Fisher, D J; O'Neill, M W and Contreras, J C (1995) DS^2: Drilled shaft decision support system. Journal of Construction Engineering and Management, 121(1), pp. 86-94. ISSN 0733-9364
Abstract
Due to many uncontrollable and often unpredictable factors such as groundwater inflow rate, equipment availability and cost, weather, and various geological details, drilled shaft construction can become highly complex. At present, decisions on how best to install drilled shafts are made by foundation subcontractors, who have most often become experts in construction in local conditions. Unfortunately, the assistance of these field experts is not always easily obtained. Thus, a decision support system called "DS^2" has been developed to assist in the construction of drilled shafts. If used correctly, DS^2 can reduce construction costs by providing a large quantity of expert advice that would otherwise be both difficult and very expensive to obtain. DS-2 is composed of three prototype expert systems that interface with spreadsheet, database, and graphics packages. DS Z uses a heuristic, rule-based, backward-chaining system to analyze geological information, suggest a construction method, prepare a preliminary cost estimate, and suggest key specification items.

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
