AIRFIELD MAINTENANCE By Tim Fredlund and Tim Lee Mapping Technology Eases Airfield Asset Management Get an accurate assessment of your as built data now to create a better plan for the future. Managing utility, lighting and communication assets on the airfield is becoming a popular way to stretch the limited capital resources dedicated to the upkeep and operations of United States airports, especially those with a large geographic footprint. In an economic climate where time equals money, having a reliable, single set of data that shows the location of an airfield's lights and signs, utility cables, manholes, handholes and circuits saves maintenance investigation time in the field and engineers' time in designing improvements and repairs. Having this data also helps airports that use consultants for capital improvement projects. In developing designs and project solutions, consultants must adhere to a specific set of airport standards. By providing airport consultants with a single set of data to work from, the airport can help ensure that the end-products will be uniform and can easily expand the data with each new project. The Federal Aviation Administration Advisory Circulars require that federally obligated airports develop and keep accurate as-built data and recommend all airports do the same. However, some airports have recently gone one step further and undertaken a full utility inventory project. Taking the time to create an accurate "snapshot" of the system as it exists today can give an airport a chance to have a place to build from for future improvements and a baseline to troubleshoot future problems. "If you don't know exactly how circuits are routed or which circuit is which in a manhole, you could spend days trying to figure it out. That kind of time can directly impact operations," said Tim Lee, P.E., senior electrical engineer at Pond, an architectural, engineering, planning and construction firm based in Atlanta. Full utility inventories produce data that can be recorded on paper, in Excel, or even published in Geographic Information Systems (GIS). Many airports undergoing this type of data inventory may opt for GIS, since the program is easy for airfield maintenance crews to access on mobile devices in the field. However, some airports may also wish to develop a more interactive and robust electronic tool for airport operations and future design purposes. Hartsfield-Jackson Atlanta International Airport (ATL), the world's most traveled aiport, recently underwent a full utility inventory that included the documentation of their entire airfield lighting and signage system infrastructure, electrical distribution system, communications system, duct banks, manholes, handholes, and pullcans. ATL's main goal for the inventory was to create accurate AutoCAD files for both internal and external engineers to use when putting together design packages, but the airport also wanted the data delivered in a way that could be pushed out into both Excel spreadsheets and GIS. Additionally, ATL wanted the inventory data in an electronic format that could render interactive images of the cable lines and With AUD, the consultant team was able to render the data into images that offered clickable links to information and, because of the program's compatibility to Autodesk's Civil3D, they also were able to render the data into 3D images rather than 2D.
