The Kruunuvuori Bridge will be built by the Crown Bridges consortium, which consists of Kreate Oy and YIT Suomi Oy. Sepa and Kreate have collaborated on several similar, albeit smaller, projects. On that basis, it was also natural to start the construction of the Kruunuvuori Bridge.
For Sepa, we were on the verge of a unique project – a construction site bridge delivery of this size has never been carried out in Finland before, and the size and schedule of the project were also record-breaking. Sepa built a special machine line at the factory to ensure the required production capacity.
Construction site bridges quickly completed
Kreate’s Site Manager Mika Huhtala was involved in the construction of the substructures of the Kruunuvuori Bridge. The size of the project is indicated by the fact that while bridge construction projects are typically completed within a year, the subsurface phase alone now lasted a year and a half.
Due to the demanding bridge structure, the project began with the intensive construction of two construction site bridges. For these construction site bridges, Sepa supplied beam elements for these temporary bridges. Mika Huhtala says that Sepa has performed its demanding part of the project flawlessly.
“Goods were delivered efficiently since the bridge was constructed five days a week, day and night. In three months, we built 650 metres of work bridge at sea, as well as so-called bays around the intermediate supports, where pipes could be up to 40 metres long.”
Huhtala praises the logistics for working well with Sepa. Goods arrived at the construction site exactly when they were supposed to, so that the work proceeded smoothly without unexpected surprises or waits.
“When working below sea level, surprises happen more often, but now we managed without anything bigger. With Sepa, everything went smoothly. They responded to requests whenever it was needed, and they handled everything well.”
