Abstract: An apparatus for managing a construction site comprises a memory storing sensor data received from a plurality of capture devices associated with the construction site. The memory stores one or more rules or thresholds. A processor is configured to process the sensor data by evaluating at least one of the rules, or by comparing a prediction computed from the sensor data with at least one of the thresholds. The processor is configured, in response to evaluation of a rule, or in response to comparison of a prediction with a threshold, to trigger an alert.

Abstract: A foldable safety gate apparatus for use in relation to a hoist or lift, comprising: a main safety gate body, said main safety gate body comprising: a gate frame forming an opening; and a gate, wherein the gate frame holds said gate within the opening for preventing entry into a hoist car; a cantilever platform, said cantilever platform comprising: a supporting arm for securing to a slab; and two or more load points or securing the cantilever platform to the slab; wherein, when in a deployed state, the main safety gate body is substantially perpendicular to the cantilever platform, and, when in a collapsed state, the main safety gate body rests substantially parallel to the cantilever platform.
