Why yards fall behind
Dock delays aren't bad luck. They're a scheduling gap.
When carriers arrive without a slot, doors pile up, trailers sit, and detention accrues invisibly. DockQueue closes the gap between the appointment book and the yard.
Blind booking
High
Carriers pick any time by phone or email — so four trailers show up for one open door at 10am.
Lost trailers
Medium
No live yard map means trailers get "found" on a walkaround — while the clock keeps running.
Invisible detention
Critical
Free-time overruns only surface on the carrier's invoice — weeks after anyone could have prevented them.
Where the 47 minutes go
Every trailer's dwell breaks down into named stages — so you can see whether the time is at the gate, waiting for a door, or on the dock.

Book · assign · track
From a booking request to a departed trailer.
DockQueue runs the whole appointment lifecycle on one board — no clipboard, no whiteboard, no guesswork about who's at which door.
Assign
On check-in, DockQueue spots the trailer to the right door — matching reefer, hazmat and load type — and logs the yard location in real time.
Track
Dwell and the detention free-time clock run live — coordinators get alerted before a trailer breaches, not after the charge lands.
Inside the product
The schedule board and the appointment file, side by side.
BuildspaceLabs built the MVP front end: a live dock-door timeline for the whole facility, and a per-appointment file for the trailer at the door.
Dock schedule board
See all 24 doors on one timeline.
A door-by-door time grid places every appointment where it belongs — inbound and outbound colour-coded, at-door and delayed flagged, with a live "now" line and yard capacity alongside.
- Dock-door timeline from 06:00 to 18:00
- Upcoming appointments with live status and dwell
- Yard capacity and on-time arrival rate at a glance
Appointment detail
Everything about one trailer at the door.
A check-in timeline from gate to departure, the trailer's contents, a dwell breakdown against target and a live detention clock — plus a one-tap door reassignment when a bay is blocking the flow.
- Gate-in → yard → door → loading → departed timeline
- Dwell breakdown vs target with a detention clock
- Recommended door reassignment to protect free time
What's in the box
Built for the dock and the yard, end to end.
Scheduling, door assignment, yard tracking and detention control on one operational surface — nothing left on a whiteboard.
Dock-door timeline
Every door as a row against the day's time axis, appointments colour-coded by inbound and outbound.
Carrier self-booking
A portal where carriers reserve inbound and outbound slots against real door capacity.
Live yard tracking
Every trailer's spot, state and dwell on a real-time yard map — no more walkarounds.
Dwell vs target
Each appointment's dwell broken into stages and measured against your target time.
Detention clock
A free-time countdown per trailer with alerts before an overrun turns into a charge.
Yard analytics
Door utilization, on-time arrival rate and detention exposure trended over time.
Dwell you can see
Detention you can prevent.
Most detention is avoidable — it comes from doors, not carriers. DockQueue shows exactly where each trailer's minutes are going, so a coordinator can act while the clock is still running.
- Every trailer's dwell attributed to a named stage.
- A live free-time clock, not a surprise invoice line.
- Door reassignments suggested before a bay blocks the flow.
