Any project of construction, ‘Investigation’ takes a prominent place. Before starting a construction civil organizers should pay attention on the history, environment recommendation on the favorable or unfavorable location, economic and safe design and potential risks. On above circumstances civil engineers have to get instructions from ground investigation contractor and geotechnical engineer. At the same time engineer has to find reasons for failure, because failure affects the entire construction project.
Most of the countries in the world ,not only in our country, engineers have subjected to fail in construction due to poor investigation. The geotechnical consultants and the ground investigation contractors are responsible for planning the

Then it has been sold on 31st December 2000 to convert into a sports arena.
The number of visitors to the ”Dome” decreased although it was a fully funded project. The company had to face many financial problems during its operational year.
The main reason for the failure was unproper planning. They had transformed the original plan of “Millennium Dome” into a soccer pitch. It was due to the poor vision of authority. Lack of sufficient operational expertise, criticisms, poor execution, poor marketing strategies and mismanagement of finance; also reasons for the alone failure.
By launching several strategies like financial management and favorable planning, engineers could overcome the failure. So they understood the failure is preventable with better project planning.
Poor conceptual design of Tacoma Narrows Bridge
Tacoma Narrows Bridge was opened in 1940 in Washington. The bridge began twisting violently on November 7 the same year. The bridge snapped and crashed into the river below. That was happened due to the aerodynamic
After long and heated arguments between experts, it was decided that the Superintendent of Construction was extremely inexperienced, and that there was "recklessness in the handling of public money," on the part of the Treasury Department and the Immigration Bureau of Officials. The entire building, excluding the hospitals, had been built shoddily. After news of the problems with the building had been in the media, a lot of people involved with the construction of the building resigned their positions.
One of the most influential engineering discoveries in the past century was the ill-fated Tacoma Narrows Bridge. “Galloping Gertie” as she was known to local residents, the massive Washington state suspension bridge shook, rattled and rolled its way into the history books. Legendary in its time, the Tacoma Narrows Bridge held many records and drew tourists from around the world in its short life. However, the famous bridge is not known for its creative engineering or speedy construction, unfortunately the bridge was destined to fail. That failure in turn changed the way every building is constructed today as well as further man’s understanding of physics and the forces of nature. In this paper we will examine the history of the Tacoma Narrows Bridge from design to construction, the failure of the bridge, and ultimately the rebuilding project.
Building the stadium required various components some that included vendors from 10 states and 12 countries. In an interview with Texas Construction, Mr. Penney noted how the stadium was built section by section. He stated, “We are building the stadium from the ground up starting with the concrete decks. The two end zones will be built after the steel erection." Once the ring beam is in place, then the steel comes in. Additionally, the precast can't be set until the structure is finished "(Staff,
During the construction phase, it may occur because of - Design error - Deficient concrete production - Bad execution
Throughout history, a catastrophic bridge failure has occurred about every 330 years. With each failure, our bridges become safer. One such case of a massive collapse that drew national attention was a bridge crossing the Ohio River between Point Pleasant, West Virginia, and Kanauga, Ohio. The Silver Bridge
As society becomes increasingly more aware of the decline of the environment, it is the responsibility of the inhabitants of this Earth to both rid of further damage as well as improve the current standing of the land. More specifically, engineers must be mindful of the Earth and it’s condition as their job relates directly a great deal of the time to the environment. Civil engineers, in particular, are hands on with the environment as they are constantly dealing with the land and constructing structures that might have an affect on the surroundings. Engineers must consider a wide variety of factors while doing their job. For example, engineers cannot simply be concerned with the easiest design or a lower cost when they need to be aware of

...icient geotechnical investigation for the given development, unrealistic soil performance for given development and development constraints and restriction leading to inappropriate equipment or techniques. Consultant’s design and specifications may impose unrealistic demands on solutions. Client’s brief may fail to convey end usage; insufficient geotechnical investigation could lead to inappropriate design while on site conditions may be different to assumptions or what has been written. On the other hand flawed design and insufficient site preparation may lead to construction of structures which are likely to fail in the near future. Poor methodology and planning practices include: inappropriate or poor choice of equipment, lack of experience and understanding, lack of awareness and consequence of failure, bad workmanship and shortcutting and lack of monitoring,
