About this level

Practical summary

Class 7110 sits in the PSIC 2019 hierarchy under M Professional, Scientific and Technical Activities > 71 Architectural and Engineering Activities; Technical Testing and Analysis > 711 Architectural and engineering activities and. This class usually fans out into more specific subclasses such as Environmental Engineering Activities, Architectural and other Engineering Activities, and Land Surveying Services. It is the level people use when they already know the activity family but still need the exact five-digit match.

Administrative context

Where this code is used

This class is used when a business can already narrow the activity family and only needs to compare the final subclasses such as Environmental Engineering Activities, Architectural and other Engineering Activities, and Land Surveying Services. It is the level most often checked before a five-digit decision is finalized.

Selection note

How to choose it

Use this class to choose between its final subclasses such as Environmental Engineering Activities, Architectural and other Engineering Activities, and Land Surveying Services. If two options look close, compare the exact activity, the outputs and the way the business actually earns revenue.

FAQ

What does PSIC Class 7110 cover?

PSIC Class 7110 is the four-digit layer that sits just above the final subclasses and usually defines the activity family for Architectural and engineering activities and related technical consultancy.

How do I compare Class 7110 with the sibling classes?

Read the neighboring classes and compare the exact wording of the child subclasses. Nearby options include nearby sibling codes.

Why does Class 7110 matter for a filing decision?

It is usually the last broad checkpoint before the five-digit subclass choice, so it is the right place to catch near-miss classifications.
