The contract consists of the Ranta-Tampella bridge, Warkaanlahti bridge, Myllysaari bridge, Paasikivenkatu support wall and Paasikivenkatu road construction. The bridges cross the canal being built in Ranta-Tampella. The goal is to make the waterside area an experience and create places to stop by the water. This is an interesting bridge project in which the Ranta-Tampella bridge and Warkaanlahti bridge will share a concrete structure at the eastern end, but will fork into two bridges. The curved sides of the bridges are designed to reflect the water surface during the day, while at night they are emphasised with lighting.
The central location of the site and busy housing construction in the vicinity also require a lot from project management. The bridges are complex concrete structures, involving asymmetrical surfaces and geometric shapes that require solid expertise in concrete moulds. KFS Finland’s professionals implement anchored bored piles on the site.
The Ranta-Tampella bridges project is one of the PETOKE project pilots. PETOKE is a joint research and development project involving the Finnish Transport Infrastructure Agency, Infra Contractors Association in Finland, VTT Technical Research Centre of Finland and 19 cities. Its purpose is to develop the traditional operating models of construction projects and thereby improve project implementation and productivity. For the Ranta-Tampella bridges contract, for instance, the service providers had to undergo a rigorous preliminary process to fulfil certain requirements. During the procurement procedure, the service providers were also required to present development proposals that were innovative both technically and financially.
The customer for the Ranta-Tampella bridges was the City of Tampere, and the contract was worth approximately 3.1 million euros. The implementation time was from January 2019 to November 2019.
