Barras, G C and Mayo, R E (1995) Minidirectional drilling for installation of underground electrical conduit. Journal of Construction Engineering and Management, 121(4), pp. 364-369. ISSN 0733-9364
Abstract
The Salt River Project (SRP), located in Phoenix, Ariz., uses two different construction techniques to install conduit for new underground electrical systems in the Phoenix metropolitan area: Open-trench cutting by conventional backhoes or wheel trenchers, and trenchless excavation techniques with minidirectional drilling machines and trenchless technology. This paper presents the results of research conducted to determine the comparative installation costs of conduit for SRP's underground electrical distribution, comparing the cost of conventional open trenching with minidirectional drilling. The study compared cost information that will aid SRP designers in optimizing the selection of site-specific underground electrical-conduit placement techniques. The research considered economies of scale, terrain, soil types, materials, and various common configurations of electrical conduit systems. In the years ahead, utility companies around the country may investigate the feasibility of minidirectional drilling to replace open trenching, especially in congested areas where the maintenance of good public relations is important. The analysis presented in this paper may provide a basis of comparison for other utility companies.

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
