OVERVIEW
Ground Models You Can Build On
We build surface models from survey data and design levels, so grading, drainage and earthworks are planned with accurate quantities.
Surface scopes we cover:
Existing ground from survey
Proposed grading and platforms
Cut and fill and drainage falls

Why MANSYCOM
Since 2006, MANSYCOM has delivered BIM on airports, metro systems, campuses and towers up to 2M sq ft, for clients including L&T, Tata Projects and Kalpataru.
Our process follows PAS 1192, COBie and IFC, so surface modeling & drawings fits into the wider project from day one, not as a separate deliverable.
