Boat Dock
My party chief and I were sent to a new job yesterday. We have to topo a site for a new boat dock. There is an existing boat dock at the same location. The boat dock is located on a lake. We also have to stake out the new boat dock site. Only two points fall along the shoreline, the other points fall in the lake. How do you set the points that fall in the lake?

How deep is the water?
What kind of accuracy are you looking for?
I hope everyone has a great day; I know I will! -
pvc pipe

Maybe you are supposed to set tacks atop hubs that are long enough to stay above water level.:-S:-S:-S:-S:-S

Can you get them to drain the lake…:-S:-S:-S

set offsets… like 2 or three in line… project the line to the true point.
do you need a picture? -
I was thinking the same thing last night. Would be good for the construction company. No picture necessary, thanks!

Haven’t started the topo yet, have no idea how deep the water is. Think it would be a good idea to set 6′ PVC pipes if possible. I assume the accuracy wouldn’t be of paramount importance. It is the only boat dock in the area, exclusively for the use of residents. My common sense tells me to set points that will be useful to the construction company.

Too bad the construction company can’t be out there to tell us what would work best for them.

In our job folder there’s a parcel sketched on the plat, which defines the limits of the boat dock. I assume each parcel corner requires us to set one of our IPCs. How does a surveyor address the issue of setting a corner in a lake? I don’t believe our job scope requires us to stake out the actual boat dock. I apologize if I gave that impression.

It would probably be worth contacting them is possible to discuss what would be most helpful to them.

I am a fan of floating piers.

Field Dog: this is exactly the same as every other survey project. exactly the same…
somebody contracted for your work. ask them
somebody put that plan in your job folder. ask them
somebody is the consumer and would be using the stakes you set. ask themTALK to ALL of them. (written is better than verbal, less he said/she said noise later)

When I did construction staking it was SOP to ask the contractor what he needs.

Simple, wait till the lake freezes over then set the points in the ice.
Actually this is how it is sometimes done in the Adirondacks. That way they can bring out the material over the ice and set the piers. Come back after the ice is out and build the dock 😀 -
We’ve staked out sewer easements through water before, and we used threaded metal conduit. It came in 10′ sections, so we cut as needed, sometimes needing to screw in another piece, depending on how soft the bed was.

How did they build the sewer through the water

Caissons

Do just what Peter Ehlert suggested.
If the dock builders can’t figure out how to use triple offsets they shouldn’t be building docks anyway.
Which lake are you in? We have several projects with lakefront lots (Johns Lake and Lake Hancock) that are non spring fed and there is no way that we are going to set “poles” in the water. The non spring fed lakes in Central Florida have about 2 feet of bottom muck per foot of water. It ain’t no fun trying to maneuver in muck and water, been there and won’t do it again!B-)

Lake Willamie.
