03 — Engineering Consultancy
Structure, calculated to the last joint.
In-house structural steel design, finite element analysis and full CAD documentation — turning a permitted site into a buildable, calculated, certifiable structure. Every project carries its full calculation package from day one.

Steel structure design per EN 1993.
/engineering/steelEC3 / EN 1993Full design scope — Part 1-1 (general rules), 1-5 (plated elements), 1-8 (joints), 2 (bridges), 3 (towers & masts). All load combinations per Annex A/B.
Member DesignBeams, columns, bracing, trusses and moment frames — bending, shear, axial force and buckling checks. Class 1–4 sections covered.
Connection DesignBolted and welded joints — base plates, end plates, fin plates and gussets. Full EC3 Part 1-8 calculation output.
Fire & FatigueEC3 Part 1-2 (fire) and Part 1-9 (fatigue) where required by project scope or insurer.

/engineering/feaANSYS
Linear and non-linear static, modal and buckling analyses. Shell, solid and beam elements. Full result extraction and verification reports.
RFEM 6
Complete structural frame analysis with EC3 code-check integration. Surface models, load combinations, design optimisation and full Eurocode output.
Robot Structural
BIM-linked analysis model. Direct exchange with Revit and Tekla for integrated structural–architectural workflow.
Every project scope that involves a non-trivial load path — long-span steel, cantilevered structures, connections under dynamic load — is run through FEA before detailing begins. Results are delivered as a documented calculation report, not just a model file.

FEA deformation plot — retail park roof
Stăuceni retail park — 12,000 m² steel roof
3D shell+beam FEA model of the entire roof structure under wind, snow and UDL combinations. Buckling analysis run on main rafter members. EC3 code checks applied to all critical elements. Result: 14% material saving vs preliminary design.
| Parameter | Result |
|---|---|
| Max deflection (span/250) | L/287 ✓ |
| Critical buckling mode | λ = 3.6 |
| Max utilisation ratio | 0.87 |
| Steel tonnage (optimised) | 184 t |
FEA portal frame — logistics hub
Vatra logistics hub — 18,500 m² portal frames
Multi-bay portal frame analysis including crane loading and differential settlement. Non-linear geometric analysis confirmed stability under asymmetric loading. Haunch connections designed and checked to EC3 1-8.
| Parameter | Result |
|---|---|
| Bay width | 24 m |
| Eaves height | 9.5 m |
| Critical load case | Wind + crane |
| Max sway (h/150) | h/212 ✓ |
FEA cantilever canopy analysis
Centru mixed-use — 8.4 m cantilever canopy
Dynamic wind analysis on a long-span welded cantilever canopy. Modal analysis identified a frequency of 1.8 Hz — above pedestrian excitation threshold. Connection design at root verified under full moment reversal.
| Parameter | Result |
|---|---|
| Cantilever span | 8.4 m |
| Fundamental frequency | 1.8 Hz ✓ |
| Tip deflection | 18 mm |
| Root moment | 312 kN·m |
