The Challenge: Verification at Scale
Our client is a 70-person structural engineering consultancy in Vienna, working on landmark projects including high-rise residential towers and university campus buildings.
As Inspection Engineer on major projects, they must verify that what gets built matches what was designed. Traditional methods—tape measures, theodolites, spot checks—couldn't keep pace with modern construction schedules.
The problem: you can't measure what you can't see. By the time concrete is poured and formwork removed, deviations are locked in. Discovering a problem after cladding installation can cost 10-50x more to fix.
On a 24-story residential tower, a concrete column on Level 14 was poured 23mm out of position. Traditional spot-check missed it. The deviation was discovered 6 weeks later during facade installation.
The Solution: Spatial Intelligence
Synapse OS Spatial Intelligence uses AI-powered photogrammetry to create engineering-grade 3D models from drones and smartphone scans.
The workflow is radically simple: site engineers capture photos with an iPhone, upload to Synapse, and receive a verified 3D model compared against CAD within minutes.
The Technical Breakthrough
- €50,000+ equipment cost
- Specialized operator required
- 4-8 hours processing per scan
- Manual CAD comparison
- Smartphone for elements & rooms, drones for large scale
- Any site engineer can capture
- 5-15 minute processing
- Automatic CAD overlay & deviation report
Synapse Spatial Intelligence achieves ±5mm accuracy for structural elements, validated against total station measurements. For most inspection purposes, this exceeds the ±15mm tolerance specified in ÖNORM B 2110.
Applications Across Project Lifecycle
100% verification of critical elements (columns, beams, shear walls) instead of 5% spot checks. Deviations flagged before next phase begins.
Weekly drone scans create time-lapse 3D models. Automatic comparison to 4D schedule highlights delays before they impact milestones.
Vienna's Gründerzeit buildings often lack accurate drawings. Spatial Intelligence creates measurement-accurate 3D models for renovation planning in hours, not weeks.
Crack mapping, spalling documentation, settlement monitoring. Each scan creates a permanent, measurable record for structural assessment reports.
Results After Six Months
87% Faster Verification
Site verification that took 2 days now takes 4 hours. Engineers spend time analyzing results, not measuring and documenting.
€2.1M Rework Prevented
Across 4 major projects, the system caught 47 deviations before they became expensive problems. Average cost-per-catch: €45,000.
100% Element Coverage
Every structural element is now verified, not just a 5% sample. The “we got unlucky” excuse is eliminated.
Competitive Advantage
The firm now offers “Digital Inspection Services” as a premium add-on, winning contracts against competitors who still rely on manual methods.
“We used to pray that our spot-checks caught the critical issues. Now we verify everything. Last month, we found a rebar placement error on Level 18 that would have cost €400,000 to fix after the facade went on. We caught it for the cost of a 10-minute iPhone scan.”
