Construction Technology Design processes and Procedures

Construction Technology Design processes and Procedures The design process of a project can be very complex, there are multiple factors in which designers must take into consideration during the early stages of a project. Each factor plays an important role not only during the design process but they can also affect the life cycle of the project, therefore the RIBA plan of work is usually used which allows clear guidance on the roles of those involved and is easy to understand. Below is a brief description of the factors surrounding the Nottingham Jubilee Campus: Advanced Manufacturing Building Redevelopment project. Financial Finances are usually the first thing to consider on a new project as it can massively influence if the project is feasible or not. A budget is set in place and each stage of the design and production process is allocated an amount of money to keep within the budget. Running over budget can mean that the design may have to be adapted to keep the extra costs as low as possible which can affect the overall outcome of the project in terms of aesthetics and performance. Some projects can be funded by organisations that are involved or will benefit from the project, i.e. Local Authorities/Government, Stakeholders, Companies/Partnerships, residents and Students. Social A consideration must be made of the potential social impact of a proposed project, this can include: Impacts on residents The project should be designed so that minimal disruption is made both during the construction process and the operation of the project. Disruptive factors such as excessive noise and visual obtrusiveness will negatively impact the view of residents who will be affected by the project in their day to day lives. Environmental impacts The design should consider the local environment in which the building is to be placed. This can include higher pollution levels from increased traffic to and from the University Campus during the life cycle of the building and the impacts on local wildlife. Care should be taken to ensure that habitats that are removed are restored elsewhere so that the wildlife are not exposed to danger. It could also possible to design certain habitats into the project itself, through green roofs/walls and planted platforms. Economy Having an extension to a University Campus will provide a boost to the local economy. This can in turn lead to businesses expanding and providing more jobs to residents and potentially to the University Students. Client needs The Clients needs are incredibly important on a project, after all they are paying for everything. For a project, such as an extension to a University Campus, the clients needs will include: Fit for purpose classrooms The University has a duty to provide education to a high standard, providing classrooms that can achieve the high standards is essential. Security The safety of the students is the Universitys responsibility whilst on Campus, therefore having effective security measures in place is important. These security measures can include photo ID cards that allow access to the building through a card reader, security staff that patrol the premises and CCTV cameras. Energy efficiency There is a big focus on new buildings to be as environmentally friendly and sustainable through energy use due to the increased awareness of climate change. By providing ways in which energy efficiency can be increased, the running costs of the building will be lowered substantially throughout the lifecycle of the building. Legal Constraints The design of a building must comply with very strict Standards, Regulations and Laws. These practices are in place to ensure that any project is designed and built safely whilst providing construction guidelines. There may also be a contract in place which indicates what the client is receiving for their money.   Some of the legislations in place are: Building regulations Construction Design Management (CDM) Regulations British Safety Standards EN European Norm ISO International Standards Organisation Environmental There must be consideration for the environment during the design process of a project, the designers should not only consider environmental impacts during construction but also throughout the life cycle of the structure and eventually the demolition. Some aspects that should be considered are: Plant and machinery that is used on site to minimise pollution Materials: how they are manufactured, where they are sourced and the recycling possibilities Heat and power sources on site Water waste These factors should be considered to ensure that minimal impact is made on the local wildlife habitats and residents. There are multiple roles for numerous professions within the design team with each having a vital role. The roles and responsibilities for those involved are: Architect The architect is the person who initially designs the structure based on the clients needs/requests. There can be a group of Architects working together who are given a specific section/area to design if it is a large-scale project. Architects must ensure that the designs they create comply with the relevant regulations in terms of environmental, safety and the construction of the structure. An Architect will have a University Degree with relevant experience studying art.

