Last week I did stake all the lots in the 'Bouvekerke' subdivision in Kortrijk.
It was the first time I could stake all lots in a subdivision in a single session, well it took me a little more then 2 days to stake and place 170 corners and some 50 nails in the gutter.
These Feno-poles weight a lot, you can only carry 10 to 12 of them in a bag ... my arms feels a little longer now then before the job! But they are placed easily.

Preparing the poles

and enjoying the sunrise on a foggy morning

the scenery


The markers line up fine.


I had to check the laser beam in the foggy conditions,
the picture does not do justice to the real sharp view.

Later on I drove to Ostend te remove and restake a pole, the city does not aprove the clients building permit, so the client wants his lot changed.

The only way to remove a the Feno-pole is by digging it out.


Christof.

Thanks for shareing. It is always interesting to see how others work.

Around here they remove pins with bulldozers and backhoes, while we aren't looking.

Beautiful shots of the job. Thanks.

Those Feno-poles are interesting. I'm guessing that you paid £6.95± (11.24 US Dollars) per unit? If you are planting 50 or more that is going to add up to a bunch.

Christ-

TU for showing me something I have never seen before.

Looking here: http://www.surveyingequipment.com/category/feno-markers/

I see them in their variety but don't understand how to set them.

It looks as though there is a mechanical operation that splays out the smaller rod sections.

When you have a moment can you explain how these Fenos are set and used please ?

Cheers,

Derek

PS-

We can ship you some more fog if you are short ! 😉

I always enjoy these posts. Setting those feno posts must be a two stage process, with the last stage being to bring out the claws. How does that work? edit. . like Derek just said.

Thanks,
Peter

Seems strange they would sell them at 13.77 inches and 23.62 inches long instead of 18+, 24+, or 30+ inches inches, to be technically compliant in those jurisdictions that require those minimum lengths. Even though this is vastly better than a rerod.

On re-reading the page, the figure gives slightly longer length that is a conversion from 24.0" - maybe they have addressed the issue, or maybe somebody just did sloppy metric conversions?

Derek,
jeff's link a little higher show the principle

I found some old videos from another job.

preparing the poles with the locking sleeve
Step1

then the actual placing of the poles is easy, First you drive the bar into the ground
second step is to use the sleeve to drive the 3 anchors in the soil to tighten the fixation
Step2

@ Bill
we pay 8€, that makes 11$ today, they come in boxes of 50 pieces.

john, i'll mail you some plans so you can see the progress.

Chr.
