Technical Inspection of Buildings in Lviv: Structural Diagnostics in Conditions of Historic Urban Development and Complex Soils

Technical Inspection of Buildings in Lviv: Structural Diagnostics in Conditions of Historic Urban Development and Complex Soils

Lviv is a city with a unique architectural heritage, where most buildings in the central part have been in operation for over 100–150 years. A significant portion of objects was erected in the 19th and early 20th centuries using limestone, brickwork, and wooden floor slabs. Complex engineering and geological conditions — the presence of loess soils, a high groundwater level in certain areas, and a significant number of basement premises — create additional loads on foundations and load-bearing structures. A technical inspection of buildings in Lviv makes it possible to identify hidden defects, assess the residual resource of structures, and substantiate decisions regarding repair, reconstruction, or reinforcement. The procedure is carried out in accordance with the requirements of DBN V.1.2-14:2018 and DSTU 9273:2024.

When a Technical Inspection of Buildings in Lviv is Necessary

Technical inspections of buildings in Lviv are carried out in cases provided for by DSTU-N B V.1.2-18:2016. The main grounds for commissioning are:

• purchase or sale of a real estate object — to confirm the absence of critical defects that could significantly affect market value;
• reconstruction, storey superstructure additions, or change of functional purpose — to determine the feasibility of implementing design solutions without compromising structural reliability;
• identification of signs of emergency condition — cracks, settlements, water infiltration, deformations indicating progressive destruction;
• expiration of the standard operational lifespan — for buildings erected before the 1950s;
• the need to obtain a technical conclusion for submission to local self-government bodies or insurance companies.

What a Technical Inspection of a Building in Lviv Includes

A comprehensive engineering inspection of structures covers all load-bearing and enclosing structures, engineering systems, and improvement elements:

1. Foundation inspection — assessment of type, embedment depth, presence of deformations, cracks, waterlogging traces, condition of waterproofing and drainage systems. Uneven settlement, groundwater impact, and frost heaving are investigated. For Lviv, this stage is critical due to widespread loess soils, which lose load-bearing capacity when moistened.
2. Inspection of load-bearing structures — walls, columns, beams, trusses, floor slabs. The presence of cracks, distortions, deviations from the vertical, corrosion damage, rotting, and biological damage is determined.
3. Roofing and facade inspection — checking tightness, condition of roofing material, truss system, drainage; assessment of facade panels, plaster, insulation.
4. Thermal imaging inspection — identifying thermal bridges, insulation breaches, wall freezing, leaks in window and door units, and hidden moisture zones.
5. Instrumental inspection — use of thermal imagers, moisture meters, testers to assess the condition of electrical networks.
6. Engineering system analysis — assessment of water supply, sewerage, heating, power supply, and ventilation systems for operability and compliance with standards.

When inspecting historic buildings in Lviv, special attention is paid to the condition of wooden floor slabs and truss systems, which are often affected by rot or pest insects. Modern non-destructive testing methods are used to identify hidden structural defects. Read more about how to identify hidden defects and document them properly in our material.

How a Technical Inspection of a Building is Conducted

The technical inspection procedure is structured according to the following algorithm:

1. Preparatory stage. Analysis of existing design, as-built, and operational documentation. The scope and methods of research are determined, and the site visit schedule is agreed upon.
2. Visual inspection. Initial walkthrough of all premises, basements, attics, and facades with the recording of obvious defects (cracks, delamination, corrosion, leak traces). Photographic documentation of problem areas is performed, and a preliminary defect map is compiled.
3. Instrumental measurements. Application of specialized equipment to obtain quantitative characteristics of structural condition.
4. Preparation of a technical report. Documenting all results with detailed descriptions, tables, charts, conclusions, and recommendations. The report is signed by certified engineers and, if necessary, registered in the EDESSB.

What the Customer Receives

Based on the inspection results, the customer receives a technical report registered in the Unified State Electronic System in the Construction Sector (EDESSB). The document contains:

• description of the object’s actual condition — detailed analysis of each structural element with calculations and photographic documentation;
• technical condition category with assessment of the residual structural lifespan;
• list of identified defects indicating the nature, location, and probable causes of each;
• recommendations for restoration, reinforcement, or dismantling.

The process of preparing a technical report on the inspection of building structures is key for submitting documents to local self-government bodies or insurance companies. In cases where destruction is critical, dismantling or demolition of buildings and structures may be required, which also necessitates proper technical justification.

Cost and Timelines of Inspection Execution

The cost of a technical inspection of buildings in Lviv is determined individually for each facility. Key pricing factors are the area and number of storeys of the building, structural complexity, the need to use specialized equipment, accessibility of structural elements for inspection, and the availability of design documentation. Work duration depends on the complexity of the object — for an apartment or a small private house, 2 working days from the site visit to the finished report are usually sufficient; for commercial or industrial objects where laboratory sample testing is required, timelines can reach 1–3 weeks. GlobalBud Ukraine provides a full cycle of technical inspections of real estate objects with subsequent registration of the report in the EDESSB.

Frequently Asked Questions

Is it mandatory to conduct a technical inspection of a historic building in Lviv before reconstruction?

Yes, according to DSTU-N Б В.1.2-18:2016, a technical inspection is mandatory before major repairs or reconstruction of buildings, especially those with the status of architectural monuments. For historic objects in Lviv, the requirements of cultural heritage protection authorities are additionally taken into account.

What documents confirm the results of a technical inspection?

The inspection results are formatted as a technical report, which is registered in the EDESSB. This document has legal force and can be used for submission to local self-government bodies, insurance companies, or court.

Is it possible to conduct a technical inspection of a building in Lviv without design documentation?

Yes, the inspection is carried out based on the actual condition of the structures. The absence of design documentation is not an obstacle to performing the work, although having a technical passport significantly simplifies the diagnostic process.

What is the frequency of technical inspections for buildings in Lviv?

For objects with an operational lifespan of over 50 years, it is recommended to conduct inspections with a frequency specified in the technical passport or determined by the owner’s decision. For historic buildings in Lviv, it is advisable to conduct inspections at least once every 5–10 years.
