The difference between building renovation and repair
The core difference between building renovation and maintenance lies in the nature of the project and the scope of implementation: renovation involves systematic, structural maintenance and functional upgrades, while maintenance involves localized, emergency functional repairs.
Differences in Definition and Objectives
Renovation:
Focuses on maintaining or restoring the original state of the building, including systematic projects such as structural reinforcement, functional upgrades, and preservation of architectural features.
Technical pathways must be established through suitability assessments, such as load-bearing wall reinforcement and drainage system reconstruction.
Maintenance:
Focuses on localized functional restoration, such as roof leak repairs and replacement of door and window hardware, as emergency measures.
The objective is to maintain existing functions without structural modifications.
Technical Standards and Implementation Requirements
Process Requirements:
Renovation requires specialized techniques (e.g., pressure grouting, carbon fiber reinforcement) with low tolerance for errors (e.g., bond strength ≥ 1.5 MPa).
Maintenance uses general techniques with higher error tolerances (e.g., roof leak repair error ≤ 3 mm/2 m).
Inspection and Acceptance:
Repairs require full-process monitoring, including third-party load-bearing capacity reports, seismic testing, etc.
Maintenance only requires surface functional acceptance.
Legal and Qualification Requirements
Approval Process:
Repairs involving structural modifications must be approved by the housing and urban-rural development department, and design institute drawings, structural inspection reports, etc., must be provided.
Maintenance only requires property management registration to proceed.
Qualification Threshold:
Repairs must be carried out by entities holding a “Special Engineering (Structural Reinforcement) Qualification,” and construction personnel must be certified.
Maintenance can be performed by property management teams or general contractors.
