In geotechnical engineering and the underground construction industry, a significant amount of data is collected for a wide variety of projects. The current management, storage, and transfer of this data is both time consuming and expensive, and often results in the use of manual entry and re-entry of data multiple times. The manual entry of data into various database, analytical programs, or between entities can result in errors or loss of information over multiple iterations. To reduce the need for manual reentry of data, and subsequently reduce errors in data transfer and time, the Geo-Institute of the American Society of Civil Engineers is in the process of finalizing DIGGS (Data Interchange for Geotechnical and Geoenvironmental Specialists), a standardized format for saving data in XML files that can be used to store and transfer data between programs and databases. Initially, the DIGGS schemas were developed to contain geotechnical investigation data and rock grouting project data, however, there is a need for the schema to include all underground construction activities. As a result, a project to include soil permeation and compaction grouting was approved by the Geo-Institute Special Projects Committee. This thesis discusses the procedure used to modify the DIGGS file formats to include soil and permeation grouting, explain the changes made to the schema, assess the effectiveness of the changes made by applying DIGGS to real project data, and review the future developments needed to further modify and expand DIGGS for use on soil grouting projects. The updates completed as part of this project successfully integrated permeation and compaction grouting into DIGGS while also preparing the schemas for future modification as other types of grouting and underground construction projects are added into DIGGS. A major addition to DIGGS as a result of this work was adding a new top-level class of features for additional program level information that can be cross-referenced with various construction activities. This latest contribution, while still in the early stages of development at the time of writing this thesis, is a major re-envisioning of what DIGGS can be used for and taking it from capturing geotechnical data in linear elements primarily focused on geotechnical exploration (borings, cone soundings, test pits, and in-situ and laboratory testing) to multi-dimensional and can capture design versus construction data and cross-reference to specifications
