About this app

Katchap is construction management software built on-site. On a live project, the record is scattered — inboxes, chats, paper logs, loose photos, old drawing revisions and shared folders nobody fully trusts — and every question turns into a search.

In Katchap, the floor plan is the project. Upload a drawing, add your spaces and services, and the day-to-day site work is anchored right where it happens: spatial progress by space, service and trade; observations and held-ups that pulse on the plan room by room; inspections anchored to the floor plan from finding to fix; and 360° space capture set out on the drawing.

Around that, the formal workflows stay part of the same controlled record, so nothing lives in a silo: RFIs with threaded, version-controlled Q&A, SLA tracking and routing; submittals with multi-stage approvals, stamps, comments and revisions; documents in an eight-stage record with folder permissions and approvals; a site diary for the daily record of conditions, trades, plant and evidence; and analytics showing Progress, Observations and Held Up at a glance.

Main contractors, PMs, subcontractors and consultants share one project truth, filtered by role and permission. Made on the site, for the site.
