On-site clashes between HVAC systems and other disciplines lead to costly delays. Discover how digital design validation helps detect and resolve conflicts before installation—saving time, money, and reputations.
Ductwork through structural beams. Pipework clashing with cable trays. Valves that can't be accessed once walls go up.
These coordination issues aren't just frustrating—they're expensive. And in most cases, they could have been avoided if system logic had been validated earlier.
Coordination drawings aren’t enough. You need performance-aware clash detection.
That means checking not only where components are placed, but how the system is supposed to behave.
Physical space isn’t the only concern in HVAC coordination. In fact, some of the most costly clashes are functional, not geometric.
For example, control valves may be installed without sufficient clearance for servicing, and pipe crossings can also introduce pressure conflicts if flow directions aren't coordinated properly.
Similarly, missing hydraulic separation between primary and secondary circuits can go unnoticed in 3D but disrupt system balance entirely. There’s also the risk of overlapping responsibilities between the BMS and manual valves for zone control, leading to unpredictable behaviour.
And when pumps are forced to operate outside their efficient range due to layout constraints, the performance and lifecycle cost take a hit.
These don’t always show up in a 3D model—but they become painfully obvious during commissioning.
Fixing a clash in design takes minutes. Fixing it on site can take days—plus cost overruns, delays, and emergency procurement.
With digital validation, engineers can:
Hysopt’s platform enables performance-based clash detection by going beyond geometry to evaluate how the system will actually function.
It starts by importing spatial data from Revit or IFC, then overlays hydraulic logic, flow paths, and control behaviour directly onto the model. This makes it possible to highlight mismatches between physical routing and the intended operation.
From there, engineers can run full-system simulations to expose issues that wouldn’t show up in traditional clash detection.
This means you can resolve:

With simulation, these issues could have been identified during coordination—not three months after handover.
If you’re relying on 3D coordination alone, you’re missing critical HVAC performance conflicts.
Simulation and design validation help you build it right the first time—with fewer clashes, faster commissioning, and better outcomes.
