MiMEP Three-in-one Integrated Solution to Save Cost and Enhance Efficiency
2025-10-20
The Multi-trade integrated Mechanical, Electrical and Plumbing (MiMEP) approach enhances construction efficiency, quality, and safety through off-site prefabrication and modular installation, making it ideal for Hong Kong’s high-density and fast-paced development needs. This year, the EMSD further introduced the MiMEP three-in-one solution, which integrates MiMEP, open Building Information Modelling (open BIM) standards, and the Building Information Modelling–Asset Management (BIM-AM) system. This approach was applied to 24 repair, maintenance, alteration and addition (RMAA) pilot projects, achieving remarkable results. Building on our hands-on experience, we presented a proposal titled “Era of Digitalisation and Sustainability: open BIM with Asset Management for MiMEP Projects towards New Quality Productive Forces”, which earned the Grand Award in the Technology Solution Category at the Hong Kong openBIM/openGIS Awards 2025.
This three-in-one solution combines MiMEP with BIM, significantly enhancing project efficiency and management effectiveness. During the planning phase, the engineering team uses BIM to create a site environment model and simulate transportation, lifting, and assembly processes of prefabricated modules. At handover, the BIM model contains complete E&M asset information to help clients digitise asset management. Additionally, using the open BIM data format ensures smooth communication and data sharing among the engineering teams throughout construction, handover, and maintenance. This approach eliminates the need for clients to invest in multiple software licence and related training costs, helping to lower the entry barrier for using BIM.
The EMSD has implemented 24 pilot projects, including installation and replacement of various E&M systems at hospitals, sports centres, and government buildings, earning high praise from clients. Data shows MiMEP can reduce on-site installation time by about 60%, making it especially suitable for venues like hospitals that operate continuously, as it minimises disruption and enhances site safety. Additionally, the E&M equipment is pre-assembled in the factory, significantly reducing on-site assembly work and enhancing construction site safety. Combining MiMEP with BIM reduces construction errors, improves project quality, and extends equipment lifespan. The BIM-AM system helps clients clearly understand asset conditions, facilitating maintenance and lowering operational costs.
Furthermore, this three-in-one solution will promote wider adoption of BIM, encouraging more small and medium contractors to use BIM-AM and open BIM technologies, driving digital transformation in the industry and fostering the development of new quality productive forces.

The District Cooling System (DCS) : The Green Industry Harmonize Urban Planning with the Environment
2026-08-12
The District Cooling System (DCS) not only enhances the energy efficiency of buildings, leveraging economies of scale and enabling centralized management to reduce capital and operational costs, more importantly it can seamlessly integrate design with the environment through early holistic urban and architectural planning. This reduces the heat island effect and liberates additional space for sustainable development, transforming green dreams into reality. Drawing on the successful experience of the Kai Tak District Cooling System, the Electrical and Mechanical Services Department envisions a collaborative future with the public to create a more comfortable and sustainable green living city for Hong Kong, looking ahead to the development blueprint for the Northern Metropolis and New Development Areas.

Easy Asset Management with Radio Frequency Identification Technology
2026-08-06
The daily operation of public facilities and venues involve numerous pieces of equipment. Manual inventory checks are not only time-consuming and error-prone, but also make it difficult for staff to track the equipment in real time. To address these issues, the EMSD introduced a Radio Frequency Identification (RFID) asset management system for the Hong Kong Cultural Centre and the Yau Ma Tei Theatre under the Leisure and Cultural Services Department, saving the time for and improving the accuracy of inventory checks.
The system reads RFID tags attached to equipment and accessories via on-site RFID readers and instantly uploads the data to an online one-stop management platform for asset monitoring. Taking the two venues mentioned above as examples, the system can easily complete inventory checks on hundreds of items at each venue, including lighting fixtures, music stands and drapes. Clients can also access the complete information of each equipment item, such as quantity, storage location, model specifications and maintenance records, through the online platform. Movements of equipment in or out of storage rooms are logged by the system immediately, effectively preventing equipment loss due to unauthorised movements.

Lazy Pack Series: Best Practices for Operation and Maintenance
2026-06-29
To enhance promotional efforts and accelerate the elevation of industry standards, the Electrical and Mechanical Services Department (EMSD) has been successively launching the Lazy Pack series based on Best Practices for Operation and Maintenance Service Manual and Guidelines. Following the edition on "Heating, Ventilation, and Air Conditioning (HVAC) Installations", this issue focuses on "Electrical Installations", distilling the relevant content into three practical recommendations to help you easily grasp the core essentials for safe, reliable, and efficient operation of electrical installations:
• Computerised Asset Management System
• Establish Remote Monitoring Systems
• Develop Emergency Action Plans and Drills
In the future, key points regarding “Fire Service Installations” will also be sequentially condensed into highly illustrated Lazy Packs.
