Pilot tube microtunneling: profile of an emerging industry

Description

Trenchless technologies have emerged as a viable alternative to traditional open trench methods for installing underground pipelines and conduits. Pilot Tube Microtunneling, also referred to as the pilot tube system of microtunneling, guided auger boring, or guided boring method, is a recent addition to the family of trenchless installation methods. Pilot tube microtunneling originated in Japan and Europe, and was introduced to the United States in the year 1995 (Boschert 2007). Since then this methodology has seen increased utilization across North America particularity in municipal markets for the installation of gravity sewers. The primary reason contributing to the growth of pilot tube microtunneling is the technology's capability of installing pipes at high precision in terms of line and grade, in a wide range of ground conditions using relatively inexpensive equipment. The means and methods, applicability, capabilities and limitations of pilot tube microtunneling are well documented in published literature through many project specific case studies. However, there is little information on the macroscopic level regarding the technology and industry as a whole. With the increasing popularity of pilot tube microtunneling, there is an emerging need to address the above issues. This research effort surveyed 22 pilot tube microtunneling contractors across North America to determine the current industry state of practice with the technology. The survey examined various topics including contractor profile and experience; equipment, methods, and pipe materials utilized; and issues pertaining to project planning and construction risks associated with the pilot tube method. The findings of this research are based on a total of 450 projects completed with pilot tube microtunneling between 2006 and 2010. The respondents were diverse in terms of their experience with PTMT, ranging from two to 11 years. A majority of the respondents have traditionally provided services with other trenchless technologies. As revealed by the survey responses, PTMT projects grew by 110% between the years 2006 and 2010. It was found that almost 72% of the 450 PTMT projects completed between 2006 and 2010 by the respondents were for sanitary sewers. Installation in cobbles and boulders was rated as the highest risk by the contractors.

SparkUp!

Description

SparkUp! is a solution that was created by Jose Montes and Ninad Kulkarni in September of 2021. The pair noticed a few needs that they could help solve within the ASU community. Due to the Covid-19 pandemic, the average students' college experience was completely uprooted and replaced with asynchronous learning and interactions which made it difficult for students to engage with other fellow students and make new friends. This also caused students to develop sedentary lifestyles since they no longer had to walk to campus, and they developed a routine of staying confined to their dorms throughout the day. SparkUp! is a Social Media app concept that solves these issues by connecting ASU students with other fellow students by helping them engage with one another in outdoor physical activities. Members can create and host their own hiking, cycling, kayaking, or other outdoor activity and they can set them for private or open use. Users can request to join an event by RSVPing through the app, and they also can connect with their new connections by utilizing the social media aspect of the app. Lastly, the app also tracks and maintains activity metrics such as miles traveled, steps taken, and overall time spent engaging in an activity. Through the needs discovery phase which took part from September-December 2021, the solutions that SparkUp! offers were validated. This prompted further analysis which led to an overall PESTLE analysis of SparkUp!’s overall potential ecosystem, the creation of a marketing strategy and the creation of an Alpha version of the app so that potential users could test the initial designs of the concept. This testing was done during April of 2022 which is aiding in gathering the data necessary to create a Minimal Value Product for future release.
