Changji Qiya air-system installation package reaches candidate stage

CNCEC Fourth Construction published candidates on 2 November for equipment and piping installation labour at Changji Qiya Aluminium and Power’s compressed-air project.

Package FCC-XBZ-LWZB-2026-141/01 concerns installation labour associated with compressed-air piping and air receivers. It is a subcontract procurement milestone, rather than a separate award for manufacturing valves or pressure vessels.

Sichuan Xigefeng Construction Engineering ranks first, followed by Yueyang Ruhong Labour Services and Shandong Taochen Labour Services. The public notice provides no candidate prices, pipeline length, receiver capacity or valve schedule.

The notice period runs from 2 to 4 November, with written objections accepted through the procurement platform. The disclosed stage is evaluation of a labour package. It provides no evidence that the air system has completed installation, commissioning or entry into service.
