Risks in small house foundations : A comparison between the risks in large civil engineering projects and small house projects (English)
Abstract [sv]

Syftet med denna uppsats är att undersöka vilka risker som finns vid grundläggning av småhus. Metoden som användes var litteraturstudie av geotekniska risker vid stora projekt. Riskerna som återkom delades in i geologiska, mänskliga och ekonomiska faktorer. Därefter diskuterades om dessa risker även är aktuella för småhus. Bland de geologiska faktorerna ansågs inte markförhållanden utgöra en betydande riskkälla för småhus då dessa antingen är välkända eller mindre svåra att kontrollera på grund av husets begränsade utbredning på marken. Däremot är det mycket viktigt att känna till eventuell förekomst och omfattning av farliga ämnen eller egenskaper i omkringliggande mark. De mänskliga faktorerna var okunskap, brist på kommunikation, otydliga kontrakt och beslut av chefer. Några risker var att nödvändiga undersökningar inte görs eller att resultaten av de undersökningar som görs misstolkas. Risker för missförstånd mellan olika yrkesgrupper ansågs vara mindre då färre människor kommunicerar på ett småhusbygge, men risken att byggherren inte tolkar experters rekommendationer rätt bedömdes vara högre. Otydliga eller obefintliga kontrakt bedömdes vara vanligare. Slutsaten var att de största riskkällorna är marken och projektledaren.

Detta är fördjupningsdelen i ett arbete som också innefattar projektering och dimensionering av ett småhus. 

Abstract [en]

The purpose of this essay is to examine the risks associated with foundations of small houses. The method used in this paper was a literature study of geotechnical risks in large projects. Recurrent risks were divided into geological, human and economic factors. Thereafter it was discussed whether these risks could occur for small projects as well. Among the geological factors, soil conditions were not considered to be a significant source of risk for a small house since these are often well known or less difficult to inspect because of the limited expansion of a house on the ground. However, it is very important to be aware of possible presence and scope of dangerous elements or properties in the surroundings. The human factors identified were lack of knowledge, lack of communication, unclear contracts and management decisions. Some of the risks implied not performing the necessary investigation or misinterpretation of the obtained results. The risk of misunderstandings between different professions was considered to be lower as there are fewer workers involved, but the risk of a client not interpreting the recommendations made by an expert was deemed to be higher. Unclear or non-existing contracts were also assessed to be more common. The conclusion was that the greatest sources of risks are the ground and the project management
