Building Information Modelling (BIM)

Building Information Modelling (BIM) 2.1 Introduction As expressed in the Egan report (1998), the UK construction industry is a significant contributor to the domestic economy in the UK that it is simply too important to be overlooked. The construction process and its success are influenced by various factors and choosing the most effective investment to improve the construction process is a very important decision. Building Information Modelling has been said to represent a paradigm that will have comprehensive benefits brought to the construction industry (Eastman, 2009b). Popov et al. (2010) claimed that the growing diversity of disciplines, professionals, tasks, events in respect of the management during design and construction stages of projects, plus the more competitive cost and more intense deadlines with higher quality expectations as well as the need for enhancing technology are the driving force of information modelling in the construction industry. Building Information Modelling, or better known as BIM is not; strictly speaking a new technology as it has been developing and used by other industry sectors since 1950s i.e. the automotive and aero plane industries. These industries have been way ahead of the AEC industry as for the past 20 years, fully utilizing the available technology for their industries (Augustsson, 2007). Subsequently, this literature review will assess and evaluate the historic and current information in respect of Building Information Modelling to enable an understanding on the past development of BIM, the benefits that it could offer to our construction projects as well as identifying the barriers entailing for the full adoption of BIM among the contractors in the UK construction industry. 2.2 What is BIM? As defined by BIMForum:- â€Å"A building information model (BIM) is an object-oriented building development tool that utilizes 5-D modeling concepts, information technology and software interoperability to design, construct and operate a building project, as well as communicate its details† (BIMForum, 2007). One common understanding to describe BIM is the building development tool that creates a three dimensional (3D) geometric model with computer softwares. The model then can be used to assist the design, construction and operational process and also acting as a communication tool (BIMForum 2007). Nevertheless a 3D geometric model wouldnt be sufficient to answer the demanding construction requirements at present. A BIM model contains a high level of intelligence which not just limited to a three-dimensional geometric representation of the building, (GSA, 2007) but also includes 5D modelling where the 4th dimension is referring to time element whilst the 5th dimension is referring to cost. In addition, as indicated by BIMForum (2007), there might be further development that is inclusive of procurement application which is the 6D as well as the operational applications which is the 7D. In general, a building information model is a digital representation, â€Å"virtual† representati on of all the physical and functional characteristic of a building which also acts as a resource of information storage for the building which could be shared/used from the inception period and throughout the lifecycle of the building. 2.3 The past development and revolution of BIM Conventionally, constructing a building was merely the responsibility of the Architects and the Engineers, designing on papers and then the Contractors build it. Cyon Research (2003) stated that Construction projects have always been defined by various drawings and documents where at times might be in conflict with each other thus showing inconsistency. These inconsistencies are the typical issues that often aroused when the documents and drawings are maintained separately with different participants working on different or superseded documents. There will always be unanticipated field costs, delays and eventual lawsuits between various parties within a project team as a result of errors and omissions in paper based communication. According to Vinod Kumar (2009), the beginning of orthographic drawings and perspectives can be traced back as far as during the Renaissance era when Filippo Brunelleschi represented the plans in drawing format for Santa Maria del Fiore in Italy in order for the patrons to understand how the building would look like. Vinod Kumar (2009) further explains the evolution of systematic documentation from manual methods all the way till our presently available technology by dividing it into three phases: I phase Till early 1980s: Before 1980s the traditional way of creating design documents are through manually drawn lines representing building i.e. plans, sections, elevations and etc. II phase 1980s to Late 1990s: This was the period where major change took place from manual drafting towards computer aided drafting when computers were firstly introduce. There is more elaborated information as the complexity of buildings increased as well as more specialization in the design and construction process. Use of computers, especially for 2D drawings and reports are ground-breaking changes into the systematic Documentation. III phase Beginning of the 2K: With the buildings degree of complexity presently, the number of parties involved in the process of drawing production has also increased. In line with the development of technology there are also more introduction of more interrelated and integrated building system i.e. HVAC system, energy requirement and etc. The computer based technology has also been constantly updated to reduce errors that occur but nonetheless they are still merely the collections of manually created, non-intelligent lines and text. The diagram below shows the evolution from manual methods all the way till the introduction of new technologies. A previous study by Autodesk (2002) which correlates with Vinods statement, mentioned that in the early 1980s the Construction industry took one step forward when the architects began using PC based Computer Aided Design, CAD. It is said that the CAD system was adapted with ease by the Industry as it was initiated from the pin-bar drafting which the Industry was familiar with. Thus many construction documents and drawings were completed using CADD rather than being drafted manually on drawing boards. DWS files were then exchanged in replacement of paper drawings, from simple graphics to the information content on the building. The CAD files developed significantly, communicating the information on the building which plotted drawing couldnt. Following that Holzer (2009) also stated that in the late 70s and early 80s, CAD systems like RUCAPS was used where it operated in parametric environment enabling 2D information extracted from a 3D model. RUCAPS allowed multi user access and put f orward a new way in generating, distributing as well as retrieving building information which was different fromt he common drafting processes. Unfortunately the down side of this system was the high cost and slow speed of the system as well as its inability of producing more complex geometrical shapes. Nevertheless, some of the fundamental concept of RUCAPS can be found in the current BIM software such as Autodesks REVIT, Bentleys TRIFORMA, Gehry Techs DIGITAL PROJECT and etc. Nowadays, the use of BIM is very common within the manufacturing and aerospace industries where new products or product changes are modelled virtually for the assessment of design, performance and production. . We are also in the process of experiencing a similar revolution in the construction industry. BIM and other related technologies have emerged since the past decade and developing up till the present where they have been acknowledge as the platform for the design and construction of various projects (Shen, et.al, 2009). Nevertheless, FWCI (2009) argued that it is important to understand that BIM is not CAD+ or the â€Å"Son† of CAD as BIM functions in its own approach and discipline. BIM, acting as a single source entry for project team involves the process of generating, storing, managing, exchanging and sharing building information in an interoperable and reusable way. Generally a BIM system is a tool that enables users to integrate and reuse building information and domain knowledge through the lifecycle of a building Presently there are numerous BIM products on the market by various vendors. Autodesk Revit was considered as one of the leading BIM creation tools. Bentley Systems, Graphisoft, Vico software and Nementcheck are also currently very well-known in the market. They each provide various building model tools to design a building (Rosenberg 2006). With this technology, the information needed for a projects design, construction and operation are contained in a model digitally which is centralized and could be shared across all associated project stakeholders (COBRA, 2008). 