What work does the maintenance engineering design of ancient buildings include?

Engineering design should be carried out before the maintenance of ancient buildings. Engineering design includes two parts: determining the engineering scheme and formulating the design documents. The engineering design scheme should first abide by the principle of not changing the original state of cultural relics. On the basis of investigation and study, a scientific and comprehensive analysis should be made according to the causes and present situation of damaged buildings, and a reasonable and feasible maintenance and reinforcement scheme should be designed in combination with technical conditions, economic conditions, construction conditions and material supply, and then a specific technical design should be carried out. Design documents mainly include design drawings, practice notes and project budget.

Major repairs and partial repairs shall be designed with a scheme, including the actual measurement and repair design scheme, survey report, repair summary and budget summary. Technical design includes technical design drawings and construction details, technical design and construction instructions, design budget, current situation photos, and material test reports when necessary. For the repair and reinforcement project of cave temples, engineering geological data and exploration reports should also be submitted, and if necessary, inspection reports on chemical reinforcement and windproof treatment should also be submitted.

If the key repair project belongs to the status quo maintenance, it can be designed once, and the following design documents are put forward: the status quo measured map, technical design and construction drawing; Investigation report and material test report; Technical design and construction instructions; Design budget; Photos of damage and architectural features.
