Construction Of Bridge Construction Project

When bridges are poorly constructed, they may fail due to load they carry, collision by derailed trains or even by vehicles that lose control leading to catastrophic incidences. However, if bridges are well-constructed, the chances or injury are greatly minimized in the event of an accident. Discussed in the subsections are the requirements of AS 5100 standards in relation to cable-stayed bridges and include design requirements for bridges, bridge aesthetics, bridge functional requirements, bridge component design requirements and bridge construction

In Washington, the Interstate 5 bridge, which crossed the Skagit River, collapsed last month. The damage of this accident included two cars broke and three persons injured. According to officials, the bridge fell into the river after the large truck hit a beam. The bridge had a risky condition called facture critical. The U.S has a lot of bridges; however, nearly two thousand bridges were built between the middle of 1950s and the 1970s, so those ones are obsolete bridges. In addition, back then, the government cut corners in bridge buildings to cost reduction. Although gas and diesel taxes attempted to allocate to restored the bridge, the government cloud not collect money enough to repair the bridge because people began to use efficient vehicle.

Critical incidents require immediate action (Levinson & Granot, 2002). Additionally, they also require ongoing support in order to ensure that they are correctly managed and the long-term effects are mitigated (Schneid & Collins, 2001). Addressed here are four specific events - earthquakes, floods, hurricanes, and tornados. There are ways to mitigate the damage of these events, and there are also ways to try to prepare for them. Additionally, the type of response to these events is important as is the recovery from them. For earthquakes, mitigation is limited. It is possible to build houses and buildings stronger and more able to withstand shaking, and in earthquake-prone areas the cabinets often have latches and large appliances are strapped to the wall (U.S., 2007). People who live there should also have emergency supplies of food and water, and should be prepared for an earthquake by knowing information about evacuation routes (U.S., 2007). The response to earthquakes and the recovery from them are usually strong, because the areas that are most prone are also most prepared. When an earthquake hits in an unusual area, however, it can take much longer to help people and to rebuild the infrastructure.

Disasters are bound to strike at a given time and they more often find us unaware, this is the sole reason why the majority of the disasters that happen are usually fatal and destructive. This then calls for the need to try as much as possible to prevent these disasters and in particular in our cities. This is due to the fact that in the cities there are large populations that live close to each other or work in offices crammed together hence the likelihood of a disaster turning absolutely fatal if and when it strikes. However, due to the inevitable nature of these disasters, it is upon us to make adequate preparations that can enable us to minimize the effects of the natural disasters as much as possible when and if they happen.

Risks management is an important step during the process of a project. Failing to manage a risk may result in unforeseen event happening and a project’s failure. For example, with limited budget, an unforeseen event or an accident occurs in the middle of a project and this matter has not been considered and needs a big sum of expense, then the project may be stopped because of this unexpected event. We should know it is necessary to understand how to identify risks and assumptions based on the information. After identifying risks, it is important for project managers to set contingency plans to prevent and deal with these risks when they occur. Of course, several problems may happen during considering

The same problem would occur every winter and political leaders thought it was time for a solution to be found. Every winter the East River would freeze over, making it difficult for the citizens of Brooklyn to get to New York City. A solution to this problem would be the building of the Brooklyn Bridge. With the backing of political boss, William Tweed the construction of the bridge would soon be underway. After 14 years of construction and much controversy the Brooklyn Bridge officially opened May 24th 1883.

Maintains clear detailed records of meetings and events that take place during the construction process.

The cost of building a new bridge is one of the most important parts for the people there who have to pay for it and building a very expensive bridge makes a lot of people sceptic.

During an engineering project life cycle, the common risk management process (risk identification, risk impact assessment, risk prioritization analysis, risk tracking, and risk mitigation planning implementation) meet the required protocols for early and continuous risk identification. The first step, risk identification, brainstorms potential risks that may develop during the engineering system to include environmental or human hazards. The second step, risk impact assessment, clarifies and details the damage of the risk. The third step, risk prioritization analysis, creates a hierarchy of the risks and determines which risk needs to be addressed first then so on. The follow-on steps have two different paths, one path is risk tracking and the other is risk mitigation

Bridges are structures that become very susceptible as time passes. In Oregon there have been many bridges being identified to be seismic vulnerable. In an article by Ed Jahn, he sates, “nearly sixty percent of state-identified lifeline bridges likely to collapse or be potentially taken out of use after a quake” (Jahn). Bridges are a whole different story because they aren’t easy to be re-evaluated when they are used constantly by people to get around. The problem with many of these structures, though is that more than half of these bridges were built before 1970 (Jahn). Because of this they aren’t reinforced with new building codes making them highly vulnerable to any disaster to the point of collapsing. It isn’t an easy thing to fix the problems with a bridge because many seem stable but are still at great risk. It is known that “Today, they're still building fracture critical bridges with the belief that they're not going to break,” (Rosenker). Even when a bridge is being identified to see if it’s stable a lot of the time they are thought to be ok, but are really in a bad condition. Because they aren’t fully evaluated, and if a disaster were to hit in a certain location it could cause the bridge to

This paper explores the construction aspects of arch bridges, specifically the New River Gorge Bridge near Fayetteville, West Virginia. Arch bridges are one of the oldest types of bridges and have been used for thousands of years across the world. These structures can be constructed of stone, brick, reinforced concrete or steel and can span thousands of feet across wide rivers or deep valleys. The construction of arch bridges relies on the concept of compression and begins with the load at the top of the arch, or keystone. The New River Gorge Bridge in West Virginia was completed in 1977 and is a true engineering marvel. Its construction and existence allows drivers and cargo to traverse the New River Gorge efficiently and safely, an otherwise impassable obstacle.

Construction projects can be extremely complex and fraught with uncertainty. Risk and uncertainty can potentially have damaging consequences for the construction projects. Therefore nowadays, the risk analysis and management continue to be a major feature of the project management of construction projects in an attempt to deal effectively with uncertainty and unexpected events and to achieve project success. Risk is inherent on construction projects and disputes frequently arise. One in four construction projects results in a dispute that leads to arbitration or litigation. With large scale, complex projects the likelihood of serious, time-consuming and expensive claims increases.

In order for a home building project to survive its purpose, risk analysis is essential so that occurrences that may affect the projects in the end can be identified, analyzed, assessed, managed and monitored. Because of the risky processes that are involved in the projects of home building construction, risk analysis and mitigation is the most useful tool in achieving good project and planning in home buildings as well as other constructions. If good risks management procedures are well conducted, the team’s level of confidence will be boosted, and this will enable or project to run and smoothly achieve its goals while facing and tackling each risk. Risk management will also come in handy as time will be saved as well as the

Because of advancements in today’s technology in construction field, many types of bridges are being constructed depending on the requirement and their suitability for the situations.

The choice of a design concept for a bridge foundation is guided by various factors; several of these
