A technical inspection of buildings and structures is carried out to determine the actual condition of structural elements, identify the causes of damage, and assess whether the facility can continue to be safely operated.
Unlike a routine visual inspection, a technical inspection includes a review of documentation, visual diagnostics, instrumental measurements, and, where necessary, verification of the load-bearing capacity of structures. The result is a technical conclusion that allows the client to make an informed decision regarding repair, reconstruction, strengthening, or restrictions on the operation of the building.
A technical inspection of buildings is an engineering assessment of the condition of foundations, walls, columns, floor slabs, roofs, and other structural elements.
The task of specialists is not limited to recording cracks, corrosion, or deformation. It is necessary to determine the causes of defects, assess their effect on the load-bearing system, and establish whether the facility can be safely operated under existing or planned loads.
Technical inspection of buildings and structures is particularly important before any intervention in the structural system. Designing reconstruction works without reliable information about the existing facility may lead to an incorrect assessment of loads and inappropriate technical solutions.
An inspection of buildings and structures is carried out before reconstruction, major repairs, redevelopment, addition of new storeys, replacement of heavy equipment, or an increase in loads on floor slabs and foundations.
Cracks, deflections, tilting, corrosion, concrete deterioration, leaks, uneven settlement, and other signs of structural deterioration may also provide grounds for an inspection.
A separate inspection is required after a fire, earthquake, accident, or prolonged suspension of construction. It is also necessary if design documentation is unavailable or if the actual structures differ from the drawings.
The Urban Planning Code of the Republic of Uzbekistan regulates reconstruction works and changes to the parameters of facilities. Before such solutions are developed, reliable initial data on the condition of the existing structures must be obtained.
The work begins with a review of design and as-built documentation, as well as information about repairs, reconstruction, and changes in loads. Specialists then inspect the facility, identify its structural system, and determine which areas require more detailed examination.
A visual inspection of buildings and structures makes it possible to identify cracks, spalling, corrosion, deflections, displacement, signs of moisture penetration, and damage to connections.
All defects are recorded and linked to a specific structural element and area of the building. Based on the nature of the damage, specialists determine possible causes and define the scope of further measurements.
A visual inspection alone is not sufficient when it is necessary to determine material strength, the depth of damage, or the actual load-bearing capacity of a structure.
An instrumental inspection of buildings is carried out using measuring and diagnostic equipment.
Specialists may determine crack width, geometric parameters of structural elements, deflections, tilting, concrete strength, metal thickness, and the condition of the reinforcement cover.
If deformations are identified, geodetic measurements are performed. They help determine settlement, displacement, and deviations of structures from their design position. Specialists in geodetic surveying may be involved in such work.
A detailed inspection of buildings and structures is carried out when the initial data is insufficient to make a substantiated conclusion.
At this stage, specialists clarify the dimensions and configuration of structures, perform local openings, verify material characteristics, and assess connections. Where necessary, load-bearing capacity calculations are carried out using the actual dimensions, damage, and loads.
The scope of work depends on the structural system of the building and the purpose of the inspection.
When inspecting foundations, specialists assess their condition, settlement, and the influence of the underlying soil. Cracks in walls and distortion of openings may be related to uneven foundation settlement.
When reinforced concrete structures are inspected, specialists assess cracks, deflections, the condition of the concrete, reinforcement cover, and reinforcing steel. Concrete strength is determined using instrumental methods and, where necessary, supplemented by laboratory testing.
Inspection of steel structures includes assessment of corrosion, deformation, welded joints, and bolted connections. For brick and masonry buildings, specialists assess the condition of masonry, mortar, support zones of floor structures, and the stability of individual areas.
The presence of a crack does not automatically mean that a building is in an emergency condition.
Specialists take into account its location, direction, width, depth, and changes over time. Possible causes include foundation settlement, overloading, temperature effects, reinforcement corrosion, or violations of construction technology.
Where necessary, cracks are monitored over time. If the damage continues to develop, the rate of change is determined and measures may be introduced to restrict operation or temporarily unload the structure.
A technical inspection before reconstruction should determine whether the existing structures can withstand the new loads.
For example, when adding storeys, the foundations, load-bearing walls, columns, and floor slabs are checked. When replacing equipment, specialists assess not only the installation area but also the entire load transfer path down to the foundation.
The inspection results are used to develop repair or strengthening solutions. Such solutions are prepared as part of professional building and structural design.
After a fire, it is necessary to determine whether the materials have retained their required characteristics. High temperatures may reduce concrete strength, deform steel structures, and damage connections even when the structure appears intact from the outside.
After an earthquake, specialists inspect cracks, displacement, damage to joints, and residual deformation of the load-bearing system.
The technical condition of a building is determined on the basis of all available data, including inspection results, measurements, material characteristics, deformations, operating conditions, and calculations.
The technical condition category of structural elements should not be assigned solely on the basis of their appearance. Even a visible defect may not reduce load-bearing capacity, while concealed damage may present a serious risk.
When inspecting a building in an emergency condition, the first priority is to determine whether there is a risk of collapse and whether access restrictions, unloading, or temporary strengthening are required.
A technical conclusion based on a building inspection should contain a description of the facility, its structural system, identified defects, applied methods, measurement results, and a conclusion regarding the condition of the structures.
Photographs, diagrams showing the location of damage, instrumental inspection results, and calculations, where required, are attached to the document.
The main part of the conclusion should answer practical questions: whether the building may continue to be operated, whether repair or strengthening is required, whether reconstruction is permissible, and which restrictions must be observed.
Recommendations for strengthening structures should be based on the results of the inspection. A general recommendation without identifying the cause of damage, the affected area, and the required result is not sufficient for the development of a strengthening design.
A technical inspection determines the condition of existing structures.
Technical supervision monitors the quality of works directly during construction or reconstruction.
If defects are identified on a facility under construction, these activities complement each other. The technical inspection determines the causes and consequences of the damage, while technical supervision monitors the implementation of corrective works.
The cost of a technical building inspection depends on the area and purpose of the facility, structural system, accessibility of structural elements, condition of the documentation, and required scope of measurements.
Facilities affected by fire, earthquake, or significant deformation require more detailed diagnostics than a routine inspection before repair.
The exact cost of inspecting buildings and structures is determined after reviewing the assignment, available documentation, and preliminary information about the condition of the facility.
We carry out technical inspections of buildings and structures in Tashkent and other regions of Uzbekistan.
The scope of work may include visual and instrumental inspection, assessment of foundations and load-bearing structures, measurement of defects, evaluation of the technical condition, and preparation of a technical conclusion with recommendations.
To order a technical inspection of a building, the client should provide the address and purpose of the facility, a description of the identified problems, available documentation, and the purpose of the inspection.
A technical inspection provides reliable information about the condition of a building and allows an informed decision to be made regarding its further use.
A high-quality assessment should determine not only the presence of defects, but also the causes of their occurrence, their effect on load-bearing capacity, and the measures required for repair or strengthening.
