3 common errors in laying out the container yard in ICD master plan documents

When a dry port goes into operation, problems usually show up in exactly three places, and all three were decided at the planning stage, not the construction stage. Below is what we often have to rework when we receive revision dossiers.

1. Turning radius is sized for the truck, not the plot

A 40-foot tractor-trailer combination needs an outer turning radius of about 12 to 13 meters, not counting safety clearance. On drawings, intersections in the yard are easily squeezed by a few meters to gain more container stacking area. It looks tidy, but in operation drivers must reverse two or three times to get out, and each reversing maneuver costs tens of seconds, multiplied by hundreds of truck movements a day.

An inexpensive check: overlay the turning path of the longest truck combination on every intersection in the yard at the very first sketch. Where it does not fit, fix the layout, not the truck.

2. Block orientation runs against the cargo flow

Container blocks should be oriented so that the block length matches the main travel direction of the handling equipment. When blocks run perpendicular to the cargo flow, every container pick means the equipment must travel across several rows, so empty travel distance grows, and so does the number of times it crosses truck routes.

For yards operated with reach stackers, the spacing between rows and the number of rows per block determine how many rehandling moves are needed to retrieve a container underneath. That figure should be estimated when the layout is drawn, not discovered in operation when the rehandling rate turns out to be too high.

3. The inspection area is in the wrong place in the chain

The inspection area and its holding yard must sit on the trucks' natural path, not in a separate corner for the sake of a tidy layout. If trucks must leave the main route, enter a dead-end branch and come back out, every inspected consignment creates two crossings of the running traffic.

A simple rule: trace one container's path from the gate to leaving the yard, then count how many times it must cross another route. The lower that number, the better, and it can only be reduced at the planning stage.

Test your layout with one question

Before finalizing the site layout, try answering: when a container truck enters the gate at peak hour, which route does it take, where does it park, where does it turn around, which door does the cargo use to enter the warehouse and which route does it leave by? A layout that cannot answer this sequence smoothly should not yet go into the dossier submitted for appraisal.
