The concept of building work environment co- ordinator is a relatively new concept that has its origin in the amendment to the Working Environment Act which came into force on 1 January 2009. The terms; building work environment co-ordinator appointed for planning and design and building work environment co-ordinator for the execution of building or civil engineering work ushered in the industry. Once these disciplines complement one another, you can achieve a smooth handover to ensure a good and healthy working environment. In this thesis, we study a company in Uppsala and their operations and handover by interviewing the relevant staff in question. The result shows that there are currently no present guidelines for how and when the handover should take place, it is up to each individual to provide themselves with the relevant information. If the handover of the work environment would occur to the extent it should it would lead to minimized proportions of unforeseen risks and events that may occur during the production phase, which ultimately leads to a better and healthier working environment.
