Data Management Guide Specification for Basic Grouting Projects-PDF

PDF
Pdf Summary
The September 2024 DFI Data Management Guide Specification for Basic Grouting Projects sets out requirements for collecting, organizing, quality-checking, submitting, and visualizing data from grouting and water-testing operations. Owners may use it as a standalone specification or as an addendum to DFI’s broader data management guide; project-specific formats and requirements should be agreed before work begins.<br /><br />Contractors must submit new and modified data at the end of each workday. Required project-element data include grout-hole identifiers, locations, dimensions, orientation, elevations, depths, and deviation measurements where applicable. Stage records must identify the related hole and stage, depths, length, completion time, and notable conditions. Water-test and grout records include duration, Lugeon value, and injected volume, as applicable. Time-series monitoring data must include timestamps, stage IDs, flow, pressures, Lugeon measures, and raw sensor readings.<br /><br />Data must be provided in accessible, clearly labeled formats, such as ASCII/CSV, Excel, a relational database, or an industry-standard format such as DIGGS. Contractors must supply relevant units, calculation methods, and data-generation criteria, and provide files through an agreed secure transfer site or shared drive. Any required conversion or software is the Contractor’s responsibility.<br /><br />Contractors must verify field data, review and correct errors, and record quality-control information. They must also provide visualizations updated at least weekly, showing project progress, grout volumes along boreholes, and water pressures or Lugeon values. Acceptable products include CAD or GIS drawings, PDFs, or a web-based dashboard, subject to Owner acceptance.
