Abstract: With the rapid development of economy, the construction industry presents a good development prospect. As an important part of the healthy and sustainable development of the national economy, its development level has far-reaching influence. Civil engineering, as an important part of building engineering, its construction quality is also very important, which has a far-reaching impact on other engineering construction parts. Therefore, in the development of civil engineering construction activities, the preparation of construction drawing budget is an important and difficult content in construction management, and it is also an important measure that affects the orderly completion of civil engineering construction activities. Therefore, this paper mainly analyzes the key points for attention in the budget preparation of civil construction drawings of construction projects, and expounds the construction key points in combination with the actual situation, in order to seek reasonable countermeasures and ensure the quality of budget preparation.

The compilation of civil construction drawing budget of building engineering has a far-reaching impact on the project cost, and plays an important role in understanding the orderly development of civil construction activities and ensuring the overall construction quality of the project. In civil construction, the construction unit needs to pay more attention to the preparation of construction drawing budget, and can carry out targeted work according to the main points in construction according to the actual situation, so as to realize the purpose of civil construction drawing budget preparation. From this point of view, it is very necessary to strengthen the research on matters needing attention in budgeting of civil construction drawings, which has certain reference value for subsequent theoretical research and practical work.

1 Overview of budgeting for civil engineering construction drawings

The budget of civil construction drawing of building engineering is a pre-design for the application of construction funds, which mainly plays a certain guiding and reference role for the investment of construction funds in combination with the actual situation, so as to ensure that all aspects of engineering construction can be implemented and improve the construction quality. As far as the budget of civil construction drawing is concerned, it can be regarded as budget design. Based on the engineering drawings of the design unit, the budget design is carried out in combination with the capital investment in the whole construction stage of the project, including building materials, human resources, machinery and equipment, etc. Comprehensive consideration, design the overall cost of civil engineering in advance, and provide reference for the subsequent investment in civil engineering. It can be said that the budget preparation of civil construction drawing has a far-reaching impact on civil engineering, and it needs the support of corresponding systems to ensure the smooth completion of the budget preparation activities of civil construction drawing.

There are two main methods for compiling the budget of civil construction drawing, namely, material method and unit price method. The unit price method mainly refers to the unified price list compiled by the unit price of civil engineering, based on the corresponding multiplication of all aspects of civil engineering, and the sum of the results is the total cost of the final civil engineering, including the sum of indirect costs of some activities, and the sum of the two is the final total budget price of civil engineering drawings. The physical method is the same as the unit price method, but the direct cost calculation of each link of construction is different, mainly multiplying the unit price of each link of civil engineering with the estimated unit consumption, and adding the multiplication results to get the final total cost of the project. This method is more flexible and can be dynamically adjusted and set according to the actual situation.

2 civil construction drawing budget points

The budget preparation of civil construction drawing involves complex contents. In order to ensure the orderly development of construction drawing budget preparation activities, it is necessary to make budget preparation according to the actual situation. Points for attention can be divided into drawing design, budget freezing framework, cost information and dosage software.

2. 1 Understand the design requirements of drawings

Civil construction drawing design is the basis of construction drawing budget preparation, and construction drawing budget preparation needs to take civil construction drawing as the main reference and carry out targeted work. Therefore, budget preparers need to deeply understand and fully interpret the construction design drawings, so as to ensure that they can master the key contents of the construction drawings on the basis of understanding the design drawings, and fully understand and master the structure and laws of the project, so as to ensure that the subsequent construction drawing budget preparation work is carried out in an orderly manner, avoid vague and uninvited problems, and provide a solid foundation for the construction drawing budget preparation work.

2.2 improve the ability to grasp the budget quota

The most important content in the preparation of construction drawing budget is to determine the budget quota. How to grasp the budget quota reasonably and skillfully is very important, which requires higher professional quality of designers. Only by reasonably grasping the budget quota can we compile a more accurate budget quota for civil construction activities. Only by fully grasping the measurement standard and quota of engineering quantity can the compilers have a deeper understanding and grasp of each link, solve the problems that are easy to occur reasonably and effectively, pay more attention to budget review and respond more flexibly. Budget quota mainly includes mandatory quota and guiding quota of construction industry. As far as China's current market development is concerned, it is more appropriate to adopt the know quota. According to the technical specifications of engineering construction and the use of building materials, other factors are only used as reference, not as the main basis. In the process of budget preparation activities, the construction unit should first consider whether it is directly used as a quota preparation standard or as a reference. Only in this way can we better provide a solid guarantee for the fixed budget.

Budget quota plays a very important role in civil buildings, and both the construction unit and the construction unit need to analyze it according to the budget quota. Only in this way can the bidding work be carried out effectively. Therefore, the two sides of the teammate budget quota project need to reach a unified understanding through full consultation, and the budget quota will really have legal effect after signing the contract, and the budget quota will be dynamically adjusted according to the actual situation. However, it should be noted that the established budget quota can be dynamically adjusted and cannot be completely overturned, otherwise it will cause contradictions in project construction and affect the orderly development of subsequent project activities. Therefore, only when the budget maker fully grasps the budget quota can he provide a reasonable reference for the subsequent civil engineering budget quota.

2.3 do a good job of cost data collection.

When carrying out their work, budget personnel need to fully collect and sort out the project cost information, provide the basis for budget preparation according to the collected project cost information, and check the budget preparation work repeatedly after integrating the information to ensure that the budget preparation work can be completed smoothly and avoid unnecessary problems and affect the accuracy of budget quota setting. Therefore, the budget preparers should first collect and sort out the relevant data and materials related to this project, and choose the budgeting methods, norms and measurement standards according to the budgeting experience of other projects, so as to determine the final budget expenses as the main reference for the budgeting of this project, and carry out the budgeting work in a targeted manner. At the same time, budget preparers should also make an in-depth analysis of the data collected in budget preparation to see if there are any problems that need to be solved.

2.4 Choose reasonable engineering survey software.

The selection of engineering quantity measurement software has great influence on the budget quota of civil engineering. Because the calculation of content engineering quantity involves many contents and is very complicated, it is necessary to choose reasonable measurement software to ensure the accuracy and speed of calculation results and ensure the orderly development of subsequent budget preparation. The calculation of engineering quantity by graphic calculation software is mainly realized by budget personnel according to their own measurement rules. According to the drawing tool, the budget personnel determine the position of each building component of the project, input it into the measurement software by attribute method, measure the building components, and finally summarize the measurement results of each part to get the final measurement result.

3 Conclusion

To sum up, it is very important to prepare the budget of civil construction drawing of building engineering, which directly affects the overall cost and economic benefit of the project. Therefore, budget makers need to firmly grasp several key issues to ensure that budget preparation activities can be successfully completed.
