Adhere to the step-by-step instructions for entering the data in the electronic Bridge Inspection Management System as presented in the Coding Guide and SNBI. Follow coding and documentation requirements outlined in this chapter regardless of whether inspections are carried out in-house or by consultants. This requirement ensures statewide consistency in documenting and reporting inspection findings. The Coding Guide also includes interpretations, examples, and other data input guidance and the SNBI has specification, commentary, and examples to assist with coding. The electronic Bridge Inspection Management System contains a record for each Bridge Class Structure on public roadways including private bridges that are connected to a public road on both ends of the bridge, temporary bridges, and bridges under construction with portions open to traffic in Texas. The definition of a Bridge Class Structure is described in Item 112 in the “Coding Guide” or Item B.G.01 in the SNBI. The data are also used to update the National Bridge Inventory File for the FHWA. Once a year the complete bridge inspection database for off- and onsystem bridges is converted to the Federal NBI format and submitted to the FHWA.
