The purpose of this degree work was to compare and investigate what kind of waste that is produced on construction sites of two different types of buildings. The investigation was made to see if there were any differences between the two and how improvements with their waste management could be made. This degree work was conducted by gathering the proper information about waste and waste management, both general and specified to building waste. Information was mainly found in both papers and reports from authorities and municipalities as well as from previous degree works in the same subject. Research about which laws, regulations and requirements that are in place and relevant to this degree work was also conducted. Interviews at the two construction sites were made to see how waste management actually works on site. The research was also conducted to get first-hand information that is current to compare with previous research on the subject says. Both Västerås and Örebro municipality have their own specified waste plan that the building companies in respective municipality has to follow. The two construction sites in question differ in distance to the city centre since one is located centrally and the other approximately five kilometres from the city centre. They also differ in size of construction site, the centrally situated building site has buildings surrounding it making the space to work with small. This compared to the construction site outside of the city centre that is a part of a newer district with lots of space available. Concluded the waste management are similar to each other, with some exceptions regarding sorting of some fractions, such as glass and corrugated paper. The two constructions are built by the same company, but different recyclers are used to handle the waste. These recyclers are managing for example plaster and plasterboard differently depending on what their capabilities are. Construction sites must comply with several laws, regulations and requirements, some of them are miljöbalken, avfallsförordningen and plan- och bygglagen. Informing workers to be careful managing the materials, using more digital software in early stages and the use of production methods such as Lean are different ways to minimize the amount of building waste that occurs today. Another way is to make sure the measurements of the materials are correct from start. If so it will not be necessary to cut and adjust length and size of the material on site and thereby reduce the amount of waste.

Det här examensarbetet är ett avslutande arbete på utbildningen Högskoleingenjör Byggnadsteknik på Linköpings universitet. Examensarbetet genomfördes i samarbete med Skanska Hus i Linköping där en studie kring en ny typ av formsättningsmetod med kvarsittande form för grunddetaljer utfördes. Metoden innebar att arbetsmoment inkluderande nedtagning och rengöring som normalt ingår vid traditionell formsättning eliminerades. Företaget efterfrågade en undersökning av den nya metoden för att se om den är att föredra i kommande projekt. Rapporten inriktades på studier kring tidsvinst, ekonomisk påverkan och arbetsmiljöpåverkan. Den teoretiska referensramen behandlar förutsättningar och begrepp som ingår vid skapandet av en produktionskalkyl och hur en alternativkalkyl för val av produktionsmetod utförs. Hur exponering av damm, tunga lyft, buller, vibrationer och andra vanligt förkommande förhållanden på en byggarbetsplats påverkar yrkesarbetaren tas upp och hur de kan förebyggas genom rätt val av material och produktionsmetod. I den här studien valdes en traditionell form av plywood och virke som den metod som den nya formsättningsmetoden jämförs emot. Kalkyler upprättades för de båda metoderna och intervjuer genomfördes med inblandade parter för att bedöma hur arbetsmiljön påverkades av den nya kvarsittande plastformen. Resultatet av studien visade att den nya formsättningsmetoden innebar tidsvinster, var ekonomiskt lönsam och bidrog till förbättrad arbetsmiljö på byggarbetsplatsen.
