Whether your company processes or distributes food, you want to ensure that your customers consume the safest product, processed in the most sanitary facilities.

At Gleeson, we specialize in clean room design concepts, incorporating the 11 AMI (American Meat Institute) design principles for food safety in each design:

- Distinct hygienic zones are established in the facility.
- Personnel and material flow are controlled to reduce hazards.
- Water accumulations are controlled inside the facility.
- Room temperature and humidity controlled.
- Room airflow and room air-quality control.
- Site elements facilitate sanitary conditions.
- Building envelope facilitates sanitary conditions.
- The interior spatial design promotes sanitation.
- Building components and construction facilitate sanitary conditions.
- Utility systems designed to prevent contamination.
- Sanitation integrated into facility design.

Food safety doesn’t start on the production floor - it starts in the design.

We’re proud to have our President, Ron Rens, featured in Food Engineering Magazine, sharing insight on one of the industry’s biggest challenges: preventing contamination risks before they impact operations.

From moisture management and airflow to eliminating harborage points and structural vulnerabilities, the reality is this - many food safety issues are rooted in facility design, not just sanitation practices.

At Gleeson, we design and build food processing facilities with food safety, operational efficiency, and long-term performance in mind, so problems are solved before they ever reach production.

Because in food plant construction, prevention isn’t just better, it’s critical.

50 years of showing up where it matters.

On job sites. In planning meetings. Inside facilities that need to work flawlessly from day one.

We’ve learned that building is only part of it.
Understanding how your operation runs is what makes the difference.
