Solution
Like many utilities nationwide, this utility has launched a comprehensive telecommunications system upgrade to accommodate a host of new demands. Burns & McDonnell was contracted to provide design support for the network upgrade, and for which new design work would occur at almost all telecom equipment locations, including all major substation, generation and office locations. It was a perfect time to modernize the telecom group’s documentation system.
After trial and analysis, a customized ArcGIS Pro system was selected to form the primary system of record for telecom system site design and equipment interconnectivity. ArcGIS Pro offered the ability to track equipment assets and interconnectivity in a single view, enhancing geographic awareness of assets, along with industry and utility adoption. It delivers the power of a back-end database for bulk updates and data analysis. Esri’s ArcGIS software is a geographic information system for working with maps and geographic information. Although ArcGIS is essentially a geospatial program, its database support and two-dimensional layout functionality allowed the development of telecommunications network one-line diagrams approximating legacy Visio and CAD diagrams, as well as support for other key assets of interest such as building and facility site layouts. This gives engineering designers and O&M staff the ability to utilize a database in which they can access a single source of trusted information for equipment wiring and connectivity.
The ArcGIS Pro system has not been utilized exclusively, however, and its use has been complemented with certain CAD drawings. These CAD drawings were updated to utilize new standard naming conventions and a standard border with defined data fields to support integration and automation with the Vault drawing management system, providing consistency with standards being utilized by the substation and generation groups.
The file conversion process to migrate from MicroStation to AutoCAD for CAD files to match the substation group standards required creation of a script file based on LISP programming incorporated into AutoCAD. This automation programming enabled economical reformatting of the legacy drawings with the click of a button. The output was a drawing with a new title block and up-to-date layers preserving the aesthetics of the original drawing content, with minimal need for manual updates of the files. The process enabled a seamless and labor-efficient process to convert large batches of legacy drawings to the new file format.
