  • GPR goes underground: Pipe Penetrating Radar

    Abstract: Pipe Penetrating Radar (PPR) is the underground in-pipe application of ground penetrating radar (GPR) either robotically or by manned entry to reveal wall thickness, delamination, voids, and other conditions that enable more precise determination of pipeline integrity and verifications for trenchless technology rehabilitation. PPR, when applied to pipe-bursting applications, can ...

  • Assessing buried infrastructure deep under buried infrastructure

    In preparing for its water future, the Region of Peel (Peel) adopts a unique assessment strategy for a newly constructed potable water transmission main that extends deep underground through the heart of Peel Region. The effort is paying off, with Peel decision makers gaining a better understanding of this pipeline as it comes into ...

  • Evolution of underground aqueducts in the Hellenic world

    Historical and archaeological evidence shows that ancient Hellenes had developed underground aqueducts since the prehistoric times. However, innovative methods of underground aqueducts were developed in Hellas mainly during the Archaic, Classical, Hellenistic, and Roman periods. Since the well-known tunnel at the island of Samos, Hellas, was designed and begun its construction (ca. 550 ...

  • Canada’s Other Energy Boom – Energy infrastructure is on the move.

    When it comes to energy infrastructure, Canada is on the move. Of course, that may seem like nothing new, given Canada’s lengthy energy history, particularly in the oil and gas industries. In this latest chapter, however, electricity is playing a major role. A confluence of factors have helped spur the need for more generation, which in turn is driving still another form of energy ...

  • No Negative Impacts to Underground Infrastructure and Communication Lines using RegenOx at Site with High Concentrations of TRPH

    Kennedy Space Center, FL The Launch Equipment Shop (LES) at Kennedy Space Center, part of NASA's famed Vehicle Assembly Budding complex, has conducted highly specialized manufacturing fabrication, and assembly work for the space program since the early 1960s. Leaks from an underground storage tank (UST) led to notable fuel oil contamination of soil and groundwater, including a layer of ...

  • Spatial Layout Planning in Sub-Surface Rail Station Design for Effective Fire Evacuation

    Spatial layout planning is an important part of the underground railway station design process, taking into account its need-driven nature and the resulting infrastructure that is sized on demand. The predicted passenger flow rates are the underlining factor and are divided into 'levels of service' for space planning considerations. This paper reports on the development of a knowledge-based ...

  • RegenOx™ treats petroleum hydrocarbons surrounding sensitive underground infrastructure at a defence facility

    Former fueling operations at Scott Air Force Base resulted in soil contamination containing high levels of benzene, ethylbenzene, methyl tertiary-butyl ether (MTBE), and naphthalene. Underground storage tank removal and source area excavation were planned to treat the unsaturated soil. However, subsurface investigations revealed piping, fiber-optic communication lines and other utilities present ...

  • Making remaining life predictions for better pipeline asset management

    ABSTRACT Most underground assets owners would like to know what the probability is for failure of a given pipeline asset as a function of material type, function type, age of the asset, geotechnical environment, and other factors, when we know past failure distributions, predominant failure mechanisms, and other attributes. While most underground utilities have collected voluminous data that ...

  • Asset management and nondestructive evaluation of force mains in New York City

    Management of infrastructure assets has been gaining increased attention recently because of aging infrastructures. Wastewater infrastructures, such as sewers, force mains, etc., maintained by various municipalities across the nation are at increased risk of failure since they are buried underground and are usually scheduled for maintenance/repair only after a breakage. Force mains are a vital ...
