multiVIEW was pleased to contribute to the latest issue of Canadian Underground Infrastructure. In this article, Kevin Vine, President of multiVIEW describes how Subsurface Utility Engineering (SUE) plays an integral role in the design phase of large Rapid Transit projects….
Transit infrastructure projects often occur in areas of high congestion, both above and below ground. Effective project design depends on the ability to locate all buried infrastructure within the project site to make informed decisions around utility accommodation, coordination and relocation. Decades ago, this process involved collecting utility records and assuming that they were accurate, which introduced a wide margin of risk for transit-related projects.
Thurber Engineering Inc.I have found multiVIEW’s data collection, analysis and reporting to be thorough, comprehensive and professionally delivered. The GPR data has always proven extremely useful to our projects, providing us with a substantive representation of subsurface conditions that can be factored into the construction design process.
Providing subsurface visibility that eliminates risk
multiVIEW Locates has successfully empowered hundreds of transit projects across the province of Ontario including the Union Station Rail Corridor (USRC), Eglinton Crosstown Light Rail Transit (LRT), Finch West Light Rail Transit (LRT), and the Mississauga Bus Rapid Transit (BRT). Partnering with organizations including Metrolinx and the Toronto Transit Commission (TTC), we support complex transit projects through our Subsurface Utility Engineering (SUE) investigation, combining records research with geophysical methods, vacuum excavation and land survey techniques.
Insights acquired from these activities converge to reveal utility data that can be counted on as accurate and complete. As transit projects can often be scrutinized for schedule and cost overruns, the SUE process helps to mitigate unplanned utility relocation costs and project schedule impacts by revealing potential conflicts in the early stages of design.
Taking the danger out of transit infrastructure excavation
multiVIEW Locates has supplied ongoing utility locate support to transit organizations throughout Ontario for many years and is well versed in complying with municipal and transit specifications. We deploy quickly from four strategically situated offices and apply advanced techniques that include Electromagnetic (EM) Induction and Ground Penetrating Radar (GPR) to accurately locate subsurface infrastructure at various sites.
We will locate and mark fibre communications, high voltage electricity, high pressure gas mains, water and sewer pipes, switches, pressure plates and other complex infrastructure. We will also coordinate with project stakeholders, secure permits and develop project specific Traffic Management and Health & Safety Plans.
Safe, efficient concrete scanning, results delivered in real-time
multiVIEW Locates helped pioneer early applications of concrete scanning in the 1980s, using Ground Penetrating Radar (GPR). Today, our GPR applications are vast and include concrete scanning for bridges, roads, buildings and other structures. We can identify rebar spacing, rebar depth and concrete thickness prior to demolition.
GPR can also be used for void detection, bridge deterioration analysis, post tension cable imaging, concrete and asphalt thickness. Unlike X-Ray, no harmful radiation is emitted and a clearance area is not required. Results are delivered in real-time and can be presented in plan view, profile view and 3D.
We’ve successfully empowered hundreds of transit projects across Ontario including the Eglinton Crosstown LRT. Our services help to mitigate unplanned utility relocation costs and project schedule impacts by revealing potential conflicts in the early stages of design.
