What happens during structural wall removal

Taking out a load-bearing wall is routine when it is planned properly. Here is what that plan looks like.

First, find out what the wall is holding up

Before any wall comes out, an engineer traces the loads above it: floors, roof, and sometimes a point load from a post you cannot see from the room.

‍

Many older Calgary bungalows have walls that look like partitions but carry the roof. Guessing is how ceilings start to sag.

‍

A beam and posts take over the load

The engineer sizes a beam to carry what the wall carried, and posts to bring that load down to a footing that can handle it.

‍

What the engineer checks
  • Loads from floors and roof
  • Point loads from above
  • The footing under each post
  • Beam depth and headroom
  • Temporary shoring plan

Temporary walls come first

Before the old wall is touched, temporary shoring walls go up on both sides to hold everything while the new beam goes in.

‍

A permit is required

Removing a load-bearing wall in Calgary needs a building permit and stamped drawings. The inspector checks the beam before it gets covered up.

‍

Typical order of work
  • Engineer site visit
  • Permit issued
  • Shoring installed
  • Wall removed, beam set
  • Inspection, then finishing

‍

Usually done in a week or two

Once the permit is in hand, most wall removals take one to two weeks, including drywall and paint.
