Planning a Feedlot for Future Expansion
Very few feedlots remain the same size or operate in exactly the same way forever.
Cattle numbers change. Feeding programmes evolve. New pens are added. Covered housing may be introduced. Roads, drainage, water systems and feed infrastructure that were adequate for the original operation can eventually become constraints.
That’s why future expansion needs to be considered before the first stage is built.
MLA’s Feedlot Design and Construction Manual makes a useful point when discussing future feed infrastructure: project requirements five years ahead, then allow additional room beyond that projection for future expansion. The principle is simple. Infrastructure designed only around today’s requirements can become difficult and expensive to expand later.
You don’t necessarily need to build everything now. You do need to know where it could go.
Start With Capacity: Where Could the Feedlot Be in 5 to 10 Years?
Before deciding where the next building or group of pens should sit, establish several capacity scenarios.
For example:
| Planning point | Current | Stage 1 | Future |
|---|---|---|---|
| Feedlot capacity | 5,000 head | 7,500 head | 10,000 head |
| Covered capacity | 0 | 2,500 head | 7,500 head |
| Number of pens | Current | Stage 1 | Ultimate |
| Feed demand | Current | Stage 1 | Ultimate |
| Water demand | Current | Stage 1 | Ultimate |
| Drainage capacity | Current | Required | Ultimate |
These numbers are illustrative, but the exercise is important.
Don’t simply ask “How many cattle do we need to accommodate next?”
Ask:
“If this operation eventually reaches its realistic maximum capacity, what will the site need to accommodate?”
That becomes the basis of the master plan.
What Should a Feedlot Master Plan Include?
A useful master plan doesn’t need every future building engineered in detail.
It should establish the likely position and relationship of the major infrastructure across the site.
That can include:
- Existing and future pens
- Existing and future covered housing
- Feed bunks and feed alleys
- Cattle lanes
- Receival and dispatch areas
- Hospital and recovery pens
- Feed preparation and commodity storage
- Roads and heavy vehicle access
- Water supply and reticulation
- Drainage
- Sedimentation systems
- Holding ponds
- Manure storage and handling areas
- Services and power
- Staff and operational facilities
- Future structural footprints
MLA’s Feedlot Design Manual breaks feedlot planning into 48 design and project-management areas, covering everything from site layout and water requirements through to pens, drainage, roads, feed systems, livestock handling and covered housing.
That gives an indication of why expansion needs to be considered as a whole-of-site exercise rather than simply finding somewhere to put another shed.
Some Infrastructure Is Much Harder to Expand Than Others
One of the most useful things a master plan can identify is what would be expensive or disruptive to change later.
Adding another section of fencing may be relatively straightforward.
Relocating a major road, drainage system, feed alley or structural column line because Stage 1 was built in the path of Stage 3 is very different.
Pay particular attention to:
Drainage and effluent systems
Can the system accommodate the ultimate developed area, or is there a practical way to expand it later?
Roads and feed alleys
Will future pens interrupt existing vehicle movements or create dead ends?
Water infrastructure
Can the main supply and reticulation system support the future cattle capacity?
Feed infrastructure
Can storage, processing and delivery systems support increased throughput?
Covered housing
Can additional bays or buildings be added without compromising ventilation, access or drainage?
Services
Are power, water and other services positioned so they can extend logically into later stages?
Spending more time on these interfaces during Stage 1 can avoid considerably more expensive changes later.
Drainage Capacity Needs to Follow the Master Plan
Drainage is one of the areas where expansion can have consequences beyond the new pens themselves.
Adding more feedlot area can increase the controlled drainage area and change the volume of runoff that needs to move through sedimentation and holding systems.
Adding covered housing changes the equation again.
Rainfall that previously landed on an open pen may instead become clean roof water, while uncovered sections of the expanded feedlot continue contributing to contaminated runoff.
