Paul Industries builds controlled environments across Kansas, including facilities for veterinary biologics. This is the one sector where the regulator most engineers have never dealt with is the one that matters: veterinary vaccines and related products are licensed by the US Department of Agriculture through APHIS under the Virus-Serum-Toxin Act, not by FDA. Different statute, different agency, different licensing model, and a design team that arrives with a pharmaceutical playbook will be answering to expectations it has not read.

A licensed establishment, not just a licensed product
The structural difference worth understanding before designing anything is that in veterinary biologics the establishment itself is licensed, alongside the products made in it. That is not how most engineers think about a manufacturing facility, and it changes the status of the building.
The consequence is that the facility is part of the regulatory position rather than a container for it. What is installed, where products are made, how areas are separated and what the building physically does are matters the licensing agency has an interest in, which means facility changes carry a regulatory dimension that a purely mechanical change in a food plant would not.
For a design team the practical implication is about sequence rather than standards. Changes that affect the licensed establishment need to be handled through the client’s regulatory process before they are built, in the same way a change on a process safety covered installation goes through management of change first. A contractor who treats a facility modification as purely a construction matter, to be documented afterwards, creates a problem for the client that is considerably more awkward than a construction delay.
The second difference is what is being made. Veterinary biologics include live and inactivated organisms grown deliberately and then either inactivated or kept viable as the product. That puts the facility in the same engineering territory as any live-organism operation: containment of what is grown, separation between products, and a defensible position on how equipment used for one organism is made fit for the next.
The engineering that follows is therefore closer to a biologics facility than to a food plant, with the important addition that multi-product operation is common. A site making several products for different species, some live and some inactivated, has to demonstrate separation between them, and separation is a building characteristic before it is a procedural one.
What the facility has to demonstrate
| Requirement | Why | Built as |
|---|---|---|
| Containment of live organisms | What is grown must not leave uncontrolled | Pressure regime, dedicated exhaust, contained drainage |
| Separation between products | Cross-contamination between biologics | Physical separation, routes, dedicated equipment |
| Protection of the product | Contamination of the culture | Classified or controlled environment as required |
| Inactivation before discharge | Live material must not reach the drain | Effluent treatment with validated inactivation |
| Change control on the building | The establishment is licensed | Regulatory process before construction |
| Evidence of all of the above | Inspection of the establishment | Records generated by the systems themselves |
| Continuous load | Per year | Over ten years |
|---|---|---|
| 25 kW | $16,929 | $169,290 |
| 50 kW | $33,857 | $338,570 |
| 100 kW | $67,715 | $677,150 |
Kansas sits marginally below the national average tariff, and containment exhaust cannot be recirculated, so the energy profile of this kind of facility resembles a containment building rather than a conventional cleanroom. That is a real ongoing cost and it is moderate here compared with the high-tariff states.
Multi-product separation, which is the usual Kansas problem
The animal health corridor runs a lot of multi-product facilities, and that is where the difficult design conversations happen.
The question a facility has to answer is how it demonstrates that a product made in a shared building is not contaminated by another product made in the same building, and the honest answers are structural. Dedicated suites for products that warrant them. Campaign working with a defined and demonstrable changeover between campaigns. Dedicated equipment where shared equipment cannot be made defensible. Personnel and material routes that do not allow a shortcut between areas working on different organisms. And an air handling arrangement where areas do not share return air in ways that connect them.
What does not work is relying on procedure to compensate for a building that connects things which should be separate. Procedures degrade under production pressure and a shared return air path does not care what the procedure says. Where we are asked to improve an existing multi-product site, the productive work is almost always physical: separating air systems, creating proper transitions at boundaries, and establishing dedicated equipment where the argument for sharing was never strong.

Frequently asked questions
Do you build veterinary biologics and controlled environment facilities in Kansas?
Yes, across the animal health corridor and statewide: containment and classified suites, pressure regimes, dedicated exhaust, contained drainage, process utilities and the qualification package. On licensed establishments we work to the client’s regulatory process rather than treating a facility change as purely construction.
Who regulates veterinary biologics?
The US Department of Agriculture through APHIS, under the Virus-Serum-Toxin Act, rather than FDA. It is a different statute and a different agency from human pharmaceutical manufacture, and a design team arriving with a 21 CFR 210 and 211 playbook is working to expectations that do not apply here.
What does it mean that the establishment is licensed?
That the facility is part of the regulatory position rather than a container for it. What is installed, where products are made and how areas are separated are matters the agency has an interest in, so facility changes carry a regulatory dimension and belong in the client’s regulatory process before construction rather than being documented afterwards.
Is this like building a human pharmaceutical facility?
The engineering is closer to a biologics facility than to a food plant, with containment of live organisms, separation between products and validated inactivation of effluent. What differs is the regulatory framework and the licensing model, and the fact that multi-product operation is more common here than in most human pharmaceutical sites.
How is multi-product separation demonstrated?
Structurally, first. Dedicated suites where products warrant them, campaign working with a demonstrable changeover, dedicated equipment where sharing cannot be defended, personnel and material routes with no shortcut between areas, and air systems that do not connect areas through shared return. Procedure supports those; it cannot substitute for them.
Why does shared return air matter?
