INTRODUCTION  \nThis information kit aims to update the industry on regulatory developments to Prefabricated Mechanical, Electrical & Plumbing Systems (Prefab MEP) adoption, share the learning points and good practices from completed and ongoing Prefab MEP projects, and serve as a guide with the useful information on Prefab MEP.  \nDifferent sections of this kit may be more applicable to certain stakeholders. The table below summarises the contents and respective target audience.  \nPrefab MEP Information Kit Version 1 – 2026  3   \n2. PROCUREMENT  MATTERS  \n2.1 Early Involvement of Prefab MEP Specialists  \nThe early decision to adopt Prefab MEP modules in a project facilitates greater continuity of design and maximises productivity gains. It is imperative for developers to engage builders, MEP contractors and PMEP specialists at the earliest possible stage. This early collaboration ensures the incorporation of inputs from all parties, leading to a more buildable and coordinated solution.  \nBelow are some typical procurement models adopted for construction projects:  \na. Design and Build (D&B)  \nb. Design Development and Build (DDB)  \nc. Design Bid Build (DBB)  \nFor more detailed information on the different types of procurement models in Singapore, as well as examples of overseas procurement models, please refer to Chapter 2 of the Prefab MEP Guidebook Version 2.  \nBuilder should engage the MEP specialist early to ensure a more accurate tender bid.  \nFire Subcontractor  \nPrefabricated MEP Specialist*  \nDeveloper  \nBuilder  \nConsultant  \nACMV Subcontractor  \nElectrical Subcontractor  \nP&S Subcontractor  \n*Prefabricated MEP Specialist refers to the party responsible for carrying out prefabricated MEP works, including coordination, design, fabrication, and installation. There does not necessarily need to be a dedicated specialist; this role can also fall under the scope of one of the subcontractors.  \nFigure 1: Design and Build Model  \n2.2 Contractual Considerations  \nUnlike conventional projects where M&E subcontractors work independently, adopting a Prefab MEP system requires greater collaboration and coordination among all relevant parties, as services are integrated within the same modules. Therefore, when calling for tenders for projects utilising Prefab MEP, clients should consider the following points:  \nProcurement Model Selection  \nChoose a procurement model that allows for the early involvement of Prefab MEP specialists during the design stage. Their expertise can help anticipate and address potential challenges early, enhancing overall project productivity.  \nSi","cbCaieaCAanji4Gm","https://ap.wps.com/l/cbCaieaCAanji4Gm","pdf",6825844,26,"English","# 1.
