Product Data

The Product Data module provides essential data basis for optimization design, engineering quantity and cost generation of entity modules in Greenwich. This module is comprised of material library, PBOM template, model library, unit price library, and cost estimation template.

Each sub-module in the Product Data module is maintained by professional data administrator of Greenwich. So this section provides only a brief introduction on the functions of each sub-module.

Material Library

Material library includes the facility and project service materials and material groups used in the wind farm project. Each material or material group is assigned with a specific number for recognition in the project design.

The hierarchy in the material library is consisted of four levels, and the materials are embedded in the fourth level. Operations in each level of hierarchy are listed as below:
  • Double-click the item in the first or second level to check and edit its substructure.
  • Double-click the item in the third level to open the material group details page. On this page, check the material group details, add material group, and import material group(s).
  • Double-click the item in the fourth level to open the parameters page of material. On this page, check the material details, add material, import/export material, and enable/disable the material.

The material library administrator maintains the material data in this module.

PBOM Template

PBOM template provides the bill of materials needed in the wind farm life circle design, engineering, purchasing, and cost assessment process, and all material groups composing this bill. In this template library, all the templates are categorized as ten project unit, including route, platform, foundation, turbine and tower, substation, WTG transformer, other projects in wind farms, mast and outgoing line. Four levels comprises a project unit structure.

  • Double-click the first three levels to check and edit its substructure.
  • Double-click the fourth level template to open the PBOM detail page. Check the material groups included in this template.

The PBOM template administrator maintains data in this module.

Model Library

Model library collects the PBOM models used in some specific project design scenarios. Its structure is the same as the PBOM Template module.

  • Double-click the first three levels to check and edit its substructure.
  • Double-click the fourth level template to open the model detail page. Check the models applied in the specific project, and edit, add, enable/disable these model.

Unit Price Library

Unit price library collects the material price with various properties in the specific quarter. By defining the filters, you are enabled to search for your desired material price with efficiency and accuracy.

The unit price library administrator is responsible for importing price, freezing invalid price, checking log file, and updating recommended algorithms of unit price library.

Cost Estimation Template

The cost estimation template module embodies engineering quantity template of professional facilities and materials used in feasibility study, cost estimation template in feasibility study, and engineering quantity template of unit project.

The model administrator configures the mapping relationships and calculation rules between various templates and PBOM templates.