2.4 Various understanding of BIM in the Industry At present there is a vast amount of information that is available in respect to the definition of premise of BIM. Holzer (2007) explained that even though the application of BIM becomes more accepted and common throughout the industry, but there has been a problem in agreeing the definition of BIM. The common definitions would be described as a method for project information management with the combination of non-geometry attributes with geometrical entities, or defined mostly by pointing out its capabilities for cost-control and to facilities management. Holzer (2007) continues to claim that because the term BIM is often used by vendors for their marketing strategies in order to promote their company software, the definition of BIM technology has become very confusing. On the other hand, Eastman et al (2008) has suggested that in order to deal with this confusion it is useful to describe modelling solutions that do not utilize BIM technology. This includes tools that create models containing only 3D data with no object attributes, models that do not utilize parametric intelligence, models composed of multiple 2D CAD reference files that must be combined to define the building as well as models that allow changes to dimensions in one view that are not automatically reflected in other views. Furthermore, another popular â€Å"talk about† issue within the industry is the multi dimension product models, the ability of BIM to provide multi dimensional application. (GSA 2007) has stated that 4D models represent 3D models plus time which include project phasing, construction scheduling whilst 5D models incorporate the costs elements. Nonetheless, Lee (2005) has identified the additional numbering of the dimension as â€Å"nD† modelling. Lee stated that nD modelling is an extension of the building information model that incorporates multi-aspects of design information required at each stage of the lifecycle of a building facility. On the other hand, in the year 2006, The Associated General Contractors of America (AGC) also published â€Å"The Contractors Guide to BIM† which touched on the issue in respect of the continuing usage of the numbering i.e. 6D, 7D, and etc has therefore acknowledged the extended application of the 3D tool as â€Å"XD† (AGC , 2006). This research is mainly focusing on the 3D models with incorporation of time (4D) and cost (5D) elements. 2.5 Benefits of BIM There are many obvious benefits that BIM could offer to various parties including the owners, planners, engineers, estimators, designers and etc. It is understood that different stakeholders would value BIM differently. They may share the same information but have different responsibilities and uses on the model. From a Contractors perspective, BIM brings essential value for enabling virtual construction of the structure within a single source file (Hardin, 2009). As quoted from the BIM 2009 Smart Report, â€Å"A model is Worth a Thousand Drawings†. Contractors are making use of the intelligent model for assisting them with various activities i.e. planning construction sequences, cost estimations and bidding, conflict resolution and visualization project demonstration for client and etc (Neeley, 2010). The incorporation of intelligent data improves the models construction and post-construction realities, which also enables the contractor to get closer to the world of the desig ner (Sage software 2008). The initial literature review has showed that costs are significantly reduced, time is saved and the quality improved. 2.5.1 Single source Model In conventional process, the Project Manager reviews the updated drawings and reflects any changes onto the schedule as the design progress. Many times the same information is entered into different program. Every repetition increases the probability of inconsistency and error occurrence. BIM on the other hand allow direct changes applied to the single model. As both designers and contractors have access to the model simultaneously, this corresponding process also enables them to reduce lead times which normally take place throughout the period of sending back-and-forth the documents. The collaborative environment contributes to a substantial time saving during pre construction. Extra coordination checks are also unnecessary because the information generated from the model will lead to fewer errors on site which normally is caused by inaccurate and uncoordinated information. In the case of any last minute design changes, addendums, clarifications and etc it could be altered and updat ed to the model automatically across the project team, from early design through completion (Hardin, 2009). These ensure that all parties are working with the latest information. With all the information contained within the BIM database it will definitely increase the efficiency between the Architect, Engineer as well as the Contractors. 2.5.2 The 3D Visualization Clash Detection The 3D visualisation capability of BIM models can be of great benefit as a means of testifying the workability and demonstrating aspects of the construction itself such as construction sequencing, logistics, access, storage and security (C3 System 2009). BIM allows for â€Å"building twice† which offers various benefits like improvement in Constructability, maintainability, cost estimate accuracy and etc. This reduces ambiguities before commencement of actual construction (Robert, 2005). The construction issues for layperson or non layperson are also made easier to understand as the 3D visualisation helps them to understand any constraints that the client had not made clear earlier, or were misunderstood (Furneaux and Kivits 2008). One of the major benefits which BIM could provide for contractors is clash detection. As identified by FWIC (2009), a hard clash is where more than one object is being designed to occupy the same space whilst a soft clash is where the objects in the design is too close to each other that there is no space for access or construction, or are too close that they have violated the building codes. The BIM system automatically detects and manages interferences which prevent possible delay or additional cost. The system could be set to run the check either the entire model or between certain parts of the model. 2.5.3 Construction Phasing (4D Simulation) Furthermore, one of the obvious BIM applications for improved time efficiency is construction planning. Hardin (2008) argued that the construction planning is one of the most important tasks and also one of the driving factors that determine the success of any projects. It is noted by Eastman et al (2008b) that Construction Planning and scheduling involves sequencing activities in space and time, procurement consideration, resources, spatial restrictions and etc. BIM is said to contribute in project planning solutions via the use of 4D simulation. Napier (2009) claimed that the conventional scheduling methods are labour intensive and is not easily understood by laypersons. BIM enables better communication and understanding how the schedule would impact site logistics as a result of the 4D construction phasing/planning tools that incorporate direct links to the design model, capturing spatial information which the traditional Gantt chart is unable to demonstrate. The 4D model incorpor ates time as added 4th dimension which enables the planner to visually plan and sequencing of construction activities with space and time consideration. Also, there might be specific materials and products selected from a potential range of refinements and substitutions that meet the project specification but may result in changes to some aspects of the design. As Neeley (2010) have stated, with the allowance of â€Å"what ifs†, a significant of cost, project risks and unnecessary waste could be saved by shifting the â€Å"try-and-error† process from construction site to the virtual environment on beforehand. Resource Allocation/Reducing Waste According to Egan (1998) in â€Å"Rethinking Construction†, within the construction industry almost 10% of materials are wasted and 30% of construction is rework. As mentioned by Articlesbased (2009) construction projects are very often planned based on resources availability as well as other external factors. With the 4D construction phasing/planning, the team members are able to understand the scope of work and the availability of various resources in order to optimize the resources and labour accordingly. In addition, Eastman (2008b) highlights that BIM is also accurate in providing the design model and material resources required for each segment of the work, it effectively assists in utilization of critical resources like labour, material and time during the building construction life cycle. With the improved monitoring of site logistics and the progress of project, the site management via BIM fosters just-in-time (JIT) of materials, plant/equipment and labours. Pre-fabrication Accuracy of design details are critical for determining the