The Brumadinho Dam Incident Abstract: This paper looks over the Brumadinho dam incident that occurred January 25th of 2019. Using resources from the Environmental Protection Agency, and an article from national geographic, it was identified that the dam was not only old and outdated, it was build using the upstream method. This method is known for being susceptible to vibrations, and with blast mining happening only a few miles away from the dam, it was bound to fail. The conclusion draw was that the failure could have been prevented by upgrading the dam to a more modern construction that was not rustable to vibration. While high in price up front, this could have prevented the major losses of life and money the company is now responsible for. Introduction: On January 25th of 2019 the Brumadinho Dam collapsed with a reported death toll of one hundred and seventy-seven and twenty-three non-fatal injuries. The dam, which was owned by Vale the same company responsible for another dam collapse in 2015, the Mariana dam disaster happened three years prior with a similar tailing design. The Brumadinho dam was constructed using the upstream method, which allows for a comparison with the regulations and recommendations for this construction method with the Environmental Protection Agency. With this comparison possible it is possible to answer the following questions; Was the failure of the dam similar with what would cause a failure in the Environmental Protection Agencies document? As well as, what actions should have been taken to prevent this catastrophe? Review of Literature: Though the investigation on this incident is still going on, with the death toll still coming in, there is plenty of information available to look into the causes of this catastrophe. “Built in 1976 by Ferteco Mineração, the dam used the upstream method, which, although common, is the least safe, according to experts” (Gabriel De Sá, 2019). Not only is this known as one of the least safe methods of constructing a dam, this was also one that was built forty-three years ago. This means that structural integrity was most likely compromised even farther due to just the age of the dam. In the same article De Sa wrote, it is mentioned that “Zhouri says upstream dams should be banned from mining in Brazil. “This technique is outdated and obsolete, used only in developing countries. It is not safe for the population, but it is the cheapest,” she says. “There are alternatives, such as dry containment, and Vale has this technology. The state must demand it. “We learned very little from Mariana’s tragedy. The rupture of the dam of Fundão should have been a huge alert,” says Ricas. “Costs shouldn’t justify avoidance of technical measures that guarantee the safety of the population, of biodiversity, and of the environment.” (Gabriel De Sá, 2019). From this there is an obvious issue of the company not wanting to spend the money and recourses upgrading methods that could have prevented and protected the people from this catastrophe. Not to mention that the company made a similar if not the same mistake three years briar with the Mariana dam failure. However, Vale released a press statement on January 29th that mentioned the decommissioning the rest of the upstream dams they own. “The plan presented to the Brazilian authorities aims to de-characterize these structures as tailings dams in order to reintegrate them into the environment. Vale currently has 10 dams built by the upstream method, all of which are currently inactive. All of Vale’s dams present stability reports issued by external, independent and internationally respected companies.” (Vale, 2019). The Environmental Protection Agency also has plenty of information on the upstream dam construction method, as well as information which can cause a failure. The Environmental Protection Agency notes that on an upstream method dam “…vibration of sufficient intensity and magnitude caused by blasting, trains, heavy trucks, etc., may cause liquefaction. The shear strength can be reduced to near zero such that the fluidized slimes easily burst through the remaining thin, unsaturated sand-dike shell and the dam collapses and flows.” (EPA, 94). This shows that the application of this mine is not meant for the use of mining, especially since the mining that was being done required large detonations that cause mass amounts of vibration. The method used may have been more affordable, however other methods would have been more stable. Methodology: This papers methodology is a research-based method, this paper looks at a news article over the incident to show an outside point of view. Then there is a professional look into by a document from the Environmental Protection Agency, this gave information on the type of dam and what the dam should be used for, and what could cause a failure of the dam. After these findings, the paper was able to come to a conclusion based on the knowledge gained from the news article and the Environmental Protection Agency’s documents about this type of dam. Conclusion: The conclusion found from the information provided by the Environmental Protection Agency, and the news article from national geographic is that this entire event, and the many who where killed was fully preventable. Not only did the company want to cut costs, they did not even think of upgrading a forty-three-year-old dam. The company also decided to blast mine by a dam that is susceptible to vibrations. So not only was the age a factor in the failure of this dam, but the process was sped up by the vibrations that most likely caused the liquification and failure of the dam. This is made worse by the fact that the company had another dam with a similar build, that also collapsed in a similar manner. The only good that came from the company was the decommissioning of the other dams with the same construction style. The best way to have prevented this catastrophe as a safety manager is to upgrade the dam by changing the construction type, while this may be expensive it would have prevented the major losses of the failure that occurred.

