PURPOSE OF DILAPIDATION SURVEY
Construction, especially excavation and drainage may affect the stability of surrounding structures. Dilapidation survey is carried out to record the status and damage of adjacent buildings before construction. It is also the document as a basis to evaluate the effects caused by the construction process.
METHOD OF DILAPIDATION SURVEY
All adjacent buildings within the influence range of construction work must be surveyed. Survey content includes:
- Measuring geometric dimensions of adjacent buildings.
- Surveying of structural characteristics of adjacent buildings.
- Determining the tilt of adjacent buildings.
- Recording cracks by taking photos.
- Measuring the length and width of the crack.
- Identifying materials used for the project.
- Recognizing the current status of architectural structures: Frame, column, ground, wall, door, …
After completing survey work of each building, making a record of the witness of the landlord or the representative of the landlord, this report will be attached to the survey results report.
