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


Mapping and pre-engineering
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
Six connected services carry a project from the first locate to a CAD-ready deliverable.
Expert subsurface utility locating performed early, before design locks, to prevent costly on-site conflicts.
Field locate data digitally mapped and drawn into clear, actionable plans for the whole team.
Surface detail captured to support the design and the subsurface record.
The base mapping layer that ties the utility data to the real property fabric.
Route guidance that helps directional drilling avoid the utilities already mapped.
CAD deliverables for all of the above, ready for your design environment.

Where we are working
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.

Field technology
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.
Subsurface investigation
Delivered with our sister company Tierra Geomatic. CLI remains the named, accountable provider.
SUE site investigations from Quality Level D through Level A, including test pitting for Standard A with full reporting.
Ground-penetrating radar scanning where the record needs confirmation below the surface.
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.
Invert and manhole inspections reported to NASSCO standard.
Dye testing and pipe-flow confirmation on public and private piping.
Private locates for water, propane, septic, parking-lot lighting, natural gas, and communication cables, plus private hydro fault finding.
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
Tell CLI the project area, the deliverable format, and the quality level the design needs.
