At the time the design and the execution of the Niagara Falls Suspension Bridge was revolutionary, however, it’s original design was unable to keep up with the massive surge in transportation and the tremendous increase in the size of…
Urban Constructions has several policies, procedures and practices in place to protect the client, suppliers, our staff and our contractors. Limitations placed upon our team can restrict the project to what it will produce. To make this subdivision successful, we must follow these procedures.…
Most of the projects were done during the same time of each other and didn’t have to wait for one another. They had the Arizona approach and the Nevada Approach being constructed by two different companies and the bridge itself was constructed by two other…
Bridges are something that have always fascinated me. In my picture you can see I have the Julien Dubuque Bridge in the background. This bridge is a two lane bridge, it has been debated through the past years on if this bridge will be altered in the future. I think it would be a very interesting lesson for the students to look at adding lanes on the bridge. They could choose to expand the bridge into four lanes, build a second two-lane bridge, or tear down the current bridge and replace with a four-lane. During this project students would need to keep in mind that the Julien Dubuque Bridge is listed in the National Register of Historic Places. They would also have to factor in construction time and possible road detours to decide what would…
In what ways were the project planning and scope management for this project appropriate and when did they begin taking unknowing or unnecessary risks? Discuss the issue of project constraints and other unique aspects of the bridge in the risk management process. Did the project managers take them sufficiently into consideration? Why or why not?…
In order to meet this aggressive schedule, the project will require around the clock construction crews, detailed project management, good construction weather, and some modern construction techniques.…
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.…
must spend hundreds of billions of dollars annually to preserve the nation’s infrastructure—the backbone of its private-sector economy—and yet more to build the next generation of roads, bridges, tunnels, and dams. Spending so much money wisely is daunting. The good news: no matter how complex and expensive any future project is, it’s unlikely to be more so than the Big Dig, Massachusetts’s three-decade-long quest to bury and expand the Central Artery, Boston’s major interstate highway, and carve out a new underwater tunnel to Logan Airport. Conceived in the 1970s and finished, more or less, in 2005, the Big Dig is modern America’s most ambitious urban-infrastructure project, spanning six presidents and seven governors, costing $14.8 billion, and featuring many never-before-done engineering…
Assignment Discovery Online Curriculum Lesson title: Famous Bridges Grade level: 6-8, with adaptation for older students Subject area: Physical Science, Technology Duration: Two class periods Objectives: Students will: 1. Understand the benefits and drawbacks of different types of bridges. 2. Investigate the history and structural challenges of a prominent bridge. 3. Think about the challenges involved in building bridges. Materials: The class will need the following: • Computers with Internet access (optional but very helpful) • Reference materials on bridges Each group of three or four students will need the following: • Research material about a particular bridge (Web sites and books suggested below) • One long piece of butcher block paper • Pencils, colored markers, and crayons Each student will need the following: • One copy of the Classroom Activity Sheet: Bridge Research and • One copy of the Take-Home Sheet: Longest Suspension Bridges in the United States This lesson plan can be enhanced by purchasing a copy of the documentary Bridges: Design and Function at our School Store. The program airs on the Discovery Channel February 12, March 19, April 23, and May 28, 2001. Procedures: 1. Introduce the lesson by showing the class a picture of a popular bridge, such the Golden Gate Bridge (San Francisco) or the Brooklyn Bridge (New York City). Ask students to imagine what might happen if all the bridges in New York City or San Francisco were suddenly shut down. Then help the class brainstorm some ways that bridges affect our lives. For example, 1…

According to the dictionary, a bridge is a structure carrying a road, path, railroad, or canal across a river, ravine, road, railroad, or other obstacle. Bridges are essential for transportation. Whether it's a canyon, or a body of water, bridges allow travel over those gaps from one part of land to the other. The world would be forever changed without bridges.…
