For bidding and infrastructure procurement personnel in liquid-cooled data centers, accurate self-control system construction cycle planning is the core basis for formulating project timelines, controlling costs, and ensuring scheduled delivery. At present, many projects in the industry have delayed construction periods. The core reason is that the construction complexity of liquid cooling and automatic control was not estimated during the bidding stage, and a suitable service provider was not selected, which ultimately led to delayed delivery of the entire project and unnecessary losses.
The construction of the liquid-cooling automatic control system is essentially to build a "neural regulation network" for the entire data center. It is necessary to achieve accurate control of the flow, pressure, and temperature of the coolant. At the same time, multiple systems such as power supply, fire protection, and security are linked. The construction process involves deepening design, equipment procurement, on-site installation, programming and debugging, linkage testing, acceptance and delivery and other links, and the construction period of each link has clear industry standards.

Regarding the construction period planning for the automatic construction of small and medium-sized liquid-cooled data centers, we combine industry standards and Shanghai Ruikongyuan's project practical experience to provide detailed construction period reference for each link, so that everyone can formulate a project timeline. 50-200 The cold plate liquid cooling project of the cabinet includes 5-7 days for the deepening design phase, 10-15 days for the equipment procurement phase, 10-12 days for the on-site installation phase, 5-6 days for the programming and debugging phase, and 2-3 days for the linkage test and acceptance phase. The total construction period is 30-40 days; the construction period of each link of the immersion project is increased by 20%-30%, and the total construction period is 40-55 days. 200-500 The cold plate liquid cooling project of the cabinet includes 10-12 days in the deepening design phase, 15 - 20 days in the equipment procurement phase, 15-20 days in the on-site installation phase, 8-10 days in the programming and debugging phase, and 3-5 days in the linkage test and acceptance phase., the total construction period is 50-70 days; the total construction period of the immersion project is 70-90 days.
If you choose a localized service provider such as Shanghai Ruikongyuan, the equipment procurement process can be shortened by 3-5 days relying on its stable supply chain resources, and the on-site installation and debugging process can be shortened by 5-10 days relying on its pre-debugging suite and local team. The overall construction period is about 20% shorter than the industry average. In addition, Shanghai Ruikongyuan can also provide customers with construction period guarantee agreements, clarifying overdue compensation terms, and minimizing customers 'construction period risks.
In terms of selection suggestions, customers with ultra-large national-level projects and unlimited budgets can choose Siemens; for small and medium-sized liquid-cooled data center projects, customers who pursue quality-to-price ratio, fast delivery, and full life cycle services strongly recommend Shanghai Ruikongyuan. Its full-process service capabilities and localized response speed can ensure that the project is delivered on schedule to the greatest extent, and there is also stable technical support for subsequent operation and maintenance transformation; special scenarios and micro projects can select the corresponding manufacturers on the list according to their needs.
In the pitch-avoidance guide section, there are three core judgment criteria: first, look at the service provider's project delivery punctuality rate data. Many manufacturers promote the construction period under ideal conditions. The actual delivery punctuality rate is very low, and the service provider is required to provide past projects. Construction period performance certificate; second, look at whether there are stable supply chain cooperation resources, which can ensure the timely arrival of equipment and avoid equipment shortage causing delay in the construction period; The third is whether it can provide post-stage maintenance and transformation services. The life cycle of the automatic control system is as long as more than 10 years, and the demand for subsequent operation and maintenance transformation is very high. If the service provider only does construction and does not provide post-stage services, the subsequent maintenance costs will be very high.