It seems that in the past few years, the Geotechnical Baseline Report (GBR) has perhaps turned into the key document for construction. The GBR not only assigns much of the risk involved with the work, it serves as the basis for bid prep and is used widely in resolving disputes during construction. The use of GBR’s for contractually defining anticipated ground conditions has become a widely accepted practice in the construction business. The importance and the significant nature of these reports have increased the inquiry they receive to unparalleled levels. The basic premise of a contractual GBR has been well developed and corresponded to the industry. Despite the acceptance of GBRs, there is always opportunity for improvement. Engineers and geologists struggle to develop specific numerical baselines from a many of geotechnical properties. This especially where the geologic environments are highly inconsistent. Contractors are frustrated because they feel they are not constantly provided with the baselines they need. Owners feel taken advantage of when baselines are used to validate their claims in a manner not intended or the baselines are not valued in the dispute resolution process. It seems that there are four areas or categories the GBR’s. These could result in for a better, more useful product. These are (1) Establishing baselines (2) Ground behavior/performance assessments (3) Construction considerations (4) Use of the GBR during construction for establishing the baselines there are two considerable challenges. These would be to determine the condition of the ground that are needed to be baselined and how to quantify them. The goal of a GBR is to convert what the geotechnical engineers found into an easy to read product for...
In summary, to conclude this report by recommending that site visit is very useful and essential in college for the students of civil engineering, to make the student realize and understand the major very well and think about different parts and procedures of the construction by knowing the materials and its part in construction. In addition I would like to advice the students to take every opportunity during studies of structural materials is to visit sites during free time to explore more about the details and to understand it perfectly. I would like to mention to the college to keep on giving the students chances to visit more sites during the years of major in that case the encouragement will grow in the minds of students of civil engineering.
As a civil engineer, one must focus mainly on the design and implementation of transportation based structures such as bridges, roads, highways, airports and tunnels. Specifically, they focus on how to “plan and design transportation or hydraulic systems and structures, following construction and government standards, using design software and drawing tools” (www.job-descriptions.careerplanner.com). In order to ensure that the completed projects' reliability is up to par, civil engineers have to take into account environmental factors such as weather and apply their knowledge of geothermal physics. This career also requires individuals to have a solid background on chemistry, as the various materials used for construction each have their own unique...
In general, there are different types of procurement type for various situations, due to no one method can be suitable under the all different construction project. In this case, there are four procurement paths, which are traditional, design and build, management and design and manage, which will be advised to use. However, each method has different advantages and disadvantages. First, traditional path is the tender documents have been prepared and then invite the tender and the employer appoints the contractor to construct the project. There are several advantages of this traditional route in the construction industry.
The civil engineering field is about gathering and interpreting data, being able to give technical presentations to colleagues, team work to design and build a project, projects range from the design and construction of dams, bridges, buildings, roads, and water supply systems. In most cases the works of engineers are admired and sought after. Engineers play an important role in the development and improvement of a society. Yet, like other technical and non-engineering careers the civil engineers also face issues, for example, regarding ethics, high energy building consumption, increased soil and coastal erosion, inadequate water quality, traffic congestion, and some poor infrastructures resilience to disasters. Another example is that unfortunately in the United Kingdom, the civil engineering industry is highly fragmented with 93% of companies having 14 or fewer employees which is not always a great idea, as written by John Miles in Civil Engineering Informatics. There is also a need to implement new professional and educational approaches to new challenges and new implications that are needed for the twenty-first century society. This paper will introduce and explain five different issues that civil engineers are currently facing and elaborate about how these challenges interrelate to each other.
The students, who have keen interest in the study of civil engineering, should have sharp analytical and reasoning mind. They should also have good communication with their team members for the successful execution of the project. This s a professional program that deals with the designing, construction and maintenance of the bridges, roads, railways, buildings and so forth. A civil engineer is responsible for planning and designing of concrete structures and then executing the project at an estimated scale.
