DfMA provides a better quality, a time-managed solution and a safer construction site as more activities are carried out offsite. DfMA comes in many forms – the principal focus of this article is Prefabricated Mechanical Electrical and Plumbing (MEP) Systems.  \nThrough the implementation of DfMA for Prefabricated MEP Systems, major MEP construction processes which are traditionally labour intensive will be carried out at off-site facilities. The respective prefabricated MEP modules which are complete, with two or more MEP services, will be transported to the construction site for final assembly, inspection, installation, testing and commissioning.  \nTYPES OF PREFABRICATED MEP SYSTEMS  \nThere are various types of Prefabricated MEP modules available in the market including horizontal ceiling modules, vertical riser modules and plant modules. The potential areas of application are as follows:  \n\n| Residential\u003Cbr>Commercial\u003Cbr>Hotel\u003Cbr>Office\u003Cbr>Industrial\u003Cbr>Healthcare\u003Cbr>Institutional\u003Cbr>Data Centre |  |  |  |  |  |  |  |  |\n| --- | --- | --- | --- | --- | --- | --- | --- | --- |\n| Prefabricated Duct | 􀀹 | 􀀹 | 􀀹 | 􀀹 | 􀀹 | 􀀹 | 􀀹 | 􀀹 |\n| Prefabricated Horizontal or Vertical MEP Module including Pipes, Cable Trays, Ducts | 􀀹 | 􀀹 | 􀀹 | 􀀹 | 􀀹 | 􀀹 |  | 􀀹 |\n| Prefabricated Riser Module | 􀀹 | 􀀹 | 􀀹 | 􀀹 | 􀀹 | 􀀹 | 􀀹 | 􀀹 |\n| Prefabricated Horizontal Module including ceiling board, duct, pipe, lightings, etc |  | 􀀹 |  |  |  | 􀀹 |  | 􀀹 |\n| Prefabricated Plant Module including Pumps, Pipes, Valves, Pump Skid | 􀀹 | 􀀹 | 􀀹 | 􀀹 | 􀀹 | 􀀹 | 􀀹 | 􀀹 |\n| Prefabricated MEP Module integrated with Work Platform/ Catwalk |  | 􀀹 | 􀀹 | 􀀹 | 􀀹 | 􀀹 | 􀀹 | 􀀹 |\n\nBCA’S GUIDELINES FOR DFMA FOR PREFABRICATED MEP SYSTEMS  \nPrefabricated MEP Good Industry Practices Guidebook  \nThe Building and Construction Authority (BCA) of Singapore released a Prefabricated MEP GIP guidebook in April 2018 to help practitioners to have a better understanding on prefabricated MEP modules and its benefits. The guidebook draw references from overseas project experiences and sets out some good industry practices guidance (from upfront planning, procurement and maintenance) on how such systems could be incorporated prefabricated MEP systems in the development.  \nCode of Practice on Buildability 2017  \nThe Buildable Design Appraisal (BDAS) framework was further enhanced in May 2017. To promote designs giving considerations on DfMA, and encourage wider adoption of MEP Systems with higher productivity gains, the Code of Practice on Buildability 2017 allocated additional points to the following new MEP modules with at least 65% coverage in the project.  \n\n|  | N Value |  |\n| --- | --- | --- |\n|  | Percentage of Coverage |  |\n|  | ≥ 65% to \u003C 80% | ≥ 80% |\n| Prefabricated MEP modules integrated with work platform/ catwalk+ | 3.00 | 5.00 |\n| Prefabricated MEP modules e. g. pipes, cable trays/trunking etc+ | 2.00 | 4.00 |\n| Prefabricated MEP plant modules e.g. pump, compressor etc+ | 2.00 | 4.00 |\n| + denotes items newly introduced in COP on Buildability 2017\u003Cbr>Source: BCA Code of Practice on Buildability – Table 3 Design for Manufacturing and Assembly technologies (DfMA)– N Value |  |  |\n\nPoints for other MEP modules with relatively lower class of DfMA as compared to those stated above has been adjusted in COP 2017 to commensurate the potential manpower savings expected from their adoption.  \n\n|  | N Value under COP 2017 |  | N Value under COP 2015 |  |\n| --- | --- | --- | --- | --- |\n|  | Percentage of Coverage |  | Per","cbCaiewKPngY5QdV","https://ap.wps.com/l/cbCaiewKPngY5QdV","pdf",1227377,"English","# Introduction\n# What is DFMA – MEP System\n# Types of Prefabricated MEP Systems\n# BCA’s Guidelines for DFMA for Prefabricated MEP Systems\n## Prefabricated MEP Good Industry Practices Guidebook\n## Code of Practice on Buildability 2017\n# Accreditation\n## Building Innovation Panel (BIP)\n## Prefabricated MEP Manufacturer Accreditation Scheme\n# Cost and Time Implications","[{\"question\":\"What does DFMA mean in the context of MEP systems?\",\"answer\":\"DFMA integrates factory-manufactured building components delivered to the site for assembly.
