How to read this page
Four kinds of pricing, clearly labeled
Every price on these pages falls into one of four categories, so you always know whether you’re looking at a floor, a range, an hourly service or a project that needs a custom proposal.
Starting At
The typical minimum fee for the simplest version of that service. Most projects land above the starting price.
Typical Range
Where most comparable projects fall. Larger, more complex or poorly documented projects can exceed the range.
Hourly Rate
Time-based billing at our published rates — used for consultation, undefined scope and additional services.
Custom Quote
Projects that require a scope conversation before pricing. We’ll review your information and propose a fee.
Pricing shown on these pages is intended as budgeting guidance. Final pricing depends on project size, complexity, existing documentation, site conditions, permitting requirements and the final engineering scope.
Engineering documents are signed and sealed only after the appropriate engineering evaluation, design and professional review have been completed. PEC does not sell an engineering stamp separately from professional engineering services.

FAQ
Engineering Pricing Questions, Answered
How much does a structural engineer cost in Louisiana?
For most residential and light-commercial work in Louisiana, stand-alone structural engineering services run from about $750 for a simple PE review or letter to $7,500+ for a complete new-residence structural package. Larger commercial and industrial structural packages typically range from $3,500 to $12,000+. The category pages above break the typical ranges down by service so you can budget realistically before requesting a quote.
How much does it cost to get engineering drawings stamped in Louisiana?
PEC does not sell a stamp, and no reputable Louisiana engineering firm does. Engineering documents are signed and sealed only after the required professional engineering work and review have been completed — the seal certifies that a licensed engineer has taken professional responsibility for the work. What you’re actually buying is the engineering: a review of plans prepared by others typically starts around $750–$1,500, and the fee grows with the amount of verification, redesign or supplemental engineering the documents need before they can responsibly be sealed.
What information should I submit to get an engineering quote?
The more you send, the tighter the quote. Helpful items include:
- Project address
- Building dimensions
- Intended use
- Existing drawings
- Architectural plans
- Metal-building drawings
- Manufacturer reactions
- Site photographs
- Survey
- Geotechnical information, if available
- Permit comments, if already issued
- Desired schedule
