HD SCANNING: THE APPLICATIONS Click Photo to Play Video Transportation The ability to quickly capture detailed information from HD laser scanners makes this an important tool for surveying and analyzing transportation infrastructure. The long-range capacity of laser systems set up at strategic vantage points enables a surveyor to effectively record precise measurements of hard- to-reach locations. HD laser scanning is being effectively and efficiently used for generating bridge clearance reports, asset inventories, transportation design drawings, and quality control studies of as-built construction. Substations and Electric Utilities Electrical utility owners and designers use HD laser scanning for asset inventory on existing facilities, future expansion capacity, existing structural conditions and analysis, and as-built collection for maintenance. HD laser scan data can be integrated into existing aerial LiDAR data to create a more accurate and holistic data set. Collection of data using HD laser scanning greatly reduces the need for a facility to be taken out of service for data collection and allows entire sites to be captured safely and efficiently. Industrial Facilities Feature extraction and modeling of assets for industrial building information modeling (BIM) is supported by precise, high-definition 3-D laser scanning. These compact systems can be operated in confined spaces and from multiple viewing perspectives to capture HD details of mechanical, electric, and piping (MEP) infrastructure. 3-D models developed from the laser scans are being used by mechanical and electrical engineers to perform space and load-bearing capacity analysis for expansion. Scans can be completed without taking facilities offline. Architecture The low-impact application of HD laser scanning mitigates safety and damage concerns as architects document the existing site conditions before restoration and rehabilitation projects. The highly detailed information captured by these systems also reduces costly site revisits and enables remote quantification of assets and features. The ability to measure crucial “one off” items on existing buildings for replication in the design process greatly increases the quality and accuracy of the end product. Architectural designers and MEP engineering staff have the ability to design in 3-D and run clash detection for potential conflicts. 4 | SCANNING FOR INFRASTRUCTURE Click to activate video PROJECT: RIVER WALL & HARBOR PARK The City of Kewaunee, Wisconsin, hired Ayres Associates to provide preliminary design services for the Kewaunee River sea wall and Harbor Park’s boardwalk, parking lot, and associated amenities. Restoration of the Kewaunee River shoreline will be designed in accordance with the input of stakeholders. The proposed work includes removing the sea wall and replacing it with an anchored sheet pile wall. Harbor Park improvements are expected to include approximately 1,350 feet of boardwalk leading out to the lighthouse, along with six fishing platforms, pedestrian lighting, parking lot improvements, and associated landscaping. By fusing multiple data collection methods (remote sensing, HD scanning, and traditional survey) Ayres was able to very precisely document the existing conditions of the entire project area in 3-D, including the harbor bottom and associated wall. The use of HD scanning will enable planners and design staff to effectively integrate new design elements into the backdrop of the existing landscape and built environment. AYRESASSOCIATES.COM | 5
