Food Safety Things to Consider When Renovating a Facility

Construction, food safety

When food and beverage manufacturers aim to increase total throughput, they often face facility size constraints. Manufacturers can either expand their current facility or move operations to a larger building.

Due to property dimension limitations and the need for substantial additional square footage, procuring a new facility is the most common approach. Due to the difficulties associated with converting an industrial facility not previously used for food processing into a space suitable for food processing, it’s important to be considerate when selecting a new facility to minimize conversion time and costs.

Product Category and Risk

Before even looking at any specific facility, it’s important to consider the category of product you manufacture and what your specific production process requires of a facility, as well as what aspects of a facility might make manufacturing easier. For instance, rigid packaging necessitates substantial dry storage, while refrigerated finished goods benefit from pre-existing walk-in architecture. Conversely, confectionery or baking does not require extensive floor drainage or water supply.

The risk level associated with the product also plays a pivotal role. Facilities for dry mixes can be older or less pristine since contamination risks are minimal, controlled primarily by production equipment. However, ice cream production facilities demand extensive environmental risk mitigation, implying higher renovation costs if starting from a subpar condition.

Floor Plan

Arguably the most important consideration when looking at a facility is, to no one’s surprise, floor plan. It’s important that the shape, size, and orientation of rooms is suitable for how people, products, and materials need to flow through the building.

It’s sounds uselessly simple, but an excellent way to quickly gauge floor plan efficiency is to take a printout of the floor plan drawing, label each room for its potential purpose (i.e. production, offices, garb-up, warehouse, QA, etc) and draw arrows color coordinated to the movement of different types of employees and different types of materials.

If these arrows intersect too much, double back on themselves, or are just generally too long, try swapping room designations. If you can’t find a layout that works, the building probably isn’t a good fit.

Walls and Ceilings

As discussed previously, this consideration depends on your product category. But for certain products, the integrity of walls and ceilings is very important to mitigate environmental risk.. Certain walls and ceiling materials like dairy brick don’t require covering, if they are minimally porous and easily cleanable.

Also, other panel materials like PVC provide alternatives to FRP that may be more inexpensive, easier to mount, or both. It’s important to examine more than just surfaces, as the internals of walls and ceiling can sometimes harbor mold or other microorganisms. Mold mitigation is an expensive proposition.

Utilities

Utility service is arguably the most important consideration when looking at a building. While adding a new utility or increasing service isn’t typically an outrageously expensive endeavor, it can be time- and energy-intensive due to long lead times on utility equipment and the hassle of working with local officials.

It’s a similar story for utility access points. While relocating electrical hookups in a single room is inexpensive and straightforward, running a three-phase line across a quarter million square foot building is not. Oversized utility service is worth its weight in gold. It offers a ton of flexibility in scaling up operations at a given facility

Truck Traffic and Docks

We’ve already discussed how important it is for people and materials to be able to move through a facility for optimal production output. But, it’s equally important, perhaps moreso, that people and materials be able to move into and out of a facility quickly and easily.

Acquiring a facility with an inadequate number of docks or poorly positioned docks can quickly become a new production bottleneck, and unlike other bottlenecks, this one can be impossible to fix.

This is why it’s important not just to carefully consider the number and placement of docks, but also the traffic pattern for trucks to get there. How long does it take a truck to maneuver into the dock? Can incoming and outgoing trucks pass each other? Are there tight turns in the road leading up to the facility that could be difficult for trucks to navigate? If there are problems upstream that aren’t on the facilities property, they could become catastrophic to growth.

Plumbing and Drainage

Finally, for product categories that require floor drainage due to process or sanitation concerns, having adequate plumbing in place from the get-go is incredibly key, as adding it is often the largest line item in a renovation budget.

This is why renovating a space that hasn’t been previously used for food production of some fashion is so rarely done. Installing plumbing and re-doing floors can balloon into six or seven figures for really large facilities.

So, for all of the readers who came into this article expecting validation for your preliminary decision to convert your warehouse space into production space, hopefully I’ve given you some things to think about first.

Conclusion

All this being said, careful consideration of these factors can prevent a food or beverage manufacturer from buying themselves a shiny new bottleneck. Proper planning and evaluation are key to ensuring a smooth and cost-effective renovation process.

Strategies and Building Design Improvements to Help Prevent Birds

Bird droppings and nesting materials, if allowed to accumulate over time, can cause severe damage to building facades, ledges, loading docks, walkways, roofs and more. Building materials such as stone, wood and metal can be damaged due to the acidity of the bird droppings. And in extreme cases, a buildup of bird droppings can impact the structural integrity of a structure. Also, roof drains can become clogged, and fire hazards from packed nesting materials around electrical fixtures can develop. Not to mention all the possible diseases that can result from disturbing bird droppings! Rather than waiting until these bird problems develop and result in potentially expensive remediation, in most cases, it will be cheaper to consider bird prevention design elements beforehand—specifically, in the design-build stage (ideally) or the retrofit stage (alternatively).

Before we can review the building design elements, it is best to review the types of areas that birds prefer to land, roost and nest. This way, when considering a design element, considering the kinds of spaces they prefer to set up camp will make more sense.

