Watch a 40-meter illuminated dragon take shape — from CAD drawings on a narrow Adelaide bridge to factory prefabrication in Zigong, container shipping, and a four-day on-site assembly.
This behind-the-scenes video traces the full journey of a 40-meter illuminated dragon lantern built for OzAsia Festival in Adelaide. The project began with a site survey on a narrow riverbank bridge and ended with a fully lit dragon spanning the water four days later.
The video is structured around three stages: design and engineering, factory prefabrication in Zigong, and international delivery and on-site assembly. Each stage is shown with actual footage — drone surveys, CAD drawings, steel frame welding, silk pasting, container packing, and bridge installation. It is designed for event planners, venue operators, and festival organizers who need to understand how large-scale custom light art is engineered, delivered, and installed across continents.
The project was delivered for the 15th anniversary of OzAsia Festival, commissioned by the Hong Kong Sydney Economic and Trade Office. According to festival organizers and Hong Kong Government Information Services data, the Moon Lantern Trail attracted 42,000 visitors over four days, with the dragon as its centerpiece and total festival attendance exceeding 106,000.
Opening text introduces the project's core constraints: a 40-meter outdoor installation, a four-day assembly window, and a fixed festival date that could not move. These conditions shaped every engineering decision that follows.
Drone footage captures the bridge and surrounding riverbank. Dimensional measurements and 3D spatial data are collected on-site, then translated into CAD drawings. The drawings show how the 40-meter form was split into modules — each sized to fit both the site's spatial limits and standard shipping container dimensions. A subtitle reads: "Every module was engineered to fit the site exactly."
The camera moves into the workshop. Artisans weld the steel frame, stretch and paste silk panels, and hand-paint scale details across the dragon's body. Traditional Zigong craft techniques are integrated with a modern production workflow: floral scale patterns are applied piece by piece, and modules are assembled and checked as they move through the line.
Close-ups of the dragon head and floral scale detailing. Internal LED lighting is tested on the assembled modules, and a full pre-shipment verification is completed before disassembly and packing. This testing step is what prevents on-site rework once the pieces reach Adelaide.
A crane lifts dragon modules onto the bridge. The modules are positioned and connected by a small technical team working in daylight. No heavy equipment beyond the crane is required on-site, and the full dragon is assembled in four days.
The fully lit dragon spans the bridge, its reflection doubling in the river below. Visitors gather along the riverbank. Wide shots show the dragon in context with the surrounding festival lighting and the crowd.

It shifts the labor-intensive work from the event site to a controlled factory, and compresses on-site work into a predictable window. Traditional on-site fabrication would require flying a large artisan team overseas for weeks — travel, accommodation, and per diem costs dominating the budget, with an unpredictable schedule.
Modular prefabrication reverses this. All production happens in Zigong, where workflows are standardized and quality is verified before shipping. Only a small technical team travels for assembly. For the OzAsia project, that meant a four-day installation window with no heavy equipment beyond a crane, and no extended on-site labor.
The CAD design phase is what makes this possible. Site dimensions are captured precisely through drone survey and manual measurement, then the structure is split into modules that fit both the site's spatial constraints and container dimensions. Every module is pre-tested for fit before leaving the factory — which is why the bridge installation completed with zero delays and zero defects.

Q: How does modular prefabrication reduce costs compared to on-site fabrication?
A: Traditional on-site methods require flying a large team of artisans overseas for weeks, with travel, accommodation, and per diem costs dominating the budget. Modular prefabrication shifts all production to the factory, where controlled conditions and efficient workflows reduce labor hours. Only a small technical team travels for on-site assembly — typically completing installation in days rather than weeks.
Q: What if the installation site has space constraints, like a narrow bridge?
A: The CAD design phase captures precise site dimensions through drone survey and manual measurement. The structure is then split into modules that fit both the site's spatial constraints and standard shipping container dimensions. Every module is pre-tested for fit before leaving the factory.
Q: Can this approach work for installations in other countries?
A: Yes. LanternsArt has delivered projects across more than 80 countries using the same modular prefabrication and container shipping model. Each project begins with a site survey to capture local constraints — cultural, spatial, and logistical — before design begins.
