Day 70 - Numbers again (updated)

Post recovered by Loan! Many thanks, Loan!!

Concrete was poured yesterday. 68 cubic metres.

So... the permanent weight of this building (excluding temporary bracing) so far...
* 193 tonnes of crushed stone (drainage under footings and basement slab)
* 68 cubic meters of concrete @ 2.37 tonnes / m^3, for a total of 398 tonnes.

Cured concrete weighs 148 lbs per cubic ft, which is 3,996 pds per cubic yd -- about 2 tons (a ton usually means a "short ton", or 2,000 pounds). In metric, 1 cubic meter is 1.30795062 cubic yards (according to Google). This means 1 cubic meter weighs 2.37 tonnes (1 tonne = 1000 kg). For more details, check here.

For the moment, I exclude the weight of the foam and webs, wood to build frames around doors and windows, and the rebar. Off all of the parts excluded. the rebar is the bit that has any significant mass. There is very little wood and styrofoam has very little mass.

So.. the total of crushed stone and concrete is 193 + 398 = 591 tonnes. So the permanent part of the building weighs 1.3 million pounds (with the above exclusions). I guess you could argue that the crushed stone is not part of the building, although I include it as it is required to give proper support and drainage to the structure.

Looking forward...
Weather... poured rain all day today, more forecast for tomorrow.
Next steps... strip the WASS, add more crushed stone to level basement floor, lift the structural steel into place (not yet arrived) and install the Hambro floor joists.
