III. Hainan Coastal Exclusive GRC Dry-Hanging Anti-Corrosion Technology Standard

In response to the high salt spray, strong ultraviolet radiation, and high temperature and humidity marine climate of Haikou, Hainan, this project has upgraded all materials and installation systems with specialized anti-corrosion measures. All construction details are strictly written into the construction contract, making it fully suitable for the long-term outdoor use needs of coastal cultural and tourism buildings.

1. GRC component base material standards: The thickness of linear and flat components is uniformly ≥15mm, and the thickness is uniform. Irregularly shaped components are integrally molded, and the mold opening accuracy is controlled at ±2mm to prevent surface deformation and cracking. The base material is added with alkali-resistant glass fiber and impermeable modifier to improve its resistance to salt spray corrosion.

2. Dry-hanging keel anti-corrosion system: All supporting steel frames are hot-dip galvanized to prevent corrosion from sea breeze chloride ions;

3. Stainless steel corrosion-resistant connectors:

The embedded base layer uses S316 stainless steel sleeves and stainless steel embedded parts;

M12 chemical anchors were used for wall anchoring and embedded in the main structure.

M10 stainless steel bolts are used to connect the components to the keel , with no carbon steel fittings, to prevent rust from polluting the facade.

4. Scope of all-inclusive construction: The contract unit price includes all processes such as mold customization, component production, finished product transportation, and on-site manual installation, with no hidden additional items;

5. Acceptance criteria: All materials and construction techniques comply with the current national and Hainan local housing and construction department standards. The final acceptance shall be based on both the construction drawings and the technical terms of the contract.

IV. Segmented and Interleaved Project Schedule Management Plan

The Dutch section involves numerous individual buildings and cross-disciplinary work across civil engineering, mechanical and electrical engineering, and landscaping. The project team adopted a staggered construction schedule, with phased handovers and overlapping work phases. The contract clearly states that the construction period already includes statutory holidays, the Hainan rainy season, typhoons, and other adverse weather conditions and the impact of overlapping work, thus requiring no additional extensions.

The following buildings will be constructed first: Cheese House, Block C, Stadium, and Windmill, and will be completed in the first three months of the year.

The second phase of simultaneous construction includes the church, blocks A, B, and D, and the open-air theater, with construction commencing in April.

A dedicated safety and civilized construction management team is on-site, and special expenses are charged separately for safety protection, temporary facilities, and nighttime construction during the rainy season to ensure the safety and compliance of outdoor high-altitude operations in the coastal area.

Frequently Asked Questions

Q1: Why must S316 stainless steel embedded parts be used for the exterior wall GRC of cultural tourism projects along the Hainan coast?

A1: Hainan has a high-salt-fog coastal climate. The chloride ions from the sea breeze will quickly corrode ordinary carbon steel and 201 stainless steel. S316 stainless steel has excellent resistance to chloride ion corrosion. Combined with hot-dip galvanized keel and stainless steel connecting bolts, the whole dry-hanging system can guarantee no rust or wall rust stains for more than 20 years. It meets the anti-corrosion design requirements of JGJ/T 423-2018 for coastal GRC projects and is also the mandatory material standard in the contract of this Changying Netherlands project.

Q2: What costs are included in the comprehensive GRC unit price for this project, and are there any additional charges later?

A2: The comprehensive unit price in this project list fully includes mold making, GRC component production, finished product transportation, and on-site installation labor. Safety and civility measures, rainy season night construction and other measures fees will be adjusted accordingly based on the actual project volume. The contract clearly states that there are no hidden additional items. All cost and fee rules are written in black and white in the construction contract, and the settlement is traceable.

Q3: How to resolve the scheduling conflicts when multiple buildings are working simultaneously in a cultural and tourism complex using GRC construction?

A3: Drawing on the experience of the Changchun Film Studio's Holland project, a phased and staggered entry and handover construction mode was adopted. The construction work areas for each building were divided in advance, and the civil engineering, electromechanical, and GRC construction teams were arranged in staggered shifts. The rainy season, holidays, and high-altitude cross-operation buffer time were directly included in the construction period calculation to avoid claims for construction delays.

Q4: Can GRC components with a thickness of less than 15mm be used for outdoor exterior walls in Hainan?

A4: Not recommended. Coastal outdoor environments are subject to prolonged sun and rain, making thin GRC prone to cracking, weathering, and water seepage. Changying's Dutch contracts mandate that flat and linear components be at least 15mm thick. Thicker substrates improve the components' crack resistance, water resistance, and weather resistance, making them suitable for Hainan's harsh outdoor environment.

Q5: For large-scale cultural tourism GRC projects worth tens of millions of yuan, what qualifications and case studies should be considered when selecting a general contractor?

A5: Prioritize companies with Class II qualifications for building decoration construction, GRCA international GRC association certification, and their own standardized production base; focus on verifying similar large-scale cultural tourism theme park implementation cases, complete construction contracts, and special anti-corrosion construction technical solutions to avoid small subcontractors without experience in large-scale projects from having problems with model reproduction and anti-corrosion.
