01
Welfare and effluent tanks
Empty the tank before it overflows.
A tag on each tank reports a high level and alerts the site manager and the hire company, with a record of every fill and empty.
Construction site monitoring
Construction site monitoring you reuse on every job: welfare and effluent tanks, dewatering pumps, temporary power and cabin doors report to one dashboard, which alerts the site team when anything changes.
The kit arrives as a working system: sensors that fit to temporary equipment without wiring, a ZARC Gateway in the site cabin, and a dashboard covering every site you run. When a phase finishes, the sensors come off and go to the next job.
Temporary equipment, real alerts
Construction site monitoring that moves from job to job
Tanks and welfare
High level on effluent and water tanks, so they are emptied before they overflow.
Pumps and power
Dewatering pump running and fault states, and temporary supply loss.
Temporary works
Movement records on scaffolds, props and hoardings between inspections.
Boundary and stores
Dust and noise at the boundary; cabin and store doors out of hours.
Tank levels, pump state, the temporary supply and movement on props and scaffolds are reported to the site manager as they change, with a dated log of every alert for the principal contractor.
Welfare units and their effluent tanks are the most common call-out. A tag on the tank reports when the level reaches a high point, so the tank is emptied on a schedule set by its level rather than by the calendar, and an overflow is not the first sign.
Dewatering and sump pumps keep excavations and basements dry. A contact tag reads the pump's running and fault outputs, and a power tag on its supply reports when the temporary power drops, so a flooded excavation is not discovered in the morning.
Temporary works move a little by design and more when something is wrong. A sway and movement tag on a scaffold, prop, hoarding or facade retention samples movement over time and reports average, maximum and minimum, giving the temporary works coordinator a record between inspections.
The site boundary is watched by neighbours and the local authority. Tags report dust and noise levels at the boundary through the working day, alongside the records the site already keeps.
Cabins, stores and compounds hold valuable kit. Door tags report when a store or cabin is opened outside working hours, and a sounder or alarm already on site can be brought onto the same alerts.
One ZARC Gateway on the site cabin covers the site, with its own 4G link and battery backup. When the site moves on, the tags and gateway are recovered and fitted to the next one.
02
Dewatering and temporary power
Know when the pumps stop.
Pump running and fault outputs, and loss of the temporary supply, reported the moment they change and again when they recover.
03
Temporary works
A movement record between inspections.
Sway and movement tags on scaffolds, props, hoardings, facade retention and cranes sample movement over time. It is a record, not a lifting or temporary works safety system.
04
Boundary conditions
Dust and noise at the boundary, all day.
Particulates and sound level reported at the site boundary through working hours, with alerts on limits you set.
05
Cabins and stores
Doors opened out of hours.
Door tags on cabins, stores and container doors report opening outside working hours to the site manager or security contractor.
06
One gateway per site
Moves with the job.
A ZARC Gateway on the site cabin, with its own 4G link and battery backup, covers the site. Tags and gateway are recovered and refitted when the job moves on.
Deployment approach
Start with the tanks and pumps that cause call-outs.
Most sites begin with welfare tanks and dewatering pumps, then add structures and the boundary.
We list the temporary equipment that matters on the site, fit tags without wiring, put the gateway on the site cabin, set the limits and alert routes, and test every alert before handover.
Scope
List the tanks, pumps, supplies, structures and stores that matter on the site.

FAQ
Frequently asked questions
What can be monitored on a construction site?
Welfare and effluent tank levels, dewatering pump running and fault states, temporary power on and off, cabin and store doors, movement of scaffolds, props and hoardings, and dust and noise at the site boundary.
Does it need power or a network on site?
The tags are battery-powered and need neither. One ZARC Gateway on the site cabin brings its own 4G link and keeps reporting on its internal battery if the temporary supply drops.
Can it alert before a welfare tank overflows?
Yes. A tag on the tank reports a high level and alerts the site manager and the hire company, so the tank is emptied before it overflows.
Is it a safety system for lifting or temporary works?
No. Movement readings on cranes, scaffolds and props are a record for the people responsible. They do not replace temporary works design, inspections or lifting safety systems.
Who receives the alerts?
Whoever you name for each site: the site manager, the temporary works coordinator, the hire company or a security contractor. Alerts are raised on the dashboard and sent by SMS, email or both, with escalation.
Do extra sites or alerts cost more?
There are no per-alert, per-user or licence charges. The system is charged monthly per tag and per gateway, with one gateway per site.
