Engineering DMS Metadata Remediation & Trust Restoration

When a system migration stripped critical metadata from 146,000 engineering records, Waterline restored accuracy, findability, searchability and operational trust at scale. Read more…

Metadata Remediation & Trust Restoration at South Walker Creek Mine

As part of a digital transformation initiative, South Walker Creek Mine migrated its engineering drawings into a new Document Management System (DMS).

While the files transferred successfully, critical drawing metadata did not. Titles were missing, revisions were unclear, and thousands of non-drawing artefacts were mixed into the live engineering environment.

Engineers could no longer rely on search results. Drawings had to be manually opened and checked before use, slowing productivity and increasing the risk of referencing incorrect or superseded documents.

With over 146,000 artefacts in the system, manual cleanup was not feasible. Confidence in the new DMS was rapidly declining.

Waterline treated the issue as a trust restoration challenge, not just a data clean-up task.

We deployed a hybrid approach combining proprietary automated metadata extraction with engineering-led verification.

Our process included:

Automated extraction of drawing numbers, titles and revisions at scale
Structured validation rules to ensure high-confidence results
Segregation and quarantine of non-drawing artefacts (no deletions without client approval)
Human-in-the-loop review for complex or low-confidence files

This approach ensured governance, transparency and full client control while restoring metadata accuracy across the system.

Waterline processed 88,000 files, identifying and remediating 46,000 legitimate engineering drawings.

Eighty-eight percent of drawings were restored with accurate, searchable titles, significantly improving system usability and reducing time spent locating critical information.

Non-drawing artefacts were classified and quarantined to protect data integrity, lowering the risk of incorrect or invalid documents being used in operations.

The result was a measurable uplift in searchability, governance and reliability, restoring confidence in the DMS as a trusted operational system, without disrupting site activities.

“After migrating to our Engineering Drawing Management System (DMS), our engineers and coordinators couldn’t find the drawings they were searching for. Waterline reviewed our current state, re-processed all our drawings, removed duplicates and populated the metadata fields for all the drawings. We found that 88% of the existing system metadata was generic and unsearchable. We are now at close to 100% metadata extracted from our drawings. This rebuilt confidence in the system without compromising governance. Our DMS is now a system our technical personnel on site can rely on again.”—Electrical Engineering Manager, South Walker Creek

Challenges Faced During Metadata Loss

The migration of engineering records at South Walker Creek Mine presented significant challenges, particularly due to the extensive metadata loss. Missing titles and unclear revisions complicated the identification and retrieval of critical documents, impacting operational efficiency.

As a result, thousands of non-drawing artifacts were inadvertently mixed into the live engineering environment, which posed risks to data integrity and governance. Addressing these challenges required a meticulous approach to ensure that the restoration process did not disrupt ongoing site activities.

Our Proven Methodology for Metadata Restoration

Waterline Projects employs a structured methodology for metadata restoration that emphasizes accuracy and client collaboration. Our process begins with the automated extraction of essential drawing information, followed by the application of structured validation rules to ensure high-confidence results.

This approach is complemented by a human-in-the-loop review for complex files, ensuring that all decisions are made with the utmost care. By segregating and quarantining non-drawing artifacts, we maintain governance and transparency throughout the project, allowing clients to retain control over the process.

Impact on Operational Efficiency

The successful restoration of metadata at South Walker Creek Mine has led to a significant improvement in operational efficiency. With 88% of drawings restored with accurate, searchable titles, users can now locate critical information more quickly and effectively.

This enhancement not only boosts system usability but also reduces the time spent on searching for documents, ultimately leading to a more reliable and trusted document management system. The measurable uplift in searchability and governance has restored confidence in the DMS as an integral operational tool.
