be paid attention to in the division of packages:
(1) Assemble devices with high correlation into a package;
(2) A sufficient number of potential bidders should be considered to be able to participate in the bidding;
(3) Interface requirements between packaging equipment should be clear;
(4) When necessary, imported equipment (or together with relevant domestic equipment) can be packaged separately;
(5) It is beneficial to write technical specifications independently;
(6) It is conducive to bidding, bid evaluation, award, implementation and acceptance respectively;
(7) It is beneficial to reduce the procurement cost;
(8) The bidding process will not drag on for too long;
(nine) the bidding, bid evaluation and award system;
(10) does not restrict bidding, but it can restrict winning bids and allow bidders to provide cross discounts.
Second, the reference standard
The technical standards put forward in any procurement document cannot exhaust all requirements, so we should learn to quote national standards and industry standards as the closed loop of requirements. Otherwise, these requirements, such as what materials to use, especially when the acceptance method cannot be reached, will be disputed by both parties, because the methods adopted are different, so the following points should be paid attention to when determining the reference standards in the technical specifications of the bidding documents:
(1) For non-basic requirements, national standards and/or industry standards (for domestic bidding projects) should generally be cited; Or refer to the standards formulated by the International Organization for Standardization (ISO) and/or the International Electrotechnical Commission (IEC) (for international bidding projects, you can also refer to the national standards equivalent to (IDT) or modified (MOD)) to ensure that enough bidders participate in the bidding.
(2) For basic requirements (such as voltage and frequency of equipment, etc.). ), should be unified reference to national standards, otherwise in the future, due to the different power systems, special substation equipment or special power generation and distribution equipment will be provided for the purchased equipment.
(3) For special requirements that can only be applied to national standards or enterprise standards, the content of specific requirements can be directly written into technical specifications without quoting the standard number. If possible, it is appropriate to change the determined index requirements to interval or boundary index requirements.
Third, the technical requirements for equipment
When putting forward technical requirements for equipment, we should pay attention to the following eight points:
(1) Pay attention to the rationality of the index system, which has two meanings. First, the index system should strive to be complete; Second, indicators should be coordinated, because different technical indicators are often contradictory, with gains and losses. At this time, we must weigh the indicators, avoid simple stacking or combination of high indicators, especially avoid summarizing the best parameters from various product samples, because such products do not actually exist.
(2) The supplier's product samples or enterprise standards cannot be used as the blueprint of the technical specifications of the bidding documents, otherwise the bidding work will lose its impartiality and competitiveness, which is also very unfavorable to the tenderee.
(3) The technical requirements of energy should be quantified as much as possible, and too simple or general qualitative requirements often lead to the difficulty in distinguishing advantages from disadvantages in bid evaluation. Once there are objections or complaints, the difficulty of handling them will greatly increase.
(4) For the equipment matched with the related system equipment, the software and hardware requirements of the interface (interface) must be specified, and the bidder must explicitly promise to integrate with other related system equipment. The communication protocol of the interface (interface) must be unconditionally open, otherwise it may be subject to people in the future system transformation, expansion or upgrade.
(5) Pay attention to the verifiability of important technical indicators, and define inspection standards or methods.
(6) For key technical indicators or technical indicators that may have different understandings, definitions of terms should be added to avoid mistakes in bid evaluation decision-making due to different understandings.
(7) Pay attention to the difference between system bidding and equipment bidding. On the premise of ensuring that the system functions and indicators are met, the bidder shall be given reasonable autonomy in equipment configuration.
(8) If the supporting facilities provided by the owner are likely to become the restrictive factors, it shall be stated in the tender documents; For the technical parameters of supporting facilities that the designer needs to obtain, a special form can be designed to require the bidder to fill in truthfully (the relevant parameters involve the life cycle cost that needs to be considered in the bid evaluation process), so as to avoid the dilemma that the supporting facilities cannot meet after the winning bidder determines.
