How to inspect cold-formed metal framing

Step by step

1. 1

   Verify member size, gauge, and layout

   Confirm stud and track depth, flange, and gauge match the structural drawings for each wall type, and that spacing and layout are correct. Light-gauge and heavy-gauge studs look alike on the rack — the wrong gauge in a load-bearing or high wall is a structural defect.

2. 2

   Check tracks, anchorage, and base connections

   Verify top and bottom tracks are the right gauge, anchored to the structure at the specified type and spacing, and that the base connection matches the detail. Under-anchored track is the connection that lets a wall move or fail at its base.

3. 3

   Inspect stud-to-track and member connections

   Confirm connections are made per the drawings — screw type, size, and count, or welds of the right size by qualified welders where welding is specified — and that screws are fully driven, not stripped or standing proud. Count the screws at critical connections; under-fastened connections are the most common CFMF defect.

4. 4

   Verify bridging, bracing, and blocking

   Check that bridging or bracing is installed at the specified spacing and connected, and that blocking and backing for finishes, fixtures, casework, and handrails is in place. Bridging keeps the studs from rotating and buckling under load — missing rows are a hidden weakness.

5. 5

   Confirm deflection track and movement joints

   Verify the deflection or slip track at the top of non-load-bearing walls provides the specified movement and that fasteners don't pin the studs against deflection. A stud screwed tight through a slotted deflection track defeats the joint and cracks the finish above.

6. 6

   Check openings, headers, jambs, and knee walls

   At every opening confirm the header, jamb studs, and any built-up or boxed members match the drawings, and that the opening dimensions and reinforcement are right. Confirm parapet and knee-wall framing and its bracing at the roof.

7. 7

   Verify plumb, alignment, and coordination with MEP

   Check walls for plumb and alignment within tolerance, and confirm MEP crews cut and reinforce web penetrations per the details rather than randomly notching structural members. Oversized or unreinforced holes in a bearing stud reduce its capacity.

8. 8

   Document and release for cover

   Photograph connections, bridging, deflection track, and blocking against the checklist before sheathing or drywall, log any wrong gauge, under-fastened connection, or missing bridging as a nonconformance, and don't release the wall until it's cleared.

Questions people ask

How is cold-formed metal framing different from wood framing to inspect?

The logic is the same — verify members and connections before cover — but the details differ: gauge instead of grade, screws and welds instead of nails, bridging instead of blocking for lateral support, and deflection track for movement. Inspect against the structural drawings, since CFMF sizing is engineered.

Does cold-formed framing need special inspection?

Where it's load-bearing or engineered, welding and sometimes screw connections fall under special inspection per the statement of special inspections. Confirm the special inspector's coverage against the plan and record your own pre-cover walk regardless — both belong in the file.
