A scaffold yard should be laid out so material is easy to reach, inspected for damage before it leaves, and tracked in and out. NASC SG40:20 covers yard operations, and a set of technical guidance notes covers boards, couplers, tube racks and nailplates. This page maps each document to the job it helps with.

This is our practice, not a quote from the article.
- Receive. Count against the delivery note and record a goods received note.
- Inspect. Reject bent tube, damaged boards and unmarked couplers.
- Sort and store by item and condition, with clear pathways and signs.
- Issue against a written request with the tag or job number.
- Return. Count, inspect, and separate repair, scrap and return-to-stock.
- Reconcile weekly. Opening stock + received - issued + returned = closing stock.
What the article says that is worth copying
It says equipment should be inspected for damage before it leaves the yard, with clear pathways, signage and inventory tracking. One yard manager is quoted as unloading 6 to 8 trailers a day and says the systems made unloading 8 times quicker: this is one person's account, not a benchmark. The same text says the auditor visits the yard over 20 times a year.
Common mistakes on site
- Storing boards and tube mixed, so damage is found only at the work front.
- Issuing without a request number, so returns cannot be matched (see loss and damage after a shutdown).
- Skipping the return inspection because the shutdown is busy.
