Roundtable Discussion: Technical Challenges and Opportunities of Adopting MiMEP
The Roundtable Discussion at the Summit focused on the successful implementation of MiMEP in the private sector, using Lee Garden Eight as a key case study. Panellists highlighted the innovative design and procurement strategies employed in the Project and shared lessons for broader adoption of MiMEP in future projects. They discussed opportunities for MiMEP manufacturers in the Greater Bay Area (GBA), supported by tax rebate mechanisms, and emphasized the need for professional development in DfMA and on-site installation skills. The discussion also explored the positive impact of sustainable practices on the office leasing market, where tenants increasingly prioritise eco-friendly and efficient spaces.
Ir. Brian Cheng, Executive Director and Managing Director of ATAL Engineering Group, reflected on the application of MiMEP in Lee Garden Eight project. “ATAL has been a pioneer in MiMEP, and our experience with Lee Garden Eight has demonstrated how early-stage integration of these systems can dramatically improve efficiency and on-site safety. This is the future of construction, and we are proud to be at the forefront.” ATAL established working guidelines for the MiMEP when it was first applied. Over time, these guidelines have been continuously improved and optimised based on practical application experiences. Today, this approach has evolved into a systematic solution. With the support of their in-house “MiMEP Design and Manufacturing Centre” and “MiMEP High Productivity Research Centre,” ATAL is confident in maintaining strict quality control over each MiMEP component. Ir. Cheng believed that the Greater Bay Area (GBA) offers significant potential for MiMEP manufacturing, where manufacturers can benefit from economies of scale and government support. The trade and export tax rebate mechanisms in the GBA are particularly beneficial, allowing manufacturers to reduce costs and make MiMEP components more competitive. These opportunities, if leveraged correctly, can lower the investment risks and enhance returns for manufacturers, further driving the growth of MiMEP in Hong Kong and the region.
Mr. Kenneth Ma, Deputy Managing Director of Hip Hing Construction Company Limited, expanded on the unique procurement strategies and coordination mechanisms employed in Lee Garden Eight. “The introduction of the iMEP role by Hysan at Lee Garden Eight was instrumental in enabling the effective implementation of MiMEP. This innovation required us, as the main contractor, to rethink and refine existing procurement processes and workflows to ensure the successful integration of modular components. By centralising all assembly in off-site facilities, we eliminated the inefficiencies of multiple trades working independently on-site. This not only sped up the project timeline but also reduced risks and improved safety. To fully realise the potential of MiMEP, we need to invest in training and professional development. Existing programmes in DfMA are a good start, but we need to expand these to include on-site installation skills specific to MiMEP modules. This will ensure that the workforce is equipped to handle the complexities of modular construction, reducing errors and ensuring smoother project execution.”
Lee Garden Eight marks a major strategic expansion of Hysan’s core footprint, adding approximately 1.1 million square feet to its asset portfolio. The project will bring a multitude of benefits to the community with a number of sustainable features, including 60,000 sq ft of green landscape in the form of an urban park, footbridge connections to enhance connectivity and walkability, as well as measures to enhance resource efficiency in areas such as energy consumption, renewable energy, waste management and water conservation to provide an ecofriendly and comfortable environment for tenants and visitors. Designed to adhere to the highest sustainability standards, the project incorporates 85% MiMEP adoption—one of the highest rates in Hong Kong’s private sector—setting a new benchmark for sustainable construction. With over 7,000 MiMEP modules, the project effectively addresses critical industry challenges such as labour shortages and construction inefficiencies. Through off-site fabrication, the project achieved remarkable results: a 70% reduction in on-site construction waste, a 70% cut in carbon emissions, and a 5% overall reduction in E&M costs. Additionally, the assembly can be completed in an impressive timeline that is three months faster than traditional construction methods, showcasing the efficiency and innovation enabled by MiMEP. With an expected opening in the third quarter of 2026, the Project aims to obtain the highest ratings of green and wellness certificates internationally and locally. Notably, over 2.7 million square feet of Hysan’s GFA portfolio in Causeway Bay is already certified as green buildings, further reinforcing the company’s commitment to sustainability.
