Bidding can improve the economic benefits of construction projects, ensure the quality of construction projects and shorten the payback period of construction investment. The construction unit can make full use of bidding as an effective means to control the project cost. It is required to provide a bill of quantities when bidding, and the compilation of the bill of quantities should follow the principles of objectivity, fairness, science and rationality. According to the calculation rules promulgated by the state or local government, that is, unified project division method, unified measurement unit and unified engineering quantity calculation rules, the list is calculated and sorted out according to the design drawings.
2. Cultivate a high-quality engineering cost team with both ability and political integrity.
Project cost management is a comprehensive subject, involving technology, economy, laws and regulations and management knowledge. This requires that the project cost personnel should not only have strong financial budget ability, but also have certain engineering design knowledge and construction experience, as well as comprehensive scientific knowledge such as materials and mechanical construction technology, so as to pay attention to the calculation of engineering quantity. At the same time, we should have a strong sense of professionalism and noble professional ethics. Especially in the situation that the market economy system is gradually improved and the investment trend is diversified, there is an urgent need for a group of high-quality talents who can provide scientific decision-making basis for the project and manage the project cost, which requires the project cost personnel to learn new knowledge through various channels, give play to their initiative in work practice, innovate constantly and improve the technical level and quality of the budget. At present, China has implemented the qualification access system for project cost personnel, and has successively issued relevant specific regulations. Engineering cost personnel should improve their own quality as soon as possible to meet the needs of market economy.
3. Standardize the bidding documents and create a fair competitive market environment.
Bidding should be an orderly market behavior in project budget competition. Through bidding in the construction market, the construction unit and the contractor can enter the construction market for fair trade and equal competition, and avoid and reduce unhealthy practices such as bribery in the process of project contracting and contracting, thus ensuring the project quality and improving the investment benefit. The construction unit shall, according to the inherent characteristics and operating rules of project bidding, reasonably determine the bidding scope, select the ideal bidding method, analyze the construction scheme in detail, fully consider the unforeseeable factors, prepare a scientific pre-tender estimate or bill of quantities, and do a good job in pricing and controlling the bidding work. Adopt reasonable bid evaluation and calibration methods to optimize the winning bidder and ensure that the project cost is controlled within the limit.
4. Design in strict accordance with the standard and dynamically control the project cost. Doing well the cost control in the engineering design stage is the key to effectively control the engineering cost.
Design standard is an important technical specification for national economic construction and an important basis for engineering construction survey, design, construction and acceptance. It is necessary for all kinds of architectural design departments to formulate and implement corresponding design standards and norms at different levels to improve the investment control level in the design stage. In the design process, the project cost personnel should closely cooperate with the designers, make a comparative analysis of the project investment in time, and feed back the cost information. If necessary, they should demonstrate with engineering designers and construction management personnel to make a reasonable budget. Implementing standard design in the process of project design can promote the level of industrialization and speed up the project progress. Similarly, standards should be implemented in the project budget. According to the standard budget, materials can be saved and construction investment can be reduced. It is necessary to carry out quota design, strengthen dynamic management in quota design, and realize dynamic control and management of design specifications, design standards, engineering quantities and budget indicators.
5, strict contract management, reduce engineering changes and claims.
Construction contract is the basis of cost control in construction stage. Only by strictly signing the construction contract and strengthening the contract management in the construction process can we ensure the rationality and legality of the contract cost, reduce the disputes between Party A and Party B during the contract performance, safeguard the interests of both parties and effectively control the project investment cost. After the contract is signed, the management of contract documents should be done well. As an extension and interpretation of the contract, the contract and supplementary contract agreement, as well as regular on-site meeting minutes and work contact sheets must be kept intact. At the same time, establish technical files, make a dynamic analysis of the contract implementation, and take active measures according to the analysis results. Because of the high risk, long cycle and many unpredictable factors in construction projects, it is particularly important to strengthen contract management and strictly perform contracts. In the process of project implementation, the cost personnel should take the initiative to control and strictly review the project changes. For the projects that must be changed, it is necessary to analyze in detail the increase and decrease of engineering quantity and cost, calculate the impact of each change on the total investment, and adjust the project cost determined in the original contract. At the same time, it is necessary to correctly predict the claims that may be caused in the construction process, and be forward-looking to the claims, so as to effectively avoid the occurrence of excessive claims.