That means future development should be considered when establishing:
- Drainage catchments
- Pen falls
- Main drains
- Sedimentation systems
- Holding ponds
- Clean-water diversion
- Roof-water collection and discharge
- Manure storage areas
Read our Feedlot Drainage & Effluent Management guide for more detail.
Pen Layout Can Lock In Future Development
Individual pen decisions eventually determine the overall footprint of the feedlot.
MLA notes that commercial feedlot pens can range from approximately 50 to 300 head, depending on operational requirements. Feed bunk allowance can also range from around 200 mm/head to more than 300 mm/head.
Those decisions affect much more than pen capacity.
Stocking density and bunk length influence pen dimensions, which then influence:
- Overall site footprint
- Feed road length
- Cattle lanes
- Drainage
- Water infrastructure
- Vehicle travel distances
- Future covered-housing dimensions
MLA also identifies pen slope as an important drainage consideration, with slopes generally ranging from 2.5% to 6% and approximately 3 to 3.5% identified as an effective range in its design guidance.
If future pens are likely, their location and levels should therefore be considered before earthworks for the first stage are finalised.
Covered Housing Needs Its Own Expansion Plan
If covered housing will be constructed in stages, the first structure needs to make sense as part of the eventual whole.
Before Stage 1 is engineered, consider:
- Which pens could ultimately be covered?
- Will future cover continue in the same direction?
- Where will future column lines sit?
- Will future buildings affect natural ventilation?
- Can machinery continue moving through the site?
- Where will additional roof water go?
- Will gutters and downpipes need additional capacity?
- Can cattle and feed movements continue during construction?
- Will future structures require different crane or construction access?
- Could Stage 1 physically prevent the preferred Stage 2 layout?
The answer doesn’t necessarily mean designing one enormous structure today.
It means making sure today’s structure doesn’t make tomorrow’s structure unnecessarily difficult.
MLA’s Covered Housing Systems Manual provides further guidance on the interaction between covered housing, feedlot layout and management. MLA notes that covered housing is an emerging option in Australia for protection from summer heat and wet winter conditions, while also acknowledging that system design and management need to be considered carefully.
Don’t Forget Construction Access
There is another practical question that can easily be missed on a staged project:
Can Stage 2 actually be constructed once Stage 1 is operational?
Future construction may require access for:
- Cranes
- Elevated work platforms
- Concrete trucks
- Structural steel deliveries
- Roofing deliveries
- Earthmoving equipment
- Civil contractors
A future building location may look perfectly logical on a site plan but become difficult to construct if operating pens, fences, feed roads or existing buildings block access.
Construction sequencing should therefore form part of the master plan.
Water Supply Needs to Match Future Capacity
Water availability and security can constrain feedlot growth. MLA identifies water security as a significant issue affecting the growth potential and size of feedlot operations.
When developing an expansion plan, don’t assess water requirements against current cattle numbers alone.
Consider:
Current demand → Stage 1 demand → ultimate development demand
Then assess whether the source, storage, pumps, mains and reticulation system can support those scenarios.
This can identify infrastructure that should be sized for ultimate capacity now and infrastructure that can economically be expanded later.
Feed Infrastructure Can Become a Bottleneck
Increasing pen capacity doesn’t automatically mean the rest of the feedlot can handle the additional cattle.
Feed preparation, commodity storage and feed delivery all need to scale with throughput.
MLA specifically recommends allowing room for future expansion and flexibility in feed preparation and commodity storage. Its guidance suggests projecting feedlot requirements five years ahead and then doubling that requirement for planning purposes, helping preserve space for future growth.
When planning expansion, ask:
- Can existing commodity storage support future throughput?
- Can the feed mill process the required volume?
- Can feed trucks service additional pens efficiently?
- Will additional feed roads be required?
- Where would future silos or storage facilities go?
- Will the expansion increase travel time per load?
The bottleneck in a 10,000-head operation may not be pen capacity. It could be the infrastructure supplying those pens.
Check Existing Approvals Before Planning the Expansion
Physical space isn’t the same as approved capacity.
