Visual dependency mapping for flawless construction scheduling
Enterprise construction teams can't effectively schedule complex projects with subcontractors because current apps lack dependency mapping.
DepChain lets project managers create interactive dependency graphs for tasks and subcontractors, automatically calculating start/end dates and critical paths. It resolves conflicts in real-time as subcontractor availability changes. Export schedules to PDF/Gantt for stakeholder buy-in.
