Building Information Modeling ( Bim )

During concept design and developed design stages, BIM technology and processes were used to develop and establish building performance and the basis of design in accordance with the client’s standards. The models were required to be interoperable with analytic tools for, including but not limited to, building envelope, orientation, daylighting, energy consumption, Building Management System (BMS), renewable energy strategies, life cycle cost analysis, and spatial requirements (Andrian X Sanchez 2015). Thus the main stakeholders of the PCH project established a series of BIM-related objectives:

In his paper, the author explains us how the technology advancement is taking place, how 2D modelling started initially, how it led to 3D modelling and now how building information modelling techniques are being linked to 3D modelling. BIM is not just about modelling, but it also includes project planning, design and construction. He clearly explains what BIM is in the form of a flow chart. Where he says that B in BIM stands for Residential, commercial, healthcare, institutional, sports and entertainment, I in BIM stands for Spatial, element, systems, quantities, schedule, operations and M in BIM stands for site, architectural, structural, MEP systems, sustainability and management. This all phases of the program are a continuous chain where programming, design, pre construction, construction, operations, and demolition are done. This research also supports that the concept of building information modelling is not only useful for the building’s geometric modelling, but also it can assist in the management of construction projects. In this research, the author has collected information from 35 construction projects that have already utilized BIM. The most common result that was observed was the cost reduction. For some people, BIM is a software application, where as for others, it is a process for designing and documenting

Chapter 2 provides a methodical review of relevant literature in the field of BIM, the perceived barriers with its adoption and implementation by SMEs and an analysis of the data found.

B.I.M stands for Building Information Modeling, intelligent model-based process that provides insight to help you plan, design, construct, and mange buildings and infrastructure. B.I.M changes how buildings, infrastructure, and utilities are planned, designed, built, and managed. Autodesk B.I.M solutions help turn information into insight and deliver business value at every step in the process. B.I.M incorporates major elements of estimating, cost and project management. As a result, the B.I.M computer model is a living representation of the actual structure at any given time. B.I.M is more than drawings- it is a date repository for building design, construction, and maintenance information combined in one convenient model to share. The benefits of B.I.M are that there are reduced changes during construction. Reduced conflicts during construction and improved construction. Improved collective understanding of design intent reduces claims, disputes, and conflicts. B.I.M provides the capability to design efficient “Green Buildings.” The future of B.I.M will only make B.I.M better, the Information of B.I.M will be utilized more, designers, constructors and building owners will leverage the information that is right in from of them to add value to the building they are producing. Room and furniture, fixture, and equipment validation between

Once all the tasks from the schedule are linked to their corresponding 3D elements, the 4D simulation can be viewed. The simulation shows the progress of tasks taking place on a Day-to-Day basis. Planning of the labor and resources can be done for any particular element of the building by simply scrolling down to a particular date in the course of construction in the

The changes that have come about with the introduction of BIM usage within UK Government contracts necessitate for Education Institutes to re-evaluate existing construction specific courses to adequately implement BIM into the curriculums at all levels to provide continuing educational development within construction specific courses (Suwal, 2013).

Building Information Modeling “BIM”, is an intelligent, model based process for planning, designing, building and managing buildings and infrastructures. BIM is a very powerful way for designers and architects to lay out building plans and designs. BIM is not just single piece of software or model, but a system of information processing and collaboration, with data fixed within the model. BIM begins with a 3D digital model of the building or infrastructure that is being planned out. However, the model that BIM provides is much more than just a 3D model. BIM technology allows for the project managers, designers and architects to see virtual equivalents of all the buildings parts that are going to be used throughout the entire construction process of the building. BIM brings together all of the information about every element of a building, and stores all the data in one place. It allows anyone working on the project to access the data in order to integrate different aspects of the design more effectively. BIM reduces the risk of mistakes which in turn helps to stay on budget and enhance efficiency.

Besides, audit of Building Information Modeling devices, basically Revit Architecture and Synchro further showed the capable utilization of 3D, 4D and model based booking. This showed that the development business is unquestionably making headway with BIM idea and BIM devices. The BIM is beginning to turn into a typical practice in the development business. The present interoperability difficulties will inevitably be relieved and BIM instruments will turn out to be more financially savvy and efficient.

Although BIM proved its capability in design and construction phases, implementing BIM in FM can face some technology and organizational challenges such as “Diversity in BIM and FM software tools, and interoperability issues;” (Kiviniemi & Codinhoto, 2014, p. 666) and the resistant from some organizations to adapt new technologies. (Kiviniemi & Codinhoto, 2014, p. 666)current work processes and organizational structures should be adjusted to use BIM in FM, by training on the new software tools and process, also the organizations should assign responsible people for loading data into the database.

The future of our industry lies in how best we can integrate and communicate all our work with various stakeholders to manage a project efficiently. This has given rise to an area called construction informatics where a significant amount of research is being done. The area deals with a range of subjects from integration to interoperability and from knowledge mining to strategic management. This area came into existence from two fields. The first was the use of computers to design and carry out time and cost calculations. The other was for computers to categorize and store essential information. Currently, integration, interoperability, innovation along with strategic management of Information and Communication Technologies are the key areas of research of construction informatics (Isikdag 2009).

According to the collected data and the relations associated with involved components, the researcher summarizes the beneficence and contribution of IPD, Lean principles, and BIM in the conceptual model. In order to establish a powerful checklist for construction projects that expect to apply all remarkable characteristics of each element in ILB’s collaboration, six prime measures are evaluated and considered for the common synergies. As a result, the summary is represented in Table 5.2.

This construction strategy is set to start applying Level 2 collaborative 3D BIM with Library Management (created in separate discipline models) on all public building projects by 2016, with the aim of decreasing the total cost and carbon emissions from construction processes and activities by 20%.

As BIM is becoming more and more recognized within the construction industry, more construction organisations are aware of the advantages it can bring to their business. Many organisations are not aware of the benefits that BIM can bring to a job role with in the business.

Traditional building design has been largely reliant upon two-dimensional technical drawings (plans, elevations, sections, etc). Building Information Modelling extends this beyond 3D, it is a parametric 3D model enhancing the three primary spatial dimensions (width, height and depth) with time as the fourth dimension and cost as the fifth. BIM therefore covers more than just geometry, it also covers spatial relationships, light analysis, geographic information, and quantities and properties of building components (for example, manufacturers ' details).

BIM is a new technology that should be implementing on the construction industry. U.S. General Service Administration or known as GSA is more categorical in their definition of BIM which is:
