Structural design, BIM models and reinforcement drawings for apartment buildings, halls and refurbishments. We work for developers, architects and contractors across Slovakia and can also take on lead design services.
We compare structural options and take concrete and reinforcement quantities from the model before a contractor is chosen. For developers →
Architects
A structural system without needless conflicts
We help verify spans, slab thicknesses, the position of load-bearing walls, penetrations and coordination between disciplines while the design is still taking shape. For architects →
Design practices
Extra capacity and specialist reach
We can help with analysis, a BIM model, reinforcement drawings, a design review or a specific FEM task. Reinforcement in BIM →
Construction companies
Clear answers for the site
We deal with construction queries, changes during the build, alternative details and technical advice on the actual problem.
Structural manufacturers
Timber trusses and steel members
We prepare the calculations, load checks, bearing details and documentation that fabrication and erection can actually use.
Private clients
Houses and refurbishments
We handle the structural design of a new build, an added storey, a conversion, an opening in a load-bearing wall, or the assessment of an existing structure.
Our approach
We use BIM as a working tool, not as a visualisation.
In a BIM environment we build a model of the load-bearing structure that can be used for coordination, clash detection, drawing production and the rest of the project. The goal is not a good-looking 3D model but a technically usable basis for design, construction and checking.
Where it makes sense, we can prepare a model carrying information about the structure, materials and reinforcement so that it stays useful after the building is finished.
Model of the load-bearing structure
A three-dimensional structural model linked to drawings, schedules and coordination with architecture and services.
Clash detection
Clashes between structure, penetrations and services are resolved in the design — not on site, where changes cost more.
Link to analysis
The model is not a picture on its own. We use it as the basis for analysis, coordination and design checking.
Reinforcement drawings
Reinforcement is detailed so that both the designer and the contractor can read it. We pay attention to layers, annotation, details and checking.
Coordination between disciplines
We work with the architect, the building-services engineer and the lead designer through DWG, IFC or Revit, depending on what the project allows.
GFRP and new materials
Expertise in non-corroding GFRP reinforcement, backed by doctoral research and an experimental programme.
Scope of work
Services
02
Reinforced concrete structures
Foundations, slabs, walls, columns, beams, stairs and reinforcement details. Structural calculations and drawings for both permitting and construction.
Steel structures
Design of steel members, connections, beams, columns, frames and secondary steelwork, with the emphasis on details that can be fabricated.
Timber structures
Roof structures, timber floors, structural systems, anchorage and connection details. The design follows both the architecture and what the builder can deliver.
FEM and advanced analysis
For demanding tasks we use three-dimensional FEM models, non-linear analysis and methods proportionate to the risk and complexity of the structure.
BIM & reinforcement drawings
Modelling of structures and reinforcement in Revit. Outputs are prepared for coordination, checking and real use on site.
Automation
We develop our own Python and pyRevit tools for repetitive work, schedules, reinforcement and document checking.
Trussed roofs
Analysis of trussed roofs, checks on loading, bearings and bracing, and the documentation needed for fabrication and erection.
Assessments and diagnostics
Structural assessment of existing buildings for refurbishments, new openings, added storeys, layout changes or increased loading.
Technical consulting
Advice for architects, investors and contractors on the structural system, details, alternatives and construction queries.
Lead design services
We take on coordination of architecture, structures and building services in one model. We do the structural design ourselves; scope and responsibilities are set in the offer. More →
Preliminary hall design
Structural system, foundations, movement joints and quantities before the precast manufacturer is chosen. More →
Design check
Independent structural check and a second opinion where things are unclear or savings are needed. More →

Technology behind the design
03
Revit / BIM
Model, drawings and coordination
We use Revit for the structural model, drawing production, reinforcement, detail checking and data exchange.
Advanced FEM
Global models and assessments
For more complex structures we build a three-dimensional model and work through load combinations and design effects.
Non-linear FEM
Non-linear analysis of concrete
For specific tasks we can use non-linear models, cracking, material non-linearity and expert assessment.
Python / pyRevit
Our own automation
Routine steps in Revit and in reinforcement drawings are automated with tools we wrote ourselves. Less repetition, more checking.
Eurocodes
Design to the applicable standards
Calculations and assessments follow the relevant standards, with the emphasis on back-checking and a clear technical justification.
