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.
LEED, or Leadership in Energy & Environmental Design, is a certification program for green buildings with stringent requirements for building energy efficient and environmentally responsible structures. Some requirements of this program include specific building materials, smart grid capable, gray water reclamation systems, green space minimums, high levels of insulation and low thermal transfer glass (US Green Building Council). Green buildings are a must if we are to sustain our current level of growth. Despite the higher initial cost of these buildings, the long term energy savings make these buildings a smarter choice for
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...
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,
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.
The findings of this research had shown both the progress of BIM implementation that have taken place over the years and at the same time the limitations to BIM usage in the management of projects. In the view of the limitations, this researcher is of the opinion that certain steps can help to improve the efficiency and effectiveness of BIM implementation in construction projects. The research results had suggested that BIM is applicable and beneficial to all stakeholders in all phases of construction projects. It is also found that BIM have collaboration, legal and implementation problems of which this researcher recommends as follows;

A green building (also referred to as sustainable building or green construction) is a structure that employs an approach that is responsible for the environment besides being efficient in regard to resources all through its life cycle: This is from selecting the site to designing it, constructing, operating, maintaining, renovating and demolishing it. To achieve this, the client, the engineers, the architects and the entire design team closely cooperate at all stages of a project (Yan and Paliniotis, 2006). Practicing Green Building complements and expands the conventional building design areas of comfort, durability, utility and economy.
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
The beginnings of today's green revolution can be traced back to the environmental awareness of the 1960s and European design. New construction techniques have lead to the development of innovative materials and design concepts. Green buildings are designed, constructed and commissioned to ensure they are healthy for their occupants. Successfully designed green projects can involve an extensive array of factors, ranging from the resourceful use of materials, to careful consideration of function, climate, and location.

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.
Sustainable design seeks to reduce negative impacts on the environment, the health and comfort of building occupants, thereby improving building performance. The basic objects of sustainability are to reduce consumption of non-renewable resources, minimal waste, and create healthy, productive environments (“Sustainable Design”). Focusing primarily on the sustainable design principles, there are five, including: low-impact materials, energy efficiency, quality and durability, design for reuse and recycling, and renewability. As sustainability appears to become the necessary trend in architecture, the question concerning the cost versus outcome of “going green” really an investment or a waste of time and money comes to mind. With our research provided below, we believe the expenses may truly be with the investment in the end.
“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...
