12. Presents the stages in planning urban construction land height.a. overall planning stage of urban construction Background height master plan to build an entire city-¸ Nh price reasonable level of spatial planning-Calculate determine building elevations -The expected surface water drainage research, identify high speed network control.-To propose specific solutions for complex terrain areas-Your computer land mass, scheduled to coordinate ground and estimated cost.b. detailed planning stages (planning sector)Detailed planning 1/2000 Preliminary design elevations, complete background-Materialize toward the city's master plan-Determine the altitude control, vertical gradient and the length of the street-Identify the plane construction in the background design-Draw some sections dictionary hỡnh-Calculate the mass of the Earth-Estimated cost of Detailed planning 1/500-1/200Highly technical design complete background-Determine the exact altitude of streets intersecting, falls, the square, the flat surface design of the zone, the altitude of the yards, determine the elevation angle of the floor of the House, 1st floor, entrance elevations-Resolve the relationship between the road and its construction-A mass of land, CoordinatorDETERMINE THE CONSTRUCTION HEIGHT Conditions control -Flooding situation, attenuated by the municipality and the safeguards for the municipality (religious background; embankment + pump stations; embankment + tribute to regulate ...) -Tidal mode -Hydro agricultural drain system of the urban periphery Determine the construction height -Hydrological calculation determines the relationship between flood flow and the ability to appear -Determine the frequency of design based on the nature and urban function -Determine the flow and water level calculations -Determine the altitude control HminXD = Htt + 0.5 (m)13. The presentation using standard mode and use the watera. water standards -Water standard is the basic parameter to determine the scale of the capacitywater supply stations as the system design:+ Water standard of livingThe average count per capita (litres/person. day and night). Water demand in the housing depends on the level of sanitary engineering equipment, climate conditions, living and other conditions of each locality. + Water standard of production determined on the basis of the design documents, or compare with the similar production conditions. + Public service of Water + Water losses+ Water for requires its own water treatment plant+ Fire water standards-Standard water calculation is saved the average consumption per person in one day and night on the biggest water user's follow each stage of construction.
