Effective Data Processing is Critical to Project Success

North American infrastructure challenges have been well documented.  In the United States alone 600,000 national bridges have an average age of 42 years with one in nine rated structurally deficient according to the American Society of Civil Engineers (ASCE).  Governments have underinvested in road and bridge infrastructure for decades and today’s funding falls significantly short of addressing the need.

One positive offset of constrained capital is the adaption of innovation – innovation in thinking and innovation in technology.

Ground Penetrating Radar (GPR) is an innovative technology that is increasingly utilized in infrastructure inspections across Canada and the US to provide condition data necessary for properly allocating constrained capital.  Data is used to show reinforcement bar corrosion in bridges, estimate asphalt and granular volumes over kilometres of highway and identify voids and delaminations in concrete.  This information is necessary for Quality Control in newly funded projects and determining priority of fund allocation in repair/rehabilitation projects.  These applications of GPR require advanced processing software and often sophisticated high-speed collection systems.

GPR processing and interpretation is a complex activity, where accuracy and quality hinge on a number of variables.  Antenna frequency and sample rate considerations are compulsory for project success, along with grid collection spacing and data processing experience.  Concrete with dense embedded features such as reinforcement bar and doweling requires imaging at optimal sample rates to ensure proper signal propagation.

To provide some insight into the processing activity visit our website to see comparisons of two examples of raw unprocessed GPR data profiles.  

3D Modelling a City - Taipei, Taiwan
Taipei is undertaking a significant project to become the first city in Asia to complete a 3D data-set for underground infrastructure. Kevin Vine, President of multiVIEW Locates was invited to present Ground Penetrating Radar technology and advanced 3D imaging techniques to Taipei City and Koahsiung City officials recently in Taiwan.  Taiwan has a tremendous utility record system and a need to apply accurate depth information for 3D modelling capability. Taiwan does not operate a utility One-Call system similar to the United States and Canada.


Supporting Infrastructure Maintenance With Non-Destructive Technology - By Kevin Vine


The combining of Ground Penetrating Radar data with traditional Infrastructure Coring creates a powerful data set for managing and prioritizing bridge maintenance and rehabilitation projects. multiVIEW's President explains further in the latest edition of Construction Executive, Tech Trends.
