Why Design for Manufacturing and Assembly (DfMA) is an advantage for Builders and Developers

The construction industry across the globe is going through a phase of transformation. The latest technological innovations, such as design for manufacturing and assembly (DfMA), are gradually replacing conventional practices. 

Understanding the concept and practical benefits of design for manufacturing and assembly (DfMA) for commercial builders is critical to bringing value to existing and new construction projects.

Design for Manufacturing and Assembly (DfMA)

Conventionally, most building designs focus on aesthetics rather than buildability, usability, and investment return. The concept of Design for Manufacturing and Assembly (DfMA) factors in these critical values and combines them with beautiful designs to ensure developers get the most value for their construction projects.

In Design for Manufacturing and Assembly (DfMA), every aspect of the building is broken down into prefabricated building components like walls, columns, beams, stairs, and in some instances, complete 3D bathrooms or rooms. The construction, design, and structural engineering teams focus on optimizing each component’s design to ensure efficiency in material management, cost, and on-site assembly and improvement in durability, stability. 

Once the component designs are value engineered and approved, they are assembly line produced in the factory as per a pre-assigned construction schedule.

Improved Project Management

Adopting Design for Manufacturing and Assembly (DfMA) enhances transparency and efficiency across the construction project. Production of prefabricated building components is monitored at the factory level with stringent quality checks. Prefabricated building components are manufactured on schedule and delivered to sites just-in-time for assembly, creating a seamless construction process.

The application of prefabricated building components has thoroughly changed the dynamics of managing construction timelines and has been critical in ensuring on-time project delivery.

Simplification by Reducing Unique Building Components

Utilizing the concept of Design for Manufacturing and Assembly (DfMA) helps reduce the number of unique components in the building.

The focus is to standardize prefabricated building components, efficiently offsite factory manufacture each element, and deliver them on-site for assembly. There is no building work done on the site to ensure minimal disruption and waste to simplify the entire construction process

Controlled Onsite Assembly of Construction Projects

Project Managers have complete control and transparency for managing construction projects. Since all prefabricated elements are factory manufactured, there is a minimal dependency on on-site labor, weather conditions, or other site-based constraints. Katerra makes building components, MEP systems, finished bathroom pods, and modular rooms as prefabricated structures. Precision factory manufacturing of prefabricated structures ensures the simple execution of the construction project on-site.

Better Value and No Cost Overruns

Design for manufacturing and assembly (DfMA) brings better value for construction projects by reducing cost overruns and ensuring on-time completion, minimizing an increase in variable costs. Today delay in completing projects is a severe cost to companies – costing revenue generation, investment returns, and legal complications. Implementing Design for manufacturing and assembly (DfMA) ensures that construction is completed on time, bringing in better value and investment returns.

Safety & Reliability

The process of construction adopting prefabricated building components is much safer and reliable than the conventional methods. Since all building components are factory manufactured and not based on manual skill sets, the product has better quality and durability. Factory produced elements also use better quality material and skill manship combined with technology and automation to deliver a higher quality product.

Katerra has been innovating and promoting optimized component design and value-engineering in their construction projects since its inceptions. We deliver technology-driven solutions based on the design for manufacturing and assembly (DfMA) philosophy, enabling us to assembly-line factory manufacture prefabricated building components in our state-of-the-art factories. The combination of design for manufacturing and assembly (DfMA) and Offsite Manufacturing has ensured we deliver better, faster, and more sustainable construction projects for our clients, including Microsoft, Infosys, Bosch, Embassy, across the Middle East and Asia.
