Construction & Engineering Document Control

Reconstructing the Design History of 50,000 Engineering Drawings in a Construction Dispute

Legal and engineering teams used Docwize to bring order to more than 50,000 engineering drawings, transmittals, and approval records — transforming a fragmented project archive into a defensible chronology of revisions, approvals, and construction events.

50,000+ engineering drawings analysed

The full project drawing register was ingested, structured, and made analytically accessible within the platform.

Drawings linked to transmittals and approvals

Each drawing was connected to its associated transmittals, review comments, and approval records, enabling end-to-end traceability.

Approval timing mapped against construction

Overlaying approval dates with construction milestones revealed sequencing patterns material to the dispute.

Structured chronology for dispute proceedings

The analysis produced a defensible, document-backed sequence of events to support legal and expert teams.

The challenge

A major construction dispute required legal and engineering teams to reconstruct the full design history of a large infrastructure project. The underlying records — engineering drawings, transmittals, review comments, and approval documents — were fragmented across multiple sources and difficult to analyse at scale. Establishing a credible sequence of events required more than search: it required structured linkage across the entire project record.

The approach

Docwize ingested the full project document set and extracted metadata and revision history from each record. Drawings were linked to their transmittals, review comments, and approval records. Approval timing was then overlaid against construction milestones to identify where the sequence of events diverged from expected practice.

  • Ingest project drawings, transmittals, and associated correspondence
  • Extract metadata and revision history from each document
  • Link approvals, review comments, and distribution records
  • Compare revisions across cycles and annotate major design changes
  • Overlay approval timing with construction milestones to identify sequencing issues

What the analysis revealed

Extended approval timelines

Certain drawing packages remained in review significantly longer than expected, creating identifiable bottlenecks in the approval chain that could be traced through the document record.

Late-stage design changes

Major modifications between revision cycles were identified and placed in context — allowing the team to assess when changes were introduced and what approvals accompanied them.

Construction preceding sign-off

In several instances, drawings appear to have been approved only after related construction work had already progressed — a pattern that can materially affect delay analysis and dispute strategy.

Outcome

Docwize enabled the team to reconstruct the sequence of design decisions across a large, complex project record with a level of structure and traceability that manual review alone could not have produced at pace. The resulting chronology gave legal and engineering teams a shared, document-backed basis for analysing delay, assessing liability, and preparing for dispute proceedings.
