施工方案施工工艺不仅要满足施工合理性要求，还要满足施工安全、经济优化等

Construction plan The construction process must not only meet the requirements of construction rationality, but also meet the requirements of construction safety and economic optimization. Construction companies should choose mature construction technology together with their own advantages, choose a suitable construction plan for the project, and achieve the overall best goal of schedule quality, that is, the purpose of reasonable control of construction costs. The use of a large number of backward construction techniques may make the construction cost uncontrollable. Material price fluctuations undoubtedly have the greatest impact on project costs during the construction phase. Construction units are often insensitive to material price changes and insufficient changes, leading to an increase in the risk of some thermal changes. The main control method is controlled by contract, which must be strictly controlled to determine the price of materials. Combining real-time material market conditions, grasping fluctuating trends, ensuring construction implementation, and providing a strong basis. Changes in the engineering process often occur, so all changes must be strictly checked. It is strictly forbidden to expand the scale of the project through disguise, project standards, etc. Changes need to be confirmed and signed by multiple parties to ensure that each change can be reasonably complied with.

Construction program construction process should not only meet the requirements of construction rationality, but also meet the requirements of construction safety, economic optimization and so on. Construction enterprises should choose a mature construction process with their own advantages, choose the construction plan suitable for the project, and achieve the overall best goal of the quality of progress, that is, the purpose of reasonable control of construction costs. The use of a large number of backward construction processes may make the construction costs out of control. The fluctuation of material price undoubtedly has the greatest impact on the construction phase engineering cost, the construction unit is often insensitive to the material price change, the change is insufficient, leading to the rising risk of some thermal change. The main means of control through contract control, must be strictly controlled, determine the price of materials. Combined with real-time material market conditions, grasp the trend of fluctuations, to ensure the implementation of construction, to provide a strong basis. Changes in the course of the project also occur frequently, so all changes should be strictly checked. It is strictly forbidden to expand the project scale project standards through camouflage, etc. Changes require multiple confirmations and signatures to ensure that each change is properly complied with.

The construction scheme and construction technology should not only meet the requirements of construction rationality, but also meet the requirements of construction safety and economic optimization. The construction enterprises should choose the mature construction technology with their own advantages, choose the construction scheme suitable for the project, and achieve the overall best goal of schedule quality, that is, the purpose of reasonable control of construction cost. Using a large number of backward construction technology may make the construction cost uncontrollable. The fluctuation of material price undoubtedly has the greatest impact on the project cost in the construction stage. The construction unit is often insensitive to the change of material price, which leads to the rising risk of some thermal changes. The main control means are controlled by contract, and must be strictly controlled to determine the material price. Combined with the real-time material market, grasp the fluctuation trend, ensure the construction implementation, and provide a strong basis. Changes often occur in the process of engineering, so all changes should be strictly checked. It is strictly forbidden to expand the scale of the project by camouflage, project standards, etc. Changes need to be confirmed and signed by multiple parties to ensure that each change can be reasonably observed.
