Qingdao Cardiovascular Hospital Phase III Project - Qingdao Yoshine

Our company is the contractor for the Phase III Renovation and Expansion Project of Qingdao Cardiovascular Hospital.

I. Project Overview:

Project Profile: The Phase III Renovation and Expansion Project of Qingdao Cardiovascular Hospital has a total construction area of 57,700 m², comprising 32,500 m² above ground and 25,200 m² below ground. The project scope includes one Rehabilitation Medicine Building (15 stories above ground), partial connecting corridors, a wartime emergency hospital, and underground parking facilities (4 basement levels). The building height is approximately 67.5 meters.

The project involves the construction of a 12-story Rehabilitation Hospital Building (12 stories above ground, 3 basement levels, total floor area of 52,150 m², plot ratio of 3.75) on a 5.85-acre site east of the current hospital location. The building will cover a footprint of 3,900 m², with a green space ratio of 21% after deductions. The Rehabilitation Hospital Building is planned to accommodate 300 patient beds.

The new building will occupy 126 above-ground parking spaces originally belonging to the existing hospital. In accordance with Qingdao municipal regulations, the new Rehabilitation Hospital Building must provide 517 parking spaces, resulting in a total requirement of 643 parking spaces. A 5-story mechanized parking facility will be constructed to meet this demand.

Structural System:

The project adopts a steel-concrete composite structural system, integrating steel frames with reinforced concrete (rebar) components through scientific structural design to form an efficient and working system. The perimeter frame utilizes a full steel frame system, with main beams and columns made of Q355B steel, providing primary lateral resistance and vertical load-bearing capacity. The internal secondary structure employs a cast-in-place rebar concrete system, including ring beams at mezzanine levels, lintels, structural columns, and floor slabs, collectively forming a complete spatial and load-bearing system.

This structural approach leverages the high strength and ductility of steel alongside the durability and fire resistance of concrete, achieving an optimal balance between structural safety and economic efficiency. The steel component facilitates long-span capabilities and rapid construction, while the rebar concrete element provides essential stiffness and mass damping. Together, they ensure the building meets functional and seismic performance requirements.

Through standardized construction processes and comprehensive quality control, the project will realize the design intent and deliver a high-quality steel-rebar concrete structure that complies with regulations and fulfills functional requirements.
