Xuzhou Economic and Technological Development Zone Big Data Smart Valley Project
Project Composition
Of the four towers delivered by ZM-BESTA, Tower D3 integrates a library, cultural center, youth activity center and trade-union activity center, serving as a landmark public building of the development zone; Towers A2, A3 and D2 are business office buildings for big-data enterprises in the park. The towers rise 12–21 stories with a maximum height of approx. 78 m; podiums are 4 stories. All buildings were designed and constructed as prefabricated steel structures, achieving an overall prefabrication rate above 70%.

Structural System & Materials
As a cluster of prefabricated steel office towers in the 70-meter class, the project applies the complete technical configuration of ZM-BESTA’s multi-story heavy steel building system:
- Vertical structure: rectangular steel tube composite columns (partly concrete-filled) above grade for superior load capacity and seismic performance; steel-reinforced concrete columns and beams in the basement
- Horizontal members: hot-rolled and welded H-section steel beams (个别 composite steel-concrete beams); box-section columns in the podiums
- Floor system: steel-bar truss decking with cast-in-place concrete, eliminating full formwork and shoring and enabling parallel multi-floor construction
- Envelope: ALC precast wall panels combined with glass curtain walls externally, ALC panels internally; delivered fully fitted out
- Industrialization: a fully industrialized chain of design, component manufacturing and on-site assembly with prefabrication rates above 70%, officially recognized as an integrated prefabricated steel demonstration in Jiangsu Province
Track Record & Recognition
- Delivered under an EPC consortium integrating design, procurement and construction (turnkey general contracting under China’s standard GF-2017-0201 contract form)
- Named a Jiangsu Provincial Building Industrialization Integrated Application Demonstration Project in 2020
- Won the Third Prize (Integrated Prefabricated Steel Demonstration category) of the 2023 Jiangsu Building Industrialization Outstanding Achievement Awards
- With complete site photos and structural documentation on file, it serves as ZM-BESTA’s core reference for high-rise prefabricated steel industrial parks
