Building Information Modelling Analysis Construction Essay

Building Information Modelling Analysis Construction Essay Building Information Modelling (BIM) allows constructing a building virtually in a detailed form. During the design phase, the materials that will make up the finished structure including concrete slabs, rebar, steel structure, wall and ceiling components, HVAC, plumbing and electrical can be selected and placed. But tests can be carried out to ensure everything will come together without a glitch. The 3-D building model can be used to analyze the designed buildings energy efficiency by running scenarios to determine the best of possible solutions. In addition, depending on the detail of the model, you can automatically take off all items contained in the model and that way produce an impressively precise estimate. The software and database management technology exists today to accomplish exactly this. The degree of collaboration and coordination between the various construction disciplines that BIM calls for has to be bought into notice. Not only the owners and architects, but engin eers, contractors and, ideally, subcontractors as well, need to be involved in the project from the outset; in other words, during the design of the building. This, of course, invariably means some form of design-build rather than the currently prevailing design-bid-build process. BIM is an entirely new way of looking at the design and construction of a building. Many quarters are hailing BIM as the solution to most, if not all, construction industry ills, solving both design and construction problems while also providing a complete 3-D building model as a property management facility upon completion of the project. AN OVERVIEW The concepts and methodologies of BIM date back as far as 30 years-and then primarily within the manufacturing and aerospace industries. BIM as design and construction term was introduced about 15 years ago to set the then-emerging, information-rich, architectural computer-3-D modelling apart from traditional, and mainly paper-based, 2-D design and drawing. BIM intended to assign both software approach and method of designing and constructing a building by the use of highly coordinated and internally consistent computable information about the building; all the way from conceptual design, through construction, to post construction and asset management. A correctly assembled BIM is a reliable, digital, three dimensional, virtual representation of the project to be built, for use in design and in construction document production, scheduling, planning, performance predictions and in cost estimates. Three-dimensional demonstration of a centralized database containing all items that will consist of the actual building including their location, dimension, relation to other items, composition and cost in a digitally interpreted environment for engineers and architects. Assumption is done in such a way that all the input is accurate and resolves the builder in an easy assimilated view of the intact representation, its interrelations, and of any positional issues. And most importantly, it will also provide the information and the understanding necessary to resolve positional conflicts and other issues during the design phase, rather than later, on the building site. COMPONENTS OF BIM BIM is composed of several data involving legal, geospatial, financial, designer, owner/occupier, sustainers, Specifier and environmentalist data. Fig 1 Components of BIM Key features of BIM includes Ability to hasten design-to-build including starting projects from pre-approved project templates, supplier management and virtual commissioning designed to accelerate project execution. 3D visualization of the logical definition and the complete 3D physical definition, together in an environment to simulate and analyze equipment positioning and clash detection. Information management of all types of enterprise data including contracts, compliance documents, requirements, manufacturing processes, costing and procurement information. A global collaboration environment that enables full traceability, knowledge reuses and process automation for design, engineering and construction planning. Prepare the models for fabrication and construction with tools that support project work breakdown structure management including project status reports, task lists, approved vendor lists, workforce resources, etc. THE PLAYERS The field of BIM players breaks down into makers of three distinctly different sets of tools: 3-D modellers. Viewers/Surface modellers. Analyzers. The 3-D modeller is the true BIM tool, working with solid, parametric objects in sufficient detail to virtually construct the building. Not all views of the project have to be in that detail, however. The financing entity may want to see what the building will look like-as may the owner- and for that all you need is a surface modeller-or a viewer-to which all shapes are hollow. All it knows about is surfaces, which is all it needs to recognize in order to show concepts, and detect clashes for instance, and as such is of tremendous value. Analyzers are normally third-party software that speaks to the main BIM tool, meaning it can import and then analyze data from the 3-D modeller to determine the models energy efficiency or day lighting, among other things. BIM is an approach which essentially requires a technology to be implemented effectively. The combination of CAD, Object CAD and Parametric building modelling with respect to the effect and effort makes the building information modelling possible. Fig 2 shows the graphical representation of all these technologies which leads to BIM. Fig 2 Graph showing the technology The figure preceding shows the entire effect of each of these technologies shown in vertical axis measured against the effort required for those results in the horizontal axis. BIM has been consistent in the industry with its competitive advantages Increased speed of delivery Minimizes the errors Saves money Greater output High workability New revenue and business opportunity Design visualization Collision detection Quantity take-off 4D constructability 5D cost estimation Facility operations Fig 3 Hierarchy of BIM phases Building information modelling supports the continuous and immediate availability of project design scope, schedule, and cost information that is high quality, reliable, integrated, and fully coordinated. But it is not itself a technology, it is supported to varying degrees by different technologies. Building information modelling is based on intersection of 2 critical ideas: 1) Keeping critical design information in a digital form makes it very simple for updating and sharing .It is more valuable to the firms creating and using it. 2) Creating real-time, consistent relationships between digital design data using innovative parametric building modelling technology can save significant amounts of time and cost and increases the project productivity and quality. Below