success of pre-fabrication, and a data-rich BIM model can have a positive impact and provide greater confidence on pre-fabrication. As BIM brings clarity towards a complex project, more contractors appreciate that BIM offers the advantage of effective coordination as the complexity level of project increases. The â€Å"Design to Build and Build to Design† concept improves accuracy for estimation and design specification for prefabricated elements thus reducing unnecessary wastage (BIMJOURNAL 2009). With greater confidence in the coordination process, many contractors are approaching more prefabrication options to help ease schedules. (BIM Smart Report, 2009) 2.5.4 Cost Estimates/schedule management From the costing aspect, Jernigan (2008) stated one of the main benefits provided by BIM is the accuracy in cost estimate during earlier stages. Conventionally, estimators have been relying on Excel spreadsheet to carry out their construction cost estimating (Autodesk, 2007), Eastman (2009b) then revealed that BIM include features for extraction and quantification of BIM component properties. By using a building information model instead of drawings; the takeoffs, counts, and measurements can be generated directly from the underlying model and the information can be linked to generate bills of materials, size and area estimations along with other related estimating information. Therefore the information is always consistent with the design and reduces the potential for human error or misunderstanding (Autodesk, 2007). This contributes to substantial time and cost saving as well as ensuring good quality of the BOQ. BIM offers the opportunity to develop more accurate cost estimates bas ed on actual elements (Hartman and Fischer 2008). Moreover, the linked cost information evolves in step with the design changes (Ashcraft, 2008). In addition, an indirect advantage that BIM could offered is the estimator would be given more extra time to bring in more value engineering, more time for risk evaluation and to more time to find any additional cost savings as the â€Å"technology† has taken up most of the grunt work from the estimator (Hague, No date).Using cost attributing features of the model to assess alternative design and construction schemes to enhance and improve the value engineering process; BIM certainly contributes in supporting the Contractor to present value for money to the Client. Neeley (2010) has claimed that the use of BIM and IPD (Integrated Project Delivery) is reducing project costs around 10%- 20% below construction costs compared to non BIM/IPD projects. 2.6 Case Studies No 1: One Island East, Hong Kong One of the popular examples of the actual Building Information Modeling Project that has been mentioned by various Authors in their research is One Island East Office Tower in Hong Kong which was developed by Swire Properties Limited. Together with the project BIM consultant, Gehry Technologies (GT) they began the process of working together to create a single, 3D electronic Building Information Model (Riese, 2006). The Project Details are summarized as follow: 2.6.1 Background Information The One Island East is a 308 meter high skyscraper with 59 stories of office space and two basement levels. The building has 70 floors in total which comprise of a sky lobby on 37th and 38th floors (Elkem Microsilika, 2009). It was Swires intention to achieve a high-quality design while improving construction time as well as cost savings by the use of collaborative, collocated work methods and integrated 3-D modeling tools. The initial objective was to save 10 percent on the cost with reduced time for construction (Shelden et al, 2008). The software tool chosen to create the BIM for this project is â€Å"Digital Project† with some of the benefits stated as follows: (Riese, 2006) Has automated clash detection and management Has a complete ME system routing tool. With built-in scripting function, enabling project requirements to be integrated for customization. Automated simultaneous file versioning and file sharing. Able to handle and manipulate large amounts of data Integrated with Primavera scheduling software with high interoperability 2.6.2 BIM Implementation (Pre-tender stage) BIM commenced after the schematic design phase. The office building has been pre-designed virtually using Digital Project by assembling up to 300.000 building components in a single master file. Almost all coordination issues were resolved using BIM. The design team, BIM consultant and Project Manager worked in one room for the first year. They also communicate with each other via a portal site for the BIM process. The DP software was capable of identifying geometric clashes and generates a list automatically. There were already several clashes and errors identified and resolved before tendering and construction. The DP tool also measured most of the quantities automatically which reduced the time and effort compared to manual take off. Also, the quantities were linked to the BIM which automatically updates when changes were made. 2.6.3 BIM Implementation (Tendering Stage) The model was provided to all tenderers which enabled them to have confirmation on the bill of quantities using the model without having to measure the quantities manually. As a result, tender process improved significantly with lower cost estimates and more accurate quantity takeoffs. 2.6.4 BIM Implementation (Post Tender Stage) Gammon Construction Limited, which was the contractor awarded for the project had full responsibility for the BIM model and began the development of highly accurate and detailed 3D BIM model for construction, ensuring that all 2D information would be firstly scrutinize in the 3D prototype before it went to the site. 2.6.5 BIM Implementation (Construction) During the construction period, the BIM model became the main visualization tool for the coordination of various project elements. There were full time modelers that assisted with the clashes identification and coordination issues where the design solutions were then incorporated into the model. A few subcontractors also participated in modeling their parts of work. 4D simulation was one of the main factors for the success of the OIE project. It was used extensively for improving construction sequence and managing risk. 2.6.6 Outcome There were more than 2000 clashes and errors were identified prior to bidding and construction stage, which resulted significant cost savings. The figure below is an example of a clash that has been detected between an electrical cable tra y and an air supply duct. Without BIM it wouldnt have been detected until the actual construction taken place which might potentially cause additional cost and time to the project. According to Shen et al.(2009), the geometric coordination off the design prior to construction is thought to achieve 10% cost savings whilst construction process modeling is thought to contribute further 20% cost savings on the construction. Gammon Construction has also reported that Construction Process Modeling saved the project at least 20 days. This project was awarded the American Institute of Architects 2008 BIM award for design/delivery process innovation. 2.7 Implementing BIM and the Potential Challenges From section 2.2 above it is demonstrated that BIM has brought numerous advantages and benefits to the industry. However there are also challenges and barriers that to be overcome before the full capability of BIM could be demonstrated and subsequently fully â€Å"enjoyed† by the industry stakeholders (Furneaux and Kivits 2008). In the very traditional and fragmented building industry, new technologies are not easily introduced. It should be noted that when a new technology is introduced, there will be a certain period of time in which the claims about the potential of the technology needs to be examined, tested and verified particularly the AEC industry which is known for the very long adoption periods of promising technologies (May et al. 2005; Salazar et al. 2006). Even though the technology of BIM is readily available and rapidly maturing but the adoption of BIM is much slower than anticipated (Fischer Kunz, 2006). Gillis (2008) made the criticism indicating that UK appears to be a more conservative and over protective country that demands proven effectiveness before considering adoption of new technology whilst Counties such as Norway, Sweden, and US attempts to proceed with new technology without 100% confirmation (Simon Gillis, 2008). As criticised by Prather (2007), most of the time, our professional would take the â€Å"wait-and-see† approach towards BIM. This is echoed by Safe software (2008) stating that our industry would mostly accept BIM only when the risk level has dropped and a clear return on investment is made known to the industry. Moreover, in these recessionary times, the money to spend on technology has got to have a good business case. The current UK industry inhibitors include contracts that has not promote working in collaboration, no external incentive for innovation, no motivation for parties to seek ways to deliver a better or quicker product and etc (Steve Dunwell, 2008). 