Smooth capping

Yangzhou Digital Center module project (China Unicom Eastern Cloud Computing Power Center) is the first large-scale modular professional contracting project undertaken by Chenxin Heavy Industry (Jiangsu) Co., Ltd (hereinafter referred to as CXHI), with a total construction area of 46,000 square meters.

Despite the tight schedule and high construction quality requirements, CXHI braved the difficulties, take the initiative to undertake the responsibility. According to the plan, CXHI needs to complete the structural roof-sealing in 36 days after taking over. CXHI prepared the detail plan, closed liaised with the five module equipment assembly bases, 24 hours supervise the assembly progress of each module, and control the time node of module supply on critical path to ensure the smoothly on-site lifting.

The workshop worked overtime and finally successfully delivered the first-batch components to the site on March 25, 2023. Leading by the chief engineer, CXHI try the mechatronics installation for the first time and solve all the technical problems satisfactorily.

Module preinstallation

The constructor re-adjusted the positioning plate on site and finally ensured the successful completion of the first lifting on March 26, 2023.

Field adjustment basis

Bow site

To keep the project on schedule, every day is crucial. It came a transition period from spring to summer, typhoons and rainstorms are frequent. Considering the various possibilities, project team prepared in advance to prevent the fire-proof layer and electromechanical equipment from damaging by the rain. 

Catch a typhoon

With the cooperation of the workshop and project team, the project proceeded rapidly, especially the day and night site construction, the project team continuously optimized the installation and overall acceptance plan, from the beginning of handling 5 modules a day, to the peak of handling 62 modules a day, and finally completed the roof-sealing one week ahead of the schedule. 

It will be closed on April 30, 2023

The project duration is the most concerned issue for the customer and CXHI, and many factors seriously restricted the progress of the project:

The project is a modular structure, requiring accurate positioning of all bolts with large quantity of about 80,000 sets, and the construction space is limited, installation and fastening positions are blocked, to ensure the construction schedule, CXHI customized special wrenches and additional 60,000 pieces of cushion plates dedicated for the project.

The site fire protection requirements are extremely high, and the fireproofing coating of installed modules must not be damaged, but the risk of damage will be increased due to the longtime handling and lifting process, narrow traffic path and the large-scale crane hoisting. Also, the transportation road from the storage yard to the site is the only driving school test road in Yangzhou City, which brings great difficulties to module handling.

Due to the mismatch between the supply sequence defined in the early stage and the actual situation of on-site lifting, a large number of modules which waited for installation were overstocked in the storage yard. CXHI communicated with customers proactively, adjusted and optimized the lifting plan promptly according to the site conditions, and increased input to ensure the smooth supply of modules from the workshop to the storage yard and finally to the site.

The CXHI quality inspection team went deep into the module equipment assembly base, carried out a comprehensive quality inspection for each module's appearance size, hole position, hanging lug welding quality, module number and orientation marking, painting and fireproof coating, etc., recorded the data in detail and reported if any problems, and timely feedback to the site to ensure the smooth installation for each module.

The construction team selected veteran and skilled worker, gathered the backbone strength of each project, followed the project plan, united as one, cautious and conscientious, willingly bore the burden of hard works, carried out the team labor competition, seamless connection between day shift and night shift to ensure the workload of each shift, did not get off work until finished site lifting, made preparation for the next team operation, which showing the excellent quality of striving hard , being good at fighting against difficulty, daring to take responsibility and taking care of the overall situation.

CXHI is committed to fabricating high-quality steel structure, adhering to the concept of service upmost, and actively seeking best solutions for customers, striving to make  breakthroughs in new fields, and injecting new impetus into the development of CXHI.
