About

Groma Plans

Read full description

Groma Plans puts your blueprints, takeoffs, and field markups in one place โ€” synced between the office and the crew on site. TAKEOFFS THAT STICK Linear, area, and count takeoffs tied directly to the sheet. Come back to a plan next week and your quantities are still there โ€” no rebuilding the notebook. COMPANY JOBS, REAL ROLES Invite your crew by email or join code. Everyone works off the same plan set, with role-based access for admins, estimators, foremen, and crew. ISSUES IN CONTEXT Track punch-list items and field notes directly on the drawing, with photos and voice notes attached โ€” so "circle the beam" means something the office can actually find later. BUILT FOR THE FIELD Large touch targets, offline-capable job access, and a viewer built for pinch-zoom and pan on a tablet in the sun โ€” not a shrunk-down desktop app. Groma Plans is sign-in only.
