Abstract
One variation of a method for tracking lift events at a construction site includes: accessing a timeseries of load values output by a weight sensor, coupled to a crane hook, and a first geospatial location of the crane hook during a first time period; deriving a lifting profile at the first geospatial location from the timeseries of load values; deriving a weight of the object from the timeseries of load values; identifying a type of the object carried by the crane hook during the first time period based on the lifting profile; accessing a second geospatial location of the crane hook during unloading of the object from the crane hook; and generating a lift event record defining the type of the object, the weight of the object, a pickup location of the object at the first geospatial location, and a drop-off location of the object at the second geospatial location.
