What a structural project file can look like.

A fictional demonstration: an opening between a living room and kitchen. Explore the related questions and documents.

Demonstration — not for construction
This fictional project contains no usable section sizes, load values or construction details. The drawings show how information is organised. They are not calculations for an existing home.
Load-bearing wall — Existing situation

01. Existing situation

The starting point and the existing load-bearing structure.

Load-bearing wall — Proposed situation

02. Proposed situation

Your desired layout, before the technical assessment.

Load-bearing wall — Structural concept

03. Structural concept

A possible load path. Detailed design is project-specific.

Demonstrations • concept details, not suitable for construction. No usable beam sizes or design load values are provided.

1. Existing and proposed situations

The fictional client wants to connect the living room and kitchen. The existing load path needs investigation before selecting a replacement concept. A real project file includes relevant storey plans, sections and available foundation documents.

2. Design basis and loads

The structural engineer determines which floors, walls and other elements transfer loads to the wall being altered. Self-weight, use and other relevant loads are established for the project. Numerical values are deliberately omitted from this demonstration.

3. Beam, bearings and load path

One possible solution uses a beam with suitable supports. This is only one concept. The structure beneath the bearings and the building's stability help determine suitability. Real calculations check these relationships within the agreed brief.
