Property owners, real estate agents, and insurance adjusters frequently request structural engineering reports, but many are uncertain about what the document should actually contain. A structural engineering report is a professional technical document prepared by a licensed engineer that describes the condition of a building's structural system, identifies deficiencies or damage, and provides conclusions about safety, serviceability, and necessary repairs. In Nebraska, these reports serve as the basis for repair decisions, insurance claims, real estate transactions, and building code compliance.
Purpose and Scope of the Report
Every structural engineering report begins with a clearly defined scope. The scope establishes what the engineer was asked to evaluate and, equally important, what was not included. A report commissioned to evaluate a foundation crack will have a different scope than one assessing an entire building after storm damage. Property owners should understand that the report addresses only the conditions within its defined scope and should not be relied upon for conditions outside that scope.
The scope section typically identifies the property address and building description, the date of the site visit, who requested the report and why, the specific structural elements or concerns evaluated, and any limitations on the inspection, such as areas that were inaccessible or concealed.
Site Observations
The core of any structural engineering report is the documentation of site observations. This section records what the engineer found during the physical inspection of the property. It is factual and descriptive, presenting observations without immediately jumping to conclusions.
For a foundation assessment, observations might include the type and dimensions of the foundation system, the location, orientation, and dimensions of cracks, floor level measurements taken across the building, wall plumbness measurements, the condition of visible foundation elements, and the condition of the surrounding grade and drainage.

Photographic documentation accompanies the written observations. A well-prepared report includes photographs of every significant condition discussed in the text, with descriptions and reference markers that tie the photos to the written narrative. Photographs serve as a permanent record of conditions at the time of inspection and are particularly valuable when the report supports an insurance claim or legal matter.
Measurements and Testing
Depending on the scope, the report may include quantitative measurements beyond simple visual observation. Floor level surveys using a digital level or laser, crack width measurements using a crack comparator, plumbness checks with a digital inclinometer, and material testing such as concrete core sampling or wood moisture readings all provide objective data that strengthen the engineer's analysis.
Analysis and Discussion
Following the observations, the report presents the engineer's professional analysis of what the observed conditions mean. This section connects the factual observations to engineering principles and, where applicable, to building code requirements.
In Nebraska, the applicable building code for most jurisdictions is the International Building Code as adopted by the state or local authority having jurisdiction. The engineer's analysis may reference specific code sections, American Concrete Institute standards, American Institute of Steel Construction specifications, or other applicable engineering standards to support the technical conclusions.
The analysis section distinguishes between conditions that are cosmetic versus structural, active (ongoing) versus stable, and minor versus significant in terms of structural safety or serviceability. This distinction matters enormously to property owners and insurers, as the appropriate response differs dramatically between a stable cosmetic crack and an actively worsening structural deficiency.
Conclusions and Recommendations
The conclusions section distills the observations and analysis into clear statements about the building's structural condition. This is the section most readers turn to first, and it should be written in language that is technically precise but accessible to a non-engineer audience.
A thorough conclusions section addresses whether the observed conditions represent a safety concern, whether the building is suitable for its current or intended use, what repairs are recommended, the urgency of those repairs, and whether further investigation is warranted for conditions that could not be fully evaluated during the initial inspection.
Repair recommendations, when included, describe the engineering intent of the repair without necessarily providing complete construction-level details. A report might recommend that a cracked foundation wall be reinforced with carbon fiber straps or that a deteriorated beam be replaced with a steel member of specified minimum capacity. Detailed repair designs, including drawings and specifications suitable for construction, are typically provided as a separate engineering deliverable if the property owner decides to proceed with repairs.
The Engineer's Seal and Signature
In Nebraska, a structural engineering report must bear the seal and signature of the licensed professional engineer who prepared or supervised its preparation, in accordance with Nebraska Revised Statutes and the regulations of the Nebraska Board of Engineers and Architects. The engineer's seal represents professional accountability for the report's contents and conclusions. Reports without a proper seal and signature should not be accepted as authoritative engineering documents by building departments, insurers, or courts.
A well-prepared structural engineering report provides clarity where uncertainty existed. It gives property owners, buyers, insurers, and building officials an objective technical basis for making informed decisions about a building's structural condition and the steps needed to address any deficiencies.
