Why Skipping Front-End Engineering Is the Most Expensive Mistake in Capital Projects

In today’s manufacturing environments, capital projects are often large and complex, with execution teams facing extreme pressure to deliver measurable returns quickly. Faced with tight timelines and competing priorities, many organizations try to accelerate the path from idea to execution, often electing to skip Front-End Engineering (FEE) to “save time.”

But FEE isn’t simply an extra step in the process; it’s what makes successful execution possible. FEE bridges the gap between identifying a need and implementing the right solution, ensuring decisions are grounded in data and aligned across stakeholders from the start. When FEE is skipped, critical decisions are made based on assumptions rather than validated information.

This leads to increased risk across every aspect of the project, including gaps in scope, inaccurate cost estimates, and schedules that unravel once execution is underway. As these assumption-based decisions are corrected mid-project, changes compound, driving up costs, extending timelines, and eroding what can already be a compromised expected return on investment. Let’s dive into each of these risks more.

Scope Risk: Small Oversights Lead to Big Problems

One of the most common issues manufacturers face during capital projects is scope creep. The barrage of change orders usually seen in capital projects almost always starts with incomplete planning. Without FEE, it’s easy to overlook key elements of a project, leading to design and equipment selection gaps, unaccounted-for process steps, or overlooked quality and food safety requirements. These oversights don’t disappear or simply work themselves out. They show up later in the process as change orders, redesigns, and delays.

Scope risk becomes even more pronounced in multi-site or corporate-driven initiatives. A solution that looks good on paper may not account for real-world conditions at individual facilities. This was evident in a project we worked on for a global leader in the production and distribution of non-alcoholic beverages. While the company’s corporate engineering team made the decision to upgrade labeling systems company-wide to meet new case labeling requirements, it gave our team the flexibility to audit each of the eight sites and 33 lines individually as part of FEE.

Without this critical step, our design might have assumed all the equipment was installed at floor level, when in reality one site had lines running on a mezzanine, requiring a completely different upgrade approach. In another case for a site in California, our team had to avoid altering the structure of the line so that additional structural engineering to comply with local earthquake standards was not required.

Beyond technical considerations that impact scope, there’s also a people component that comes forward when FEE includes engaging stakeholders at each site. When site-level stakeholders aren’t involved early, important insights can be missed and long-term buy-in becomes harder to achieve. Bringing site teams into the process during FEE improves scope definition and results in smoother execution when it’s time to implement.

Cost Risk: Estimating Without Data Is Just Guessing

When it comes to cost estimation, even highly experienced teams can only go so far without using real data. When equipment costs can easily reach hundreds of thousands or even millions of dollars, working off assumptions rather than real quotes from vendors can have a major impact.

There can be multiple stages of FEE, with each stage providing a cost estimate that has accuracy reflective of the engineering effort required to develop the estimate. For example, a Conceptual Project Plan (CPP) provides a rough order-of-magnitude estimate within a defined accuracy range to help stakeholders determine if a project is financially feasible as scoped. A Definitive Project Plans (DPP) further refines the numbers identified in the CPP, usually to a higher level of accuracy, through vendor engagement and more detailed engineering.

When FEE is not used to develop early cost estimates, teams might budget based on past experiences and rough estimates. This is problematic because pricing for a prior project can be outdated. If a major piece of equipment is underestimated by 20 to 30 percent, the entire project budget can quickly fall apart.

The opposite risk also exists. If costs are grossly overestimated based on inflated assumptions, a project may appear less viable than it actually is, potentially preventing a good investment from moving forward.

Schedule Risk: The Timeline You Didn’t Plan For

One of the biggest drivers of a project’s timeline, and one where assumptions are frequently made, is equipment lead time. Organizations often assume equipment will be available when needed only to discover later that critical components actually have lead times of 40 to 50 weeks. This kind of delay can impact the entire business. For example, if a new production line or product launch is tied to a specific market window, not hitting a specified timeline can mean lost revenue, missed commitments, and strained customer relationships.

FEE helps mitigate this risk by identifying long-lead equipment early and incorporating realistic timelines into a project’s schedule. It also drives a broader evaluation of the entire execution plan and helps set expectations early for a project’s schedule. Without this level of planning, schedules are often overly optimistic and difficult to recover once execution is underway.

FEE Creates a More Realistic Path Forward

Skipping FEE may seem like a way to accelerate progress, but it often leads to the opposite outcome with more uncertainty, risk, and costly surprises. This is because without FEE, scope is often incomplete, cost estimates are little more than educated guesses where the margin for error can be significant, and schedules are typically overly optimistic.

By investing in FEE services such as assessments, CPPs, and DPPs, manufacturers gain the clarity needed to more accurately define scope, validate costs, and build realistic schedules before committing capital. As a result, companies can avoid the many hidden costs of capital projects that come with scope creep, change orders, and timeline extensions.
