Building Investor-Grade Studies Without Gold-Plating

In capital project development, few tasks are more scrutinized—or more misunderstood—than preparing studies for investors. Everyone involved knows what’s at stake: studies must demonstrate the project’s potential, reduce uncertainty, and build confidence with those who will fund the next phase. But in the race to meet those expectations, teams often overcompensate.

They produce overly detailed studies, introduce expensive scope enhancements, and add layers of analysis that, while technically impressive, do little to improve execution certainty or decision-making. This phenomenon—known as “gold-plating”—can delay projects, inflate budgets, and mislead investors into thinking risks have been resolved when, in fact, they’ve only been disguised with polish.

Investor-grade studies aren’t about including everything. They’re about including what matters. The challenge is knowing where that line is—and having the discipline to stick to it.

Why Gold-Plating Happens

Gold-plating is rarely intentional. It usually begins with good intentions: project sponsors want to strengthen the investment case. Engineers want to show diligence. Consultants want to prove value. Leaders want to avoid scrutiny. And everyone wants to reduce the risk of rejection or delay at the next gate.

As a result, scope expands. Design gets refined well beyond what’s needed. Modeling is pushed to levels of precision that outpace the quality of the inputs. Optional features make their way into the base case, and what began as a targeted study becomes a fully engineered proposal—one that’s expensive, slow, and difficult to defend when the real-world project unfolds differently.

Gold-plated studies also tend to obscure key risks. They look authoritative, even when they haven’t been tested. That veneer can create a false sense of certainty among decision-makers—until execution begins and reality exposes what the study failed to anticipate.

What Investors Actually Want

Investors and capital committees don’t expect a flawless project. They expect a project that is well understood. That means clarity around assumptions, transparency around risks, and a realistic path to execution and return.

What matters most is that the study presents a plan grounded in real conditions. Timelines should be tied to achievable milestones. Cost models should reflect current market conditions, not legacy estimates. Scope should be defined clearly, with a visible link to how the asset will be built and operated—not just how it will look in a model.

Investor confidence comes from knowing the team understands the uncertainties and has a structure to manage them—not from added pages, extra diagrams, or overly refined design elements that won’t survive value engineering later.

How Gold-Plating Undermines Study Integrity

Beyond cost and time, gold-plated studies introduce a deeper issue: they erode the study’s credibility. Overdeveloped designs raise questions. Why was so much engineering done at this stage? Is this the actual plan, or just a vision? Can the project afford everything that’s included? What happens when it needs to be value-engineered back?

These questions slow down approval. They increase the number of review cycles. And they create confusion about what is fixed versus what is still open to adaptation. Instead of accelerating decision-making, gold-plated studies create uncertainty—exactly the opposite of what was intended.

They also lock in expectations. Once a certain level of detail is presented, it becomes hard to walk back. Changes are seen as regressions. Scope reductions feel like cuts, even when they’re necessary. Teams spend more time defending the gold plating than delivering the core of the project.

How to Deliver Quality Without Excess

Investor-grade doesn’t mean exhaustive. It means deliberate. The most respected studies are those that present clearly defined scope, transparent assumptions, reasonable cost confidence, and visible alignment with execution. They offer just enough design to demonstrate viability—but leave room for evolution. They map out key risks and explain how they’ll be handled—not just that they exist. They show a schedule that’s grounded in local realities—not idealized models.

What elevates these studies isn’t more detail—it’s stronger discipline. Every element included must serve a purpose. If it doesn’t help the investor understand deliverability, risk, or return—it doesn’t belong. This approach doesn’t just reduce time and cost. It increases trust.

Creating Investor Confidence Without Overengineering

Creating a credible investment study is about balance. Too little detail, and it appears rushed or underdeveloped. Too much, and it feels bloated and inflexible. The goal is to hit that middle ground: technically sound, commercially credible, and operationally realistic.

That means staying focused on what drives the investment decision. Will the asset be buildable under the proposed timeline? Are the cost inputs recent, and grounded in supplier input or local benchmarks? Is the team’s execution strategy reflected in the sequencing, resourcing, and risk structure?

Investors want to see that the team has thought about how the project will unfold—not just what it might look like. They care less about polished renderings and more about whether there’s a credible path to positive cash flow. When a study answers that, clearly and simply, it does its job.

How TMG Helps You Strike the Right Balance

At TMG, we work with clients to ensure their studies are complete—but not overbuilt. We review plans not just for what’s included, but for what should be left out. We help teams focus on defining scope, refining assumptions, and clarifying execution pathways—so investors see a study that’s grounded, actionable, and appropriate for the stage.

We also bring a field-tested perspective to design and planning. We understand how studies are interpreted by those who fund and deliver them—and we ensure your documents speak their language. When needed, we help unwind gold-plated scope, recenter teams around priority deliverables, and rebuild credibility before the next gate.

Our goal isn’t to polish studies. It’s to make them investable.
