What is a Structural Assessment Report?
A structural assessment report provides building owners and property managers with a clear understanding of how a building’s structural systems are performing. Think of it as a comprehensive physical exam or diagnostic snapshot of a building’s primary support system, like the skeletal system of a human body. Prepared by a licensed professional engineer after a site evaluation, the report documents observed conditions, evaluates the foundation and structural framing, identifies deterioration or performance deficiencies, and outlines recommended repairs, additional investigation, or preventive maintenance.
What the Report Should Tell You
A proper structural assessment report does more than list isolated conditions. It explains how the building is performing, identifies deficiencies that may affect the service or durability, and establishes a practical path forward. For property managers, the report should answer four fundamental questions: Is the structure performing as intended? What is causing the observed distress? Which conditions should be addressed first? What repair, monitoring, or maintenance measures are appropriate?
Overall Stability
The assessment should evaluate the building’s primary load-resisting systems, including foundations, load-bearing walls, floor and roof framing, beams, columns, and structural connections. Observations such as
- differential foundation settlement,
- excessive member deflection,
- corrosion-related section loss,
- connection deterioration, or
- displacement between structural components
should be documented and placed in context. The report should then explain whether these conditions affect structural integrity and/or warrant monitoring, analysis, stabilization, or repair.
Root Causes
Effective repair begins with identifying the mechanism behind the observed condition affecting structural integrity. For instance, when water penetrates unsealed concrete, chemicals in the water (typically chloride ions) reach the embedded steel bars, causing the steel to corrode, expand, and crack the surrounding concrete from the inside out (spalling). Other common examples of root causes affecting structural integrity include differential foundation settlement, excessive loading/impact, and water intrusion through the building envelope, which can come from
- design or construction deficiencies in framing systems and the building envelope,
- deterioration of the building envelope (roof and façade) waterproofing system,
- expansive or compressible soils and other subsurface distress,
- inadequate management of water (deficiency in drainage systems),
- vehicle impact,
- and hurricane-related loading.
Regarding the integrity of the building’s structural framing, including the foundation system, key indicators include binding doors, out-of-plane wall displacement, widening joints, or separation between building components.
Urgency Levels
Not every deficiency requires the same response. The report should classify each condition by its effect on building performance and the recommended repair time frame. Conditions such as foundation settlement, corrosion-related section loss, or deterioration of a load-bearing element may benefit from temporary support followed immediately by scheduled repair. Other conditions may be addressed through planned maintenance, longer-term repair scheduling, or periodic monitoring for changing conditions.
Actionable Steps
Recommendations in the report should address both the observed deficiency and its underlying cause. The report should define the repair method, priority, sequencing, and any need for temporary shoring, specialty design, testing, or construction-phase observation. Depending on the condition, corrective work may include
- foundation underpinning,
- structural framing repair/replacement,
- strengthening existing structural elements,
- structural repair of cracks via epoxy injection,
- removal and replacement of unsound concrete and repair of steel reinforcement,
- joint sealant replacement,
- restoration/replacement of waterproofing systems,
- or improvements to drainage systems.
Clear repair recommendations help owners develop a coordinated scope rather than relying on isolated maintenance measures.

What to Ask if Your Report is Missing Information
A report should provide enough technical context to support maintenance, budgeting, and repair planning. If the report does not clearly explain a material condition, probable root cause, or recommendation, then you should request clarification from the engineer or firm that prepared it. The following questions can help property managers determine whether the findings are sufficiently defined for informed decision-making.
What Caused the Damage?
The appropriate repair depends on the cause of the problem. The report should distinguish the visible symptom from the underlying cause and explain how that cause affects repair extent, sequencing, and anticipated cost. Conditions involving foundations and/or primary structural framing members must be evaluated by a structural engineer.
What is the Repair Scope?
A well-defined scope establishes the limits, objectives, and performance requirements of the work. It should identify
- affected structural or building-envelope components,
- anticipated repair quantities,
- access constraints,
- temporary stabilization requirements,
- compatible materials,
- and any testing or construction observation.
This information helps the owner develop repair documents, phase the work, obtain comparable contractor proposals, and prepare a realistic capital budget.
Do I Need a Specialist?
Some routine maintenance can be completed by a qualified general contractor. Work involving
- structural analysis,
- modification of load-bearing elements,
- foundation stabilization,
- diagnostic water-infiltration testing,
- or engineered repair details
may require a licensed professional engineer or a specialty contractor with relevant experience. The report should help you understand whether repair drawings, material testing, or construction-phase engineering services will be required for implementation of the recommendations in said report.
Choosing the Right Professional
Select a licensed engineer with experience evaluating the building’s structural system, construction materials, exposure conditions, and occupancy. Depending on the property, relevant experience may include
- concrete restoration,
- façade and parking-structure assessments,
- foundation evaluation,
- roofing and waterproofing systems,
- fenestration,
- repair design.
