In order to survive and develop in the competition, and to ensure the realization of the commitments in the contract terms with the owner, construction enterprises must strengthen project management, determine reasonable cost targets, construction period targets, and quality targets, and use technical measures, economic measures, and contracts. Measures and organizational measures effectively control the "three major goals", so as to achieve better economic and social benefits.
Clarify and handle the opposite and unified relationship of the "three major goals": in the process of project construction, if a higher quality goal is established, the main factors affecting the quality of the construction project must be controlled accordingly, in order to ensure the realization of the set goal. First, the organizers directly involved in the construction, the commanders and the operators should be completed by people with high technical level, strong skills and rich experience. The labor price will inevitably be increased, and the treatment will be increased accordingly. will increase the number of working days consumed. The selection and rational use of materials are also directly related to the quality. Only by selecting materials with good texture, good materials and strong performance, and scientifically using them in a reasonable position, can the established quality goals be achieved, but the cost of procurement will often increase. Three", the purchase time is relatively extended. In some cases, there will be shutdowns and waiting for materials, which will affect the construction period. The extension of the construction period also affects the turnover of funds. Second, the requirements for construction machinery are also different. Old equipment must be replaced, and new equipment with good performance and high application of advanced technology should be put into use. The one-time investment is large, and the turnover and amortization costs are high. In order to improve the construction quality, it is necessary to formulate a feasible construction plan according to the actual project, and take correct technical measures. To solve the construction problems, it is necessary to take necessary measures and spend enough time to complete. Third, environmental factors are also the main reason for affecting the quality of the project. Engineering technical environment such as engineering geology, hydrology, and meteorology; management environment such as quality assurance system and quality management system; labor environment such as labor mix, workplace, and working face; all have a direct impact on project quality, and these environmental factors are complex and changeable Only by taking corresponding measures can it become an excellent environment for quality assurance. During the construction process, there may also be changes in drawings and materials that are not in place in time, which will undoubtedly increase the cost of the project. Therefore, the quality of the previous process and sub-projects directly affects the quality of subsequent processes and sub-projects. Thus, the cost is increased, the construction period is prolonged, and the money is wasted. Of course, this situation is not uncommon. This is the opposite side of the "three major goals". At the same time, due to the high quality achieved, the rework caused by quality defects will be reduced, the construction period will be relatively shortened, the rework cost will be avoided, and the maintenance and protection cost during the warranty period will also be reduced. This is the unifying aspect of the "three goals".
In the construction process, we often encounter two situations. First, when a shorter construction period target is determined, the main factors affecting the progress must be controlled accordingly. There are many factors that affect the progress, such as human factors, technical factors, material and equipment factors, climate factors, environmental factors and so on. Among them, human factors are the most important interference factors. In order to convert these unfavorable factors into favorable factors for the construction period, some technical measures taken will inevitably affect the quality and cost. For example, in order to catch up with the construction period, artificially increasing the number of night shifts and the number of people will result in an increase in nighttime construction costs and management costs, and a reduction in quality standards. Second, a lower cost target has been established. Using materials of inferior quality and low price, construction personnel can only hire workers with low technical level and low quality due to low wages. If this is the case, it will not only fail to guarantee the quality of the project, but also increase the cost and prolong the construction period, making it difficult to achieve the goals of controlling quality, cost and construction period.
To sum up, the "three major goals" of quality, cost and construction period are opposed and unified. Therefore, when determining the target value, it is impossible to achieve the optimal three objectives, and it is impossible to make each objective absolutely satisfactory. When determining each goal, the influence of other goals should be considered, and various aspects should be analyzed and compared to optimize the goal. It should be noted that the safety and reliability of the project, the functional objectives of use, and the qualified construction quality must be guaranteed first. On this basis, we strive to optimize the entire target system and meet the relative satisfaction principle of determining the target value. For the final goal set, the project should reach a high-quality level, so as to satisfy the users and the society. Lay a solid foundation for the enterprise in the competition.
