More and more companies manage complex steel structures. A hall, warehouse, hangar, or trestle structure operates under load around the clock. It is natural that questions arise about safety, load capacity, and repair planning.
In this text we explain what a technical opinion on steel structures is, what it includes, and how the process works. You will learn what tests we perform and how to prepare the facility and documentation before commissioning the work.
Who needs a technical opinion?
A technical opinion is useful when you need a reliable basis for technical, legal, or business decisions.
- Owners and managers of halls, warehouses, hangars, and buildings with steel structures
- Investors planning expansion, changes in loads, or a change in the building’s function
- General contractors and design offices needing data for design or strengthening works
- Users of structures with load-bearing cables and tension systems, including membrane structures
- Maintenance and safety departments planning inspections and repairs
What a Technical Opinion on Steel Structures Includes
The document is delivered as a clear and structured report. It includes the results of the assessment together with recommendations.
- Description of the technical condition of elements, nodes, and connections
- Geometric inventory and a damage map with photographic documentation
- Results of non-destructive NDT testing and control measurements
- Wall thickness and coating thickness measurements, corrosion assessment, and evaluation of anti-corrosion protection
- Analysis of the causes of irregularities and risk classification
- Load capacity calculations for elements and nodes together with conclusions
- Recommendations for repairs, strengthening, and protective measures with action priorities
- A general schedule of works and a plan for monitoring and periodic inspections
How the Technical Condition Assessment of Steel Structures Is Carried Out
The assessment combines visual inspection, measurements, and NDT testing. When required, we perform load capacity calculations and propose strengthening solutions. We also carry out work at height using rope access techniques.
Stages of Visual Inspection and Measurement
- Review of documentation and definition of the objective of the technical opinion
- Preparation of a safety plan and access to hard-to-reach areas
- Close inspection of elements, nodes, and connections
- Inventory of deformations, displacements, and corrosion losses
- Measurements of dimensions, coating thickness, and wall thickness
- Verification of the condition of connectors, welds, and anti-corrosion protection
NDT Testing and Load Capacity Calculations
- NDT testing adapted to the material and the type of connections
- Control measurements to detect changes over time
- Strength analysis of elements and nodes
- Load capacity calculations in accordance with current requirements and best practices
- Conclusions and recommendations based on test results and calculations
Non-Destructive Testing and Control Measurements for Steel Structures
We use methods that do not damage the structure while providing a reliable picture of its condition.
- VT – visual inspection of welds and elements at close range
- MT – magnetic particle testing of welds and weld-adjacent zones
- UT – ultrasonic detection of discontinuities and thickness measurements
- PT – penetrant testing for detecting surface cracks
- RT – radiographic testing of welds where technically justified
- Measurement of protective coating thickness and pull-off adhesion testing
- Assessment of surface contamination and readiness for painting
- Hardness measurement and local identification of steel grade in justified cases
- Measurement of displacements and deflections, control of geometry and deviations
- MRT testing of steel ropes using the LRM system, in cooperation with the LRM-NDE Laboratory
Repairs and Strengthening of Steel Structures After Analysis
After the assessment we can proceed with repairs and strengthening works. We also perform work at height.
- Replacement or repair of elements and connectors, filling of material losses
- Strengthening with plates, reinforcement plates, and rib stiffeners, including structural nodes
- Repair and additional welding of connections, edge preparation and weld inspection
- Anti-corrosion protection, abrasive blasting cleaning, and painting
- Adjustment of tension systems, replacement of ropes and hardware
- Installation of temporary and permanent protection, including safety nets
- Straightening of elements and stabilization of displacements
- Quality supervision and final acceptance with as-built documentation
Technical Requirements and Documents Needed to Order a Technical Opinion
To prepare a quotation and schedule efficiently, basic information about the facility and the objective of the opinion is required.
- Description of the facility and its function, including expected loads
- Scope of the requested opinion and completion deadline, agreed during contact
- Information about access limitations and work at height
- List of available design and as-built documentation
- Information about production downtime and possible service windows
- Data on previous failures, repairs, and inspections
Design Documentation and Access to the Facility
- Design documentation, drawings, as-built changes, and material descriptions
- Reports from previous tests, including NDT, and inspection reports
- Documentation of protective coatings and technical data sheets of paint systems
- Operating manuals, technical documentation, and assembly diagrams
- Ensuring access to key zones. Rope access or other methods arranged as required
Quality Assurance and Safety of Steel Structures
We focus on safe work organization and quality control at every stage.
- A team with rope access qualifications and certified equipment
- HSE procedures and a worksite protection plan, also in operating facilities
- A consistent testing plan, approval path, and engineering supervision
- Cooperation with a specialized laboratory for MRT testing of steel ropes
- Reports with complete photographic documentation and clear conclusions
- Possibility of continued cooperation for repairs, strengthening, and periodic inspections

Pricing is individual. We usually start with a short consultation and a review of the documentation. If necessary, we perform a site visit. We operate in Poland and throughout the European Union. We can plan periodic inspections as well as repair actions after issuing the technical opinion. The timeline and scope are agreed during the discussion.
A well-prepared technical opinion on steel structures organizes decision-making and reduces risk. It provides a clear picture of the condition of the facility and concrete steps for today and tomorrow. It is an investment in safety, operational continuity, and reliable operation.
