How reviews work

What a review reads

A review runs on the project as it stands when you start it:

• Every drawing page in the project, except pages you've skipped.
• Design standards: your workspace's and the project's, as text and as files.
• Reference files you've added to the project or the workspace, such as specifications and cut sheets.

It keeps a copy of what it ran with, so later uploads or page changes don't rewrite a past review.

Finding the diagrams

Each page arrives with a best guess at what it is, from its title block or, on untitled sheets, from the words on it. The reviewer treats those guesses as hints: it looks at each page and settles what it is before relying on it. A type you set yourself is an instruction it follows.

• One-line and riser diagrams are reviewed: every component on them is inventoried, traced and checked.
• Legends, notes and panel schedules are read for context: symbols, abbreviations, line types, general notes, and ratings the diagram leaves out. If a schedule and a diagram disagree about the same equipment, that's a finding.
• Everything else (floor plans, details, other disciplines) isn't used.

After a review, what it found about each page becomes the new best guess for the next one.

What gets checked

The reviewer applies your design standards to every component they cover, and checks the rest against the NEC and sound engineering practice, including:

• Bus and equipment ratings against the protective device; main breaker or main lugs stated; standard ratings.
• Conductor ampacity against the protective device, parallel sets, neutral size, and equipment grounding conductors (including upsizing when phase conductors are upsized).
• Transformer primary and secondary protection, secondary conductors, grounding and bonding, and voltages on each side.
• Ground-fault protection where required, fuse sizes, and interrupting ratings where the available fault current is given.
• Consistency between source, feeder and load: voltage, phase, wire count, poles, tags and callouts.
• Missing information needed to build or check the design.

It doesn't invent data. If a check needs a value the drawing doesn't give, such as a feeder length for voltage drop, the finding says what's missing.

Findings

Each finding is one distinct problem, even when it involves several components or repeats across several panels.

Credits

• One credit per drawing page a review runs on, each time it runs.
• Standards and reference files are free, and skipped pages aren't charged.
• A review can cover up to 150 drawing pages.
• Failed and canceled reviews are refunded automatically.

Credits belong to the workspace, so everyone in it draws on the same balance.
