BYGGHERRENS FÖRSTA SMÅHUS - fel, ändringar och tillägg i byggskedet

Sammanfattning: The report is a degree project in the program Construction Technology with a focus onhouses. It is about errors, changes and additional work regarding construction of smallhouses. The developer is usually a novice in the field and does not have experience inmaking decisions in the design stage. Changes and additions will then occur in varyingdegrees during the construction phase instead. This leads to unnecessary time-wasteand a higher cost. Therefore, further examination in the area is valuable to identify themost frequent change and supplementary work. This knowledge can then be used toprevent these changes from happening through purposeful planning.The methods of the survey were surveys for core stakeholders, search of archives witha review of the controller's (KA)-documentation to final consultation protocols and areview of requirement analysis through house suppliers with links to literature. Therequirement analysis with the literature review was done by contacting various housesuppliers. The house suppliers also answered questions and returned various documentssuch as quote templates.The core stakeholders who were investigated in this work include architects, builders,contractors, inspectors, control managers according to plan and the Building Act (PBL2101: 900) and house suppliers. The contractors have professions such as carpenters,excavators and project managers.The result showed both in the surveys and in the protocols (KA) that the most commonconstruction fault, changes and additions apply to installations and specificallyimplementations of various kinds. The reviews are for example pipes that go throughthe base plate or fire -rated wall.Surveys and final council protocols (KA) were analysed by being read several times.First, they were read through in order to create an overview and then in search foranswers to a specific question. Collected data was divided into different categories andcompiled. Categories are land and foundation, frame, installations, facade and ceiling,and other.The interviews with the requirement analysis as well as the documents from the housesuppliers were read through and an analysis was carried and compiled.The respondents believed that an area contained the most commonly occurring errorsand additions, but the survey and protocols (KA) showed something different. Oneinterpretation is that since an unconsciousness exists about the fact that sealing aroundimplementation is common work that has been missed, it therefore is precisely thereason why it has been missed. Number of errors with penetrations could be dependenton that there are several different contractors who need to cooperate with transitionsbetween different materials.The process between a salesperson working for house suppliers and the customer has abig impact for the occurrence of future changes or additional work.Keywords: Housing, construction failure, builder, inexperienced builder, additionalwork, changes.
