ENGINEERING DESIGN SUBSTANTIATION
When a building department requests engineering calculations, the key is to document the structural design assumptions and checks that apply to your specific project.
What Is This Service?
Structural calculations are engineering analyses used to evaluate loading, member capacity, stability, deflection, anchorage and other relevant structural conditions. Calculations may support structural drawings and must be prepared or accepted by an appropriately qualified professional where required.
Who Is This Service For?
Common Project Challenges
The city requests verification of a proposed beam or header.
Wind uplift or footing adequacy is questioned.
Structural details reference sizes with no supporting engineering basis.
Included Scope
The exact scope is tailored to your project and confirmed in your written quotation. Depending on the requirements, the work may include:
Permit Review Context
Structural calculations support the design shown on structural drawings. Reviewers may request calculations for beams, foundations, lateral systems, retaining walls or other engineered elements depending on project complexity and jurisdiction requirements.
We use these topics to frame the drawing scope, but the final submittal requirements are set by the city, county or other reviewing authority for the project address.
From Intake to Deliverables
Send the address, proposed scope, available files and reviewer comments.
We identify missing information and agree on the proposed scope, deliverables and quotation.
The contracted documentation is prepared using the inputs and relevant project requirements.
You check the drawings; agreed corrections and final deliverables follow the written scope.

Frequently Asked Questions
Photos alone are rarely enough. Accurate spans, loads, support conditions and material information are usually required.
They may be. The quote will explain whether the package includes calculation sheets, updated drawings or both.
When permitted by the jurisdiction and agreed to by the licensed professional, digital signing and sealing may be possible.
An existing structure may require field investigation and additional evidence; calculations alone do not establish actual construction condition.
Send the property address and a short description of the proposed work. We use the jurisdiction and project type to define the likely drawing scope before drafting begins. Final submittal requirements remain subject to the reviewing authority.
Yes. Existing surveys, recorded plats, sketches, photos, prior plans and correction comments can all help establish the drawing scope and reduce avoidable assumptions.
Yes. Make A Site Plan supports projects across the United States. Because permit procedures vary by city and county, we check the project location before finalizing the scope.
No. Approval is controlled by the reviewing jurisdiction. Our process is designed to make the drawings clear, coordinated and responsive to the known submittal requirements, and we support in-scope permit comments when they occur.
