Spare Parts Worth Ordering With the Units, Not After the First Failure

Spare parts are the cheapest line in a container house order and the one most often left out. The economics are simple: a part that costs a few dollars becomes a week of downtime when it has to be flown to a remote camp, and freight on a small parcel is frequently ten times the part value.

Consumables and finishes

• Sealant cartridges in the specified grade, plus a matching primer
• Touch-up paint matched to the panel and frame colours — record the colour codes with the delivery documents
• Vapour-barrier tape and foam filler
• Rivet and fastener packs in the sizes used on the unit, with the tool bits

Components that fail first

Panels and structural parts

Panel sections in the delivered thickness and core are worth a small allowance — enough to replace one damaged panel per 10 units. Corner posts and beams are rarely damaged unless something goes badly wrong during lifting, so these are usually ordered per project rather than per unit.

Tools and documentation

Ship the specific tools the assembly needs: the torque wrench, the bit sizes, the sealant gun, the panel lifting clamp. Add a printed copy of the assembly drawings, the electrical schematic and the plumbing layout, in the language the site team reads. Digital copies disappear with the person who received the email.

How to size the spare order

1. Count the installed items per unit type from the packing list
2. Apply the failure rate you are willing to tolerate over two years — 10 to 20 percent of moving parts is a reasonable start
3. Add consumables at roughly one cartridge per unit plus a margin
4. Confirm the parts are from the same batch as the fitted items, so they are interchangeable

Mark the spare parts box clearly, keep it out of the accommodation units, and record what is in it on the delivery documents. Camps that store spares in an unmarked container effectively have no spares.
