Arboga Mekaniska Verkstad : Förslag på saneringsåtgärder gällande gjuteriet och plåtverkstaden

Sammanfattning: The industrialization in Sweden has increased the large number of areas that have been contaminated with various types of pollution. One of those sites are the property Höjen 3:24 in Arboga where “Arboga Mekaniska Verkstad” once been. The property wants to increase the use of the old former foundry building with the adjacent “plate-workshop” and believe there are two options for the building: That the building either should be used as a warehouse/concert hall, or rebuilt into a cultural center.   An environmental evaluation has shown that the levels of heavy metals are over the Swedish environmental protection agency guidelines of less sensitive land. The purpose of this report has been to provide possible suggestions for remedial action for these two options and to describe the effects, consequences and costs of the various proposals. It appears from the report that there are two possible solutions to reduce exposure and proliferation of heavy metal pollution in the building. If the building is used for storage and concerts then the pollution should be encapsulated, while if the building is built into a cultural center, it is suggested that the pollutants are to be removed.   In an encapsulation it is suggested that the floor surfaces are reconstructed, the walls must be painted with an elastic paint and all the dust on the beams are to be vacuumed. In addition to the measures proposed is that the ground floor is dug up and the walls are milled down a few millimeters to remove the highest levels of pollutions. But there are some uncertainties and knowledge gaps in the report. It is mainly the economic aspect as calculated using prices from construction firms on the Internet and estimates on the building's size and degree of pollution. There are also gaps and uncertainties about the pollution distribution and dissemination of building materials, soil and groundwater.
