Stamped Structural Calculations — frequently asked
How do calculations differ from a letter?
A letter explains the evaluation and findings in narrative form. Calculations show the engineering analysis supporting the conclusions. Some projects require both.
How do calculations differ from construction drawings?
Calculations demonstrate the structural analysis; drawings show how the work is built. Some projects require calculations plus drawings to fully document the scope.
Why might I need a combination?
The permitting authority may require a letter, calculations, and drawings together depending on the project. The appropriate combination depends on your project and jurisdiction.
