SPECIALTIES FEATURED WITH THIS PROJECT:

Mechanical

  • Lakeleaf Cultivation in Onamia, Minn., entrusted Egan Company’s Mechanical team to deliver critical mechanical systems for its new state-of-the-art cannabis Growco facility.
  • This specialized facility includes 12 individual grow rooms, an extraction room, lab space, and offices—all housed within a precast stand-up building designed for operational efficiency and sustainability.
  • The Mechanical team installed fertigation piping, gas piping, customer supplied RTU’s and condensate piping throughout the facility.
  • Fabric ductwork was installed to optimize airflow in the grow rooms and other areas.
  • The team completed all plumbing systems tailored to the unique needs of the cannabis cultivation operation.
  • A notable highlight was the rapid placement of 48 rooftop HVAC units set in just two days.
  • A key to project success was the extensive use of prefabrication: all plumbing and piping components were fabricated offsite in Egan’s controlled shop, ensuring quality, precision, and a faster, safer installation on-site.
