Things are now really rolling along in Malmö Industrial Park. The technique is calledLandpac and involves a roller compacting the groundsurface in the area section by section.Compaction ensures bearing capacity and minimises the risk of subsidence. Work on the street system will also commence later in the autumn.
It moves at about 10 kilometres an hour and with a steel roller which weighs between 8 and 12 tonnes. The compaction technique is known as Landpac, with a large roller compacting the surface of the industrial park section by section. The work, which entails compacting about 400,000 square metres, started in early September.
”This work also functions as a survey as Landpac both compacts and conducts a follow-up of the ground conditions”, explains Lars Brinte, project manager at the Real Estate Office in Malmö City Council. “It will provide us with a map of what are known as ‘soft spots’, in other words, areas where the bearing capacity has to be improved – either through doing more rolling or through adding new filling material as reinforcement.
In-depth compaction
Landpac is a fairly new technique that is faster and has greater capacity than other, similar methods. Through the steel roller, continuous impacts are generated, which compact 1-2 m thick layers, as well as having an impact at depth on filling material 3 – 5 metres down in the ground. The compaction produces the firmness and stability that will be required now that buildings and other infrastructure will soon be emerging in the area.
”The compaction work will take place over four weeks, extending into early October. There will then be a break, after which, weather permitting, the work will continue during the winter”, says Lars Brinte. Procurement of the infrastructure work that will be starting in the autumn, the street network for example, is now taking place in parallel.
Approximately 2.5 kilometres of streets are going to be constructed during 2015 and 2016. At the same time, the water and sewage system will be laid in the area, as well as the infrastructure for IT and telecoms. Lars Brinte anticipates work starting in November.
