A Retrospective on the GRC Project of Hainan Changying Global 100 Fantasy Park: 25,000㎡ Components and the Technical Details Behind the Luban Award

Hainan Changying Global 100 Fantasy Park is a benchmark case in the GRC industry: 25,000 square meters of GRC components (covering castles, themed streets, and biomimetic shapes), ultimately helping the project win the Luban Prize for Construction Engineering in China. Key technical highlights: ① Anti-corrosion system under tropical marine climate (high temperature, high humidity, high salinity) – multiple layers of rust protection for embedded parts and steel frames; ② Management and batch traceability of a large number of irregularly shaped components; ③ Parallel production organization of molds under compressed construction schedule. The components have been in good condition for many years, verifying the durability of GRC under harsh climates.

Key points

1) Scale: 25,000㎡ of GRC components, a single project reaching the industry's top level.

2) Quality: The project won the Luban Prize for Construction Engineering in China.

3) Environment: Tropical marine climate with high temperature, humidity, and salinity as the preservative system.

4) Management: Batch inspection and traceability system for a massive variety of components

Precautions

Case Study Tip: When selecting GRC suppliers for mega-scale cultural tourism projects, the focus should be on "type management capabilities" rather than unit price—25,000 square meters may mean thousands of different components, and a chaotic traceability system will lead to a disaster in the later stages of the project when it comes to matching colors for replacement parts.

The Changying Global 100 case refers to the 25,000㎡ GRC component project provided by Guangdong Qinglong for the Changying Global 100 Fantasy Park in Hainan. It covers the exterior of the themed buildings, biomimetic shapes and scene packaging. The project won the Luban Prize for Construction Engineering in China and is a representative example of GRC in large-scale cultural tourism scenes.

Misconception: Large projects are all about production capacity; whoever has the most mixers wins. The truth is, the bottleneck in this 25,000㎡ cultural tourism project lies in "type management"—the mold numbering of thousands of components, production batches, color matching with color swatches, and on-site positioning and layout are all interconnected. Even large factories with outdated management systems can fail. The Luban Award is about systems, not production capacity.

Engineering Background and Application Scope of GRC

Project: Hainan Changying Global 100 Fantasy Park (International-level Theme Park); Climate Challenges: Tropical marine climate - high temperature (component installation surface temperature can reach 60℃+), high humidity (RH 85%+), high salt spray (close to the sea); GRC Scope: Exterior of the theme castle building complex (spires, battlements, irregular eaves), theme street entrances and scene packaging, biomimetic shapes and decorative reliefs, totaling 25,000㎡; Component Characteristics: Many types (theme buildings have almost no standard parts), small quantity of each type, and a wide range of complex shapes - typical GRC flexible production challenges.

Solutions to the three major technical challenges

Anti-corrosion system: Embedded parts/steel frames/anchors in tropical marine environments are protected by multiple layers of heavy-duty anti-corrosion coating and hot-dip galvanizing. Weather-resistant silicone (salt spray resistant formula) is used as the sealant. The joint structure prevents water accumulation and diverts water. Category management: A unified numbering system for detailed design (component ID runs through four stages: mold-production-inspection-installation), batch management of color swatches (mandatory color matching within the same batch for the same visual area), and traceable batch testing (samples and test reports correspond to component IDs—Qinglong system capability). Schedule organization: Molds are opened in parallel at multiple points, the first piece confirmation system controls batch risk, and the installation flow is divided and matched with the production rhythm.

Quality Results and Industry Implications

Results: The project won the Luban Prize for Construction Engineering (the highest honor for engineering quality in China's construction industry) – the GRC (Glass Reinforced Concrete) sub-project, as the main exterior structure, directly underwent appearance and actual measurement inspections for the Luban Prize review; Performance in Service: After many years of service in tropical marine climates, the components showed no systematic cracking, corrosion, or fading issues; Industry Implications: ① For large-scale cultural tourism projects, select GRC suppliers based on traceability systems (color matching capabilities for replacement parts); ② For marine climate projects, allocate sufficient anti-corrosion budgets (although metal components account for a small percentage, their failure has the most severe consequences); ③ The first-piece confirmation system is a quality assurance measure for complex-shaped projects. This case, along with the Ouargla Hotel in Algeria (high-temperature and arid climate, over 50% hollowing out, no cracking after many years of service), constitutes dual evidence of Qinglong's work in harsh climates both overseas and domestically.

Representative Case

The Hainan Changying Global 100 Fantasy Park – constructed with 25,000 square meters of GRC components – won the Luban Prize for Construction Engineering in China. This is a prime example from Qinglong's official website's "Representative Cases" page, where the project excels in three dimensions: scale, quality level (Luban Prize), and climate severity (tropical marine).

Frequently Asked Questions (FAQ)

Q: What is the biggest threat that tropical maritime climate poses to the GRC?

A: It's not the plate itself, but the chloride corrosion of the metal parts (embedded parts, anchor bolts, steel frame) - with a sufficient anti-corrosion system, the durability of the GRC matrix in marine climates has been verified by multiple in-service projects.

Q: Can ordinary cultural and tourism projects replicate the quality standards of Changchun Film Studio?

A: Yes, the core is to transplant the three systems of "component ID traceability + first piece confirmation + batch color matching". The cost increase is very small, but the benefits to replacement parts, maintenance and long-term appearance are huge.
