Contractor Schedule Review — An Eight-Gate Assurance Process
A controlled workflow for baseline schedules, updates, revisions and recovery plans—from formal receipt to an auditable disposition.
A contractor schedule should be more than a compliant file. It must be a credible model of scope, sequence, interfaces, resources, contractual obligations and forecast outcomes. Review quality depends on clear gates, traceable findings and disciplined version control.
01 · Required Submission
Review The Schedule And Its Basis Together
Native Schedule File
Complete native export with project settings, calendars, coding, resources, costs and user-defined fields as contractually required.
Schedule Narrative
Basis, scope, methodology, assumptions, calendars, logic strategy, constraints, resources, critical path and changes.
Supporting Evidence
Milestone register, coding dictionary, procurement plan, design and approval registers, resource plan, cash flow and quality-check reports.
02 · Eight Decision Gates
Separate Each Review Question
Receive And Log
Record submission type, revision, data date, files, transmittal, contractual due date and chain of custody; acknowledge receipt without implying acceptance.
Completeness And Format
Check mandatory files, readable native data, required fields, naming, coding, reports and preliminary thresholds. Return incomplete submissions promptly.
Technical Quality
Assess logic, open ends, constraints, lags, calendars, durations, float, critical path, progress, resources, costs and model integrity.
Technical Feasibility
Coordinate design, construction, procurement, commissioning, operations and other specialists to test sequence, access, production and interfaces.
Contract Compliance
Trace milestones, sectional completion, deliverables, reporting rules, calendars, possession, approvals and required methodology to contract clauses.
Impact And Forecast
Compare with the approved baseline or prior accepted update; explain variance, path change, delay, recovery, cost, resource and risk consequences.
Findings And Resolution
Classify findings by materiality, cite activities and evidence, obtain contractor responses, record agreements and preserve unresolved positions.
Formal Disposition
Issue the authorized decision, conditions and resubmission requirements; update controlled systems and archive every reviewed version and record.
03 · Schedule Quality
Test Whether The Model Can Support Control
- Scope and contractual milestones are complete and traceable to deliverables.
- Activities use appropriate calendars, durations and measurable completion criteria.
- Logic is complete; open ends, excessive lags and preferential constraints are justified.
- The critical and near-critical paths are continuous, plausible and explained.
- Total and free float values are understood and not distorted by hidden settings or constraints.
- Resources, productivity, procurement and approval assumptions support the planned sequence.
- Cost and resource loading reconcile with agreed control accounts where required.
- For updates, actual dates, remaining durations, out-of-sequence progress and data date are validated.
- Changes from the prior version are identified, explained and authorized where necessary.
04 · Submission Type
Apply The Correct Review Lens
Baseline Schedule
Test completeness, contract alignment, feasibility, control structure, resource basis and whether it forms a credible performance reference.
Periodic Update
Validate actual progress, current logic, forecast, variance, path migration, risks, changes and corrective actions.
Revised Baseline
Require authority and maintain traceability to the original baseline, approved changes and reasons for rebaselining.
Recovery Schedule
Test whether acceleration or resequencing is feasible, resourced, safe, contractually coherent and measurable.
Time-Impact Submission
Validate status, selected update, fragnet logic, event evidence, assumptions, contemporaneous intent and modeled effect.
What-If Scenario
Keep analytical scenarios separate from controlled schedules unless and until formally approved.
05 · Findings And Disposition
Make Every Comment Actionable And Traceable
Each material finding should identify the schedule version, activity or field, requirement or evaluation basis, evidence, consequence, requested correction, responsible party and response status. Distinguish observations, required corrections, contractual non-compliances, assumptions and management risks.
06 · Proportional Assurance
Increase Review Depth Where Exposure Is Highest
Review effort should reflect contractual significance, project complexity, submission quality, schedule change, current delay, recovery pressure and decision risk. Automated quality metrics are useful screening evidence, but no score replaces technical review of scope, sequence, constructability and actual project conditions.
Management Conclusion
A Good Review Protects Both Control And Accountability
The schedule-review process should produce more than comments. It should establish a traceable record of what was submitted, what was tested, what remains uncertain, what must change and who holds the formal decision—while preserving the contractor’s responsibility for its plan and performance.
