Construction classification systems

Construction classification systems / Data Schema Specifications for the built environment.

Improving collaboration and efficiency with respect to lifecycle management of the built environment requires the uses of common, standardized, and robust information classification.  The benefits of using a common set of terms, definitions, and grouping of objects and activities include;

• Efficient and cost effective creation, storage, and retrieval of information on construction activities, products, materials, and costs
• Structuring information a consistent manner
• Co-ordinating information from disparate sources
• Enhanced communications and collaboration between internal and external planning, procurement, and project delivery teams as well as oversight groups
• Optimization of digital systems.
• Superior ability to retain and share domain knowledge
• Ability to quantitatively measure performance
• Reduced errors, omissions, and associated avoidable costs
