The Blackout Blueprint: How One Walkie Talkie Prevented a Construction Site Shutdown

The foundation was laid.
The crane was mid-lift.
And then—total darkness.

The main transformer on our urban high-rise site had blown out. No lights. No elevators. No comms.

Dozens of workers were scattered across 23 floors. Tempers flared. Radios failed. Phones? No signal inside the reinforced concrete core.

Except for one device: my CARRBORG A63.

I called the foreman on the 18th floor.
Then the electrician below ground.
Then security at the front gate.

We coordinated the entire response through a single encrypted channel. Within 15 minutes, everyone was accounted for. The emergency generator kicked in. The day was saved—and so was our project timeline.

Without the CARRBORG, we might’ve had injuries, delays, lawsuits.

Now? Every team lead gets a CARRBORG radio issued Day 1.
