Surface Modeling

Ground Models You Can Build On

Building Wireframe Design
Engineer Reviewing Blueprint

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 ISO 19650, PAS 1192, COBie and IFC, so surface modeling & drawings fits into the wider project from day one, not as a separate deliverable.
