Engineering and design for custom metal buildings, steel structures, carports and related building projects.
Project-specific engineering plans, calculations and design coordination.

Gunderson Engineering supports commercial, industrial, agricultural and residential metal building projects. Share the proposed use, layout and project location so our engineers can review the design requirements and prepare a project-specific scope.
Engineering for the building’s dimensions, intended use and structural configuration, coordinated with the project drawings and available material information.
Structural engineering for storage, workshop, manufacturing and distribution uses. Provide the layout and operational requirements that affect the structure.
Engineering for metal homes, barndominiums, garages and other residential metal building applications.
Include the full property address and describe the work you are planning. Share the available records together, and identify anything still being prepared by another project team member.
Barnwell County government contact
Use the property address to ask which office handles the proposed work. The government contact identifies the jurisdiction; it does not establish a project-specific application requirement.
South Carolina’s Building Codes Council directs project-specific code questions to the building official for the property’s jurisdiction. Its FAQ distinguishes the Council’s role from local interpretation and administration.
Identify the city or county handling the application, then send its written request with the drawings that need engineering. Our engineering scope is confirmed separately from permitting and construction.
Keep the manufacturer’s building package, foundation request and property information together. A supplier’s standard package does not establish the site’s permitting jurisdiction or replace the agreed project engineering.
The proposed building use and layout guide the engineering scope. Include available building-system information, intended openings and known site requirements when you contact the team.
Our work provides engineering information for your design team and contractor. The proposal identifies the drawings and calculations to be delivered, and the reviewing authority determines the permitting requirements.
Use the available plans and actual agency comments to define the work.
Projects include commercial warehouses, industrial buildings, agricultural structures, barndominiums, garages, carports and other custom metal structures.
We provide engineering drawings and supporting documentation within the agreed scope. Permitting requirements and approval decisions remain with the reviewing jurisdiction.
No. We provide engineering and design services. Fabrication, construction and installation are performed by your selected contractors.
Together, Florida Engineering, Lightning Engineering and Gunderson Engineering provide professional engineering across 23 licensed states. Choose your project state to reach the responsible company.
