Heritage building information modeling (HBIM) can be
considered a tool that can be utilized as an approach for
heritage buildings' maintenance plans, as maintaining these
valuable buildings, either for unexpected events or preventive
maintenance, can improve communication and integrate all of
the necessary information together. HBIM can streamline the
maintenance decision-making process by providing a digital
representation of the heritage building's characteristics and its
state of conservation, so the information can be more evident to
a decision. Because maintenance is sometimes seen as a luxury
and not a top priority in developed countries, this research
proposes a solution for putting accurate and precise
maintenance programs into practice and establishing a database
that might improve Egypt's maintenance strategy for heritage
buildings. Because they are not crucial to keeping the building
operational, mandatory maintenance activities are treated as
minor issues and dealt with in conventionally. There is
currently no convenient mechanism in place to anticipate the
effects of maintenance or to document the lessons learned from
the previous repairs, meaning that the managerial and technical
teams on every site have to start from the beginning without
being able to use previous experience data from similar cases.
The seventh pillar of BIM which related to facility management
is a strategy for managing building upkeep and improving
building efficiency by maintaining it. Additionally, BIM when
it is used on heritage buildings, it is referred to by the term
HBIM as the word heritage is being add. this can be defined as an illustrative long-term answer to the problem of performing
maintenance on heritage buildings. Old and deteriorating
buildings that need measures to keep them safe and reusable in
the face of gradual, slow deterioration, which can be termed as
a silent killer.
