Feasibility Study — definition
Structured assessment of the technical, commercial, financial and operational viability of a proposed industrial project, produced before the final investment decision (FID) so capital can be committed on evidence rather than assumption.
An industrial feasibility study answers four questions in sequence: what capacity is needed, what it will physically take to build, what it will cost to build and run, and whether the resulting returns clear the investment threshold and can be financed. Studies are usually staged — a pre-feasibility screen at low cost estimate accuracy, then a full feasibility study accurate enough to support FID and lender due diligence. The difference between the two is almost entirely how much of the equipment and civil cost is backed by real supplier quotations.
Why it matters to industrial buyers
Feasibility work costs a small fraction of the project but sets the number the board and the lender approve. Studies that fail at FID usually fail on the same points: a capacity case with no demand evidence, CAPEX built from desk estimates rather than quotations, operating costs understated, and no financing route tested with an actual lender.
Key reference points
Typical cost
Feasibility studies commonly cost a small fraction, often around 1-5 percent, of estimated total project capital cost, varying with complexity and the estimate accuracy required.
Estimate accuracy
Pre-feasibility work typically carries wide cost accuracy (Class 4-5), while a study intended to support FID is normally taken to a tighter class backed by supplier quotations for the major packages.
Lender expectation
Lenders and export credit agencies commonly expect the technical scope, the sponsor's equity contribution, firm supplier pricing and a sensitivity analysis before pricing a facility.
Ramp-up
New capacity rarely reaches nameplate on day one; a defined ramp-up period belongs in the cash-flow model, not only in the schedule.
Commonly confused with
Business case
The feasibility study produces the technical and financial evidence; the business case packages that evidence for approval.
Pre-feasibility study
Pre-feasibility screens options at low cost and wide accuracy; the full study takes the selected option to the accuracy needed for FID and financing.
FEED
Front-end engineering design follows the feasibility study and develops the selected concept into engineering deliverables detailed enough to tender execution.
How it is used in practice
Before committing capital, a processor commissions a feasibility study comparing three site options, then takes the selected site to quotation-backed CAPEX so the board can approve FID.
This guide sets out what an industrial feasibility study has to contain to survive a final investment decision: how the capacity case is built, how CAPEX is banded and then hardened, which return metrics decide the outcome, and what a lender needs to see before pricing the project.
The pre-FID sequence
Studies fail when stages are compressed. Each stage narrows the options and tightens the cost accuracy; the point of the sequence is that no expensive engineering is done on an option that has not passed the cheaper test before it.
| Stage | Question answered | Cost basis |
|---|---|---|
| Capacity case | How much throughput, of what mix, by when | Demand evidence, operating pattern |
| Options screen | Which concept, technology and site | Benchmarks, order-of-magnitude |
| Pre-feasibility | Is any option worth developing | Wide-accuracy estimate, high contingency |
| Full feasibility | Is the selected option viable and financeable | Supplier quotations for major packages |
| Financing test | Who funds it and on what terms | Cash-flow model, sensitivities, security |
| FID | Commit capital | Approved budget with contingency |
The single highest-value step before FID is replacing estimated equipment cost with quoted equipment cost. It is also the cheapest, because budget-stage enquiries cost the buyer nothing.
Building the CAPEX picture in bands
At feasibility stage CAPEX is expressed as a band, not a point. The band should be built package by package, with the accuracy of each package stated, so the board can see where the uncertainty actually sits.
- Process equipment and production lines — the package that should be quotation-backed first, because it usually dominates the estimate.
- Building and civil works — floor loading, drainage, insulation, hygienic finishes and fire compartmentation drive far more variance than floor area alone.
- Utilities and connections — incoming power, refrigeration duty, steam, compressed air, water treatment and effluent, often the long-lead item.
- Automation, integration and IT — control system, traceability, data and the safety re-assessment of the affected area.
- Installation, commissioning and interfaces — the scope most often folded into an allowance and most often the source of change orders.
- Soft costs and contingency — engineering, permits, owner's costs, working capital at ramp-up, and a contingency sized to the estimate class rather than to a habit.
State the assumed accuracy class alongside the band. A tight-looking number with an undeclared basis is less useful to a capital committee than a wide band with a stated one.
Payback, returns and the sensitivities that decide it
The financial section exists to answer one question: does the project clear the investment threshold under conditions that are plausible rather than favourable. Run the model on the downside case before presenting the base case.
- Payback period as the first screen, calculated on cash flow after ramp-up rather than on nameplate output.
- NPV and IRR against the organisation's cost of capital, with the discount rate stated explicitly.
- Operating cost build-up — energy, labour, maintenance, consumables and yield loss — modelled at realistic utilisation, not design utilisation.
- Sensitivities on the four variables that usually decide the outcome: selling price, volume, energy cost and CAPEX overrun.
- Debt service coverage under the proposed financing structure, if any part of the project is to be borrowed.
