Which type of inspection is typically the first step in assessing concrete decks?

The first step in assessing concrete decks is typically a visual inspection. This type of inspection involves a thorough examination of the bridge's surface to identify any visible signs of distress or deterioration, such as cracks, spalling, or surface discoloration. The visual inspection allows the inspector to gather important preliminary information about the condition of the concrete deck without the need for specialized equipment or intrusive methods.

By identifying any obvious issues during this initial phase, the inspector can prioritize areas that may require further investigation and determine whether a more detailed assessment—such as physical, structural, or advanced inspections—is necessary. This foundational step is crucial, as it lays the groundwork for understanding the overall health of the bridge and ensures that any underlying problems can be addressed in subsequent evaluations.
