Owner Project Economics

Navigation: delivery-contracts | index

The GMP you produce doesn’t go into a vacuum. It goes into an owner’s appropriation request, which goes to a finance committee, which applies financial hurdles, which determines whether the project gets approved. Estimators who understand that process make better estimates — they know what questions the owner’s finance team will ask, where the number needs to land, and why some items become contentious.

This page is not about doing the owner’s financial analysis. It’s about understanding it well enough to work with it.

The Owner’s Capital Decision Framework

Owners authorize capital projects through a formal process. At most F&B and CPG companies:

Operations identifies a need (capacity, compliance, cost reduction)
        ↓
Concept developed → Class 5 ROM estimate
        ↓
Concept approval (Stage Gate 1) — "Is this worth pursuing?"
        ↓
Feasibility study → Class 4 estimate + preliminary business case
        ↓
Study approval (Stage Gate 2) — "Should we proceed to FEED?"
        ↓
FEED engineering → Class 3 estimate + full business case
        ↓
Full appropriation (Stage Gate 3 = AFE approval) — "Are we building this?"
        ↓
GMP signed → Construction → Startup
        ↓
Post-project review — "Did we get what we paid for?"

The AFE (Authorization for Expenditure) is the internal document that captures the full financial case for a capital project. It typically includes:

• Total project investment (GMP + OPC + working capital)
• Revenue and cost impact projections
• NPV, IRR, and payback calculations
• Risk summary
• Alternatives considered
• Approvals required (CFO for >$5M; Board for >$25–50M, depending on company)

Why this matters for the estimator: The Class 3 GMP estimate is the primary input to the AFE. If the GMP is higher than the owner’s model assumed, the AFE fails its financial hurdles. If the GMP is lower, the project may be rushed through without adequate engineering. The GMP sets the financial frame for the entire project.

Total Project Investment: More Than the GMP

The GMP is the construction contract value. The owner’s total project investment is larger. Understanding this prevents the common confusion where the owner’s budget seems to exceed the GMP.

Component	Description	Typical Range (% of TIC)
GMP (construction)	Cost of work + contractor fee + contingency	Base
Design / engineering fees	A/E, process engineer, specialty consultants	8–15% of TIC
Owner’s project management	Internal PM team, owner’s rep, project controls	2–5% of TIC
Permitting and regulatory	Permit fees, plan review, regulatory submissions	0.5–2% of TIC
Commissioning and startup	Third-party commissioning agent, vendor startup labor	1.5–5% of TIC (varies by sector)
First-fill materials	Chemicals, lubricants, spare parts	0.5–1.5% of equipment cost
Qualification / validation	IQ/OQ/PQ for pharma; food safety commissioning for F&B	2–4% of TIC (F&B); 5–8% (pharma)
Startup losses	Trial production waste, below-capacity ramp-up period	1–5 days of output value
IT / OT infrastructure	SCADA, MES, network, security	$50K–$500K
Owner’s contingency	Reserve above GMP contingency; management reserve	5–15% of GMP

See Owner Project Costs for the full OPC framework.

Working capital (inventory and receivables for the new production line) is usually tracked separately from project capital. For a new production line in F&B/CPG:

• Raw material inventory buffer: 2–4 weeks of production
• Packaging inventory buffer: 2–4 weeks
• Finished goods build before launch: 4–8 weeks
• Total working capital addition: can equal 15–30% of annual sales from the new line

This is not in the GMP and not in the owner’s project budget — it’s tracked in the P&L and balance sheet separately. But it is cash out the door.

Key Financial Metrics

Simple Payback Period

The most common first-pass metric. Easy to calculate, easy to communicate.

Simple Payback = Total Project Investment ÷ Annual Net Incremental Cash Flow

F&B/CPG typical standards:

• < 2 years: Approved without question in most companies
• 2–4 years: Approved with normal review; needs solid business case
• 4–6 years: Requires executive sponsorship; strategic justification needed

• 6 years: Difficult to approve unless strategic or compliance-driven

Worked example (from Worked Example Class 5 to Class 3):

Midwest Beverage Co. 20,000 SF expansion + 600 BPM filling line:

• Total project investment: $6.53M GMP + $750K OPC (commissioning, permitting, PM) = $7.28M
• New line capacity: 600 BPM × 60 min/hr × 75% OEE × 8 hr/shift × 250 days = 54M bottles/year
• Incremental contribution margin: $0.12/bottle (still beverage, competitive market) = $6.5M/year
• Less incremental operating costs (2 operators × $80K labor, utilities $120K, maintenance $80K) = $440K/year
• Net incremental annual cash flow: ~$6.1M/year
• Simple payback: $7.28M ÷ $6.1M = 1.2 years

This is a very attractive project. At this payback, financing and scheduling speed matter more than value-engineering another 5%.

Net Present Value (NPV)

NPV accounts for the time value of money — a dollar of cash flow 5 years from now is worth less than a dollar today.

