Abstract
Tunnels are considered special structures because of their uniqueness in analysis, design, and construction. During the construction of the tunnels, it is desirable to optimise the lining formwork system for the rapidity with quality, safety, and economy. The requirement of the tunnel leads to the change in the structure of the lining formwork system. However, the selection of lining formwork system is comprehensive and requires years of experience. This necessitates the development of a novel framework to select a lining formwork system for tunnelling projects. Therefore, this study attempts to develop a framework for selecting a lining formwork system using the Delphi method. For this purpose, guidelines of the Delphi Method are modified to select the experts based on their qualifications and experience. Then, ten experts are elected as a panellist. Subsequently, a total of 11 factors and 43 sub-factors are identified from the existing literature. Out of these, eight factors with their sub-factors are shortlisted using the Delphi method. Afterwards, Cronbach’s alpha is determined for the remaining eight factors to test reliability. The proposed framework can help practising engineers to select and optimise the lining formwork system.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
