Inbound and outbound halves of one Eastern Creek distribution shed

Pallets that have travelled by road carry grit, water, timber splinters and whatever was on the trailer floor. When the wrap comes off at the receiving point, all of it lands in a concentrated area, along with film, dunnage and broken pallet timber. That is a heavier and coarser soil than anything the rest of the building produces, and it responds to sweeping and mechanical removal rather than to detailing.

It is also predictable in location. The unwrap point, the first few metres of the receiving lane and the area beside the pallet stack account for most of it. Scoping those specifically, at a frequency matched to inbound volume, deals with the problem where it occurs. Spreading the same effort evenly across the receiving hall costs more and achieves less than concentrating it where the debris lands.

Despatch generates film offcuts, label backing, tape ends, strapping and carton fragments. Individually they are trivial; collectively they migrate across a shed on air movement and end up against walls, under racking and in the dock area. They also cause practical problems: film wraps around wheels and brushes, and label backing sticks to a wet floor and lifts again later. Strapping is the worst of them, because a loose band on a floor is both debris and a trip hazard.

The method that suits is frequent light removal rather than periodic deep work. A short pass through the despatch lanes at the end of each shift removes the material while it is still where it was dropped. Once it has migrated, the same volume takes several times as long to collect. That argues for frequency over intensity in this half of the building, which is the opposite of what inbound usually needs.

Inbound is usually busiest early and quiet later. Outbound builds through the day towards a cut-off and empties after it. The consequence is that each half has a genuine window, but the windows are at different times, and a single attendance scheduled for the convenience of a roster will hit one badly. Sites often describe themselves as busy all day when what they mean is busy at both ends for different reasons.

Splitting the attendance is often cheaper than it sounds, because each half needs less time than the whole. Where a split is not practical, the scope should name which half is prioritised and what the other receives, rather than promising both and delivering an average. The site can then decide which end of the building matters more, which is a decision it is better placed to make than a contractor is. A stated priority also gives the crew something to follow when a shift overruns.
