Unit Times (English)

##### Abstract [en]

OBK Sverige AB is a contractor company from Örebro that was established 2011. Today they have about 65 employees. They have not been able to save as much time as they where hoping for at one of their projects called Brf Vingen. We are going to view different stages of this project and compare to another of their projects called Kv. Sjukhuset. The unit times for the different stages will be compared to the old and the new list of unit times. The purpose with this essay is to answer these following questions. • How does some of the unit times from the old list come out compared to reality? • What can be the reason that the unit times in some cases can´t be kept? • How is the new list going to come out compared to reality? The unit times for the stages will be compared to Nybyggnadslistan 1999 an not to Ombyggnadslistan 1999 because the projects which are going to be viewed are constructions and not reconstructions. These lists have been published by Byggnads, which is trade union, with Sveriges Byggindustrier. Literature studies and interviews have been used to get the information about what unit times are. Interviews have also been used to get the unit times and amounts we needed for the viewed stages.  Unit times are being used to calculate how much time it takes to build one unit of a stage. Painting, foundry work and plastering is some examples of different stages and the units can be square meter, meter, piece etc. The unit time is different for different kinds of stages. This unit time is multiplied with the total amount of the stages.  The stages which has been selected to be viewed from both of the projects are the concrete frame, the roofing and the plastering of the interior walls. The wood panel at Brf Vingen has also been selected to be viewed. The result in this essay is that the time that has been saved, using the new list, for the concrete frame at Brf Vingen has increased and at Kv. Sjukhuset it has decreased. For the roofing it has decreased, for the plastering of the interior walls it has increased and for the wood panel it has de creased.  Depending on various factors in the viewed projects the unit times in the old list comes out differently well compared to reality. The reason that the unit times in some cases can´t be kept is for example that the roof slope is too steep, small and narrow spaces and also the construction design. The new list comes out better for the viewed stages compared to reality.
