22 South West Street Tower under construction

A structural engineering practice working across five continents.

Full-range structural design, finite element analysis, BIM modelling and shop drawings — from first concept to the fabrication floor. 250+ projects delivered in 14 countries from our office in Sofia.

Presence

One office in Sofia, structures standing all over the world.

Every project we have engineered, by location.

The numbers.

Capabilities

Full-range engineering, from concept to fabrication.

Structural Design

Design to the latest Eurocodes and American codes — reinforced concrete, post-tensioned concrete, steel, composite and timber structures.

FEM Modelling & Analysis

Finite element analysis for complex geometry and load paths, producing reliable and economical solutions for the most demanding structural shapes.

BIM Modelling

Model-based coordination across architecture, engineering and construction — clash-free documentation and reliable quantities from one source of truth.

3D Reinforcement Drawings

Reinforcement modelled in 3D for accurate clash detection, with bending schedules exported straight to the bending machines.

Steel Shop Drawings

High-LOD steel models producing fabrication drawings and optional NC files for CNC tooling, so production starts days after documentation.

Quantity Estimation

Advanced estimation and strict quality control for a clear, accurate forecast of construction cost and programme.

Selected work

The projects that tested the limits.

Process

One model, four deliverables.

01 / Analysis

Global model, load paths and code checks — the structural concept resolved before anything is detailed.

02 / FEM

Local finite element models for complex geometry, transfer levels and steel connections.

03 / Reinforcement

Rebar modelled in 3D — clashes eliminated on screen, bending schedules straight to the machine.

04 / IFC Detailing

Details developed at fabrication level, ready to be implemented by the steel contractor.

Collaboration

We work with the best.

People

Three managing partners. Three senior engineers and a BIM manager. Eleven structural engineers.

Based in Sofia, Bulgaria, Vibe Group provides structural engineering for residential, commercial, industrial and public developments. Our portfolio spans the USA, Europe, the Middle East, Africa and Australia.

The analysis model, the coordination model and the fabrication model are the same model. Reinforcement is modelled in 3D, so clashes are found on screen rather than on site, and bending schedules feed the bending machines without operator input. Steel is detailed at high LOD, so fabrication drawings and NC files come out of the model that was verified — not a redrawn copy of it.

That continuity is what lets a team of twenty engineers carry work from concept design through to the fabrication floor, in fourteen countries and across two code families.

Leadership & engineering

Three managing partners, three senior structural engineers, one BIM manager, eleven structural engineers — all working from one office in Sofia.
