Inputs and assumptions
Trace loads, dimensions, material properties and performance criteria to the project documents. Check units and whether the assumptions match the proposed work.
Part of submittal review
Check the calculations behind your submittal
We check engineering calculations against project requirements, governing equations and drawings, so your team can resolve errors and missing information before fabrication or installation.
One submittal package
From submitted calculations to review comments
Upload the package
Include the calculations, shop drawings, product data, contract drawings, specifications and prior comments.
Trace and recompute
We trace inputs to the project requirements, check formulas and arithmetic, and compare the results with the submitted drawings.
Resolve with the sources
Review findings with references to the calculation page, design requirement and governing section or equation.
Across your submitted calculations
What we check
From steel connections and cold-formed framing to other submitted systems, we review the calculations together with the design they need to match.
Equations and arithmetic
Check the governing standard and edition, formulas, factors, unit conversions and arithmetic. Recompute the checks behind a finding.
Calculations vs. drawings
Compare calculated sizes, materials, capacities and geometry with the shop drawings, schedules and product data.
Missing checks
Look for required checks, design conditions or supporting calculations omitted from the submission.
Coverage and locations
Map each calculation to the items and locations it covers. Check that typical calculations apply to the sizes, conditions and demands where they are used.
Revisions and prior comments
Check the submission’s revision and reconcile earlier calculation comments with what was supplied.
Findings you can act on
See what needs to change, and why
Findings distinguish an incorrect input, a calculation error, a drawing mismatch and a missing check. Each comment identifies the affected calculations and locations, with the evidence behind it.
For example, in a steel connection review we check whether the calculation includes the forces shown on the structural drawings and whether the calculated bolts, welds and plates match the shop detail.
Questions, answered
FAQs
Is calculation review part of submittal review?
Yes. Upload the submitted calculations with the shop drawings, contract drawings and specifications they need to match. We review them as one package.
What calculations does this page cover?
Engineering calculations submitted with your shop drawings and submittals, including steel connections, cold-formed framing and other submitted systems. The review follows the requirements and calculations in your package.
Which code edition is used?
The edition required by the project documents and adopted building code, with the stated design method. Findings cite the relevant specification section or equation.
What if a load or calculation is missing?
We identify the missing information and affected items. Missing design criteria go back to the responsible designer for clarification.
Does this approve the design?
The review provides findings for the responsible engineer to verify and resolve. Final design decisions and submittal disposition remain with the project’s authorized professionals.
