1, learn to read construction drawings, which is the basic skill. As long as it is an engineering-related major, you should have studied it at school, and then you will be skilled at the scene. If you haven't studied, you must learn from scratch. 2. Understand relevant processes. Part of the construction technology is learned at school, and part of it is observed and studied on the spot. New technologies emerge one after another, all of which are learning by doing. If you don't know, ask an engineer. 3, familiar with the calculation rules of quantities. The quota is generally specified in detail. If you don't understand, please consult the old budget officer. 4, familiar with the quota. This is a guy who eats, so you must be familiar with it. Turn the quota if you have nothing to do. 5. Understand relevant laws and policies. Every industry and every place has some rules to understand. The competent departments of cost industry in many places have published a compilation of laws and regulations. 6, familiar with the project overview and project contract. Budget and final accounts are closely related to contracts, so you must be familiar with the corresponding contracts. 7, familiar with all kinds of materials, labor, mechanical machine-team market prices, it depends on the work slowly accumulated. 8. Be familiar with various budget quotation systems, and you will talk about it when you find this budget introduction book. 9, master the use of commonly used budget software, know the basic CAD operation. Now it's all computerized, so we must master it. 10, the last point is about personal qualities-budgeting is a meticulous and boring job with great responsibilities (all related to money), so you must be patient and careful.
