We Offer:


Reduced construction costs


Reduced construction time


Increased profit


Reduced unforeseen costs

Structural Engineering - 5D

We are one of the very first companies in BIM strucutural engineering and have completed more than a dozen different BIM projects in the Nordic countries.

Descon ensures optimal and efficient structural design solutions for unique projects. We are implementing BIM technologies and solutions throughout the design cycle from concept, resource planning, price calculation to manufacturing and construction processes.

What opportunities offers BIM technology to optimize building design?


  • BIM modelling;
  • Structural calculation and optimization, engineering technical consultancy;
  • Structural engineering (precast, steel, wooden structures);
  • Structural steel detailing and fabrication drawings
  • Precast detailing and fabrication drawings

BIM project management

For the implementation of projects DESCON uses The Royal Institute of British Architects model for the building design and construction – The RIBA Plan of Work. 

The RIBA Plan of Work organises the process of briefing, designing, constructing, maintaining, operating and using building projects into eight Work Stages.

Preparation and Concept design stages are crucial for the savings of costs of the project.