  • 90-Degree Ledges
    • Building ledges
    • Decorative elements
    • Truck bay bumpers
  • Knee Walls (parapet ledges)
    • Typical construction around most commercial buildings
    • Roof structure types
    • Flat based surface areas
  • Covered Overhangs
    • Loading docks
    • Building canopies
    • Interior building structures
  • Roofing Equipment
    • Under HVAC units
    • Ductwork
    • Roof equipment
  • Water Sources
    • Retention ponds
    • Decorative fountains
    • Any water source (natural or otherwise)
  • Food Sources
    • Fruit trees
    • Trash removal
    • Container practices
    • Proximity to building
  • Light Fixtures and Electrical Items
    • These items provide warmth
    • These items provide elevated areas to survey area and avoid predators

In the design-build phase of the project, when we work with architects, we always recommend decreasing the number of 90-degree ledges or reducing the ledge depth surface area as much as possible. In those areas that we are not able to reduce or eliminate the ledge, we would recommend a landing-based deterrent product such as a bird spike, bird wire, ledge exclusion system or electrified shock-based bird control product. Each of these types of bird deterrent items has different pros and cons.

Bird Spikes

Bird spikes are a type of bird deterrent/and anti-roosting device that will make it hard for a bird to land on a leading ledge and close its wings as it walks onto the ledge surface. When a bird’s landing process is made more difficult, combined with a reduction of the surface landing area, the birds will be deterred from the leading ledge area. Most types of bird spikes have thin metal/plastic rods that are attached to a solid base that point in an upward direction. Bird spikes come in various widths depending upon the surface ledge width area. Bird spikes can be mounted to just about any ledge/surface. Bird spikes can be installed on numerous types of building ledge types and sizes. Bird spikes can be an effective deterrent on gutters, signs, rooflines, cameras, pipes, parapet/knee walls, and related building surfaces.

A con of using bird spikes is that bird spikes are primarily designed to deter larger birds like pigeons. Smaller birds such as sparrows or starlings will not be deterred with bird spikes. A smaller bird can move within and around the rods to use the rods to hold nesting materials within the strands of rods to hold their nesting materials within the bird spike to create a nest. Another con is that larger quantities of bird spikes are unappealing to the building aesthetics.

Bird wire

A bird wire system is a combination of stainless-steel posts that are either epoxied or tapped and drilled into the surface area (typically mortar lines/joints). After the stainless-steel post is mounted, a thin monofilament stainless steel wire is secured between the posts with a micro-spring. The wire is tensioned between the two posts. As pigeons or larger birds attempt to land on treated areas, they will not be able to close their wings and thus will be deterred from landing on treated areas.

A con of using bird wire is that it is typically only effective against larger birds.

Ledge exclusion

Ledge Exclusion

The goal is to turn a 90-degree angle into a 45-degree angle. When you have a ledge that has a base landing area and a return wall area, this allows birds a great shelter area and an ability to survey surroundings. By creating a 45-degree angle, you take a bird’s ability to land and get a foothold and land on the surface. The product is effective for larger birds such as pigeons and smaller birds, too.

The only real con of the changing the ledge structure is matching the building finish. However, this is the best bird exclusion method that is effective against all bird species.

Shock Track

Shock track is a low-profile shock track system with a minimalist low profile, and virtually invisible solution to deter and prevent birds from landing, roosting or nesting on building ledge-based surfaces. The shock track system will deliver a mild/startling electric shock when the bird contacts the strip. Shock track systems are a great option when building/structural aesthetics are a key factor for the facility.

For larger areas such as loading docks, canopies, and related covered structures, netting is the main bird exclusion method.

A few cons for a shock system are that at times, you may have some arcing with heavy snow or water collection when connection area of the strips make contact, and this system is typically only effective against larger birds.

Bird netting

Bird Netting

Bird netting is an exclusion method of bird control. It is intended to be installed on buildings, loading docks, warehouses, airport hangers, transportation facilities, barns, food silos, over building exteriors, balconies, parking garages, rooftops, HVAC units, bridges, agricultural crop applications, ponds, and any other surface that netting hardware can be installed. Bird netting is the best method for excluding all pest bird types. Specifically, seagulls, pigeons, sparrows, starlings, and crows can all be excluded from bird netting.

Bird exclusion netting will prevent birds from gaining entry above any areas that are netted off. It excludes pest birds from roosting and nesting. There are various types of netting and mesh sizes. When selecting the type of netting and mesh size, it is critical to both the target pest bird and where the netting is being installed.

By far, bird netting the best bird exclusion method to control all bird species. The only con of bird netting is that depending upon the application, and the cost can be expensive.

In conclusion, when considering the design-build phase or a retrofit project, the aforesaid areas that are attractive to birds to land, roost and nest should be considered. In most cases, birds can be prevented with a bit of planning.

Remember to also consider surrounding areas (proximity of birds), acceptable pest bird threshold levels, reducing all food and water sources, and closing off all possible entry points. The goal is to not only prevent the birds from setting up shop on the building, but we want to try to keep them an acceptable distance away, too.
