Introduction

 The FLDCA (Field Logging Data Capture Application) project was developed to streamline field data collection for engineering teams. The goal was to replace paper-based workflows and outdated systems with a unified, tablet-based solution that reduces inefficiencies, minimizes errors, and improves data accuracy.

Highlights

 Value Delivered

  • 30–40% faster data processing by eliminating manual re-entry.

  • Improved accuracy and consistency of geological field data.

  • Reduced need for multiple devices with an all-in-one tablet solution.

  • Enabled Rock Mass Logging capability, previously unavailable in existing tools.

  • Increased transparency and efficiency through seamless CoreGS integration.

Challenges
 The existing data logging process faced multiple issues:

  • Manual workflows: Paper-based field notes required re-entry at the office, adding 10–40% extra time for transcription and error correction. 
  • Inefficient tools: Legacy systems such as CoreGS had a cumbersome GUI, leading to inconsistent and duplicate data. 
  • Bulky equipment: Engineers carried multiple devices to the field — paper or Toughbooks for notes, cameras for images, and GPS units for coordinates. 
  • Missing functionality: No capability existed for Rock Mass Logging, a key requirement for geological fieldwork. 

Solution
 The proposed tablet application provided an all-in-one, field-ready solution that enabled engineers to:

  • Complete all tasks on a single device in the field. 
  • Use an intuitive, touch-based interface for data entry. 
  • Operate fully offline when no internet connection was available. 
  • Integrate directly with CoreGS for seamless data transfer. 
  • Add dedicated Rock Mass Logging functionality.
