Renovation and Reconstruction of Historical Buildings in Order to Improve Strength with Longibility: A case study of old Dhaka Central Jail

Abstract

A proper systematic approach to the restoration of historic buildings is crucial in the preservation of heritage buildings. This paper presents the unity between the restoration of a historic building and sustainability. The aim of the research is to establish an effective method for the restoration of historic buildings and their reuse and sustainable renovation in terms of energy efficiency, in accordance with modern needs and conservation requirements while maintaining the authentic appearance. Conservation Methodology is a brief appraisal of the history and development of a building or site, with an emphasis on assessing and understanding the significance of that place. The assessment of the site is based on site visits with photographic survey, basic documentary research, and a brief analysis of the surrounding arca's character and history. This assessment of significance is then used to identify any vulnerabilities within the site, as well as discussing any possible future opportunities. A combination of scientific and cultural knowledge and experience is indispensable for the study of cultural heritage buildings. The purpose of all studies, research and interventions is to safeguard the cultural and historical value of the building as a whole and structural engineering provides scientific support necessary to obtain this result. The evaluation of a building frequently requires a holistic approach considering the building as a whole rather than just the assessment of individual elements. The investigation of the structure requires an interdisciplinary approach that goes beyond simple technical considerations because historical research can discover phenomena involving structural behavior while historical questions may be answered by considering structural behavior. Knowledge of the structure requires information on its conception, on its constructional techniques, on the processes of decay and damage, on changes that have been made and finally on its present state
