Healthcare professionals continue to contract with Tweet/Garot because of our thorough understanding of the intricacies of hospital construction and hospital mechanical systems.

Being the “Official Mechanical Contractor of Lambeau Field” is an honor and a source of pride at Tweet/Garot. Our relationship with the Green Bay Packers began in 1985 and continues to the present day. We installed the original HVAC systems for all luxury suites; new mechanical systems for the 2002 Redevelopment (which included boiler and chiller plants); 43 miles of ¾” tubing underneath the playing surface to heat the grassroots at 55 degrees year-round; radiant heating systems for both the main field and Ray Nitschke practice fields; the South End Zone expansion (which included more than 30 miles of snowmelt systems); and the 2016-17 upgrade to all private boxes.

In addition to our work with the Packers, Tweet/Garot has also installed a radiant field heating system at Target Field for the Minnesota Twins, was involved in the University of Notre Dame’s recent Campus Crossroads Project to upgrade the iconic Notre Dame Stadium, and has worked on various other stadium and arena projects throughout Wisconsin. We consider ourselves a national leader in sports stadium and arena mechanical design and construction.

We also have significant experience working with our tribal partners on casino HVAC and plumbing systems. We understand the importance of the customer experience that is associated with our tribal partners’ resorts and casinos, which has helped us better design and engineer their mechanical systems. From the humidity control measures that protect the integrity of the playing cards to the indoor air quality to the importance of integrated building automation systems, we ensure the highest level of customer satisfaction.
