An area showing signs of either active or stalled construction, at any phase – cleared ground, excavation works, foundations/slab down, frame up, or roof rafters. Residential and commercial construction is included, as is minor repair work, presence of construction vehicles, and similar visual clues to construction work.
◾️ Demolished building site (bare) with ground prepared for construction
◾️ Partially constructed building (roof not yet installed)
◾️ Part of a building being constructed (for example, roof repairs or extensions)
◾️ A completed building undergoing repairs, extensions or renovations
◾️ Presence of cranes, trucks, scaffolding, etc.
◾️ No longer a construction site when the building appears habitable, and the construction equipment is gone
◾️ Just rubble
Confidence scores can be very low in parts due to the wide range of visual appearances of construction, so careful selection of a threshold to suit the use case is important. Areas are likely to be highly dependent on threshold choice.
