#1. Pre-demolition condition surveys
A dated photographic and video record of the site — and critically, of neighbouring structures and boundary walls — taken immediately before mobilisation is the single most valuable piece of documentation on a demolition project. It's the reference point for resolving any later claim that the demolition works caused damage that, in reality, predated them.
#2. Drone and aerial survey
Drone footage gives a full-site overview that ground-level photography can't — useful for larger sites, industrial plots, or projects where rooftop and upper-level conditions need recording before work starts. It's also increasingly used during the works themselves to document progress objectively, without relying solely on the contractor's own written progress reports.
#3. 3D laser scanning
For larger, more complex, or higher-value structures, full 3D laser scanning creates a detailed digital record of the building before demolition — useful where a structure's exact dimensions or condition may later matter for insurance, dispute resolution, or even future redevelopment planning on the same plot. It's a higher-cost step than standard photography, so it's typically reserved for projects where the scale or complexity justifies it.
- Dated, timestamped photo and video record before mobilisation
- Specific documentation of neighbouring structures and shared boundary walls
- Drone survey for full-site or rooftop conditions
- 3D laser scanning for larger or higher-value structures where detailed records matter
- Progress documentation through the works, not just before and after
#4. What this actually protects against
Good documentation protects the demolition contractor from unfounded damage claims, protects the property owner if a dispute arises with a neighbour or insurer, and gives consultants an objective record for sign-off rather than relying on site diary entries alone. On insured projects, insurers increasingly expect this kind of record as standard practice, not an unusual client request.
