The Big Dig Research
10/29/2014

The Big Dig was a megaproject in Boston that consisted in rerouting the Central Artery into a 3.5-mile tunnel, building the Ted Williams Tunnel, the Leonard P- Zakim Bunker Hill Memorial Bridge over the Charles River, and the Rose Kennedy Greenway in the newly vacated space. The project took 15 years to get done and finally concluded on December 2007. Even though there were several issues and problems along the way that today teach us lessons about managing megaprojects including increase of cost estimations, risk control and collaboration between the involved groups, the Big Dig was a success considering its complexity and technical challenges.

One interesting concept during the Big Dig construction was the way government mitigated risks all along the project. Some examples of mitigation was the promise to not shut down any of the Central Artery’s six lanes during construction, to work with Gillette to not affect its underwater infrastructure, to build temporary roads for the post office’s distribution station or promising environmentalists to preserve as open space three-quarters of the land that the Artery’s demolition would create. All of this was with the purpose of protecting stakeholder’s interests and then make sure there was no local opposition to win federal funding. I find it interesting how because of mitigation efforts, more than 80% of Boston residents and 66% of state residents supported the Big Dig project. This is a great example of the importance of taking into account the needs of all stakeholders involved in order to minimize negative impacts that could later have consequences on the project.

On the other hand, one of the main issues that arose during construction was the poor cost estimation that was made. “ Initial estimates put the Big Dig project at $2.6 billion, but when it was all said and done, the project cost nearly $15 billion.” (Fryer, 2012). There are plenty of reasons why this happened

    ANALYSIS: The meeting was an information session for residents living in Mahwah, Allendale, Oakland, and Ridgefield to understand the history and current status of the Municipal Pipeline Group (MPG). The Municipal Pipeline Group was started by Mahwah Council members after town residents raised awareness of the Pilgrim Pipeline Project. After drafting and approving both a resolution and ordinance, town officials in Mahwah decided to contact neighboring towns and cities who would also be impacted by Pilgrim Pipeline. In order to fight a potential legal battle, the Municipal Pipeline Group was created with each town/city contributing $5,000.…

    Among the most pervasive issues that continue to plague American society is deteriorating infrastructure standards. Once regarded as the hallmark of a financially stable nation, infrastructure construction and maintenance has recently experienced persistent periods of financial neglect.. Everything ranging from bridge inspections to waste management has shared the brunt of this trend. However, the most widely affecting facet of infrastructure, if based on nothing other than usage rates, is roads. According to 2013 Report Card for America’s Infrastructure provided by the American Society of Civil Engineers—which conducts grade-based reviews on infrastructure standards every four years—the national average infrastructure rating was a meager D+; Roads, specifically, were rated even lower at a D. Most mainstream voices tend to suggest that the only solution is to acquire more funding; this, however, is a moot point considering the extent of time, effort and political leverage necessary to influence change under the current system. Instead, a more appropriate solution would require a broader examination of the market structure as a whole. As global markets continue to perform abysmally and legislators struggle to meet basic budgetary duties, the time has come to reconsider the entirety of government’s role in infrastructure.…

    One recent autumn evening while I stood in line to comment at a public hearing about a proposed natural gas pipeline through Virginia, I befriended an inspirational environmental advocate by the name of Bear Redstar. Bear grew up in a Lakota family as a part of the Dakotas’ seven Sioux tribes. Bear’s initial exposure to the destructive potential of a pipeline occurred while he worked as a welder for ExxonMobil on the Trans-Alaska Pipeline, where he witnessed the steel pipe rupture and release crude oil into the environment. Upon his return home, he advocated alongside Native American community members against the Dakota Access Pipeline. A few months ago Mr. Redstar, moved to Roanoke, Virginia, again facing the trouble of a pipeline. He and I were at the public hearing to warn the Appalachian community of the risks associated with a pipeline.…

