| Abstract | Typically, the practice of recording as-built conditions during construction involves marking up paper or electronic portable document file (PDF) plan sheets. The purpose of the marked-up plans is to have a permanent record of what is built and accepted during the construction project. This information is kept in electronic or physical cabinets and later used to extract asset data for routine maintenance activities. However, with the advent of geospatial technologies such as light detection and ranging (LiDAR), Global Navigation Satellite Systems (GNSS), and geographic information systems (GIS), some States are collecting data after construction—using these technologies to populate asset management GIS databases. The challenge with this approach is that only data on the assets visible above ground is collected. Another approach to capturing information on as-built conditions is to enable construction staff to collect asset data using geospatial tools as they accept the work being installed. The advantages of collecting asset information during construction are that maintenance workers do not need to return after the work is completed to collect the information, and the location and conditions of installed underground and aboveground assets are captured all at once. Collecting as-built information on assets during construction is exactly what the Minnesota Department of Transportation (MnDOT) and the Iowa Department of Transportation (Iowa DOT) have set out to accomplish. |
