Question 1

Are your inspectors licensed Professional Engineers?

Accepted Answer

Yes. Every inspection is performed by a licensed North Carolina Professional Engineer (PE) - never an intern, technician, or engineer-in-training. The same PE who walks your property writes and stamps your report. Triangle Structural Engineering is a licensed NC engineering firm (License #P-3406).

Question 2

How much does structural design for a renovation cost?

Accepted Answer

PE-stamped structural design for residential renovations in the Triangle typically ranges from $750 to $2,500 depending on project scope (single beam vs. full addition), complexity, and whether existing architectural plans are provided.

Question 3

Do I need a structural engineer for my renovation?

Accepted Answer

If your renovation involves removing walls, adding floors, changing roof lines, building an addition, or modifying load paths, a licensed PE is typically required by North Carolina building code and your local permit office.

Question 4

How long does it take to get permit-ready structural plans?

Accepted Answer

Most renovation structural designs are delivered in 3-7 business days from the on-site visit, depending on project complexity. Simple beam designs can be turned around in 1-2 business days.

Question 5

Can you work with my architect or contractor?

Accepted Answer

Absolutely. We regularly collaborate with architects, designers, and general contractors throughout Raleigh, Durham, Cary, Apex, and the wider Triangle to deliver coordinated, permit-ready documents.

Question 6

What do I need to provide to start the design?

Accepted Answer

Architectural plans, sketches, photos, or even a clear description of what you want to accomplish. We will guide you through what additional information is needed and handle the engineering from there.