Behavioral Phenotypes of Inbred Mouse Strains :: essays research papers

Molecular geneticists have recently been using targeted gene line mutations so as to effectively isolate certain genes as being the cause of a specific phenotype. However the effects of a gene can be a result of complex interactions within its genetic background. Scientist have tried to maintain and isogenic genetic background. However in choosing the appropriate isogenic background it is important that all of the effects of it be documented so that the appropriate selection of genetic background can be chosen for an expected phenotype and so that the results can be interpreted properly. The effects of different strains on the performance of various different tests of an animal’s behavior are documented here. A well established measure of mouse behavior is open field locomotion. In this measurement a mouse’s amount of movement, rate of movement and other behaviors are measured. These measurements are proposed to suggest specific levels of emotionality and anxiety in mice as well as other underlying traits. The levels of activity and anxiety have been measured for specific strains. The best choice for a strain when trying to assess the level of activity or anxiety for a mutation is the strain that is known to produce the opposite level of anxiety or activity. There are two types of learning tasks that have been assessed for. Complex learning tasks involve and animal using multiple pieces of information simultaneously and Avoidance tasks which involve the animal avoiding a location where they have previously received a shock. Other behavioral traits that have been assessed are aggressiveness, reproductive behavior and the effects of acoustic startle where the reaction of a mouse to a loud noise is measured as well as its reaction when the sound is preceded by a relatively quiet sound The effects of genetic strains have also been studied with regard to their effects on certain drugs. The effects of drugs such as ethanol show that it is very hard to generalize the effects of a specific drug on a specific strain since the reactions vary with the dose given and with the reinforcing effect that it has on the mice. In some studies it was shown that despite the noticeable mean effect of ethanol on a strain it did not have the same effect with a different dose. However certain generalizations of strains sensitivity to ethanol have shown themselves to be robust across several procedural variations.

Cultural and Political Changes and Continuities in Rome Essay

Rome throughout history is often thought of as rather homogeneous—ancient artifacts timeless, always the same emphases. But, while there were continuities, there were also changes of different sorts in various time periods. Specifically, cultural and political changes in the Roman civilization between 100 ­600 CE, the late classical era, included the rise of Christianity and the division of the empire into two halves, while a continuity was the use of Latin and Greek as common languages. The first change, Christianity spreading throughout the civilization, is shown in the development and spread of Greek Orthodox and Roman Catholic lifestyles. Constantine legalized Christianity in the fourth century AD, and soon after, Theodosius made it the empire’s official religion. All other religions in the empire began to fade away, becoming â€Å"discouraged† at best. This was all due to the Christian missionaries who travelled the region. After this, as a result, a new controversy arose: the classic one of the separation of church and state. The unified Christian lifestyle was very different from the previously religiously ­tolerant classical Roman Empire. The next change is that the empire soon split in half. Rome became simply too large to govern under one governmental body, and so split into the Eastern and Western halves in 284. These two had separate governments and separate religions (Greek Orthodox and Roman Catholicism respectively). Also, the halves were relatively independent from each other, fighting their own battles and having different levels of advancement in science, technology, and  more. This was different from the united empire of older times. The separation of the halves would eventually create many controversies in the future, especially whether or not they were to aid one another in battle. A continuity of the time period, however, was the use of the common languages Latin and Greek. Latin was known as the original trademark of the Roman Empire and is still associated with it today. (This is similar to the Chinese language of—where else?—China.) Greek came a bit later, with the spread of Christianity, and became a favorite of scholars and politicians. It was originally spread by Alexander the Great. However, all citizens still needed to know Latin to be able to communicate commonly throughout the empire. Both of these languages were used throughout this time period and this use remained a continuity for the Roman civilization. In conclusion, the cultural and political changes in the Roman Empire between 100 ­600 CE (late classical era) involved the rise of Christianity and the division of the empire. A continuity was the widespread use of Latin and Greek. These changes and continuities would affect global perception of the Roman Empire for many centuries to come.

Singapore As A Financial And Transportation Hub And A...

Introduction: Singapore, located in Southeast Asia, has a population of 5.39 million people. It’s land area stretches to 716.1 km2, with a high population density of 7615 per km2 (World Bank, n.d.). Singapore serves as a financial and transportation hub and a global commerce. Its economy is known for being the free, innovative, competitive, and business-friendly. It integrated itself in many economic sectors including financial services (fourth-leading financial centre), manufacturing, oil-refining (third-largest oil-refining centre). By the end of the 20th century, Singapore has shifted from a setting up a nation-state into a developed and global city. The city built a competitive economy through the influx of migration (Armaldas, 2009). In fact, Singapore was ranked, right after London and New York, as the third most competitive city in the world by the Economist Intelligence Unit’s Global City Competitive Index. The qualification was based on 8 different categories that shaped a competitive city; from the 8, Singapore ranked number one in ‘financial maturity’ and ‘physical capital’ (Yew, 2014). Due to the continuing competitiveness between Singapore and the neighboring cities and countries, including China and India, the Singaporean government has been working and reconstructing their economic foundation to hold on to its title ‘East Asia’s primary hub’ (Armaldas, 2009).
