Homeowner questions

Structural Drawings: questions for Welland homeowners

What projects can structural drawings cover?

We prepare structural drawings for renovations, additions, repairs and new residential construction. New homes, garages and additions may require coordinated plans showing foundations, framing and the connections between those parts.

What is shown in the drawing package?

It shows the designed members, supports, reinforcement and connections needed for the structural work. Beam and post details need coordination with the foundation beneath them, rather than a member size without an explanation of bearing.

Do structural drawings replace architectural plans?

No. Structural drawings explain support, while architectural plans address other aspects of the building design. Structural details alone should not be treated as a complete permit package for every part of the renovation or new home.

Can drawings be prepared without original house plans?

Yes, but the design needs reliable information about the existing construction it depends on. Photographs can explain some hidden work, although they may not show enough detail to establish member sizes and bearings.

Do the drawings include calculations?

Calculations support the structural design, with the information provided matched to the project’s requirements. Where an existing support is retained, calculations need a reliable basis for its material, size, condition and loading.

Can the drawings be used for a permit submission?

Structural drawings can form part of a permit submission where engineering documentation is required. Comments on the structural information can require clarification, calculations or revised details after the initial package has been reviewed.

Can the contractor suggest different members or details?

Yes. A defined alternative can be reviewed for its structural effects before it replaces the design. The engineer needs enough information about the proposed substitution to assess it against the actual conditions of the project.

Do permanent drawings include temporary support?

Temporary support during construction may require separate engineering from the finished structural design. The contractor’s planned sequence can influence temporary requirements and needs coordination where the structure is altered in stages.
