Data Drives Herbert Hoover Dike (HHD) Rehabilitation Efforts-Paper

Paper

Pdf Summary

The Herbert Hoover Dike rehabilitation project required 17.6 miles of seepage cutoff wall across three task orders. With up to ten rigs operating simultaneously and more than 45,000 construction elements to track, the contractor developed a project management information system (PMIS) to manage production, quality control, documentation, and reporting.<br /><br />The system’s core, the in-house b-project application, combines design and as-built records with rig telemetry, field observations, laboratory tests, and other quality-control data. Data engineers check and structure raw telemetry, then compare as-built information against design criteria. Automated checks flag discrepancies, while production reports and dashboards help teams assess panel geometry, overlap, productivity, and quality. Data also feeds a GIS with searchable plan and 3D views, linked records, photographs, and test results. Cloud storage, secure client access, and backup procedures support data availability and recovery.<br /><br />Web dashboards provide project teams and the USACE with access to performance indicators and activity records, including weather, equipment breakdowns, and material delays. These tools help identify quality concerns, data-entry errors, production trends, and opportunities to improve efficiency.<br /><br />The team’s lessons included the importance of timely communication, regular coordination meetings, and tailoring dashboards to field managers’ needs. Mobile data-entry tools required close observation of field operations, and changing workloads made flexible, collaborative staffing necessary.<br /><br />Overall, the digital workflow enabled faster responses to errors and quality issues, improved production monitoring, and more efficient data delivery. The authors conclude that robust data capture and management are essential for both meeting client reporting requirements and supporting effective project decisions.
