Since the early 1980s, several   research programs initiated in the construction industry with the aim of   achieving a better working environment and more codetermination in the   planning of construction projects. Integrated planning (IP) was a project   carried out in 1985-1988 as a collaboration with Lund University, companies   in the construction industry and the trade unions in the afore-mentioned   area. The integrated planning concept was developed and implemented in the   construction industry in building production. IP is a model for integrating   production planning with systematic work environment planning and integrating   the skills of all participants in building production planning from early   stage to finish. The purpose of this study is to assess the extent to which   the work environment plan is a governing document during the ongoing work   environment planning before and during construction. Work Environment Act   (AML) and its provisions (AFS 1999: 3, AFS 2001: 1 and AFS 2015: 4) are   governing for the planning of the working environment in a construction   project. Based on the provisions, the report's research questions focus on   how and at what stage a work environment plan is established, as well as how   the model integrated planning is used in the ongoing work environment   planning prior to construction start and during the production phase. Of the   companies included in the study, three of them, Skanska, Peab and NCC are   Sweden's largest company and work on a national and international scale. The   third is INAB, a small company that mainly works nationally. The results show   that work environment planning starts at an early stage with preventive   actions and routines during the building construction process and mainly   follow the same concept as the integrated planning model. Integrated work   environment planning (IWEP) is a model for building production planning that   can be used in any projects, whatever, its complexity and size. Tallåsen is a   clear example that shows the work environment plan is a governing document during   the production phase. More attention should be paid to the OSA (AFS 2015:4)   by implementing more practical preventive actio / <p>Betyg 170707, H14.</p>
