Abstract: With an increase in trenchless methods being used for the installation of natural gas lines in urban areas, unmarked sewer service laterals present a risk of accidental and unknown cross-bores with these distribution lines. ...

Abstract: Feasibility and suitability assessments have become increasingly important for trenchless projects, as some Federal and State permitting agencies have released guidance on the information required to complete their ...

Abstract: Recently, many public transportation agencies have begun to consider changing the way that they manage highway maintenance operations. One system under consideration, already well developed for private businesses, is ...

Abstract: Horizontal directional drilling is rapidly becoming the method of choice for installing new underground systems including water, sewer, electrical, telephone, fiber-optic cables, and gas lines. Due to its minimal impact ...

Abstract: Lawyerization has become more and more prevalent in the engineering and construction industry. Some would argue the merits of firms’ retaining lawyers on staff as providing cost savings on projects through averting potential ...

Abstract: The construction industry is continuing to face the challenge of properly identifying existing underground utilities prior to engaging in new construction or renovation projects. Contractors need to know the precise location ...

Abstract: An approach to evaluate the relative criticality of different pipes in a water distribution system is presented. To quantify the relative criticality of pipelines, a term, relative criticality index (RCI), has been defined ...

Abstract: Modern infrastructure systems are highly developed, with considerable capital funding invested in them. While capital is spent on new infrastructure initiatives, the maintenance of the present infrastructure must not be ...

Abstract: This paper presents the results of field installations of high-density polyethylene (HDPE) using the horizontal directional drilling process. One each of 114 mm (4 in.) diameter standard dimension ratio (SDR) 17 HDPE pipe, ...

Abstract: Trenchless pipe replacement, or pipe bursting, is a construction method that provides an alternative for rehabilitating underground infrastructure with minimal disruption to surface traffic. It is recognized as the only ...
