As my house projects progresses before I cover things (walls, slabs etc..) I
would like to keep a record of where things are.

I already have a floor plan in a DGN file inside MicroStation that I am
working on, and all my framing plans are done that way.

Now that I have done some major relocation of drains etc...what is the best
way to add that detail into CAD?

I am thinking of just getting up to a high ladder and take a picture from
high up, then import the image into CAD, find two known points (room
corners) and scale/move the image to the right location in relation to the
my floor plan, and simply sketch in the drainsand electrical system, won't
be accurate but should be close enough for my use, beats measuring every end
of every pipe and elbows and fittings.

Is there an easier way?

It depends on your CAD package. I make drawings of
frequently-used components so I can bring them into plans.
(Libraries of the symbols and components you use may already be
available as add-ons for your CAD package). The "frequently-used"
part is important because I can draw the part once and re-use as
often as convenient.

I am using MicroStation. I don't mean the commonly used components like
fans, sink, WC, tub etc... those I have made cells (or ACAD blocks). I am
talking about the best way to draw in the "linework" for the drain lines or
electrical conduits. I don't plan on putting in the actual fittings and
elbows etc...for the drains.

I was going to measure off what the plumbers did when he reconfigured
everything, but now I think a photograph then reference it in to sketch over
seems to me the easiest way, if the photo can be taken with minimum
distortion.

If this might have some bearing on what you're looking for, I'd suggest
considering the free/libre Panotools suite that includes modules for
image-stitching; parallax, lense and perspective-distortion and
chromatic-aberration correction, and much more.
I've seen some very impressive results.
To start, I'd suggest the main wiki:

yes I am taking lots of picture on each stage of the project.

I think I have enough pictures that I can do a drill down - if I ever sell
this house I can set up a floor plan when the potential buyers look at a
room, then zoom in they see the tile on the floor, further zoom shows the
slab behind it, then the slab removed showing the compacted sand, then the
PVC drains...may freak people out lol.
