Precise LOD 400 BIM and Coordination for a 1.4 million sq. ft. High-Rise

Key Challenges

• Managing the vast project scale across 30+ floors, requiring high attention to detail in space planning and element placement.

• Ensuring clash-free integration of architectural, structural, and MEP elements, particularly for ceiling-based MEP systems.

• Coordinating evolving inputs from multiple consultants while maintaining version control and timely model updates.

• Meeting documentation standards for DD and GFC packages in compliance with U.S. codes and local jurisdiction requirements.

Approaches and Solutions

• The architectural team developed a comprehensive site model including roads and boundary walls using initial SD inputs.

• Leveraging Revit and Navisworks, ceiling-level MEP components were modeled with precise level and location definitions.

• Regular BIM coordination meetings and clash detection using Navisworks ensured early conflict resolution and design alignment.

• Quantity Take-Off (QTO) sheets were generated directly from the LOD 400 model to assist with estimation and material planning.

• Continuous integration of consultant inputs was facilitated via shared CDE platforms, ensuring consistency and transparency.

• Final DD and GFC sets were developed in Revit and exported as detailed PDFs in line with the NYC Building Code and applicable standards.
