In cases where there are no specific navy requirements, the work shall meet the minimum requirements of the nbis (reference b). The inspection type required for each structure is listed in the bridge schedule . The a-e shall inspect and determine the structural condition of all bridge components including fracture critical details when applicable. In addition, the a-e shall document any completed repairs and note any conditions that have changed since previous inspection reports. All components will require an arm s length visual inspection using simple tools, measuring devices, and recording methods. The a-e shall be responsible for providing all access equipment. During routine inspections, the inspection team must verify all data, correct inconsistencies, and/or update the data on the SI & a form. Underwater inspection: during the inspection of submerged bridge elements, the a & e shall check foundations for scour and undercut and use soundings, visual inspection, and probing to determine extent. Underwater inspections shall be accomplished in accordance with the requirements for level i, II, and III (if warranted) inspections described in reference (c). Findings shall be included with the topside inspection report. Diving operations shall be conducted in accordance with the EM-385-1-1, section 30, contract diving operations (reference d).

Scour assessment: during the inspection process, the a-e shall obtain all pertinent data required to determine if a full scour analyses is warranted. Soundings of the channel bottom shall be taken around each of the substructure units across the channel, along the upstream and downstream fascias of the structure at a minimum. If deemed necessary at the time of inspection, additional soundings should be taken along lines parallel to the upstream and downstream fascias. Seismic assessment: during the inspection process, the a-e shall obtain all pertinent data required to determine if a full seismic analyses is warranted based on current seismic requirements for the state or governing region. Bridge inspection report: bridge inspection reports will be created utilizing inspecttech software, the navy s bridge report generation utility. The a & e will populate all fields as applicable. Structural inventory and appraisal (SI & a) sheet: the SI & a sheet shall be created using the inspecttech software and shall contain all items required by fhwa in the latest edition of reference (c). The SI & a shall include all related measurements in units of meters. Item 16 (latitude) and ITEM17 (longitude) shall be in units of degrees, minutes, and seconds to the nearest hundredth of a second using GPS methods. Information on average daily traffic (ADT) must be provided. SI & a data shall be checked with the latest version of the fhwa edit/ update program and corrections to the data made before submittal.
