(1) Adopt strategic procurement. Before launching a project tender, by establishing long-term strategic partnerships with capable material suppliers and contractors, and by adopting strategic procurement methods, it is possible to fully leverage the advantages of procurement in order to reduce the overall cost of the project. (2) Expand the foundation for cooperation with contractors and suppliers; by continuously adding competitive partners, enhance competition among bidding entities and effectively control costs. (3) Establishing a standardized product cost information database in collaboration with the engineering and design departments helps to improve the cost-performance ratio of designed products. By participating in the design of standardized engineering products, a value analysis of costs is conducted on the basis of meeting the product’s functional requirements, so as to align the product’s market positioning and achieve reasonable costs, thereby giving the product the best cost-performance ratio. And conduct unified bidding for the standardized design of products. (4) Prepare a comprehensive bidding and procurement plan for each project, coordinate the effective execution of all such bidding and procurement tasks, and ensure strict adherence to the planned procedures for control and implementation. (5) Develop tender documents and contract templates that are suitable for a unified project orientation, and make prior arrangements and conduct rationality analyses regarding key aspects of the bidding, such as contract payment methods, timeline requirements, technical specifications for project equipment, and the division of work packages. (7) Monitor the time requirements for tendering and procurement projects in a timely manner, and implement them strictly in accordance with the overall plan for project tendering and procurement. (8) For bidding on the same project, the level or grade of the recommended bidding entities should be kept as consistent as possible, with minimal differences, in order to enhance competitiveness. (9) Prepare the tender documents for each individual project by collecting, organizing, and reviewing the tender drawings, technical requirements for the project, and bid submissions. At the same time, timely follow-up and implementation are carried out for the preparation of the base price list. (10) Establish and improve the technical requirements for relevant tendering and procurement projects, to ensure optimization and quality control from technical and quality perspectives. For example: the required technical parameters for equipment such as elevators and distribution boxes, etc. (11) In accordance with the requirements of project bidding, it is necessary to promptly organize pre-bidding meetings, answer questions related to the bidding process, and carry out document reviews for each individual bidding task. (12) Carry out proper bidding and business negotiation work. Establish a foundation for negotiating facts and data information. Negotiation is not about simply pressing for lower prices, but rather negotiation based on a thorough understanding of the market prices for such projects and one’s own pricing, along with long-term considerations. By analyzing the overall cost of the tendered project, evaluating suppliers, and assessing the market, it provides valuable factual and statistical information for negotiations, helping to identify one’s own bargaining advantages and thus taking control of the entire negotiation process. It helps to control costs effectively. (13) Establish a mechanism for evaluating and selecting bids; it is recommended to adopt the principle of awarding the contract to the bidder with the most reasonable low price. That is, it takes into account the overall corporate strength of the bidding entity while effectively controlling project costs. (14) For projects with historical pricing and a relatively small scale, under the same conditions, could priority be given to allowing the original winning bidder to expand the scope of work and carry out the construction? Reduce bidding time and improve efficiency. (15) Establish and improve the bidding and procurement processes and systems, and continuously optimize the bidding procedures and methods. For example: through open bidding or electronic procurement methods (16), and by establishing appropriate assessment mechanisms. The rewards and penalties for partner organizations should be clear and explicit, and strictly enforced throughout the contract fulfillment process. It helps to increase the level of trust between both parties.