2.7.1 Installation and operation Cost Eastman (2009) has highlighted one of the barriers to adopting BIM is the cost associated with the implementation. It is said that implementing new technology like BIM requires additional cost in respect of purchasing new software and hardware packages, training as well as changing the work processes and workflows. Also, if there are no technical expertises available within the organization, there will be a need to engage with external consultants to train employees prior to applying BIM within the organization which accounts for additional cost as well (Furneaux and Kivits 2008). Corresponding to what Eastman (2009) as well as Furneaux Kivits (2008) have said, a research done by Suermann et al. (2009) revealed that the whole installation of BIM for an organization is a costly plan when done at on one occasion, and even greater when done for several installations simultaneously for different projects. In addition, Suermann et al (2009) findings showed that there has been company which have had to increase their effort and cost allowance to do BIM due to the high learning curve. Apart from that, there is also an implication for procurement policy where consideration needs to be given to the additional funding for the development of BIM models in the first instance. The large size of BIM files will involve a different system for data sharing i.e. real time access to the BIM database between firms which are geographically distant and high speed internet connectivity will be essential (Kiviniemi et al., 2008 p.64). This would constitute extra cost for the operation of BIM. Furthermore, in order to reduce the risk of data corruption, sabotage, and loss; it is important to pay any indispensable cost associated to ensure data stability and security. 2.7.2 Embracing BIM throughout the entire supply chain Another apparent factor that has caused BIM taking the back seat is lack of commitment from the higher level of the supply chain. According to Oberle (2009), the transition to BIM requires support and commitment throughout the supply chain from top to down of an organization. In addition, The Crawley Schools PFI project in West Sussex has revealed the benefits which they have gained with the implementation of BIM but simultaneously also addressed one of their main barriers in implementing BIM was the reluctance of the supply chain in embracing this new technology, stating that some conservative individuals did not believe the benefits that BIM could offer thus were hesitant to undertake this new approach (Constructing Excellence, 2010). It is also noted that some Contractors that have too much existing workload might give the excuse that they dont have enough time to try out new technology. As quoted from Dunwell (2009), â€Å"Old habits die hard†. Most workers are reluctant to step out from their comfort zone and believed that their current handling approaches towards Building Information Modelling (BIM) Building Information Modelling (BIM) 2.1 Introduction As expressed in the Egan report (1998), the UK construction industry is a significant contributor to the domestic economy in the UK that it is simply too important to be overlooked.

The common definitions would be described as a method for project information management with the combination of non-geometry attributes with geometrical entities, or defined mostly by pointing out its capabilities for cost-control and to facilities management. Holzer (2007) continues to claim that because the term BIM is often used by vendors for their marketing strategies in order to promote their company software, the definition of BIM technology has become very confusing. On the other hand, Eastman et al (2008) has suggested that in order to deal with this confusion it is useful to describe modelling solutions that do not utilize BIM technology. This includes tools that create models containing only 3D data with no object attributes, models that do not utilize parametric intelligence, models composed of multiple 2D CAD reference files that must be combined to define the building as well as models that allow changes to dimensions in one view that are not automatically reflected in other views. Furthermore, another popular â€Å"talk about† issue within the industry is the multi dimension product models, the ability of BIM to provide multi dimensional application. (GSA 2007) has stated that 4D models represent 3D models plus time which include project phasing, construction scheduling whilst 5D models incorporate the costs elements. Nonetheless, Lee (2005) has identified the additional numbering of the dimension as â€Å"nD† modelling. Lee stated that nD modelling is an extension of the building information model that incorporates multi-aspects of design information required at each stage of the lifecycle of a building facility. On the other hand, in the year 2006, The Associated General Contractors of America (AGC) also published â€Å"The Contractors Guide to BIM† which touched on the issue in respect of the continuing usage of the numbering i.e. 6D, 7D, and etc has therefore acknowledged the extended application of the 3D tool as â€Å"XD† (AGC , 2006). This research is mainly focusing on the 3D models with incorporation of time (4D) and cost (5D) elements. 2.5 Benefits of BIM There are many obvious benefits that BIM could offer to various parties including the owners, planners, engineers, estimators, designers and etc. It is understood that different stakeholders would value BIM differently. They may share the same information but have different responsibilities and uses on the model. From a Contractors perspective, BIM brings essential value for enabling virtual construction of the structure within a single source file (Hardin, 2009). As quoted from the BIM 2009 Smart Report, â€Å"A model is Worth a Thousand Drawings†. Contractors are making use of the intelligent model for assisting them with various activities i.e. planning construction sequences, cost estimations and bidding, conflict resolution and visualization project demonstration for client and etc (Neeley, 2010). The incorporation of intelligent data improves the models construction and post-construction realities, which also enables the contractor to get closer to the world of the desig ner (Sage software 2008). The initial literature review has showed that costs are significantly reduced, time is saved and the quality improved. 2.5.1 Single source Model In conventional process, the Project Manager reviews the updated drawings and reflects any changes onto the schedule as the design progress. Many times the same information is entered into different program. Every repetition increases the probability of inconsistency and error occurrence. BIM on the other hand allow direct changes applied to the single model. As both designers and contractors have access to the model simultaneously, this corresponding process also enables them to reduce lead times which normally take place throughout the period of sending back-and-forth the documents. The collaborative environment contributes to a substantial time saving during pre construction. Extra coordination checks are also unnecessary because the information generated from the model will lead to fewer errors on site which normally is caused by inaccurate and uncoordinated information. In the case of any last minute design changes, addendums, clarifications and etc it could be altered and updat ed to the model automatically across the project team, from early design through completion (Hardin, 2009). These ensure that all parties are working with the latest information. With all the information contained within the BIM database it will definitely increase the efficiency between the Architect, Engineer as well as the Contractors. 2.5.2 The 3D Visualization Clash Detection The 3D visualisation capability of BIM models can be of great benefit as a means of testifying the workability and demonstrating aspects of the construction itself such as construction sequencing, logistics, access, storage and security (C3 System 2009). BIM allows for â€Å"building twice† which offers various benefits like improvement in Constructability, maintainability, cost estimate accuracy and etc. This reduces ambiguities before commencement of actual construction (Robert, 2005). The construction issues for layperson or non layperson are also made easier to understand as the 3D visualisation helps them to understand any constraints that the client had not made clear earlier, or were misunderstood (Furneaux and Kivits 2008). One of the major benefits which BIM could provide for contractors is clash detection. As identified by FWIC (2009), a hard clash is where more than one object is being designed to occupy the same space whilst a soft clash is where the objects in the design is too close to each other that there is no space for access or construction, or are too close that they have violated the building codes. The BIM system automatically detects and manages interferences which prevent possible delay or additional cost. The system could be set to run the check either the entire model or between certain parts of the model. 