House construction today is largely project-based, where the buildings are tailored tounique conditions and locations that are rarely the same as another build on anotherbuilding site. In addition to the building itself and the building site, involved actorsusually also change from project to project. As a result of today's project-basedconstruction, there is a lack of a standardized and systematic work process forconstruction work. A systematic work process could contribute to all the players' pursuitof profit. To explore the possibilities of creating an improved work process, this study focusedon balconies of wooden houses. The purpose and objectives of the work were therefore designed to evaluate today'sconstruction work for the design of balconies in wooden houses, where possible areasof improvement were evaluated to create a systematic work process for constructorsin designing and dimensioning balconies in wooden houses.In order to achieve the purpose and objectives of the work, four questions have beendeveloped that focus on the production of systematic work processes, the current workprocess of the construction work, design methods and balconies in wooden houses.Existing research and published material were found through a literature and contextstudy to further develop the study’s work. Theory regarding systematisation and process development, balconies,dimensioning of supporting structures, etc. was the basis for how the work would becarried out. The systematized work process for balcony design was, however, createdusing information from the qualitative interview study with a total of eight (8)respondents in different roles I house building. The work process was then partiallytested in a quantitative verification. The work resulted in a systematic work process in the form of a checklist that includesgeneral tips as well as a chronological workflow that describes how, when, with whomand what should and can be done at the balcony design to get the best possible results.A description of the existing balcony types has also been developed to simplify workand to clarify important points and tasks in the design of a particular type of balcony. The workflow is divided into the activities of the design and dimensioning, such asstart-up, design and dimensioning of the balcony's main components, detail designand dimensioning of fastening components, drawing up drawings and assemblydescriptions, and follow-up and development of the work process. Based on the results of the study, the questions were answered with a description ofthe four (4) types of balcony, which were based on theory and were strengthened bymeans of empirical data from the respondents. Two (2) of the balcony types are viiiconsidered more common, balconies with pillars to land and rods above the balconyplate, where the latter is considered the most common in wooden houses at present.Today's construction work for designing and dimensioning balconies in woodenhouses is similar in large part, but due to the use of prefabrication and standardizationdegree the work differs from each other. The verification of a part of the work process resulted in a balcony solution with crosslaminated timber as a balcony slab and in a comparison between results from aproposed software and hand calculations. The comparison showed that the softwarecan be used for dimensioning balconies with cross laminated timber, with the exceptionthat the dimensioning for fire must be done by hand because of deficiencies in thesoftware's settings. The study has shown that systematisation is often based on LEAN Production, whichwas created by the Japanese automotive industry, which focuses on creating efficientwork processes by circularly examining, testing, evaluating and developing workprocesses. The conclusion of the work is that it is possible to systematise construction work, butunlike the manufacturing industry, the work process must have adjustment possibilitiesduring the work to meet the commonly occurring changes in house construction.However, in order for the systematisation work to be carried out, increasedunderstanding and involvement from and by other actors than constructors arerequired. A systematic work process together with type solutions and standardized calculationmethods can shorten the design time, improve and secure the solutions, and allowmore time for creative thinking to further improve the balcony solutions and the workprocess.

Multi-story wood frame construction is a highly relevant topic today because of the need to continue to develop the relatively new building technique to create a sustainable way to keep constructing new buildings. Because the use of wood as a frame material in multi-story buildings is still new, there are still issues that come with the choice to use it. One of these issues is in the detailed technical solutions that are constructed, they often have faults that may lead to problems with moisture. The purpose of this degree project is to investigate these problems and more importantly the process behind constructing them. This work is also examining what can be done to counteract or minimize the issues in the planning phases of the construction as well as look at why it is important to continue developing wood construction. There are two parts of the method used in this degree project. The first part is a literature study which brings up the attributes of wood, factors for using and not using wood, the techniques used to build multi-story buildings in wood, as well as a look into the detailed technical solutions that are used and the planning process behind them. The second part is the interview study where experts in the field are interviewed to get answers about the issues that this work brings up. The interviews provided a lot of information that is relevant for this work and the result consists of the most important answers from them. The biggest factor for continuing to develop the use of wood as a frame material, from the interviews, was about the eco-friendliness of the material. The attitude to use wood in multi-story buildings varies quite a bit depending on which part of the construction sector is asked. The developers are curious but still a bit worried, because of this they have not yet taken the next step in using it more. The entrepreneurs are still sceptical about the use in multi-story constructions and there is not enough knowledge about it for them to earn the same amounts of money as if they were to use concrete or steel. Because of that they are also worried about taking the next step towards using wood more. The consultants, like the architects and construction engineers, are more positive to the use of wood and are inclined to use it more and more. The issues that come up the most are different types of attachments of balconies and exterior corridors, parts that are installed too close to the ground and solutions where the end grain of the wood is in water. There were three main problems that came up repeatedly. The biggest one was the lack of knowledge in the planning and the production phases. The second one was about how there is often no one who looks at the bigger picture in the projects which entails mistakes that could be caught. The last issue was in the installation where the construction workers might not do it according to the construction drawings or a lack of drawings which leads to improvisation at the construction site. Recommended improvements could be a standardisation of the solutions that are proven to work for everyone to use. There is also a need for better communication which provides feedback to the designers of the solutions, that way they will know what to do better in the future. More relevant education within the topic and better coordination will also prove vital in the continued development of multistory wooden constructions.
