Need quick help from Architect/Engineer on commercial drawings

[sxtasy]

I am used to residential drawings in imperial measurements and I don't understand the graph/drawing in the bottom left of this document: http://saanich.ca/webapp/vso/display...=q10909_03.pdf

Anyone want to help? Thanks!

Do you mean the wall profile on the top left of the drawing if you look at it the right way?

If you're in Victoria before Friday give me a call, I'll sort it out for you.

Yes, that is what I am referring to ("Top of Wall Profile"). I know this is fairly basic, I just need a couple of pointers to help me decipher this. Thanks.

I am all over the place, Salt Spring Island, up island and Victoria. This tender is due on Monday, so time is of the essence
I am hoping to get this done tomorrow. I already have a good idea on price, this is the only part of the estimate I am not quite understanding

From what I can read on the graph, the 0+ 00.000, 0+05.00 etc is the length of the wall. So 0+05.00 is the 5 meter mark of the wall and the number right below it is the elevation at that mark. By elevation, it's usually in reference to something like sea level. In this case, for example (assuming it's from Vancouver Island) the elevation markers show this project at approximately 55-56 +/- meters above sea level.

That seems needlessly complicated...

Ok, thanks. The elevations were throwing me off, because this wall has an average height of 1.5 meters

haha, I know, welcome to city contracts...

1.5 meters sounds about right if you count the portion of the wall below grade. Good luck with the tender.

thanks frozenrice. I have never used sea level as a building reference before.

What about the tide, thats got to be +/- at least 1 meter lol.
Anyways, I've got to stop surfing beyond and get back to this dam estimate lol.

[lilmira]

0 or 100,000 is usually at grade. There's got to be a bench mark or two somewhere for construction.

Sta - station in metres
Elev- well, elevation in metres

It looks like you have over a metre of fill.

It looks like the elevations reference mean Sea Level but are usually denoted ASL but that does not mean they have not taken some random local datum.

^^^both comments are correct. I was just using sea level as an example. Now that I think about it the word benchmark rings a bell - couldn't think of the term yesterday.