    For instance, guidelines have since been issued to better detect problems with gusset plates and bridge design. Major issue in this nightmare were the gusset plates so now a lot of states in the U.S have stepped up bridge inspections and repairs so that nothing like this happens in they’re own state. As well bridge owners have to conduct load capacity calculations to verify that the stress levels in all structural elements, including gusset plates, remain within applicable requirements whenever planned modifications or operational changes may significantly increase stresses. Obviously as a result of the collapse the state of Minnesota constructed a new bridge, which was said to last 100 years. The new I-35 is state of the art and has received many awards like the America’s Transportation Awards’ Grand Prize in October of 2009 and it was named one of America’s 10 best transportation projects in September of 2009.…

    He used to write about how the workers were almost 75 feet deep into the water because construction at the foundation level was generally that difficult to be carried out. However he was optimistic that the construction was going to go without a glitch. Initially the plan was going very smoothly since the gigantic steel cofferdams that were used to reproduce the formation of the Jersey Bridge tower were more reliable and easier to place than the caissons which were used to construct the Brooklyn Bridge. The cofferdams were not pressurized hence the bends were not going to be an essential hazard to the construction unlike the caissons…

    “At least 12 tons of concrete fell from the ceiling of one of Boston 's Big Dig tunnels, crushing a woman in a car and again raising concerns about the integrity of the massive highway project that is the central artery through the city, A steel tieback that held a 40-foot ceiling section over Interstate 90 eastbound gave way late Monday night in the tunnel, a main access way to Boston 's Logan International Airport. The tunnel was closed indefinitely as crews worked to remove about 30 ceiling slabs in a 200-foot section where the collapse occurred, Authority Chairman Matthew Amorello said Tuesday. Milena Delvalle, 38, of Boston 's Jamaica Plain section, was pronounced dead at the scene. Angel Delvalle, 46, managed to crawl out a window of their crushed car with less than a foot of clearance and suffered minor injuries, according to State Police. Their car was partially crushed under at least four ceiling panels, each weighing 3 tons. The vehicle was in the left lane, giving the driver 's side more protection as panels came to rest also on a left-side service walkway that is elevated several feet above the road. Milena Delvalle was a native of Costa Rica, and the two were newlyweds. They were on the way to the airport to pick up his brother and sister in law, who had been vacationing in his native Puerto Rico. We feel awful about what happened last night," Amorello said. "It 's an awful, awful tragedy. This is an awful situation that occurred." Amorello appointed a state police major, two outside consultants and a team from the Federal Highway Administration to assist…

    This project made groundbreaking revelations; this included using engineering techniques which had not been used in the type of scale to their extent. Two types of engineering practices were the use of caissons for the foundation and a suspension bridge system, both of which had been limited in use before the Brooklyn Bridge. The way in which Roebling approached the Brooklyn Bridge was a critical component of the management project; he had a vision in mind before being granted the project and executed the project according to his elaborate plan. Although the construction of the Brooklyn Bridge was incredibly successful, the approach taken had left the very little room for error for the designers. Much of the success lies in the fact that the Roeblings had gotten most of the characterization correct. However, without any contingencies, the plan lacked much flexibility to adjust to any major setbacks to the project.…

    London Bridge

    • 2110 Words
    • 9 Pages

    When people in the United States today hear the term "London Bridge," they are most likely to think of one of the most peculiar sights anywhere within the United States that of the London Bridge in Lake Havasu City, Arizona. Surrounded by faked-up Tudor buildings and busloads of tourists, the large bridge is dwarfed by the majesty of the desert Southwest. The entire enterprise stands as a monument to a deep human appreciation for irony, for what else could explain the immense cost and energy that went into transporting such an immense structure such a long way for so very little purpose. But this peculiar structure in the desert is in fact not the real London Bridge at all (if any bridge can in fact lay claim to that title, which seems unlikely), but the New London Bridge, designed in 1831 by the Scottish engineer John Rennie…
