Laval's site plan review process can be demanding, and imprecise boundary or elevation data can delay a project before it even reaches a permit officer. At PG Arpentage, we combine GPS, total stations, and LiDAR-equipped drones to deliver survey data precise enough to support the city's zoning and wetland review process. Our construction surveying in Laval service covers everything from initial topographic data to final as-built verification, giving your project team one point of contact from site visit to closeout.

Before a shovel touches the ground in Chomedey, Vimont, Duvernay, or Sainte-Rose, most files need accurate boundary staking, elevation data, and a site plan that matches the city's current zoning maps. Our teams start every mandate with a detailed topographic survey Quebec that reviewers can cross-check against current zoning maps, which helps reduce back-and-forth during the technical assessment. This groundwork is what construction surveying in Laval is really about, and it connects directly to our full range of construction surveying services across Quebec, supporting projects from the first site visit through final layout.

Laval's wetland protection bylaw shields high-value wetlands across the city, and any project near a protected area must confirm exact setback distances before design work can proceed. We pair a site layout and grading survey with LiDAR-equipped drones and georadar scans to map wetland boundaries, existing grades, and underground utilities in a single site visit. This is where construction surveying in Laval becomes essential, since a single misread setback line can force a redesign, and our drone and 3D scanning services for site surveys give reviewers the precision they expect.

As housing starts and mixed-use developments climb across Laval, larger sites need more than a single survey at the start of construction. Our land surveying services in Laval include continuous monitoring and movement tracking, so foundations, retaining walls, and adjacent structures stay within tolerance throughout the build. This ongoing oversight is a core part of construction surveying in Laval, and the same monitoring approach supports our construction surveying services in Montreal on comparably large projects.

A well-run site depends on a defined set of tools and repeatable workflows that keep every measurement traceable from first stake to final as-built. Here is what our teams bring to a typical mandate:
Total station layout : We set precise reference points for foundations, retaining walls, and structural grids before framing crews mobilize.
GPS control networks : Our crews establish site-wide coordinate control that keeps every subsequent measurement consistent across large or phased developments.
3D laser scanning : We capture dense point clouds of existing conditions, which speeds up design coordination on retrofit and infill projects.
Ground-penetrating radar : Georadar scans locate buried utilities and underground obstructions before excavation begins, reducing the risk of costly strikes.
Robotic layout with HP SitePrint : This system transfers digital plans directly to the ground with millimeter accuracy, cutting layout time on repetitive slab and wall patterns.
