AI Construction Cost Report Agent

Automating Construction Cost Report Generation with AI
Unified budget-to-actuals reconciliation
The agent automatically ingests actuals from ERP systems, matches invoices to commitments and budget lines, computes accruals, and normalizes everything to your WBS/CBS structure—eliminating manual spreadsheet consolidation.
Intelligent variance analysis and forecasting
AI-driven diagnostics attribute variances by quantity, rate, and timing while generating EAC/ETC projections using blended methods—commitment-driven for subcontracted scope, CPI-based for self-performed work, and bottoms-up where known changes exist.
Automated report generation with audit trails
The system produces complete monthly cost report packages—budget vs. actuals tables, S-curves, change order logs, and executive summaries—with immutable snapshots, version control, and approval workflows built in.
How Cassidy automates monthly cost reporting using AI
Step 1: Trigger on period close
The Workflow activates automatically at your defined monthly cut-off date, or can be triggered manually when your team is ready to generate reports.
Step 2: Ingest and reconcile financial data
Cassidy pulls actuals from your ERP, invoices from accounts payable, and progress updates from your schedule system (P6, MSP). It matches transactions to commitments and budget lines, flags goods-received items needing accruals, and normalizes all data to your WBS/CBS hierarchy.
Step 3: Analyze variances and compute forecasts
Using your Knowledge Base—which contains budget baselines, commitment registers, and change order logs—Cassidy calculates budget vs. actuals variances by cost code, attributes drivers (quantity, rate, timing), and generates EAC/ETC using your preferred methodology: commitment-driven, CPI-based, or hybrid.
Step 4: Generate the cost report package
Cassidy assembles the complete monthly deliverable: executive summary with KPIs (CPI, SPI, VAC, contingency status), detailed budget vs. actuals by WBS/CBS with variance narratives, EAC/ETC rollups, commitment and accruals registers, change order logs with exposure quantification, and time-phased S-curves.
Step 5: Route for review and distribute
The Workflow sends the draft report to designated reviewers via Slack or Teams with Human-in-the-Loop approval. Once approved, Cassidy locks the monthly snapshot, maintains the audit trail, and distributes the final package to stakeholders—project managers, executives, and owners—through your preferred channels.
