Construction Change Order Analysis & Documentation
Analyze construction change orders for scope, cost, and schedule impact with professional documen...
What You Can Do
You can submit change order requests—whether verbal or written—and receive a structured analysis that identifies exactly what's changing, why it costs what it costs, and when it will be completed. Claude breaks down costs by labor, materials, equipment, and overhead, assesses schedule impact including critical path dependencies, and generates defensible documentation packages for stakeholder communication and claims protection. This prevents the inadequate documentation that typically originates construction disputes.
Features
systematically evaluates scope, cost, and schedule dimensions in a single framework to ensure no impact is overlooked
distinguishes labor, materials, equipment, and overhead costs with line-item justification for defensibility
identifies how changes affect project timeline and identifies dependencies that could cascade delays
generates formal change order writeups, communication templates, and supporting exhibits ready for stakeholder review
monitors and documents the combined effect of multiple changes across the project lifecycle
provides owner, general contractor, and subcontractor-specific messaging to align expectations and reduce disputes
flags potential disputes, claim triggers, and contractual complications before changes are approved
structures analysis to support future cost or schedule claims with clear cause-and-effect documentation
Example Output
Example 1: Unforeseen Foundation Condition
Submitted Request: "Contractor discovered unstable soil at footing depth; needs 4-day delay and $18,500 additional excavation/shoring work"
Claude Analysis Output:
- Scope Change: Removal of 240 CY of unsuitable soil; installation of 1,200 SF of temporary shoring
- Cost Breakdown: Labor (4 operators × 4 days): $3,200 | Shoring materials & rental: $9,800 | Equipment (excavator + compressor): $4,200 | Contingency: $1,300
- Schedule Impact: 4-day critical path delay; no concurrent activities to absorb
- Documentation: Change order with soil condition photos, engineer memo, cost quotes from three suppliers (two highlighted)
- Recommendation: APPROVE with owner notice; document unforeseen condition in writing before work begins
Example 2: Design Change During Construction
Submitted Request: "Owner requests upgraded mechanical system; architect is finalizing specifications"
Claude Analysis Output:
- Scope Change: Replace baseline HVAC system with high-efficiency unit; adds 40 hours design coordination
- Cost Breakdown: Equipment premium: $12,500 | Additional labor (40 hrs × $85/hr): $3,400 | Extended commissioning: $2,100
- Schedule Impact: 2-week delay pending final specs; 3-day installation impact if on critical path
- Documentation: Draft change order with equipment cut sheets, phased approval process, contingency schedule
- Risk Flags: Design delay could impact GC schedule; recommend owner approval gate by specific date
- Recommendation: REQUEST CONDITIONAL APPROVAL pending specifications; set firm date for design release to avoid cascade delays
