icon Mechanical is expanding its business in a new 40,800-square-foot headquarters in Granite City, Illinois, in the St. Louis market.  Contegra Construction Co. led a design/build team that completed the two-story headquarters, the latest addition to icon’s 10-building campus. 

In addition to hundreds of trade workers on projects, icon employs more than 150 people at its company campus.

Located at 1616 Cleveland Blvd. in Granite City, the headquarters is a showcase for highly efficient building systems.  Working with Contegra, icon used Revit 3-D Modeling to coordinate all building systems to deliver optimal energy efficiency.

The building is constructed of tilt-up concrete panels and features:

  • An atrium of polished concrete bathed in natural light from skylights and featuring an assembly room with “living room” seating for company gatherings and celebrations;
  • A perimeter of glass walled offices to allow more light to penetrate the building core;
  • LED lighting throughout and open interior workspace with clear sightlines to facilitate collaboration;
  • Exposed structural steel and ventilation systems in the ceiling as a nod to icon’s industrial clients and its prowess in HVAC systems.  Likewise, two stairways feature structural steel handrails.

The new headquarters was designed to blend in with icon’s campus which also features modular assembly; fabrication facilities for piping, high-purity systems, sheet metal, stainless steel, heavy metal and other specialty components, as well as a service and safety center; warehousing and additional office space.

At icon’s request the design/build team is made up of St. Louis area firms.  Joining icon and Contegra on the project are Juneau Associates, civil engineer; Gray Design Group, architecture and interior design; Alper Audi, structural engineer; and a host of highly proficient subcontractors.

Founded in 1995, icon Mechanical has grown into one of the nation’s most innovative design-build and prefabrication/modularization mechanical engineering firms. The company employs around 500 professional and craft workers and has offices in St Louis, Missouri and Nashville, Tennessee, in addition to its Granite City, Illinois headquarters.
