Use Cases · Case Study
A construction site never looks the same two months in a row — new zones open, crews rotate, and hazards move with the work. Here’s how four Collie modules combine into one system that keeps pace with a site that’s constantly changing.
The Site
A construction site is never finished being built — literally. Zones open and close as work progresses, several contractors rotate through on different schedules, and heavy machinery shares ground with workers on foot. Fixed infrastructure struggles to keep up with a layout that’s different every few weeks.
This is the profile Collie is built for: not a single problem to solve, but several running in parallel, on the same site, at the same time.
The challenge
A helmet or vest checked at the gate says nothing about whether it stayed on for the rest of the shift, across a rotating workforce.
With multiple contractors on different schedules, knowing exactly who’s present at any moment — for safety or for payroll — was mostly guesswork.
Unstable structures and hazardous zones needed to stay empty overnight and on non-working days, but nothing was actively watching them.
What’s inside
Three capabilities that apply across all three user types, each configured to fit the population.
Cameras across active work zones flag a missing helmet or vest in real time, with compliance trends by zone and shift, not just a gate check.
Beacons on worker passes put every crew on a live floor plan, with a movement history for both safety and rescue & recovery scenarios.
Workers, staff, and visitors are registered as distinct types, each with their own access rules that expire when the assignment or visit ends.
Unfinished and hazardous zones are flagged as restricted, with detection running around the clock or only outside working hours.
How it comes together
The same loop that runs across all of Collie, applied to one construction site.
Cameras and worker beacons report continuously — PPE status, worker positions, and who’s just entered a restricted zone.
Each module applies its own rules — a missing helmet, an expired visitor pass, a human presence after hours.
Alerts reach the right supervisor immediately, and everything — from every module — lands in one dashboard instead of four.
What changes
Not a single big number — a set of daily improvements that add up across a rotating workforce.
PPE
Helmet and vest violations show up live, with trend data by zone and shift.
Workers
Knowing exactly who’s on site stops being a guess, even with multiple contractors rotating through.
访客
Visitor and short-term worker access ends automatically when the assignment does — no manual clean-up.
安全
Restricted and hazardous areas get flagged the moment someone’s there, day or night.
Knowing exactly who’s on site stops being a guess, even with multiple contractors rotating through.
Where robots fit
A Collie robot can carry PPE detection, worker tracking, and restricted-zone monitoring through areas that don’t have fixed cameras yet — useful for a site where next month’s layout doesn’t exist today.
