CHAPTER 1
INTRODUCTION
1.1 Background
Construction industry has established and uses the basis of object-oriented building product modeling since 1990s. Initially, certain market sectors such as structural steel utilized the parametric 3D modeling in their design. Recently, various BIM tools became readily available when realizing the benefit of parametric 3D throughout the construction industry. This is a reward of construction industry’s dedication to Building Information Modeling for the last 20 years (Eastman, 2008). Construction industry has realize the true benefits of technological advancement in transforming of construction process to be more better.
1.2 What is BIM?
The conceptual underpinnings of the BIM system go back to the earliest days of computing. As early as 1962, Douglas C. Englebart gives us an uncanny vision of the future architect. Englebart suggests object based design, parametric manipulation and a relational database.
Seeing buildings through the lens of the database contributed to the breakdown of architecture into its constituent components, one of the first projects to successfully create a building database was the Building Description System (BDS) which was the first software to describe individual library elements which can be retrieved and added to a model. This program uses a graphical user interface, orthographic and perspective views and a sortable database that allows the user to retrieve information categorically by attributes including material type and supplier. The project was designed by Charles Eastman who was trained as an architect at Berkeley and went on to work in computer science at Carnegie Melon Uniersity. Eastman continues as expert in BIM technology and Professor at the G...

...ion of BIM goes hand in hand with a new method that allows more partnering-like relationships between stakeholders. These collaborative relationships can create more cohesion between stakeholders, thus making it easier to work together towards a common goal of implementing BIM. The initial expenses associated with education and acquiring the hardware and software are necessary for transformation from traditional construction projects to BIM. Based on the result of questionnaire by Yan and Damian (2011), this category poses the largest challenges about 40% USA respondent and 20% UK respondent believe that their companies have to allocate lots of time, expenses and human resource in BIM training. The BIM experts pointed out that this is not a real challenge but should rather be viewed as an investment, which would pay off in the long run of construction company.
Whereas, there have not been many studies exploring mathematical modeling that integrates the subjects of CSCM and construction project management. In this study, we proposes a coordinated supplier selection and resource-dependent project network with final project review sequencing which builds an interface between CSCM and construction project
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;
The objective of this report is to present and discuss the management of field construction projects. These projects involve a great deal of time and expense, so close control and management is paramount if they are to be completed within the established time and cost limitations. The term construction management is applied to the provision of professional management services to the owner of a construction project with the objective of achieving high quality with low costs.
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.
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.
Classification systems are available for new building and major renovations as well as existing buildings.

Another reason for such increase in knowledge on BIM system is application by construction firms like NIKA Architects + Engineers. Respondents have seen BIM system in application or at least held a glimpse through various commercials by such firms, which has engaged the viewers to explore this ideation.
This document portrays, in full context, the requirements for developing the specific BMS solution. As such, it represents an important guideline and a complete reference for the upcoming phase of software development and idea generation. By applying a process that leads to a high-quality result, the needs of the people who use the product will be met. Moreover, this document will act as the basis for validating the final complete product in compliance with the owner’s demands. When erecting such a framework, the basis of all the work must be robust yet malleable in order to perform any changes of the end product. For these changes to be put into effect, the client must have prior knowledge and be the direct final decision maker.
In conclusion, although the development of modern architecture and the intervention of computer technology to advocate this development, the contemporary architectural outcomes have became more complex and complicated with potential formulation problems. As a result, the new architecture theories came to put boundary lines between being in the range of these problems and producing elegant modern built environment. The seduction of computer-produced form also enhances architects to involve in seeking for new theories to develop the discipline and work to combine formulization with materialization. Finally, some of these theories are accepted and some other still a controversial aspect in architecture.
Digital fabrication is coming into the construction industry to create precisely crafted and complex buildings in response to the new competitive environment and construction market demands. Thanks to advanced technology, the good revolution can be seen in most industrial activities. Almost all of the industry sectors are trying to keep themselves up to date with new related innovation to boost their sustainable growth. However, unfortunately architects and construction engineers have been more conservative despite all of the massive global investment in the construction sector. This conservative trend was started many years after great prosperity and success in the other industries. As an example, in comparison with the more developed automotive industry, the construction industry has been weighing the pros and cons of doing automation, and it is still under development. Despite some limitations and lack of information over the 80’s and even 90’s, but the current status indicates good progress. Today, most of architectural design is no longer possible without computer technologies. The models have become more complex and require advanced tools to understand design codes and implement fabrication processes. It can be said, that the advanced automated tools with a user-friendly programming system can bring incredible solutions for architects and construction engineers. Many researchers have made significant studies to consider all possibilities and limitations of digital design-construction in various types of procedures.
Architecture today is more focusing on aesthetic instead of the surrounding environment. In the result, the importance of the relationship between architecture and environment have been neglected and forgotten.
In computing we are used primarily to sketches, engineering drawings, and diagrams. But in other restraints a much wider range of demonstrations are employed, often in parallel, not competing, but complementing each other. For instance, within the architectural practice relevant representational forms encompass conceptual models plans, diagrams, sketches, and models of different sizes and materials. In design, interests are put in the actual building and construction process, and it is an experience that scale models addresses issues like buildability and economy. This is because different techniques of representation and different media allow the exploration of different aspects of a design idea. 3D block models are used as an exact representation of the proposal. The scale models imitates the building process, (LETH & GORI architectural firm, 2014). Whilst essentially being produced for the client, the designers will make subtle design decisions as the block model is produced. By undertaking or closely overseeing block model production, the individual designer can maintain the interactive inputs necessary to ensure a successful outcome. Although important to an entire team, the marketer is particularly interested in the block model. They do not believe in images. In other words, they only trust the quality of the
This paper explores what it takes to be a construction manager and the responsibilities of being a construction manager and the skills that a construction manager should have. It also explores what good construction managers do to have success on their construction projects and the steps that a construction manager must follow to end a project and meet their deadlines at the same
I have completed Bsc (Hons) Construction management at the University of West London, and I would now like to further my career by studying MSC Project enterprise and management at UCL. I have made this decision after understanding that this course will enable me to develop a broad understating of construction management of large and complex projects and increase my commercial awareness of these projects. I also expect this course to be taught with both academic rigour and place consistent emphasis on practical application of what I learn to construction environment. After working in construction for industry for almost 2 years, and studying a bachelor’s degree I feel I am more than capable of completing Msc Project Entriprise with success as I have already experienced the rigors & dynamics of university education.
