(1) under the premise of meeting the needs of construction, minimize the construction land, do not occupy or occupy less farmland, the construction site layout should be compact and reasonable.
(2) Reasonable arrangement of lifting [wiki]machinery[/wiki] and construction facilities, scientific planning of construction roads, minimize transportation costs.
(3) scientifically determine the construction area and site area, minimize the cross operation between professional trades.
(4) Try to utilize permanent buildings, structures or existing facilities for construction services, reduce the construction cost of construction facilities, and try to use assembly construction facilities to improve their installation speed.
(5) the construction facilities are arranged to meet: favorable production, convenient life, safety and fire prevention and environmental protection requirements.
2. Construction of the general layout of the basis
(1) the construction project building plan, vertical layout and underground facilities layout.
(2) construction project construction deployment and the main building construction program.
(3) Construction project construction schedule, construction quality plan and construction cost plan.
(4) Construction project construction total resource plan and construction facilities plan.
(5) The scope of the construction site and the location of the water and power sources for the construction project, as well as the project safety construction and fire prevention standards.
3. Construction general layout content
(1) construction project construction land within the topography and contour lines; all above ground, underground and proposed buildings, structures and other facilities location and size.
(2) The coordinate grid of all proposed buildings, structures and other infrastructure.
(3) Arrangement of construction facilities serving the construction of the entire construction project, which includes both productive construction facilities and living construction facilities.
(4) the construction project construction necessary safety, fire prevention and environmental protection facilities layout.
4. construction master plan design steps
(1) the off-site traffic into the site
in the design of the construction master plan, must start from the determination of bulk materials, pre-products and production process equipment into the construction site of the transportation mode. When the bulk of construction materials by rail, must solve the problem of how to introduce the railroad line; when the bulk of construction materials by highway, must solve the site of large warehouses, processing yards and highway relationships; when the bulk of construction materials by water, must solve how to use the original dock and whether to add a new dock, as well as large-scale warehouses and processing yards with the dock relationship issues.
(2) to determine the location of warehouses and yards
When the use of railroads to transport bulk construction materials, the central warehouse as far as possible along the railroad line, and in front of the warehouse to leave enough loading and unloading of the front, or else to be set up in the vicinity of the railroad line of the transshipment of warehouses, and the warehouse to be set up on the same side of the site. When the use of road transport bulk construction materials, the central warehouse can be arranged in the central area of the site or close to the use of the place, such as when it is not possible to do so, it can also be arranged at the entrance to the site. Yards or warehouses for bulk local materials can be arranged near the corresponding mixing stations, prefabrication yards or processing yards. When waterways are used to transport bulk construction materials, a transfer warehouse is to be set up near the wharf.
Heavy process equipment for industrial projects, as far as possible, can be transported to the workshop near the equipment assembly yard parking, ordinary process equipment can be placed on the periphery of the workshop or other open space.
(3) determine the location of the mixing plant and processing site
When there is a special concrete transportation equipment, can be set up centrally large-scale mixing plant, the location of which can be determined using the linear planning method, or else we should be scattered small mixing plant, their location should be close to the use of the site or vertical transportation equipment.
The arrangement of various processing sites should be convenient for production, safety and fire prevention, environmental protection and less transportation costs as a principle. Usually the processing yard should be concentrated in the edge of the site, and will be arranged in the same area with the corresponding warehouse or yard.
(4) Determine the location of on-site transportation roads
According to the construction project and its corresponding location with the yard, warehouse or processing yard, carefully study the material transfer path between them and the amount of transfer, distinguish between on-site transportation road primary and secondary relationships, optimize the determination of on-site transportation road primary and secondary and the mutual location; to make use of the original or proposed permanent road as far as possible; reasonable arrangement of construction roads and the field of underground pipeline network construction sequence, to ensure that the road and underground pipeline network. The construction sequence between the construction road and the underground pipeline network in the field, to ensure that the field transportation road is always smooth; to scientifically determine the width of the field transportation road, and reasonably select the road surface structure of the transportation road.
(5) Determine the location of living construction facilities
The site-wide administrative housing should be located in the site population, in order to strengthen the external links, of course, can also be arranged in the center of the comparison, so as to facilitate the strengthening of site management. Workers living with housing should be arranged in the periphery of the site or its edge. Cultural and welfare housing should be set up in the place where the workers are concentrated or near the road that the workers must pass through. The living construction facilities are utilized as much as possible in the living base of the construction unit or other permanent buildings, and the insufficient part of them will be built according to the plan.
(6) determine the location of water and electricity pipe network and power facilities
According to the specific conditions of the construction site, first determine the type and supply of water and power supply, and then determine the lead to the site of the main pipe (line) and the branch pipe (line) supply and the form of plane layout. Their specific design steps and requirements, see this chapter 34-3-3 "construction water supply facilities" and 34-3-4 "construction power supply facilities". According to the size of the construction project, also set up the fire station, fire escape and fire hydrant.
(7) Evaluation of Construction Master Plan Indicators
In order to select an optimal plan from several feasible construction master plan options, the evaluation indicators usually used are: the total area occupied by the construction site, the land utilization rate, the construction cost of building construction facilities, the total length of the construction road, and the total length of the construction pipeline network. And on the basis of analyzing and calculating, each feasible program is comprehensively evaluated.
There are too many! Duplicated!
