Topics investigated include: typical company profiles bidding and estimating practices types of projects conducted productivity and possible areas of future research.Īn analysis of the survey results revealed that 60% of contractors surveyed are relatively small outfits with annual revenues of up to seven millions dollars (U.S.). This paper presents the results obtained from analyzing 49 survey responses from HDD contractors in the United States and Canada. An industry survey was conducted in order to gain a better understanding of this multi-billion dollar industry, which is relatively unfamiliar to many in the construction sector. Applications of horizontal directional drilling span across the civil engineering spectrum from mineral and oil exploration to the installation of telecommunication lines. Currently, in North America alone, there are 17 manufacturers of HDD rigs and accessories and several hundred dedicated horizontal directional drilling contractors. Perhaps the fastest growing segment in the underground trenchless construction industry is Horizontal Directional Drilling (HDD). Overall, the survey opens a window into the Horizontal Directional Drilling industry, providing valuable information regarding: technology capabilities limitations and applications characteristics of the industry and the outfits which provide the service and the risks and concerns that a contractor faces when performing HDD installations. As for consultants and owners, the information included in the report may prove invaluable as the statistics regarding productivity and installation costs can be used for obtaining budgetary figures and constructing preliminary schedules. Manufacturers can greatly benefit from the sections dealing with industry needs and typical problems encountered during directional drilling projects. Additionally, contractors can learn from the collective experience of others when attempting to enter a new field such as environmental installations. The information provided in the report is intended to enable HDD contractors to benchmark themselves in comparison with industry statistics. About the after-sale service, how can you solve the problems occurred of your overseas customer in time?Ī: The warranty of our machine is normally 12 months, during this period, we will arrange the international express immediately, to make sure the replace parts to be delivered as soon as possible.The following report was prepared for contractors, manufacturers, owners, consultants, and others involved in Horizontal Directional Drilling (HDD) projects. What is the delivery time of your machine?Ī: In general, the delivery time of our machine is about 30 days, customized machine will be delivered as the negotiation with our clients. Support the diverse needs of customers, the machine can be increased with the automatic drill pipe handling device, automatic anchoring system, cab, air conditioning wind, cold start, freezing mud, mud washing,mud throttling and other devices.
