CHERP
Construction Hierarchy, Engagement & Resource Platform
Every other tool in construction pushes information down from the office — Procore, BIM360, SharePoint, all built for project managers. None reach the individual tradesman. CHERP builds the record from the bottom up — starting at the field worker and building upward to the foreman, the superintendent, and the office. The number that reaches the top finally reflects what happened on the ground. Accountability, both directions.
Core capabilities live today on web + Android · 14 trade profiles
Core flows are live today. A few areas are actively in progress or planned — we mark each one honestly.

Work Orders — assigned items with status and ownership
Hierarchy-aware assignment — superusers assign to anyone; foremen within their tree
Auto-aggregated daily record — compiled from tasks, MROs, JSAs, and timecards
Free-form narrative — plus snapshots of each source
Copy and PDF export
Material Request Orders — workers submit item + quantity; foremen/admin track fulfillment
Status workflow — Processing → Partial → Fulfilled, auto-notifications
Equipment and inventory tracking
JSA forms — trade-specific hazards, PPE, signature canvas; draft → submitted → approved
