When your project hinges on accurate capital and operating cost forecasts, you need a feasibility study that is technically rigorous, financially realistic, and clearly actionable. At MzansiWriters.co.za, we prepare engineering CAPEX/OPEX feasibility studies for manufacturing and processing projects that combine engineering precision with financial clarity to de‑risk investment decisions and secure stakeholder buy‑in.
What we deliver — Comprehensive, actionable feasibility studies
Every feasibility study we produce includes a complete suite of components designed to support decisions at boardroom and investor levels:
- Detailed equipment cost estimates (CAPEX) with vendor quotations, procurement margins, installation, and commissioning costs.
- Lifecycle operating cost models (OPEX) including labour, utilities, maintenance, consumables, and spare parts.
- Total cost of ownership (TCO) and lifecycle cost analysis (LCCA) across defined project horizons.
- Sensitivity and scenario analysis highlighting key cost drivers and break‑even thresholds.
- Risk register and mitigation measures for cost escalation, supply chain disruption, and regulatory changes.
- Executive summary and presentation‑ready slides for investor meetings and approvals.
- Technical appendices containing BOMs, P&ID excerpts, and assumptions log.
Why accurate CAPEX and OPEX studies matter
Poor costing undermines project credibility and kills returns. Our studies help you:
- Secure funding by presenting credible, third‑party‑validated numbers.
- Avoid costly change orders through realistic installation and commissioning estimates.
- Plan maintenance and spare parts provisioning to reduce unplanned downtime.
- Compare alternatives (e.g., new vs refurbished equipment, in‑house vs outsourced operations).
- Meet compliance and permitting cost expectations in your jurisdiction.
Our approach — engineering rigor + financial discipline
We combine proven engineering methodologies with financial modelling best practices to produce defensible estimates:
-
Scope definition and data capture
We align with your project scope, collect process flow diagrams, line lists, and historical data where available. -
Preliminary sizing and material take‑offs
Engineering sizing feeds the Bill of Materials (BOM) that drives vendor quotations and installation estimates. -
Vendor engagement & market benchmarking
We obtain current vendor quotations, benchmark against market indices, and apply locally relevant procurement multipliers. -
Bottom‑up cost build and escalation modeling
Component costs are rolled up into line items, then escalated by time/phasing, labour rates, and logistics. -
OPEX modelling and lifecycle analysis
We build year‑by‑year operating cost projections, including planned maintenance, consumables, and replacement cycles. -
Sensitivity, scenario testing, and risk quantification
Monte Carlo or deterministic sensitivity analysis identifies cost drivers and residual risk. -
Final report and presentation pack
Clear assumptions, transparent calculations, and executive recommendations to move to EPC, pilot, or full implementation.
CAPEX vs OPEX — quick comparison
| Category | What it covers | Typical drivers |
|---|---|---|
| CAPEX (Capital Expenditure) | Purchase, delivery, installation, civil works, instrumentation, commissioning | Equipment size, material specs, supply lead times, import duties |
| OPEX (Operating Expenditure) | Utilities, labour, maintenance, consumables, waste disposal | Throughput, labour productivity, energy prices, maintenance strategy |
Typical lifecycle cost breakdown
| Cost component | Example % of lifecycle spend (illustrative) |
|---|---|
| Equipment purchase & installation | 40% |
| Utilities and energy | 20% |
| Labour and supervision | 15% |
| Maintenance and spares | 12% |
| Consumables and waste handling | 8% |
| Regulatory, insurance, and overheads | 5% |
Note: We produce project‑specific LCCA tables tailored to your process, throughput, and location.
Who this service is for
- Investors and private equity assessing project viability.
- Plant engineers and operations managers planning expansions or retrofits.
- Project owners preparing for EPC tendering or bankable feasibility studies.
- Start‑ups and SMEs exploring process options and cost‑to‑produce scenarios.
Deliverables you can expect
- PDF feasibility report (40–120 pages depending on scope) with full findings and recommendations.

Timeline and engagement models
We adapt to your project scale and urgency:
- Rapid scoping study: 1–2 weeks — high‑level CAPEX/OPEX estimates and go/no‑go guidance.
- Standard feasibility study: 4–8 weeks — detailed bottom‑up costing, LCCA, and risk analysis.
- Bankable or investor‑grade study: 8–16 weeks — vendor validation, third‑party verification, and comprehensive appendices.
We offer fixed‑fee quotes for scoped work and milestone billing for larger engagements. Each engagement begins with a scoping call to confirm deliverables and timelines.

- We deliver clear, investor‑ready reports—not just raw spreadsheets—so non‑technical stakeholders can make fast decisions.
- We understand regional cost drivers and regulatory contexts, providing practical, localised advice you can implement.
- We maintain strict confidentiality and professional standards in every engagement.
Case example (anonymised)
A mid‑scale processing plant required a feasibility update for capacity expansion. We provided a bottom‑up CAPEX estimate, identified a 12% cost saving through alternative supply routes, and modelled OPEX under three process configurations. The final report was used to secure conditional funding and shaped the EPC tender scope.
Pricing overview (indicative)
| Study type | Typical price range (indicative) | Typical delivery |
|---|---|---|
| Rapid scoping study | ZAR 25,000 – 60,000 | 1–2 weeks |
| Standard feasibility study | ZAR 80,000 – 350,000 | 4–8 weeks |
| Bankable study | ZAR 350,000+ | 8–16 weeks |
Final pricing is provided after scoping and depends on data availability, site complexity, and required validation level.
FAQs
Q: How accurate are your estimates?
A: Accuracy depends on scope and data. Rapid scoping provides +/-30% range; standard studies aim for +/-10–15% with verified vendor quotes. We state uncertainty ranges and key assumptions in every report.
Q: Do you include environmental and regulatory costs?
A: Yes. We capture permitting, emissions management, waste handling, and compliance‑related costs as part of OPEX and CAPEX where applicable.
Q: Can you support tendering and vendor negotiations?
A: We can prepare EPC tender packages, evaluate contractor bids, and assist in technical negotiation to protect your cost baseline.
