Project Overview

Located in Sanya, Hainan Province, China, this large-scale development covers a total building area of approximately 121,984 square meters. The project consists of a 15-story hotel building, a 14-story commercial building, and three basement levels, with some areas extending to only two basement levels.

The overall development adopts a reinforced concrete frame-shear wall structural system, combining the advantages of reinforced concrete construction and steel structural components to meet the requirements of a multi-story commercial and hospitality complex.

Within this project, our company undertook the specialized steel-concrete structural subcontracting work for the main hotel building. The scope involved approximately 3,000 tons of steel structure, covering several important structural components and construction processes.

This project demonstrates our experience in handling large-scale steel structure works integrated with reinforced concrete building systems.

Steel-Concrete Structural Scope

The hotel building required the coordinated installation of multiple steel components and their integration with the reinforced concrete structure. Our subcontracting scope covered the fabrication-related and on-site construction activities associated with the following key elements:

1. Box Columns

Box columns formed an important part of the steel structural system. Their dimensional accuracy, connection details, and installation positioning were essential to ensuring proper integration with the overall building structure. Careful coordination was required during installation to meet the project drawings and construction specifications.

2. H-Beams

H-beams were used as major horizontal structural members. Their installation involved positioning, alignment, connection, and coordination with the supporting columns and other structural components. Accurate installation was important for maintaining the designed structural geometry.

3. Metal Floor Decking

Metal floor decking was included in the steel-concrete floor construction system. It served as permanent formwork during concrete placement and formed part of the composite floor assembly according to the structural design. Installation quality and coordination with reinforcement and concrete work were important considerations.

4. Shear Studs

Shear studs were installed to provide the required connection between steel members and concrete elements in the composite structural system. Their positioning and installation quality were important to achieving the designed composite action between the steel and concrete components.

5. Steel-Concrete Connections

Steel-concrete connection details required close coordination between the steel structure and reinforced concrete construction teams. These interfaces involved multiple components and construction procedures, making drawing review, dimensional control, and installation sequence important throughout the work.

Construction Coordination and Technical Requirements

With nearly 3,000 tons of steel structure involved, the hotel building presented substantial requirements for construction organization and technical coordination.

One important consideration was the integration of steel components with the reinforced concrete frame-shear wall system. Box columns, H-beams, floor decking, shear studs, and steel-concrete connection details had to be coordinated with the relevant concrete construction activities.

The construction process therefore required careful attention to structural drawings, component positioning, connection details, and the sequence of installation. Coordination among different construction teams was essential to ensure that steel structure activities could be properly integrated into the overall building schedule.

For a high-rise hotel building, dimensional accuracy and installation control are particularly important. Deviations in column positioning, beam elevation, or connection details can affect subsequent construction activities. Consistent technical communication and on-site coordination help address these challenges during implementation.

Steel Structure Expertise for Complex Building Projects

Modern commercial and hospitality developments often combine different structural materials and construction methods to meet architectural, functional, and engineering requirements.

Steel-concrete composite construction can bring together the structural characteristics of steel components and reinforced concrete systems. However, successful implementation depends on more than the supply of steel materials. It requires technical understanding of component connections, construction sequencing, installation accuracy, and coordination across multiple trades.

Through our participation in this Sanya hotel project, our company undertook a substantial steel-concrete structural subcontracting scope within a large commercial development. The approximately 3,000-ton steel structure works covered key structural components and several important stages of construction.

Conclusion

The Sanya hotel project, with a total development area of 121,984 m², represents a large-scale building project involving a 15-story hotel, a 14-story commercial building, and multiple basement levels.

Our company's responsibility for the main hotel building's steel-concrete structural subcontracting work included box columns, H-beams, metal floor decking, shear studs, and steel-concrete connections, involving approximately 3,000 tons of steel structure.

This project reflects our capabilities in steel structure construction and the coordination of steel components with reinforced concrete building systems. We continue to provide steel structure construction services for commercial buildings, hotels, industrial facilities, and other complex engineering projects.
