Introduction and Background to the problem With the alarming growth in the energy costs and environmental concern in construction projects there is a continuous demand for sustainable buildings. LEED® evaluates the sustainable performance through a 69-point credit system which mainly emphasizes Indoor environmental quality, energy and atmosphere, sustainable sites, water efficiency, materials and resources and innovation in design (Azhar, Carlton, Olsen and Ahmad (2011)). The advent of Building Information Modeling (BIM) actuated the integration of different construction data in a single model. Bynum, Issa and Olbina (2012) suggested the implementation of BIM in the Design phase of construction to enhance the sustainable aspects of the design and construction. Azhar et al. (2011) described the use of BIM in determining material’s reuse, effective building orientation and perform daylight analysis to increase the sustainability of the building. According to the previous research the use of BIM during the design phase to perform the energy analysis will result in an efficient design minimizing the energy consumption of the building resulting in a sustainable building. Problem Statement The proposed study will identify and assess the impact of Building Information Modeling for LEED® rating analysis of newly constructed multi-story buildings in Texas. Objectives The objectives of the research are 1. Investigation of the BIM contribution for LEED rating analysis. 2. Analysis of the benefits and obstacles of using BIM to support the LEED rating system. 3. To provide recommendations on how to apply BIM for LEED rating analysis.

I got a wonderful opportunity to work for one of the best construction companies, which is Hathaway Dinwiddie. Hathaway Dinwiddie has been in construction industry for over 100 years. Back then they started as Dinwiddie construction and been a part of a lot of historic buildings in California. Hathaway Dinwiddie has an expertise in Building information modeling (BIM), Partnered delivery and lean construction, Design-Build, Quality Control, Best Value exploration, Sustainability and safety. Hathaway Dinwiddie has a history of using BIM back in 1998 and now they are using it at every stage of their projects. They use BIM to summarize quantity surveys, develop preliminary construction strategies and maintain coordination between their team and their partners. Hathaway Dinwiddie provides services like General Construction, Preconstruction, Design Build, Construction Management and Interior and special projects. Hathaway also believes in being one step ahead of its competitor and has been investing in the research and development field also.
The modifications of existing building and the construction of new ones under the most recently proposed building codes would be too costly to implement. The billions of dollars would be required into order to perform the suggested renovations. Marolyn Davenport, a vice president at the Real Estate Board of New York and a member of the task force, states that, “Burdensome restrictions would make construction too expensive.” He goes on to say, “While you want to incorporate safety features, at the same time we have to compete with surrounding areas” (Qtd. in Chan 1). Buildings that would fall subject to the new building codes would be given an unfair advantage in the competitiv...
The paper presents a detailed discussion on implementation of BIM in a construction project by defining a BIM team in the various phases of construction i.e. from conception to commissioning. Also, the paper presents a brief discussion on processing the information utilizing the i-rooms.
It includes a very wide range of modeling features, including geometries (but not limited to), basic building elements (slabs, columns, beams, doors), facilities management, electrical, ventilation and other subsystems, and structural analysis constructs, identity, organizational, process and cost modeling constructs. The specification is divided into platform and non-platform domains, but even the core platform constructs include over 300 classes. Implementing the entire specifications is almost impossible considering the size and scope of IFC. In addition to the size and complexity, individual IFC models tend to be very large. For a large building, including the geometry and semantic information for all building elements, the size and complexity are still considerable even when split the model (Steel & Drogemuller,
This research Study had increased the knowledge of the researcher in understanding of BIM as a phenomenon. The process of reporting the research had also added more knowledge to the understanding of the researcher on research methodology, especially on how to efficiently carry out a case study research. General learning of how to plan and manage time is part of the process of this research study. The research study had also increased the endurance and perseverance of the researcher. The improvement in the attitude of having a pragmatic and holistic view of issues is also one of the benefits gained by the researcher. Among the gains of the process is also an improvement on writing skills.
Therefore, it was republished online – incorporating flexibility in stages such as planning permission and procurement allowing them to be moved to suit the project’s schedule. It also supports BIM modelling applications allowing project plans to be created and shared easily and focusses heavily on the sustainability of buildings. The work stages were also re-structured and re-named providing the user with core objectives, strategies, and suggested BIM and Procurement tasks for each stage. The first stage (stage 0) is strategic definition, here
Quantity takeoff is an essential task in the construction process as it provides the basis for other construction tasks that follows. The building elements are measured and these quantities are then used to estimate the cost and the relevant workload involved. This information is then assembled in a Bill of Quantities (BQ). The BQ structures and organizes the information about measurements, productivities and costs, according to the construction task and considers the actual order of the construction process. For example, the foundational elements are under the same section in the BQ while the roof elements are under the same section in the BQ.

