Initial Task Selection for Detailed Robotic Evaluation

Abstract

This paper provides a methodology for pre-selecting a limited number of activities for detailed investigation using existing robotic feasibility analysis techniques, such as that proposed by Kangari & Halpin [1]. The QCF Delphi method has been employed to survey a significant portion of a company's site management, in order to determine their views on the value of specific robotic or automated systems and to discover the reasons for these views. Using this method reinforcement cage fabrication, site stock control, concrete floor finishing and HVAC installation were found to be the preferred activities for robotic development. It was also shown that service installation and all forms of finishes are presently major sources of construction delay. The method also highlighted the importance of co-ordinating site activities and of controlling the design and management process in order to successfully exploit any automated or robotic system.

Automation Needs Determination Using AHP Approach

“…Basford and Askew [ 1 ] have identified automation Opportunities on a wide range of construction processes. Their subjects range from the task level up to a whole construction division.…”

Optimization of Service Routes in a Restricted Environment

“…In a multiround Delphi [5] study, 120 of the company's site managers were questioned about general site activities and their associated problems; the problems and benefits of robotic systems in construction; and the preferred activities for robotization. It was subsequently determined that service layout and design was an activity that causes particular problems on site [6]. The 4 major reasons for this were:…”

“…Consequently, whilst there is considerable recognition, by both the survey participants and the industry in general [1,2,6,7] that this activity is a key cause of delay, there is considerable doubt that this activity could be automated without first improving the management and control of its design [6,8].…”
