Utility as-builts can be some of the trickiest surveys to get right. Pipe runs, valves, brackets, offsets, crossovers it doesn’t take much for a drawing to end up looking like guesswork rather than a reliable record. Traditionally, surveyors have had to physically position themselves over or around every detail just to get enough measurements to form a usable plan.
That’s exactly why we’ve introduced the CHC Nav Vili i100 into our workflow because when you’re dealing with complex utilities, full context matters.
Why the Vili i100 Makes a Difference
The Vili i100 combines GNSS, scanning, and intelligent image-based point capture into a single, streamlined system. For as-builts, that means you’re no longer limited to isolated points — you’re capturing the whole environment.
Here’s what stood out during our recent utility as-built project:
1. Scan Data That Captures Everything
Rather than relying on a few manually measured points, the i100’s integrated scanning captured the entire pipework layout.Bends, valves, supports, junctions all of it was collected in one pass, giving designers and engineers a complete 3D dataset to work from.
2. Pull Survey Points Directly from the Imagery
With the i100, you’re no longer forced to stand directly over each feature.You can extract accurate survey-grade points from the high-resolution imagery after the fact.This is not only faster it’s safer and far more flexible.
3. Real-Time Visualisation for Instant Confidence
Surveyors can verify coverage on-site using the tablet interface. No more returning to site because a measurement was missed.What you see, you’ve captured simple as that.
Major Health & Safety Advantages
Utility and pipework environments aren’t always the most forgiving places to work. Tight spaces, uneven floors, trip hazards, hot pipework, active plant, awkward access the risks add up quickly.
Using the Vili i100 significantly reduces those risks.
1. Reduced Need to Enter Hazardous Zones
Because points can be taken from imagery, surveyors don’t have to climb over or manoeuvre around pipe systems.Less exposure = fewer incidents.
2. Minimal Time in Live or Operational Areas
Scanning captures large volumes of data fast.This shortens time spent around heavy machinery, operational utilities, or restricted-access areas.
3. No Awkward Measuring or Manual Handling
Traditional methods often require stretching, bending, or balancing in uncomfortable positions just to reach a measurement point.The i100 eliminates the need for those awkward moves, reducing musculoskeletal risk.
4. Better Situational Awareness
The ability to review scan coverage in real time means surveyors spend less time fixated on kit or measurements and more time aware of their surroundings.
5. Fewer Revisit Requirements
Every site revisit carries its own set of risks.Capturing a complete, accurate as-built in one visit reduces overall workforce exposure.
What This Means for Clients
When we deliver an as-built using the Vili i100, clients can expect:
A highly detailed 3D model rather than sparse points
Accurate geometry for design, maintenance, and planning
Better clash detection during future upgrades
Reliable documentation for compliance and asset management
A survey completed safely, efficiently, and in fewer site hours
It’s the combination of accuracy, efficiency, and improved safety that makes the i100 such a strong addition to our toolkit.
Using the Best Kit to Deliver the Best Results
At PQS Tech, we don’t just sell surveying technology we use it every day on real projects. The Vili i100 has proven itself time and again as a powerful tool for capturing complex utility environments with speed, clarity, and confidence.
If you need a detailed as-built of your pipework or utilities or want to explore how the i100 could support your own workflow our team is here to help.
