Guangzhou Hanyuan Construction Engineering Quality Inspection Co., Ltd
Guangzhou Hanyuan Construction Engineering Quality Testing Co., Ltd. (hereinafter referred to as "the company" )Formerly known as the Central Laboratory of the Second Bureau of water resources and Hydropower of Guangdong Province, it was founded in 1952 at Gutianxi hydropower station, mainly responsible for the quality inspection of water conservancy and Hydropower Engineering Construction in Guangdong Province. In April 1990, the qualification grade was approved by Guangdong Provincial Water Conservancy and electric power department as building material grade I and geotechnical engineering grade II test qualification; In 1993, it was approved by Guangdong Provincial Construction Committee as the second grade qualification laboratory. In 2004, with the approval of No.2 Hydropower Bureau, Guangzhou Hanyuan Construction Engineering Quality Inspection Co., Ltd. was established as an independent legal entity to carry out independent engineering quality inspection. In January 2020, it was incorporated into 亚博yabo888vip网页版登录,亚博yabo888vip官网进入,亚博yabo888vip,., Ltd. The company has water conservancy engineering concrete engineering grade A, geotechnical engineering grade A, measurement grade B, metal structure grade B qualification, mainly undertakes domestic water conservancy and Hydropower Engineering, municipal engineering and construction engineering material testing, structural testing, foundation testing, monitoring and other testing tasks.