NPV = Sum of (Cash Flow in Year t ÷ (1 + discount rate)^t) − Initial Investment

Year	Cash Flow	Discount Factor (10%)	Present Value
0	-$7,280,000	1.000	-$7,280,000
1	$6,100,000	0.909	$5,545,000
2	$6,100,000	0.826	$5,039,000
3	$6,100,000	0.751	$4,581,000
4	$6,100,000	0.683	$4,166,000
5	$6,100,000	0.621	$3,788,000
NPV			$15,839,000

Positive NPV means the project creates value at the company’s cost of capital. This project creates ~$15.8M of value at a 10% discount rate.

WACC (Weighted Average Cost of Capital): The discount rate the owner uses. For F&B/CPG companies: typically 7–10%. Higher for smaller companies or more leveraged balance sheets.

---

Internal Rate of Return (IRR)

The discount rate at which NPV = 0. A higher IRR is better.

IRR: the discount rate that makes NPV = 0 for a given cash flow profile

For the Midwest Beverage example above, IRR is well above 50% — this is a fast-payback project and IRR is extremely high. In practice:

F&B/CPG hurdle rates by project type:

Project Type	Typical Hurdle Rate (IRR)
Capacity expansion (strong demand signal)	15–25%
Cost reduction / automation	20–30% (faster payback expected)
Compliance / regulatory (mandatory)	Approved regardless of IRR; minimize cost
New product platform (strategic)	12–18%; strategic override possible
Greenfield new facility	15–20% (higher risk = higher hurdle)

Projects below the hurdle rate can still be approved if they’re strategic (entering a new market, maintaining a key customer relationship, complying with a regulation).

ROIC (Return on Invested Capital)

Measures ongoing efficiency of the capital deployed, not just project-level return.

ROIC = Net Operating Profit After Tax (NOPAT) ÷ Invested Capital

CPG companies track ROIC because investors compare it to the company’s WACC. ROIC > WACC = value creation. Most large CPG companies target ROIC of 15–25%.

A new production line that runs below capacity hurts ROIC in year 1 (capital is deployed; returns haven’t ramped). This is why owners are aggressive about startup speed and ramp-up efficiency — underperformance against the model creates ROIC drag.

Implication for estimators: Startup costs that delay first production (commissioning delays, USDA inspection waits, controls integration problems) have a real financial cost in the owner’s ROIC model. See Commissioning and Startup for the risks that cause delays.

The AFE Process — What Happens After You Submit the GMP

When the DB firm submits the GMP proposal, the owner’s project manager takes it to finance and prepares the AFE. The estimator is often not in the room — but the quality of the BOE determines how well the AFE reflects the real scope.

What finance will do with the GMP:

1. Stress test the cost. If there’s contingency in the GMP, they’ll ask: “What’s the base cost without contingency?” Some finance teams treat contingency as a slush fund rather than a risk reserve. Be prepared to explain the contingency basis.

2. Model cost overrun scenarios. Most AFEs include a sensitivity analysis: what happens to IRR if the project comes in 10% over? 20%? This is why the BOE exclusions list matters — a well-documented BOE limits the scope of potential overruns.

3. Challenge the business case assumptions. The finance team will push back on volume ramp-up assumptions, selling price assumptions, and operating cost assumptions. This is not your fight — but if cost assumptions in the business case seem unrealistic (e.g., operating cost far below your estimate of incremental utilities and labor), flag it.

4. Check the schedule. First production date drives revenue start. A 2-month construction delay = 2 months of lost revenue in the model. Finance will ask about schedule risk.

5. Confirm the OPC budget. If the owner’s PM has underestimated commissioning or startup costs, the total investment is underfunded even if the GMP is correct. This shows up as a budget shortfall during commissioning.

What Makes Projects Get Canceled After GMP

Understanding this helps you structure the GMP proposal to minimize risk of cancellation:

Cancellation Trigger	Root Cause	How Estimator Can Help
GMP comes in 20%+ over budget	Estimate was too low in earlier phases; owner anchored on the wrong number	Present Class 5 accuracy range honestly; don’t let owners treat ROM as a budget
Business case assumptions change	Volume forecast revised downward; market shifts	Not estimator’s domain — but don’t embed business case risk into the GMP
AFE financial hurdles not met	Project economics were marginal; GMP pushed it over	Surface VE alternatives during preconstruction that could move the needle
Scope creep during FEED	Owner added scope without updating the budget	Build scope change process into PCSA; issue Class 3 revisions for scope additions
Strategic priority shift	Acquisition, divestiture, market entry changes	Not estimator’s domain; but fast GMP delivery reduces exposure to this risk
Geopolitical / tariff shock	Sudden input cost change (steel tariffs, etc.)	Build escalation as a separate line item; make tariff exposure visible in BOE

How to Use This Page

When talking to an owner’s project manager: Speak in the language of payback and IRR, not just GMP dollars. “This VE option saves $180K on the structural scope with no impact on operations or compliance” is better than “we can save $180K on steel.” The owner’s PM will immediately calculate what that does to payback.

When setting contingency: The owner’s AFE models include contingency in the total investment. If you explain contingency as “the amount needed to reach P70 confidence on project delivery,” that’s a better conversation than “we added 10% because there might be surprises.” Finance understands probability language.

When explaining the BOE exclusions: “These items are excluded because they’re owner-side costs that belong in your OPC budget, not the construction contract” is a better framing than “we’re not responsible for that.” It shows you’re helping the owner build a complete budget, not just protecting your scope.
