Overview
Convex Geomatics Ltd. specializes in Construction Layout, Monitoring & Control for building, civil, and industrial projects across Calgary and Western Canada. We establish tight primary/secondary control, perform site calibrations with independent check shots, and maintain a single source of truth so field crews, designers, and contractors are working from the same coordinates and versions at all times.
Construction Layout. From gridlines, foundations, anchor bolts, and embeds to utilities, curb & gutter, paving, and earthworks, our crews use GNSS RTK/PPK and robotic total stations to stake, verify, and document to your specified tolerances. We provide clear stake reports and hold-point sign-offs, plus rapid re-stakes as designs evolve to keep schedules on track.
Monitoring & Verification. We deliver settlement and deformation monitoring using prisms/targets, reflectorless shots, and scan-to-model comparisons—producing trend charts, deviation heatmaps, and alert thresholds for proactive decision-making. Critical as-builts (inverts, slab elevations, rails, embedded plates) are checked against design with transparent QA/QC and independent checks.
Machine Control & Data Management. We build and maintain machine control models—surfaces, alignments, linework—and manage revisions/versions so operators always have current files. Controller-ready deliverables are provided for major platforms (e.g., Trimble, Topcon, Leica), along with CAD handover (Civil 3D/MicroStation) and a clear change log for full traceability.
*Subject to specification, site conditions, and control quality.
