Leica Geosystems Inc. unveiled BIM Field Trip solutions to help contractors extend the value of building information modeling (BIM) into the field and connect field information back to the model in the office.
BIM Field Trip can help in stages of BIM adoption such as concrete layout, MEP layout, quality assurance, renovation/retrofit and as-built applications. It also features hardware and software packages that allow for movement from 2D to 3D workflows to achieve common BIM goals.
BIM Field Trip solutions use Leica technologies such as the iCON robot 50 total station and the 3D Disto laser measurement tool.
The BIM Field Trip solutions are available in three levels to help companies bridge the gaps in the BIM processes.
BIM 101 uses paper or CAD files as a starting point. Tools such as the 3D Disto, iCON robot 50 and DISTO handheld laser measuring devices combined with intelligent, intuitive field and office software create an on-ramp to BIM for preconstruction as-builting, concrete layout, MEP layout, preconstruction as-builting and quality assurance.
BIM 102 provides an intermediate-level solution to help contractors improve their BIM workflows. For preconstruction as-builting, ScanStation high definition laser scanners capture existing building conditions in the form of near photorealistic, highly accurate point clouds that can be used directly in Revit for faster and more accurate modeling. For digital layout, high-precision iCON robot 50 robotic total stations combined with field software creates a “paint-by-numbers” installation in the field that reduces errors and provides a higher level of predictability of project outcomes. For MEP and interior BIM applications, the 3D Disto combined with specialized MEP software simplifies and streamlines interior layout. For preconstruction as-builting, layout and quality assurance, the “BIM One Box” Nova MS50 MultiStation performs robotic layout while the field software tracks the layout locations. When quality control checks are performed, any deviations are identified in real-time with a BIM delta report and can be scanned with the same device, producing point clouds that are automatically oriented and positioned so they flow back into the model perfectly aligned. This reduces post-processing so teams can focus on comparing field data with model data to avoid rework in the field.
BIM 103 is for contractors that are experienced in BIM. Hardware solutions such as the multistation, high-definition laser scanners and robotic total stations are combined with full featured field and office software to create advanced 3D workflows that streamline and optimize preconstruction as-builting, construction layout, and quality assurance as-builting. The “BIM One Box” multistation can use a single instrument for preconstruction as-built point cloud data capture, replicating highly accurate BIM layout points in the field, and then high-definition laser scanning for quality assurance as-builts for comparing with as-designed models to create a complete 3D BIM lifecycle.
