Engineering construction company is a pure construction unit, bureau level, headquartered in Beijing. Last year, it reorganized Jianyi and PetroChina Qingdao Refinery and Chemical Design Institute. The management department is a newly established bureau-level unit with few people, and the leaders are basically transferred from various units. The person in charge is Wu Hong from the Pipeline Bureau Design Institute. This unit is now mainly responsible for pipeline investment throughout the country. To put it bluntly, it is the place where oil and water are intercepted, and all material purchases must be approved by them; Pipeline Bureau is also a construction unit now, with excellent CPEE design institute. Now it is a Grade A comprehensive design institute, and there are less than a dozen Grade A design institutes in China. A bad place is Langfang, and the treatment is quite good.
