Started with Maths today,Started with working out the area of foundations and the volume.For example,We used our Build measurements,7.200x15.500x.125(being the depth)=13.95m3,Thats the volume,The area is 15.500x7.200=111.600m2.Mark also showed us how to work out the required amount of joists we needed.Yet again we related this exercise to the build,So 15.500 divide by 450mm,(450mm being the distance between each joist.)which = 34.4,round up to 35,then add one more for the one for nothing making it 36 joists required.We then moved on to the working out of center of bearers,which is 7.200-.100=7.100,then 7.100 divide by 3 = 2.367mm,The next important thing I learnt was to calculate how many boards for the floor,To do this we need to calculate the area of the house,in this case,7.200 x 15.500=111.6m2,next up we need to get the area of the sheets of flooring we are using,the sheets are 3.6m x 1.2m=4.32m2,now all we do is divide the area of the house by the area of the sheet,111.6m2divide 4.32m2 =25.8 sheets,round to 26.so 26 sheets of partical board is needed.

(Flooring)To work out the amount of particle board needed.

After our maths session we switched around and went back to the build.Bracing was installed today to ensure our bearers we level.The first bearer we done,was taken down and new piles were cut in the correct lengths.This was after I used the builders level to gain the spot levels at each point.
