We performed civil engineering, concrete and water supply and sewerage works for the new Tahkoluoto port unit processing bulk materials. The project’s client is the leading port operator and largest port bulk operator in Finland. The goal was to raise the capacity and efficiency of the bulk port in Tahkoluoto, Pori, by automating the processing of bulk materials.
Due to challenging site conditions, the contract demanded expertise and experience on working at operated port areas. Furthermore, expertise was required for working in the vicinity of an operational railway, below groundwater and rock excavation near the supporting wall of the excavation.
We utilised model-based production and work machine automation in the contract work. The contract covered a large area, and we were able to limit traditional measuring work through the use of machine automation.
We constructed the concrete structures required by the equipment that processes the bulk material coming in by the railway tracks, the water supply and sewerage system for the area, the underground protective pipes for the electrical systems and manholes, roads and bulk material storage base structures along with the supporting walls. We cast the facilities’ massive concrete structures, the tallest of which were 14 metres tall.
The project also included a set of specialised structures. For example, we cast a new 220-metre-long rail beam along with the rails for the dock crane, in an area where the loading of ships could not be disturbed. In addition, we built the terminal’s underground concrete structures for the railway wagon handling in a waterproof 15-metre-deep excavation supported by 400-millimetre bored piles. We also cast a 60-metre-long underground transport tunnel. The deepest installation we performed was for railway turntable concrete structures 12 metres below groundwater.
The anchoring for the supporting walls was performed on 2–3 levels, and a total of 114 anchor points were required. We also performed pressure grouting for the supporting wall bases and pile locks and poured concrete for the bored piles to ensure that the excavation stays waterproof.
