We design structures that stand the test of time
We design, review and supervise load-bearing structures – from calculation to the last reinforcement drawing, from foundations to roof. We work in Bosnia and Herzegovina, Croatia and Montenegro.
About
We were founded in 2020, but our engineers' experience goes back decades – on bridges, high-rise buildings, deep excavations and construction sites.
- 2020.company founded in Sarajevo
- 3locations: Sarajevo, Makarska, Podgorica
We do structures – and only structures. We design reinforced concrete, prestressed, composite, steel, timber and geotechnical structures, from the first sketch of the load-bearing system to the last reinforcement drawing. Analysis, BIM model, connection details and construction drawings are produced by the same team, so what reaches the site is exactly what was calculated.
We hold licences for design, design review and site supervision in the Federation of Bosnia and Herzegovina, Republika Srpska and Brčko District. Through iNSTRUCTA Makarska d.o.o. we work in Croatia and the wider EU market, and through iNSTRUCTA d.o.o. Podgorica in Montenegro. Our projects stand in Bosnia and Herzegovina, Croatia, Hungary, Germany, Peru, Georgia and the USA.

Services
We work exclusively on the structural part of a project – but we do all of it: structural concept, analysis, construction drawings and supervision on site.
Building construction
Residential, commercial and public buildings from concept to detailed design – in reinforced and prestressed concrete, steel, timber and composite systems.
Civil engineering
Bridges, viaducts and overpasses on motorways, urban roads and railways, and rehabilitation of bridges that have reached the end of their service life.
Structures
Static, dynamic and seismic analysis for structures where a standard solution is not enough: long spans, prestressing, complex details and connections.
Geotechnics
Foundations, excavation support, retaining walls, ground anchors and slope stability – including where the neighbouring building stands right at the edge of the excavation.
Refurbishment
Condition assessment of existing structures and design of repair, strengthening, vertical extensions and changes of use.
BIM
Structural information models in Revit, Allplan and ProtaBIM, coordination with architecture and MEP, and openBIM exchange via IFC.
Drawings
Formwork, reinforcement, post-tensioning and steel shop drawings – drawings the site can build from without further questions.
Renewables
Wind turbine foundations, solar plant substructures and load-capacity checks of roofs for photovoltaic installations.
Supervision and review
Site supervision of structural works and review of other engineers' designs – to the same criteria we apply to our own.

An irregular oval tower and a congress centre with underground car park (B3+G+2, 70.60 × 90.0 m below ground), both cast-in-place reinforced concrete. The key issue was soil–structure interaction with the 8,444 m² excavation support, next to existing buildings and below the groundwater level. The detailed design covers formwork drawings for every floor, reinforcement drawings and special details for connections, movement joints and bearings.

Left and right bridges over a local road, the Bosna river and a main road, 12.46 m wide. Structure A is a cast-in-place post-tensioned solid slab on circular piers up to 23 m high, on caissons and piles, designed for incremental staged construction. Structure B consists of five precast prestressed T-beams on twin hexagonal piers up to 8 m high; over the main road the span is carried by post-tensioned portal frames.

Licensed software
All tools we use for analysis, modelling and drawing production are licensed.
Drawings
The drawing is what finally reaches the site. Formwork plans, reinforcement drawings, tendon layouts and shop drawings are produced by the same team that does the analysis.
Formwork plans
From the BIM model in Revit, Allplan or ProtaBIM, finished in AutoCAD, for all structure types.
Reinforcement drawings
Radimpex ArmCAD on AutoCAD and BricsCAD, ProtaDetails at the client's request, and 3D reinforcement in Allplan.
Tendon layouts
Geometry of prestressing tendons, with the stressing sequence and conditions for each construction stage.
Shop drawings
ProtaSteel, Advance Steel, Radimpex MetalStudio and Allplan Profilbauteile.
Development
iNSTRUKTA SI – Structural Intelligence. A digital chain that takes a structure from formwork plan to finished drawing, with Eurocode checks at every step.
