2. Go to unit 9 and download the wall-to-floor ratio ppt Read through the ppt and complete the task for building B Name your file wall to floor ratio and Submit your ppt tomoodle unit 9 under the link Submit wall floor ration ppthere 3. Wall-to-floor ratiosThe following activity asks you to look at the wall-to-floor ratios and form afinancial comparison between two designs. The smaller the ratio the more floorspace is created which in financial terms for a client would be rentable areas.Building APlan area = 35m x 35mHeight = 35mStorey height = 3.5mBuilding BPlan area = 22.5m x 22.5mHeight = 24.75mStorey height = 2.75mIf the floor budget construction cost is 50/m2 and the wall area construction cost 25/m2,calculate the wall to floor ratio for both buildings. 4. Find : The Wall-to-floor ratios Worked example Building A Number of floors = 35/3.5 = 10 floors Total floor area = 10 x 35 x 35 = 12,250m2 Total wall area = 35 x 4 x 35 = 4900m2 Total wall cost = 4900 x 25/m2 = 122,500 Total floor cost = 12,250 x 50/ m2 = 612,500 Wall/floor ratio = 122,500 = 0.20 Building B Number of floors = 24.75/2.75 = ? floors Total floor area = 9 x 22.5 x 22.5 = ? m2 Total wall area= 24.75 x 4 x 22.5 = ? m2 Total wall cost = 1114 x 25/m2 = ? Total floor cost= 4556 x 50/m2 = ? Wall/floor ratio= ? = What amount a decinal
