A generic cost-concern matrix for identifying automation needs in construction
Automation in Construction 5 (2) (1996) pp. 91-104
The purpose of this paper is to present a framework for identifying construction automation needs. The generic framework was developed and demonstrated based on an example rapid transit system project. Forty-two generic construction tasks were generated to provide a break down of all the construction activities to the task level. An enhanced Cost-Concern matrix was proposed for identifying automation needs based on the gneric task level. Combining the productivity data of each task with the cost data yields the Cost Impact of the enhanced Cost-Concern matrix. An Automation Concern Index (ACI) was developed to incorporate the judgments of foremen concerning the motivations of automation. Tasks with high Cost Impact and high ACI are identified as potential automation needs. The results showed that Tie/Weld rebar, Arrange rebar and Position parapet segment are the most needs for automation. Future automation research and development can focus on the findings of this study to create effective achievement in automation development. For different types of construction, this framework and approach can provide guidelines and recommendations for identifying automation needs.
