An assembly check before finishing catches problems while correction may still be simpler.

An assembly check before finishing catches problems while correction may still be simpler. Define the checks from the approved drawings, hardware requirements, and project standards. Avoid a generic pass that does not identify what was verified.

## Check readiness

- Confirm cabinet identity, dimensions, orientation, and current revision.
- Verify required components, exposed edges, and preparation work.
- Check fit and interfaces that the next operation depends on.
- Identify defects or incomplete work with a clear disposition.

## A useful checkpoint

A hypothetical cabinet is structurally assembled but missing a required machined opening. If the omission is discovered after finishing, recovery may involve additional handling and surface repair. The prefinish check should include requirements that are difficult to correct later.

## Learn from escapes

Review defects found downstream and update the checklist only when a repeated or consequential risk justifies it. Keep the checklist focused enough to be used consistently.

## How Millbase can help your shop

### Keep the shop’s operational picture connected

For a cabinet or millwork project, [Millbase project tracking](https://millbase.ca/#projects) connects the job, sub-projects, tags, recorded labour, and material costs. Pair that context with [inventory records](https://millbase.ca/#inventory) when reviewing the materials used and the work still being discussed. Keep the approved drawings and manufacturer requirements available through the shop’s established document process.

Ask the [Millbase AI agent](https://millbase.ca/#how-it-works) a question grounded in your workspace records. For example: *“Show the recorded labour and material costs for this cabinet project, and who has worked on it.”* You can select a project or worker, ask follow-up questions, and request [supported reports and CSV exports](https://millbase.ca/#insights).

Use the answer to prepare a focused review of the job. It does not establish hardware compatibility, approve a drawing revision, or replace a manufacturer’s instructions or the contract specification.

## Frequently asked questions

### Should every cabinet use the same checklist?

A common core can help, with job-specific checks for unusual designs or requirements. Do not let the standard list replace the drawing.

### Who owns an incomplete item?

Assign a named role and next action before the assembly leaves the checkpoint.
