We provide fire protection engineering for facilities nationwide, including high-piled storage, hazardous materials, sprinklers, fire alarm, fire access, smoke control, inspections, permitting, and the plan review that goes with that work.
High-Piled Storage
- Commodity classification
- Storage arrangement analysis
- HPS permit support
- AHJ coordination
High-Piled Storage
We classify the commodities you store and look at how the arrangement affects the permit. We prepare the storage layout and written report reviewers usually expect, and we help you work through questions from the authority having jurisdiction. If the design needs a second look, we review the arrangement and the protection approach before you submit.
Hazardous Materials
- Hazard classification
- MAQ analysis
- Control-area evaluation
- HMIS / HMMP support
Hazardous Materials
We review the materials you keep, the quantities in each area, and how the building is divided. When a quantity is over the usual limit, we set out practical options and check the plans that go with the storage. We also look through the inventory for materials that are missing or misclassified.
Third-Party Plan Review
- Independent design review
- Fire sprinkler and fire alarm
- Alternative methods analysis
- AHJ approval support
Third-Party Plan Review
We review designs independently so code issues show up before you submit. That covers sprinkler and fire alarm work as well as other fire protection and alternative approaches, with comments aimed at a cleaner approval. We read the drawings the way a reviewer would and point out what to change before the package goes in.
Additional services
Beyond high-piled storage and hazardous materials, we review fire protection drawings, access, and smoke-control submittals; witness acceptance testing; support inspections and alternative-methods requests; and provide plan review and training for fire departments and project teams.
-
Independent review of sprinkler drawings and hydraulic calculations so issues show up before you submit. Contractors and design teams use this when they want an FPE to check the plans first.
-
Independent review of fire alarm drawings and device layouts before submittal. The aim is a cleaner package and fewer comments once the plans reach the reviewer.
-
Review of smoke control approaches and related submittals, including an existing analysis the design team already has, so the approach is clearer before AHJ scrutiny.
-
We witness fire alarm, sprinkler and smoke control acceptance tests and help you get ready for pre-acceptance inspections, so systems are ready for sign-off. We review and witness the testing; your contractors perform it.
-
Practical alternative materials and methods requests when a prescriptive layout will not work, written as an alternate means and methods path the authority having jurisdiction can consider.
-
Review of fire apparatus access for the site and building so access comments can be addressed in the site plan before they delay the project.
-
Outsourced fire plan review for fire departments that need additional review capacity, so plan packages can keep moving when in-house bandwidth is tight.
-
Fire protection and code training for facility teams, contractors, and fire department staff, scoped to the questions the team actually has to handle.
From scope to approval
Clear scope up front. Practical answers.
We start by learning how your facility operates and which fire protection and code questions you need answered. Before any work begins, you'll know the scope, deliverable, and timeline. From there, you get practical guidance that helps move your plans to approval without unnecessary complexity.

Practical Storage Limits
Height limits and commodity separation are common ways to reduce the scope of high-piled storage requirements while still using available storage height.
