(1) Investigation data of natural conditions. Used to solve related problems caused by weather (freezing, flood, strong wind, hail, etc.). ) and transportation; It is also used to arrange drainage ditches for surface water and groundwater; Determine the layout of facilities that are flammable, explosive and harmful to human health.
(2) The vertical design data and earthwork balance diagram of the construction area. It is used to solve the layout of hydropower pipelines, earthwork filling and excavation, and the location of soil removal.
(3) Rental of houses, sites, processing equipment and living facilities around the construction unit and the construction site. Used to determine the area and space position required for temporary buildings and facilities.
2. Design data:
(1) general plan. Used to correctly determine the location of temporary buildings and other facilities, as well as the information needed to build transportation roads and solve on-site drainage;
(2) Location of all existing and proposed underground and above-ground pipelines. It is used to determine the relationship between the utilization or demolition of the original pipeline and the laying of the new pipeline and other projects, and pay attention to the fact that temporary buildings cannot be erected at the location of the proposed pipeline.
3, the contents of the construction drawing budget:
Construction drawing budget includes unit project budget, single project budget and total construction project budget. The unit project budget is based on the construction drawing design documents and the current budget quota; Labor, materials, equipment, machinery and other expenses quota and budget price data.
It can generally be summarized as the construction drawing budget of a single project.
Extended data
Basis for preparation of construction drawing budget:
(1) Atlas of construction drawings, specifications and standards: it is an important basis for drawing up the construction drawing budget.
(2) Current budget quota and unit valuation table: it is the main basis for compiling construction drawing budget, determining sub-projects of sub-projects, calculating engineering quantity, selecting unit valuation table and calculating direct engineering cost.
(3) Construction organization design or construction scheme: including relevant materials necessary for preparing construction drawing budget.
(4) Budget price and regulation of price adjustment for materials, labor and machinery: The reasonable determination of budget price and regulation of price adjustment for materials, labor and machinery is an important basis for the preparation of construction drawing budget.
(5) Construction and installation engineering cost quota: it is the cost quota and calculation procedure stipulated by provinces, municipalities, autonomous regions and various professional departments.
Budget staff's work manual and related reference books: it is an indispensable basis for compiling construction drawing budget.
