Modular construction technology is becoming an important tool for addressing Hong Kong’s housing shortage. According to data from the Hong Kong Housing Authority, using Modular Integrated Construction (MiC) technology can reduce construction time by 30% to 50% while cutting site waste by 80%. This technology is particularly suitable for high-density residential projects in Hong Kong.
In recent years, the Hong Kong government has vigorously promoted MiC technology, successfully piloting it in several public housing projects. The recently completed Tseung Kwan O MiC public housing project set a new record for public housing construction speed in Hong Kong, completing a 40-story residential building in just 16 months. The project used factory-pre fabricated modular units, with on-site work limited to assembly, significantly reducing the impact on the surrounding environment.
The smart modular construction system developed by Hong Kong Golkia Company integrates BIM technology and IoT monitoring, achieving end-to-end digital management from design to construction. The system can track the production, transportation, and installation status of each building module in real-time, ensuring controllable project progress and quality. Currently, this technology has been applied in several transitional housing projects in Hong Kong, helping over 2,000 families move into new homes earlier.
Although modular construction has obvious advantages, its promotion in Hong Kong still faces challenges. First is land constraints: modular construction requires sufficient space for storing and assembling prefabricated components, but Hong Kong’s land resources are limited. Second is regulatory lag: current building codes lack clear approval standards for modular construction, increasing project uncertainty.
The industry predicts that with technological advancements and policy improvements, 30% of new residential buildings in Hong Kong will adopt modular construction technology by 2030. This will not only accelerate housing supply but also improve consistency in construction quality, providing citizens with better living environments.
