Refers to the technical and economic documents that pre-calculate and determine the total cost of landscape engineering projects according to the contents of design documents at different design stages and related quotas, indicators and charging standards. 1. What are the components of the greening project cost? Engineering direct cost = labor cost+material cost+machinery cost? Project management fee: it shall be uniformly and clearly stipulated by the construction project quota management station and shall not be increased or decreased at will. Second, the common terms of landscape engineering cost 1) Tree: a tall tree with an independent trunk from the root, and the trunk and crown are clearly distinguished. 2) Shrub: a short tree with no obvious trunk and clumping. 3) Lianas: Plants with slender stems, which can't stand upright, can only cling to other plants or supports (such as trees and walls), winding or climbing upwards. 4) Hedge: Any regular planting form of shrubs or small trees with close plant spacing and single row or double row planting is called hedge. 5) Soil ball: bare-rooted seedlings. 6) Meter diameter: refers to the diameter of the tree (seedling) at 1 meter from the ground (meter diameter is generally adopted in actual operation). 7) DBH of trees: refers to the diameter of the trunk at 1.3m above the ground. 8) Ground diameter of shrub: refers to the diameter of the trunk at a distance of 30 cm from the ground. 9) Follow closely: temporary protection measures before planting or leaving the nursery. 3. Program for compiling budgetary estimate of landscape engineering 1) Collect all kinds of basic data needed for compilation; 2) Be familiar with construction drawings and instructions, participate in technical disclosure and solve difficult problems; 3) Familiar with the construction organization design and site conditions; 4) Learn and master the engineering budget quota and its related regulations; 5) Determine the project and calculate the engineering quantity; 6) Prepare the project budget. Determine the project budget cost, calculate the direct cost, indirect cost, profit and tax, and determine the project budget cost. 1) The cost calculation of greening and planting projects is based on the construction drawings-the design drawings of garden projects generally include: garden buildings and sketches, rocky water bodies (rockeries, rivers and lakes), landscaping (garden leveling, flower planting), roads and bridges, portal fences and other projects. 2) Construction organization design-Construction organization design is a technical document written for landscape engineering to guide construction. Its core content is how to scientifically arrange the five elements of construction: labor, materials, equipment, funds and construction methods. 3) Project budget quota-Budget quota is the main basis for determining expenses. It is a legal index compiled and issued by the state or authorized units with greater authority. V. Provisions on Calculation of Greening Project Cost The general procedure for calculating the budget cost of greening planting project is as follows: 1) According to the name, variety, specification and quantity of engineering seedlings on the construction design drawings and the corresponding unit price of seedlings in the market price information, multiply the quantity and unit price to calculate the complex price. Then add up all the complex prices and work out the total cost of seedlings needed for this project. 2) Determine the construction scheme according to the terrain elevation required by the construction design drawings and the actual situation of the terrain and soil of the construction site, calculate the amount of excavated materials that meet the design terrain elevation requirements and the drainage requirements for plant growth, and then calculate the cost of garbage soil and planting soil respectively according to the unit price of earthwork specified in the document. 3) According to the relevant provisions of the construction area and quota on the construction design drawings, calculate the labor costs required for earthwork leveling, scarifying and clearing the green space before seedling planting. According to the name, variety, specification and quantity of engineering seedlings on the construction design drawing and the corresponding base price of Buddhism. 6. According to the traditional definition, the budget quota of landscape engineering refers to the labor, materials, machinery and equipment and their capital consumption necessary to complete a certain workload of qualified products or various sub-projects in landscape engineering under normal construction conditions. The function of budget quota: 1) is the basis for compiling the construction drawing budget of landscape engineering and reasonably determining the project cost. 2) It is the basis for compiling the construction organization design and determining the amount of labor, materials and construction machinery. 3) It is the basis for compiling the unit valuation table. 4) It is the basis for construction enterprises to conduct economic accounting and analyze economic activities. 5) It is the basis of reasonable preparation of pre-tender estimate and bid quotation. 6) It is a tool for technical and economic analysis of the design scheme by the design department. 7.

If the height difference between the design floor and the natural floor is above 750px, it should be calculated according to the elevation of the natural floor. 3) Manual excavation, foundation pit and trench shall be calculated by multiplying the width and length of the cushion by the excavation depth as shown in the figure, and the unit is cubic meters. And multiplied by the grading coefficient. 4) Subgrade excavation shall be calculated in cubic meters according to the size of cushion. 5) Backfill soil shall be deducted from the volume of foundation cushion and foundation buried below the design elevation, calculated in cubic meters. 6) Residual soil or deficient soil refers to the residual soil or deficient soil after all earthwork in the construction site is balanced, calculated in cubic meters. 7) When heaping heaped-up mounds, multiply the design modeling height (average height of connecting seat) by 0.7 coefficient according to its graphic bottom area, and calculate it in cubic meters. 8) The crest of cofferdam shall be calculated in linear meters according to the length of the centerline of the crest according to different design drawings. The budget audit of landscape engineering For the cost audit of greening and planting projects, the valuer must be based on the data such as project completion drawing, project change sign-off sheet, quality acceptance and so on. , and after on-site investigation and verification, to understand the various factors in the project, before the formal review. The review work can generally be divided into three stages: engineering quantity verification, price determination verification and cost calculation verification: 1) engineering quantity verification stage-mainly to know whether the calculation data of earthwork quantity (including waste soil, planting soil, earthwork lightering in the field, etc.) is reasonable and correct in the greening and planting project, whether the earthwork quantity is a concealed project and whether the visa procedures are complete; Whether the statistics of seedling planting varieties and quantity are correct; Whether the size of seedlings meets the requirements of as-built drawings; Whether the construction quality meets the design requirements, etc. 2) Price setting verification stage-mainly to understand whether the setting of various unit prices is reasonable and in line with regulations. Including the determination of earthwork unit price, whether it meets the requirements of the document; In the calculation of earthwork volume, is there a case where low-priced earthwork is mixed with high-priced earthwork? 3) Cost calculation verification stage-mainly to know whether the project category and positioning are correct, whether the rate percentage is reasonable and whether the calculation result is correct; Whether the composition of labor, materials and machinery conforms to the provisions of the document, and whether the summary of labor quantity is correct. -Metrology of landscape engineering-Engineering metrology refers to the amount of work calculated in physical and natural units of measurement, that is, the calculated amount of work. The physical unit of measurement refers to m, ㎡,? Natural units of measurement refer to plants, bushes, pots and equivalents. How to measure a pair of young people?
