What is MEP Prefabrication?<\/h5>\n

Prefabrication in MEP systems is the practice of manufacturing\/assembling components of building services in a factory or other manufacturing site and transporting complete assemblies of MEP components or sub-assemblies to the relevant construction site. These assemblies are often known as MEP modules or prefabricated MEP modules. MEP prefabrication can be applied to buildings, such as data centres, where there are standard sizes of MEP components within structures. In commercial buildings, such as hotels, offices and shopping malls, due to variations in design and heating\/cooling loads, modularisation, or the process of manufacturing tailor-made MEP components, is the perfect solution for MEP systems.<\/p>\n

<\/div>\n
Types & Examples of MEP Prefabrication<\/h5>\n

A. Prefabricated Components:<\/strong> <\/p>\n

\n
\n
\n
\n
    \n
  • Flexible water pipes<\/li>\n
  • Pre-insulated aircon ducts<\/li>\n<\/ul>\n<\/div><\/div>\n
    \n
    \n
      \n
    • Plug and play cables<\/li>\n
    • Flexible sprinkler droppers<\/li>\n<\/ul>\n<\/div><\/div>\n<\/p><\/div>\n<\/p><\/div>\n

      B. Prefabricated Sub-assemblies or Modules: <\/strong><\/p>\n

      \n
      \n
      \n
      \n
        \n
      • Horizontal ceiling modules with pipes, cable trays, trunking, etc. <\/li>\n
      • Vertical ceiling modules with pipes, cable trays, trunking, etc. <\/li>\n<\/ul>\n<\/div><\/div>\n
        \n
        \n
          \n
        • Pumps, compressor modules, etc.<\/li>\n<\/ul>\n<\/div><\/div>\n<\/p><\/div>\n<\/p><\/div>\n

          B.1<\/span> Horizontal Ceiling Modules <\/strong> <\/p>\n

          A horizontal ceiling module should aim to include most, if not all, of MEP services components in the ceiling. Components that can be included are Sprinklers, Chilled water supply and return pipes, Condensate drain pipes, Sanitary drains, Plumbing, Town gas, Medical gas systems, Electrical, extra low voltage cabling with trunking, tray or cable ladders (typically, cables are drawn only after installation of modules on site to minimise cable jointing), Air-conditioning\/mechanical ventilation ductwork, Light fixtures<\/p>\n

          B.2<\/span> Vertical Riser Modules <\/strong> <\/p>\n

          A vertical riser module comprises of vertical riser ducts and pipes. The vertical services in each riser module can be installed horizontally at ground level in the factory and can branch out to multiple floors. A riser module can be installed prior to, and independently of, the erection of riser shaft block walls. Also, riser modules can be lowered into the riser shaft through designated openings in the top floor. Therefore, lifting lugs and brackets should be incorporated in vertical riser module design.<\/p>\n

          C. Prefabricated Sub-assemblies with Architectural\/Structural Components <\/strong> <\/p>\n

          \n

                  MEP Prefabrication Process & Stakeholders<\/h4>\n

                  \"\"<\/p>\n

                  Benefits of Prefabrication<\/h5>\n
                  \n
                    \n
                  • Specialised jobs \u2013 high scope of minute modifications<\/li>\n
                  • Time management \u2013 better time scheduling, as building various components can be done simultaneously<\/li>\n
                  • Mass production is easier and faster<\/li>\n
                  • Skilled workforce \u2013 technically qualified personnel at manufacturing facility<\/li>\n
                  • Safer work environment \u2013 controlled and safe work environment at both on-site and off-site manufacturing plants<\/li>\n
                  • Less worker traffic on site \u2013 leading to safer jobsites<\/li>\n
                  • Less weather dependency \u2013 as prefabricated components are manufactured within a factory<\/li>\n
                  • Easier vendor management \u2013 single supplier throughout design, construction, testing and maintenance<\/li>\n<\/ul>\n<\/div>\n
                    Requirements for Modular MEP Construction<\/h5>\n

                    Typically, challenges in modular MEP construction may occur during the latter stages of design or even after construction commences. These challenges can be largely avoided with effective and precise design early on. For increased productivity and reduced reworks, the drawings have to be accurate. Minor oversights could have major consequences for fabricators and installers. MEP prefabrication needs:<\/p>\n

                        BIM in MEP Modular Construction<\/h5>\n

                        Multi-trade prefabrication requires a significant amount of pre-planning and design coordination. Building Information Modelling (BIM) is ideal for design coordination, construction planning, on-site delivery planning, clash detection and fabrication planning in modular construction. BIM improves communication between different stakeholders in the project and helps to get designers, construction teams and maintenance teams involved from the initial stages.<\/p>\n

                        Is outsourcing BIM modelling a better option?<\/h5>\n
                        \n
                          \n
                        • Outsourced companies can provide prefabrication drawings, 3<\/span>D models and conversions of paper sketches to detailed design drawings.<\/li>\n
                        • Outsourced companies offer high quality services, accurate BIM models and CAD drafting services, so that more time can be channelled into other key areas of construction.<\/li>\n
                        • Firms that outsource these services can be sure of the technically qualified personnel delivering their services, since offshore companies take great care to retain reliable professionals.<\/li>\n<\/ul>\n<\/div>\n
                          Future of Prefabrication<\/h5>\n

                          The prefabrication industry is still in its infancy. We expect to see it moving towards the use of advanced robotic manufacturing and assembly, which will allow a greater number of projects to be completed with the same amount of labour, providing better cost savings and better safety levels.<\/p>\n","protected":false},"featured_media":2882,"template":"","format":"standard","categories":[9,11],"class_list":["post-895","articles","type-articles","status-publish","format-standard","has-post-thumbnail","hentry","category-articles","category-engineering"],"acf":[],"yoast_head":"\nPrefabrication in MEP Systems -
