Prestressed structural design services

Sweco is the market leader in prestressed structural design in Finland. We deliver cost-effective, construction-friendly, and low-carbon post-tensioned structural designs by leveraging our strong BIM expertise and the best modeling and design tools available.

Post-tensioning is a unique method to enhance the capacity and performance of cast-in-place concrete structures.

Prestressing enables watertight, crack-free, and monolithic concrete structures, providing a long service life with minimal maintenance needs. It also allows for more complex and spacious architectural designs, longer spans, and thinner load-bearing structures.

We design prestressed structures for a wide range of projects, including shopping centers, office buildings, parking facilities, deck parking structures, and industrial sites—from nuclear power plant structures to various types of tanks. Post-tensioned cast-in-place structures are also commonly used as load transfer structures.

Prestressed structures are more environmentally friendly, as the reduced amount of concrete results in a smaller carbon footprint.
