4. Life Cycle Cost Analysis: a) List the components of agency cost (3) b) List the components of the User Cost (3) c) For the following expenditure streamline, determine the PW value and the EUAC. Assume the initial construction performance period (design life) is 20 years. Estimate the LCCA for an analysis period of 15 years. Assume remaining life of initial construction based on number of years. Given discount factor of 4%.
