Calculation:Material cost:

Cost / 100m21 coat primer = RM120 / 5 x 8.3 = RM199.20/100m22 undercoat = RM120 / 5 x 7.2 x 2 = RM345.60/100m21 final coat = RM 38 x 8.3 = RM315.40/100m2

Painter at RM88.00/day = RM88/8 = RM11.00 Unskilled labourer at RM52.50/day = RM52.50/8 = RM 6.56

RM17.56

Time required to paint 100m21 coat primer = 5.00 hr/100m22 undercoat = 4.4 x 2 = 8.80 hr/100m21 final coat = 3.40 hr/100m2

Total time required to paint 100m2 = 17.20 hr/100m2

Total labour cost = hourly rate x time required= RM 17.56 x 17.20 hr/100m2 = RM302.30/100m2

Total cost per 100m2 including profit and overhead:Material cost + Labour cost = RM946.22 + RM302.30 = RM1248.52/100m2Allow 20% for tools = RM1248.52 x 20% = RM 249.70/100m2

Gross total cost per 100m2 = RM1498.22/100m2

Add profit and overhead = RM1498.22 x 15% = RM 224.73/100m2Total cost per

100 m2 = RM1722.95/100m2

Unit cost:Total cost per 100m2 / 100m2 = RM1722.95 / 100m2 = RM17.23/m2

Calculate the cost per m2 for the 20mm thick cement and sand (1:3) plastering with approved plasticizer as described to wall and column.

DATA:

Materials:ITEM COST

Ordinary Portland Cement (50kg/bag) RM16.96/bagSand (Normal Mining Sand) RM37.81/m3

Shrinkage factor for (1:3) mix 30%Wastage factor for mixing mortar 10%

Labour rate:Skilled Labour RM85/day

Unskilled Labour RM63/day

Output data:- Plasticizer used is 6 litre/ton of cement at a cost of RM5.00/litre.- Coverage for 20mm thick plaster is 75m2 / 1000kg- Gang compromises 2 skilled & 1 unskilled labourers. Gang output for mix and apply is 100m2 in 18 hours.- Taking delivery & stacking cement at 20 nos of 50 kg bag per hour.

Material weight:- Density of cement is 1420 kg/m3- Density of sand is 1600 kg/m3

Tendering factor:- Allow 15% for profit and overhead.

* Cost of paint is obtained from Seng Bee Hardware & Timber Sdn Bhd, Mr. Lee

* Daily rate for plasterer is obtain from CIDB

Calculation :


Ordinary Portland Cement including unloading:1m3 at 1420kg/m3 at RM 16.96 / 50kg = 1420/50 x RM16.96 = 481.66

Sand at 3m3 at 1600kg/m3 at RM37.81/m3 = 37.81 x 3 = 113.43 Gross Total 595.09 /4m3

Divide by parts of mix (1:3) = 595.09 / 4 = 148.77Plasticizer 6L/1000kg cement @ RM5/litre = 6/1000x(1420/4)xRM5.00 = 10.65 159.42

Add shrinkage, waste (30% + 10%) = 159.42 x (30% + 10%) = 223.19

Cost per m2 = 223.19 x 0.020 = RM 4.46/m2

STEP 2: Labour costLabour Gang:- 2 skilled labour @ RM85/person/day =RM85/8 x 2 = 21.25/hour- 1 unskilled labour @ RM63/person/day =RM63/8 x 1 = 7.88/hour Labour gang hourly rate (RM) = 29.13/hr

Coverage of plaster is 75m2/1000kg =1000/75 =13.33kgAssumed 1000kg is refers to cement only

Time required by labour:Delivery and Staking of 13.33 kg cement = [13.33/(20 x 50)]x1 = 0.013 hrMix and apply 1m2 = 18 hr / 100m2 =0.180hr Total time required 0.193 hr

Total labour cost per m2 = 0.193 x 29.13 = 5.62/m2

Step 3: Total cost (m2)

Total cost : Material + Labour = 4.46 + 5.62 = RM10.08Add 15 % profit & overhead = RM 1.51 TOTAL RM 11.59

Calculate the cost to finish 20 mm thick cement and sand (1:3) screed including smooth steel trowelled as described to floor.

DATA

Material cost:- Ordinary Portland Cement 1m3 at 1420kg/m3 at RM16.96/50kg

- Sand 1600kg/m3 at RM37.81/tonne- Allow 33.33% waste and shrinkage for cement mortar

Labour cost:- Unskilled labour for cement mortar mix RM52.50/day(8 hrs)

Output data:- To mix 1m3 of cement mortar require 1 hour

* Dairy rate for general builder is obtain from CIDB

Calculation

Step 1: Material costCement mortar mix (1:3) - m2

Ordinary Portland Cement including unloading:1m3 at 1420kg/m3 at RM 16.96 / 50kg = 1420/50 x RM16.96 = 481.66

Sand at 3m3 at 1600kg/m3 at RM37.81/m3 = 37.81 x 3 = 113.43 Gross Total 595.09

Add shrinkage, waste etc 33.33% = 595.09 x 33% = 198.34 Net total for 4m3 793.43

Divide by parts of mix (1:3) =793.43/4 =198.36/m3

Total Material Cost/m2 =198.36 x 0.020 = 3.97

Step 2: Labour cost

To mix cement mortar @unskilled labour rm52.50/day = RM52.50/8 = 6.56/ hr @cost to mix 1m2 =RM6.25x1x0.020 = 0.13 / m2 Total labour cost / m2 0.13

Step 3: Total Cost (m2)Total cost = 18 (3.97 + 0.13) =73.80Add 15% for profit and overhead =11.07 84.87
