According to the Voice of China News and Newspapers, on March 31, the first phase of the Jinan Supercomputer Center completed the construction of all the main structures and facades.
Jinan Supercomputer Center Science and Technology Park Project is one of the petascale national supercomputing centers approved by the Ministry of Science and Technology. The total construction area is about 617,000 square meters. After the project is completed, it will
serve the world-class E-class supercomputer . Millions of mathematical calculations can be made in seconds.
Zhu Chao, the person in charge of the project of the 8th Bureau of China Construction Eight: The project team fully guarantees the input of manpower, materials and equipment. It takes only 108 days from the foundation treatment to the main structure and the façade decoration construction.

78 days! Extreme speed challenges the world's "strongest brain"
The high positioning of the project brings "limit speed": from the foundation treatment to the main structure and the façade decoration construction is only 108 days, the main building has more than 13,000 pieces of steel structural members, the construction period is only 40 days, the average steel structure per layer The installation time is only 2.5 days, the total steel structure is about 26,000 tons, and an average of 700 tons per day is needed...
According to Qilu.com, in the face of extreme speed, the project department optimizes the construction and deployment, and the work plan is accurate to every day, so that it can be “pre-planned”. Before the start of construction, according to the needs of specific construction stages, special welders, shelf workers, etc. are reserved. In order to prevent the logistics lag that may occur during the Spring Festival, the steel structure, stone, profiles and other materials were reserved in advance, and an emergency logistics company was prepared.
The super-calculation center main building has a single floor area of 28,000 square meters and is a steel frame structure with buckling constraint support. The project department optimized the beam-column joints to the steel bull-leg joints. The installation time of one steel beam was reduced from 60 minutes to 15 minutes, and the work efficiency was improved by 75%, which was safe and fast. At the same time, the improvement of the lifting tooling, the use of a hoist can be installed 3-4 steel beam string crane technology, work efficiency increased by 200%.
The project insists on “all-weather construction, spring festival does not fight”. During the peak construction period, 60 sets of hoisting machinery and equipment, more than 1,500 laborers and 24 hours of uninterrupted construction; 3,500 tons of steel bar installation and 35,000 square concrete pouring; 15 days Completed 34000 square meters of 6000KN.m strong foundation replacement treatment and test; completed 26,000 tons of steel structure hoisting work in 35 days... The
project only took 78 days to realize the super-calculation center main building steel structure capping, refreshing the domestic single steel Structure installation speed.
Assembled curtain wall "Building blocks"
The main building of Jinan Super-calculation Center, you can see the outer wall of the ring building, neatly lining a row of imitation stone cube curtain wall, highlighting the beauty of "rigorous" under the sun.
Due to the arc-shaped shape of the exterior wall of the building and the tight construction period, the project team has deliberately designed and optimized the design, creatively designed the component curtain wall into a unit body, and realized the assembly construction of the curtain wall. This kind of construction is similar to “building blocks”. The curtain wall unit is processed off-site. Only the hoisting work is carried out in the project site. Nearly 100,000 square meters of building facade façade installation is completed in only 20 days.
This geometric unit curtain wall is processed by the curtain wall processing factory of the China Construction Eighth Bureau Second Company Decoration Company, and the interior is a steel frame structure. Before the production, the project team used BIM software to build a fine 3D model of the curtain wall structure, pre-assembled, and produced accurate steel frame processing molds to ensure the accuracy and reliability of the processing.
The project team also adopted the measuring line artifact -
BIM line-up robot , which achieved efficient and accurate positioning of the line, ensuring the installation accuracy of each unit body curtain wall, achieving beautiful and energy-saving effects, highlighting high quality and high Level architectural style.
In 108 days, a 110,000-square-meter cylindrical super-computing center main building was built with first-class efficiency and first-class quality. This amazing construction process is the result of team operations and the result of concerted efforts by all parties. The Licheng District Government of Jinan formed the construction headquarters on the day and night of the project construction task, and the deputy head of the district served as the chief commander. The district construction committee, the examination and approval bureau, the audit bureau, the district quality supervision station, and the Licheng Holding Group leaders were stationed at the scene to open a green channel. Timely solve problems related to formalities approval and financial audits that occurred during the construction of the project.