Contemporary Designed Landscapes: Chongae Canal Restoration Project

Contemporary Designed Landscapes: Chongae Canal Restoration Project. Chongae Canal Restoration Project This essay will examine the Chongae Canal restoration project. A social, political and environmental project. What was a polluted waterway later covered with elevated freeways is now a valuable urban park in a city lacking in green urban spaces (Green, 2010). The park’s celebration of cultural diversity appears to represent a vision of the district as one free of discrimination (Development Asia, 2019). That has the potential to propose meaningful public discourse around the community’s identity. The park was preferred for critical examination because of its distinctive narrative about community diversity, potential to influence cultural exchanges and a feeling of belonging (Nemes, 2019). When examining contemporary designed landscapes, Barbara Bender (2006) outlines how landscape is a subjective notion experienced and engaged with through human consciousness and active involvement. The similar place at the same moment will be experienced differently by different people (Bender, 2006). Landscape design has the ability to influence exchanges between people and the environment. A critical understanding of these exchanges has been informed by examining the social, environmental and aesthetic values that inform place making decisions (Meyer, 2008). These three distinctive components form part of any designed landscape in the public space of an urban environment. Urban spaces are able to provide distinctive social values as complex meeting points of diverse cultural and social exchanges (Taun, 1979). Mikyoung Kim Design won the international competition for Chongae Canal restoration project that aimed to highlight the reunification of North and South Korea. Kim’s design was a stone garden (Nemes, 2019). This involved the use of local stones sourced from the eight provinces of both North and South Korea to create an urban stone garden (Green, 2010). In the era of the optimistic “Sunshine Policy”, when South Korean leaders thought reunification with North Korea was imminent. The Chongae Canal project was to be the site of the reunification ceremony (Development Asia, 2019). Renewal and transformation are often associated with water offering a perfect setting to bring together the community in this beautiful public space (Meyer, 2008). The seven-mile-long Chongae Canal was once a river that collected water from surrounding mountains. Over the decades, it became a conduit for wastewater and raw sewage (Land8, 2109). By the early 1960s, the canal had become a symbol of poverty, and so dangerous that you couldn’t even touch the water. It was eventually covered over with an elevated highway dividing the city (Land8, 2109). The Seoul government took down the highway and decided to open up the river for public use. The design also eased the heat island effect, prevented flooding which used to be a major concern during Monsoon season and reduced air pollution (Development Asia, 2019). Its success can be measured by its popularity the canal has received since its opening in 2005 more than ten million visitors (Asla.org, 2019). According to Meyers (1997) symbolic forms, rich in associations, crystallize ideas and feelings which would otherwise escape definition; their existence enables individuals, whose own vague thoughts and feelings are otherwise unformulated, to participate in a collective ritual with others. Mikyoung Kim stone garden design visually expresses the level of the water. Water levels changes over the distinctive designed stones (Nemes, 2019). The stones design created a sloped plaza guided by the water levels at different times daily and throughout the year, allowing users to engage directly with it (Nemes, 2019). The design of the nine stones was to represent the nine provinces of Korea as a whole. The stone garden design is a cultural narrative which has the power to build a sense of community identity (Asla.org, 2019). Chongae Park has become an important space for community events and social interaction (Nemes, 2019). Successful public spaces have a design language and character all of their own, but can embrace different kind of activity and discovery (Taun, 1979). Landscape design has developed over time to become an art form of its own. Meyer (2008) believes that landscapes now are experienced rather than showcased, and that an urban environment’s form is equal to, if not exceeded by, the performance of its appearance. Elizabeth Meyer (1997) explains that landscape architectural history and theory should be about the cultural, geomorphological, and ecological history of the pre-existing site, as well as the history of both the design project and designer. The Chongae urban park was chosen for critical examination because of its distinctive narrative about community diversity, potential to influence cultural exchanges and a feeling of belonging. The beauty of the park’s visual identity is that it is a response to the idea that all cultures have a place in this park. Projecting the identity of the community in a visual way has created a spectacle out of what makes it unique, and given it a physical place to be celebrated (Meyer, 2008). This allows for emotional connection, meaning and understanding to address the diverse cultural, social and economic situations of the neighbourhood (Taun, 1979). These visual techniques are successful in creating varying intensities of sensory and spatial experience that address the diversity of needs and interests that the community would expect of an urban park (Jackson, 1994). As representations of culture, the objects are positive social influences, however it is the thoughts, discussions and behaviour that they would inspire in the community that are the constructive social outcomes to be encouraged (Jackson, 1994) . The restoration also has stimulated local economic growth. It is estimated that the Chongae project had a considerable economic benefit to the local economy (Development Asia, 2019). Soothing political issues, offering environmental benefits, and improving the population’s quality of life were the result of successful planning. Appendix Chongae Canal Restoration Project Figure 1.