given is a detailed look at how Building Information modelling works and how the different phases such as design, construction and management of building lifecycle are benefitted. BENEFITS IN THE DESIGN PHASE During the course of a building project, an architect must handle the project scope, schedule, and cost evenly. Changes to any of these variables can have a negative effect on cost, time and money. Using the traditional methods, access to design and geometry related information is usually fairly steady. But cost and scheduling information is only occasionally available because of the period and attempt necessary to create it. By means of building information modelling, all of this significant information is immediately accessible, so that project-related decisions can be made more rapidly and effectively. Building information modelling allows changes to the project at anytime during the designing or documentation process without difficulty, thus the team gets more time to work on other high-value architectural problems. This leads the documentation and designing work of the building to be carried out simultaneously, instead of doing successively, this is due to the design plan is captured at the point of conception and embedded in the documentation as the work proceeds. Whenever a change is made to a project, all the consequences of that alteration are automatically coordinated throughout the project and is documented. This allows the design team to function faster, because this consumes the time and effort spent on delivering the visualisations and regulatory approval documents. The automatic coordination of changes offered by this building information modelling eradicates the coordination mistakes thus it improves the overall quality of the project and helps companies with more repe at business. BENEFITS IN THE CONSTRUCTION PHASE In the construction phase of the project lifecycle, building information modelling makes available the real-time informations on building quality, schedule, and cost. The builder can accelerate the quantification of the building for estimating and value-engineering purposes and for the production of updated estimates and construction planning. The cost and consequences of proposed products can be studied and understood easily thus the builder can prepare plans showing site use or renovation phasing for the owner. Building information modelling consumes less time and money is spent on administration process in construction because document quality is high and construction planning better. Thus the end result is that more of the owners construction money goes into the building than into overhead costs. BENEFITS IN THE MANAGEMENT PHASE Building information modelling also makes available the concurrent information in the management phase of the building such as performance of the building, its occupants and contents, and the economic aspects of the building. Building information modelling provides a digital record of renovations and improves more planning and management. It accelerates the alteration of standard building prototypes to site conditions for businesses, such as retail, that require the construction of similar buildings in many different locations. Physical information about the building, such as tenant or department assignments, furniture and equipment inventory, and financially important data about leasable areas and rental income or departmental cost allocations are all more easily managed and available. Reliable access to these types of information improves both revenue and cost management in the operation of the building. OPERATIONS AND MAINTENANCE BIM is updated during construction to create as build record. Geometry is linked with the text and tabular information in equipment and maintenance manuals and it becomes a record to support the facilities management. Fig 4 BIM model (L) and Prototype (R) Features of facility management Improved asset definition The allocation is done so as to include the cost and work order data with respect to the required time. Simplified order provision Improvements are to be made in allocating the time and cost data. Extended cost model It enables the costing of any product throughout the lifecycle which includes captured costs, budgets, estimates and cost roll up. Condition monitoring The condition data are to be captured by two different means namely instrumentation and visual inception. Request capture Additional captures for operations and maintenance works and also dealt with work order requests. Service life data It should include the management and service life capture; taking prior notice to perform the analysis using the standards. Environmental impact Sustainable working atmosphere must be given consideration for all the environmental data which allows the total impact assessment all the process. Permits The proper access, security and work must be done which is possible only by providing the permit captures. Operating and maintenance information Provisions must be given to analyse the operations and maintenance information as per the relevant standards. The above mentioned are the major features of the facility management which must be taken into account while the operations and maintenance sequence is carried out. CASE STUDY The below mentioned is significant case study carried out in BIM at Canary Wharf located at the Churchill place, London. This building is located in Churchill place, London. It comprises of around 30,000 m2 with expedient access to major facilities of Canary Wharf, Docklands Light Railway station Jubilee line. It consists of 4 basement level, ground and six trading floors. The concealment is characterized by steel and Granite mixtures. Depending from where we view the building appearance varies; from a point it appears as a steel building from another view it appears as a predominately stone building. Foremost goal of the designing is its sustainability level. Built on a Brownfield site, a BREEAM rating of Excellent was achieved for this building. Use of the IFC beam BIM models of the new and existing buildings where built by HOK and WSP using the software named Revit Architecture and Revit Structural correspondingly. Autodesk .RVT files where used for the purpose of all the data exchange in the entire project. By merging the supply chain steel fabrication model which was shaped using Stru CAD software by a Dutch steel fabricator was one of the momentous underscore. The project was further imported to the Revit using a 3D DWG format which therein relates the HOK produced a construction design. A high degree of significance was shown in all the results achieved using traditional non-BIM methods.   Design reviews have benefit from using 3D Revit and Navisworks review which is possible only through regular project meetings with client and design team.   The main contractor has modelled the services in 3D using CAD Duct and is coordinating all BIM models using Navisworks to coordinate the Services supply chain design.

