Section 10: Special Inspections
Overview
Special Inspections are typically performed to monitor a known or suspected deficiency at a specific location
or to document repairs performed
. These inspections can be recurring or performed on an as-needed basis. The level of inspection will vary based on the type of deficiency but shall be sufficient in scope and detail to collect all necessary information such
that an engineering evaluation can be made. These inspections are limited in nature and do not satisfy the NBIS requirements of routine, underwater, nor NSTM inspections. Generally, a Special Inspection is to be performed by a qualified team lead. A special inspection must be performed by a qualified team lead when the purpose of the inspection is to re-evaluate a condition rating. In cases where a qualified team lead is unnecessary (e.g. monitoring settlement), individuals must be approved by the Bridge Inspection Program Manager based on the scope of the Special Inspection.
Example of Special Inspections are:
- Monitoring the settlement of a specific bent every 6 months
- Monitoring the condition of a specific pin and hanger assembly every 3 months until the bridge is replaced
- Performing a one-time up-close inspection of a bridge deck soffit on a flyover using an under-bridge inspection unit due to conditions discovered in a recent routine inspection
Include all documentation and inspection procedures from Special Inspections in the permanent bridge inspection file in AssetWise, TxDOT’s Bridge Inspection Management System.
A Special Inspection may be used to monitor localized deficiencies in lieu of a reduced interval Routine Inspection when the reason the bridge needs a reduced Routine Inspection is due to localized deficiencies.
A Special Inspection can be used to monitor localized underwater deficiencies of the bridge in lieu of a complete underwater inspection
