Essay on Millau Viaduct Project Management

After crossing the river we follow the Teesdale Way to the remains of the Tees Viaduct. This was built in 1861 to carry the railway to Kirby Stephen and Middleton-in-Teesdale. The viaduct had six tall piers, four of which stood in the river. The line closed in 1965 and the viaduct was demolished in 1972. Plans were put forward, in 2002, to erect a rope suspension bridge between the two remaining piers. If this ever came to fruition, it would be the world’s longest rope suspension bridge at a distance of 600 feet (183m).

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

The Walterdale Bridge started construction in Edmonton, Alberta, July 2013 with an estimated completion of fall 2015. The year is now 2016 with a completion date of 2017. The project was first established with a purpose to replace the pre-existing bridge built between 1912 - 1913, which according to the city of Edmonton (2016) is reaching the end of its service life. The Walterdale Bridge will connect the intersection of Queen Elizabeth Park Road and Walterdale Hill on the River’s south side, to the River Valley Road/Rossdale Road/105 street intersection on the north side. By conducting a critical analysis of the project, from the project management perspective and using the project management methodologies as stated in the Project Management Body of Knowledge, this case analysis will analyze the issues, failures, and causes that plague the Walterdale Bridge project.

Initially, suspension bridges before 1940 were made of piers, towers, wires, anchorages, and roadways. Piers were the main foundation for the suspension bridges. There usually were two of them, which were made out of cement and were entrenched in ground underneath the body of water that the bridge was spanned across. Towers were built on top of the piers to provide a means of connection for the roadways and wires. Wires were connected to the towers, roadways, and anchorages to provide tension support for the weight of the bridge. The anchorages were large cement platforms that were planted into the ground on either side of the land so that the wires could be connected to it. Lastly, the roadways were the main point of the suspension bridge. They usually were wide enough to provide four lanes of traffic and stretched from one side of the bridge to the other. This was the basic design of the suspension bridges

You have been asked to create a budget proposal for one of these businesses: Papa Geo’s Restaurant, The Cutting Edge Landscaping, or Wireless World Electronics Retail Store. This week you will begin working on the proposal by drafting the Executive Summary.

The project 9 Crescent Road (A) meets the required criteria by demonstrating how analysis, research, context, budget, preparation and development of a brief inform a design proposal.

Throughout the course of history there have been many advances in the world of infrastructure, mostly occurring in the 1800’s and the 1900’s. Infrastructure is defined as the basic physical and organizational structure needed for the operation of a society or enterprise, or the services and facilities necessary for an economy to function. This definition shows how important infrastructure is to people’s lives today. It affects how people live, travel, and communicate with one another. Three men who made huge contributions in the world of infrastructure were Robert Moses, Richard Ravitch and Othmar Hermann Ammann. All three of these men were involved in designing numerous landmarks, highways, bridges, tunnels, and other forms of infrastructure that today we take for granted. Although all of these men were involved in infrastructure in the New York metropolitan area, their contributions, personalities, and the public’s opinion of them were all different.

Money being brought in from the bridge is vital for bondholders to be pleased. Lately, the revenue statistics have been lesser. To heighten these statistics the toll has to be raised. While citizens are unhappy with this belief, the bondholders get the final say. Loans are given with the intent to be received back in a considerable time frame. Bondholders invested in this bridge to provide for the community and their thoughtfulness is not being paid back. Change has to come and needs to come now, this will start with a higher toll

Boston’s Big Dig was a massive road infrastructure project planned to improve the flow of traffic, alleviating chronic congestion across Boston and the surrounding commuter areas, and to replace the outdated elevated Central Artery road that effectively split the city in half. The plan was to replace the Existing Central Artery, a crumbling elevated six-lane highway, with an extended underground highway, and a 14-lane two bridge crossing that would Extend Massachusetts Interstate 90 from its former end, south of downtown Boston, through a tunnel under South Boston and Boston Harbor. This project would prove to be a technological marvel and the most technically challenging infrastructure ever undertaken in the US. Building a tunnel underneath

During the construction, two half-spans being assembled 50 meters above ground level had a misalignment of 4.5 inches or 114mm in camber. It was suggested by John Holland & Constructions to use a kentledge to weigh down the higher section of bridge. It so happened that they had ten, eight tonne concrete blocks on site. These were placed halfway along the higher span to

It is shaped in a way to transfer weight to the towers and anchors with its tension (O'Connor, 1971, p. 372). Cables are made of high strength wires spirally bound to form a rope (O'Connor, 1971, p. 372). Vertical cable suspenders that are fastened to the main cables hang the actual roadway. Stiffening girders and trusses are along the side of the bridge to distribute concentrated loads and help to keep the motion of the bridge at a minimum (Troitsky, 1994, p115).

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.

The Three Gorges Dam on the Yangtze River will probably be finished by 2009 and will be the largest hydroelectric dam in the world.

The Channel Tunnel is one of Europe's biggest infrastructure projects ever. The 50.45km long tunnel has fulfilled this old dream by linking Britain and the rest of Europe. The idea of a fixed link between Britain and France was first mooted by a French engineer in 1802; it connects England and France 50m below the seabed of the English Channel. It's not just a tunnel, but a huge infrastructure containing massive machinery and control systems in an underwater tunnel system (Lemley, 1995; Kirkland, 1995). In 1990 the service tunnels broke through at the halfway point. The main rail tunnels met on May 22, 1991 and on June 28, 1991, each accompanied by a

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.