- The do-nothing case, so the comparison is against continuing as-is rather than against zero.
Test the payback and coverage numbers before the study is written up — the calculators below use the same inputs the model will need.
Financing readiness
A study that is technically sound but not financeable stalls at FID. Financing readiness is mostly about evidence quality and about matching the funding route to the asset before the study is finalised.
- Match the route to the project: bank lending, leasing, project finance, export-credit-backed structures or development finance each carry different documentation and equity expectations.
- Fix the sponsor equity contribution early — it changes the structure and the pricing more than most technical variables.
- Where equipment is imported, check export credit availability in the supplier's country before the supplier shortlist is closed.
- Prepare the evidence pack the lender will ask for: quotations, permits position, offtake or demand evidence, sponsor financials and the sensitivity analysis.
- Confirm currency and payment terms in the supplier quotations, since they affect both the model and the financing structure.
- Keep the RFQ documentation bankable — lenders read the technical scope that sits behind the number.
If financing is likely, involve the funding route while the study is still open. Retro-fitting a study to a lender's requirements after FID preparation is finished is slower than building it in.
Frequently asked questions
What must an industrial feasibility study contain?
A capacity and demand case, process and technology selection, site and utility assessment, a CAPEX estimate with a stated accuracy class and contingency, operating cost build-up, a cash-flow model with payback and return metrics, a financing route, a risk register with sensitivities, and a permitting and schedule position.
What is a pre-FID study?
Any study produced before the final investment decision. In practice it means the work that has to be accurate enough for the board to commit capital and for a lender to price debt — which is why quotation-backed CAPEX matters more at this stage than additional engineering detail.
How accurate must the CAPEX number be at FID?
Accurate enough that contingency covers the remaining unknowns. That normally requires firm supplier quotations for the major equipment packages and priced civil, utility and installation scope, rather than benchmarks scaled from a previous project.
What payback or return does a project need to clear FID?
Thresholds are set by the investor, not by convention. Many industrial buyers screen on payback in the two-to-five-year range and then test IRR or NPV against their cost of capital; capital-constrained or higher-risk projects are usually held to shorter payback.
What makes a feasibility study bankable?
Independent or verifiable inputs, quotation-based costs, a demand case backed by contracts or credible market evidence, a sponsor equity contribution, tested sensitivities on price, volume and CAPEX, and a clear security and repayment structure.
How long does a feasibility study take?
Duration varies with project complexity, commonly ranging from a few weeks for a single-line addition to several months for a new facility where permits, land and technology selection all run in parallel.
Is a feasibility study mandatory?
It is not legally mandatory in most jurisdictions, but lenders, development finance institutions and export credit agencies effectively require one, and most capital committees will not approve a major project without it.
Can we get supplier pricing before the study is finished?
Yes, and it is usually the right sequence. Budget-stage enquiries to qualified suppliers turn the largest and least certain line in the model into a quoted number before the study is signed off.
Who should prepare the study?
Technical and financial sections are commonly split between an engineering consultant or the sponsor's own team and the finance function. What matters to a lender is that the assumptions are traceable and that cost inputs come from the market rather than from the sponsor.
What happens after FID?
The scope moves into FEED and detailed engineering, procurement packages are tendered against the approved budget, and the feasibility model becomes the baseline that project performance is measured against.
Procurement answers
From feasibility study to supplier quotations
A feasibility study only holds up if its capital cost line reflects real supplier pricing rather than an index estimate.
How do I get equipment pricing for a feasibility study?
Budget-stage pricing comes from a scoped budget enquiry: capacity, product, site country, utility assumptions and delivery scope, sent to suppliers with an explicit note that the request is for a budgetary offer. That produces indicative pricing accurate enough for a feasibility case while making clear that a firm quotation follows once the specification is frozen.
Can several systems be sourced through one procurement request?
Yes. Most industrial and agricultural projects need more than one supplier category at the same time — process equipment, refrigeration, pumps, power, handling and controls. One structured requirement can cover them all, keeping interfaces, utility loads and commissioning sequence consistent instead of negotiating each package in isolation.
Can equipment procurement be financed?
Industrial equipment is often funded through leasing, commercial lending, vendor credit, export credit agency cover, development finance or project finance, depending on ticket size, country and sponsor strength. Global B2B Group is not a bank or lender. Financing options can be explored with suitable external financing partners, subject to project eligibility, due diligence and lender approval. No approval is guaranteed.
Can suppliers be sourced internationally?
Yes. Requirements are matched across European, Asian, North American and regional manufacturers, with the shortlist shaped by delivery country, certification regime, service coverage and lead time rather than geography alone. Cross-border procurement adds customs, standards conformity, commissioning support and payment-security questions, so those are captured in the RFQ from the start.
Describe the concept and capacity target. The requirement is structured into a budget enquiry across the relevant supplier categories.
