El-Kelesh, A M; Heniegal, A M and Arnaout, M M (2025) Relative impact of factors affecting penetration rate of horizontal directional drilling. International Journal of Construction Management, 25(13), pp. 1501-1515. ISSN 1562-3599
Abstract
Prediction of the penetration rate (PR) of horizontal directional drilling (HDD) depends almost entirely on the experience of practitioners. This has resulted in actual values of PR that are inconsistent with the predicted ones. The problem stems from the many factors that are involved in the process and the need to assess their relative importance. To determine the factors that significantly affect PR and their relative importance, semi-structured interviews were conducted with HDD experts and a questionnaire was sent to other experts worldwide. The obtained responses are presented and discussed in the current paper. It has been found that ten factors significantly affect PR. The highest three factors are 'ground type and condition', 'geotechnical investigation', and 'operator experience'. The two factors 'geotechnical investigation' and 'steering engineer experience' which are newly introduced in this study are ranked as the 2nd and 5th most important, respectively. The interrelationships between factors are also discussed. The obtained findings show reasonably good comparison with observations of actual HDD works. On the basis of Pareto analysis made on the obtained responses, it has been found that the top 10 factors represent 72% of the effect on PR. In addition, implications for actual HDD works are presented.

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
