Ulma Construction
ULMA’s solutions in one of the biggest structural challenges recently undertaken in Portugal
The extension of the Colombo Shopping Centre in Lisbon comprises an office building of approximately 35,000 m² and 4,000 tonnes of steel, supported by a structure reminiscent of bridge engineering.

The adopted solution is as innovative as it is functional: nine large-span steel arches, each weighing approximately 150 tonnes, support nine suspended slabs and distribute loads through just twelve columns. This design frees up interior space, creating an open, flexible and highly versatile floor layout.
ULMA played a key role by designing and supplying more than 400 tonnes of bespoke formwork and shoring for one of the most singular structural projects in the country. Close coordination between ULMA’s technical team and the site ensured deadlines were met and technical challenges successfully overcome during assembly.
