A safety system for construction workers comprises beacons, a safety harness and a safe anchoring location. The beacons are placed to define a danger area on a construction site. The safety harness to be worn by a construction worker is equipped with sensors; and the safe anchoring location anchors the safety harness. The safety system is able to issue an anchoring requirement for the harness to be anchored to the safe anchor location, say as an audible warning, when the harness is detected by the beacons to be within the danger area.

A hoist elevator control system and a hoist elevator for a multi-story building structure on a building site, comprises an enclosure for raising and lowering personnel and materials. The control system comprises a sensor external to the enclosure, a sensor internal to the enclosure, a call button at each floor, and a processor located within the enclosure. The processor obtains data from the sensors and the call buttons and provides output to a display screen in the enclosure and to an external control location. The internal sensor may be a people counter that issues an alarm to prevent operation when the enclosure has more than a preset number of people within. The people counter may send the current number of people within to the processor for processing, and data may allow an operator to control the elevator, for example via a cloud connection and/or a telephone application.
