In the preservation and revitalize of historical infrastructures the informationwith which the person concerned through planning, design and/or construction of them has is very important. But as for the field of the civil engineering the materials such as drawings, photographs and written records aren't necessarily well kept. Neither specifying of the person involved in the project is not easy. So we collected the precious information of which an experienced civil engineer has by the questionnaire and tried to manage it as a database. Although we attempt to build a network of ‘advisers for cultural and historical infrastructures’who can offer some professional advice to preserve and/or revitalize the structures.
