  • 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 ...

  • The Effectiveness of Intrawell ground water monitoring statistics

    Abstract   The reality of the new statistical evaluation requirements for ground water at Subtitle D facilities are being felt nationwide. All too often these requirements are resulting in unnecessary increases in ground water monitoring costs and erroneous indications of facility impacts. For example, a common situation faced by many older facilities is that there is ...

  • Zerovalent Iron nanoparticles for treatment of ground water contaminated by Hexachlorocyclohexanes

    Ground water and aquifer samples from a site contaminated by hexachlorocyclohexanes (HCHs; C6H6Cl6) were exposed to nanoscale iron particles to evaluate the technology as a potential remediation method. The summed concentration of the HCH isomers in ground water was approximately 5.16 µmol L–1 (1500 µg L–1). Batch experiments with 2.2 to 27.0 g L–1 iron nanoparticles showed that more than 95% of ...

  • DHL logistics campus ground water protection case study

  • Response of frames seismically protected with passive systems in near–field areas

    The present paper analyses the behaviour of moment resisting frames in reinforced concrete subject to earthquakes recorded in near–field areas. In these areas, the signals show impulsive–type accelerograms, with velocity and displacement peaks higher than in far–field zones especially for the fault–normal component of the ground motion velocity in the direction of propagation of the wave, which ...

  • Fibermesh 650 Macropolymeric Fibers Replace Rebar for Crestline Library Project in Crestline, CA Case Study

    STK Architecture designed a beautiful public library, built to LEED Silver Standard for the town of Crestline, California. The parking lot paving and walkways utilized Fibermesh 650 high strength macropolymeric fibers instead of rebar to save money, improve durability and increase crack resistance. High strength macropolymeric fiber reinforcement for soil supported slabs was adopted into ACI 360 ...

  • The Investigation, Assessment and Design of a Rehabilitation Solution Following the Failure of an Asbestos Cement Force Main in Israel

    Following failure of a 50” Asbestos Cement force main in Tel Aviv, Israel, a failure analysis was undertaken to determine the cause of failure and the risk of further incidents. This identified the possibility of further catastrophic bursts of the force main. Fully structural rehabilitation was designed using a hybrid reinforced concrete and ferrocement approach in order to meet all of the ...

  • Titan Geosynthetics: A Major Solution for CN Rail - Case Study

    The Canadian National Railway (CN Rail) wanted to build an additional 6-track extension at the Transcona yard in Winnipeg, Manitoba. Heavy rail cars were expected to pass over this extension area and CN Rail was looking for an economical, fast, environmentally friendly and technically sound solution for their track extension. The site had swampy conditions with wet and soft clay soils. In fact, ...

  • Funding a Job Guarantee

    Adopting a conventional view of the need for governments to raise the funds they spend, I have argued that a well-designed Job Guarantee (JG) programme could be funded entirely from the savings and additional revenues it would generate (Harvey, 1989; 1995). In contrast, JG advocates working in the Post Keynesian tradition have grounded their proposal for funding such a programme on a more ...
