In 511,779 square feet of multi-residential building design, BIM Services provided mechanical BIM modeling, shop drawings, and coordination services for The Modern. The task involved integrating mechanical ductwork and plumbing in a restricted ceiling space above the residential floor without compromising the height from floor to ceiling despite the constant changes made to the design of the project on a tight schedule.
Project Summary
- Mechanical BIM modeling, shop drawings, and coordination across 511,779 sq ft of residential construction
- Mechanical ducts and plumbing coordinated within narrow ceiling spaces above residential units
- Floor-to-ceiling height preserved despite tight mechanical routing constraints
- Rapid RFI responses and field communication supporting continuous architectural and structural changes
- LOD 400 modeling delivered in Revit Fabrication 2021 for accurate, fabrication-ready mechanical documentation

Coordinating Mechanical Ductwork Within Tight Ceiling Space
Fitting mechanical ducts and plumbing above residential units without eating into floor-to-ceiling height is one of the toughest constraints in multi-residential construction. Our MEPF services team addressed this through:
- Mechanical and plumbing (MP) systems coordinated within narrow ceiling spaces above residential units
- Routing decisions made to protect intended floor-to-ceiling height throughout the building
- Regular coordination meetings with the design team and trades to resolve tight-clearance conflicts quickly
- Ceiling cavity constraints managed unit by unit across the full residential footprint
Quick Rerouting and Accurate Model Turnaround
Timely resolution of ceiling space conflicts depended on fast decision-making paired with disciplined model accuracy. This work included:
- Quick decisions on ductwork and plumbing rerouting to resolve ceiling space conflicts
- Accurate incorporation of trade submissions to keep the mechanical model current
- Time management and model accuracy emphasized to support smooth project execution
- Model revisions turned around quickly enough to keep pace with the project’s construction schedule
Managing Continuous Architectural and Structural Changes
Frequent architectural and structural changes within a time-bound schedule required disciplined BIM coordination backed by rigorous clash detection against every revision. Key outcomes included:
- Rapid responses to RFIs to keep mechanical coordination aligned with the latest design
- Timely communication with field teams to support effective, on-site coordination
- Delivery schedules maintained and design changes updated without disrupting project momentum
Dedicated Team Support for Fabrication-Ready Shop Drawings
Delivering accurate shop drawings through repeated design changes depended on a dedicated team focused on this project. Our team:
- Maintained a dedicated team for deliverables and coordination to manage project updates efficiently
- Delivered LOD 400 mechanical modeling and shop drawings in Revit Fabrication 2021
- Kept the mechanical scope on schedule across a 511,779 sq ft residential development
- Supported field teams with clear, up-to-date documentation throughout construction
The Modern project reflects how BIM Services applies precise mechanical coordination, rapid RFI turnaround, and dedicated team support to deliver clean, fabrication-ready mechanical systems across large multi-residential developments.