In conclusion, the designers and builders of the tower have an undesirable job: creating a building that is functional, modern, sustainable and unique. At the same time it is honoring the memory of the people that died in and around the buildings that stood there before. While the green sustainable features have been criticized for being too expensive, they will do more than save just water, electricity and emissions. They and the grace of the building will inspire a generation of green and safe skyscrapers for the twenty-first century. This building has become one of the safest, environmentally friendly and expensive ever built, but as critics slate the building for various reasons, one cannot take away the determination through political, social and economic status that designers and workers have created such a beautiful building with great meaning.
People don’t want to have a complicated way of life, they want to be simplistic and still be looking after then environment. My goal is to therefore create sustainable living but on a very simplistic bases because more often, people like to do as title as possible. In 2015 it is very important to go green, even though scientists are looking for new planets to move to, it is still very important to look after the planet that we live on now. The architecture community is aware of the importance of greener living. SANS 10400 Part X and Part XA is a SABS document that are responsible for the requirements of environmental sustainability and energy usage in a building. The document then ha tables that a building needs to comply with such as, Maximum annual consumption per building classification for each climate zone . These documents are important for creating greener buildings but they are not enough, documents such as SANS are not enough, for example electricity, the world is running out of non-renewable resources. Unrenewable resources such as coal but places such as South Africa are still running and building more coal power stations or are looking into creating Nuclear Power stations instead of infesting more into wind turbines for power. Problems like this need to be fixed not just in the county but in the homes people live in and the buildings people work in,

“The building sector contributes up to 30% of global annual greenhouse gas emissions and consumes up to 40% of all energy” (UNEP). The building sector is one of the leading contributors to global warming and, as a result, is one of the leading contributors to melting ice caps, rising sea levels and the recent proliferation in extreme weather conditions. However, it does not just contribute to global warming; the building sector also contributes to urban pollution. In the US alone, the building sector generates hundreds of millions of tons of municipal solid waste each year. It is clear that the building sector must change if we are to survive as a species. Ultimately we need to convert our cities into “sustainable cities,” but a good start in that direction is a practice in the building industry known as Green Building. A Green Building is an environmentally sustainable building designed, constructed and operated to minimize its total environmental impact. Some of the main goals underpinning Green Building include reduced energy consumption, water conservation and recycling. Green builders do this by using renewable energy such as solar, wind or hydro, which provides the buildings with clean energy and zero carbon dioxide emissions. They manage water through water efficient irrigation systems, captured rain or site-recycled water for onsite landscaping. They also develop a waste management plan that diverts a substantial amount of solid waste from landfills to salvage facilities. A common assumption that many people make is that Green Building is very expensive. But the cost of a building, house or apartment complex that is Green depends on how “green” they want it to be. Prices can range from a mere one percent i...

The use of green materials is better for the environment because they have a positive impact on the planet. Looking at our environment today we see a place that has been facing a massive climate change. Scientists have been concerned over global warming for decades. The ongoing increase of the earth’s temperature is believed to be caused by the greenhouse effect (“Global Warming” 27). Building with green materials produces significantly lower greenhouse gas emission. Specifically, wood as a material for building products, requires considerably less energy than other building products such as steel and concrete. Wood product manufacture results in fewer greenhouse gas and other air-polluting emissions (“Green Building Benefits”). Green building also results in waste reduction. In the United States, construction and demolition creates a huge amount of solid waste. Green building limits the waste prod...
