A supervisory system is a typical feature of an anti-collision system that covers an entire construction site. It allows a site supervisor to have a complete view of tower crane operations on a construction site. It also allows for centralised configuration and maintenance of the system. [2]
Automatic deformation monitoring device at a construction site of Porto Metro [15]. Deformation monitoring can be manual or automatic. Manual deformation monitoring is the operation of sensors or instruments by hand or manual downloading of collected data from deformation monitoring instruments.
A falling weight deflectometer (FWD) is a testing device used by civil engineers to evaluate the physical properties of pavement in highways, local roads, airport pavements, harbor areas, railway tracks and elsewhere. The data acquired from FWDs is primarily used to estimate pavement structural capacity, to facilitate overlay design or ...
An interlock device is designed to allow a generator to provide backup power in such a way that it (a) prevents main and generator power to be connected at the same time, and (b) allows circuit breakers to operate normally without interference in the event of an overload condition. Most interlock devices for electrical systems employ a ...
Automation in construction is the combination of methods, processes, and systems that allow for greater machine autonomy in construction activities. Construction automation may have multiple goals, including but not limited to, reducing jobsite injuries, decreasing activity completion times, and assisting with quality control and quality assurance.

Construction field computing is the use of handheld devices that augment the construction superintendent's ability to manage the operations on a construction site. These information appliances (IA) must be portable devices which can be carried or worn by the user, and have computational and connectivity capacity to perform the tasks of communication management.
A ratchet (occasionally spelled rachet) is a mechanical device that allows continuous linear or rotary motion in only one direction while preventing motion in the opposite direction. Ratchets are widely used in machinery and tools.
Lifting equipment, also known as lifting gear, is a general term for any equipment that can be used to lift and lower loads. [1] Types of lifting equipment include heavy machinery such as the patient lift , overhead cranes , forklifts , jacks , building cradles, and passenger lifts, and can also include smaller accessories such as chains ...
