Mapping and pre-engineering

Engineering-grade utility data before you design.

CLI provides the subsurface utility data that de-risks a project before it is built. The team mapped the entire city of St. Catharines in 3 months, runs active operations in Oakville, and is expanding into Mississauga.

Pre-engineering services

The services behind a predictable build.

Six connected services carry a project from the first locate to a CAD-ready deliverable.

01

Pre-engineering locates

Expert subsurface utility locating performed early, before design locks, to prevent costly on-site conflicts.

02

Pre-engineering mapping

Field locate data digitally mapped and drawn into clear, actionable plans for the whole team.

03

Topographic surveys

Surface detail captured to support the design and the subsurface record.

04

Landbase mapping

The base mapping layer that ties the utility data to the real property fabric.

05

Drilling route guidance

Route guidance that helps directional drilling avoid the utilities already mapped.

06

CAD services

CAD deliverables for all of the above, ready for your design environment.

Mapped addresses across the St. Catharines program area

Where we are working

St. Catharines mapped. Oakville active. Mississauga next.

CLI mapped the entire city of St. Catharines, 20,000 addresses, in 3 months. Active operations continue in Oakville, and expansion into Mississauga is underway. Each program leaves the owner a permanent, legally defensible site record.

  • Identify utility conflicts before you break ground
  • Prevent costly on-site delays and work stoppages
  • A permanent, legally defensible site record

Field technology

Powered by GlobeSurv.

Field crews carry GlobeSurv™. It is a rugged handheld device with RTK-level accuracy, so the utility data meets engineering standards. The data goes from the field into your GIS, with 3D pipeline visualization and dynamic mapping in your asset management system. The device works online and offline and uploads direct to the server, so the crew can record data anywhere.

  • RTK-level accuracy to engineering standards
  • Field-to-GIS integration with 3D visualization
  • Online and offline capture with direct server uploads

Subsurface investigation

Investigation depth when the project needs it.

Delivered with our sister company Tierra Geomatic. CLI remains the named, accountable provider.

SUE

SUE investigations

SUE site investigations from Quality Level D through Level A, including test pitting for Standard A with full reporting.

Scan

GPR scanning

Ground-penetrating radar scanning where the record needs confirmation below the surface.

Inspect

CCTV inspection

CCTV inspection with NASSCO-standard reporting for sanitary and sewer lines, public and private, including sanitary lateral inspections for the City of Cambridge, Kitchener, and Waterloo.

Inspect

Manhole and invert inspections

Invert and manhole inspections reported to NASSCO standard.

Confirm

Dye testing

Dye testing and pipe-flow confirmation on public and private piping.

Private

Private locates and fault finding

Private locates for water, propane, septic, parking-lot lighting, natural gas, and communication cables, plus private hydro fault finding.

One accountable provider from the field to the file.

Mapping, investigation, and locate records connect through Locatorbase, so the data your engineers design against matches the record your crews dig against.

Before the design locks

Bring the project area and the data requirement.

Tell CLI the project area, the deliverable format, and the quality level the design needs.
