Implementering av rastermått i stomprojektering av flerbostadshus : Fördelar respektive nackdelar vid implementering i befintligt ritningsunderlag

Sammanfattning: The building industry is facing big challenges in terms of producing new homes. At the same time as the cost for apartment buildings are hitting new records, an annual addition of 63 400 new homes is required to cover the housing needs. At the same time the building industry needs to reduce its emission of greenhouse gases for Sweden to reach its set climate targets. These conditions place high demands on the construction industry, and to be able to respond to the demands, it is necessary for the industry to review its way of working and develop new, more efficient methods in terms of both working methods and resource use. The purpose of the work is to investigate which advantages and disadvantages there are with the implementation of a grid dimension in the frame design when revising existing drawing documents. The goal of the work is to evaluate whether the advantages outweigh the disadvantages when it comes to the implementation of grid dimensions in the frame design. To answer the question, a literature study, a case study and an interview study are carried out. The case study is carried out at the company Fridh och Hell, and the drawing basis in which the grid measure is implemented applies to Kvarteret Barken 2, Karlstad. In the interview study, five people are interviewed who are all involved in the design work of a typical tender process at the company. The results of the study indicate that the benefits of the implementation of raster dimensions for the building's load-bearing exterior walls outweigh the disadvantages that come with the implementation. Regarding an implementation of raster dimensions for load-bearing interior walls, the conclusion is that such an implementation would be so time-consuming and extensive that the benefits achieved with it would not be sufficient justification for an actual implementation.
