Abstract

A conceptual cost estimate for a proposed facility is obtained with the briefest information. The simple method of estimating used in the industry results in an initial estimate that differs substantially from the final cost. The problem is more acute for innovative infrastructure projects because of the variety and non-repetitive nature of the projects. This study aims to address the challenge by proposing a cost estimating procedure based on system modelling and case-based reasoning. The effort is directed towards modelling the design solution that satisfies project requirements, and deriving the cost estimate based on comparison of the system model with previous solutions successively. Cases are proposed to be organized by formal concept analysis (FCA) and system modeling language (SYSML). Complementing the case structure, new retrieval and cost estimating algorithms are proposed. A case study has been conducted to illustrate how the model procedure works to get a validated accurate estimate.

Descriptive scope: 4 PCTE

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
