Read Article 3.2.2.81 below and answer question:

 

Do I need to provide a fire-resistance rating for a mezzanine under this Article?

3.2.2.81, Group F, Division 2, up to 2 Storeys, Sprinklered 

1) A building classified as Group F, Division 2 is permitted to conform to Sentence (2) provided

a) except as permitted by Sentences 3.2.2.7.(1) and 3.2.2.18.(2), the building is sprinklered throughout,

b) it is not more than 2 storeys in building height, and

c) it has a building area not more than

i) 4 500 m2 if 1 storey in building height, or

ii) 1 800 m2 if 2 storeys in building height.

2) The building referred to in Sentence (1) is permitted to be of combustible construction or noncombustible construction used singly or in combination, and

a) floor assemblies shall be fire separations and, if of combustible construction, shall have a fire-resistance rating not less than 45 min, and

b) loadbearing walls, columns and arches supporting an assembly required

to have a fire-resistance rating shall

i) have a fire-resistance rating not less than 45 min, or

ii) be of noncombustible construction.

🔥 The Most Expensive Code Mistake Is the One You Discover Too Late

 🔥 The Most Expensive Code Mistake Is the One You Discover Too Late

Part 2 of #PermitRisk Series

In the medical clinic project in Airdrie, AB, the classification issue wasn’t discovered at design stage. It was discovered when construction was approximately 90% complete. By that point, the conversation was no longer technical. It was financial.

What could have been:

* A conceptual correction during schematic design

Became:

* Demolition risk

* Alternative Solution development

* Over $100,000 in additional costs

* More than six months of occupancy delay

Here is the pattern I see repeatedly:

At Concept Stage → Corrections are analytical.

At Permit Stage → Corrections are coordinated.

At Construction Stage → Corrections are physical.

And physical corrections are always the most expensive.

Most permit problems are predictable.

They just aren’t reviewed early enough.

That’s why I advocate for a Pre-Submission Risk Review — not to replace design, but to stress-test assumptions before they become concrete.

If you’re working on a multi-storey project or tenant fit-up, and you want a second set of eyes before submission, feel free to reach out.

Have you ever experienced a “late discovery” that changed the entire project economics?
