A safe path with snow-melt installation
A snow-melt installation on top of a 300-metre pedestrian bridge, suspended over a busy U.S. interstate highway and railroad tracks, became the first large-scale use of Uponor PP-RCT in North America. The bridge provides a safe pathway to thousands daily and combines the two sides of Utah’s largest public university in Orem.
On the recommendation of the project’s engineering company, the original specification calling for large diameter steel pipe for the hydronic-distribution piping was changed to PP-RCT. One motive was that the steel pipes would have been a lot heavier than PP-RCT, making the build more complicated, and the work would have involved welding. Another reason was that a non-corrosive plastic polymer would be better able to withstand the salt and magnesium chloride Utah uses for snow and ice melting. As PP-RCT is also far easier to handle, it is less labour-intensive to install.
The snow-melt portion of the job went smoothly, and installations were done without any problems, as PEX for snow melt was a known entity for the engineers.
