Abstract [en]

This Bachelor thesisis  a  comparison  of  two  different  concrete  forms  viewed  from  a sustainable perspective by using a Multi Criteria Decision Making(MCDM)method. Sustainability  is  a  broad  concept,  often  degraded  in threepartswhich  are  financial-,environmental-and  socialsustainability. This Bachelor thesisstrives  to  determine what sustainability is when it comes to monolithic concrete casting in Sweden. In this Bachelor thesissustainabilityhas   been   degraded   in threeparts,   financial-,environmental-and work environmental sustainability.Although,the  two  different  forms  fill  the  same  function,  they  differ  in  many  areas. The first one, TRIO,is made of steel and plywoodand is heavy, loud, with a big area and in need of a crane to be able toassemblethe form. The second one, DUO,is made from the composite  materialPolytech  and  isalmost  soundless,  with  a  smaller  area and lightweight tobe able to be used without crane.    The purpose of the MCDM-methodis to create a tool with the purpose of facilitating the  choice  of  concrete  forms  for  monolithic  casting  while  taking  sustainability  into account.   The   tool   is   to   ease   the   decision   in   building   production   for   both  the contractor and for designers. The Bachelor thesisis a case study with both qualitative and quantitative methods.To make  a  fair  comparison  between  the  two forms  in  this Bachelor thesis,a  fictitious project  is  created toevaluate  different  criteria  for  sustainability  in  design  and production. This is doneunder the same premises to be able to obtain an equivalent result.In the fictitious project it turned out that TRIO was the best choice from work environment and economic sustainability, from environmental sustainability it turned out that DUO was the best. Furthermore, it has been difficult to obtain full validity in the MCDM method, all criteria have not been fulfilled inthe environmental field. The environmental area has been the most difficult to investigate and to obtain relevant data in.MCDM has good opportunities to provide great benefit if there were more standardized data to put into it. In this work, very much work was done for a small result.
