Impact Intelligence for change orders
The Impact Intelligence Verification Graph Engine (VGE) maps change order dependencies across:
- Submittals, RFIs, and ASI revision chains
- Procurement lead times and installation sequencing
- Subcontractor scopes and trade coordination
- Critical path activities and schedule successors
Preview mode lets you model change order impact before field execution - with cost and schedule delta estimates across trades.
Submittal cascade analysis
See the full cascade before approving a change order:
- Submittal updates and RFI generation
- Subcontractor scope changes triggered
- ASI revisions and specification impacts
Schedule impact mapping
Understand critical path changes before committing to field work:
- Procurement and lead time effects
- Installation sequencing and successor activities
- Float consumption and milestone shifts
Multi-trade coordination
Identify conflicts across trades before mobilization:
- Cross-trade scope collisions (HVAC, electrical, plumbing)
- Spatial and sequencing conflicts
- Shared resource and access constraints

The problem
Scope changes cascade silently across trades
An HVAC design revision seems minor until you discover it affects 12 submittals, 4 RFIs, and 3 subcontractor scopes. When another change order introduces a collision, the compounding impact is only visible after field mobilization. By then, you're managing rework, schedule delays, and cost overruns.
Hidden cost of blind changes
- A mechanical design change triggers 8 downstream submittals and 2 ASIs with revised sketches, discovered only after subcontractor mobilization
- Material substitution approved without checking procurement lead times, causing a 4-week critical path delay and forcing schedule recovery
- Electrical scope change collides with plumbing rough-in, requiring demobilization and rework across 3 floors
- Permit condition change triggers 6 inspection hold points and re-inspections, delaying earned progress and affecting the current pay application draw approval
Key capabilities
Active intelligence for construction changes.
Submittal cascade analysis
Trace design revisions through submittal dependencies, shop drawings, product data sheets, and approval workflows. Identify all affected submittals, their current status, and re-approval requirements before issuing the change order.
RFI impact mapping
Map change orders to open RFIs, pending clarifications, and decision dependencies. Understand which RFIs are resolved, which require ASIs or supplemental sketches, and which introduce new clarification requirements.
Subcontractor scope propagation
Track scope changes across subcontractor agreements, work packages, and trade coordination. Identify affected subs, contract modification requirements, and multi-trade sequencing impacts before mobilization.
Schedule dependency checks
Analyze critical path impacts, successor activity delays, and milestone compression requirements. Preview schedule adjustments, float consumption, and liquidated damages exposure before approving scope changes.
Material procurement impact
Connect material substitutions to procurement lead times, supplier capacity, and installation sequencing. Identify long-lead items, supply chain risks, and inventory coordination requirements.
Cost-to-complete recalculation
Propagate scope changes through budget forecasts, contingency reserves, and cost-to-complete projections. Track change order accumulation, owner allowances, and GMP compliance in real time.
AIA billing alignment
Ensure change orders flow through AIA G702/G703 (or equivalent) payment applications, your schedule of values, and payment requisitions. Prevent billing mismatches, owner disputes, and draw rejections.
Permit and inspection triggers
Identify scope changes requiring permit amendments, additional inspections, or authority approvals. Preview permitting workflows, inspection hold requirements, and certificate of occupancy impacts.
How it works
From change signal to verified action.
Graph model for construction dependencies
EquatorOps builds a dependency graph of your project: change orders, submittals, RFIs, subcontractor scopes, schedule activities, procurement items, and AIA billing line items. Each entity and relationship is tracked in a unified graph structure.
Define impact rules for AEC workflows
Configure rules that match your project execution model: design revisions trigger submittal re-approvals, material substitutions check procurement lead times, scope changes validate subcontractor agreements, schedule accelerations analyze critical path float.
Preview cascades before approval
Before approving a change order, see the complete cascade: affected submittals, impacted RFIs, subcontractor modifications, critical path delays, procurement lead time risks, and billing adjustments. Understand the full project impact in seconds.
