Project Overview
As a key benchmark project in the core business district of Shijiazhuang High-Speed Rail New City, the Shijiazhuang High-Speed Rail No.17 Land Project is a high-end commercial office complex integrating business offices, commercial supporting and public services. It is constructed by Shijiazhuang Construction Engineering Co., Ltd. with a total investment of about 939.6 million yuan, a total construction area of 156,517 ㎡ and a maximum building height of 148.5 meters. The project consists of 3 main buildings: Building 1 (30-story office building), Building 2 (4-story commercial building) and Building 3 (21-story office building with 2-story commercial podium). It is positioned to gather high-quality enterprises, drive the economic development of the high-speed rail new city and build a new urban landmark of Shijiazhuang.
Steel Structure Core Advantages
Steel structure is the core load-bearing system of the project, which fully exerts its technical characteristics and comprehensively optimizes the project quality, construction efficiency, safety performance and economic benefits. The core advantages are as follows:

English Description |
|
Efficient Construction |
Core steel components (steel columns, beams, trusses) are prefabricated with millimeter-level precision in the factory. On-site construction only requires hoisting and assembly, reducing on-site wet work by 80%. The construction period is shortened by 30%-50% compared with traditional concrete structures, effectively ensuring on-schedule completion and early operation. |
|
️ Safe & Stable |
Adopting high-strength steel (Q235B, Q355B) with excellent toughness and uniform mechanical properties. It has excellent seismic resistance (8-9 grade) and wind resistance (10-12 grade), with inter-story drift limit ≤ H/500 (H is building height). Hot-dip galvanizing + anti-corrosion coating treatment ensures 50-100 years of service life with low maintenance costs. |
|
Green & Energy-Saving |
Lightweight steel structure (only 1/3-1/2 of concrete structure's self-weight) reduces foundation load, enabling more economical foundation design. Factory prefabrication minimizes on-site waste and noise, meeting green building standards and realizing low-carbon construction throughout the life cycle. |
|
Flexible Space |
Steel structure has strong adaptability to space layout, which can easily meet the flexible design requirements of large-span commercial spaces, open office areas and multi-functional supporting areas. It supports flexible adjustment of internal functions to adapt to long-term operational needs. |
Project Highlights
1. Intelligent Construction Innovation：Introduces lightweight "air construction factory" (integrated support, formwork, protection systems), transforming traditional high-altitude scattered operations into factory assembly line construction, improving construction safety and precision by 30%.
2. Regional Economic Driving：Located in the core area of Shijiazhuang High-Speed Rail New City, it connects the regional transportation hub and industrial agglomeration effect, becoming an important engine for the economic development of the high-speed rail economic circle.
3. Standardized Quality Control：Complies with national steel structure design standards (GB 50017-2017), with full-process traceability of component production, construction and acceptance, ensuring project quality meets international high standards.
Application Value
This project perfectly demonstrates the comprehensive application advantages of steel structure in urban high-end commercial office complexes. It not only provides a high-quality reference case for similar projects in China and abroad, but also verifies the feasibility of steel structure in large-scale, high-rise and green urban construction projects, laying a solid foundation for the popularization and application of steel structure in international markets.
