Asset Management
Description
The City of Belle Meade, a satellite city within Davidson County, contracted LDA Engineering to conduct an asset inventory, condition assessment, GPS location of sewer assets, and to develop an asset management plan. GPS survey included all gravity sewer features, force main lines, and grinder pump stations in their jurisdiction using TDEC DWR-ARP-SWIG funding and completed delivery within critical grant timelines. The Asset Management inventory included over 900 grinder pumps and 65 miles of sewer lines. The city was operating with a legacy system of hard-copy archived drawings and low confidence in data accuracy. LDA used ground penetrating radar (GPR) to locate over 65 miles of force main lines, Carlson GPS units to collect sub-centimeter geospatial data of all sewer assets, and ESRI’s GIS suite to collect and create a comprehensive digital representation of the sewer network. Through the data collection effort, LDA created a feature-rich dataset to be the baseline for managing the entire sewer system. LDA assisted with the procurement of an advanced work order system and prepared an Asset Management Plan (AMP) to achieve this. LDA utilized innovative technology to streamline data collection and geospatial data integration including Field-to-Finish, Field Maps, RD8200 GPR, BRx7 GPS, and cloud-hosted webmaps and dashboards syncing office and field work in real time. LDA’s work added value to the City of Belle Meade throughout their entire department. They received an engineering condition assessment of the sewer system, increased confidence in their asset metadata, a geodatabase of each of their assets, a work order system streamlining communication between office and field staff, and a comprehensive digital representation of the entire sewer system. These deliverables provided value and cost savings to the city by expanding and informing their spatial understanding, asset maintenance, data analysis, accessibility and collaboration, public awareness, historical tracking, decision-making, budget planning, and asset lifecycle/replacement planning.
