Some pictures from past months.
Bringing all Arcadis-Belgium surveyors together for a day of training. Each one prepared a presentation, during the morning we discussed the new Cadastral regulations in Belgium, learned about plotter settings, paper spaces, the online boundary research and our field software.
After lunch we went out in the field to train what we learned about cogo with our field software. 
A view while doing an as-built survey for one of the finished sewage projects.
Staking lots in a new subdivision with tiny lots.
I did a small monitoring job during the foundation works for a wind turbine in the port of Genk. 3 measurements a day during a week to check if the quay was moving.
At the other side of the canal was a scrap metal company, there was a serious blast during the pressing of the metal when I took this picture.
Christof.
With the blast that close to you, I'm surprised you were able to hold the camera steady. Was that part of normal operations or was it an accident?
What is the small prism? Is it screwed in the ground?
Here is what I use for deformation work when the points are flush with the surface (usually a punch mark in a brass bolt):
It has several advantages:
1) very quick to setup, typically less than 20 seconds
2) constant HI (10 cm)
3) it has a sensitive bubble, and because it is so low, any error in the bubble has minimal effect on the centering
4) very easy to carry around
It's the miniprism, part of this setup
but mounted in a frame, (I guess the plumb bob frame - but never used it that way)
I had to shoot 10 points per session, and each time from the same direction due to construction traffic. The only free line of sight at all times was along the quay.
Using the little frame on the concrete worked very fast for positioning the prism at the marker.
@ John: was an accident, but didn't harm anyone or anything, just a big bang and everyone continued working.

Those cooling towers in the last picture look like those used in Nuclear plants, but not quite as large as others I have seen.
B-)

What is a quay?
How much did it move ( in US survey feet please ) ?
😉

I love Google.

Bueno. Pronounced, "gooood." Si?
Christ-
Wish I could follow you about in your varied measuring exploits.
Great to see a Professional Measurer that is a top notch Professional Surveyor too !
Thank you for your continuing communications.
Cheers,
Derek
Pronounced like key, I think.
> Pronounced like key, I think.
Quai is a French word. Quay must be its Belgium equivalent.
Pronounced like Kay actually. Think Steppenwolf's lead singer John Kay. Or you can think gay, and replace the "g"; whatever trick works best 😉
According to Merriam Webster key, Kay and kway are all correct.
Origin:
alteration of earlier key, from Middle English, from Middle French dialect (Picard) kay, probably of Celtic origin; akin to Breton kae hedge, enclosure; akin to Old English hecg hedge
First Known Use: circa 1635
Now that's as clear as mud.
Great pictures, thank you. I wouldn't leave instrument cases open in Belgium weather...a little on the wet side, this country of a thousand beers.
Not to nitpick, but I noticed that you have the back of the bracket lined up with your scribed mark. Ok if you set the scribes the same way, or if you have your offset accounted for, but the zero offset to those brackets is the rearmost plumb bob slot.
There was another post regarding this not long ago. Be careful out there!
On the Quai at Smyrna
That's absolutely true,
you have to know the tools you're working with.
You must refer to this post about [msg=244572]the mini prism[/msg]

@Brad
the movement ... ah that's an easy one, even in US Survey feet.
0 mm must be 0 US Survey feet.
The quay (in blue) is anchored into the soil (red lines) under a certain slope.
The new foundation piles for the wind turbine had to be drilled in between these anchors, touching or damaging the anchors would result in mouvements of the quay ... and should have halted the drilling.
The anchors were previously surveyed at the quay and located with a probe (magnetometer cone) at the wind turbine location. Free space for the poles was 900mm with a Ø600mm for the poles, that leaves little margin of 150 mm (0.49 Survey Feet) at both sides for errors.
