High Definition Laser Scanning

 

Today’s design and construction projects require a new level of informed problem solving and decision making. High definition laser scanning (HDLS), coupled with the expertise of Wightman & Associates professionals who have used this technology on projects throughout the United States, provides you with information otherwise unattainable through conventional survey methods.
 
How it works
HDLS provides you with crucial detail when schedule, precise fit, access, and safety are a concern. The laser scanner looks similar to current survey instruments; however, it has field capabilities that include:
 
  • Capture of up to one million points per second
  • Simultaneous digital photography capture
  • 360-degree coverage at each set-up
  • Outdoor and indoor use
  • Capture of traditional survey targets allowing for real-world and site control coordinates
 
Following field work, the 3D data collected (point cloud) can create a variety of deliverables that give you the advantage in successful project development and implementation including:
 
  • 2D drawings and cross sections
  • 3D models
  • As-built documentation
  • Web-based viewing collaboration on any device, even cell phones
  • Free point cloud viewer with simplistic and intuitive capabilities
  • Building Information Modeling (BIM) and GIS integration
  • Clash and interference detection
  • Fly-through video
 
We would be happy to meet with you to review the data and answer any dimensional-related questions on the fly. In the realm of architecture, HDLS technology is used to address concerns such as floor flatness, structure verticality and the extent to which walls are bowed. In the realm of complex mechanical plants, HDLS technology is used to address concerns such as clash detection, design fit, and isolation distances.
 
Why use HDLS
Laser scanning is well-suited for capturing as-built data in settings where safely collecting data is an issue, in spaces not easily accessible, and in complex environments. For instance, it is the ideal tool of choice for as-built surveys in electrical substations or complex mechanical plants. Because the laser scanner automatically captures incidental data, the technology eliminates the need for repeat site visits for collection of additional data not originally known to be needed.
 
It can save you time and money by resolving problems during the design phase rather than having to remediate issues in the field. With complete and accurate measurements at the beginning of your project, you can reduce contingencies in the bid process, streamline critical decisions that drive the project schedule, and more quickly identify obstacles which hinder smooth workflow between disciplines.
 
A few of the ideal applications for HDLS technology include:
  • Intricate environments such as those with extensive piping, ductwork, and conduits
  • Building interiors and exteriors
  • Infrastructure components such as bridges, dams, and road intersections
  • Pre-construction interference checks and clash detection
  • Substations, utility towers, and transmission lines
  • Stadiums, theaters, and auditoriums
  
Why Wightman
Wightman & Associates is among a select number of firms in the United States that provide HDLS as well as architecture, engineering, surveying, GIS, and building information modeling (BIM) under one roof. Because of this unique combination of in-house expertise and technology, you can be confident in the level of service and deliverables we provide.  
 
Spearheading our HDLS efforts is David Langley, the top talent in the laser scanning industry.  David has 14 years of experience in the laser scanning industry – including seven years as a product manager and applications engineer for Leica Geosystems, a pioneer in the world of high definition laser scanning. He was recruited by both Leica and Wightman for his unique mix of technical expertise and communication skills that he provides to any team seeking to use HDLS technology to address their complex measuring needs.
