Medical Marijuana Processing: New Construction


Medical Cannabis Cultivation and Extraction Facility (New Construction)

HEA was contracted to provide MEP consulting services for a large new facility initially dedicated to medical cannabis production with the capacity to handle future recreational demand. The facility utilized two-tier growing racks to maximize production capacity as well as a large ethanol extraction laboratory.

The MEP design showcased redundant HVAC systems with automatic changeover capabilities. In-rack, multi-level air distribution systems were developed in-house to provide adequate airflow at each canopy level. Hesnor Engineering Associates also designed all aspects of the building’s utilities (power, water, sewer, natural gas, etc.), and developed power distribution within the space for lighting and fire alarm, interior water distribution (including automated irrigation systems), natural gas distribution, and drainage, waste and venting systems. Provisions for emergency power with automatic changeover capabilities were incorporated into the design to protect the owner’s investment in the event of a power disruption event.

The power system design included utility coordination and provisions for a 200% future expansion in order to accommodate forecasted aggressive market demands. It also included an auxiliary generator to support security, IT and certain office functions in the event of a general power outage.
