The Sifangcheng Project is located in the Qiantan area of Sanlin Town, Pudong New Area, covering a total land area of 62,019 m² and a total floor area of approximately 410,396 m², with mixed-use functions for office and commercial purposes. The above‑ground portion comprises 11 separate buildings, interconnected by steel‑structure skybridges; the total above‑ground floor area is about 266,870 m², with the tallest building reaching a height of 52.5 m and rising 11 stories above ground. The underground components are linked via subterranean passageways connecting basements beneath four distinct plots. Two of these plots feature three‑level basements, supported by a retaining system comprising slurry walls, triple‑axis trench wall reinforcement, a TRD cutoff wall, and three concrete support struts. The remaining two plots have two‑level basements, utilizing bored piles, a TRD cutoff wall, and two concrete support struts. The underground passageways interconnect the first, second, and third basement levels of each plot, with a combined total underground floor area of approximately 143,526 m². The first basement level accommodates the staff cafeteria, parking, and mechanical/electrical rooms, while the second and third basement levels house parking and equipment spaces. Pedestrian overpasses on the east and west sides of the site provide connectivity to adjacent parcels. Our company is responsible for the project’s pile foundation and excavation shoring works.
Shanghai Lingang Ice and Snow Star is located in Nanhui New City, Shanghai’s New Area. The project employs two types of pile foundations: precast pipe piles and bored cast-in-place piles. In the basement’s general areas, the bottom slab elevation is –7.80 m, with a slab thickness of 700 mm and a leveling layer thickness of 150 mm. In the southeast corner—where the boutique hotel is situated—and in the northeast corner—within the northern resort‑hotel zone—the typical excavation depth is 6.45 m. In certain localized areas of the northwest corner, the typical excavation depth is 7.75 m. Sump pits are 1.50 m deep, elevator shafts are 1.50 m deep, and elevator fire‑fighting sump pits are 3.00 m deep. For the basement area of this excavation, the retaining structure consists of bored cast-in-place piles combined with a single‑row triple‑axis cement‑soil mixing pile cutoff wall, with an internal reinforced concrete support system. The cutoff wall is constructed using ∅850@600 triple‑axis cement‑soil mixing piles. Within the excavation, reinforcement is achieved through 700@500 double‑axis mixing piles supplemented by compaction grouting.
