Offsite Production Manager: The Modular Design Builder
Find out how an Offsite Production Manager oversees factory production of prefabricated M&E modules and what it takes to build a career in this growing field.

Q: What does one do as an offsite production manager?
A: Traditionally, we install mechanical and electrical (M&E) systems, which provide ventilation, lighting, power and water supplies, at the construction sites. In recent years, the sector has started building these systems and modules offsite (also known as prefabrication) in a factory plant environment, before transporting them to the site for installation. This approach speeds up the on-site installation process and enhances safety significantly.
An offsite production manager is responsible for factory operations, and liaises closely with suppliers and project stakeholders to ensure timely production and delivery of the prefabricated modules.
Q: What is the common misconception/s of what you do?
A: A common misconception is that offsite prefabrication is only suitable for specific types of buildings or locations. However, we’ve been demonstrating that modular construction can be applied to nearly all building types and locations, as long as Mechanical, Electrical and Plumbing (MEP) services are involved.
Q: How does one become an offsite production manager? Can you tell us more about your journey?
A: There are two paths one can take to be become a production manager. If you are technical or engineering trained, you can be a project manager focusing on the design of prefabricated modules, as technical expertise is essential to reviewing design feasibility and managing the setup of these modules.
For those interested in the M&E roles in the Built Environment sector, there are several routes to explore. Starting as an M&E consultant is common, where you design and advise on M&E systems. Alternatively, you could join a contractor to learn about traditional M&E systems and their installation. Another option is to work with a specialist firm like Tech Onshore MEP-Prefabricators (TOM), where you can gain experience in organising and implementing new M&E solutions in modern buildings.
Q: What is one interesting thing about your job?
A: People might assume that this job involves wearing safety boots and helmets and is physically demanding. This misconception may deter some, especially women, who might perceive the role as too rugged. However, most of the work has shifted away from construction sites to a manufacturing facility. This change makes the job much more manageable, with regular working hours and a more controlled environment.
Q: What do you enjoy most about your work?
A: The Built Environment sector is often perceived as lagging when it comes to innovation. On the contrary, countries like the United States and the United Kingdom have been advancing innovative building practices for decades and in Asia, we are also adopting more and more innovative building practices, especially in the past five years. At TOM, we are always seeking innovative solutions and having the opportunity to be among the first to introduce M&E off-site production in Singapore was thrilling.
