Use Case
Datagrid's Document Comparison Agent compares drawing revisions, flags scope changes, and verifies civil risk elements across baseline and revised sets for faster review and change management, without manual PDF overlay workflows.
Baseline drawings in one folder. Revised sets in another. Specs in email attachments. Every revision cycle, project managers manually overlay PDFs, scan for differences sheet by sheet, and hope they catch the grade change on C-401 before it becomes a costly change order.
Design deviations account for a large share of rework cost. Each undetected revision change compounds, generating RFIs and triggering change orders that can increase contract price.
The Document Comparison Agent is an AI agent that analyzes differences between drawing sets to identify material changes that may impact scope, cost, schedule, or constructability. Project managers still interpret results and direct responses, but the AI agent removes the manual sheet-by-sheet overlay that consumes hours per revision cycle.
The AI agent receives both the baseline and revised civil drawing sets, including plan sheets, details, sections, and material callouts. Both versions must be provided.
The AI agent compares drawing sets and identifies material changes in high-risk civil elements: grades, flatwork, roadwork, utilities, materials, and key dimensions. It filters out minor administrative or annotation changes, including title block updates, date stamps, and cloud markups, so project managers review what affects scope and constructability.
The AI agent contextualizes each detected change by showing what changed, where it changed, and why it matters from an owner and project management perspective. It flags scope creep between Issued for Tender and Issued for Construction sets, highlights field risks that affect constructability, and identifies compliance gaps when comparing submittals against specifications.
The AI agent assembles structured change documentation that feeds directly into cost tracking discussions and change management workflows. Instead of a raw markup overlay, project managers receive identified material changes organized by risk category, ready for review meetings and follow-up action.
Civil drawing sets (baseline and revised) including plan sheets, details, and sections
Material callouts and specifications referenced in drawings
Specifications documents for compliance cross-checking
RFIs and submittals for gap identification against project requirements
Identification of material changes between drawing sets with location and impact context
Scope creep detection between drawing revisions, flagging what shifted between tender and construction phases
High-risk civil elements flagged: grade changes, utility relocations, flatwork modifications, material substitutions, dimension shifts
Constructability and field risks highlighted before construction starts
Change documentation structured for cost tracking discussions and change management review
The Document Comparison Agent operates within a broader revision management workflow. It connects directly to procurement workflows when material callouts shift between revisions. It feeds RFI generation workflows when conflicts between drawing versions produce grounded questions for resolution. It informs schedule monitoring when early scope changes trigger re-sequencing conversations before field delays spread. The AI agent also cross-checks submittals against specifications to identify compliance gaps before materials arrive on site. Cost tracking, subcontractor coordination, and review meetings all depend on accurate, current information about what changed between revision sets.
The Document Comparison Agent connects to your existing construction management stack without custom integration work, keeping revision review inside the systems teams already use.
Procore
Connects drawing revision workflows to flagged civil scope changes so project managers and field teams can review updated sheets without switching systems.
SharePoint
Connects baseline and revised drawing files stored in shared document libraries for comparison from controlled document sets.
Autodesk Construction Cloud
Connects hosted plan set workflows where revision comparisons surface civil drawing changes before coordination issues spread.
Oracle Aconex
Connects formal document control workflows where revision-driven scope changes need visibility through transmittal, review, and approval.
Slack
Routes visibility when material drawing changes, scope creep, and compliance gaps need to reach the right team quickly.
Keeping these systems synced moves teams faster from detected drawing changes to coordinated review, change management, and downstream action.
The AI agent compares Issued for Tender drawings against Issued for Construction drawings and flags material changes in civil elements: grades, utilities, flatwork, roadwork, materials, and key dimensions. Each flagged change includes what shifted, where on the drawing it occurred, and why it matters for scope and cost. Project managers receive this documentation before construction starts, not after a subcontractor discovers the discrepancy in the field.
No. The AI agent executes the comparison and detection work, including sheet-by-sheet overlay review, cross-referencing of material callouts, and identification of dimensional shifts. Project managers interpret the flagged changes, decide which require action, and direct the response. The AI agent turns a manual review into a structured exceptions list that a PM can evaluate more efficiently.
The AI agent compares submittals against specifications and identifies compliance gaps, including cases where submitted materials, methods, or details diverge from specification requirements. It grounds its analysis in the project requirements documented in the specs, so gaps are identified against the actual standard rather than generic assumptions. This catches mismatches before materials are fabricated or delivered to site.
The AI agent focuses on high-risk civil elements: grades, flatwork, roadwork, utilities, materials, and key dimensions. It filters out minor administrative or annotation changes. A revised title block date or a repositioned cloud markup does not surface in the comparison output. A shifted utility alignment or a modified material specification does.
The AI agent compares any two provided drawing sets: baseline against first revision, first revision against second, or original tender set against final construction issue. Each comparison requires both the baseline and revised sets as inputs. For projects with multiple revision cycles, project teams run sequential comparisons to track how scope has evolved across the full revision history and build a documented trail for change management and cost tracking.
Datagrid turns drawing revisions into structured change insight before missed updates become cost and schedule problems.
