A bridge will be maintained for a very long time. Each year the annual cleaning cost is A-annual. Every five year there is a big refresh (in addition to the annual) The cost is A-five year. Finally every 24 years there is a heavy duty refresh costing A-twenty four. What is the Capitalized Cost for this system? O Cap Cost = A-Annual* (PIA i 1) + A-five year *(PIA i 5) +A-twenty four *(PIAi 24) O Cap Cost = A-Annual/i + A-five year*(A|P i 5)/i +A-twenty four*(A|P i 24)/i O Cap Cost = A-Annual/i + A-five year *(A|Pi 5)/5*i + A-twenty four*(A|Pi 24)/24*i Cap Cost = A-Annual /i +A-five year *(P | AI % )/i +A-twenty four*(PIA I 24)/i O Cap Cost = A-Annual + A-five year/5 +A-twenty four/24
