Abstract
In this thesis I study the wasted time in electrical and HVAC work to create possibilities for improvements for sub- and main contractors. To goal is to find out the share of wasted time and it’s root causes. This thesis studies the share of the value adding, value supporting and non-value-adding actions in Finnish construction. This thesis aims to find out problems in Finnish construction industry by tracking and interviewing workers and the foremen of the working crews. The tracking of the working was being done via helmet cameras and this data was being used also in the interviews to get better insight on different causes for problems and repercussions of these problems. The helmet cameras provide both qualitative and quantitative data, which gives insight to the wasted time and problems that occur. This thesis tracks and interviews workers from four different construction sites to provide vast information. This thesis study uses the workers point of view, as this might often get ignored. By tracking and interviewing the workers, the workers have possibility to point out im-provement suggestions to enhance their work. In overall this study’s goal is to find out the share of wasted time and its reasons. This study brings out the workers improvement suggestions, but the final improvements should start from the sub- and main contractors actions. The final thesis offers the share of wasted time and it’s reasons with vast categorization, which allows focused improvements to be made to decrease the amount of wasted time by preventing the reasons behind them.Description
