What we design

  • Four-season MEP systems — O'Fallon's continental climate demands heating and cooling systems designed for extreme temperature ranges
  • Freeze protection design for piping, HVAC equipment, and domestic water systems in sub-zero winter conditions
  • High-efficiency heating plant design with attention to natural gas utility infrastructure and backup heating capacity
  • Humidity management for winter-dry conditions — building envelope and mechanical systems must address low RH in heating season
  • Snow and ice load coordination between MEP rooftop equipment and structural engineering for heavy snow regions
