Helsinki Olympic Stadium – exemplary earthworks

During years 2016-2019 Helsinki Olympic Stadium will turn into a multi-purpose venue which meets the international requirements for large events.  The Stadium will open its doors in 2019. We carried out extensive earthworks in the renewing Olympic Stadium.

This was the first phase of a thorough renovation project that is being implemented to ensure that the stadium will meet the requirements of sports federations and major event organisers.

We excavated to a depth of around 15 metres to accommodate for logistics, maintenance and training facilities. We also dismantled the sports field and excavated to accommodate for a full-length running track under the stadium.

During the earthworks phase, we were transporting around 130 truckloads of rock away from the site every day. We removed a total of 150,000 solid cubic metres of excavated rock, which the City of Helsinki is planning to use as fill when it expands residential areas towards the sea.

Working in the heart of Helsinki in the middle of a dense residential area required special attention from us. Special attention had also to be paid to traffic on the construction site because of the dense network of pedestrian and bicycle routes in the area.

“The renovated stadium will be a modern multipurpose arena that serves people even better than before. It will be able to compete for significant sports events and concerts by leading artists“, envisions Maija Innanen, Managing Director of the Stadium Foundation.

Built in 1938, the Olympic Stadium is a site protected by the National Board of Antiquities.

Our earthworks and excavation project was completed in the August 2017. During the autumn, we do reworks, and by the end of the year, our experts leave the Stadium.

"The project has been very rewarding to us. We were able to use our diverse expertise in infrastructrure construction. It was most delightful to seek and find best solutions for the renewing Olympic Stadium together with the customer", says Aleksi Laine, Director of Civil Engineering, Lemminkäinen. All in all, we removed over 20 000 truck loads of excavated rock and almost as much earth fillings and did over 2 000 blasts.
