Co-creating a Smart City
The Electrical and Mechanical Services Department (EMSD) is committed to seeking continuous improvement. We promote E&M digitisation and establish an excellent work team, striving to provide electrical and mechanical (E&M) engineering services to our client departments with innovation and technology (I&T). We proactively play the role of a “facilitator” and a “promoter” to drive the application of I&T with a view to building Hong Kong into a smart city.
First, digitised systems and I&T training facilities have been applied in our newly established Customer Service Centre (CSC) and Interactive Learning Centre (ILC) to enhance maintenance efficiency and the technical capability of trainees. We have also set up the E&M InnoZone and E&M InnoPortal to collaborate with universities and start-ups in I&T and provide testing grounds for their projects with technical support. Furthermore, advanced systems and equipment in various areas have been introduced and tested, including installation of the Cave Automatic Virtual Environment (CAVE) system in the headquarters building and the implementation of several pilot projects, e.g. the facial recognition system and puzzle parking system, etc. We hope that we can cater to the development needs of our clients in serving the public through various initiatives and co-create Hong Kong into a smart city with our clients and the E&M trade.
The EMSD actively supports the Government’s policy of building Hong Kong into a smart city in recent years. To this end, we proactively promote digitisation of E&M facilities. Mr. Alfred Sit, Director of Electrical and Mechanical Services, said at a media gathering held on 4 December 2018 that the new CSC established in the EMSD Headquarters Building is equipped with the advanced remote monitoring system, which can monitor around 1 800 sets of traffic light and the E&M facilities of around 200 pedestrian tunnels across the territory in real time, improving the system availability and reliability, as well as connection with customers.
In addition, we have been investing resources in the development of digitised asset management systems, such as the Building Information Modelling - Asset Management (BIM-AM) system, which enhances efficient maintenance of E&M facilities. Besides, the EMSD has been carrying out the installation of digitised equipment for the E&M facilities at more than 400 government buildings with annual electricity consumption exceeding 500,000 kWh to enhance operational efficiency and environmental performance of the buildings.
Furthermore, to enhance the management of engineering projects and assist clients in reviewing different design proposals effectively, we have adopted the Building Information Modelling and CAVE technology to create a virtual environment in advance at the early planning stage of construction and improvement works. Clients can personally experience different design proposals in a virtual reality (VR) setting with ratio close to 1:1. This not only saves time and resources for producing an actual mock up, but also enables prompt assessment of and revision to the design, which can effectively improve work efficiency.
Excellent Work Team
To tie in with the new development trend, the EMSD has set up in our headquarters building an ILC, which not only enables training in a VR setting to enhance trainees’ maintenance skills, but is also expected to attract young people to join the trade through an interactive training mode with innovative technology. The virtual environment allows trainees to further familiarise themselves with operation and maintenance procedures under a diversified mode of learning without being on-site, particularly in places under control (such as operating theatres) or dangerous locations (such as lift shafts), thereby providing clients with better and more precise services.
We combined the BIM-AM system with CAVE facilities in September 2018, and applied them to simulate the environment of the Hong Kong Children's Hospital and Tin Shui Wai Hospital, to further strengthen training of the EMSD’s maintenance staff.
As an I&T “facilitator” and “promoter”, the EMSD takes the initiatives to bring in advanced technologies, and encourages the industry to collaborate and work out innovative solutions. Our E&M InnoPortal is dedicated to experience and technology exchange, and matching suitable I&T projects for government departments. Since March this year, we have received a total of more than 100 “I&T Wish Lists” and over 70 innovative solutions, covering such areas as Internet of Things, automation technology and artificial intelligence. At present, we have been helping to test more than 40 projects in different government venues and facilities.
One of our I&T projects is to improve the efficiency of crowd management for client departments. We have taken the lead to implement a pilot project in our headquarters building by installing intelligent facial recognition devices at certain staff entry and exit gates to test the effectiveness of the application of facial recognition technology in access management of the building, as well as the accuracy of the algorithm developed by the supplier. Video content analytics technology is becoming increasingly mature, with a series of functions for smart analysis of videos, facial recognition being one of them. The facial recognition system automatically compares the captured images with records in the database, which can effectively identify the identity of registered persons to enhance security. We will test other features of the video content analytics technology one by one, such as statistics on the number of people, detection of wrong direction and monitoring of queue length, and will share the results of the analysis with clients to promote the application of the technology to different client departments.
Another I&T project is to enhance the efficiency of road utilisation. We organised a delegation with client departments earlier to the Guangdong-Hong Kong-Macao Greater Bay Area to study the latest I&T projects there, among which the three-storey Puzzle Parking System could increase the parking capacity of parking locations, we therefore took the initiative to bring in this parking system and made our headquarters building a testing ground for the pilot project. The system installation is expected to be completed in mid-2019, and the testing results will be provided to the Transport Department for reference later. In addition, to prevent traffic incidents and strengthen road safety, we have co-operated with a start-up company for trial run of the Safematics Smart Safety System (4S) Solution. Traffic conditions are monitored through sensors and video cameras installed in the front of vehicles. By collecting the big data of driving records, the system can analyse drivers’ driving behaviour and identify traffic blackspots to achieve the vision of “Zero Accidents on the Road”. We will promote the application of such technology to other client departments.
