Introduction

The purpose of this coursework is to acquire building inspection skills; analysis of operating conditions; decision to carry out repairs; development of technology for repair works on the basis of technical conclusion on physical and moral condition of buildings and engineering equipment.

According to the goal, the following tasks should be solved:

- study of the location of the object in the development, the purpose and general state of the object, a brief description of the building;

- organization of technical operation and maintenance of building structures and engineering equipment of the building;

- assessment of physical wear and tear of building structures and engineering equipment of the building; or the extent of damage, destruction of the building;

- analysis of operating conditions of the building and causes of destruction or damage of structures and equipment of the facility;

- assessment of the technical condition of the building with the study of architectural, planning and volumetric solutions, building structures and engineering equipment of the building:

- Assessment of the possibility and economic feasibility of carrying out repairs that provide safe and sanitary living conditions for people;

- development of technology for operation or repair of building structures or engineering equipment of the building, reconstruction of the building or engineering system:

- systematizing and summarizing the results of the study, drawing up a schedule of technical operation for the life cycle of the building; and propose measures for maintenance of the operation facility;

- Drawing conclusions and recommendations by each student according to his/her individual assignment based on the results of the survey.

The main task of the technical management of buildings is to ensure their safety at the minimum cost of repair and maintenance. In this regard, the basis of proper operation is the assessment of the technical condition of structures and the building as a whole and their operational qualities. Assessment of the state of structures or diagnostics at various stages of the existence of buildings establishes the signs and causes of damage, allows you to identify defective, collapsing structures, determine the extent and boundaries of damage in order to repair them in a timely and high-quality manner. Thus, it is necessary to monitor the condition of the building, starting from its commissioning (acceptance control), during operation (preventive control), when defects are detected and before setting the building for overhaul.

The monitoring system provides for the creation of methods for evaluating devices and tools that allow you to determine the parameters of the technical condition and their

compliance with regulatory characteristics. The data obtained from the assessment of the state of the structures of the buildings in operation can serve as a basis for improving the quality of construction, improving the methods of erection of new buildings, their proper operation and repair. Assessment of the state of structures, methods of control and restoration of technical condition and their operational qualities make up the technical operation system.

Therefore, the introduction of scientifically sound methods, special

diagnostic instruments, standardized values of controlled parameters, as well as the development of effective repair methods, are the basis on which the technical operation of buildings and structures is based.

The object of coursework is a residential building, which is a block section of a 5-story 20-apartment private. Structural diagram with transverse and longitudinal bearing walls from panels and support of floor panels along the contour. Foundations - tape from prefabricated reinforced concrete slabs.

In plan, the building has a rectangular shape with a stairwell in the center. The block section includes one-room, two-room and three-room apartments located on five floors. Basement rooms are also provided.

Assessment of the technical condition of building structures and engineering equipment of the building and development of the main measures for its operation

Brief description of the building

Block - section 5 - storey 20 - apartment private 1-2-3-3 was commissioned in 1990 in Angarsk. This city is located in Iin the climatic subdistrict. The age of the building is 30 years. In terms of capital groups, it belongs to the I-a group - buildings with large-panel walls, floors of reinforced concrete - its service life is 150 years. The city does not belong to historical structures.

In general, the block section is planned - compact and symmetrical, formed of a rectangular volume with a small protruding part on the rear side. According to the structure of development, it is located in the settlement zone. Functionally and compositionally, the building is a volume consisting of five floors, on each of which there are 4 residential apartments: two three-room, one-room and two-room.

Characteristics of the surveyed building

Structural diagram - with transverse and longitudinal bearing walls and support of floor panels along the contour. Foundations - tape from prefabricated rails. slabs, external walls are made of single-layer ceramic-titanium-gas concrete panels, and internal walls are made of reinforced concrete panels. The floors of the object under examination are solid steel panels, partitions are made of white-aluminum concrete, 80 mm thick. Sanitary facilities-volumetric plumbing cabins made of white aluminum concrete. Stairs prefabricated g. -b. The roof is prefabricated reinforced concrete with a cold attic and an internal drain. The roof is roll-free. External doors - wooden entrance and service. Internal doors - panel structure. Windows - with triple glazing. Built-in equipment - cabinets and mezzanines. Floors in residential rooms, front rooms, kitchens - linoleum on a heat and sound insulation basis, in bathrooms - ceramic tiles. External decoration - factory decoration of panels of external walls with decorative concrete. Interior decoration - lining with wallpaper in kitchens and latrines - oil coloring of panels to height 1,8 m, above adhesive painting, facing the walls above the kitchen row with glazed tiles to a height of 60 cm, in bathrooms - panel of glazed tiles 1,8 m, within the equipment, the remaining areas are glazed tiles to a height of 15 cm and an oil panel to a height of 1.8 m, above - adhesive painting .

Characteristics of building operating conditions

The year of construction of the block section of the 5-story 20-apartment - 1990. The standard service life is 150 years. At the time of the survey, the life of the building is 30 years. During the life of the superstructure, additions and changes to the building were not carried out. The location of the building is Angensk. Air temperature is 37 wasps. Climatic area - IB. The humidity mode of the room is normal. Operating Conditions-B. The orientation of the building is latitudinal.

Organization of works

To ensure failure-free operation of all elements and systems of the building, the commission or the responsible person for the operational control of buildings and structures identifies violations and defects of the building, the owner of the building eliminates and repairs them.

Maintenance activities are carried out for each element:

Foundations - sealing of cracks, removal of surface water.

Walls - measures for closing cracks in panels, restoration of plaster layer, sealing of joints of elements.

Ladders - elimination of loose abutments of platforms and marches to walls, elimination of cracks, reinforcement of fences, handrails, railings.

Ventilation - elimination of breakage of boxes and shafts, inspection of ventilation systems, check of passability of channels, condition of exhaust screens .

Survey findings and recommendations

According to the inspection of the technical condition of the building, it can be concluded that the building as a whole is in working technical condition, physical wear - 16%. The technical condition of the water supply network, electric networks, heating and sewerage (2,3,4,5 floors) can be assessed as working.

The technical condition of the sewage system on the ground floor is assessed as emergency, therefore, it was decided to replace old cast iron pipes and risers with new polyethylene ones .

To ensure the extension of the service life of the building, it is necessary to observe the operating rules, perform current and overhaul repairs according to the schedule given in Annex 5.

- Complete replacement of cast iron pipes and risers of the sewage network on the ground floor was carried out, the volume of work - 44.6 p.m.
