500 workers in by 7:30.Every one of them out by dusk.

Alpha manages an estate that is still being built around the families who live in it. This is how the gate learned to keep pace.

An estate that builds while people live in it

Alpha’s estate grows every week. Finished blocks are home to families, and new blocks rise beside them. The building needs hands.

More than 500 casual workers arrive each morning, most of them between 6:30 and 7:30, then a steady stream through the rest of the morning. They spread out across the sites: masons to Block C, road crews to Phase 3, steel fixers to the water tower.

Alpha started with questions, long before any talk of a system.

    1How do 500 people get through one gate in an hour?
    2Once they are in, where did each of them go?
    3By evening, did every one of them leave?
    4And if something happens on a site, where is the record?
6:30 AM

The first hour

The queue forms before the sun is fully up. The guard at the gate holds a phone running GuestPass.

On a worker’s first day, the guard records them once: name, phone, ID number, trade and a photo of the ID. From the second day on, it takes four digits.

GuestPass on the gate phone: typing 2949 in the returning-visitor search suggests ID 29496198.
Step 1 of 3
Type four digits

2949 brings up his full ID number.

Two phones, one gate

Gate A and Gate B work side by side. Each phone issues its own exit codes, so the two lines run at full speed.

The line keeps moving

Every check-in saves to the phone first and syncs as the network allows. A slow connection at 6:45 stays the network’s problem.

Every site on the list

Block C, Phase 3, the water tower: each site is a destination, so every worker is sent somewhere specific.

9:00 AM

Everyone has a place

By nine the gate is quiet and the estate is busy. Alpha opens the dashboard from the office.

Each site is a card: who arrived, who is still on it, who has left. Block C · Site 14 has eight people on it this morning. One tap lists them, each with an ID number and the minute they came through the gate.

Each site can have its own host. A site supervisor added as the host sees the same list for their site, so a short crew is visible before the foreman asks.

The count that matters

Evening is when the estate belongs to its residents again. Every worker who came in has to go out.

At the gate, the guard types an ID number, sees that worker’s open visit and checks them out. The gate phone keeps the running count on its home screen: 34 still inside, then 12, then zero.

When the shift ends with someone still on site, the list names them: who, which site, since when, and a phone number to call.

Any day

The record

Some mornings bring a question: a tool missing from Site 6, a window cracked on Block C.

Alpha searches the worker’s ID and sees every visit: the days, the site, the time in and the time out, and the gate that let them through. The answer takes seconds, and it holds up.

Visit history for Ruth Achieng on a phone: five visits from 23 to 27 September, all at Phase 3 roads, average stay 10 hours 29 minutes; Sunday 07:26 AM to 06:20 PM.

What changed at the gate

Residents sleep in an estate where everyone who came to build it has gone home.

The morning moves

The gate keeps pace with the queue, four digits and a site at a time.

Every worker has a place

Site by site, Alpha sees who is where, from anywhere.

Every evening closes

The count reaches zero, or names who remains and where.
