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.

• 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.
