DFMA-oriented modular and parametric design and secondary splitting of vertical PC components

Area of Science:

• Construction Engineering and Management
• Building Science and Technology
• Materials Science and Engineering

Background:

• Standardization challenges in assembled building design and production hinder widespread adoption.
• Precast concrete (PC) components are crucial for assembled buildings but require improved design and manufacturing processes.
• Existing methods lack efficiency and integration across the entire building lifecycle.

Purpose of the Study:

• To apply the Design for Manufacture and Assembly (DFMA) concept to vertical PC components for assembled buildings.
• To investigate rapid modeling and whole-life cycle application of DFMA-oriented PC components.
• To propose and verify a modular, parametric design method integrating DFMA and Building Information Modeling (BIM).

Main Methods:

• Introduction of a modular design method combining parametric design and BIM.
• Development of a DFMA-oriented parametric design process for PC components, including secondary splitting of standard modules.
• Exploration of secondary development of DFMA and BIM, and module creation using family templates.

Main Results:

• A standardized design and production system for PC components was established.
• The design process for PC components became fast, accurate, and standardized.
• Integrated application of BIM was accelerated, enhancing digital collaboration in assembly construction.

Conclusions:

• The proposed DFMA-oriented modular parametric design method significantly improves the design and production of PC components.
• This approach reduces design costs and enhances overall efficiency and benefits for assembled buildings.
• The study validates the feasibility of integrating DFMA and BIM for a streamlined construction lifecycle.
