In order to determine the cause of the 355-meter skyscraper wobbling in Shenzhen as soon as possible, a series of tests, including vibration test, are planned to be carried out in the tower from June 1, the official account of Shenzhen municipal government reported on Monday afternoon. 

Such tests may cause the vibration of the building body in principle, but will not affect the structural safety of the building body, according to the report. 

At present, the monitoring, testing and identification work is still in process with a faster pace, and relevant information will be notified in a timely manner.

This came several days after the local Shenzhen government said that the structure of the SEG Plaza in Shenzhen meets the requirements as measured by its overall performance, citing new monitored data by professional institutions.

As of Tuesday noon, a wide range of monitored data shows the skyscraper remained normal and fell within relevant standards and requirements, read a statement posted on the official WeChat account of the local government, citing the conclusion of an expert team based on real-time monitoring of the skyscraper's subsidence, inclination and other metrics.

Several business owners in SEG Plaza, Shenzhen, told the Global Times on Sunday that logistics was disrupted there, but overall impact is under control since the shutdown of the skyscraper on Friday on potential safety concerns.

The building has been closed for safety checks after it began shaking last week. The Shenzhen local government said on Sunday that after monitoring some indicators of the building, including the tilt rate, experts found none has exceeded standard range as of Sunday noon. Further inspection and analysis of the skyscraper were proceeding at full speed, the government said in a statement online.

Li Xi, secretary of the Guangdong Provincial Committee of the CPC, and other provincial leaders arrived in Futian District, Shenzhen to conduct a research on how to further handle the swaying of the SEG Plaza and a special meeting involving experts was held, local newspaper Shenzhen Special Economic Zone Daily reported on Monday. 

Li emphasized that people's lives should be always put first and effective safety management of the building should be implemented, adding that it is necessary to seek truth from facts and form a joint investigation team of experts to conduct in-depth and comprehensive inspection and evaluation to come up with scientific conclusions as soon as possible, and at the same time, strengthen the release of relevant information to the public.  

Professional construction institutions have continued to monitor the building's subsidence range, tilt rate and other indicators on Monday. Live data collected onsite shows all numbers are normal on Monday and within the safety range, the official Weibo account of Shenzhen Internet Information Office said.

The 355-meter-high building in Shenzhen, South China's Guangdong Province, swayed last week for unknown reason. The building was closed on Friday for specific tests and inspections, said the management of SEG Plaza on Thursday.

SEG Plaza holds many tenants engaging in electronics business, such as trading electronic components, parts for smart phones and wearable products, and related auxiliary services. 

Some business owners said logistics in the plaza was interrupted by the closure of the building. "The operations of business owners in SEG Plaza were definitely impacted by the shutdown," Sun Zhenxiang, head of Shenzhen Yudamei Electronic, told Global Times on Sunday. He also noted that some business owners started to raise their price of products.

A staff of ACEZ Instruments Shenzhen Co surnamed Zhang told Global Times that their daily businesses were little affected because their shop in SEG Plaza is used for displaying samples of products, which can now be done through online communications. 

 "If the building is closed permanently or to be demolished, how to settle the large number of merchants working in the building is a problem," Sun said.

"Even if the SEG Plaza is closed permanently, the Huaqiangbei (electronics trading business) will not change," a worker surnamed Chen of Shenzhen Yaocheng Electronic Technology Co told Global Times.
