Yangzhou new energy project completed through innovation and collaboration

Yangzhou's new energy phase one project, funded and constructed by CCCC Second Harbor Engineering Company, is situated in Shiqiao town, the economic development zone of Yangzhou in Jiangsu province.

Covering a construction area of approximately 330,000 square meters and boasting a building area of around 250,000 square meters, the project involves a total investment of about 2.3 billion yuan ($316 million), with 24 individual buildings including battery production plants, cutting workshops, power stations and integrated buildings to form a vast and intricate industrial cluster.

The seven-month construction journey cut its way through numerous challenges and difficulties, including the construction of around 12,000 tons of steel structures and the installation of 920,000 meters of mechanical and electrical pipelines. With tight timelines, complex processes and extreme coordination challenges, the construction team faced an uphill task.

To overcome these challenges, the project team extensively utilized Building Information Modeling (BIM) technology. By simulating pipeline installations, they preemptively identified 22,000 collisions in the construction drawings, employing strategies such as pipeline rearrangement and elevation adjustments to avoid "traffic jams" of mechanical and electrical pipelines during construction. This optimized spatial management in both horizontal and vertical directions, reducing the risk of cost escalation and delays due to poor construction coordination while enhancing construction quality.

At the construction site, nearly 3,000 workers were busy during peak periods, while more than 500 sets of mechanical equipment reverberated and dozens of construction vehicles moved incessantly. To manage such large-scale operations efficiently, the project team innovatively introduced new modes such as "QR code + drawing management", "QR code + process management" and "QR code + model demonstration". These codes acted as intelligent navigators, consolidating scattered individual disclosures into a vast and orderly comprehensive technical disclosure network. Workers could easily access detailed information on process flows, construction drawings and key construction points by scanning the QR codes, ensuring clarity on daily tasks and operating procedures.

In a bid to expedite commissioning and productivity, the project adopted a multi-pronged approach. More than 100 flatbed trucks entered the site in procession, eight material receiving points operated simultaneously with material personnel working round the clock, and the laboratory raced against time to complete concrete structure inspections for nearly 1,000 frame columns across 28 individual units in just 20 days, safeguarding the construction progress. The collective efforts of all personnel in racing against time led to several construction miracles, including 8,000 meters of static pressure pile construction in a single day and the installation of 130,000 square meters of steel structure in a month. Achievements like completing 194,358 meters of pile foundation construction in 43 days and achieving the structural topping-out in 70 days were recognized with accolades such as "Civilized Construction Site" in Yangzhou and being listed among the second batch of high-quality structural engineering projects in the city. The Phase One project of Yangzhou New Energy successfully passed the completion acceptance in early April.

This success marks just the beginning as Yangzhou's new energy phase two project continues to progress rapidly, solidifying Yangzhou's position as a leading city in solar energy and new energy developments.