2.5.3 Construction Phasing (4D Simulation) Furthermore, one of the obvious BIM applications for improved time efficiency is construction planning. Hardin (2008) argued that the construction planning is one of the most important tasks and also one of the driving factors that determine the success of any projects. It is noted by Eastman et al (2008b) that Construction Planning and scheduling involves sequencing activities in space and time, procurement consideration, resources, spatial restrictions and etc. BIM is said to contribute in project planning solutions via the use of 4D simulation. Napier (2009) claimed that the conventional scheduling methods are labour intensive and is not easily understood by laypersons. BIM enables better communication and understanding how the schedule would impact site logistics as a result of the 4D construction phasing/planning tools that incorporate direct links to the design model, capturing spatial information which the traditional Gantt chart is unable to demonstrate. The 4D model incorpor ates time as added 4th dimension which enables the planner to visually plan and sequencing of construction activities with space and time consideration. Also, there might be specific materials and products selected from a potential range of refinements and substitutions that meet the project specification but may result in changes to some aspects of the design. As Neeley (2010) have stated, with the allowance of â€Å"what ifs†, a significant of cost, project risks and unnecessary waste could be saved by shifting the â€Å"try-and-error† process from construction site to the virtual environment on beforehand. Resource Allocation/Reducing Waste According to Egan (1998) in â€Å"Rethinking Construction†, within the construction industry almost 10% of materials are wasted and 30% of construction is rework. As mentioned by Articlesbased (2009) construction projects are very often planned based on resources availability as well as other external factors. With the 4D construction phasing/planning, the team members are able to understand the scope of work and the availability of various resources in order to optimize the resources and labour accordingly. In addition, Eastman (2008b) highlights that BIM is also accurate in providing the design model and material resources required for each segment of the work, it effectively assists in utilization of critical resources like labour, material and time during the building construction life cycle. With the improved monitoring of site logistics and the progress of project, the site management via BIM fosters just-in-time (JIT) of materials, plant/equipment and labours. Pre-fabrication Accuracy of design details are critical for determining the success of pre-fabrication, and a data-rich BIM model can have a positive impact and provide greater confidence on pre-fabrication. As BIM brings clarity towards a complex project, more contractors appreciate that BIM offers the advantage of effective coordination as the complexity level of project increases. The â€Å"Design to Build and Build to Design† concept improves accuracy for estimation and design specification for prefabricated elements thus reducing unnecessary wastage (BIMJOURNAL 2009). With greater confidence in the coordination process, many contractors are approaching more prefabrication options to help ease schedules. (BIM Smart Report, 2009) 2.5.4 Cost Estimates/schedule management From the costing aspect, Jernigan (2008) stated one of the main benefits provided by BIM is the accuracy in cost estimate during earlier stages. Conventionally, estimators have been relying on Excel spreadsheet to carry out their construction cost estimating (Autodesk, 2007), Eastman (2009b) then revealed that BIM include features for extraction and quantification of BIM component properties. By using a building information model instead of drawings; the takeoffs, counts, and measurements can be generated directly from the underlying model and the information can be linked to generate bills of materials, size and area estimations along with other related estimating information. Therefore the information is always consistent with the design and reduces the potential for human error or misunderstanding (Autodesk, 2007). This contributes to substantial time and cost saving as well as ensuring good quality of the BOQ. BIM offers the opportunity to develop more accurate cost estimates bas ed on actual elements (Hartman and Fischer 2008). Moreover, the linked cost information evolves in step with the design changes (Ashcraft, 2008). In addition, an indirect advantage that BIM could offered is the estimator would be given more extra time to bring in more value engineering, more time for risk evaluation and to more time to find any additional cost savings as the â€Å"technology† has taken up most of the grunt work from the estimator (Hague, No date).Using cost attributing features of the model to assess alternative design and construction schemes to enhance and improve the value engineering process; BIM certainly contributes in supporting the Contractor to present value for money to the Client. Neeley (2010) has claimed that the use of BIM and IPD (Integrated Project Delivery) is reducing project costs around 10%- 20% below construction costs compared to non BIM/IPD projects. 2.6 Case Studies No 1: One Island East, Hong Kong One of the popular examples of the actual Building Information Modeling Project that has been mentioned by various Authors in their research is One Island East Office Tower in Hong Kong which was developed by Swire Properties Limited. Together with the project BIM consultant, Gehry Technologies (GT) they began the process of working together to create a single, 3D electronic Building Information Model (Riese, 2006). The Project Details are summarized as follow: 2.6.1 Background Information The One Island East is a 308 meter high skyscraper with 59 stories of office space and two basement levels. The building has 70 floors in total which comprise of a sky lobby on 37th and 38th floors (Elkem Microsilika, 2009). It was Swires intention to achieve a high-quality design while improving construction time as well as cost savings by the use of collaborative, collocated work methods and integrated 3-D modeling tools. The initial objective was to save 10 percent on the cost with reduced time for construction (Shelden et al, 2008). The software tool chosen to create the BIM for this project is â€Å"Digital Project† with some of the benefits stated as follows: (Riese, 2006) Has automated clash detection and management Has a complete ME system routing tool. With built-in scripting function, enabling project requirements to be integrated for customization. Automated simultaneous file versioning and file sharing. Able to handle and manipulate large amounts of data Integrated with Primavera scheduling software with high interoperability 2.6.2 BIM Implementation (Pre-tender stage) BIM commenced after the schematic design phase. The office building has been pre-designed virtually using Digital Project by assembling up to 300.000 building components in a single master file. Almost all coordination issues were resolved using BIM. The design team, BIM consultant and Project Manager worked in one room for the first year. They also communicate with each other via a portal site for the BIM process. The DP software was capable of identifying geometric clashes and generates a list automatically. There were already several clashes and errors identified and resolved before tendering and construction. The DP tool also measured most of the quantities automatically which reduced the time and effort compared to manual take off. Also, the quantities were linked to the BIM which automatically updates when changes were made. 2.6.3 BIM Implementation (Tendering Stage) The model was provided to all tenderers which enabled them to have confirmation on the bill of quantities using the model without having to measure the quantities manually. As a result, tender process improved significantly with lower cost estimates and more accurate quantity takeoffs. 