Design & Technology & Evaluation

Historic preservation of modern bank architecture has common characteristics with other types of historic architectures while it shows particularity due to its unique ontology and values. Consequently, the correct method of preservation should be a combination with similarities and particularities, and also an integration of general rules and specific circumstances.Design Method, restoration technology and technology strategy evaluation are three core categories of modern bank architecture historic preservation. The relationship between them is the logic basis for demonstrating the general rules of historic preservation.Protecting mode and design skill are two aspects of modern bank architecture protection design method. The application conditions, gains and losses of the protection methods included four patterns——"old merged into new", "new melted to old", "new old apposition" and "new old insulate"——proceed from the value of the extreme protection of the modern bank buildings, and the appropriate design skills should be chosen on the basis of the architectural concrete condition and from the different angles such as space, form, order and context etc.The modern bank architecture have two basic types with contrary appearance: the modern bank architecture with intact substance and high value and the broken modern bank architecture. By means of the explain of many cases as the protection design of former Tianjin Zhejiang XingYe Bank and former Shijiazhuang PBC Head Office, the speciality of the historic protection of modern bank architecture is exactly the reflection of its value composition.The evaluation of the restoration technique strategy is the key connected the design method and the restoration techniques. The POE method such as total trace and subjective appraisals are led into the whole course of the restoration works of foremer Tianjin Jincheng bank, and verified the important value of the technique strategy POE for the pros and cons experience of the modern building historic restoration in our country. The summary of the regulation, such as nondestructive testing, the restoration technique of brick, stone and mortars, and so on, aimed at explain that the universality evaluation of the restoration techniques strategy is an effective counter measure that can control the pointers such as degree of reversibility, interference, safety and satisfaction to fit new multidisciplinary setup in the restoration techniques.
