CASE STUDY Assignment (10%) On July 10, 2006, a husband and wife were traveling through a connector tunnel in the Big Dig tunnel system in Boston. This system carries Interstate 93 beneath downtown Boston and extends the Massachusetts Turnpike to Logan Airport. As the car passed through, at least 26 tons of concrete collapsed onto it when a suspended concrete ceiling panel fell from above. The wife was killed instantly and the husband sustained minor injuries. The Massachusetts attorney general's office issued subpoenas next day to those involved in the Big Dig project. Soon, a federal investigation ensued. The National Transportation Safety Board (NTSB) released its findings a year after the incident. The focus of the report was the anchor epoxy used to fasten the concrete panels and hardware to the tunnel ceiling. This product was marketed and distributed by Powers Fasteners, Inc., a company that specializes in the manufacturing and marketing of anchoring and fastening materials for concrete, masonry, and steel. Investigators found that Powers distributed two kinds of epoxy: Standard Set and Fast Set. The latter type of epoxy, the one used in the collapsed ceiling tile, was susceptible to creep, a process by which the epoxy deforms, allowing support anchors to pull free. The investigators concluded that this process allowed a ceiling tile to give way on July 10, 2006. According to the NTSB report, Powers knew that Fast Set epoxy was susceptible to creep and useful for short-term load bearing only. Powers did not make this distinction clear in its marketing materials the same materials distributed to tunnel project managers and engineers. Powers, the report continued, failed to provide the Central Artery/Tunnel project with sufficiently complete, accurate, and detailed information about the suitability of the company s Fast Set epoxy for sustaining long-term tensile-loads. The report also noted that Powers failed to identify anchor displacement discovered in 1999 in portions of the Big Dig system as related to creep due to the use of Fast Set epoxy. On the basis of the NTSB report, Powers was issued an involuntary manslaughter indictment by the Massachusetts attorney general s office just days after the release of the report. The indictment charged that Powers had the necessary knowledge and the opportunity to prevent the fatal ceiling collapse but failed to do so". The NTSB also targeted several other sources for blame in the incident (although no additional indictments were made). It concluded that construction contractors Gannett Fleming, Inc. and Bechtel/Parsons Brinkerhoff failed to account for the possibility of creep under long-term load conditions. The report indicated that these parties should have required that load tests be performed on adhesives before allowing their use and that the Massachusetts Turnpike Authority should have regularly inspected the portal tunnels. It asserted that if the Authority had conducted such inspections, the creep may have been detected early enough to prevent catastrophe. Question : please discuss this case according to ethical issues with giving reference from NSPE Code of Ethics. NOTE: 1. between 400-500 words. 2. Plagiarism (Maximum 20%) 3.
