Proposed answers to lesson 2 calculations

Walls – 13mm Aqualine,fixed to timber, stopped to level 4 (m2) Materials - 13mm Aqualine (1.20 x 2.70) = $ /3.24 = $15.00 /m delivery= $16.00/m2 x 10 % wastage = $17.60/m2 Labour (as before) = $11.50/m2 TOTAL =$29.10/m2

Walls – 10mm Standard above 3.0m high,fixed to metal battens, stopped to level 4 (m2) Materials - 10mm standard (1.20 x 2.40) = $35.00 $35/2.88= $5.73 /m delivery= $6.73/m2 x 10 % wastage = $7.40/m2 Labour – fixing ($6.50 on the ceiling) + stopping $6.00 = $12.50/m2 TOTAL =$19.90/m2

Walls – 2 layers of fryeline, fixed to timber, stopped to level 3 (m2) Materials - 16mm Fyreline (1.20 x 2.40) = $53.00 $53.00/2.88= $18.40 /m delivery= $19.40/m2 x 10 % wastage = $21.34/m2 for 1 layer 2 x layers = $42.68/m2 Labour – fixing ($9.50 on the walls for 1 layer) + stopping $3.00 = $9.50 x 2 + $3.00/m2 = $25.00/m2 TOTAL =$67.68/m2

Fire sealant (m) Materials – 3.00/m Labour – 2.00/m TOTAL = $5.00/m2

Square stopping (m) Labour only item– $6.00/m TOTAL = $6.00/m2

75mm Classic Coving (m) Materials – 3.00/m x 10 % wastage = $3.30/m Labour – fixing $5.00 TOTAL =$8.30/m

Walls – 1 layer 10mm noiseline, 1 layer 13mm noiseline both sides, fixed to steel, stopped to level 4 (m2) Materials - 10mm noiseline (1.20 x 2.40) = $23.00 $23.00/2.88= $7.98 /m delivery= $8.98/m2 x 10 % wastage = $9.87/m2 for 1 layer 13mm noiseline (1.20 x 3.0) = $34.00 $34.00/3.60= $9.44/m delivery= $10.44/m2 x 10 % wastage = $11.48/m2 for 1 layer

Walls – 1 layer 10mm noiseline, 1 layer 13mm noiseline both sides, fixed to steel, stopped to level 4 (m2) For one side of the wall 10mm noiseline + 13mm noiseline = $ $11.48 =$ 21.35/m2 For both sides of the wall = $21.35 x 2 = $42.79/m2

Walls – 1 layer 10mm noiseline, 1 layer 13mm noiseline both sides, fixed to steel, stopped to level 4 (m2) Labour For one side of the wall Fixing (2 x $5.50 (on the stack) + stopping $6.00 = $17.00/m2 For both sides of the wall $17.00 x 2 = $34.00

Walls – 1 layer 10mm noiseline, 1 layer 13mm noiseline both sides, fixed to steel, stopped to level 4 (m2) Total materials and labour = $ $34.00 = 76.79/m2

Sound sealant (m) Materials – 3.00/m Labour – 2.00/m TOTAL = $5.00/m2

Bulkhead – 13mm standard, fixed to timber, stopped to level 4 – 300mm wide(m) Materials - 13mm standard = $ delivery= $7.00/m2 x 10 % wastage = $7.70/m2 Each side only requires 300mm wide $7.70 x.300 x 2 =$4.62/m

Bulkhead – 13mm standard, fixed to timber, stopped to level 4 – 300mm wide(m) Labour- calculation for fixing is $5.50 x.30 x 2 = $3.30/m Stopping $6.00 x.3 x 2 = $3.60/m Total labour = $6.90/m

Bulkhead – 13mm standard, fixed to timber, stopped to level 4 – 300mm wide(m) Total materials + Labour = +$4.62+$6.90 = $11.52/m Is that right???? ( wastage on materials, labour rates – more difficult) What about square stopping and external angles – where are they measured - check
