Zhejiang Engineering Design Co., Ltd. is committed to providing clients with distinctive value-added services.

In 2025 During the golden holiday period when the Mid-Autumn Festival and National Day—the “double holidays”—coincide, multiple general contracting project sites of Zhejiang Engineering Design Co., Ltd. have maintained a brisk construction pace, with work continuing unabated even during the festivities. Whether it’s the Juhua Western Project in Yumen, Gansu; the Caprolactam Project in Taiyuan, Shanxi; or the JuHua Poly‑Gathering project in Quzhou… PVDC In this project, the general contractor’s management team and the construction workers have been tirelessly working on the front lines. They have set aside precious time with their families, shouldering their responsibilities with dedication, going deep into the worksite to oversee safety, rigorously ensure quality, and energetically advance the construction. With a spirit of hard work, they are contributing to the Republic. 76 A gift to celebrate the year’s anniversary.

In the Yumen area of Gansu, construction on Sections 1 and 12 of the Juhua Western Project remains in full swing. As a key initiative for the company, work on each unit is progressing steadily according to schedule: the methane chlorination unit has reached structural topping-out, the monochloromethane unit has likewise completed topping-out, installation of the storage tanks for the intermediate‑product tank farm (hydrochloric acid) is proceeding smoothly, and construction of the drainage channels for the methane chlorination system has been finished. 90%...... Construction teams across all regions collaborate seamlessly, rigorously ensuring construction quality and advancing project timelines with swift, efficient execution.

The project owner is equally filled with emotion: “12 Once the month enters its cold‑weather phase, it doesn’t get light until 8:30 a.m. on site, and construction areas are completely covered in snow—conditions that must be managed carefully, with heating measures put in place. If work can even begin by 11 a.m., that’s considered good; by 5 p.m., it’s already over. Moreover, productivity is extremely low in the cold, and quality is hard to guarantee. Honestly, the amount of work done in seven days now doesn’t match what we used to accomplish in a single day. So right now… ‘ Double Festival ’ During the prime construction phase, everyone is working so hard, fearing they’ll miss the critical window and delay the overall schedule. ”

At the caprolactam project in Taiyuan, despite the holiday period, the scene that greets the eye is one of bustling, vigorous activity: equipment lifting, cable tray installation, and pipeline welding. ..... This project is based on an annual output of 10 From ten thousand tons to 20 In this technological upgrade project for an aging facility that has doubled its production capacity to 10,000 tons, the team faced a challenging environment: the original unit was densely packed with equipment and pipelines, adjacent to an operating plant, resulting in poor working conditions and significant construction risks. Despite these adverse factors—such as strong odors and an unsanitary site—the project team remained vigilant about safety at all times, maintaining unwavering commitment to safeguard the project’s security.       
  

The design building in Hangzhou is also brightly lit. Dozens of designers are working overtime to ensure the project stays on schedule. Given the low ambient temperatures at the general contractor’s site, it is necessary to complete the civil engineering works before the onset of the permafrost period. All disciplines are providing the conditions for civil‑engineering floor embedments, trenching, and other related requirements, while the architectural and structural teams are expediting the preparation of construction drawings. Due to the cold winter weather, It will affect construction efficiency. The process engineering team will coordinate with the site to provide the piping material list and single-line diagrams, enabling the early commencement of pipe prefabrication. Designers huddle in front of their computer screens, intently scrutinizing models and data, their fingers flying across keyboards and mice. With one overriding goal in mind—perfecting the design as quickly as possible to deliver precise, error-free drawings for on-site construction—so that each project can… “ Double Festival ” It can also proceed smoothly during this period.

“During the dual‑holiday period, on-site workers tend to become complacent; we must never let our guard down when it comes to safety!” At the project site, Mao Xuejun and Hu Xiao… Zhe Project managers including Xiang Xinhong, Xu Xin, and Zhang Shanying, together with the construction workers, have remained on the front lines, steadfastly holding their posts, and embodying the builders’ original aspirations through a sense of responsibility and commitment. “Although I couldn’t go home to share a reunion dinner with my parents, seeing that every stage of the operation was proceeding safely and smoothly put my mind at ease. By safeguarding safety, we’re providing the best possible assurance for the project, for the company, and for our nation’s anniversary.”

“‘ Double Festival ’ Everyone is working hard on the ground, and here we are, laying a solid foundation for the design—fighting side by side with our colleagues on the front lines. As I look at the designs unfolding on the screen, imagining them turning into tangible equipment and factory buildings that contribute to the project’s construction, even working overtime during the holidays feels deeply rewarding. We hope our designs will help ensure the project’s successful completion—that’s what gives us… ‘ Double Festival ’ The best gift ever. ” Designer Huang Xiaobin looked at the newly refined blueprints on the screen and said with a smile.
