On February 13, 2022, local time, the new headquarters building of the Ethiopian Commercial Bank, the tallest building in East Africa, undertaken by China Construction Eighth Bureau, a subsidiary of China State Construction, was officially completed. Ethiopian Prime Minister Abiy, Chinese Ambassador to Ethiopia Zhao Zhiyuan and others attended the completion ceremony.

The new headquarters building project of Ethiopian Commercial Bank is located in the business center area of the capital Addis Ababa, with a total construction area of 160,000 square meters and a tower height of 209 meters. The development provides strong momentum and contributes to the promotion of the lasting relationship between China and Ethiopia and the mutual benefit and win-win situation between China and Ethiopia.

In his speech, Abi congratulated the completion of the building, saying that the completion of this beautiful building on the occasion of the 80th anniversary of the establishment of the commercial bank reflects Ethiopia's ambition to promote the modernization of the banking industry. Abe Sano, President of Ethiopian Commercial Bank, said he believed that the completion of the new headquarters building would greatly improve the efficiency of the bank and bring advanced technology to Ethiopia's construction industry.

The structure of the main tower of the project is designed with diamond cut planes. There are 5,208 tower curtain wall panels, each of which has different inclination angles and sizes, giving the building a gorgeous "diamond coat".

The construction difficulty is proportional to the aesthetics of the modeling. The installation of the curtain wall needs to control the accuracy within the millimeter-level error range. The project produces a 3D machining model drawing through BIM modeling, and uses the 3D machining model drawing as a reference to measure the plane machining drawing data. And use this as a standard to import into CNC machine tools. After many calculations and repeated tests, the machining accuracy of the installation hook is perfectly controlled.

When night falls, the tallest building in East Africa is shining brightly, and the commercial bank project has become the brightest "star" in the Ethiopian capital. These bright stars are assembled by 180,000 sets of point light sources. Because the curtain wall adds floodlight to the undulating diamond facets Difficulty in the arrangement and presentation of lighting fixtures.

The project team adopts a number of cutting-edge technologies such as irregular building display technology and edge continuous display to achieve the consistency of the overall display effect and the continuity of edge display, perfectly present the lighting effect, and successfully add a beautiful color to the city of Addis Ababa. Landscape.

In the process of construction, the project integrates Chinese intelligent and green architectural concepts, and strives to build the first truly modern building in East Africa.

The builders fully combined the local conditions of high altitude and sufficient sunshine to set up 112 solar lamps outdoors and 117 photoreceptors indoors. They can independently control the light and shade of the lights according to the intensity of sunlight to achieve an overall energy saving of over 30%.

In view of the hard water quality and more impurities in the local area, the project uses an air source heat pump to provide hot water instead of the traditional boiler hot water system, and adding a softened water system can further save about 15% of energy consumption.

The project actively implements "localized" management, employs outstanding graduates and laborers in the locality to implement the "one-to-one, one-on-one apprentice" teaching method, and cultivates technical talents through "transmission and guidance", providing more than 3,000 jobs in total.

An Ethiopian boy named Bale came to the project after graduating from college and studied with Liu Yiwu, the project's electromechanical manager. "In the beginning, the technology was not good, and the teacher would enlighten me without criticism. He taught me skills and made me become a talent quickly." Lay said. Today, Bale has become the "local technical backbone" of the project. He is responsible for the inspection and acceptance of electrical construction, and he can also assist Liu Yiwu to manage the construction quality.Editor/Ma Xue