2.6.4 BIM Implementation (Post Tender Stage) Gammon Construction Limited, which was the contractor awarded for the project had full responsibility for the BIM model and began the development of highly accurate and detailed 3D BIM model for construction, ensuring that all 2D information would be firstly scrutinize in the 3D prototype before it went to the site. 2.6.5 BIM Implementation (Construction) During the construction period, the BIM model became the main visualization tool for the coordination of various project elements. There were full time modelers that assisted with the clashes identification and coordination issues where the design solutions were then incorporated into the model. A few subcontractors also participated in modeling their parts of work. 4D simulation was one of the main factors for the success of the OIE project. It was used extensively for improving construction sequence and managing risk. 2.6.6 Outcome There were more than 2000 clashes and errors were identified prior to bidding and construction stage, which resulted significant cost savings. The figure below is an example of a clash that has been detected between an electrical cable tra y and an air supply duct. Without BIM it wouldnt have been detected until the actual construction taken place which might potentially cause additional cost and time to the project. According to Shen et al.(2009), the geometric coordination off the design prior to construction is thought to achieve 10% cost savings whilst construction process modeling is thought to contribute further 20% cost savings on the construction. Gammon Construction has also reported that Construction Process Modeling saved the project at least 20 days. This project was awarded the American Institute of Architects 2008 BIM award for design/delivery process innovation. 2.7 Implementing BIM and the Potential Challenges From section 2.2 above it is demonstrated that BIM has brought numerous advantages and benefits to the industry. However there are also challenges and barriers that to be overcome before the full capability of BIM could be demonstrated and subsequently fully â€Å"enjoyed† by the industry stakeholders (Furneaux and Kivits 2008). In the very traditional and fragmented building industry, new technologies are not easily introduced. It should be noted that when a new technology is introduced, there will be a certain period of time in which the claims about the potential of the technology needs to be examined, tested and verified particularly the AEC industry which is known for the very long adoption periods of promising technologies (May et al. 2005; Salazar et al. 2006). Even though the technology of BIM is readily available and rapidly maturing but the adoption of BIM is much slower than anticipated (Fischer Kunz, 2006). Gillis (2008) made the criticism indicating that UK appears to be a more conservative and over protective country that demands proven effectiveness before considering adoption of new technology whilst Counties such as Norway, Sweden, and US attempts to proceed with new technology without 100% confirmation (Simon Gillis, 2008). As criticised by Prather (2007), most of the time, our professional would take the â€Å"wait-and-see† approach towards BIM. This is echoed by Safe software (2008) stating that our industry would mostly accept BIM only when the risk level has dropped and a clear return on investment is made known to the industry. Moreover, in these recessionary times, the money to spend on technology has got to have a good business case. The current UK industry inhibitors include contracts that has not promote working in collaboration, no external incentive for innovation, no motivation for parties to seek ways to deliver a better or quicker product and etc (Steve Dunwell, 2008). 2.7.1 Installation and operation Cost Eastman (2009) has highlighted one of the barriers to adopting BIM is the cost associated with the implementation. It is said that implementing new technology like BIM requires additional cost in respect of purchasing new software and hardware packages, training as well as changing the work processes and workflows. Also, if there are no technical expertises available within the organization, there will be a need to engage with external consultants to train employees prior to applying BIM within the organization which accounts for additional cost as well (Furneaux and Kivits 2008). Corresponding to what Eastman (2009) as well as Furneaux Kivits (2008) have said, a research done by Suermann et al. (2009) revealed that the whole installation of BIM for an organization is a costly plan when done at on one occasion, and even greater when done for several installations simultaneously for different projects. In addition, Suermann et al (2009) findings showed that there has been company which have had to increase their effort and cost allowance to do BIM due to the high learning curve. Apart from that, there is also an implication for procurement policy where consideration needs to be given to the additional funding for the development of BIM models in the first instance. The large size of BIM files will involve a different system for data sharing i.e. real time access to the BIM database between firms which are geographically distant and high speed internet connectivity will be essential (Kiviniemi et al., 2008 p.64). This would constitute extra cost for the operation of BIM. Furthermore, in order to reduce the risk of data corruption, sabotage, and loss; it is important to pay any indispensable cost associated to ensure data stability and security. 2.7.2 Embracing BIM throughout the entire supply chain Another apparent factor that has caused BIM taking the back seat is lack of commitment from the higher level of the supply chain. According to Oberle (2009), the transition to BIM requires support and commitment throughout the supply chain from top to down of an organization. In addition, The Crawley Schools PFI project in West Sussex has revealed the benefits which they have gained with the implementation of BIM but simultaneously also addressed one of their main barriers in implementing BIM was the reluctance of the supply chain in embracing this new technology, stating that some conservative individuals did not believe the benefits that BIM could offer thus were hesitant to undertake this new approach (Constructing Excellence, 2010). It is also noted that some Contractors that have too much existing workload might give the excuse that they dont have enough time to try out new technology. As quoted from Dunwell (2009), â€Å"Old habits die hard†. Most workers are reluctant to step out from their comfort zone and believed that their current handling approaches towards

Detailed CT

COST TABLES (CT): this is a cost management tool used to compare between different suppliers and their costs and an organization's production cost with that of an external organisation. (Yoshikaw, Innes and Mitchell, 1990) gave an analysis of the uses and diversity of CT. CT could be summarized or detailed. The detailed CT are done by advance Technology,' analysing' and comparing the' what if's'. The outcome of the analysis concludes a ‘make' or ‘buy' decision. This takes place within the VSC –(the powerhouse for decision making in the chain to enable it access cost of suppliers). COST SPLIT-UP – (CSU): This can also be referred to as cost analysis. Organizations making use of CSU build trust within themselves (the configurator and the partners). This model enables the supplier to make cost calculations based on the buyer's specification. The buyer gets insight into the breakdown of the cost at each stage of activity. In reference to (Bromwich, 1989), cost analysis is an essential component of SMA and IOMA. CSU is used more by organizations already implementing Porter's 1985 low cost strategy. STRATEGIC COSTING – (SC) AND VALUE CHAIN COSTING – (VCC): According to Shank and Govindarajan, (Guilding, Gravens and Tayles, 2000) is used to ascertain how strategically attractive an organization stands in the future. Strategic and market information are the main source of data to be analyzed. The use of Value Chain Costing is for the back- up activities – (design R&D, HRM) and core activities – (logistics, production, market and services) are attached a cost. STRATEGIC PRICING – (SP): Referencing (Guilding, Cravens and Tayles, 2000), the initiators of SP, determiners like opinions on competitors' prices and price elasticity, market growth economy of scale and experience are all appraised. This model is connected to markets and revenue. TARGET COST – (TC): according to (Ellram, 2002) in (Miguel, Martinez and Ramos, 2004), TC should include the production and procurement expenses incurred in a product or service. This cost can be broken down into cost of production, operating cost (marketing, sales R;D) and purchases cost. TC has three main points of focus: estimation of selling/service price based on the product attribute, calculation of TC based on targeted profit and establishing a previous TC. VALUE ANALYSIS – (VA): this has to do with the customer and customer value. This process describes the transformation of cost to revenue, reflecting what the customer is willing to pay for a value. According to (Ellram, 1996), organizations need not acquire cost for values a customer does not crave for. (CIMA, 1996, p.34) – An evaluation of determinants influencing the cost of a product with a mindset of creating valve at a minimum cost with focus on reliability and quality as features.

