Fire Damage Structural Assessment

After a fire, the first question is whether the building is safe, and the second is what can be saved. A licensed fire damage structural engineer answers both. Strut E&I evaluates fire-damaged homes and commercial buildings, documents what the fire did to the structure, and gives owners, adjusters, and attorneys an independent sealed report they can act on.

A fire scene gets crowded fast. The fire department, the insurance adjuster, a restoration contractor, sometimes a public adjuster, and the owner all need to make decisions. Most of those decisions rest on one structural judgment: which framing, beams, and walls are still doing their job, and which are not.

Soot and smoke make that hard to see. A joist can look badly burned and still carry its load, while a steel beam that barely changed color may have sagged out of level. Contractors and adjusters can estimate, but a licensed structural engineer is the person qualified to sign off on structural capacity. That signature matters when the scope of repair is in question, when a building official needs a reason to allow reoccupancy, or when a claim ends up in a dispute.

Our assessments fall under our broader forensic structural engineering practice. The method is the same one we use on any building failure: look at the evidence, measure it, and let the structure tell you what happened.

Before anyone starts tearing out drywall, the structure needs a first look. A post-fire safety evaluation checks for:

We tell you which areas are safe to work in, which need temporary shoring before anyone enters, and whether the building can be occupied at all.

Fire affects each building material differently. A useful assessment treats them separately.

Wood burns from the outside in. A charred layer forms on the surface and slows the burn of the wood beneath it. That is why heavy timbers often survive fires that destroy lighter framing. The structural question is how much sound wood remains. We probe and measure char depth on joists, rafters, studs, and beams, calculate the remaining cross-section, and check whether that reduced section still carries the required loads. Members next to the burn zone also get attention, because heat can weaken wood and connections that show little visible damage.

Steel does not burn, but it loses strength and stiffness as it heats, and it expands. Beams and columns can bow, twist, or sag, and connections can be overstressed as members expand and then cool. We check members for straightness and deflection, inspect bolted and welded connections, and look for signs that the steel reached temperatures high enough to change its properties. Steel that is still straight and within tolerance can often stay in place.

Concrete exposed to intense heat can spall, meaning chunks break off the surface, sometimes exposing reinforcing steel. Its color can change with temperature, which helps us estimate how hot it got. Masonry can crack, lose mortar strength, or shift. We document spalling depth and extent, check exposed reinforcement, and determine whether a slab, wall, or foundation element needs repair or replacement.

The water used to put out a fire can do its own structural damage. Thousands of gallons soak into subfloors, framing, and crawlspaces, and heavy wet debris adds load to floors that may already be weakened. We include water exposure in every assessment. For more on how water affects a structure over time, see our guide to water damage and structural integrity.

The most valuable part of the assessment is often the line between repair and replacement. Tearing out everything with soot on it is the most expensive path, and it is often unnecessary. Leaving damaged members in place is worse.

Every building is different, so the table describes common outcomes, not rules. The report spells out the decision for each damaged area.

Our report is written by a licensed structural engineer and sealed. It documents the damage with photographs and measurements, explains the structural condition of each affected area, and states what repair is required.

The report is independent. We work for whoever engages us, and our findings are the same no matter who reads them. Owners use it to understand their options. Adjusters and public adjusters use it to define structural scope. Restoration contractors use it to price and plan the work. Attorneys use it when the scope or cause of damage is disputed.

When a claim or construction dispute turns into litigation, our expert witness and litigation support team can provide testimony, rebuttal reports, and consultation. If you want to understand how forensic engineers work through a failure, read how forensic engineers investigate building failures.

An assessment tells you what is wrong. Repair design tells your contractor how to fix it. Strut E&I prepares sealed repair drawings for fire-damaged structures: replacement framing, sistering details, new beams and headers, connection repairs, and concrete or masonry repair details. These are the drawings building departments typically require before issuing a rebuild permit.

We do this for single-family homes, multifamily buildings, and commercial and industrial properties. Many fire repairs also involve broader changes to an existing building. Our structural rehabilitation services cover that work.

Some fire-damaged properties change hands before or after repair. If you are considering buying one, or you want a second opinion on a home that was repaired after a fire, a residential structural inspection will show whether the structural repairs were done right.

Strut Engineering & Investment, Inc. is a licensed structural engineering firm founded by Emad Badiee, who holds a BS and MS in Civil-Structural Engineering from UAB, has more than 16 years of experience, and is licensed in 28 states and the District of Columbia. Every project gets a dedicated licensed structural engineer.

Our Director of Construction, Ali Badiee, is a licensed General Contractor in Georgia, so our repair designs are written to be built. Clients rate us 5.0 stars on Google.

We assess fire-damaged buildings across Georgia, South Carolina, North Carolina, Florida, Tennessee, and New Jersey, as well as New York City, Washington, D.C., Pennsylvania, and Maryland. That includes Greater Atlanta and the surrounding metro.

If the fire reached the framing, roof, floors, or walls, yes. Smoke and soot hide structural damage, and only a licensed structural engineer can determine whether damaged members still carry their loads. Many building departments also require an engineer's evaluation or sealed repair drawings before a fire-damaged building can be repaired or reoccupied.

Often, yes. Many fires damage finishes, contents, and part of the framing while leaving most of the structure sound. The assessment identifies which members can stay, which can be reinforced, and which must be replaced. Sometimes the damage is extensive enough that rebuilding makes more sense, and the report will say so.

We remove the char layer and measure how much sound wood remains, then calculate whether that reduced section still carries the loads the member supports. We also check connections and members near the burn zone for heat damage. Appearance alone is not a reliable guide; a heavily blackened timber can be stronger than a lightly scorched small joist.

Our reports are independent, sealed by a licensed structural engineer, and based on documented measurements and photographs. Owners, adjusters, public adjusters, and attorneys all use them. We cannot speak for any insurer's decision, but a sealed engineering report gives everyone the same factual basis for the structural scope of the claim.

It can. Firefighting water saturates subfloors, framing, and crawlspaces and adds weight to floors through wet debris and collapsed ceilings. If framing is not dried and evaluated, it can decay later. We include water exposure in every fire damage assessment.

Yes. We assess fire damage in single-family homes, multifamily buildings, and commercial, industrial, and mixed-use properties, including wood, steel, concrete, and masonry structures. Commercial assessments often involve more parties and tighter schedules, and our reports are written to serve all of them.

The sooner the structure is evaluated, the sooner repairs, claims, and decisions can move forward. Strut E&I will tell you what is safe, what can be saved, and what the repair requires, in a sealed report you can rely on.
