Inspection - In-Depth

A hands-on, close-up inspection of one or more structure elements above or below the water level to identify any deficiencies not readily detectible using Routine Inspection procedures. An In-Depth Inspection is also used to identify developing problems that impact present service requirements or to obtain detailed information needed to facilitate the preparation of structure rehabilitation plans. This inspection may result in a full investigation including structural analysis to determine member capacity that will be used in a revised load rating. It may be performed independently from a Routine Inspection at intervals other than 24 months. It can be at a longer interval or one time only. Analogous to a Special Inspection for railroad bridges.
