Large, busy zones
Stations suit zones where a lot happens between visits: cores, decks, excavations.
Fixed LiDAR stations
What Happened on Site While Nobody Was Walking It?
A walk records the moments someone was on site with a camera. Pours, lifts and backfills happen in between. Fixed LiDAR stations scan the work zone every 15 to 30 minutes, round the clock, with nobody there to start them, and every scan lands in SpatialSense.

The short answer
Walk-based capture is periodic: however good the walk, it covers the moments somebody was on site holding a camera. A fixed LiDAR station keeps scanning. It produces a full point cloud of its zone every 15 to 30 minutes, around the clock, with no operator, and SpatialSense keeps every scan dated and placed, so work that was covered the same day is still in the record. Our longest-running installation, on a public works site in Hong Kong, has been scanning for more than two years.
What a fixed station adds
- The hours between walksPours, lifts and backfills that happen between visits are still in the record.
- No one to sendNo walk to schedule and no operator on site to start a scan.
- Dated and placedEach scan arrives georeferenced and dated, ready to open next to any other.
- Next to your walksFixed scans, 360° walks and drone flights sit in the same project.
- Watched remotelyStation health is reported and problems are fixed remotely, because monitoring that quietly stops is worse than none.
How continuous monitoring works
The station does the capturing. SpatialSense is where the scans end up, next to everything else on the project.
-
On a pole, not on a person
LiDAR stations are mounted on poles or structures that look over the working zone.
-
A scan every 15 to 30 minutes
Each station produces a full point cloud of its zone every 15 to 30 minutes, day and night, with nobody on site to start it.
-
In the record, dated
Every scan lands in the project, dated and placed, next to your 360° walks and drone flights.
Why does the record go blank between walks?
Reviews of site-capture tools praise the walk. The gap is everything that happens when nobody is walking.
Work gets covered
Once a pour is finished or a trench backfilled, what is inside can no longer be seen.
Walks follow people
A walk happens when someone has the time, which is rarely when the critical work happens.
Night and weekend work
Shifts outside office hours are the hardest to cover with a camera in someone’s hand.
Walks stay the best way to see a whole site in detail. A fixed station watches the zones where timing matters, so the record has no blank hours.
Continuous scans in SpatialSense
Every point, in 3D
Each scan is a full point cloud of the zone, so you can measure on it like any other scan.
One project, every source
Fixed scans sit with your walks, drone flights and issues, so nothing lives in a separate system.
Periodic walks and fixed LiDAR, side by side
They do different jobs, and most projects need both.
| Fixed LiDAR stations | Periodic walks | |
|---|---|---|
| How often | Every 15 to 30 minutes, around the clock. | When someone walks: daily, weekly or less. |
| Who captures | Nobody. The station runs on its own. | A person with a camera. |
| What it covers | The zone each station looks over, in full 3D. | The whole route, in 360° photos. |
| Best for | Critical zones where timing matters. | Seeing the whole site in detail. |
| Where it ends up | In SpatialSense, dated and placed. | In SpatialSense, dated and placed. |

Frequently asked questions
What is continuous LiDAR monitoring on a construction site?
Fixed LiDAR stations mounted around the site scan their zone on a schedule, with no operator. In SpatialSense each station produces a full point cloud every 15 to 30 minutes, day and night.
How is it different from a 360° site walk?
A walk covers the whole route in detail, at the moment someone walks it. A fixed station covers one zone, all the time. Most projects use walks for the whole site and stations for the zones where timing matters.
How long has it been running in practice?
Our longest-running installation, on a public works site in Hong Kong, has been scanning for more than two years.
Can I compare scans from different times?
Yes. Every scan is dated and placed, so you can open any two side by side, or measure the change between two point clouds.
How do I get started?
Book a demo and we look at your site together. The SpatialSense platform itself has a 30-day free trial with no card details, for your walks, drone flights and scans.
