School Building
HVAC BIM Coordination for School Building, Austin, TX
Delivered fully coordinated HVAC and hydronic systems, resolving all clashes pre-construction to ensure seamless installation and on-time project delivery.
Overview
Project Overview
When an MEPF firm needed reliable BIM expertise for a 65,000 sq. ft. educational campus in Austin, TX, they turned to us. With 25 mixed-story units ranging from 800 to 1,500 sq. ft., the project demanded high-precision LOD 400 coordination across HVAC and Mechanical Piping systems.
We ensured every system was precisely coordinated, each clash was resolved, and the models were delivered on schedule.

Client Challenges
Pain Points of the Client
Unresolved clashes, inadequate documentation, and a strict submission deadline threatened on-time delivery across 25 school units.
01
Unresolved Cross-disciplinary Clashes
Continuous conflicts between architectural, structural, and MEP systems were stalling coordination and threatening the construction schedule.
02
Strict Submission Deadline
Tight project timelines combined with inefficient cross-team communication made meeting delivery milestones increasingly difficult.
03
Mechanical Equipment Clearance Gap
Insufficient clearance planning around mechanical equipment created risks for accurate installation and future system accessibility.
04
Inadequate MEP Documentation
Poorly structured MEP documentation was making it difficult to support effective long-term facility operation and maintenance.
05
Lack of System Visibility
Limited cross-discipline insight led to late-stage discoveries, causing costly adjustments that proactive coordination could have prevented.
06
Needed Fully Coordinated LOD 400 Model
Project demanded a clash-free LOD 400 model with accurate documentation, ready for direct construction execution on time.
07
Truss Coordination Constraints
Routing HVAC systems without interfering with structural truss zones required precise spatial planning and iterative clash reviews at every routing decision point.
08
Tight Timeline Pressure
Delivering coordinated outputs within strict submission deadlines while maintaining full LOD 400 accuracy across all 25 units.
Our Approach
How We Solved It
A structured BIM coordination workflow using Revit for LOD 400 modeling and Navisworks for clash detection kept HVAC and piping systems aligned.
Mechanical System Modeling
Modeled mechanical piping systems with equipment clearance and maintenance access requirements built in.
Clash Detection & Coordination
Ran proactive clash detection cycles and resolved conflicts across architectural, structural, and MEP systems.
Construction Documentation Support
Supported construction-ready documentation derived from the coordinated LOD 400 model.
Coordination Meeting Support
Maintained structured issue tracking and cross-team alignment through coordination reviews.
Execution Strategy
Proactive HVAC Coordination Across 25 School Units
Our team followed a structured BIM coordination workflow using Revit for LOD 400 modeling and Navisworks for clash detection. We ensured proactive coordination, real-time updates, and precise modeling to ensure seamless integration of HVAC and piping systems.
