Planning a Wall Opening: Information Your Engineer Needs

A proposed wall opening can affect more than the wall visible in the room. An engineering scope needs to consider the actual framing arrangement, the proposed change and how loads are supported through the building.

Show the existing and proposed layout

Provide an existing floor plan and a marked-up proposed layout, if available. Identify the wall or portion of wall involved, the desired opening, adjacent rooms and any planned work above or below. Label approximate dimensions clearly as preliminary until verified in the field. Include the project address and the owner’s intended use of the space.

Document accessible existing conditions

  • Overall photographs of both sides of the wall and the adjacent spaces.
  • Available floor, roof, foundation or previous remodel drawings.
  • Photographs of accessible framing above or below the area, where safe.
  • Known beams, posts, masonry, mechanical equipment or other features close to the work.
  • Details of earlier alterations and any relevant permit or inspection comments.

Do not infer that a wall is non-load-bearing from its direction, appearance or a single photograph. The engineer determines the investigation and design inputs needed for the actual structure.

Agree what will be evaluated

The project review establishes whether the engagement calls for an existing-condition assessment, design calculations, structural drawings or a combination. Where structural design is included, the scope addresses the affected load path and the information needed about supports and connections. A contractor’s intended construction sequence and temporary support arrangements also need appropriate professional consideration; the intake checklist is not a construction or shoring design.

Coordinate the submittal and field visit

Share the architect’s plans, the permitting jurisdiction and any written building-department requirements. The responsible professional confirms which documents are needed and whether additional investigation is required. Keep the proposed work on hold until the required design, approvals and construction arrangements are in place.

Request a project-specific scope

See load-bearing wall evaluations, beam sizing and residential permit drawings. Grand Street confirms the scope, engineering deliverables, fee and schedule before work begins. A particular permit outcome or design solution is not established by an intake photograph.
