The cost calculation of greening projects belongs to the category of construction projects, and the competent department is the Municipal Construction Committee. Judging from the government's management goal, it is a task to standardize the valuation method of project cost and gradually cultivate and promote the orderly transformation of construction market to market economy by means of reform. From the current management point of view, in the greening construction projects, the greening markets such as general units, families, flower arrangement and potted art flowers have little impact on national investment. At present, the method of using seasonal changes has been adopted, and buyers and sellers are free to set prices. The flower market prices regularly published by various flower markets are for the reference of buyers and sellers when conducting transactions. At present, a series of guiding regulations and standards issued by relevant government departments are still adopted for greening planting projects invested by the government or enterprises, and they are actively and steadily developing in the direction of market economy. As far as the varieties of seedlings are concerned, there are hundreds of green planting projects with various appearances. From the engineering point of view, the construction site, planting method and construction season are different. Is there any rule in the calculation of greening project cost? What standards and regulations are there at present? What are the calculation methods? See how the old drivers solve the construction cost. (II) Composition of greening project cost According to the provisions of the municipal construction project quota management station, the cost management department under the Municipal Construction Committee, the cost of greening planting project consists of two major contents: one is the direct cost of the project; The second is the indirect cost of the project. As the name implies, the direct cost of the project refers to the direct cost of completing the greening and planting project, which mainly includes three aspects. 1. Labor costs: including all labor costs such as lightering, digging holes, changing soil, planting, covering soil, water conservation, fencing and maintenance within one month after the seedlings are purchased to the construction site. 2. Material cost: including the cost of seedlings of different varieties and specifications, as well as the cost of auxiliary materials necessary for planting. Auxiliary materials include water for seedling irrigation, straw rope for trunk protection, lead wire, and various materials such as bamboo piles, wooden piles and cement piles. 3. Mechanical expenses: including the mechanical loss expenses caused by lifting, resetting and righting when large-sized seedlings cannot be manually lifted. Labor, materials and machinery are all stipulated in the quota. In general, it is not allowed to change at will. However, the quota is based on normal construction methods to determine labor, materials and machinery costs. Due to the ever-changing conditions and climate of the construction project, the quota also stipulates that for the uncertain factors beyond the quota, Party A and Party B shall separately increase the project cost according to the actual situation of the construction site, but only after mutual consultation and agreement, and supplementary terms shall be clearly added in the construction contract, can the project cost be increased. The indirect cost of the project refers to other expenses that the construction enterprise must charge after the greening planting project is completed, and it is an indispensable part of the greening project cost. Including: expenditure and management expenses of technical management personnel of construction enterprises, legitimate profits of enterprises and taxes paid to the state (or higher management departments). How much the indirect cost of the project is charged is based on the scale of the greening planting project, which is uniformly and clearly stipulated by the municipal construction project quota management station and cannot be increased or decreased at will. (3) The basis for calculating the cost of greening planting project must first have a complete construction design of greening planting project. The design of construction design drawings shall be designed by Party A (the owner) with the qualification of greening design. According to the investor's specific environment, topography, ornamental and use requirements and investment amount, they will design construction drawings that are not only beneficial to the function of plant growth, ornamental and use, but also ensure the rational use of funds, and allocate the number of seedlings of different varieties and specifications to achieve the expected effect of the investor. Secondly, there should be market price information of seedlings that matches the project construction period. The price of seedlings changes according to the fluctuation of market price in different construction time, so the expected cost of the project must be calculated according to the current market supply price of seedlings before construction, that is, the box calculation scheme of how much it costs to complete a green planting project. The market price information of a seedling is subject to the price information released by the municipal construction engineering quota management station, and there are generally two ways. 1, release the project cost information in the first month of each quarter. 2. According to last year's seedling price, comprehensively determine the budget adjustment price of engineering seedling materials. The quota currently used by xx is the version of Quota of Garden Construction Project in a City 1993, and the corresponding documents generally refer to the relevant documents of greening planting project published after 1993. For example, earthwork cost documents, budget adjustment price of engineering seedling materials in different years, supplementary quota of greening maintenance, etc. (IV) Calculation method of budget cost of greening planting project Calculation of budget cost of greening planting project, the total cost of a greening planting project should be calculated separately as follows. Total cost of greening and planting project: direct cost 1 seedling cost; 2. Earthwork cost; 3 planting costs (including green space consolidation costs) indirect costs (including management fees, corporate profits, taxes and other costs).
