Goodwill Bridge Case Study

The Goodwill bridge’ aesthetically pleasing figure was designed by skilled architects from Cox Rayner and then passed on to the engineers at Ove Arup and Partners, to continue on with the further design preparation before the structure was to be constructed. A large well known construction company was in charge of the bridge construction, with the main contractor being John Holland.. In charge of the project was project manager Jack Sullivan, from Amtec International Construction Services.

America`s infrastructure has been a concern for years, but as populations begin to grow and structures begin to become outdated the problem has become more urgent. One focus of this infrastructure problem is bridges, which are growing weaker causing economic and social concerns. The primary controversy around these bridge failures is what is causing them and the potential they have to cause disasters. Moreover, this potential is why Americans should invest more into their infrastructure.

In the play ‘ A View From The Bridge” The protagonist Eddie, an Italian immigrant, seems to have complex relationship with who seems to be his wife’s orphaned niece Catherine throughout the whole play.

Foundation tasks are normally planned and built utilizing entrenched points of reference. The Goodwill Bridge is an unordinary bit of framework in that the type of the structure was vigorously impacted by a stylish and sculptural idea that was chosen by the customer by means of a building configuration rivalry. Not at all like most foundation tasks, there were few if any points

The estimated cost of the scheme is between £1.325-£1.35 billion. New technology will be implemented for the queen’s ferry crossing; it will be more climate resistant than the current bridge. Key feature of the new bridge include:

Calculations were performed to determine the effectiveness of the design of the platform. Allowing for a safety factor of 1.5 times the design weight of 10kg and considering the bridge must not be overdesigned; plans were made for the bridge to fail at 25kg, 2.5 times that of the design weight. According to the calculations, the bridge would hold a load of over 15kg and experience failure at 20kg in the members. These calculations were later disproven in the testing, breaking 8kg earlier than expected, due to unforseen errors. An analysis of the bridge design and calculations has been included at the end of this report.

Sam: A real life bridge that is similar to our household bridge is the Hoffstadt Bridge. The Hoffstadt Bridge is a truss bridge 96 miles south of Seattle Washington. (show picture)This bridge connects Hoffstadt Creek and Hoffstadt Mountain. The Hoffstadt Bridge is 2,340 feet long, or about 712 meters. Similar to our bridge, this bridge is supported by trusses on the bottom. The Hoffstadt Bridge also has a flat deck such as ours.

A more expensive bridge would be made out of better materials, thus the bridge would hold up against hurricanes for years and will not collapse. “The 2.8-mile span of U.S. 158 would close to one lane as crews fix concrete supports and lay a new surface, among other changes, at a cost of $28.9 million” Said Jennifer Heiss, who is the spokeswomen for the North Carolina Department of Transportation (Hampton). This just shows that in the long run cheaper bridges will have to be repaired and will cost a lot. Bonner bridge is on the list of the

In the spring of 1989, the construction of the new bridge began. The base of the Trent River was a flotilla of barges carrying the workers, cranes and equipment needed to prepare the temporary pillars that would support the new bridge, as well as maneuver the huge steel girders into place for the new bridge. It was an awesome sight for the entire town, as we watched barges float the steel girders into the harbour, one section being 74 meters in length and two more that were 54 metres each. The new steel box girder bridge had a total length of 182 metres and weighed 2,950 metric tonnes (Anderson & Trenkler, 1991). Temporary cement pillars were poured to support

the scheduling strategies adopted on this large scale project can be broken down between the two major bridges being built.

Hecox (2011) says that the arch structure of the Tillman Bridge makes the canyon walls hold the weight of both vehicles and the bridge itself. In addition, the arch structure allows a better vision of the canyon for the drivers, which was a request of the population to the engineers of the project. In the other hand, according to Jones (2015), the truss structure of the new St. Anthony Bridge also was requested by the population because they wanted to keep a truss bridge in that place. The author also affirms that the St. Anthony Bridge is a truss, but the project team proposed adding a posttensioned concrete bottom chord to the steel truss in order to reinforce it. The project team made this choice because one bridge in Minnesota has collapsed in 2007, and the engineers wanted to lessen the fracture-critical issues to avoid a new catastrophe. In addition, this posttensioning approach wiil make the structure redundant for both resiliency and long-term durability. In conclusion, both bridge's structures were right chosen in order to provide safety and beauty in both

The Interstate 35W bridge otherwise known as bridge 9340 is one of the busiest bridges in Minnesota (Karnowski). On average about 140,000 vehicles cross the bridge everyday (Weeks). The truss bridge was built back in the 1960s (Karnowski). It runs through downtown Minnesota across the Mississippi River. There are four lanes in each direction and it’s 1,907 feet long and 113 feet wide (Weeks).

By the late 1990’s, the Washington State Department of Transportation (WSDOT) began conducting studies to find solutions to the problems of traffic and the aging of the original four-lane bridge (WSDOT, 2015). Approval for a new, wider floating bridge was obtained and, in 2011, construction of concrete pontoons for the new bridge’s foundation began. The new replacement bridge is part of a massive $4.6 billion program by Washington State (and the City of Seattle) to improve transportation infrastructure via State Route 520 on both sides of Lake Washington. After approximately five years’ time, the new floating bridge opened ceremoniously in April of 2016. The program continues through 2016 with construction activities highlighted by the safe demolition and removal of the old bridge (WSDOT,

To give back to my community I decided to build a foot bridge for my local church that crosses over the spillway that is on the grounds there. I am working with the Boy scout troop I’m apart of to get the resources and help to build it. The project has been a success although I have not finished the bridge I have done a lot of work towards completing it like pouring concrete slabs for support and getting ready the metal and wood work to be added later. I selected this project because I’ve I am apart of boy scouts and the pastor of the Church it is for asked them if there was somebody looking for a project and I jumped at the opportunity and I also really like building things and working with that sort of stuff rather than desk work. This project taught me a lot about tools and carpentry and planning intricate things with a lot of people. One of the biggest obstacles was getting funding for the project and where to get the supplies. I got over this obstacle by going around asking local companies for donations and by luck one of the companies I went to actually donated all of the metal and helped me make a blueprint.

A bridge is a structure providing path over an obstacle. When constructing a bridge, obstacle can be a river, railway track or a valley and the path provided by bridge can be for a road, pedestrians, a railway, pipelines, viaducts to carry water from rich areas to dry cities, or for commercial purpose to host commercial buildings such as restaurants and shops. A bridge can also be laid to reduce the distance of travel which in turn reduces the time to reach the destination.
