Manley Osbak, Vice President of Engineering & Estimating at The Crossing Company, will be presenting a paper titled "Investigation of Horizontal Directional Drilling Construction Risks" at the 2012 NASTT's No-Dig Show from March 11-15th, in Nashville Tennessee.

This paper is the first of its kind for the Horizontal Directional Drilling sector and we hope you are able to join us for this presenation as well as the very worthwhile No Dig Show. I have included the abstract for the paper as well as a link to the website below.

ABSTRACT: The risks associated with horizontal directional drilling (HDD) can have a significant impact on project schedule and cost. The potential disparity between tendered or budgeted cost and final cost are a source of concern for the industry. All of the parties involved share a desire to decrease the uncertainty associated with the final cost of an HDD project. However, the methods that may be employed to decrease this uncertainty come at a cost themselves. Since these methods generally only serve to decrease risk without necessarily eliminating it, there is a degree of uncertainty concerning the effectiveness of dollars spent on risk mitigation. Thus, Owners may be reluctant to spend budget funds on decreasing risk without sufficient assurance as to the value of such expenditures. There is a deficit of industry literature that can be used to assist in enumerating risks, the probability of occurrence and the impact of risk in quantitative terms. For much of the HDD industry, the assessment and valuation of risk mitigation can only be estimated and communicated using qualitative methods, which may be insufficient to demonstrate the value of risk mitigation. This paper discloses the risk events that have occurred on 100 medium and large HDD projects, the frequency of occurrence and the average schedule impact and Risk Factor of each event type. This work provides a body of information that can be used to quantify the probability of occurrence and the probable impact of a risk event. Which can feed into an estimate of the potential cost of a risk event, and in turn, to evaluate and justify the cost of risk mitigation.
