Current Lot Review

Current Lot Review compares proposed natural-stone evidence with the project's written brief. It can organize lot identity, slab or piece images, dimensions, finish, visible variation, repairs, documentation and quantity. It does not perform a physical inspection, laboratory test or engineering approval unless a separate qualified provider is explicitly appointed and documented.

Tie evidence to the proposed lot

Record the supplier, material name, quarry or origin where available, block or lot identifier, date, quantity and proposed pieces. Images should be mapped to identifiable slabs or packages rather than presented as generic marketing references. If physical samples or inspection reports exist, link them to the same identity and note whether they represent the full lot or only a subset.

Compare against written acceptance criteria

Review background, movement, inclusions, pores, fissures, repairs, resin, mesh, reinforcement, finish, thickness, dimensions and yield requirements that are visible or documented. The review should separate observations from judgments and identify what cannot be assessed remotely. Any required technical property must be supported by applicable evidence rather than inferred from a material name or photograph.

Close outstanding items before release

List unresolved questions, deviations and approvals, then identify who can accept them. Confirm fabrication scope, layout, sample standard, inspection, marking, packing, loading, quantity, destination and replacement strategy. A lot should not be described as approved merely because images were received; the project team must record its decision and the evidence it relied on.

Written confirmation

What to include in the next brief.

  1. Record supplier, material, origin, block or lot, piece identity, date and proposed quantity.
  2. Map current images, samples and documents to identifiable material and acceptance criteria.
  3. List visible variation, repairs, treatments, dimensions, testing gaps and unresolved deviations.
  4. Obtain written project approval and confirm marking, packing, loading and replacement strategy.
