The thesis has been made for NCC Teknik in Gothenburg. The NCC Corporation is one of the largest leading companies in Scandinavia within the construction industry. NCC is active throughout the whole construction process, where one part is to carry out soil investigations prior the construction of various buildings, for example residential buildings. NCC Technology wants to visualize the samples taken at the construction sites in 3D for clients, authorities and also internally to show in a simple and understandable way how contamination is spread out in the soil. The thesis includes the area of Limhamns läge in Malmö, previously an industrial area. The area has previously included a concrete factory and the contamination from that factory has lingered in the soil. Here, the old buildings will be demolished and will be replaced by residential area and parkland. The contaminated soil must first be transported away to enable people to inhabit in the area. The goal has been to develop a method that improves visualization of the soil remediation process by creating 3D models that could replace the visualization in 2D and tables with analysis results. The idea is that the method of 3D visualization can be applied to other soil remediation processes and some shafting. Limhamns läge has the been divided into the squares to be able to take samples, which in turn are divided into boxes in depth which is defined as 20x20x0,5m. After the samples have been analyzed it is possible to determine which boxes that can remain in place, which ones that can be reused in the area and which ones that need to be transported away for landfill. The created models are visualizations in 3D showing the distribution of soil contamination. One model is divided into half meter layers, making it possible to see the various levels of contaminants in the soil. A 3D model has also been created where the uncontaminated boxes have been separated from the other boxes and it allows visualization of the contaminated boxes. A model has been created that shows how the shafting work progresses by gradually remove boxes that have been shafted for each week. The models are designed to capture the results of analyzes by sieving. They are divided for each fraction, coarse, medium and fine. The models show what material can be reused and what should be transported to the landfill. The second version of the model shows the proportion of each fraction that was found in the sieved boxes.
