DIGGS Scheme for Rock Grouting Data Transfer-PPT Presentation

PPT Presentation

Pdf Summary

The DIGGS rock grouting extension adds construction data to the established open-source geotechnical data standard. Developed over roughly 20 years with support from DOT and FHWA, DIGGS was originally designed mainly for geotechnical data such as borings. The Deep Foundations Institute funded this project to integrate construction technologies, beginning with rock grouting.<br /><br />The extension aims to document the full workflow, including geotechnical background, grout-hole locations, drilling and measurement-while-drilling data, packer setting and water testing, grout injection and mix properties, and closure tests. A shared data structure can reduce paper-based capture, repeated data conversion, and errors by allowing information to be entered once and transferred among field, analysis, design, and asset-management systems.<br /><br />Development included four online workshops to review data forms, databases, workflows, and existing DIGGS capabilities. The schema adds a construction-activity structure and a LinearGroutingActivity feature. It also extends borehole backfill and casing information, including backfill type and volume, links to grouting activities and grout batches, grout ports, installation and removal times, and casing advancement details.<br /><br />The standard is intended to let data producers and consumers choose their preferred software and storage systems while exchanging information in a consistent format.<br /><br />Planned expansion includes draft schemas for compaction grouting, jet grouting, and soil mixing. These add a “Program” object for comparing specifications with completed construction and extend objects for grout-related equipment and tests. Other potential areas include optical televiewers, geophysics, measurement while drilling, instrumentation, pile driving, validation tools and APIs, training, and public access to open data.