Because it physically connects two areas that the rest of the design is trying to keep separate, and unlike a procedure it operates continuously and without judgement. Where we are asked to improve an existing multi-product site, separating air systems is usually the highest-value physical change available.
What happens to effluent from a live-organism area?
It is collected in contained drainage and inactivated before discharge, with the inactivation validated in the same way any lethality process is: a defined target, monitored parameters and a batch record with a release decision. The drainage upstream of that treatment is part of the containment boundary and is built and documented accordingly.
Can an existing facility be extended?
Usually, and the sequence matters more than the construction. The change goes through the client’s regulatory process first, the design has to show how separation and containment are maintained during and after the work, and the construction has to be staged so that licensed production continues without its position being compromised.
Does Kansas energy cost affect the design?
Modestly. At 7.73 cents per kilowatt-hour against a national average of 8.13 (EIA, 2024), Kansas is marginally below the midpoint. It matters more here than in a conventional cleanroom because containment exhaust cannot be recirculated, so the facility carries a permanently higher air handling load, but the tariff makes that comparatively affordable.
How do I get a quote for a Kansas project?
Use the form on this page or call 201-450-8280. Useful inputs are what products the facility makes and whether any are live, how many products share the building, what containment level applies, whether the establishment is already licensed, approximate area, and whether this is new build or a change to an operating facility.
What is an Outline of Production and how does it affect the facility?
An Outline of Production is the document filed with USDA's Center for Veterinary Biologics describing how each product is made, including the facilities and equipment used. Changes to rooms, equipment or flow can require an amendment, so the facility design and its change control are tied to the licensing record from the start.
What containment level do veterinary biologics facilities usually need?
It depends on the organism: many production areas operate at biosafety level 2, with level 3 for certain pathogens and for work on select agents. The level sets the pressure regime, exhaust treatment, effluent handling and entry arrangements, and it is determined by the organism risk assessment rather than by the product type.
How are live and inactivated product areas separated in a veterinary biologics plant?
By separate rooms with independent air handling and pressure cascades, dedicated equipment or validated decontamination between uses, and material and personnel routes that do not cross from live to inactivated without a decontamination step. The separation is documented in the Outline of Production.
Do veterinary biologics rooms need ISO classification?
Aseptic operations such as filling and some formulation steps need classified environments comparable to human pharmaceutical practice, while fermentation and harvest areas are usually controlled but not classified. The classification follows the operation, and the licensing expectation is that the plant can justify its choices.
How is HVAC designed for a facility with both containment and cleanliness needs?
With separate air handling for containment zones, exhaust through HEPA filtration where the organism requires it, and pressure cascades that resolve the conflict between keeping product clean and keeping organisms in. Isolators and biosafety cabinets often carry the product-protection role inside a negative room.
How is drainage from a live-organism suite kept separate from the rest of the facility?
Through a dedicated drain system that collects to a kill tank or decontamination system before release, with no connection to general drains, and with the pipework sealed and accessible for inspection. Shared drains are one of the commonest containment breaches found in older facilities.
How does personnel gowning differ from a human pharmaceutical plant?
Gowning protects the operator from the organism as well as the product from the operator, so it may include respiratory protection and showering out on exit from higher-containment areas. The gowning sequence is set by the biosafety requirement first and the product requirement second.
How are autoclaves used in a veterinary biologics facility?
Pass-through autoclaves decontaminate waste and equipment leaving live areas and sterilise materials entering clean areas, and their position in the wall is part of the barrier. Cycle validation includes biological indicators for the organisms handled.
What about facilities for animal studies and challenge trials?
Animal rooms used for potency testing or challenge studies house infected animals and are containment facilities with their own air, effluent, carcass handling and entry arrangements. They are designed with the production facility but operated as a separate zone.
How is a facility inspected by USDA before licensing?
The Center for Veterinary Biologics inspects the establishment against its outlines, blueprints and standard operating procedures, verifying that the facility as built matches what was filed and that the controls are in place. As-built accuracy is essential.
Can a veterinary biologics facility also make human biologics?
The regulatory frameworks differ and dual use complicates licensing on both sides, so it is unusual. Where it is done, the facility is designed to the stricter of the two requirements in each area and the segregation is demonstrated to both agencies.
How is exhaust from a containment area treated?
Through HEPA filtration in housings that allow filter testing and safe change, with redundancy where the organism requires it, and with the exhaust discharged where re-entrainment into intakes is not possible. Exhaust filter housings are a maintenance and validation item, not just a duct fitting.
How long does a veterinary biologics facility take to license?
The licensing process runs alongside construction and product development, and the facility part depends on filing complete blueprints and outlines early. Facilities that file late or change after filing add months. Design with the filing in mind shortens it.
Do you work on the animal health corridor's pharmaceutical facilities as well?
Yes. Veterinary pharmaceuticals, as opposed to biologics, are regulated by FDA's Center for Veterinary Medicine under cGMP, which is closer to human pharmaceutical practice. Kansas has both kinds of plant, and the regulator determines the design brief.
What is the commonest design error in a Kansas veterinary biologics project?
Treating it as a human pharmaceutical facility with a different label. The containment requirements, the establishment licence and the effluent obligations are different, and a design that discovers them late is redesigned expensively.
