Which part of the cost in the bid quotation of mine shaft engineering refers to, and should it be included in the total cost when quoting?

1. What quantities need to be calculated for a complete mine engineering budget? The following quantities need to be calculated: 1. Direct cost: it is divided into the following three parts: fixed direct cost, other direct cost and on-site funds. 1, fixed direct fee: according to the parameters such as section, lithology, slope, support type, construction method (general excavation or comprehensive excavation), apply mine roadway quota, calculate labor, machinery and materials, and then get a budget unit price; Budget unit price × engineering quota direct fee a2. Other direct costs b include the following five items (1): secondary handling fee for materials; (two) the use of production tools and appliances; (3) inspection and test fees; (4) Project positioning survey, pile delivery at the project site and site cleaning fees; (5) Training fees for special jobs; (3) site fee C (1) temporary construction fee; (2) Site management fee; (3) The large discrepancy is closely related to the water inflow, heating period and gas content.

Third, the practical basis for the preparation of mine shaft engineering budget and bill of quantities valuation: Wu Zongwu 2 Part I Basic knowledge of mine shaft engineering construction drawing budget Market economy can not be separated from commodities, which are products exchanged by workers, and the price of commodities is the monetary expression of product value. Construction engineering products, like other products, are also commodities and materialized economic and technological activities of social reproduction. Since it is a commodity, there must be a price. The price of construction projects cannot be determined by a unified pricing law like other products, such as industrial products, agricultural products and daily necessities. This is mainly because of the singleness and diversity of construction projects, especially mine construction projects, and the variability of construction sites. Therefore, the construction project cost can only be determined by controlling the budget quota, that is, the amount, and it can be used as a technical economy to calculate and determine the construction project price. Construction project budget is a subject of how to calculate, analyze and manage construction project investment. At present, the project budget is guided by the market economy theory in the primary stage of socialism, and it is a comprehensive subject combining engineering technology with economic theory. It involves not only natural science, such as the determination and selection of various technical parameters, the calculation of material and machinery consumption, etc. This is a technical science, but when determining the price of products, it also involves the organization and allocation of labor force and the full utilization of labor productivity, which also belongs to social science. The composition of various expenses in product prices is currently in the primary stage of socialism. It is an organic combination of engineering technical parameters and price economic data, and an effective way to determine the project cost under the condition of market economy. There are many disciplines of construction engineering budget, which are classified from large departments, including civil construction, railway construction, highway and bridge construction, water conservancy and hydropower construction, post and telecommunications construction, mine construction, port, aviation, civil air defense construction and so on. In mine construction, it is divided into coal, metallurgy, nonferrous metals, chemicals, building materials and gold. The following briefly introduces the basic knowledge of construction drawing budget of three non-ferrous mines. I. Meaning, function and compilation basis of construction drawing budget The construction drawing budget is an economic document used to determine the total construction cost of the project from preliminary preparation to completion, acceptance and delivery. It shows the total investment required for the project construction and the cost of the project. It is a special method and form to determine the price of building products and a monetary expression of the value of building products. The function of construction drawing budget: 1, which is the basis for determining the cost of engineering construction project and transferring it to fixed assets. 2. Under the control of preliminary design budget, the basis for evaluating the economic rationality of project design is the basis for project supervision to control project investment. 3, is to determine the project contract price, project settlement or the basis for signing a cost contract. 4. It is the basis for the owner to determine the pre-tender estimate of the project and the bidding quotation of the construction enterprise. 5. It is the basis of economic accounting and project cost assessment within construction enterprises. The quality of construction drawing budget directly affects the level of project cost and the accuracy of investment. Therefore, before compiling the construction drawing budget, the compilers must fully grasp the information and meet the following conditions: 1, approved preliminary design specifications and a complete set of construction drawings; 2, project contracting construction contract; 3, engineering geology, hydrological data 4, engineering construction scheme, construction organization design or unit engineering construction organization design; 5. Budget quota, cost quota and relevant regulations applicable to this project promulgated by the state or relevant departments; 6, where the engineering materials, wind, water budget price, semi-finished structural products price; 7. Rules applicable to engineering quantity calculation; 8. The order price of non-standard equipment, standard equipment and complete sets of equipment or the ex-factory price of equipment issued by relevant departments; Second, the cost composition and meaning of the construction drawing budget: According to the 2008 Edition "Cost Quota of Construction and Installation Project and Other Cost Quota of Engineering Construction in Nonferrous Metals Industry", the cost of construction and installation project consists of direct cost, indirect cost, profit and tax.

Notice on printing and distributing the composition of gtgt project of ltlt construction and installation project; the composition of this fee is different from that of the original project. The content of this adjustment is: 1. In order to meet the needs of competitive pricing in bidding for construction and installation projects, other direct costs, temporary facilities costs and non-entity consumption costs in the original direct costs are combined into measures costs. 2.
