The Swedish building contractor JM Region Öst would like to to investigate the possibilities of developing and streamlining the production of singlefamily houses. JM are producing singlefamily houses with prefabricated frames at a rate of about two houses per week. During construction, the different tasks are performed by JM’s own production staff but also by various subcontractors. When examining the schedules of recently produced projects, it appears that all the houses are more or less completed eight weeks before the customer moves in to the house. During those eight weeks several operations are conducted such as inspections, installation of appliances and cleaning procedures. The inspection period constitutes between 25 and 35% of the complete construction period. By conducting interviews, it has been discovered that this final phase is an essential security buffer for delays and errors that often occur. Reducing the time needed for inspection requires that all activities are properly conducted with the right quality from start. After analyzing the results of the interviews and the comparison of project schedules, the following conclusions have been made: • The time required for inspections at the end of each project can be reduced if at the same time quality inspections and management of subcontractors are improved during the whole of the construction period. • The construction rate is difficult to increase as it is depending on the supply capacity from the house supplier. • The experience feedback at JM can be improved, mainly through feedback to the production staff at the beginning of new projects
