FYT Engineering — Site Communication and Fleet Tracking
A construction site changes shape every week, has no fixed infrastructure and coordinates lifting operations where a misheard instruction is a safety event. TechnoRF supplies systems that deploy fast, survive the environment and move to the next project when this one ends.
Construction differs from every other sector on this site in one respect: nothing about the environment is permanent. The building changes shape weekly, the coverage picture changes with it, and at the end of the project the system moves somewhere else.
Crane and lifting coordination is the one part of site communication that is unambiguously safety-critical. A misheard instruction to a crane operator who cannot see the load is how people are injured.
The rules that hold up:
This belongs in the method statement and in the site induction, alongside the equipment.
Early in a project, handset-to-handset coverage across the plot is usually adequate. As the structure rises, reinforced concrete floors separate levels and the basement becomes unreachable; by topping out, a site that needed no infrastructure needs a repeater and possibly in-building distribution.
Planning that progression at the start — rather than reacting when the site controller can no longer reach the basement — costs almost nothing and avoids an urgent installation at the worst moment.
A contractor running several sites has a different problem: coordination between sites, plant and equipment moving between them, and management travelling. PoC over cellular covers this without infrastructure at any site, with vehicle and plant position on a map — which for plant hire management is frequently worth more than the voice service.
The common design is licensed DMR within each site and PoC across the portfolio, bridged where needed.
| Requirement | Specification |
|---|---|
| Ingress protection | IP67 minimum; IP68 where washing down |
| Mechanical | MIL-STD-810 drop and vibration testing |
| Battery | Full shift with margin; spare per radio in busy phases |
| Audio | Loud, with heavy-duty accessories for plant noise |
| Operation | Minimal controls; channel change avoidable |
Purchase suits equipment used continuously across a programme of work. Rental suits a peak phase, a single project, or a contractor testing whether radio changes how the site runs. TechnoRF supports both, with programming between projects, repair and a spares pool. Get in touch.
Rugged, sealed and simple. IP67 or better, tested to MIL-STD-810 for drop and vibration, with a battery that lasts a full shift and loud audio that cuts through plant noise. Channel switching should be avoidable — a site radio that requires a menu to be navigated will be used wrongly under pressure.
On a dedicated channel used for nothing else. Lifting coordination is safety-critical and cannot compete with routine site traffic, so the crane operator, the slinger and the signaller share a channel that carries no other conversation. Standard phrasing and confirmation of each instruction belong in the method statement, not in habit.
For a licensed system, yes, and it is worth doing. Licence-free PMR446 equipment is legal but shares channels with anyone nearby — on an urban site that frequently means hearing another contractor’s traffic and them hearing yours, which is unacceptable for lifting coordination. A licensed frequency gives a channel that is yours.
The equipment moves. That is the defining commercial fact of construction radio: the system is an asset used across successive projects rather than a fixed installation. Systems should be specified for redeployment — portable repeater mounting, reprogramming between sites, and a rental option for peak phases rather than buying for a temporary maximum.
