Quick Answer
A wall that supports the weight of the building above it and cannot be removed without structural work.
Definition
Definition
A wall that carries vertical loads from the structure above and transfers them to the foundation. Bearing walls are structural elements and cannot be removed without providing an alternative load path. They differ from partition walls, which only divide space.
Context
Why It Matters in Bidding
Identifying bearing walls is critical on renovation and tenant-improvement bids because removing or altering one requires engineered shoring, a new beam or header, and an alternative load path, all of which carry cost and schedule that a partition-only assumption ignores. Misclassifying a load-bearing wall as a simple partition during takeoff is a classic source of major change orders once demolition exposes the real condition. Estimators who flag bearing walls early can price temporary support, structural framing, and the engineering required to maintain stability during the work.
Example
Example
Walking a retail buildout, the estimator spots that the wall the tenant wants opened up is load-bearing, so she carries a line item for temporary shoring, a new structural header, and the structural engineer's design rather than pricing it as a standard demo.

FAQ
Questions Contractors Ask
How do you tell a bearing wall from a partition during estimating?
Check the structural drawings for walls that carry framing above, run perpendicular to joists, or stack continuously across floors down to the foundation. When drawings are missing on a renovation, assume continuity and field-verify, since misjudging a bearing wall as a partition is a common and costly takeoff error.
What costs are involved in removing a bearing wall?
Removing a bearing wall requires structural engineering, temporary shoring while work proceeds, and a replacement load path such as a beam or header with adequate posts and footings. There may also be permit and inspection costs. Each of these should be a distinct line item, not absorbed into a general demolition allowance.
Why are bearing walls a frequent source of change orders?
On renovations, demolition often exposes load-bearing conditions that were not obvious from a walkthrough or were undocumented on old drawings. If the bid assumed a simple partition, the discovery forces added shoring, framing, and engineering. Flagging suspected bearing walls and clarifying assumptions in the proposal reduces this exposure.
