Subsurface Utility Engineering (SUE)

We’ve performed SUE projects long before it was a recognized civil engineering practice by ASCE. Our tried and tested methodology is based on decades of progressive experience that assures clients receive the highest standard in quality subsurface utility data and visual maps that fuel strategy development, the engineering design process, and construction efficiencies.

Subsurface Utility Engineering (SUE)

Effective engineering design depends on reliable information about existing site conditions. Subsurface Utility Engineering (SUE) develops project-specific utility information to support planning, design, coordination, relocation and construction activities.

multiVIEW combines records research, field investigation, utility designation, surveying and targeted utility exposure, as appropriate, to develop and document subsurface utility information for defined project requirements.

Expertise that Adds Value

multiVIEW brings decades of experience in utility investigation, mapping and infrastructure data development to SUE projects across Ontario.

Our teams combine Engineering, Geophysics, field investigation, surveying, data management and technical review to develop utility information suited to the requirements of each project. multiVIEW is also a prequalified provider for numerous municipalities and infrastructure organizations, supporting projects ranging from focused investigations to large, multi-phase capital programs.

Quality Levels and Technical Confidence

multiVIEW’s SUE work is performed with reference to the current ASCE 38 standard and its established framework for classifying subsurface utility information by Quality Level.

Quality Levels D through A reflect different sources and degrees of investigation, from existing records and visible surface features through geophysical designation and targeted physical exposure.

Selecting the appropriate Quality Level depends on the project objective, design stage, site conditions and the level of information required.

multiVIEW applies records research, field observation, geophysical methods, surveying and vacuum excavation as appropriate to the investigation. Information developed through these methods is reviewed, correlated and documented to provide the project team with a clearer understanding of known utility conditions, identified conflicts, and areas where additional investigation may be warranted.

Because subsurface investigation is subject to site conditions, utility characteristics, access and the physical limitations of available technologies, no single method can resolve every condition. Our approach is to apply appropriate investigative methods, professional judgment and quality controls to develop and clearly communicate the information reasonably obtainable within the defined project scope.

Integrated SUE Project Delivery

multiVIEW combines Engineering, Geophysics, surveying, utility investigation and project management capabilities to coordinate SUE programs around defined project requirements.

The appropriate investigation effort is determined by factors such as project stage, site complexity, available records, design needs and the level of utility information required. Depending on the scope, multiVIEW can coordinate records research, field investigation, geophysical designation, surveying, targeted utility exposure, CCTV investigation, mapping, data management and preparation of professional deliverables.

Information developed through each stage is reviewed and consolidated to document the utility conditions identified within the project limits and the Quality Levels achieved.

We used to rely on disparate data to gain an understanding of subsurface assets. Whenever a change would occur, the area would be re-surveyed and data would be stored in various formats. By applying Subsurface Utility Engineering, we’ve created a database of high quality data that can be used by future contractors for years to come.

From Field Information to Project Deliverables

multiVIEW’s CAD and technical teams consolidate information developed through the investigation into project-specific drawings, datasets and supporting documentation. Deliverables are prepared to reflect the applicable SUE Quality Levels, defined project scope, relevant standards and customer specifications.

The resulting information provides the project team with a documented representation of the utility conditions identified through the investigation, together with the context needed to understand how that information was developed.

The multiVIEW Advantage

01

A highly qualified team of professionals

We’re authorized by the Association of Professional Engineers of Ontario (PEO) in addition to the Association of Professional Geoscientists of Ontario (APGO). We offer P.Eng and P.Geo oversight on all project processes and deliverables.


02

Tried and tested project methodology

Our project methodology is based on over 30 years of experience in project planning and coordination. A focus on QA/QC ensures timely delivery, completeness of in-field area coverage and the production of high quality visuals and reports.


03

Self-performance capabilities

We’re able to self-perform all four SUE quality levels including QL-A “daylighting.” Minimizing or eliminating the need to manage subcontractors decreases risk and the possibility of project delays.


04

An investment in continuous training

Our highly trained technicians undergo various levels of training including ORCGA Damage Prevention Technician (DPT); Certified Project Management; Confined Space Entry (CSE); Rail Safety and Electrical Safety Authority (ESA).
