Arup partners with YJK to launch AI Designer in Hong Kong to advance AI-enabled structural engineering

Jointly developed by Arup and YJK, the initial AI Designer modules combine Arup’s global structural engineering experience and advanced computational design expertise with YJK’s integrated software capabilities in analysis, code-compliant design and drawing production. The first phase of the platform focuses on two core applications: Structural design optimisation, including reinforced concrete and steel structures, and Piled foundation layout and design optimisation.

The platform helps engineers evaluate design options more effectively, enabling faster decision-making, improved project outcomes and smarter project delivery, while representing a transformational step forward in modernising engineering workflows.

Key features of AI Designer

• YJK's structural design software (Hong Kong Code Edition) has been officially recognised by the Hong Kong Buildings Department, while its structural, BIM and construction software suite has been certified under Hong Kong's Construction Innovation and Technology Fund (CITF).
• In controlled benchmarking using the same model, loads and code, and with engineer review retained, AI Designer's algorithmic optimisation reduced design iteration time by approximately 82% (from 2.5 days to 0.5 days) and decreased over-limit components by around 88% (from 64 to 6).
• Through AI Designer's optimisation, material usage could be reduced by around 10–20%, contributing to lower embodied carbon.

The partnership underscores Hong Kong's ambitions to accelerate the adoption of digital technologies across the construction sector. By enhancing productivity and streamlining engineering processes, AI Designer will bring more efficient project delivery while strengthening the city's position as a centre for technology-led innovation in the built environment.

Theresa Yeung, Managing Principal, East Asia of Arup, said: “We are delighted to collaborate with YJK on the launch of the first AI Designer module. By combining Arup's deep structural engineering and computational design expertise with YJK's advanced software capabilities, we are empowering engineers with powerful tools that improve workflows, accelerate design exploration and unlock new opportunities for innovation.

As projects become increasingly complex, AI Designer will enable us to assess a broader range of solutions more efficiently while maintaining the highest standards of technical excellence. This reflects our commitment to applying emerging technologies to deliver better outcomes for our clients, communities and the built environment."

Chen Dailin, Chairman of Beijing YJK, said: "We are thrilled to partner with Arup, an industry heavyweight with deep expertise in computational design. By combining YJK's software capabilities with Arup's optimisation algorithms, AI Designer will deliver real impact by enhancing design quality, broadening the application of artificial intelligence in engineering, and supporting the development of a smarter, more efficient and resilient built environment."

The launch ceremony was attended by representatives from both the public and private sectors, reflecting the growing importance of advanced technologies in driving innovation across Hong Kong's construction and infrastructure industries. Attendees were introduced to AI Designer's capabilities and its vision for the future of AI-enabled engineering and design.
