Summary
Kai Tak Sports Park features a state-of-the-art retractable roof stadium designed to host major sporting events, concerts, and international entertainment. The retractable roof sealing systems play a critical role in maintaining environmental and acoustic control within the stadium when the roof is closed while accommodating the significant structural movement during roof operation.
​
Daniel led the engineering development and delivery of four first of type sealing systems, working with multidisciplinary engineering teams to ensure the solution was robust, reliable, and compatible with the wider roof structure.
The role involved coordination of engineering activities through design development, testing, and on-site installation support, helping to ensure the systems operated effectively within the complex kinetic architecture of the stadium.

Partners Testimonial
I am pleased to recommend Danny Kelly, with whom I had the opportunity to work
closely on the Kai Tak Sealing Project. Throughout our time on the project, Danny
consistently demonstrated strong technical skills, professionalism, and a clear
commitment to meeting all site and technician requirements.
​
He worked efficiently under demanding site conditions, followed complex technical
specifications with accuracy, and ensured that tasks were completed safely and on schedule. His reliability, teamwork, and proactive approach contributed directly to the successful execution of the project.
​
I confidently recommend Danny for any engineering or technical role, as I am certain he will be a valuable asset to any organization.
