I interpreted it as having around max 500mm fall however a builder has told me it has 1400mm fall and would need a retaining wall so I will not be purchasing this block. Also I can tell the block has fill at the front does the FS39.58 mean 39.58mm if fill? What about CH 173.76, channel length of 173.76mm? What does the ES stand for? Does ES41.02 to ES40.50 mean 520mm fall? Thanks Re: Help reading an engineering plan 2Sep 29, 2020 6:56 pm Might be able to answer my own question ES is the existing surface, FS is the finished surface. ES41.02 top left corner of the block, FS39.58 bottom right corner of the block, therefore 1404mm of fall. Hopefully someone with more knowledge can verify this thanks. Re: Help reading an engineering plan 3Oct 04, 2020 5:46 am Hi Andrew , your interpretation is correct. Es- existing surface, fs-finished surface , difference between the two is the fill. Ch = chainage or distance in metres along the line - probably centreline of the road The r= will be radius of the kerbs Re: Help reading an engineering plan 4Oct 04, 2020 6:00 pm gavinpinksterboer Hi Andrew , your interpretation is correct.

Re: Help reading an engineering plan 6Oct 04, 2020 7:30 pm Guessing they've done that for drainage purposes? 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 31828 Thanks for all replies. I just noticed now the pictures I added to post right on top of page were wrong. I attached pictures showing "current" and my "suggested" floor… 9 14644 This is a very tight fit, I'm not sure if you'll be able to achieve what you've described. Would you consider accessing the separate toilet from the laundry? If so maybe… 1 11253 |