Engineering judgement
The model must match reality
Software is only a tool. What decides the outcome is the right simplification, the boundary conditions, the loading and the interpretation of the results.
A digital practice
One model — from survey to drawings
·
We build the structural design on one spatial model. Analysis, reinforcement and documentation all come directly from it, while our own Revit tools and AI-assisted checks handle the routine. On one apartment building this produced 25 drawings, 741 m³ of concrete and about 76 t of reinforcement in the schedules.
Survey data — PDF, DWG, survey of the existing structure
BIM model — Revit, LOD 300–400, the structure in three dimensions
Analysis — advanced FEM analysis, the whole building in one mesh
Reinforcement — modelled bar by bar: cover, anchorage, clashes
Documentation — our own Revit tools: tagging, dimensions and schedules generated automatically
Checking — AI-assisted consistency checks of drawings and reports
Reinforcement at LOD 400IFC exchange with the architectIn-house tool development for RevitAI in both preparing and checking documentation
BESCon Tools
We build our own tools for Revit.
Our own tools cut routine errors, keep reinforcement drawings consistent and speed up document production. For you that means a cleaner and more reliable result.
Consistent reinforcement drawings
Uniform tagging, layers and annotation across the whole project.
Fewer routine errors
Repetitive steps are done by tools, not by hand — less room for mistakes.
Faster documentation
Automated schedules and tagging cut the production time.
Clearer for the site
Drawings that both the designer and the contractor can follow.
Where a project cannot be published in full, we show anonymised output with no client-sensitive data. The point is to show how we think, the standard of the documentation and the technical depth of the design. Buying an older house? What to check (in Slovak) →
BIM / Case series
House — from model to reinforcement
The whole sequence on one project: the structural model, the loading, and the reinforcement of ring beams, floor slab, gable and foundations.
FEM / Timber roof
A house and its roof as one whole
Walls, floors and roof in a single mesh — the house is assessed as a whole, not element by element.
BIM / Case series
Apartment building — from model to reinforcement
One building in five steps: the physical model of the structure, the analysis mesh, the structural frame, reinforcement modelled bar by bar, and the model with its boundary conditions. The same model carries both the analysis and the drawings — nothing is drawn twice.
Research / GFRP
GFRP reinforcement — research and testing
Long-term testing of concrete beams with GFRP reinforcement at the Slovak University of Technology. We apply what we learn wherever steel would corrode. GFRP reinforcement in concrete (in Slovak) →
Timber / Trusses
Trussed roof — from model to fabrication
A 3D model of the roof, the setting-out plan and truss fabrication. Reactions are tracked truss by truss — the basis for the ring beam and the anchorage. Timber trussed roofs (in Slovak) →
Assessment / Diagnostics
Site inspections and structural defects
Cracks in masonry and concrete, corrosion, degraded surfaces and opening-up — a documented record of the actual condition is the basis of any assessment and repair design. When is a crack serious? (in Slovak) →
Construction / Concrete
Reinforcement on site
Checking the reinforcement before the pour — column cages, slab mats, laps and spacers against the drawings.
Production / Precast
Precasting and quality control
Unit production, concrete placement and test specimens — the structural design carries on into the factory.

★★★★★
Structural assessment of an older house
"Mr Blaho got in touch himself and kept in contact throughout. He explained in detail how it would work, the inspection happened on the date promised, he explained everything in terms I understood and proposed measures I will certainly carry out."
Juraj H.
★★★★★
Structural assessment of a flat — refurbishment
"Prompt and trouble-free communication, an inspection in person and comments incorporated for the housing association. A very pleasant, customer-focused approach."
Chartered civil engineer for structural design · SKSI I3
BESCon — Blaho Engineering Solution for Construction — was set up to bring practical structural engineering, BIM design and analysis tools together into documentation people can actually use. We are not an anonymous drawing office. Behind every design there is a named engineer who understands the analysis, the detail and the construction.
Specialisation: reinforced concrete, steel and timber structures, reinforcement drawings, BIM/Revit, FEM analysis, assessments and technical consulting.
PDF, DWG, IFC, photographs, a site plan or a short description of what you intend. For refurbishments, photographs of the existing structure help as well.
