. Through these work, the staff can calculate the workload and reduce the error in the budget; The third stage is the summary of related expenses. Because the construction cost is complex and the amount is relatively large, the staff can use the computer to carry out it, which is convenient and accurate. However, when operating the computer manually, the compiler should also ensure the accuracy of input formulas and numbers. For some large projects, once there is a very small error in the calculation process, it will have a negative impact on the whole construction process. In addition to the work of the staff, there are other factors that will cause the deviation of the compilation results. Because the preparation of pre-settlement is completed before the project starts, it is an expectation, so the deviation is inevitable.

In the engineering stage, there are several common influencing factors. The first is the price of materials. Because the construction materials are purchased from the market, the market is changing at any time, and the construction company and staff can't intervene. The price of materials used in the pre-settlement stage may change in the actual construction stage. The second is the influence of national policies. Building construction is a long-term work, which needs to be done step by step. However, the society is changing and the national policies are constantly being adjusted, which may have an impact on the results of pre-settlement, such as the wages of construction personnel or the use costs of equipment. In the design stage of building engineering, designers usually carry out their own work according to technical specifications, standards and means. If any conditions change, the design will also change, but this change is also unpredictable, leading to the deviation of the pre-settlement results. For the calculation of engineering quantity, the clarity of construction drawings and other factors determine the accuracy of the calculation results of engineering quantity. For all kinds of equipment used in construction, due to fierce market competition, the quotation of merchants will change with the progress of the project, which also causes the inaccurate settlement results of the project budget.

2. Some problems in the project budget and settlement.

Due to the influence of various factors and unpredictability, there are some problems in the pre-settlement work. The first is the problem of cutting corners. In construction projects, the supply of materials is limited by regulations, but the price will change with the change of the market. Some construction units only pay attention to economic benefits, ignoring the quality of materials and the quality of the project itself, using poor quality products, in order to obtain more economic benefits, cancel or change the project without reporting. Some construction units use bargaining instead of fixed quotation in a few projects, which will also lead to false price in project budget and settlement. Due to the time limit, some construction units demand other fees from the construction company on this condition, and fabricate various reasons to demand fees during the project.

3 strengthen the project budget and settlement strategy

In view of the above problems, construction enterprises need to adopt a variety of strategies to do a good job in pre-settlement:

1) Bidding: Before the project starts, it is necessary to determine the engineering quantity, engineering design, organization, quota and charging standard, that is, the bidding budget, which is also the basis for the construction unit to calculate the price. Bidding is the basic stage of the project. When preparing the tender budget, we should be familiar with the market and understand the quota, so as to prepare the tender budget correctly and effectively. First of all, we should be familiar with the information, and relevant personnel should fully collect the information, such as bidding documents, contract terms, cost standards, categories, etc. , and should also pay attention to the part of the cost plan that can be adjusted and the calculation unit of the quota; In the stage of engineering quantity calculation and summary, attention should be paid to the application of budget units. Engineering quantity is the main basis of budgeting, so the accuracy of budgeting depends largely on the accuracy of engineering quantity calculation, and relevant personnel should calculate accurately and clearly. Relevant formulas and rules must be kept in mind and applied accurately. You can also use computer software to calculate, but you must ensure the accuracy of the input data.

2) Visa change: During the construction process, if there is any design change, on-site visa work is required. Because it involves the construction process, the content is complex and the cost is difficult to determine. In the process of construction, the following situations often occur: clearing obstacles, natural disasters and external forces, which are common, but these contents are not included in the construction drawing. To do a good job of visa change, we should pay attention to three aspects: "truthfulness, completeness and strictness", in which truthfulness refers to confirming that the visa and change are in compliance with the regulations and clearly expressed, and the duplicate visa should be removed in time; Completeness means that the visa must be signed by the design unit, the owner and the supervisor at the same time, and these signatures are complete before the visa can take effect; Seepage prevention refers to comprehensiveness. Budget personnel should investigate the construction site to determine the change of engineering quantity, and then carry out visa work to prevent leakage.

3) Project settlement: At the completion stage of the project, the construction enterprise should do a good job in project settlement, not only to ensure that the settlement conforms to laws and regulations, but also to ensure that the settlement conforms to the contract, and comprehensively and clearly count the settlement contents of each project. If there is any dispute between the two parties to the contract, they should adjust it to the relevant departments in time. Engineering settlement data should be filed for future reference. Construction enterprises should strengthen management, equip professionals for pre-settlement, and organize supervision. If the owner defaults on the settlement, he should report it to the relevant departments in time and solve it in time.

4) Personnel quality: The budget personnel are the main persons in charge of the project budget settlement, and the various aspects and complexity of the budget settlement put forward high requirements for the level of the budget personnel. Construction enterprises should strengthen the ability training of budget personnel in various ways to ensure the comprehensive quality and knowledge level of personnel, so as to ensure the accuracy and effectiveness of the pre-settlement results. To sum up, there will inevitably be some problems in the pre-settlement work of construction projects. Construction enterprises should pay attention to management, and ensure that the pre-settlement results meet the final settlement of the project to the maximum extent through various measures, so as to ensure the accuracy of the pre-settlement of the project, which is also the guarantee of economic benefits for construction enterprises.