Detect multi-trade conflicts
When multiple change orders affect overlapping scopes, EquatorOps identifies collisions: mechanical changes conflicting with electrical rough-in, structural modifications affecting architectural finishes, plumbing revisions impacting fire protection.
Propagate approved changes
Once approved, Impact Intelligence surfaces the downstream updates: submittal statuses flagged for re-approval, RFI responses and ASIs queued, subcontractor notifications drafted, schedule adjustment recommendations generated, procurement lead time alerts raised, and AIA billing line item adjustments suggested.
Verification packs for field coordination
Generate verification packs for each change order: submittal re-approval checklist, RFI resolution confirmations, subcontractor scope acknowledgments, inspection hold requirements, material delivery confirmations.
Real-time coordination dashboard
Monitor project health across all trades: submittal approval velocity, RFI aging, subcontractor scope alignment, schedule critical path status, procurement on-time delivery, AIA billing reconciliation.
Hybrid graph model
The construction graph model captures the full lifecycle of scope changes: design revisions flow through submittals and shop drawings, material substitutions propagate through procurement and installation, schedule changes cascade through successor activities and trade sequencing. Each change order, submittal, RFI, subcontractor agreement, schedule activity, and billing line item becomes a node; dependencies become edges.
Submittal dependencies
Design revisions trigger submittal re-approvals, shop drawing updates, and product data revisions. Edges capture approval workflows, resubmittal requirements, and design coordination dependencies.
Trade coordination
Subcontractor scopes interconnect through rough-in sequencing, finish coordination, and MEP clash resolution. Edges track work package dependencies, mobilization sequencing, and multi-trade conflicts.
Schedule propagation
Schedule activities link through finish-to-start, start-to-start, and finish-to-finish relationships. Edges capture critical path logic, float consumption, and milestone compression impacts.

FAQ
Common questions about Impact Intelligence for construction.
How does Impact Intelligence handle multi-trade coordination?
EquatorOps tracks dependencies across mechanical, electrical, plumbing, fire protection, structural, and architectural scopes. When a change order affects one trade, the system identifies overlapping work packages, rough-in sequencing conflicts, and finish coordination requirements across all trades. You see multi-trade collisions before mobilization.
Can Impact Intelligence analyze schedule compression impacts?
Yes. When you accelerate the schedule, Impact Intelligence analyzes critical path compression, float consumption, trade overlap conflicts, subcontractor overtime requirements, and milestone recovery plans. You understand schedule compression risks before committing to aggressive timelines.
How does this integrate with AIA billing workflows?
Change orders flow through AIA G702/G703 (or equivalent) payment applications, schedule of values line items, and payment requisitions. When a scope change is approved, Impact Intelligence flags all affected SOV line items for adjustment, preventing payment application mismatches and owner disputes.
What about GC-subcontractor coordination?
Impact Intelligence tracks subcontractor agreements, work package scopes, and trade coordination requirements. When a change order affects a subcontractor scope, the system identifies contract modification requirements, mobilization impacts, and multi-trade sequencing adjustments. You coordinate with subs before issuing change notices.
How does Impact Intelligence handle field vs office coordination?
Verification packs bridge office approvals and field execution: submittal re-approval checklists for site teams, RFI resolution confirmations for trade foremen, inspection hold requirements for superintendents, material delivery schedules for logistics. Field teams receive actionable coordination documents, not just approval notices.
Can this preview permit and inspection impacts?
Absolutely. When a scope change requires permit amendments or additional inspections, Impact Intelligence identifies permitting workflows, inspection hold requirements, authority approval timelines, and certificate of occupancy impacts. You understand permitting risks before executing field work.
How does this prevent submittal cascade surprises?
Impact Intelligence maps design revisions to all affected submittals, shop drawings, product data sheets, and approval workflows. Before approving a change order, you see which submittals require re-approval, which are already in review, and which introduce new coordination requirements. No post-approval submittal surprises.
What about procurement lead time impacts?
Material substitutions automatically trigger procurement lead time analysis: supplier capacity checks, long-lead item identification, delivery schedule adjustments, and installation sequencing impacts. You understand supply chain risks before committing to material changes.