Controversial Television Program Essay

My topic is Controversial Television Program; I believe that I can’t exclusively pertain to only one source. Why? Having a specific source restricts the information available for my topic that will hinder the comparisons of the advantages and disadvantages of certain controversial programs. A controversial television program doesn’t necessarily mean it has a â€Å"negative† impact to the audience, rather than a good conventional discussion for audience to tackle a particular issue that has a significant effect to the society or to an individual. It does not constraints ones idea, rather it asks us to become open minded and embrace various issues to talk about and open our minds and do something about it. This controversial television program varies from time to time. Decades ago, people are more conservative and restrict television programs that only cater to their taste, to their way of living. But now, people opt to have taste of these things that enhance their minds and argue things. I have chosen 3 various resources for my paper, and these three resources are great combinations to help me enable present a better research paper. These resources are in the same form of media as to my topic, and would surely cover all my questions and be able to expound a good argument to my audience.

Concretization

Concretization As with almost every aspect of â€Å"developed† or â€Å"first world† culture, a cloud of laziness accompanies any call to a challenge. Although finding an easier means of overcoming obstacles has been rooted in human existence since we came to roam the earth, it appears we have achieved a new level of indolence. Understanding abstract philosophical or religions bares no exception. To witness this one need look no further than todays pop culture. A quick Google search of â€Å"celebrity tattoos† yields upwards of 54 million results in a little over 2 tenths of a second.Riddled among the image results are countless crosses, Taijitu’s, words in Sanskrit and other philosophical or religious symbols. Riddled among these are famous rapper â€Å"lil wayne†, actress Angelina Jolie and pop celebrity Pamela Anderson. I do not necessarily condone assumptions, however, I believe it would be safe to say that these, among countless other, harbor s ymbols as an easy or careless means of professing a devotion to a specific ideology. Furthermore, an ideology that know little or nothing about.I may well be wrong and perhaps they are well educated in the ways of their respective religions/philosophies but would not wager on it if I were a betting man. Considering that Pamela is a vegan because her â€Å"†¦body is a temple† yet has had a not to distant history with pill and cocaine abuse might tilt the odds in my favor. Nevertheless, it is not just celebrities who are concretizing abstract and demanding philosophies, they are just most readily accessible.In todays first world countries, praising a concretized symbol of a philosophy or religion is an easy way of identifying ones self with the select group without difficulty of actually having to learn about it. Just as students are reading the spark notes instead of the book or parents are hiring au pairs instead of raising their children (working/single parents excluded ), so are most individuals taking a lackadaisical approach to their spiritual beliefs. This is easily done through making a symbol concrete.Consider the concept of yin-yang, a theory of balance representing male and female in unison to depict wholeness. This is often portrayed by the Taijitu symbol that most western cultures are familiar with. What is often difficult to understand about Yin-Yang is that it is ultimately a teaching of metaphysical dualism. This is to say that one is only as much itself as it is the absence of its counterpart; light is just the absence of darkness. The concept seems simple when applying it to light and dark but when it comes to questions of existence or consciousness it becomes difficult to understand.Consequently, people, either due to laziness or ignorance, attach themselves to the concrete symbol and the simplest explanation to accompany it. Thus we see that the Taijitu, in western culture, has itself adopted the name the Yin-Yang or more absurdly the