01 — Services
Every millimetre matters. We make sure yours are right.
ACR Tech provides end-to-end construction surveying services for high-rise, commercial, industrial, and civil projects across Canada. Our field crews and technology integrate directly with your project team from day one.
⊹
Construction Layout
Precise staking of foundations, columns, walls, and structural elements to design tolerances.
◫
As-Built Surveys
Verification and documentation of completed construction against design drawings.
△
Volume & Grade Control
Earthworks quantity calculations and machine-control data for civil and site work.
◈
3D Laser Scanning
High-density point cloud capture for complex structures, retrofit, and clash detection.
◎
Monitoring & Deformation
Continuous structural and ground movement monitoring throughout the build cycle.
⬡
Drone Photogrammetry
RTK aerial flights producing orthomosaics, DSMs, and survey-grade topographic maps.
⬢
LiDAR Scanning
Aerial and terrestrial LiDAR capture delivering dense, survey-grade 3D point clouds.
⊞
BIM Integration
Survey data delivered directly into Revit, AutoCAD Civil 3D, and Navisworks workflows.
