A city plans to upgrade its storm water management infrastructure by installing new pipes. The installation costs 2.1 million dollars and the annual maintenance cost is $28,000. Every 10 years, the system needs to be fully examined which requires a fixed management and material cost of $ 20,000 and a variable labor cost at the rate of $25/hr. 8 full time (working 8 hours per day) workers will be employed for 40 days for this task. If the infrastructure has a life time of 120 years and the city's interest rate is 8%
What is the capitalized worth of the project (in millions)? Please note that the value could be negative.
Answer: | Calculation of capitalised worth: | ||||
Present value | |||||
Particulars | Amount | Calculation | Amount | ||
Installation costs | 2,100,000.00 | - | 2,100,000.00 | ||
Annual maintenance cost | 28,000.00 | 28,000 / 0.08 | 350,000.00 | ||
Fixed management cost every 10 years | 20,000.00 | 20,000 * A/F(8%,10) | |||
20,000 * 0.06903 | 1,380.60 | ||||
Variable labour cost every 10 years | 8,000.00 | 8,000 * A/F(8%,10) | |||
8,000 * 0.06903 | 552.24 | ||||
Capitalised worth | equals | (2,451,932.84) | |||
