ELEVATION CERTIFICATE uses???

It is what it is. A slab on grade, no crawl space, no basement, no stilts. Just do it like anything else but include in the notes section that there is nothing there on the date you were there except the slab on grade with no definite knowledge of what might be placed on it in the future. That's the truth.

Its a 1B, we do these all the time, unless they raised it with piers. If it is for pre a lot of times they do not know yet how high they want to raise it. in my neck of the woods, it is usually 3 feet or less they will bring in fill, more than 3 feet they use piers. Which would change it to a 5.

A bit of history. About 15 years ago I was contacted by a firm to survey out a small tract immediately adjacent to something like seven parallel petroleum pipelines in an easement from the 1930's. One unused pipeline was going to become the home of a major fiberoptic cable. They were going to install a facility to effectively step up the cable's power, or something like that. A number of boxlike structures full of electronics were to be installed.

We arrived at the site and noted it must be in the flood plain of the nearby river. We started our work as usual but upon return to the office checked the flood plain map. As I recall, ground level was on the order of 10 to 12 feet below the BFE. I called my contact and started asking a lot of questions, especially as to how well sealed these boxlike structures would be if underwater for a day or two or three. Somebody go their butt chewed and a new site about a half mile away and about 25 feet higher suddenly became the site that was in need of being surveyed.

First thing is you need to do, is get in writing the proposed elevation of the slab either by a letter, email statement or a copy of the plans from the owner, engineer or architect. Whatever documents are used, the proposed elevation needs to be stated on it. It can be as broad as the slab elev. will be at or above the BFE but use the actual number.

It's either a 1A or 1B depending on the type of construction and can be determined by the drawings. if no drawing are available get a statement as to the type of construction. Traditional slab on grade is a 1A, with a raised slab on stem wall a 1B. I do 2-4 EC's per week mostly on a slabs and have done 1 diagram 1B in the last 10 years.

My guess is a 1A. Go to the site and determine the HAG and LAG and fill in section C2 f and g. The proposed slab elevation, taken from the letter, goes in the comments section. Elevations in Section C2 is only for those elevations that can be determined, any proposed elevations goes in the comments section.

For C1 check off construction drawings.

This is for an engineering company that I do a lot of work for and I do have drawings without any elevations on them. This survey is probably because of the initial plan review and the results will be shown on revised plans, then we will prepare a certificate per the construction plans using our ground data.

You are signing/stamping an elevation certificate stating the top of slab elevation on the drawing is at a certain elevation, yet there are no elevations on them.

Think about that concept or better yet if something goes wrong think about an attorney asking that question in court.

I get the same request all the time. I send the drawings back and make them put the proposed elevation on the drawings and resend it to me. It is usually something like "minimum top of slab elevation is at 20". This would be where the BFE is at 20'

The existing elevation of the gravel inside the tower compound is 4' above BFE, it is an AE Zone.

What I was trying to say was that the engineering company would probably revise their plans per my survey and give me a set with elevations on them for me to use in completing the elevation certificate.

When in doubt attach notes.
My elevation certificates include one or more pages of attachments with images of the mechanicals, oddities and the justification of things when needed.
I also attach a FIRMette with locus circled in red.

I did my first 1B the other day. Concrete block outer retaining wall, filled with soil, then slab poured on that. Had a front porch which made it look like a pier and beam house. Brick veneer on the sides went all the way to the ground. You could only see the stem wall from just the right angle on the side of the porch. Looked really nice.
