The instinct with any bulk material is to order it all and get it out of the way. On a constrained site that converts a cheap material into a logistics problem: nowhere to put it, panels degrading outside, and a significant proportion never seen again after the first phase.
Why one large delivery goes wrong
Site storage is expensive space that other trades also want. Material delivered early tends to be moved several times before use, and every move costs labour and generates damage. Then there is the loss problem: material sitting in a communal area has a way of becoming somebody else’s solution to their own problem.
Break the order against the phase plan
Map requirement against the programme and issue call-offs around each phase, allowing enough lead time for manufacture and transport. You usually lose a little on unit price for smaller quantities and gain considerably more on handling, storage and losses. Most first-time users are surprised by the size of the difference.
Lead time realism
Manufacture is often quicker than the buyer expects and freight is often slower. Build the buffer around transport rather than production, and keep a standing call-off note you can trigger rather than starting an approval chain each time. We set out what actually moves lead times in what drives packaging lead times.
Delivery window discipline
Sites have limited crane and forklift availability and often tight vehicle access times. Book delivery slots around those constraints rather than around supplier convenience, and confirm the day before. A refused delivery because nobody could unload costs a day and a redelivery charge.
Who unloads
Establish it before the lorry arrives. Whether it is driver-assisted or site labour changes what vehicle is appropriate and how long the slot needs to be, and disputes about who unloads happen at precisely the moment everyone is busiest.
Hold a small buffer on site
A pallet of common sizes kept as a true float removes most emergency orders, which are always expensive and always urgent. One pallet is usually enough; a full stored order defeats the purpose.
Sizing the buffer
A useful buffer is the quantity that covers the most likely surprise, not every possibility. In practice that is the material for one typical area plus an allowance for the most commonly damaged size – rarely more than a single pallet, and often less.
Review the buffer at each call-off rather than letting it drift upward. Buffers grow quietly because nobody wants to be short, and pallets sitting in a corner for six months cost more than an emergency delivery would have.
What to do when it is already late
Sometimes the material is needed this week and lead time says otherwise. In that situation it is usually better to buy locally at a higher rate to cover one area than to rush a full shipment – protecting the highest risk zone buys time for the rest to arrive normally. Record why, and revisit it during the post-project review so it does not repeat.
What we can do
We hold protection panel specifications per customer so call-off orders can be placed against previous jobs without resubmitting drawings, and we will agree a standing call-off arrangement. Send your phase dates and we will plan the releases with you rather than shipping everything at once.
