Why Engineering Teams Choose h2x
h2x was created by engineers for engineers. The founders had already dealt with the same calculation, sizing and design-change problems the product tackles today, and that experience still influences how h2x is developed and supported.
Design and Calculations Stay Connected
Design the system and run the calculations in the same project, reducing manual data transfer, double handling and the risk of errors between tools.
Accurate Engineering You Can Trust
See the calculations behind the design, adjust the criteria to suit the project and size systems using global industry methodologies.
Design Changes Don't Mean Starting Again
When the layout changes, update the design and check what it has affected. There's no need to rebuild a separate set of calculation files.
Outputs That Fit Existing Workflows
Create the branded drawings, sizing reports and Bills of Materials you need from h2x. If the project needs more coordination, take it into AutoCAD or Revit from there.

Real Engineering Results With h2x
Sparks+Partners Sized Pipework for a 60-Level Hotel in Just 2 Hours
Sparks+Partners used h2x to size the hot water pipework for a 60-level hotel in Sydney with a complex recirculation system. It took around two hours to complete the calculations, and the finished design could then be shared with a peer reviewer for checking.
