Modular Manufacturing and VDC Are Redefining Heavy Industrial Construction

By Matt Wilson, Project Executive of Industrial – The pipeline of heavy industrial construction in the United States has never been larger or more demanding. Driven by a wave of reshoring, domestic manufacturing investment, and landmark federal legislation, companies like Samsung, TSMC, Hyundai, Panasonic, and Ford are committing tens of billions of dollars to new production facilities across the country. Samsung alone is investing $17 billion in semiconductor fabs in Taylor, Texas. TSMC has committed more than $65 billion to three fabrication plants in Arizona. Ford and SK On are building a $5.8 billion EV battery campus in Kentucky. The scale is extraordinary. And it is exposing a hard truth about conventional construction: the traditional field-built model cannot keep pace.

The Labor Math Doesn’t Work

The construction industry entered 2025 needing 439,000 additional workers just to meet existing demand. This number rose to approximately 500,000 by 2026, according to workforce data tracked by the Associated Builders and Contractors. The shortage is structural, not cyclical. Roughly 41 percent of today’s construction workforce is projected to retire by 2031, and 92 percent of contractors already report difficulty filling open positions. Forty-five percent have experienced project delays in the past year attributable directly to labor gaps.

For heavy industrial projects, which require dense concentrations of skilled trades working simultaneously across complex systems, these numbers are especially acute. A semiconductor fab or EV battery plant is not a building; it is a precision manufacturing environment embedded inside a building, with mechanical, electrical, process piping, and structural systems intertwined at every level. Staffing that work through traditional field sequencing, in the volume the current pipeline demands, is increasingly untenable.

Modular Manufacturing’s Moment

The global modular construction market was valued at approximately $90 billion in 2024 and is forecast to reach $155 billion by 2033, growing at a compound annual rate of 6.2 percent, according to Astute Analytica. In North America alone, 255 modular manufacturers are currently operating, with individual facilities capable of producing up to 25,000 square feet of assemblies per week. The sector has attracted more than $2.2 billion in investment over the past decade, and adoption is accelerating as owners and contractors recognize the operational advantages.

Modular manufacturing in the industrial context means far more than prefabricated pipe spools or pre-assembled ductwork. It means engineering entire functional systems, including mechanical rooms, process skids, electrical distribution assemblies, utility infrastructure modules, as self-contained units that are built, inspected, and tested in a controlled fabrication environment before they ever arrive at the job site. Research by McKinsey & Company found that mature modular approaches can reduce manpower requirements by up to 40 percent and compress construction timelines by as much as 50 percent at scale. Laing O’Rourke, one of the global leaders in offsite manufacturing for complex industrial and infrastructure projects, reports that its Design for Manufacture and Assembly (DfMA) model, which moves 70 percent of construction activity offsite, consistently delivers 60 percent efficiency gains and 30 percent schedule acceleration versus comparable field-built projects.

VDC Is the Engine That Makes It Run

None of the gains modular manufacturing promises are achievable without Virtual Design and Construction (VDC) as the foundation. A module is more than a piece of a building moved to a factory floor. It is a precisely engineered unit whose dimensions, connection points, structural loads, MEP routing, and installation sequence must be resolved completely before fabrication begins. That level of coordination cannot be managed on a 2D drawing set. It requires a fully clash-free, multi-discipline 3D model in which every trade works within the same digital environment.

Industry research consistently validates the return on that investment. Studies on BIM implementation in complex construction projects show a 10 to 20 percent reduction in total construction costs, a 40 percent reduction in rework, (which traditionally consumes up to 12 percent of a project’s total budget) and project delivery improvements ranging from 20 to 50 percent faster than conventional schedules. Clash detection alone delivers a return of eight to ten dollars for every dollar invested, according to analysis of major infrastructure projects. Firms like Skanska and Bouygues Construction have embedded VDC at the center of their modular strategies, using coordinated models to drive both fabrication sequencing and site logistics in parallel, allowing factory production and site preparation to run simultaneously rather than sequentially.

What This Means for Industrial Owners

For owners driving the current wave of domestic manufacturing investment, including battery makers, chipmakers, food and beverage producers, chemical and process manufacturers, the implications are direct. A modular-enabled project is not only a faster project. It is a fundamentally more predictable project. When scope is locked in the model before fabrication begins, field change orders driven by coordination failures are largely eliminated. When systems are tested in the shop rather than commissioned in the field, startup timelines compress. When work migrates from scaffolding and elevated platforms to controlled factory benches, safety incident rates fall.

Those schedule gains carry real business value. For a manufacturer racing to bring a new production line online, every week of schedule compression represents revenue, market share, and competitive position. The companies funding today’s industrial construction boom did not invest billions to wait.

Getting the Conditions Right

Realizing those benefits, however, requires conditions that many projects fail to establish. Modular strategy must be integrated from the earliest stages of project development and not retrofitted into a conventionally designed project midstream. The design team, construction manager, and owner must align on modular scope, transport logistics, and site sequencing before design advances, because decisions made at 30 percent design are extraordinarily difficult and expensive to reverse at 60 percent.

It also requires construction partners with genuine, embedded VDC capability. At Holland Construction Services, our industrial team uses fully coordinated BIM from preconstruction through commissioning, not as a documentation tool, but as the operational backbone of module design, fabrication management, and site sequencing. In our experience, the projects that capture the full promise of modular delivery are the ones where the model is built before the schedule is set, and where every stakeholder, owner, designer, contractor, and fabricator is working from the same digital environment.

The Direction of the Industry

The forces accelerating modular adoption, a constrained labor pool, unprecedented industrial investment, compressed owner schedules, and maturing VDC technology, are not temporary. They are structural features of the construction landscape for the foreseeable future. Firms like Laing O’Rourke and Skanska have spent years building offsite manufacturing infrastructure precisely because they recognized this direction early. The rest of the industry is following.

For heavy industrial owners making multibillion-dollar commitments to U.S. manufacturing capacity, the question is no longer whether to pursue modular delivery. It is whether their construction partners have the modeling rigor, the fabrication relationships, and the sequencing discipline to execute it at the level the investment demands. The answer to that question will define which projects open on schedule and which ones don’t.
