Steel Building Design and Structural Engineering

Structural calculation and construction drawings for wind, snow and seismic loads

Steel Building Design and Structural Engineering

One team solves the architectural concept, structural system choice and connection details; the drawings required for permits are prepared.

Included with a production order

The safety and economy of a steel building start with the right design. Our engineers compare portal frame, truss, lattice or light steel structural system alternatives according to the building's location, use and span requirements, and choose the most economical and safe solution.

Design scope

  • Analysis of wind, snow, seismic (TBDY 2018) and crane loads
  • Calculations of steel sections, connections and anchor plates
  • Architectural plans, sections, elevations and detail drawings
  • Layout of mechanical and electrical infrastructure
  • Structural and architectural projects required for permit and occupancy

3D model and shop drawings

The whole building is designed on a detailed 3D model, and fabrication drawings that can be fed directly to CNC machines are sent to the factory. This method minimises the risk of mismatch on site and shortens installation time.

Frequently asked questions

How long is the delivery time?
Containers take 10 – 14 working days, tiny houses 5 – 6 weeks, 60 – 120 m² prefabricated homes 6 – 10 weeks, a steel hall (500 m²) 10 weeks and a light steel villa about 14 weeks. Times may change in busy periods; the firm schedule is written in the quote.
Do prices include installation and delivery?
List prices are factory-gate building prices. Delivery and installation are quoted separately according to location. Our price calculator shows an approximate total including installation (12%) and estimated delivery.
Is a building permit required?
A building permit is required for permanent structures tied to a foundation. A time-limited permit may be enough for temporary uses such as container site offices. We provide structural and architectural design support during the permit process.
Are the buildings earthquake resilient?
All our permanent buildings are designed by structural calculation according to TBDY 2018. Light steel systems are much lighter than reinforced concrete, which reduces seismic forces. The project is adapted to the region's seismic hazard and soil class.
What is the warranty period?
A written warranty of 2 years is given for the product (facade, joinery, plumbing, paint) and 10 years for the steel load-bearing system. Warranty conditions are on the Delivery, Installation and Warranty Terms page.
