915 Building Laser Scan
HHPR provided land surveying and laser scanning services for the interior and exterior of the Ancient Order of United Workmen Temple building in Portland, Oregon. Prior to the start of the this project, HHPR also provided the owner and design team with a boundary survey and ALTA survey of the site.
HHPR surveyors then provided a combination of traditional surveying and laser scanning for the interior and exterior surfaces of this six-story, 50,000-square-foot building, including its basement. Utilizing the original work from the ALTA survey, traditional surveying methods were utilized to establish survey control on all levels of the building interior. At this time, sample survey data was collected on the building interior and exterior, which was later used for quality control measures to evaluate the scan data and modeling prior to delivery.
During the scanning process and prior to development of the Revit model, HHPR’s structural engineers toured the building to identify the structural components, which were required to be included in the final model. This structural evaluation was necessary due to the number of non-structural walls in portions of the building, which were not to be part of the final deliverable.
With scanning and data reduction complete, a BIM model was constructed in Revit utilizing the point cloud data produced by the scan. The final model included BIM 100 Level of Detail (LOD) elements from the BIM National Standards. Deliverables included point cloud, an LOD 100 Revit model, and Navisworks files. HHPR also provided post-delivery assistance for additional data extraction and interpretation of model elements.