Causes And Effects Of Delay In Malaysian Construction Construction Essay

assignment writing services In the construction industry, projects can be delayed among large number of causes. There are different type and categories of delays found on construction Projects. Delay has major effect on completion cost and time of construction Project. Delays can be minimized if they were identifying causes. Knowing the cause of any particular delay in a construction project would help avoiding the same. Even though with different types of studies have been carried out to identify the factors influence the causes of delays, since the problems are quite related to the studies need to focus on specific geographical area, or region in Malaysia. A major appreciation of the Malaysia construction industry is due to the growing rate of delays in project delivery. In Malaysia most public work projects, including any construction projects under government authority or under privacy are awarded on a competitive basis using the traditional approach. The consultants and contractors are engaged in separate contracts. The contractors commonly would be involved until the whole project have been completed 1.3 Aim and objective of study 1.3.1 Aim To investigate delays pertaining in construction projects in Malaysia 1.3.2 Objective To identify the major causes of delays in construction project; To identify the effects of delays in construction project; and To identify the methods of minimizing construction delays. 1.4 Background of the study Construction delay is major problems frequent occur in the construction industry. Delays adversely impact on project stakeholders including owners, design professionals, construction professionals, purchaser and others. The main objectives of construction projects are cost, time, quality and safety numerous According to Assaf, et al. (1995) “mentioned the most important causes in large building construction projects in Saudi Arabia which included approval of shop drawings, delays in payment to contractors and the resulting cash problems during construction, design changes, conflict in work schedules of subcontractors, slow decision making and executive bureaucracy in owner’s organizations, design errors, labor shortage and inadequate labor skill.” Refer to causes of delay in Saudi Arabia, the major parties to lead the delay happen which include client and contractor. Because of client always change the design of building. Besides that, late responds and poor project management team and also delay pay month payment to the contractor by client. On the other hand, contactor due to not enough worker during work progress and some argument with sub-contractor. According to Ogunlana, et al. (1996) “studied the delays in building project in Thailand, as an example of problem faced by the developing economies. They concluded that the problems of the construction industry in developing economies can be nested in three layers: problem of shortages or inadequacies in industry infrastructure, mainly supply of resources; problems caused by clients and consultants; and problems caused by incompetence of contractors.” Construction in Thailand because some parties fault due to project delay such as contractor consultant and. During construction stage the client because of changing certain part of design and lack of experience could not solve the problem immediately. Besides client, designer is one of the parties because of own fault which is give unclear drawing to the contractor due to lack in experience. On the hand, the other parties which is contractor because of facing in poor management team, improper planning and scheduling and also inadequacy of site inspection. According to Chan and Kumaraswamy (1996) “surveyed and classified the causes of construction delays in Hongkong as seen by clients, contractor and consultants, and examined the factors affecting productivity. The results of their research indicate that the five principal and common causes of delays are: poor site management and supervision; unforeseen ground condition; low speed of decision making involving all projects team; client initiated variations; and necessary variation of works.” Construction delay in Hongkong, the parties related to delay project include client, consultants, contractor and some relevant party. Factor to related delay by client such as client frequent delay make payment to contractor and also suffer in financial problem. Besides client, designer because of lack of experience always make mistake in drawing and late process design document. On the other hand, factor to cause contractor delay project which include lack of experience in project team and also poor site management and supervisions. Other than that, material is also one of the causes. During construction stages, material shortage and material changes to cause project delay. Identified the effects of delays in construction projects have been undertaken by some researchers. According to AIbinu and Jagboro (2002),”identified the six effects of delays were time overrun, cost overrun, dispute, arbitration, total abandonment, and litigation. The results of their studied about the effects of construction delays on project delivery in Nigerian construction industry, shows time overrun and cost overrun were the frequent effects of delays in construction projects.” In construction industry, the effect of project delay because of time and cost overrun. In this situation, some of the faults parties need to take responsibility to pay the loss and expense to those parties suffer in damage. Several studies have been studied and recommended the methods of minimizing delays in construction projects. Nguyen, et al (2004), “identified five critical success factors could be applied to reduce the effects of delays includes: competent project manager; adequate funding until project completion; multidisciplinary/competent project team; commitment to projects; and availability of resources.” To minimizing the project delay during the construction stage, first of all a client needs to hire an experience project manager. Once the problem of delay happen, the project manager can solve immediately. Besides that, the project team member should communicate with other team member. Aibinu and Jagboro (2002) in their study also identified two methods to reduce or if possible eliminate time overrun were acceleration of site activities, and contingency allowance. The contractor must take full responsibility during work progress. Once contractor found out actual work progress are not similar with estimate and he must take some action to avoid the project delay such as involve some additional worker. According to Odeh and Battaineh (2002) “recommended four methods includes: developing human resources in the construction industry through proper training and classification of craftsman; adopting a new approach to contract award procedure by giving less weight to prices and more weight to the capabilities and past performance of contractors; and adopting new approaches to contracting, such as design-build and construction management (CM) type of contracts.” 