Building adaptation projects are prominent nowadays as there are a lot of changes in theend-user and government requirements. Within the lifecycle of these projects, the handover phase is one of the most important phase as assets and information are transferred from the project team to the end-users or operation and maintenance (O&M) team. There are two existing problems that is related to the handover phase of building adaptation projecs: (1) Different challenges are plaguing the handover phase of building adaptation projects, and (2) there is a lack of literature that study the mentioned phase. The purpose of this thesis is to address these problems by identifying potential strategies to solve the problems in the handover phase resulting to its improvement. Three data gathering methods were used. Literature review was conducted to improve the knowledge on the topic and to jump start the creation of a qualitative codebook. The next method was a review of public documents, mostly national standards, that gave idea about strategies which can be implemented about the gathered information from the first method. The third one is qualitative interview, wherein eleven (11) interview objects were asked about their thoughts on the handover phase of their building adaptation projects. Everyone had a direct experience with this type of projects. The interviews were transcribed and analysed using the qualitative software Nvivo. The data led to four (4) categories of challenges; namely, project output related, information and communication related, management related, and competency related; and different solutions which can be implemented starting from the design and planning phase of the project until the operation phase of the project output. Most of the solutions confirm what were concluded in previous studies of different authors while some bring forward additional set of ideas. The different levels of facility management also have their tasks and responsibilities in implementing these solutions. These findings will be useful for finding improvements not just in the handover phase of the project, but also in the whole project lifecycle.
