Answer :
Let's solve the question step-by-step, considering the costs provided and calculating the subtotals and total project cost accordingly.
### Costs of Steel for the Head Frame
1. Steel Column
- Cost per unit: R500 per meter
- Quantity needed: Not provided (assumed to be 0 meters for this calculation)
- Cost estimate: R500 0 = R0
2. Steel for Cross Braces
- Cost per unit: R20 per meter
- Quantity needed: Not provided (assumed to be 0 meters for this calculation)
- Cost estimate: R20 0 = R0
[tex]\[ \begin{array}{|l|l|l|l|} \hline \text{Steel column} & R500 \text{ per meter} & 0 \text{ meters} & R0 \\ \hline \text{Steel for cross braces} & R20 \text{ per meter} & 0 \text{ meters} & R0 \\ \hline & & & \\ \hline & & & \\ \hline \text{Sub-total: Cost for steel frame} & & & R0 \\ \hline \end{array} \][/tex]
### Costs of Lift Components

- Cost: R150000
- Quantity needed: 1 (unit cost)
- Cost estimate: R150000
2. Winch and Motor
- Cost: R1200000
- Quantity needed: 1 (unit cost)
- Cost estimate: R1200000
3. Cable
- Cost per unit: R100 per meter
- Quantity needed: Not provided (assumed to be 0 meters for this calculation)
- Cost estimate: R100 * 0 = R0
4. Cage and Skip
- Cost: R350000
- Quantity needed: 1 (unit cost)
- Cost estimate: R350000
[tex]\[ \begin{array}{|l|l|l|l|} \hline \text{Sheave wheels} & R150000 & 1 & R150000 \\ \hline \text{Winch and motor} & R1200000 & 1 & R1200000 \\ \hline \text{Cable} & R100 \text{ per meter} & 0 \text{ meters} & R0 \\ \hline \text{Cage and skip} & R350000 & 1 & R350000 \\ \hline & & & \\ \hline \text{Sub-total: Cost of lift components} & & & R1700000 \\ \hline \end{array} \][/tex]
### Labour Costs
1. Project Manager
- Cost per unit: R30000 per month
- Quantity needed: 1 month
- Cost estimate: R30000 1 = R30000
2. Engineers
- Cost per unit: R30000 per month
- Quantity needed: Not provided (assumed to be 0 months for this calculation)
- Cost estimate: R30000 0 = R0
3. Artisans
- Cost per unit: R25000 per month
- Quantity needed: Not provided (assumed to be 0 months for this calculation)
- Cost estimate: R25000 0 = R0
4. Semi-Skilled Workers
- Cost per unit: R20000 per month
- Quantity needed: Not provided (assumed to be 0 months for this calculation)
- Cost estimate: R20000 0 = R0
5. Unskilled Workers
- Cost per unit: R12000 per month
- Quantity needed: Not provided (assumed to be 0 months for this calculation)
- Cost estimate: R12000 * 0 = R0
[tex]\[ \begin{array}{|l|l|l|l|} \hline \text{Project manager} & R30000 \text{ per month} & 1 \text{ month} & R30000 \\ \hline \text{Engineers} & R30000 \text{ per month} & 0 \text{ months} & R0 \\ \hline \text{Artisans} & R25000 \text{ per month} & 0 \text{ months} & R0 \\ \hline \text{Semi-skilled workers} & R20000 \text{ per month} & 0 \text{ months} & R0 \\ \hline \text{Unskilled workers} & R12000 \text{ per month} & 0 \text{ months} & R0 \\ \hline \text{Sub-total: Labour cost} & & & R30000 \\ \hline \end{array} \][/tex]
### Total Project Cost
Now, adding up all the subtotals:
- Sub-total: Cost for steel frame: R0
- Sub-total: Cost of lift components: R1700000
- Sub-total: Labour cost: R30000
TOTAL PROJECT COST: R1730000
[tex]\[ \begin{array}{|l|c|c|} \hline \text{TOTAL PROJECT COST:} & R1730000 & \\ \hline \end{array} \][/tex]
This completes the detailed breakdown and calculation of the total project cost.