1.5 Scope of the Study The scope of the research will focus on literature review and a questionnaire. Projects investigate in this research included school building, church, office, hospital, communication facilities and etc. The survey will conduct in Malaysia. The questionnaire survey will design based on factors identify from literature review that contributed to causes of delays, effects of delays and methods to minimize delays. A questionnaire will developed to assess the perceptions of contractors and consultants of the relative importance of the causes and the effects of construction delays. The developed survey questionnaire will distributed to the target respondent in Malaysia. 1.6 Outline methodology Stage 1: Literature review The review of literature has provided useful information based on the causes, effects, reactions and possible solution related to the issues delay project in construction industries. Stage 2: Pilot study Data collection will take the form of a structured postal questionnaire. However, an initial pilot study will be conducted to test the validity of the questionnaire through in-depth interviews with three contract manager. Stage 3: Main survey questionnaire and questionnaire go through with interview. The feedback from the pilot study should assist in finalizing the questionnaire and prepare the ground for main survey. The questions with centre around the areas mentioned in the above objectives. In order to obtain a high level of response, a multi-option format will be designed and limited to about 30 question and 10 questions which are go through with interview. Open questions are considered to be inappropriate as they would required the respondents to formulate an answer which needs lengthier input and will therefore be more difficult to analyze. Stage 4: Analyzing the postal and interview questionnaire This stage is analysis of the questionnaire to determine the level of agreement or disagreement by the respondents to each question within the questionnaire by counting the number of respondents who answer favorably or unfavorably. Besides that, analyze the questions which is done by interview to determine how the contractor to solve the delaying problem of project. Stage 5: Writing the research report The stage involves writing up the content of the dissertation and should cover the chapter proposed in the following section. Proposed contents Chapter 1 – Introduction Chapter 2 – Literature review Chapter 3 – Research design and method of analysis Chapter 4: – Analysis of the result and discussion Chapter 5: – Conclusion and future study evidence

Question 1This week you will describe:Peak Experience (High Point)Many people report occasional “peak experiences.” These are generally moments or episodes in a person’s life in which he or she feels a sense of great uplifting, joy, excitement, contentment, or some other highly positive emotional experience. Indeed, these experiences vary widely. Some people report them to be associated with religious or mystical experience. Others find great joy or excitement in vigorous athletics, reading a good novel, artistic expression, or in love or friendship. A peak experience may be seen as a “high point” in your life story — a particular experience that stands out in your memory as something that is extremely positive. Please describe below in some detail a peak experience that you have experienced sometime in your life. Make sure that this is a particular and specific incident (e.g., happened at a particular time and in a particular place) rather than a general “time” or “period” in your life. Please write about exactly what happened, when it happened, who was involved, what you were thinking and feeling, why this event is significant, and what this event says about you and your personality.Include all of the following in your written description of the event:When did the event occur? (How old were you?)What exactly happened in the event?Who was involved in the event?What were you thinking, feeling, and wanting in the event?Why do you think that this is an important event in your life story?What does this event say about who you are, who you were, who you might be, and how you have developed over time?Basically you will see what kinds of characters, scenes, and themes come up in your life story.Question 2 this week you will also:Look for 3 educational resources on the internet that will help you make sense of your peak experience. Do some research online and find 3 resources that will help you understand your peak experience. These 3 resources can be: a website, a news story, a video, a free Coursera course, a podcast episode, etc. The 3 resources you find should add to what you learned from this week’s chapter.Explain how these resources helped you:understand why you do the things you dounderstand what you need most from your education and careerlearn to accept and celebrate yourself as you areknow exactly what you need from your relationships to feel accepted, understood, and fulfilleddiscover what you desire, more than anything else, from your lifegain the ability to ask for what you want and needget the ability to control your behavior the way you want and under any circumstancelearn what you want your life to add up to in the endYou are not trying to figure out if anything is wrong with you, and you are not trying to judge the “goodness” of your life. Instead, you want to decide whether educational resources from the internet related to psychology can help you make sense of the characters, scenes, and themes of your life story.
