A Forecasting Model for Rental Prices of Tower Cranes

摘要

In the Koran construction industry, the conventional methods to estimate tower crane rental prices are based on either standard unit prices or historical prices in previous contracts. These methods, however, have had problems not properly reflecting the level of tower crane rental demand. The present paper claims that rental prices are determined by the market prices affected by supply and demand mechanism rather than the two methods mentioned above. In this perspective, this study proposes a regression model by that construction contractors can assess appropriate rental prices of tower cranes considering both the factor of rental demands and adjusting factors. It specifically investigates the contracted prices of T-type 12-ton tower cranes which are the most common type of tower cranes in the field of apartment construction.