Endgame

Endgame The Hegelian definition of tragedy is defined as good intentions will collide in a finite area where those good intentions will develop a tragedy. Beckett’s Endgame can be included within the definition of the Hegelian tragedy. Both main characters in the play had good intentions, but were formed through obligations. These good intentions through obligation made the novel suitable to be a Hegelian tragedy. The characters good intentions were shown throughout the play. Both Hamm and Clove depended on each other to survive. They were both afraid to leave each other and be left alone.Clove admits that Hamm became a father figure to him and he once loved him but not anymore, but he has nowhere else to go. Also Hamm points out that Clove stays with him out of compassion. Nagg depends mostly on his wife, Nell. He would only wake up from his garbage bins to tell the same story to his wife and attempt to give her a kiss. However Nell dependency is the past. Nell in the play re presents life where in this type of story it is unlikely to see. The script and the film made Hamm’s parents look more childlike and pet like.The play had several themes, which consist of emptiness, loneliness, and the overall nature of beginnings and endings in other words- life and death. The repeated lines such as â€Å"finished† and â€Å"zero† represents Hamm, the protagonist, wanting to welcome in death but he is too scare to finish the â€Å"endgame†. The script made me think the characters were trapped in this small dark hole full of nothingness, which emphasizes the emptiness of the play. However, in the film there was light coming from the two windows. Outside the windows, there is â€Å"zero† nature, which also helps to illustrate the emptiness of play.Another example of emptiness being represented in the play, is that there was absolutely no sound coming from the outside or inside in the film, except for the character’s voices. T he killing of the rat and flea demonstrates the beginnings and endings of the play. Hamm told Clove to kill the flea because he is afraid of the rebirth of humanity. The stage directions in the script represent Hamm and Clove’s fear of escaping. In the film, when Hamm directs Clove to move him back to the center of the room after being pushed around the room, is one example of Hamm’s fear of escaping the room.Another example is Clove’s failed attempts to leave the room to go to the kitchen. In the film, it showed Clove’s many hesitations before leaving the room. Even though the characters had good intentions to help each other survive the â€Å"endgame†, the tragic flaws were overpowering. Nagg mentions in the play that since birth Hamm has always being afraid of loneliness. Clove finally had courage to escape but eventually returns because he didn’t have enough courage to end one thing and start a new beginning somewhere else. Hegelian trag edy suited the Endgame because the characters good intentions collided in this finite dark hole.

Even in His Rise to Power, Wang Lung Respected and Loved...

In traditional Chinese culture, there has always been a strong connection with the earth. The earth gives life and helps to sustain it, and in the end the earth is where you return. For Wang Lung, this was a concept easily grasped. He loved the land, and even in his rise to power, his connection to it remained. When he was most at peace, he was working the land. The times he grew restless were those when he was unable to farm. Often with the gain of monetary wealth, the decline of morality follows closely behind. This is magnified in the lives of Wang Lung’s three sons. The eldest son becomes obsessed with women and is eager to satisfy the desires of the flesh. For the rich, this is a common thing. Once you tire of the beautiful maid†¦show more content†¦Has it ever been more true that money is the root of all evil (1 Timothy 6:10)? And it is odd that in a culture with such a strong sense of duty and honor for their ancestors that as their father was dying they were p lanning on how to divide up and sell the land; the land that had given them so much, and the same that had put them through school and fed and clothed them and was the only thing to remain when they had nothing else? This was something Wang Lung could not communicate with his sons. They seemed to think that their wealth would go far beyond the ground from which it came. Maybe they could not remember the months they spent in the hut, or when they had no choice but to eat gruel made from the soil. They did not know how fleeting wealth was as their father had learned earlier in life. Wang Lung himself was not exempt from these same sins as seen in his sons, however. Throughout his life he had two constant forces working within him, not unlike the traditional concept of yin and yang. Yin and yang is believed to be in everything and is the essence of all naturally occurring things. They are opposite but cannot exist without each other, so the struggle is to find the perfect balance. Like with Wang Lung, when he only has the land and his earthen house but no wealth or the misfortune of a drought, he suffers. He cannot feed his family and cannot live.

My Prayer Time With God - 1224 Words

My whole life I was raised in a Catholic family only believing in Mary, Jesus mother. Until, my parents sent me to a Christian school which wasn’t something I agree with. I would always ask myself why did my parents send me to a Christian school instead of a Catholic school. But over the years I was interested in knowing more about the bible and God. I finally decided to be saved back in 2009 when I finally understood the meaning of living for eternity in heaven. Although, I’ve always had problems with praying because I was afraid of not saying the right words or starting with â€Å"Father, thank you for this day.† Every time, I was chosen to pray over everyone on the inside I didn’t want to forget anything I should pray about. Throughout the years, I learned that our words are powerful not only to others but to God. I decided to work on my prayer time with God since I tend to forget to pray for all the blessings he provides for me every day. Each day Iâ⠂¬â„¢ve spend at least fifteen minutes praying to God over all the people I care about trying to not forget or leave out anyone. It has helped me realize the power of prayer which I was afraid about in the past about making a mistake. Now, I can say with confidence that prayer is always the answer when we feel sad, anger or hurt. I didn’t understand why it took me a long time to truly comprehend the meaning of prayer and how it helps us communicate with God.

