Minor repairs
The projects include, inter alia:
1. Leaks, patches, water, ridges, etc。
2. Refurbishment of steel, wooden doors and windows, replacement of hardware, glass, window veils, paint, etc。
3. Refurbishment of the floor floors of the building, replacement of individual logs, etc。
4. Repair of internal and external walls, dusting and painting of ceilings, windowsills, etc。
5. The removal of bricks and the repair of local walls, individual arches and the replacement of individual beams。
6. The extraction of individual beams, the sarcastic line on the roof, the foot of the wooden pole, the fixing of wood stairs, etc。
7. Disruption of equipment such as water, electricity, heating, gas and maintenance of spare parts。
8 - sewage pipes, repair of boreholes, repair of gavages, scattered water, fallow pipes, etc。
9. Inspection of houses, temporary reinforcement of hazardous components, etc。
Main features:
The volume is wide, scattered, sudden and time-critical, the project is simple, less labour-intensive and less repair costs。
Main tasks:
Maintenance of the functioning of the house and its equipment through daily maintenance works to ensure its normal use。
2. The maintenance of end-user warranties and the organization of sporadic maintenance provide timely repair of the damage that occurred and prevent further damage from causing greater damage。
3. Organize regular inspections of houses to ascertain the state of their destruction, start with maintenance, prevent accidents, and systematically organize major and intermediate repairs, providing information on surveys and construction。
Engineering
Partial maintenance is performed at a cost of less than 20 per cent of the cost of the new construction of the same structure in the building, and the maintenance work to maintain the size and structure of the original building is medium。
These include, inter alia:
1. A small number of structural components have formed hazardous sites。
2. Houses generally damaged that require partial repair。
3. Public living equipment for the whole building requires partial replacement, modifications, new assembly works and individual project maintenance。
Main features:
The basic requirement for more than 70 per cent of built-up buildings to meet the basic standards of well-being is that the site is more concentrated, the project is smaller, the work is larger, the work is planned and cyclical。
Major repairs
Where partial removal or demolition of the main structures and building equipment is required, the repair work for the construction of more than 25 per cent of the new structure in the building at a single cost is major。
Main elements:
1. Most of the main structure is seriously damaged, with collapsed or partially endangered houses。
2. The common living equipment of the whole house must be replaced by a pipe, requiring modifications and new housing。
3. The improvement of living conditions requires partial alterations and additions。
4. Houses need to be reinforced with a specific earthquake-resistant structure。
Main features:
The basic requirement of a centralized, full-scale, large-scale, costly and holistic project is that the house, after major repairs, must meet basic standards of well-being。
Integrated maintenance
The one-time repairs required for the planned repairs, including large, medium and small repairs, to be carried out in more than one block of buildings or large single buildings at a cost of more than 20 per cent of the new construction cost for the building in the same building。
Main elements:
1. Most of the (barrells) were seriously damaged, or were generally damaged, and required systematic repairs
2. Planned maintenance works will need to be carried out to change the face (barrel)。
Main features:
Larger, complete, long and costly. The basic requirement is that a piece of (a) house, which has been repaired, must meet the criteria of basic integrity or wellness。
Renovation work
(up-to-date renovation works)
Renovation works are those that require full demolition (including in situ renovations or alterations) or renovations using a small number of main components。
Main elements:
1. The main structure is completely or largely damaged, loss of normal use and risk of collapse。
2. Houses that continue to be used as a result of natural disasters; main structures, with inadequate perimeter structures and no repair value。
3. Buildings located in areas of steep and ready slopes or in areas where the terrain is more incipient and where water is long-standing and inaccessible。
4. Houses that need to be demolished and rehabilitated within the framework of the national infrastructure plan。
