Browse Forums Building A New House 1 Jan 20, 2009 11:30 pm I have just been given my engineering drawings but am not sure what all of it means. I think I've deciphered the fall and the gradient (although I'm not sure what's a good gradient) but the numbers in circles are a big mystery to me and I'm not positive I've got the other stuff right either!
If anyone can interpret it all I'd be very grateful! This is my own drawing, the real file was too big to post. The only thing that isn't a faithful replication are the numbers on the right top corner, these were written in a slant towards our cut off corner (it's a corner block). Thanks! * NOTE* scroll down for picture a few posts down. Thanks! Building Emperor Q2 with Henley in Featherbrook stage 13, Point Cook. Slab laid - Building has begun! Re: Help reading my engineering drawing please - it's up now! 2Jan 21, 2009 7:37 am Hi Beebie,
Try uploading your drawing (original one) to photobucket or imageshack, then posting it here using the Img tags. http://imageshack.us/ http://photobucket.com/ Here is a thread you can follow: https://forum.homeone.com.au/viewtopic.php?t=1272 The original file shouldn't be too big to post if you choose a file size (once uploaded to hosting site) that is around 1000 pixels wide (roughly!) Hope that makes sense? Henley - Wilshire Mk 3 ... I love my house!!

You're like my own personal homeone guide and saviour these days!
I think I've done it so it'll come up below when I post this, if so, hopefully I'll get some answers now!

Re: Help reading my engineering drawing please - it's up now! 4Jan 21, 2009 10:05 am Basically it almost dead flat. the fall will not be an issue at all. Going by the figures you have given there is an enormous amount of fill. Up to 1.78m of fill. This will be very costly. The circles are pit numbers I think. Re: Help reading my engineering drawing please - it's up now! 6Jan 21, 2009 10:21 am Looks like there's a sewer easement at the back. The width of the easement should be marked on your plan of subdivision, it's usually 2 or 3 metres.
It does look like there's quite a bit of fill required - but the site costs may not too awful. Fill can mean a slab upgrade and/or piering is required to ensure there's minimal movement. If you get a soil compaction report from the developer after the subdivision construction work is complete, your builder may be able to reduce or do away with piering, or even downgrade the slab (maybe?) and reduce costs. On the plus side, a practically flat block is good... Re: Help reading my engineering drawing please - it's up now! 7Jan 21, 2009 10:23 am FS means finished surface...
The number adjacent is the natural surface level... There is a sewerage line at the back of the block, and hence an easment will be required... You won't be able to build with xxx mm of the line... Ch, refers to chainage... Which is a distance from a known piont... You're adjacent block will show a different ch number.... Make sure with 1.7m of fill you get a compaction certificate... Otherwise you'll have to put down bored piers of at least 2.2m depth, at 2.4m grid centres... Not cheap across the house pad!!! The circled numbers should refer to a lot number, and possibly a mainhole/access pit number.... Electrical Engineer... Don't hold that against me... And keen owner builder... Mainly the building part!! Re: Help reading my engineering drawing please - it's up now! 8Jan 21, 2009 10:32 am the circled numbers are not our lot number.
can someone tell me which numbers refer to fill? i don;t see where the 1.7 is coming from? Building Emperor Q2 with Henley in Featherbrook stage 13, Point Cook. Slab laid - Building has begun! Re: Help reading my engineering drawing please - it's up now! 9Jan 21, 2009 10:50 am ok, i've figured out the fill figures. thanks for all your help guys! It's great to have some more info.
Looking at all the blocks in our stage of our estate, they all have very similar amounts of fill, so at least I know I didn't get the dud block, they're all in the same boat - in fact ours is one of the flattest so we're on a winner there. We've allowed $15 for site costs but were obviously dreaming the good dream where we'd save money here - not so likely you'd say? but will it likely be more than this? I've emailed the devoped just now asking if they have the compaction report (I've been checking the local council's minutes - ahh the internet - and they should have done it already) and if i can have a copy. so hopefully I'll have even more info soon. Is it right to say that if the site is compacted well I still may get an H class slab but that M is out of the question? or am I way off base here?

Re: Help reading my engineering drawing please - it's up now! 10Jan 21, 2009 10:54 am If the natural surface level is 8.41, and the plan is to have a finished surface level of 10.14, the only way to achieve that is to add 1.73m of fill.
Simple maths. Just out of interest, Beebie - what are the dimensions of your block? Re: Help reading my engineering drawing please - it's up now! 11Jan 21, 2009 11:00 am It's impossible to say without soil tests what kind of foundations you'll need. It also depends on the size of your house, whether it's single or double storey, and possibly how your builder does things.
My block is as close to dead flat as you can get, but had almost 2m of fill in some places. No rock removal required, nothing in the way of earthworks, and a compaction report reduced the need for piering, but didn't eliminate it because we built very close to the sewer easement. Costs came in at over $12,000. We were originally counting on a maximum of $10,000, so that didn't make us happy. Oh well.... Re: Help reading my engineering drawing please - it's up now! 12Jan 21, 2009 11:14 am our block is 18m across and 32 deep.
The house we're planning to build is a double story, 38.5 squares. It has a small footprint, only 213.5square metres over 576square metres of land. Our plan is to set it as close to the southern (bottom) boundary as possible with a required 5.5m setback.

Re: Help reading my engineering drawing please - it's up now! 13Jan 21, 2009 1:12 pm A compaction report is the only way you'll get around piering for the house slab...
Hopefully the developer has given you one of these, otherwise... Ka Ching.... $$$$$ Electrical Engineer... Don't hold that against me... And keen owner builder... Mainly the building part!! Re: Help reading my engineering drawing please - it's up now! 14Jan 21, 2009 2:00 pm as I've said, I've asked for a report today. I don't get title until at least august, so i'm not sure if I can get it now or have to wait.
Is there a ballpark figure (estimate obviously) for "$$$"? Building Emperor Q2 with Henley in Featherbrook stage 13, Point Cook. Slab laid - Building has begun! Assuming you've modelled the TB8, TB10, TB12, TB2 & J1 joists/LVLs there, it appears as per drawing to me. There maybe should be an additional J1 between TB10 and T12 if… 3 31780 Thanks for all replies. I just noticed now the pictures I added to post right on top of page were wrong.
