Modularization, or skid-mount construction, is increasing in popularity and demand as an alternative to traditional construction. This approach involves relocating large portions of an industrial project from a construction site to a controlled environment, such as a fabrication shop. And it can provide several benefits, including high-quality structural integrity as well as significant efficiencies. General estimates suggest that implementing modular process systems where possible can save up to 25% on total project costs. 

This article will clarify common misconceptions about modular construction cost savings. It will consider this approach's practical and financial advantages when applied in specific use cases, such as projects in remote locations or with poor or restricted access to labor on site. 

It’s also important to note that traditional construction is still the preferred method for larger projects that require extensive on-site construction. Deciding between a traditional,  modular, or hybrid approach should involve an assessment of your capital project’s goals, challenges, and requirements. H+M can support any of these execution methods.

Modular and Traditional Construction Comparison

Modular Construction

Traditional Construction


Efficient production leads to potential savings. Steel frames and transport add cost.

On-site labor/material costs may increase expenses.


Pre-fabrication can speed up completion.

On-site construction may extend timelines.

Quality Control

Controlled environments enhance precision.

Quality challenges include external conditions and logistics of inspectors at site at the right points in time.


Potential for reduced on-site labor costs.

Requires skilled on-site workforce.

Material Costs

Savings from procurement offset by transportable materials.

Costs affected by waste and procurement strategies.

How Does Modular Construction Save Money?

Modular construction is increasingly recognized for its cost-saving potential (up to 25% of total project costs). This process can sometimes, depending on the project, minimize labor and material waste, with a controlled environment that enhances material use and reduces time and money spent on on-site labor and construction. 

Modular construction can also be especially valuable in today’s labor market, where it can be difficult to find and retain skilled workers. Modularization’s efficiency, less waste, and reduced weather-related challenges can provide savings in some cases. However, the extent of the savings will depend on specific project requirements and challenges.

How Much Time Does it Save? 

The on-site construction process involves assembling pre-fabricated modules encased in steel frames and connecting them to essential services or other modular units. This process is typically handled by smaller teams with rapid assembly. 

For some capital projects, this approach can outpace traditional construction. Acceleration is primarily due to the pre-fabrication of components in a controlled factory setting, which reduces the volume of on-site work required, or allows on site work to occur simultaneously, while eliminating and reducing potential delays (such as rework). 

Modular Construction Cost Savings:

Prefabrication, Preassembly, Modularization, and 

Off-site Fabrication (PPMOF)

Direct Benefits of PPMOF

  • Quicker project completion
  • Enhanced productivity
  • Improved Safety
  • Higher Quality

Industry Challenges Addressed

  • Workforce availability
  • Budget constraints
  • Reduced on-site labor (improving safety and logistics)

Is Modular Construction Better?

It’s important to recognize that traditional construction is still the preferred method of approach for large capital projects that require on-site work. Modularization can only be considered to be advantageous when applied to overcome specific challenges.

Modularization’s advantages center on efficiency, quality control, and predictability. Identifying optimal levels of modularization and how the approach will align with overall project development should be key considerations. It’s highly recommended to conduct a thorough assessment to ensure that modularization maximizes benefits while meeting your project's specific requirements and goals.

H+M Modular Construction Cost Savings

Modular construction can be a viable alternative to traditional construction in some cases, leading to benefits such as cost savings, time efficiency, and quality control. However, it can also pose design adaptation and logistical challenges. Working with the right EPC contractor with significant design-build experience will help ensure your project benefits from taking the right approach. 

Detailed planning and expertise across multiple engineering disciplines are required to realize the benefits of modularization. Front-end planning, 3D modeling, fabrication, procurement, and logistics are all part of making the approach as efficient and effective as possible.
