How Lean Construction Benefits from DfMA

Construction industry buzzwords 'DfMA' and 'lean construction' have much to offer each other. Design for Manufacture and Assembly (DfMA), with the combined features of Design for Manufacture and Design for Assembly, employs the benefits of prefabricated construction modelling and design to benefit a growing move to incorporate lean construction concepts in building construction. So, looking at Design for Manufacture, the more important features are: Comprehending processes, capabilities and cost factors Choosing materials Estimating costs Modifying designs and models Important features of Design for Assembly include the following: Understanding when to move a part independently Knowing which parts need different materials or need to be separate Calculating part limitations for transport Knowing the assembly time for each part What DfMA does in essence can be summarised as follows.


Deciding the best way to manufacture parts and assemble them off site and transport them on site Uses prefabrication of components and modules Uses a process for the entire design team Used for customised buildings or mass production Now, what are the Italy Phone Numbers List general benefits of DfMA? Design that enables efficient construction Reduced costs On-time delivery of projects Improved quality, safety and easier maintenance of the building Reduced trades work on site Reduced impact on the public When DfMA is used for modular design, the following benefits may result: Reduced costs, interfaces, components, schedules, on-site trades Improved tolerance, processes which can be repeated Detailed specifications and orientations Easy access for maintenance, refurbishment and renewal Now, how does all this tie in with 'lean construction'? Well, the philosophy of lean construction maintains that processes much be continuously improved or updated and waste should be eliminated as much as possible. Combining the features of DfMA with the principles of lean construction results in several gains, such as: Deciding and working around constraints Analysing the build sequence Determining where to manufacture off site Integrating elements to on-site material.



Eliminating wasteful components Improving collaboration between trades Lean construction methods try to maximise value for customers while minimising waste. In the construction industry, where budgets, on-time deliveries and safety are crucial to a project's success, the lean methodology seems to be a desirable option. For lean construction, DfMA considers design before manufacturing. The lean approach requires certain processes that prefabrication and Building Information Modelling (BIM), especially prefabricated construction BIM, can help with, such as: A. Identifying Value for the Customer Establishing and earning the customers' trust early in the planning and design stage is important. In lean construction, owners, architects, engineers, general contractors, trade contractors and suppliers must work together to fulfil client objectives, provide advice and project realistic expectations. B. Defining the Value Clearly communicate the processes required to deliver this value. The requisite labour, data, infrastructure and materials for each part of the process are specified, and processes that do not add value are eliminated. Prefabricated construction modelling supplies an accurate view of the benefits of prefabrication of components or modules for all the project stakeholders.
