From Disconnected 2D Drawings to Integrated 5D BIM
How a contractor transformed separate AutoCAD drawings, SketchUp models, schedules, and cost spreadsheets into one coordinated BIM workflow.
Company Background
A national mid-to-large building contractor delivering commercial, healthcare, residential, and industrial projects. The company has strong field execution capability, but its preconstruction and project-control teams still depend heavily on 2D drawings, spreadsheets, manual quantity calculations, and separate planning tools.
Business Snapshot
- •+850 employees
- •+IDR 3.6T annual revenue
- •10–14 active projects per year
- •Average project value +IDR 300B–1.2T
- •Main services: general contracting, design coordination, procurement, and construction delivery
Primary Business Needs
- •Convert 2D drawings into coordinated BIM models
- •Improve quantity take-off accuracy for tender and procurement
- •Connect model information with schedule and cost planning
- •Identify clashes before construction work starts
- •Create clearer visibility over project budget, scope, and timeline
CHALLENGE
Project information was scattered across AutoCAD, SketchUp, spreadsheets, and scheduling tools. This caused inconsistent revisions, repeated quantity calculations, late clash detection, and inaccurate tender cost estimates.
SOLUTION
BIMAGE implemented an integrated 2D–5D BIM workflow, connecting coordinated BIM models with clash detection, quantity take-off, construction schedules, and project costs.
RESULT
Quantities and costs could be calculated more accurately, helping the contractor prepare more competitive tender proposals, identify clashes earlier, and gain clearer visibility into project schedules and budgets.
