The Hong Kong – Zhuhai – Macao Bridge (HZMB) Analysis

Introduction The Hong Kong – Zhuhai – Macao Bridge (HZMB) is a megaproject in South China and the longest man-made sea-crossing bridge in the world. Megaprojects are defined as ‘large-scale, complex ventures that typically cost a billion dollars or more, take many years to develop and build, involve multiple public and private stakeholders, are transformational, and impact millions of people’.[1] The HZMB is a 55-kilometer-long bridge-tunnel system situated at the waters of Lingdingyang on the Pearl River Estuary in southern China. Construction of the bridge began in December 2009 and the bridge was officially opened nine years after the construction first began. It is the link connecting the Hong Kong Special Administrative Region to the Macao Special Administrative Region and the Zhuhai Chinese mainland. This long link consists of three cable-stayed bridges, two artificial islands, an immersed tube tunnel with associated viaducts, relevant link roads, and the necessary boundary crossing facilities. This aspiring megaproject has overtaken the Stonecutters bridge in Hong Kong, previously the longest bridge in Hong Kong, becoming the longest bridge in Hong Kong and in the world. It was decades in the planning and cost billions, the actual need for this project was a big discussion point. It provides direct link between the east and west of the Pearl River Estuary and can facilitate the development of industries that rely on fast transportation, for example logistics, hence boosting the development of the three vibrant cities in the Pearl River Delta region economically and sustainably. Besides this there is the political ambition of China for HZMB to be a feat of human endeavour on a historic scale. Overview In this essay, I will talk about different sections of the bridge: Tuen Mun Western Bypass, Tuen Mun – Chek Lap Kok Link, the Hong Kong Boundary Crossing Facilities, Hong Kong Link Road and Hong Kong Link Road and Hong Kong – Zhuhai – Macao Bridge Main Bridge, deep diving on the Hong Kong Boundary Crossing Facilities. Tuen Mun Western Bypass (TMWB) The TMWB is a 9-kilometre double 2-lane expressway, consisting of twin tunnels, a toll plaza and associated administration buildings in Pillar Point. It links together the Tuen Mun – Chek Lap Kok Link and the Kong Sham Western Highway. Tuen Mun – Chek Lap Kok Link (TM-CLKL) The Tuen Mun – Chek Lap Kok Link is a 9.7-kilometre double 2-lane route between the between North Lantau and Tuen Mun South. It is divided into two main sections: Northern Connection and Southern Connection. The Northern Connection consists of a 5-kilometre long sub-sea tunnel deep under the seabed at a water head of above five bars crossing a reclamation area while the Southern Connection includes a 1.9-kilometre long land viaduct and a 1.6-kilometre long sea viaduct. Viaducts are a form of bridge interconnected in a series of small spans. They are used to connect two areas which are similar in height with the purpose of carrying road traffic whereas traditional bridges are constructed exclusively for crossing physical impediments. Hence, using viaducts over bridges are better as they connect the two land areas of similar heights and help reducing the traffic congestion to minimal. Friction bored piles are employed. The piles were designed as end-bearing piles and the top level of the pile caps are made from reinforced concrete structures. For the construction of the undersea tunnel, three Tunnel Boring Machines (TBM) were deployed: one with diameter of 17.6, which is currently the largest TBM in the world and two identical mix-shield TBMs with smaller diameter. A tunnel boring machine is a tube-like machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata. With the use of TBMs, a smooth tunnel wall can be produced, making them suitable to use in Hong Kong, a heavily urbanised area. Apart from boring the tunnels, TBMs also provide support. Selecting the TBM tunnelling as the method instead of the traditional Drill and Blast technique was in part due to lower environmental impact as TBM would create a much lower ground vibration than D

Please write the critiques from an international business perspective. This is for my international business class.DON’T USE OTHER SOURCES JUST USE THE CASES AND THE CRITIQUES SHOULD BE BASED ON THEM.The one page of your case critique must include your critiques on all three cases assigned to each lecture. This means that you don’t have to write a long memo on each case. I would like you to read each of three cases carefully and share your own ideas based upon your reading. It can be but not limited to why you think the case is well written or not, what aspects the case should have considered or included, and the like. I just would like you to read the cases carefully and critique based upon your understanding of the case.

Glendale Community College PI movie by Darren Aronofsky Discussion

essay writer Glendale Community College PI movie by Darren Aronofsky Discussion.

In this unit, we watched the gritty and, at times, disturbing movie Pi, by Darren Aronofsky. The story touches on science, religion, love, passion, and, of course, mathematics. Michael Drosnin has a theory that if the Biblical Text is put through a computer and letters are selected at certain regular intervals, a decoded message emerges that predicts the future. Skeptics observe that he keeps trying it until it appears to work. This is a modern sophistication of a hobby that Isaac Newton sometimes indulged in, finding mathematically hidden messages in the Bible.The number is G-d, the stock market, the future, or, apparently, anything else. When someone asks, “What does it all mean? What is the purpose of any of this?” this number is or contains the answer, to anyone who can understand it. It is the key to all, like the key described by the Talmud scholars that was lost to Jews when Romans burned their temples. The film seems to suggest that it’s better not to know the number, to forget it. This is essentially Sol’s advice throughout the movie: Forget the number! Live your life. Besides the ending, how does the movie convince us — if it does — of this theme that it’s better not to know and live in mystery? That is, how do the details of the movie — the script, the camera work, the details that may escape a casual observer — support this theme. Also, I have to ask, if you had the number and understood its secret, would you use it? If so, how? If not, why?Be sure to cite at least four details from the movie to substantiate your response, and show how each detail — sequentially and methodically — supports your idea.Intense scrutiny is not the same as sloppy writing. You should be economical in your writing — and deep and expansive. More words are not the same as more ideas. Remember to integrate quotations with good verbs and strong signal phrases.Observe MLA guidelines regarding in-text citation. Incorporate at least one idea — explaining whether you agree or disagree with it — from my lecture. Be sure to entertain more exploratory questions or personal connections, as I did throughout the lecture. Any connections to the random entry? Any analyses about camera techniques?Use deductive reasoning and inductive reasoning, each at least once, in your paragraphs. Place your deductive reasoning in bold and your inductive reasoning in italics.Avoid logical fallacies in your own writing, but feel free to point them out elsewhere.At the end of your post, show your deductive reasoning in the form of an equation, as I have done in my examples (i.e. Whale = large fish, large fish = scales, etc.).
