The heritage buildings are considered an integral part of architecture in general, because of its important role in monitoring and documenting different historical stages affecting persons and reflecting on the architecture buildings to reinforce culture and concepts of the historical stage. This confirms the significant role played by accurate architectural documentation for the success of the various policies to maintain these valuable buildings, which can be maintenance, repair, improvement, rehabilitation or reconstruction, monitoring deterioration and expected risk rates. Heritage Conservation projects are divided into three main stages: “documentation, analysis and action. Therefore, the research study is concerned with documentation, monitoring and generating database stage, which results in the decision making in the next stage, where the success of those decisions depends on the efficiency of available information through comprehensive documentation. The study proposes a methodology for using the integration of modern architectural documentation techniques, which allows access to accurate and comprehensive information and data, by organizing the documentation project stages, and arrange the work out plans to clarify the accurate outputs which can be obtained in every stage, as well as expanding the use of documentation outputs and classifying the data to include a range of fields (heritage documentation - preservation and restoration - Disasters Coordination- scientific research and tourism), that are likely to benefit from such information, mostly if it is provided ,arranged and accessed from a single source, through classification and arrangement by field of use.
