How can project managers and designers use the information created by a 3D map? Project managers and designers can use information created by a 3D map across the project lifecycle. Early in the project, the 3D map can help scope the project by providing a comprehensive baseline understanding for the project environment. During the project, it can be used to plan and sequence demolition, construction and equipment installation. As the project reaches conclusion and commissioning, the 3D map can then be used to represent the facility as it was actually built, enabling it to both confirm the finished project meets specifications and be used as an ongoing reference for maintenance and operations.
What tools or technologies do foodservice equipment and supplies dealers need to create an effective 3D map? 3D maps are most commonly created using lidar (light detection and ranging) and optical scanning technologies. The scanning hardware can range from a high-definition, industrial-grade lidar scanner to the sensors provided in high- end mobile phones. Both ends of the spectrum provide the tools to create a 3D map, but the difference is in the detail and accuracy. If timeliness and cost are drivers, then phone scanning is more appropriate. Optical scanning tools that use high-definition sensors and location-aware hardware provide much of the accuracy of high-grade lidar while benefiting from the lower cost and quicker data capture offered by consumer-grade mobile phone cameras and lidar sensors.
Are there different levels of 3D mapping?
The American Institute of Architects has defined levels of development (LOD) for 3D modeling. Each model provides benefits for distinct stages of project development. The levels include: • LOD 100: Concept design • LOD 200: Approximate geometry • LOD 300: Precise geometry • LOD 350: Greater detail and construction documentation • LOD 400: Fabrication and assembly • LOD 500: As-built model
