Kan Chen CPCCBC4004A SID: 377108850 CPCCBC4004A Identify and Measure Material Quantities Written Assessment Task 1 11 Mar 2021 Project: Proposed House at West Hoxton Task: using the plan supplied of a typical slab on ground single storey brick veneer residential cottage, complete the questions below. This assessment is to be done using P10 quantity surveying paper. Question: Calculate the net (deduct openings) quantities required for each of the 3 categories below All answers are to include the appropriate measurement units, eg: m, m 2 etc 1. Brickwork * brick dimension 230x110x76; 50 bricks per square meter i. 110mm skins of face brickwork to the house 1. South elevation: height 2440-260=2180; width 5390; bedroom brick area=2.18x5.39=11.75m 2 ,extra area:width 2400, W5 area=1.78m 2 ,brick for extra area=2.4x2.18-1.78=3.45 m 2 , total south brick area = 11.75+3.45= 15.20m 2 2. North elevation: total area=7.79x2.18=16.98m 2 ; W2+W3+W4= 9.16m 2 , brick area = 16.98-9.16= 7.82 m 2 3. East elevation: width 8990; total area = 8.99 x 2.18=19.60m 2 ; W1=0.72m 2 ; brick area = 19.6-0.72= 18.88m 2 4. West elevation: width 4190+4800=8990, total area = 8.99x2.18=19.6m 2 , D2 area = 1.93m 2 , W6 area = 5.54m 2 , brick area = 19.6-1.93-5.54= 12.13m 2 5. Total area: 15.2+7.82+18.88+12.13 = 54.03m 2 ; taking 50 bricks/m 2 ; roughly need 54.03x50=2701 bricks 6. Extra 2 brick course for rebate edge beam: perimeter = (2x7790)+(2x8990)=33.56m, brick length 0.23/brick, therefore number required roughly = 33.56/0.23=146 bricks, 2 course ~ 292 bricks for rebate Page 3 of 6

Kan Chen CPCCBC4004A SID: 377108850 7. Total bricks for the house roughly: 2701 + 292 = 2993 bricks ii. 230mm solid brick wall to the carport 1. Carport wall length 5990, height same as house = 2440- 260=2180, wall area = 13.05m 2 , 50 bricks/m 2 therefore bricks required = 13.05x50=652 bricks; double brick ~ 1304 bricks 2. Concrete i. Concrete to the house slab only (exclude patio and concrete path) 1. Edge beam Rebate 160, slab thickness 100, house slab has 2 sections from south to north 2. Gross area = (7790-320)x(8990-320) = 64.76m 2 3. Deduct area = 2400x4800=11.52m 2 4. Total house slab area = 53.24m 2 5. Volume of concreate = 53.24 x 0.1= 5.323m 3 ii. Concrete to the house footing beams 1. Edge beam width 300, height for main edge beam 240; hight difference for edge beam and slab = 160-100=60; width difference for edge beam and rebate = 300-160 = 140. 2. Perimeter for edge beam = (7790x2)+(8990x2) = 33.56m 3. Area edge beam major = 300 x 240 = 0.072m 2 4. Area edge beam minor = 60 x 140 = 0.0084m 2 5. Total edge beam area = 0.0804m 2 6. Volume of edge beam = 0.0804 x 33.56 = 2.79m 3 iii. Concrete to the carport slab 1. Carport length 5990, width 3350, double brick rebate on 1 side only 230, thickness 100, carport area = 5990 x (3350) = 20.07m 2 2. Volume of concreate for carport slab = 20.07 x 0.1 = 2.007m 3 iv. Concrete to the carport footing 1. Footing only for the double brick rebate on 1 side of wall, width 300, height 400, length 5990 2. Volume of concrete for carport footing = 300x400x5990 = 0.719m 3 v. Concrete to the Patio 1. Patio area length 1500, width 1170, step down 150 to concrete path, patio thickness 250, concrete path thickness 100 2. Patio Gross Area= 1500 x 1170 = 1.755m 2 3. Patio Gross Volume = 1.755 x 250 = 0.438m 3 4. Concreate path area = 1170 x 2650 = 3.1m 2 5. Concreate Path Volume = 3.1x0.1 = 0.31m 3 6. Concreate to Patio and path = 0.438+0.31 = 0.748m 3 Page 4 of 6
Kan Chen CPCCBC4004A SID: 377108850 3. Reinforcement i. SL72 Reinforcing Mesh * area of SL72 is 6x2.4=14.4m 2 , Used in house slab, carport slab, patio slab (overlap 150 at step down), concrete path slab. 1. Concreate path slab area = 1170 x 2650 = 3.1m 2 2. Based on calculations from above total area = House slab (53.25 m 2 ) + carport slab (20.07 m 2 ) + patio area (1.755 m 2 ) + stepdown overlap area (150x2x1170) + concreate path (3.1 m 2 ) = 78.21m 2 3. Number of SL72 mesh needed = 78.21/14.4=5.36 or 6 mesh ii. N16 Reinforcing bars * assume bar length 6m, used in footings of house edge beam (3 bottom), carport wall edge beam (top and bottom 3 each), the gap left is 50, NO OVERLAPS 1. Perimeter of house = (7790-100)x2+(8990-100)x2 = 33.16m 2. N16 bars required = 3 x (33.16/6) =16.58 or 17 3. Length of carport wall edge beam 5990-100 = 5.89m 4. N16 bars required = 6 x (5.89/6) = 5.89 or 6 iii. How many stirrups *stirrups assume R6 at 500 cts, assume 1 stirrup is used every 500 for both bottom bars only as well as top & bottom bars. 1. Stirrup For perimeter of house edge beam from above = 33.16/0.5 = 66.32 or 67 2. Stirrup for carport edge beam from above = 5.89/0.5 = 11.8 or 12 Page 5 of 6
