The night queue at the gate: a playbook for sites that run three shifts.
A queue at the gate at night is rarely a gate problem. It means nobody upstream told Security who was coming.

A queue at the gate at night is rarely a gate problem. It means nobody upstream told Security who was coming.
The visit was arranged in five inboxes. Security has a paper register and no list of who to expect, so every arrival means phone calls to hosts, often after hours, while vehicles wait.
| Measure | Target direction |
|---|---|
| Arrivals not on the expect list | Down |
| Calls from the gate to hosts | Down |
| Time from booth to room | Down |
| Visits with complete hand-off record | Up |
Sampark is a site-operations control tower for mines, plants, townships and camps. A request arrives by email, form or WhatsApp; AI reads it once and pulls out guests, dates, rooms, travel, transport, access and host, and a person checks it. Rooms, travel, transport, safety and gate each approve their part of the same request. The guest goes onto the gate’s digital expect list with a QR before the vehicle reaches the booth; at check-in the host and room are alerted and housekeeping is warned 15–20 minutes out. Checkout opens the cleaning job and the live room board flips to free when it is done. Every approval and hand-off is visible to the head of admin from a 24×7 control tower, on web and WhatsApp.
Usually because Security has no advance list of expected visitors, so each arrival needs phone calls to the host before entry.
The approved visitor receives a QR in advance; the gate scans it, matches the visitor’s ID against the digital expect list and alerts the host.
