Use of Geospatial Project Information Management Systems on Diaphragm and Secant Pile WallsÂ-PPT Presentation

PPT Presentation

Pdf Summary

The presentation describes the growing use of geospatial Project Information Management Systems (PIMS) on diaphragm and secant pile wall projects. As projects become more digitalized, owner specifications—including USACE and DFI guidance—are increasingly requiring structured systems for managing construction information.<br /><br />The specifications aim to collect reliable digital data efficiently, give owners access to information during construction, preserve a documented archive afterward, and present project data in a shared geospatial context. Relevant information may include borings, wall elements, quality-control records, and photos.<br /><br />A PIMS should include an owner-accessible enterprise relational database, GIS mapping tools, and web-based viewers alongside editable desktop files. It should support plan, profile, and 3D views; automatically generated reports for each secondary wall element; and progress and as-built drawings. Element reports should show calculated positions and overlaps with adjacent elements at multiple depths, including in profile view.<br /><br />Reports and drawings may be submitted as standalone files, such as PDFs and CAD files, but should ideally be generated directly from the database. Drawings should depict the continuous wall and its overlaps at multiple depth intervals. Dashboards provide a single web-based entry point to the database, GIS, reports, drawings, documents, photographs, pay items, and schedule information.