Before developing an expansion concept, review:
- Existing development approvals
- Approved cattle capacity
- Environmental licence conditions
- Existing environmental assessments
- Approved site plans
- Drainage and effluent conditions
- Manure-management requirements
- Traffic conditions
- Existing staging or expansion conditions
Increasing capacity or changing the physical development may trigger additional planning or environmental approvals.
Our Feedlot Approvals guide explains the approval pathway in more detail.
Who Should Be Involved in the Master Plan?
You don’t necessarily need every consultant producing detailed designs from day one, but the disciplines affected by the future development should have input into the concept.
A feedlot expansion team may include a:
Feedlot planner to develop the overall operational layout and future capacity strategy.
Town planner to assess existing approvals and the implications of increased capacity.
Environmental consultant to assess environmental requirements, licences, receptors and future impacts.
Civil engineer to consider earthworks, roads, levels, drainage and future infrastructure capacity.
Surveyor to establish accurate levels, boundaries and existing infrastructure.
Geotechnical engineer where ground conditions influence future civil and structural works.
Nutritionist or feed specialist where expansion will affect feed preparation, storage or delivery systems.
TechSpan to develop the covered-housing component and determine how structural configuration, spans, columns, roof form, ventilation and construction sequencing can accommodate future stages.
Getting these people involved at concept stage doesn’t mean designing every future component immediately. It means avoiding decisions today that another discipline will need to undo tomorrow.
Feedlot Expansion Checklist
Before locking in the next stage, work through this checklist:
- What is our current approved cattle capacity?
- What is our realistic capacity in five years?
- What could the ultimate capacity of the site be?
- Where would future pens go?
- Which pens could eventually be covered?
- Can the drainage system accommodate future development?
- Can sedimentation and holding systems be expanded?
- Is the water source adequate for future cattle numbers?
- Can water storage and reticulation be expanded?
- Can feed preparation and storage support future throughput?
- Will feed delivery routes remain efficient?
- Are cattle lanes and handling facilities appropriately located?
- Are roads positioned for the final development rather than Stage 1?
- Are utilities capable of being extended?
- Is there sufficient construction access for future stages?
- Where will future roof water go?
- Do current approvals allow the proposed growth?
- What additional approvals could future stages trigger?
- Are we building anything now that would need to be removed later?
If the last answer is yes, it’s worth revisiting the master plan before construction begins.
What Should Be Built Now and What Can Wait?
Master planning doesn’t mean paying for the entire future feedlot today.
A useful exercise is to divide infrastructure into three categories:
Build now
Infrastructure required for the current development.
Allow for now
Infrastructure that isn’t required yet but would be difficult or expensive to accommodate later. This might mean allowing space, increasing capacity in a main service, positioning a road differently or engineering a structure with future stages in mind.
Build later
Infrastructure that can be added relatively independently when cattle numbers or business requirements justify the investment.
That distinction helps preserve future options without unnecessarily increasing today’s capital expenditure.
Where TechSpan Fits
For covered feedlot projects, TechSpan can work with the producer and broader project team to understand both the immediate building requirement and where the operation could go next.
During Concept, we look at the site, proposed capacity, operational requirements, future covered areas and how the building needs to interact with the wider feedlot.
During Construct, TechSpan carries the structural package through detailing, manufacture and construction.
During Configure, those requirements are developed into the structural solution, including building dimensions, spans, column positions, roof configuration, ventilation considerations and future stages.
That’s our 3C Advantage: Concept. Configure. Construct.
The objective isn’t to over-engineer Stage 1 for an expansion that may never happen. It’s to make deliberate decisions now so that, if the business does grow, today’s infrastructure doesn’t stand in the way.
Planning Your Next Feedlot Stage?
If you’re planning new covered housing or expanding an existing feedlot, bring the current site plan and the longer-term vision to the conversation.
Even if the next stage is several years away, understanding where it could go can influence the best location, orientation and configuration for the infrastructure you’re building today.
