7 Overview of Singapore Construction Industry s Stakeholders Regulator Building Regulations, Construction Approvals Developer Project Owner Public Sector Private Developers Architect Specifications, Project Supervision Engineer Design, Supervision Contractor Procurement, Construction Supplier Material, Services 7

8 Work Flow Direction Typical Process Design & Construction Regulator Developer Architect Engineer Building Plan Structural / M&E Plan Approval Contractor Supplier Subcon Top down flow Instruction approach Productivity considered up front in design?! 8

9 Work Flow Direction Typical Process Design & Construction Alternate Proposal Regulator Developer Architect Engineer Building Plan Structural / M&E Plan Approval Contractor Supplier Subcon Complex process Time consuming Cost involved fees etc Project could be delayed Generally not attempted Productivity improvement? 9

10 Principles of Buildable Design: 3S Legislation required the Design Engineers to design the buildings in such a way that enables higher construction productivity, following the 3S principle Standardisation Simplicity Single integrated Grid repetition Component sizes Connection details Uncomplicated design Prefabricated DfMA Integrated single elements Off-site fabricated Pre-finished 10

17 DfMA Singapore s Approach Towards Superior Construction Productivity 17

18 Welcome to DfMA Concept To raise construction productivity and fundamentally change the design and construction processes, BCA encourages the industry to embrace the concept of Design for Manufacturing and Assembly (DfMA), where construction is designed such that as much work may be done offsite in a controlled manufacturing environment as possible.

23 PPVC (Prefabricated Prefinished Volumetric Construction) 23

24 What is PPVC? PPVC? Prefabricated Prefinished Volumetric Construction PPVC involves the assembly of whole rooms / units, complete with internal finishes, fixtures & fittings, that are produced offsite and installed onsite in a Lego like manner. 24

25 What is PPVC? 25

26 Conclusion 26

27 Singapore Construction is Evolving with DfMA Traditional method of construction is labour intensive and time consuming Productivity needs to be considered upfront in design DfMA paves the way for superior construction productivity PPVC is expected to become the new norm in Singapore construction Picture credit: BCA Gallery at BuildTechAsia
