Construction Management with Design Assist

Medisun Inc. is one of Canada’s top licensed cannabis producers. Located in southwestern Ontario, this state-of-the-art production facility enables Medisun to develop world-class cannabis growing systems that are sustainable and scalable, while having as little impact on the environment as possible.

Allyant was engaged by Medisun to provide construction management and design assist services for the first phase of the fit-out, which consisted of equipping a pre-engineered 43,000 sf building with specialized electrical, HVAC, plumbing, and interiors. A mechanical mezzanine structure was developed to house the air handling equipment and heat exchangers that serve the processing areas in the facility. Air distribution systems provide high air exchange rates via terminal HEPA filters for optimal cleanliness and contamination control. Electrical systems included state of the art high efficiency lighting, normal and standby power distribution and data / communications throughout.

The fit-out was constructed to comply with Good Production Practice (GPP) and Good Manufacturing Practice (GMP) for the trimming, drying, and packaging of cannabis for medical use. Finishes are high quality and durable and are readily cleanable such as epoxy coated floors, anti-fungal and moisture resistant drywall, walls and ceilings with epoxy coatings and stainless-steel furnishings and equipment.
