DfMA Benefits in Construction

Key Benefits of DfMA

• Shorter construction periods due to off-site prefabrication, leading to less manpower on-site.
• Improved workmanship derived from strict quality control in prefabrication factories.
• Reduction in community disruption as on-site construction work is minimized.

DfMA Impact on the Industry

• Offers potential as a game changer for the building and construction industry.
• Enhances productivity through a streamlined value chain.
• Represents a paradigm shift in design, construction, and maintenance practices.

Achievements and Progress

• 102 GPE projects have integrated Building Information Modeling (BIM).
• 115 projects complied with mandatory BIM e-submission requirements.
• Investment of $17 million into 650 firms resulted in an average efficiency gain of 21.5%.
• Training efforts included 7000 professionals and 2000 students prior to graduation.

Initial Assessment of BIM Adoption

• Developers shown to be detached from the BIM process and lack collaboration.
• Consultants struggle with e-submission focus and time constraints for design coordination.
• Main contractors receive low-quality models and underutilize BIM for issue resolution.
• Specialist subcontractors commonly lack BIM skills, hindering effective management.

Current Industry Concerns

• Absence of clear leadership in collaborative BIM practices raises questions on responsibility.
• Challenges in justifying ROI for adopting collaborative BIM approaches.
• Issues with redundant work processes and productivity in current BIM adoption practices.
• Concerns about the effectiveness of existing 3D models leading to extra rework and inefficiencies.

Oliver Wight “Class A” Methodology

• A framework to enhance the maturity of integrated business planning processes.

Value Configurations Overview

• Value Chain: Focuses on transforming inputs into products.
• Value Shop: Aims to resolve customer issues through solutions.
• Value Network/Web: Enables exchanges between customers through relationships.

Facilitating VDC Processes

• Implementation of Big Room scenarios for better coordination and clash detection.
• Utilization of Virtual Reality (VR) for design reviews and visualization.
• Conducting Integrated Concurrent Engineering (ICE) sessions to improve collaboration.

Positive and Negative Effects of Implementing VDC

• Positive outcomes include reduced Requests for Information (RFIs), improved predictability, and decreased rework.
• Negative effects show minimal collaboration improvement and reluctance among subcontractors to adopt BIM.

Improvement and Collaboration Achievements

• Although tedious reporting processes have been minimized, true collaborative frameworks remain insufficient.
• Built-in analytics improve project tracking by anticipating delays and cost overruns.
• Fostering data-driven productivity is essential for collaboration across value chain partners.

Current and Future Plans for RAPID Adoption

• Over 20 developers engaged in the RAPID pilot phase (2023-2024).
• More than 10 developers have committed to adopt RAPID solutions.
• Future plans include enhancing functionalities for the entire development life cycle and targeting international markets.

Targeted Organizations for RAPID Subscription

• RAPID Plus: Aimed at township planners and mixed development projects.
• RAPID Standard: For commercial and standard IDD projects.
• RAPID Lite: Designed for boutique developers and small/medium enterprises.

Critical Success Factors for the Initiative

• Full involvement from all stakeholders including government, developers, and contractors.
• Mature technology platforms must be established, focusing on 3D design and high-speed networks.
• Creation of a trusted digital environment for secure information sharing.
• A dedicated industry champion is needed to lead initiatives with government support for regulatory and funding assistance.
• A sustainable business model is required to ensure growth and viability.
