Abstract:Purpose
The current estimation practice in construction projects greatly needs upgrading, as there has been no improvement in the cost overrun issue over the past 70 years. The purpose of this research was to develop a new multiple regression analysis (MRA)-based model to forecast the final cost of road projects at the pre-design stage using data from 43 projects in New Zealand (NZ).
Design/methodology/approach
The research used the case study of 43 completed road projects in NZ. Document analysis was conduc… Show more