â€Å"Ying- yang†. I have a friend who to this day thinks he has a tattoo Yin-Yang tattoo. It’s a pretty abstract and unlimited concept to fit in the confines of ones skin; I’m not sure if he even is aware of the word Taijitu; I don’t think I should ask. The development of concretization, however, cannot lay burden solely on the symbol.Symbols have been used to represent religions, philosophies and factions of all sorts for thousands of years. Instead, I believe ignorance, and furthermore the lack of motivation to rid oneself of ignorance, is to blame. This has become increasingly evident in the modernized world we live in today. In a time when information, entertainment and even food is mere seconds away at the fingertips of the majority of the nation, the concept of delayed gratification slowly slips through the proliferated cracks of our artificial society. I, too, am guilty of the act.When I went to military school in the 9th grade each cadet was responsible for two pairs of shoes, the dailies and the dress. The dailies were to have no scuff or tearing around the sole but would ultimately suffice with a rather dull finish. The dress shoes, on the other hand, were required to be shined to a mirror finish; a feet that requires the perpetual spit shine of rag and polish until the pores of the leather are filled. A rule of thumb is that one should be able to see the whites in their eyes when they pick up to inspect the shoe.After three hours work on one shoe alone, a blurred outline of my face was all I could make out. An older student heard me complaining to my roommate and came by to see what was the fuss. â€Å"I’ve been working on these all day,† I muttered, â€Å"this is impossible†. He smiled and turned as if to undermine my complaint. â€Å"Delayed gratification,† he replied as he walked off, â€Å"delayed gratification. † This was the first time I had heard the phrase. I looked it up an d have kept it in the back of my mind ever since. In this increasingly fast paced world we live in, instant gratification is phasing out the concept of hard work and reward.This holds true in our approach to religious/philosophical beliefs. We all want to just get it†¦ just understand†¦ just be enlightened. There are those that meditate for an hour, a day, a week and then are frustrated and perplexed as to why they are not yet enlightened†¦ Or, they go get Yin-Yang tattoo and claim they are. Unfortunately much of today’s world focuses on the simple, the easy and the instant and thus breed much of the laziness and ignorance that results in concretization of the abstract and complex.

The Legal Elements Of The Insanity Defense Essay - 1460 Words

Insanity Defense When learning about the legal elements of a crime, it is stated that in order to establish a crime was committed Actus Reus and Mens Rea must be shown. There is however, a default in this procedure. The Free Dictionary defines insanity as â€Å"Insanity a legal term for mental illness of such degree that the individual is not responsible for his or her acts.† This is one of many legal definitions of insanity, and as you can see a key part of this definition is â€Å"not responsible for his or her acts.† How can we then decipherer Mens Rea ? When making an insanity defense, you are making the argument that the defendant had no Mens Rea during the crime or even a persisting condition. This is where controversy begins, and many debates start to rise about the circumstances of using this as a defense. As studies continue, and more cases are brought out using the insanity defense the increase in demand for a consistent diagnosis is fast approaching. One of the many defaults with cases with this particular defense is, there is never one diagnosis, and different events lead up to other areas. There is only one repeating factor that all insanity defenses have in common, which is the lack of Mens Rea. The medical definition of insanity differs completely from the legal aspect. The medical definition of insanity is, as The Free Dictionary defines â€Å"a medically obsolete term for mental derangement or disorder.† There is no mention of criminal activity or lack of responsibilityShow MoreRelatedThe Defense Of The Insanity Defense1379 Words   |  6 Pages The insanity defense has been quite a controversial subject.
