Ground Spatial provides continuous, automated reality capture for active construction sites in Christchurch. We turn raw weekly drone flights into an interactive 3D digital twin, allowing Quantity Surveyors and Site Managers to verify earthworks, track milestones, and catch design deviations before they become expensive variations.
Architects engage our $950 one-off package for concept feasibility, MDRS 3D daylight planes, and Council 3-Waters clearance. When your site breaks ground, hand our survey-grade baseline over to the lead contractor and QS team for weekly 4D earthworks verification.
Zero guesswork on contractor claims. Complete mathematical transparency between civil contractors, project managers, and quantity surveyors.
We fly your site every week on a strict, predictable schedule. Survey-grade multi-band RTK GNSS ties every point to official LINZ benchmarks with zero intervention required on your end.
Strict 7-Day Rhythm →A secure, cloud-hosted 3D globe of New Zealand. Click any of your active Canterbury sites to zoom in and view the millimeter-accurate point cloud in your browser with zero lagging.
CesiumJS + Potree Stream →Instantly see exactly what the contractor moved this week. Our M3C2 algorithms highlight excavations in red and fill in blue, providing undeniable visual proof for progress billing.
M3C2 3D Change Detection →We load your architectural CAD and civil engineering model (GLTF/IFC) directly over our weekly point cloud. See instantly if retaining walls, trenches, or foundations are out of alignment.
Instant Deviation Check →Draw a box or polygon over any dirt stockpile in your web browser and instantly generate a branded PDF report showing exact cubic meters, cut/fill balance, and surface area.
In-Browser jsPDF Engine →Access your massive 3D point clouds instantly on any laptop, iPad, or mobile phone via our secure Cloudflare-hosted portal with zero heavy desktop software required.
Cloudflare Pages + R2 Global CDN →Choose the capture cadence that matches your earthworks velocity. Cancel or pause anytime dirt stops moving.
Ideal for passive builds, council sign-off milestones, and low-velocity earthworks validation.
Ideal for active drainage, subgrade prep, and commercial foundations where progress moves quickly.
Continuous weekly monitoring for subdivisions, commercial builds, and active mass earthworks.
Retainers run on automatic calendar billing via direct debit or monthly Xero invoices. Pause or cancel with 7 days' notice anytime mass excavation pauses for winter or consent delays.
Scheduled UAV flights are routed across standardized regional clusters (Rolleston, Belfast, Rangiora, Halswell). Geographic batching protects our ultra-competitive $375–$450 flight rates with zero travel surcharges.
Need an urgent emergency progress capture before an unscheduled concrete slab pour or contractor claim dispute? Dedicated single-site dispatch is available for +$250 +GST with guaranteed 24h takeoff.
Canterbury wind gusts exceeding 25 knots or precipitation automatically slide flight operations to the next safe meteorological window with zero penalty fees or rescheduling charges.
