01 — The Problem
Construction teams fly blind
— until it's too late.
9%
of total project cost lost to rework on complex MEP. Preventable with early detection.
10×
Cost to rectify post-installation vs. catching it before the next trade builds around it.
0
Tools that tell you whether a deviation measurement is reliable enough to act on. Until now.
◈
Deviations detected too late
Manual QA checks are infrequent and miss what accumulates across a complex structure. By the time something is flagged, the downstream trade has built around it.
◈
BIM vs. reality drift
As-built conditions diverge from the design model without anyone noticing. Coordination clashes emerge late, consuming programme and budget.
◈
Measurement without trust
Even when deviation data exists, teams cannot tell which readings are reliable. Acting on low-quality measurements generates false rework — a cost nobody tracks but everyone pays.
◈
Cascading schedule impact
One undetected structural deviation can hold up MEP, cladding, and fitout simultaneously. The compounding effect is rarely visible until it hits the programme.

03 — The Intelligence Layer
The reliability audit.
No other scan-to-BIM service does this.
The problem with deviation data: you can't tell which numbers to trust.
A 14mm plan shift might be a reliable measurement demanding immediate action — or measurement noise from poor scan coverage. Acting on both wastes money. Missing either creates risk. Our engine grades every measurement before you see it.
RELIABLE
Act on it
High confidence fit, sufficient scan coverage, ICP inlier rate above threshold. Deviation values are accurate and actionable.
CAUTION
Verify first
Marginal confidence or elevated uncertainty. Confirm with targeted re-survey before committing to rework.
UNRELIABLE
Re-survey required
Poor scan coverage or low ICP convergence. Do not issue rework instructions. Re-scan this element.

04 — Risk & Financial Value
What deviation intelligence
is worth to your project.
SGD 10M–25M
Avoidable rework exposure on a SGD 130M projectA single significant deviation undetected until downstream trades have built around it can cascade into weeks of schedule loss and multi-million correction costs. Early detection is risk management.
| Scenario | Without D-LIGN | With D-LIGN | Value protected |
|---|---|---|---|
| Shifted pipe spool detected late After downstream connection | SGD 12,000–40,000 | SGD 800–3,000 | Up to SGD 37,000 |
| Unreliable measurement acted on False positive rework instruction | SGD 5,000–15,000 | SGD 0 — flagged UNRELIABLE | Up to SGD 15,000 |
| Traditional dimensional survey Total station, manual inspection | SGD 1,500–3,500/day 5–20 elements/day | One scan session 50–500+ elements | 10–25× faster |
| Handover dispute — as-built record | No defensible record | Full audit trail | Dispute avoidance |
The engagement economics · On a typical MEP pipe rack with 50–200 elements, one scan session costs a fraction of a single rework event. The breakeven is preventing one deviation from becoming post-installation rework.

06 — Who We Are
The people behind
the intelligence.
Founder · Technical Lead
Yik Fei
Built the deviation intelligence engine from the ground up — ICP alignment, confidence scoring, reliability audit, and the full report pipeline. Operates the LiDAR scanner paired with total station on every project. Background spans construction BIM, LiDAR processing, and software development.
Our approach
We scan, process, and deliver. No outsourcing the intelligence layer. Every reliability grade comes from our engine running on our scan data. We own the full stack — from scanner to report.
Scanner
LiDAR scanner SLAM + Total Station
High-density point cloud with survey-grade georeferencing. Multiple control points per session for tight registration to BIM coordinate system.
Engine
Proprietary ICP-based deviation engine
Built specifically for construction tolerances. Confidence scoring, uncertainty quantification, and reliability grading per element. Not a generic point cloud tool.
