Facilities Management (FM) is one of the essential aspects that needs to be considered in the building maintenance management plan. Generally, the scope of FM involves thorough and effective administration, finance, operation and maintenance of the building. In the context of the Private Finance Initiative (PFI) projects, the operation and maintenance stage is longer compared to the design and construction stages. Therefore, the focus during this stage should be emphasised proactively. This research aims to determine the significance of FM aspect towards maintenance management plan of PFI projects during pre-development stages. This research used previous literature, mainly from journals articles to construct the models and formulate the literature reviews. Additionally, a quantitative approach was employed as the research methodology. A questionnaire survey was distributed to the maintenance personnel involved in the PFI projects in Malaysia. The survey was conducted towards the educational PFI projects only. This research also used Partial Least Square-Structural Equation Modelling (PLS-SEM) software to perform data analysis. There are two constructs in this research which are the FM aspects and maintenance management plan. The measurement and structural models were developed to determine the significance of the FM aspect towards the maintenance management plans. There are five indicators that represents FM aspects and six indicators of maintenance management plan highlighted in this research. All these indicators are proven to be reliable and valid through the internal consistency, convergent validity, cross loading value. The Fornell Lacker Criterion was conducted to prove discriminant validity between FM aspect and maintenance management plan. The findings of this research found that the FM aspects are very significant towards the maintenance management plan of the PFI project during the predevelopment stages. It was proven through structural model analysis using p and t-value. This research can be beneficial for better implementation of maintenance management.
