Built on the job site

This started on a downtown high-rise. Dozens of deliveries a day, one narrow street, and a crane schedule that had to line up with everything else. Forklifts needed to be available when the truck arrived. The crane had to be free to make the pick. The loading zone had to be clear before any of it could happen. One missed detail and three trades are standing around while a flatbed blocks traffic.

We built spreadsheets. Good ones, actually — color-coded, time-blocked, shared with the team. But keeping them accurate was a job in itself. Every change meant updating multiple tabs, notifying multiple people, and hoping nobody was looking at the old version. And no matter how well they were built, they couldn't reliably stop two deliveries from being scheduled for the same dock at the same time, and all along the way it never really felt like any of it was saving any time or energy.

We looked for software. There's plenty of scheduling tools out there, but they're designed to schedule people — meetings, shifts, appointments. They don't understand that a crane is a resource with a capacity of one. That a loading zone isn't a conference room.

So we built what we actually needed. GateKeeper lets you schedule deliveries, cranes, forklifts — any site resource — into defined zones and time slots. Vendors book themselves through a link. Conflicts are detected automatically. You see the full picture on one calendar and approve with a tap. No phone calls, no spreadsheet maintenance, no surprises at the gate.

It's deliberately simple. It runs on your phone because that's what you've got in the field. And it does one thing well instead of fifty things halfway.
