HD Laser Scanning to Support Broad Services at Ayres
HD laser scanning is among the many services available at Ayres Associates. Our extensive history of supporting diverse engineering applications allows us to approach each project as a unique mission with an individualized solution. Because Ayres Associates incorporates the experience of many disciplines in the implementation of the HD scanning technology, your project and budget can take advantage of the innovative solutions that we collectively offer.
HD scanning supports a wide range of applications for as-built survey and asset inventory:
-
Transportation design
-
Bridge and overhead obstruction clearance
-
Substations and utility infrastructure
-
Industrial facility maintenance
-
Change detection (load stress and settling)
-
Americans With Disabilities Act (ADA) compliance
-
Analysis of discontinuities
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 asset inventories, transportation design drawings, and quality control studies of as-built construction.
For bridge surveys, HD Laser Scanners provide an efficient approach to performing vertical clearance measurements and conformance of as-built conditions to design criteria. Vertical clearance surveys are critical to study and mitigate overheight collisions on bridges and overpasses- which can lead to costly damage to infrastructure and serious injury to motorists.
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 3D laser scanning. These compact systems can be operated in confined spaces and from multiple viewing perspectives to capture high-definition details of mechanical, electric, and piping (MEP) infrastructure.
3D models developed from the laser scans are being used by mechanical and electrical engineers to perform space and load bearing capacity analysis for expansion.
Architecture
The low-impact application of HD laser scanning mitigates safety and damage concerns as architects document the existing site conditions prior to 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 3D and run clash detection for potential conflicts.
