HKU's world's first remote monitoring program for quality of assembled composite components reduces border crossing inspection manpower

The University of Hong Kong's Wong Chuk Hang Student Dormitory uses MiC (Assembly Synthesis) technology, where components are produced in factories in Guangdong Province.

The research team of the School of Architecture of the University of Hong Kong said that during the COVID-19 epidemic, they developed the world's first applications, including the "Electronic Quality Inspection 2.0 System" that can monitor the production of components from the mainland to their delivery to Hong Kong, and the mobile application platform "Easy Inspection Da". ".

They pointed out that the relevant technology can monitor the whole process of manufacturing and transportation to Hong Kong, which can help reduce the manpower of border crossing inspection and ensure the quality of units.

According to the team, the Wong Chuk Hang Student Dormitory provides a total of 1,224 dormitory spaces, involving 952 components. At present, the factory has completed the production of more than 300 units and is expected to be completed in the second quarter of 2023.

The technology will also be applied to the redevelopment of the West Garden of the University of Hong Kong.

The University of Hong Kong opened a demonstration unit of the new student dormitory today (5th), involving 5 components, including halls, bedrooms and toilets.

The research team of the School of Architecture of the University of Hong Kong said that in order to ensure quality standards, before the epidemic, the industry often sent personnel to cross the border to the factory to test materials, which involved a lot of manpower and paperwork.

However, during the epidemic, due to border restrictions, it was difficult for Hong Kong to send personnel to mainland factories for verification.

Tan Jingliang, director of the Property Office of the University of Hong Kong, said that before the relevant new technology, the industry may have to send 10 to 20 people to conduct on-site inspections, but now the manpower can be greatly reduced, which will help save costs. 300,000 yuan.

Temperature and humidity are known during transportation to help ensure quality

The research team pointed out that "Easy Checkout" is an application (App) that is open to all stakeholders to participate.

The contractor must first establish a task list for the project, and different participants such as structural engineers, authorized persons, etc. can register on the platform.

When a certain construction is completed, the contractor can take a checklist to test item by item, and use the test results and photos to record relevant data.

Tan Jingliang said that "Easy Inspection" can help monitor the details of the component manufacturing process. From delivery to transportation, you can instantly know the location, temperature, and moisture of the module through "Easy Inspection". It will not wait for "receiving". just got it.

Multiple steps to prevent "counterfeiting"

Lyu Weisheng, Associate Dean (Research) of the School of Architecture and Professor of the Department of Real Estate and Architecture at HKU, said that each component has a "birth certificate", and you can check the relevant quality certificate. In order to prevent "counterfeiting", the short videos and photos in the system must be uploaded in real time. , and the fingerprint is used for authentication, so even if there is a problem, the responsibility of each process leader can be traced, and the signed record will be stored in the blockchain network to ensure that it cannot be tampered with.

Architectural Services Department introduced aerial cameras to inspect the three houses and other historic sites, so it was not necessary to build sheds and save one-third of the time Feeling uneasy about the building: In the mid-to-long term, there will be a supply of 1,680 beds in Shenjian Student Dormitory, Dakang Road, Kowloon Tong, Kowloon Tong.
