Some of the roads and rail way will pass through the schools and residential areas, so it is important for government to install the noise barrier in critical spot especially near the schools areas, in order to reduce the noise pollution. The cost of installing the noise barrier is high but thousands of class will benefited from the noise barrier because the students can learn at school
This term is closely related to the noise because this is when the noise is considered a contaminant. Transportation, building construction and public works, industry, etc. are examples of factors that contribute to this pollution. 3.2 INTRODUCTION For years the noise has become a pollutant factor that affects people, but now is a serious problem with physiological, psychological, economic and social effects. Noise has existed since ancient times, but from the past century the problem of urban noise begins to appear, as a result of the Industrial Revolution, the development of new means of transport and the growth of cities.
Construction projects always are subjected to changes due to any factors in terms of scope of work, material quantities, design errors and unit rate changes. The changes on the construction project seem like an evil that makes the work delays, time overrun and also cost overrun. However, variation order does not really an evil but it is some necessary which is needed in construction projects. This report covers the introduction to the variation order in basic knowledge, causes and impacts of variation order towards construction projects. Besides that, the necessary of the variation orders in construction projects will also be discussed to understand the needs of variation orders.
Some of the difficult can be minor and easily resolved; some can be major and lead to dispute, with every new project fresh and slightly different problems developed. Which most of the challenges in construction project can be related back to ineffective communication, by ineffective communication we mean the failure of one
Which can create many consequences to the construction process. (For e.g., court stay order to stop the work). Fire is also an important factor. Fire accidents during construction may expect mostly by improper electric cables lining which further leads to unexpected
A) Introduction Noise pollution- “A form and level of environmental sound that is generally considered likely to annoy, distract or even harm other people.” Noise pollution has been an increasing worldwide issue, however, it is a tremendously destructive problem in our very own country. It causes stress related illnesses, sleep deprivation, hearing loss and distracts people. This issue can be proven damaging through the OR Tambo international. The OR Tambo International airport is situated on OR Tambo International Airport Rd, Kempton Park, Johannesburg. Airports worldwide generally deposit an enormous amount of noise pollution on daily basis due to the increasing demand for air travel.
NOISE POLLUTION: “Noise pollution refers to undesirable levels of noises caused by human activity that disrupt the standard of living in the affected area.” The source of most outdoor noise worldwide is mainly caused by machines and transportation systems usually. CAUSES OF NOISE POLLUTION: • Traffic noise • Aero planes noise • Concerts • Manufacturing plants • Railroad ADVERSE HEALTH EFFECTS OF NOISE POLLUTION: Noise pollution affects a person’s health which directly results in loss of hearing abilities. It also causes annoyance and a state of stress for the person who is tolerating a high frequency noise, no matter from what source it comes from. Hearing ability is defers with the passing of age, but if we face noise pollution at its most in a early age we might get deaf earlier. There are some images below which show noise pollution : 5.
Reaching their summer breeding grounds at the wrong time - even by a few days - may cause birds to miss out on maximum availability of vital resources such as food and nesting places (Press Association, 2016). These construction sites also cause pollution of the water with the emission from the machines. They excrete oil and the workers may toss garbage into the water if they are working near the coast or a lake. Marine life and aquatic creatures can choke on the garbage and can drown because of garbage getting caught in their gills. Now in many countries, they are trying to set up conservation sites to protect species that are endangered and most have laws against
