Although parking revenue is a principal source of income, supply of parking
infrastructure at airports is based largely on expected needs. Although th
at is a rational basis, high investment costs and management fees are requi
ring developers and financiers to carefully analyze investment risks. This
paper focuses on sources of investment risk in airport parking infrastructu
re development and discusses the application of Monte Carlo simulation to e
stimate and understand the impacts of cash flow uncertainties on project fe
asibility. It is shown that cost overruns, which are common in construction
project development, have the most significant impact on return risk.
