Data Center Prefabrication

By standardizing the capacity, dimensions, interfaces, and main technical directions of data center functional units, we make these units possess the characteristics of industry productization and standardization. All modules can be prefabricated in Yimikang's Industry 4.0 smart factory. At the construction site, various unit modules can be flexibly assembled, reducing the need for on-site manual implementation and effectively shortening project delivery time.

Prefabrication Service Process

Standardized Design

The standardized design phase is a crucial part of the project implementation process, as the quality of the design directly affects the ease of subsequent prefabrication and assembly stages. This phase requires consideration of various influencing factors, such as cooling module capacity design, redundancy design, energy-saving indicators, equipment dimensions, and detailed process design like the positioning of pipeline system supports and hangers, as well as the segmentation of pipe sections. Incomplete consideration of these factors may lead to rework and modifications.

Prefabricated Model Establishment

Based on the approved detailed drawings and actual size parameters, the model is created to ensure consistency with the construction site, equipment, and pipeline accessories dimensions. During the initial stage, manufacturers provide size parameter drawings, and the model is created according to these drawings to ensure consistency between the model and the drawings.

Addition of Standard Parts

After the model is established, standard parts are added to appropriate locations within the system, such as supports and hangers, seals, and structural components. The placement of structural components should be convenient for installation and not hinder subsequent assembly and construction.  When selecting auxiliary materials for standard parts, they must meet regulatory requirements, such as fire resistance and waterproofing levels.

Prefabricated Model Verification

The data center's building structure is reviewed and measured, with the actual dimensions incorporated into the BIM model as 3D data for comparison. This step evaluates the impact of discrepancies between actual measurements and design values on site construction. Adjustments are made to the pipeline BIM model or existing structural components based on the actual measurements.

Segmentation Plan and Material List

Based on the adjusted or modified model, systematically divide the digital modules into sections and assign codes to them, and take into account transportation and assembly spaces to create processing diagrams, assembly diagrams, and overall assembly drawings.

After finalizing the plan, assign numbers to the prefabricated modules, export 1:1 CAD drawings, add dimension annotations, and view the drawings using a 3D viewing device.

Off-site Production

With the module parameter drawings available, proceed to prefabrication. During the prefabrication process, even a few millimeters of error can lead to misalignment during assembly. Therefore, strict control is necessary for the prefabrication. Detailed technical disclosure should be provided to the prefabrication personnel. Clearly explain each production step, and any error must be promptly reported for correction, in a bid to ensure the accuracy of all dimensional parameters for the prefabricated pipe sections.

On-site Assembly

The accuracy of on-site assembly is crucial. Export module positioning from the assembled model and use a total station for precise positioning and alignment to determine where the pipeline supports and brackets shall be installed. Obtain module information based on the QR code and proceed with the corresponding assembly and connection.
