Kai Tak Radome – Hong Kong

McConaghy Composite Solutions were contracted by the consulting firm BMT Asia Pacific, to provide composite expertise and turn-key supply of the nearly 500m² composite Radome, which was mated with a support platform and harbour control radar system. The Radome, the largest composite structure in Hong Kong towers 30 metres above the Kai Tak Terminal.

McConaghy provided:

• Engineering design of structure to stringent typhoon conditions
• Design and fabrication of twin molds
• Lamination of twin GRP “egg shell” structures
• Integration and mating of steel support structure
• Form and finishing of final egg structure
• Provision of access ladders, lightning conductors and aviation lights

Extensive R&D was undertaken into radio frequencies and permeability through various composite material options by BMT & McConaghy. The radome was resin infused using a fire rated system, it was constructed in two hemispheres and joined around its equator.

The project also involved other challenges that McConaghy needed to make sure were met. It was important that the radome was aesthetically pleasing but was a structure of significant strength, and light enough to permit a single lift installation.

“We were well supported by McConaghy’s project management team in developing and pursuing a build strategy that met the key challenges within the time constraints of the terminal’s construction. We found the team eager to embrace the challenges of this unusual project and the final outcome, now installed on site, looks set to be a new landmark on Hong Kong’s harbour. We would not hesitate to recommend McConaghy for projects of a similar nature, and indeed look forward to working with them ourselves should we identify future opportunities requiring such expertise.” – Richard D Colwill, BMT Asia Pacific Managing Director
