The Little Patuxent Water Reclamation Plant treats wastewater for over 150,000 residents in Howard County. The county wanted a comprehensive solution to improve their asset management and field operation workflows. In partnership with Gannett Fleming, LandTech Consultants presented Howard County with an Esri ArcGIS solution to solve their challenges and an agreement was reached to launch a pilot project to evaluate the proposed solution for one of Howard County’s pipe gallery facilities.
LandTech completed the LIDAR scan and processed the data into a georeferenced point cloud using controls set during the survey. LandTech then used a processing tool to compare the point cloud to the design BIM to produce a full report, highlighting which elements were built within the 1” tolerance, and which elements were not. The design BIM was converted to an accurate, as-built BIM model, and 2D CAD plans were developed for additional documentation.
Howard County was impressed with the digital twin solution and the enterprise-wide value it provided as a central digital repository that’s accessible in the office or remotely. They plan to create a digital twin for their entire facility and integrate it with their asset management platform in the near future. Additionally, they are looking to integrate their campus’ horizontal assets with these 3D models to give a holistic view of all their assets both inside their facilities and the subsurface utilities.

plan smarter and manage assets more effectively.
