GTR’s Les Chernauskas, Jonathan Ernst and Bill Oder recently presented at DFI’s annual conference in Denver. These presentations showcased GTR’s wide range of services and capabilities. Bill Oder and Les Chernauskas presented on an extensive research project that evaluated Thermal Integrity Profiling (TIP) on several drilled shafts installed by HUB Foundation at their yard in Chelmsford, MA. The research culminated in proposing a new temperature based criteria for TIP, which will hopefully help the industry, particularly in situations where concrete volume is not accurately known or logged. Jonathan Ernst presented on the “Replacement of MNRR Bridge over Atlantic Street” Project in Stamford CT involving an earth support system that effectively tunneled beneath five (5) Metro North Railroad tracks at each proposed bridge abutment location and supported a “Jump Span Bridge” that allowed for rail traffic to overhead. The SOE served the dual purpose of retaining lateral earth and surcharge pressures while also providing vertical bridge support during construction while trains actively travelled above during the installation of the propose micropile abutment foundations.
