GIS can be used throughout the entire building lifecycle from planning and design through to operation. During the planning stage, GIS is useful for understanding geographic context and constraints. In design, GIS allows presentation of concepts to stakeholders and procedural modelling of design options. GIS supports analysis of design options and engagement. It also enables positional quality assurance. During construction, GIS supports site operations management. In operation, GIS facilitates facilities management and operational efficiency through integration with other systems like SAP and SharePoint. The customer's data requirements should be specified to ensure the right digital information assets are delivered.
