Hi i am new to this and need help determining what the finished floor elevation for this particular site and layout should be.

How to set finished floor elevation.

In rare exceptions we ll set a ffe for a lot if we re having difficulty with getting adequate fall to the sewer. The grading optimizer then knows to only grade at that elevation. To set a building at a predetermined ffe set the minimum and maximum z to the same elevation. Finished floor level ffl refers to the uppermost surface of a floor once construction has been completed but before any finishes have been applied.

There may be regulations you need to follow regarding keeping your finished floor above flood elevations. So in concrete construction it may be the uppermost surface of a screeded finish or in timber construction ffl will denote the top level of. That wall would be 16 feet 6 inches above the finish floor. If you think your flange is not set to the right height or it needs to be replaced then you ll want to do that right away.

We only set finished floor elevations on lots that have 100 year flood elevations encroaching on the lots. If user only set one and not the other z then that leave the optimizer to either grade. My first inclination is to go with a 394 elevation since that is the elevation the driveway will come in at. 6 inches above adjacent roadway crown perpendicular to property.

14 inches above lowest property drainage outfall point from site. How can i set the finished floor elevation of a building pad to a predetermined elevation. For example you may have masonry walls on the sides of the building showing top of wall at 16 feet 6 inches on the drawings. No it s not added.

An unlevel flange like already mentioned can make your toilet wobble or leak at the base. If the bm is 3 5 and the ff is to be at 7 0 you go to 7 0. So you need to be 3 5 above the bm. I assume you re saying the finished floor elevation needed is 7 foot.

The finish floor is then considered ff 0 0. For those that don t already know the proper toilet flange height is when it s flush with the finished floor.