Williams-capers Columbia Southern university English Composition II Professor Dana Taylor December 11, 2011 Abstract Rap/Hip-Hop first became popular among African American and Latino among youth in the streets of New York during the cays. It was their way of expressing themselves in a friendly manner in the form of speech, fashion, and personal style. Rap/Hip-Hop music was a way for them to get their message out, by telling stories of their lifestyles.However, over the years Rap/Help-Hop music has become much more popular for its explicit lyrics, reference of drugs, alcohol and sexual explicit videos. Many may ask Could Rap/Hip-Hop music have a negative influence on todays youth, because of Its unhealthy messages? This research paper will examine the effects of rap/hip-hop music on todays youth and whether or not it has a negative influence. Over the years many researchers have conducted studies on the effects of rap/help- hop on todays youth. The results have been mixed; however there are indications that some forms of Rap/Hip-Hop music could have negative influence on todays youth.This Is due to the fact that youth start to adapt the negative aspects of the gangster rap, by displaying aggressive behaviors and committing crimes of violence. Rap gets a bad rap because some songs contain explicit lyrics, drugs, alcohol and sex. A study conducted by Ralph J. Decremented (2003) indicated that teen girls who spend more than 14 hours per week watching the sex and violence depicted in the reel life of gangster rap music videos are more likely to practice these behaviors in real life. Also, this study suggested that those teens were also three times more likely to hit a cheer, over 2. 5 times more likely to get arrested, twice as likely to have multiple sexual partners, and 1. 5 times more likely to get a sexually transmitted disease, use drugs, or drink alcohol. This Is an Indication that todays youth that listen to these songs over and over again for long period of times could have behavior and aggressive issues. Tanner (2009) Indicated that there Is a sense of Injustice that rap Is often said to involve young people with the police and courts.The study also indicates that youth who listen to rap music have a stronger connection to property crimes than the increased by poverty rather than listening to rap/hip-hop music. In a radio broadcast, De. Gordon (2006) mentioned two studies which addressed the effect that rap music has on todays youth. The first study conducted by The Prevention Research Center of the Pacific instituted for Research and Evaluation in Berkeley, Cilia. , indicated that rap songs were linked to alcohol addictions, drug use, and violence among youth.Also, a study conducted by The Center on Alcohol Marketing and Youth, Georgetown University, also suggested that youths are exposure to alcohol thought targeted marketing advertising for beer and ale by 66 recent for youth between the age of 12-20 and 81 percent market exposure to distilled spirits. Nearly two-thirds of rap songs mentioned illicit drugs and nearly half of rap songs mentioned alcohol compared to other types of music. The overexposure to alcohol was connected to cognacs and brandies, both which are linked lyrics in hip-hop and rap music, which rappers glorify and advertise in their songs.Rap music is also used to advertise clothing, sneakers, a nd cars. Rappers are walking billboards and todays youth want that same swagger. Cited in The Brown University Child and Adolescent Behavior Letter (2003), a study as conducted by a group of researchers from Iowa State University and The Texas Department of Human Services who examined over 500 students who had listened to seven violent songs and eight non-violent songs. This study measured students aggressive thoughts and their feelings.The results were that violent songs led to more aggressive interpretation of words that also increased the speed in which the students read aggressive vs.. Non-aggressive works and increased the proportion of word fragments that filled in to make aggressive words. Their study also indicated hat the violent songs increased violent thoughts causing youth to act out. The popularity of Rap/Hip-Hop music and Hip/Hop styles has now reached the Middle East. Iraqis youth in are now starting to imitate hip-hop lifestyles of American soldiers.Youth have now started to adapt hip-hop styles such as, dancing, wearing baggy pants, slangy English, and cutting $ signs into their close cropped hair. Tattoos are now also becoming popular among Iraqis youth. This goes against Salamis strictures on baring their skin. Not all Iraqis welcome the culture of the American Hip/Hop style, because they feel that Iraqis youth are now beginning to reject authority and other forbidden behaviors, like engaging in forbidden love affairs.Iraqis youth feel that their eyes are now open to the outside world since living under Sadism Husseins dictatorship. Iraqis youth are now also starting to use the internet and are watching satellite TV, which allows them better understanding of American cultures, both positive and negative aspects. In a book written by Michael Tyson, Reflecting Black: African-American Cultural Criticism. He addressed the question Is Rap music really as dangerous as many artists argue: Michael Tyson (1993) states that Rap music is a form of profound musical, cultural, and social creativity.He also stated that Rap music expresses the desire of young black people to reclaim their history. He defenses the negative impact on Rap/ Hip-hop music, which the general public claims that Rap/Hip-Hop expresses and causes violence among youth. It is in his opinion that many rappers have spoken against the violence in Rap/Hip-Hop. Rappers KIRKS-One spoke against Rapper KIRKS-One wanted youths to realize that not all Rap/Hip-Hop music called for violence behavior among youth. Also, rappers such as Will Smith and his partner DC Jazzy Jeff rapped positive messages to youth about having fun in the summer time, not glorifying drugs, alcohol or sex. Some feel that rap can be negative and positive on todays youth. Michael Tyson (1993) feels that Rap/Hip-Hop music is getting a bad rap. Could that be true, or is Rap/Hip-Hop really unhealthy for todays youth? Over the years research, books and studied have been conducted to determine if violent and explicit lyrics in Rap/Hip-Hop music really causes or promotes violence in todays youth.Since its beginning in the sasss Rap/Hip-Hop has gone from being UN to listen to now being a explicit rated albums. In todays time Rap/Hip-Hop glorifies drugs, violence, and sex at an alarming rate. Todays youth are also embracing the lifestyles of rappers in their language and attitudes, with their want of money, cars, drugs and alcohol that rappers talk about in their lyrics causing them to become materialistic teenagers. What must we do as concerned parents?We must be aware of what our children are watching and listening to. Parents must be involved in what their children are purchasing and they must ask questions to understand what their children are experiencing. In the sasss C. Dolores started a crusade to stop the sale of offensive rap music to minors. Mrs.. Tucker outspokenness earned her enemies, however she remained relentless with her crusade against what is called gangster rap. Her concerns were that the lyrics were misogynistic and threatened the moral foundation of the African American community. Conclusion Rap/Hip-Hop music became popular in the asss, since than it has changed the world; youth in every corner of the globe have adopted the culture, the speech and the style. Because Rap/Hip-Hop music has become so popular, many people think that his type of music is making todays youth more violent, due to the glorification of violent, explicit language, sex, disrespect for authority, and disrespect towards women.
