The Jiujiang municipal government published an August 18, 2026 China Jiujiang Web report saying Jiangxi Sanfang Building Materials' new precast-component project in Hukou High-tech Industrial Park was advancing with two steel-structure workshops completed and early production under way in finished areas. The source says the project is using an early-production approach for 400,000 niu-wang-zi concrete armour blocks, with full production planned by the end of 2026.
China Railway Group reported on August 7, 2026 that the Shanghai-Nanjing-Hefei high-speed railway's Hefei hub introduction works completed box-girder erection after the final single-line simply supported box girder was placed at the Kuadianbu River grand bridge site in Feidong County on August 5.
PowerChina's Sinohydro Bureau 14 reported on August 6, 2026 that shield-segment steel mold and rebar-cage samples for the Shenzhen-Huizhou intercity rail Lot 1 Qianbao-Wuhe project passed first-article inspection on August 4, moving segment production toward batch manufacturing.
China Railway Group reported on August 13, 2026 that the Ghana NB project completed erection of the first span of 40-meter prestressed-concrete T beams at Navuni Bridge on August 5 local time. The bridge uses five 40-meter simply supported spans, with 25 T beams planned across the full 200-meter bridge.
The Qianjiang municipal government carried an August 3, 2026 report that the Dongjing River green transport corridor project installed the first precast girder for the new Dongjing River bridge on July 31. The report says the milestone moved the bridge into superstructure works after lower-structure construction was largely complete.
The Wuhu Public Resources Trading Center published a July 9, 2026 notice for Wuhu Economic Development Zone's 2026 engineering-project prefabricated procurement package.
