Turnkey & EPC — brownfield projects
Meat plant modernisation
Meat plant modernisation is refurbishment carried out on a working site: the building is occupied, the line is running, and the works have to fit around a production schedule that does not pause. INTERCOOL plans and delivers phased refurbishments of operating slaughterhouses and processing plants — production processes and buildings together — to current EU and USDA standards, without taking the site out of supply.
What is meat plant modernisation?
Meat plant modernisation — brownfield refurbishment of an existing meat plant — means bringing an operating slaughterhouse or processing plant up to current standards while it keeps supplying its market.
The scope is genuinely plant-wide. INTERCOOL's refurbishment projects have comprised all production processes as well as buildings: the entire slaughter process from reception through to packaging and dispatch, production of canned products, rendering, refrigeration and waste water treatment. Each has its own standard, utilities and hygienic constraints, and in a brownfield project all of them are re-planned inside a shell designed around the previous layout — up to today's welfare, hygiene and by-product regulations, without emptying the building.

Definition
- Meat plant modernisation
Meat plant modernisation is the phased refurbishment of an operating meat plant — its production processes and the buildings that house them — to bring the facility up to current welfare, food-hygiene, by-product and environmental standards without taking the site out of production.
Why modernising an operating plant is a different engineering problem
On a greenfield site the process design leads and the building follows. On a brownfield site the constraints lead: column grids, floor levels, drainage runs, roof loadings and utility capacities, plus a production plan that must be met while the works proceed. At a pig slaughterhouse in Spain, 2,630 m² of chilling area was engineered into a plant already in operation at 800 pigs/hour, achieving 0.8–0.9% chill loss on 86 kg carcasses at a 14-hour process.
The sequencing is the deliverable. In one of INTERCOOL's multi-site refurbishment programmes, seven plants were taken one at a time, with no decrease in total supply volume across the group. Phasing is where a modernisation project is won or lost, well before any equipment is specified.
How a phased modernisation is delivered
INTERCOOL applies a structured EPC contract methodology recast for a plant that cannot stop. A single point of responsibility across the sequence is what keeps the phasing plan intact once site work begins.
Condition survey and baseline
Establish what the plant actually is today rather than what its drawings say: real process capacities, hygienic zoning, refrigeration duty, by-product handling, waste water treatment, building fabric and utility headroom. Everything downstream is priced and sequenced off this baseline.
Modernisation study
Produce the decision basis the owner needs before committing: expected capital investment, necessary footprint, and the consequences for water and energy demand, environmental impact, manning, and internal and external logistics.
Phasing and shutdown plan
Break the scope into packages that fit genuine production windows — weekends, seasonal troughs, single-line stoppages — and define what the plant runs on while each package is out.
Detailed design and specification
Design the new processes and the building works that carry them, to EC 1099/2009, EC 852/2004, EC 1069/2009 and, where the plant supplies US-regulated markets, USDA standards. Equipment and processes are chosen against BREF (11.03), Best Available Techniques in the Slaughterhouses and Animal By-Product Industries.
Works and installation in windows
Execute each package inside its agreed window: on-site building activities, process and utility equipment installation, and the retrofit interface details that a brownfield job lives or dies on.
Cut-over, commissioning and training
Bring each package into production, commission it against the design intent, and train the operators who will run it. On a phased project this happens repeatedly rather than once, which is why the commissioning plan belongs in the phasing plan from the start.
Standards a modernisation brings an existing plant up to
| EC 1099/2009 | Protection of animals at the time of killing — governs the lairage, restraint, stunning and bleeding arrangements an older plant commonly has to change |
|---|---|
| EC 852/2004 | Hygiene of foodstuffs — layout, surfaces, product and personnel flows, and the cleanability of production areas |
| EC 1069/2009 | Collection and separation of animal by-products is facilitated according to the EU by-product regulation |
| USDA standards | Applied in addition where the plant supplies or exports to US-regulated markets |
| BREF (11.03) | Best Available Techniques in the Slaughterhouses and Animal By-Product Industries — the environmental benchmark against which equipment and processes are chosen |
Where brownfield projects actually go wrong: the interfaces
Defrost and refreeze cycling
Insulated structures housing a quick chiller are subjected to frequent defrosting and refreezing through routine cleaning. Construction guidelines have to hold long-term structural integrity under that cycling.
Vapour barrier integrity
Maintaining vapour barrier integrity where new insulated construction meets old fabric is one of the interface details a refrigeration retrofit is designed around.
Pipe penetrations
Every service crossing an insulated envelope is a thermal and hygienic breach unless it is detailed. In a retrofit those penetrations are detailed against an envelope that was not designed to receive them.
Insulated panel finishes
Panel finishes have to suit the cleaning regime and the product zone they enclose, and they have to terminate correctly against surfaces that were never designed to receive them.
Steel columns on insulated flooring
Installing steel column supports on insulated flooring is a structural and a thermal detail at once.
Integration with adjoining components
New construction has to be integrated with the adjoining building components that stay. That interface list is written during design, not discovered on site.

Owner-side, and not tied to a supplier
A modernisation puts the owner opposite several contractors at once, usually while running a plant. INTERCOOL sits on the owner's side of that table.
Review and supervision. Before installation, the selected refrigeration contractor's proposed equipment and systems are evaluated against what the process requires, and oversight continues through installation and commissioning.
Unbiased equipment selection. INTERCOOL is not tied to proprietary equipment and gives supplier-neutral recommendations. On a brownfield project, the right answer is frequently to keep and re-use an existing asset.
Frequently asked questions
Can a meat plant be modernised without stopping production?
In practice a plant is modernised in phases rather than in one shutdown. INTERCOOL plans the works for minimal disturbance of production on the individual sites, breaking the scope into packages that fit genuine production windows. On multi-site programmes the same principle applies across the group — plants are taken one at a time, so total supply volume is maintained while each site is worked on.
Does modernisation cover the buildings, or only the process equipment?
Both. In INTERCOOL's refurbishment projects the scope has comprised all production processes as well as buildings — the entire slaughter process from reception until packaging and dispatch, plus rendering, refrigeration and waste water treatment. Treating a modernisation as an equipment swap is a common way to under-scope it, because the building fabric, utilities and hygienic zoning usually have to change with the process.
Which standards does a modernisation bring an older plant up to?
The usual uplift targets are EC 1099/2009 on the protection of animals at the time of killing, EC 852/2004 on the hygiene of foodstuffs, and EC 1069/2009 on animal by-products, with USDA standards applied in addition where the plant supplies US-regulated markets. Equipment and processes are chosen according to BREF (11.03), Best Available Techniques in the Slaughterhouses and Animal By-Product Industries.
What technical risks does a brownfield refrigeration retrofit have to be designed around?
The interfaces between new insulated construction and the existing structure. In particular, an insulated structure housing a quick chiller has to withstand the frequent defrosting and refreezing that routine cleaning brings, so extensive construction guidelines are needed to hold its structural integrity long-term rather than only at handover.
What should a modernisation study tell an owner before they commit?
It should state the expected capital investment and the necessary footprint, and set out the consequences for water and energy demand, environmental impact, manning, and internal and external logistics. Those are the figures that decide whether a phase is worth doing, and they are what allows scope to be cut deliberately rather than abandoned mid-project.
Is INTERCOOL tied to particular equipment suppliers?
No. INTERCOOL is not tied to proprietary equipment and gives objective, supplier-neutral recommendations, working as an independent partner on the owner's side. That includes reviewing the documentation of the refrigeration contractor the owner selects, and supervising installation and commissioning with on-demand site visits and remote decision-making assistance.
