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.
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.
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.
PROJECT PURPOSE (Describe the project, identify major issues, clarify the vision, and describe the strategies used to create the desired outcome.)
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.
With the constrained scenario, traffic flow has improved, commute time has decreased, workers are getting to their places of business faster, and the businesses themselves are finding that they can transport their goods in a more timely fashion. The measures that were employed consist of adding directional bike lanes to the bridge, restriping the bridge combined with timed directional transition of the middle 5th lane, additional bus routes, and converting old buildings into domiciles. Although these measures have helped to improve traffic flow in the region, capital will have to be spent at a future date in order to add additional
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).

To perform this structural change using Christensen and Knudsen (2013), four-step design method, I plan to incrementally evaluate the mission and environment, rule out any bias opinions, perform an analytic thinking of organizational and individual operations, eliminate redundancy among stakeholders, provide small groups for conducting a majority rule voting style this is performed in determining the last determination, consider all corollaries and lastly contemplate the cost (Christensen & Knudsen,
Since the early days, the men try overcome environmental challenges and, in this process, ends up creating amazing masterpieces of engineering. Among this works, the bridges appears as the clearest representatives of how the mankind could adapt to Earth’s contours. If the shape of landscape can’t be changed, the bridges are the solution to link two places and allows the connection of the traffic to improve aspects such as the communication and the trade. Depending to the need, to the sources and to the environment, the bridge can be constructed in a specific configuration. There are five main sorts of bridges configurations. First, there is the simplest bridge, the beam bridge. Second, the arch bridge, one of the oldest kind. There are the truss, composed of set of trellises. Lastly, there are the cable-stayed and
Although the Tacoma Narrows Bridge is oft considered “the most spectacular failure in bridge engineering history”, it was far from being the first unsuccessful suspension bridge. There were ten prior suspension bridges that failed due to unaccounted wind/oscillating forces. However, the Tacoma Narrows Bridge collapsed 50 years after the last bridge, and it was the most expensive and longest- more than double any previous bridge- that is the reason why its failure is so significant. The remains of this bridge now serve as “one of the world’s largest manmade
The bridge we are modeling our design after is the Waddell “A” Truss Bridge, also known as the Linn Branch Creek Bridge in Parkville, Missouri. The structure was constructed in 1898 and designed by the engineer John Alexander Low Waddell. Historically, the bridge was used as a short-span railroad bridge until 1939 when it became exclusively used for road traffic on Missouri Hwy 4. Furthermore, in 1981 the bridge was relocated to its current location, English Landing Park, where it is used for pedestrian-related transportation purposes. Additionally, there is a second known Waddell “A” type truss bridge in the US. It is located in Shreveport, Louisiana and known as the Cross Bayou Bridge, previously used for railway purposes but now abandoned.
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.
Prior of this time, most bridge design were based on trusses, arches, and cantilevers to support heavy freight trains. Automobiles were obviously much lighter. Suspension bridge design had been envolving into producing bridges of maximum grace, lightness and flexibility which actually was more suited for carrying lighter cars and not heavier train. Unfortunately, engineers did not fully understand the response of the suspension bridge design to these poorly understand forces. The second reson was due to the excitation of torsional mode. The Tacoma Narrows Bridge was built with shallow plate girders instead of the deep stiffening trusses of railway bridges, in which trusses allowed wind to pass through but plate girders, on the other hand, present an obstacle to the wind. As a result of its design, it was proved that the bridge was too light and unstable. And causing alloping Gertieaction which were driven by the wind were being experienced by the bridge.
The Three Gorges Dam on the Yangtze River will probably be finished by 2009 and will be the largest hydroelectric dam in the world.
