English term

Grade level

English Tech/Engineering Construction / Civil Engineering construction of a nuclear plant
Before it was excavated, the site’s elevation was approximately 35 m, and the elevation at the top of the cliffs was approximately 30 m. Since TEPCO selected grade levels of 10 m for the block of Units 1 to 4 and 13 m for the Unit 5 and 6 block, significant excavation was required, as shown in Fig. 1.2–6. The reasons for selecting grade levels of 10 m and 13 m are described in the section on ‘Geology’ below and are further discussed in Technical Volume 2, Section 2.1.

Units refer to nuclear units

Note from asker:
Thanks everyone! Yes, I am asking a series of question about Fukushima accident back in 2011!
Peer comment(s):
agree Terry Richards : Yes, relative to sea level or some other arbitrary zero level. They had to dig down from 30/35m to 10/13m which is a lot of digging!

Thanks, I guess that's the idea

Thank you!
agree Didier Fourcot : Zero level on plans, understood as reference levels here. In "normal" buildings, is more or less related to the ground level before, here there is earth moving before construction, so this is the reference chosen for the finished ground level

Probably. Thanks!
agree Tony M : Given the location of the Fukushima plant, it looks as if this may indeed be ASL (above sea level) / Yes, Asker has been asking a whole series of questions about Fukushima.

Thanks. But we can't be sure of this location.

Thank you!
agree B D Finch : Note that you must distinguish between rough grade level and finished grade level. In EN-GB that would be "finished ground level". Levels are, as far as I'm aware, ALWAYS relative to the standardised sea level for the country in question.

Problems due to poor definitions of "grade level"

It appears that US definitions of grade level are not standardised in the same way as in the UK, which sets a datum point on site relative to ASL and all levels e.g. finished ground and floor levels and roof heights are measured from that datum point. The US method of measurement cited below ran into problems of developers cheating by earth-moving and had to be redefined according to this document.

'The Louisville Municipal Code (LMC) prescribes a maximum building height in all zone districts in the City. Section 17.08.045 of the LMC defines height as “the vertical distance measured from grade to the highest point on the roof surface.” Grade is defined in Section 17.08.205 of the LMC as “the average of the finished grade surface
elevation measured at the highest and lowest exterior corners of a structure.”'
