This paper attempts to establish a theoretical framework for maintenance management success factors in managing built heritage. Reviews on past literature on the subject were carried out to build the existing research works on the area and to establish critical success factors of built heritage maintenance management best practices. At the end of this paper, a new area of managing heritage building for future direction of this research was identified. A list of critical success factors for maintenance management practices for heritage building was established.

Maintenance is not only important in ensuring the condition and physical of the old building to operate safely and effectively, but it also for an activity that is important in determining the life long of the building, so that it can be preserve and be inherit by the next generation. The need of maintenance is not only on repairing but more towards prevention method. According to the previous study, maintenance is done reactively; this further will cost serious problems in future. Therefore maintenance need good planning from the early stage and is followed with on-going implementation from time to time by all those who are responsible in it. In conjunction with this, this paper is to discuss about the importance of on-going maintenance in order to manage the old building after it has been gazette as heritage listed. At the end of the discussion, several strategies have been put forward in order to stimulate the practice of on-going maintenance as an initiative to encourage the culture of maintenance and also help to increase the quality process in a more effective maintenance management

This paper examines the criteria and attributes for assessing defects in a heritage building. The goal of this paper is to solve element type for building defects by using the Analytic Hierarchy Process (AHP). A survey questionnaire was develop based on the identified criteria and attributes of defect for a heritage building in Malaysia. The survey questionnaire was administered to consultants, academics, and contractors. A total of 20 expert panels was selected to determine the element of the defect in building performance. The sensitivity analysis of alternative ratings in respect to difference pairwise comparisons of the criteria and attribute was carried out. By changing one element in the pairwise comparison matrix, the process of defect element is monitored thus enabling possible improvements. An overall ranking of the Hierarchy priorities of criteria and attribute was a result of the AHP analysis. The result of the research is weightage for each criterion and its respective attributes. The criteria and attributes will be used as elements to develop a strategic heritage building performance procedure in Malaysia.

This study examines the criteria and properties of the elements in the legacy of buildings. Using the Hierarchy Analysis Method (AHP), new instruments are developed based on the criteria and attributes that have been identified for the legacy building elements. The new instrument is given to industry professionals and academicians to get their opinions. This study shows the number of attributes of the score for the criteria. The results show that new instruments are developed and used as tools for assessing the elements of heritage building conditions. This new instrument can be proposed to the National Heritage Department to be used as a guideline for assessing the heritage buildings in the future.

Assessment of buildings is one of the main components that are essential to assess the condition of the building. Without evaluation, it is difficult to determine the current condition of a heritage building, so failure to check can contribute to future assets. The objective of this study is to assess the level of defect condition in a heritage building. This study has selected nine buildings of the museum as a place of study. The location of the museum building is located in three states of Kelantan, Terengganu, and Pahang. All of the museum buildings have been implemented by using Building Defect Assessment (BDA) and used as a survey tool to assess the level of disability at museum building. Defects of each element in the building of the museum have been recorded.  As a result of the BDA suggests that score full points used to provide the level of evaluating the overall condition of the museum building is good, and the need for action to maintenance requirements such as monitoring, repair, a replacement for preventing defects or serious damage.
