TL;DR: The findings of the first two phases of the Strategic Highway Research Program 2 (SHRP 2) Project R01: Encouraging Innovation in Locating and Characterizing Underground Utilities are presented in this paper.
Abstract: This report presents the findings of the first two phases of Strategic Highway Research Program 2 (SHRP 2) Project R01: Encouraging Innovation in Locating and Characterizing Underground Utilities. The project identified existing and emerging technologies and developed recommendations for subsequent research in this area. The report provides a thorough and insightful review of locating practices, current and emerging technologies, and recommended improvements. A third phase was added to this project to develop software to serve as decision support for identifying effective utility-locating methods for particular site or project environments. The software will expand on capabilities already developed under the R01 project.

TL;DR: The Trenchless Technology Center, in collaboration with industry associations, has developed comprehensive, yet easy to use interactive software for the evaluation of alternative construction methods that can be employed in the installation and rehabilitation of buried pipes and manhole structures utilized in municipal applications.
Abstract: The Trenchless Technology Center, in collaboration with industry associations, has developed comprehensive, yet easy to use interactive software for the evaluation of alternative construction methods that can be employed in the installation and rehabilitation of buried pipes (gravity driven and pressurized) and manhole structures utilized in municipal applications. The decision support software was implemented in an on-line format, so it can be accessed simultaneously by multiple users over the internet via a web-portal named TTWorld. A Social Cost calculator was added to the web-portal to assist users in estimating the social costs associated with the various construction methods. The software is updated regularly to include emerging and evolving technologies and materials, and is available in both, English and Spanish. Future developments will focus on enabling the software to accept input data directly from relational databases associated with commonly used GIS software packages.

TL;DR: In this paper, a synthesis of current and emerging non-destructive technologies (NDT) for assessment management of culverts is presented. But the authors focus on developing a rapid and cost effective evaluation methodology for the condition assessment of the culverts to estimate their remaining service life.
Abstract: This paper focuses on developing a rapid and cost effective evaluation methodology for the condition assessment of culverts to estimate their remaining service life. Nondestructive inspection methods are selected based on their reliability and effectiveness. A synthesis of current and emerging non-destructive technologies (NDT) for culverts assessment management is presented. The information presented intends to serve as a database for a generalized algorithm for selecting a NDT scheme for condition assessment of culverts and their embedment.

30 Jul 2009TL;DR: In this article, a steerable ground piercing tool with a rotatable chisel has been described, with the chisel having an asymmetric tip and a first impact surface for receiving a reciprocating action impact to drive the tool through the ground.
Abstract: A steerable ground piercing tool includes an elongated outer housing having a lengthwise extending bore and an inner assembly at least in part disposed within the outer housing. The inner assembly includes a rotatable chisel having a longitudinally extending shaft at least in part disposed within the housing bore. The chisel has a first end defining an asymmetric tip and a second end defining a first impact surface for receiving a reciprocating action impact to drive the tool through the ground. The inner assembly further includes a conversion mechanism to selectively convert upon activation thereof at least a first portion of the reciprocating action imparted to the first impact surface into combined reciprocation and rotation of the tool.
