Xuzhou Metro Line 4 retenders shield-segment package with more than 20,000 rings
The Xuzhou Public Resources Trading Platform reissued a July 27, 2026 notice for shield tunnel segments on the continued civil works of Xuzhou Metro Line 4 Phase I. The notice covers shield segments, embedded channels and accessories, with a 412.9234 million yuan contract estimate, a 785-day supply period, and listed quantities including 17,535 type 1, 5,782 type 2 and 1,888 type 3 precast reinforced-concrete segment rings.
Key points
- The source is a reissued tender notice, not an award notice, and it does not identify the final supplier.
- The package lists three precast reinforced-concrete segment-ring types: 17,535 type 1 rings, 5,782 type 2 rings and 1,888 type 3 rings.
- The tender scope also includes steel segments, embedded channels and accessories, so the contract estimate is not a clean unit price for concrete rings.
- The stated supply period is 785 calendar days, with delivery tied to the progress requirements of the civil-work sections.
