We’re proud of our team for showing up, riding together, and supporting a cause that touches so many families. Events like this remind us what a community can do when people come together with a shared purpose.

Thank you to everyone who rode, donated, volunteered, or cheered from the sidelines. We were glad to be part of a day dedicated to moving toward a world without cancer.

Plumbing is more than what you see after the walls go up. It’s what makes a facility function.

At icon Mechanical, our plumbing capabilities bring together early coordination, constructability-focused planning, prefabrication, and experienced field ex*****on to deliver reliable systems for complex facilities.

From domestic water and sanitary systems to storm drainage, specialty piping, equipment connections, and plumbing prefabrication, we focus on getting the details right before and during installation.

Because better coordination means fewer conflicts, less rework, and plumbing systems built to perform for the long term.

Plan it. Coordinate it. Build it. Make it perform.

251 prefabricated bathroom pods. 224 custom headwalls with integrated medical gas and electric. One bustling St. Louis hospital.

Our work at BJC proved to be our most expansive pod and headwall program to date, and included coordinating workflows, manpower, and logistics in some of the most constrained site conditions imaginable. A major thoroughfare on one side, the hospital's main entrance on the other, with zero staging area available.

Here's how we did it. Check out the full case study: https://iconmech.com/projects/bjc-healthcare-campus-renewal-patient-room-pods-and-headwalls
