A pre-blast survey is a professional inspection and documentation of the condition of a structure before nearby blasting, mining, or heavy construction activities begin. The survey records existing conditions using photographs, notes, measurements, and floor plan diagrams so any changes after blasting can be accurately evaluated.

Pre-blast surveys protect both property owners and project operators. By documenting existing conditions before vibration-producing work begins, these inspections help prevent disputes and reduce unnecessary damage claims by clearly establishing the condition of structures beforehand.

During a pre-blast inspection, a trained inspector documents the interior and exterior condition of a structure. This typically includes walls, ceilings, foundations, driveways, and other visible components, along with high-resolution photographs and written notes of any existing cracks or defects.

In most cases, pre-blast inspections are voluntary for property owners. However, allowing the inspection provides an accurate record of the property’s condition and can help resolve concerns more easily if a claim is filed later.

A post-blast inspection is conducted after blasting or vibration-producing operations occur. The inspection evaluates the current condition of a property and compares it to the documentation from the pre-blast survey to determine whether any new changes have occurred.

Professional investigators review inspection documentation, blasting logs, vibration monitoring records, and seismograph data. These records help determine whether the vibration levels were capable of causing the claimed damage or if the conditions likely resulted from other factors.

A blasting seismograph is an instrument used to measure ground vibrations and air pressure waves produced by blasting. The device records vibration levels and provides data used to confirm compliance with established safety standards and regulations.

When blasting operations follow industry regulations and vibration standards, they are designed to prevent damage to nearby structures. These standards are based on extensive research and are intended to protect even the most sensitive parts of a building such as drywall and plaster.

Most structural cracks found after blasting are often the result of normal building movement, temperature changes, or natural settlement. A professional inspection and review of vibration data are necessary to determine whether blasting could have contributed to the damage.

Claims investigations may involve blasting, pile driving, quarry operations, mining activities, heavy construction equipment, or other vibration-producing operations. Smith Adjusting evaluates these claims using inspection documentation and technical analysis.

Most inspections take between 30 minutes and two hours depending on the size of the property and the level of documentation required. Larger or more complex structures may require additional time.

Smith Adjusting provides inspections and claim investigations across Kentucky, West Virginia, Ohio, Virginia, Pennsylvania, Tennessee, Georgia and surrounding regions depending on project needs.
