Question about locating retaining wall on plans

Question about locating retaining wall on plans

Question about locating retaining wall on plans

(OP)
Hi,

I have a question about specifying the location of a retaining wall on a set of plans.... when locating the wall on the site plan, would it be acceptable to locate the beginning of the wall by specifying the wall's station and offset based on an adjacent road's centerline?  Or is there a better way to do it?  Also, if the wall has a 12° batter... should the location point I'm specifying be based on the top, bottom, or centerline of the wall?

Thanks for your help.

RE: Question about locating retaining wall on plans

good questions never have good answers.

when i put a "designed by others" MSE sitewall on the grading plan, here's what i do.

1. use the bottom/face of wall for the line and note it on the plans.  If your site plan .dwg file is used for staking, this is most likely where they will start...at the bottom of the wall.
2. make sure the wall is located with enough buffer between site constraints (wetlands, easements, property lines, utilities, etc.) that it won't be the end of the world if they go with the top and the base moves out. if your client is a contractor/developer, they may independently choose to hold the top line to maximize usuable space at the top of the wall.

We would locate a work point and show coordinates.

RE: Question about locating retaining wall on plans

I would perfer a set of coordinates, But station & Offset is perfectly acceptable, assuming there is sufficent data to layout the road and the road will be layed out as part of the project. (I would not do station and offset if the only work was the retaining wall and you would have to layout an existing road to locate the wall)If location of either the bottom or top is critical, give the dimensions to that point. If not, I would locate the face of the wall at the footing and show the batter.
