| Abstract: | Given the civic and social commitments of urban local bodies in developing countries, renovation and maintenance of all heritage buildings and sites is a financially non-viable proposition. Urban planners, therefore, need to take decisions on which heritage sites are to be protected (either in their original form, or with suitable modifications that permit commercial use without destroying their architectural integrity) and the sites to be pulled down, ensuring more efficient land use. Such selection can generate considerable dispute between policy makers and various stakeholders unless the selection process is transparent, consistent and incorporates views of stakeholders. The difficulty in creating an analytical framework to be used for grading is the multiple (often qualitative) attributes of heritage sites. How to combine the performances of heritage structures with respect to these attributes into an aggregative index is a major concern for urban planners and conservationists. This paper argues that the Multicriteria Decision Making (MCDM) method may be a relevant method for grading heritage sites. The application of this method is illustrated for several heritage buildings in Calcutta, India. |
