BIM

BIM
With the rising cost of energy and growing environmental concerns, the demand for sustainable building facilities with minimal environmental impact is increasing. Buildings consume close to 40% of all energy used in the United States and account for 40% of global CO2 emissions . The rising cost of energy and growing environmental concerns have pushed the demand for sustainable building facilities with minimal environmental impact through the use of environmental sensitive design and construction practices.
BIM Analysis
As with traditional physical models and drawings, evaluating building performance based on the graphic representations of conventional CAD or object-CAD solutions requires a great deal of human intervention. A Building Information Model represents the building as an integrated database of coordinated information. Beyond graphically depicting the design, much of the data needed for supporting sustainable design is captured naturally as design of the project proceeds. This approach gives architects easy access to tools that provide immediate feedback on design alternatives early on in the design process.
* Building orientation (to select the best building orientation that results in minimum energy costs)
* Building massing (to analyze building form and optimize the building envelope)
* Daylighting analysis
* Water harvesting (to reduce water needs in a building)
* Energy modeling (to reduce energy needs and analyze renewable energy options such as solar energy)
* Sustainable materials (to reduce material needs and to use recycled materials)
BIM Documentation
BIM models are sufficiently detailed to generate construction drawings and documentation. It includes an accurate set of drawings incorporating appropriate data regarding each step of the construction process and all details required to make a comprehensive estimate and ultimately construct the project. BIM Documentation defines CAD to BIM Conversion, Schematic Documentation, Design Development Stage, Schedules & BOQs, Pre-Bid Documentation, Construction Documentation, Shop Drawings, As-Built Documentation.

BIM Fabrication
BIM for Prefabrication and Fabrication. Preparing a building component or assembly for fabrication is a time consuming process that depends on numerous complex factors. BIM facilitates a variety of related design/construction activities, including digital fabrication and Shop drawings of building components.

BIM dimensions – 3D, 4D
Linking extra ‘dimensions’ of data to your information models has the potential to give you a richer understanding of your construction project – how it will be delivered, what it will cost and how it should be maintained. Here we explore 3D, 4D and show how adding extra information can make for more timely decisions and, ultimately, better buildings. 4D BIM adds an extra dimension of information to a project information model in the form of scheduling data. This data is added to components which will build in detail as the project progresses. This information can be used to obtain accurate programme information and visualisations showing how your project will develop sequentially. Drawing on the components of the information model being able to extract accurate cost information is what’s at the heart of 5D BIM. Considerations might include capital costs (the costs of purchasing and installing a component), its associated running costs and the cost of renewal/replacement down the line.
BIM Construction Logistics
A Model Use where 3D models are used to plan crew/equipment movement on the construction site, compare construction systems, and plan when/where to place/remove temporary structures. Construction Logistics also refer to analysing construction materials’ flow, placement, and storage…Also refer to Lift Planning
BIM Operation and maintenance
Most managers in existing buildings need to manage the influences of daily activities as they oversee the maintenance and operations of these facilities. Typically, their top concern is managing thermal comfort. Managers also must manage the quality of the indoor environment — humidity, lighting, sound, etc. — as well as the quality of services provided, building operating costs, energy use, water use, recycling, and waste reduction. With the rise of reporting mandates, measuring building performance is more important than ever.
BIM Demolition
Due to the rising worldwide awareness of green environment, both government and contractors have to consider effective construction and demolition (C&D) waste management practices. The last two decades have witnessed the growing importance of demolition and renovation (D&R) works and the growing amount of D&R waste disposed to landfills every day, especially in developed cities like Hong Kong. Quan-titative waste prediction is crucial for waste management. It can enable contractors to pinpoint critical waste generation processes and to plan waste control strategies. In addition, waste estimation could also facilitate some government waste management policies, such as the waste disposal charging scheme. Currently, tools that can accurately and conveniently estimate the amount of waste from con- struction, renovation, and demolition projects are lacking.
BIM Renovation
Building Information Modeling (BIM) is a process involving the generation and management of digital representations of physical and functional characteristics of Projects. This study work is intended to understand the links between BIM and energy analysis tool for renovation project. To achieve this goal; to reduce the energy use and carbon emissions from buildings, there is a need to efficiently renovate the existing building facilities to improve energy performance. Building Information Modeling (BIM) assists architectural assess different alternatives at the renovation stage of a building life so that effective energy strategies are attained within the building constraints. However, for the retrofitting work, there is a need for a proper and systematic methodology to monitor the behaviour of buildings and to make critical decisions to ensure that the energy criteria of the design are really met in practice. This introduces a conceptual BIM-based model that can improve the energy and meet the requirements for high rise residential buildings.
BIM Programming
A process in which a spatial program is used to efficiently and accurately assess design performance in regard to spatial requirements. The developed BIM model allows the project team to analyze space and understand the complexity of space standards and regulations. BIM (Building Information Modeling) is an intelligent 3D model-based process that gives architecture, engineering, and construction (AEC) professionals the insight and tools to more efficiently plan, design, construct, and manage buildings and infrastructure.
BIM Conseptual Design
Historically, conceptual design has been poorly served by CAD software developers. Many Building Information Modelling (BIM) design tools were first sold to improve the process of creating co-ordinated detail drawings, with features like massing and simple geometry manipulation failing to appear for years. Concept design generally takes place after feasibility studies and options appraisals have been carried out and a project brief has been prepared. The concept design represents the design team’s initial response to the project brief.
BIM Detailed design
BIM (Building Information Modeling) is an intelligent 3D model-based process that gives architecture, engineering, and construction (AEC) professionals the insight and tools to more efficiently plan, design, construct, and manage buildings and infrastructure. Level of detail for BIM. Building Information Modelling is a very broad term that describes the process of creating and managing digital information about a built asset such as building, bridge, highway, tunnel and so on. The level of detail of a building information model increases as the project proceeds, often based in the first instance on existing information, then developing from a simple design intent model through to a detailed virtual construction model, then an as-constructed asset information model (AIM). Different aspects of the model may develop at different rates, may originate with different members of the project team, and their development may pass from the employer, to consultants, to the contractor and suppliers and ultimately back to the employer.
