Structural Condition Assessment

Something in an existing building looks wrong, or somebody has told you it is wrong, and you need a licensed engineer to look at it and put an opinion in writing. That is a condition assessment.

I visit the structure, document what is actually there, determine whether what you are seeing is a structural problem, and write up what I found and what I recommend. Turnaround on the written report is typically 2 to 5 business days after the site visit, depending on the complexity.

Common Reasons People Call

Visible distress. Cracks in foundation walls or slabs, sagging floors, bouncing floors, doors that no longer close, separation at wall and ceiling joints, or a roof line that is no longer straight.

Water and rot. Crawlspace framing with moisture damage, sill plates and rim joists showing decay, or columns bearing on deteriorated material. This is a frequent one, and the extent is usually different from what is visible at first.

A change of use or a new load. Converting an attic to living space, putting equipment on a roof, adding storage to a floor designed for something lighter, or removing a wall. The question is whether the existing framing can take it.

A real estate transaction. A home inspector flagged something and wrote "recommend evaluation by a structural engineer." That sentence is what brings a lot of people here, and quite often the answer is that the condition is not structural.

Prior repairs of unknown quality. Work done by a previous owner with no drawings and no permit, and nobody knows whether it was adequate.

An insurance or dispute question. An independent written opinion on the cause and extent of damage.

What the Site Visit Covers

The visit is where the assessment either succeeds or fails, because everything afterward depends on characterizing the structure correctly.

I measure and record the framing that is accessible: member sizes, spans, spacing, species or grade where it can be determined, connection types, and the bearing conditions at each end. I trace the load path from the area of concern down to the foundation, because the problem is often not where the symptom appears.

I document conditions photographically, measure the distress itself where it can be measured, such as crack widths, floor slope, and out of plumb, and note whether the evidence suggests movement that is ongoing or movement that stopped years ago. Those two lead to very different recommendations.

I also record what I could not see. Framing behind finishes, below grade, or inside a wall cavity is not observable without opening it up, and a report that quietly omits that limitation is not worth much.

Determining Whether It Is Actually a Problem

Distress and damage are different things. A great deal of what worries people is cosmetic, or is the result of movement that completed long ago and is stable. Some of it is a structure operating with less capacity than it needs.

Telling them apart means analyzing what is there against what the code requires for the loading the structure actually carries, using the member sizes and spans I measured rather than the ones the original drawings may have shown. Where the original design basis can be inferred, I note it, since a structure built to a 1974 code is not required to satisfy a 2026 one unless the use is changing.

If a repair is needed, I say what it needs to accomplish structurally. Depending on the scope you want, that is either a recommendation your contractor works from or a designed and stamped repair detail.

What the Report Contains

A description of the structure as I found it, with the measurements and photographs supporting it. A statement of what was observed and what could not be observed. My engineering opinion on whether the condition is structural, what is causing it, and whether it is stable or progressing. Recommendations, in order of urgency. And the limitations of the assessment, written out plainly.

The report is stamped, within my licensed disciplines in Ohio, Kentucky, California, Texas, Florida, and Louisiana. It is written so that a contractor, an insurer, a buyer, or a building official can follow the reasoning rather than having to take the conclusion on faith.

What a Visual Assessment Cannot Tell You

A visual condition assessment is not a code compliance review of the whole building, and it is not a home inspection. It addresses the structural question you asked about.

Concealed framing cannot be evaluated without removing finishes. Foundation conditions below grade cannot be evaluated without excavation. Soil behavior underneath the foundation cannot be determined by looking at the building, and where settlement is the suspected cause, a geotechnical investigation may be the next step. Material strengths can be assumed conservatively from what is visible, or established by testing if the question warrants it.

Where one of these limits the conclusion I can reach, I tell you before the visit if I can foresee it, and in the report if it emerges during the work.

What to Send Me

Enough for me to tell you whether you need an engineer at all, which is sometimes the answer:

• Photographs of the condition that concerns you, including a wide shot showing where it sits in the building
• The address, and roughly when the structure was built
• What changed, and when you first noticed it
• Any inspection report, if an inspector raised it
• Any drawings of the building, if any exist
• Whether you need a stamped report, and for whom

I am in Dayton, Ohio and travel for site visits in the region. For work outside driving distance, some assessments can be done from good documentation and photographs, and I will tell you honestly when they cannot. Contact me with what you have. The initial consultation is free.
