Ask the question "what is BIM?" and you'll get as many answers as people you ask. BIM means different things to different people and none are necessarily wrong (regardless of how strongly you feel). I recently asked several people to describe BIM in 50 words or less and below are 23 responses, plus the NBIMS definition for comparison. My conclusion is in the next post...
--
BIM is the 3D drafting process used by all disciplines on the building team to show in detail the final design of each system i.e. structure, ductwork, plumbing, electrical, architectural, lighting, etc. and ultimately shared interoperably with contractors and sub-contractors for the benefit of the project’s budget and schedule.
--
There are different “levels” of BIM, one being simply using software like Revit or Tekla. Two being actually exchanging the data on the software with another user on a different platform and collaborating on a common model. Three being full Integrated Project Delivery, with early involvement of all project disciplines, down to subcontractors.
--
BIM is the process of using a digital building model for design, fabrication, and maintenance. In other words, using computers as sophisticated computing devices rather than mere storage systems
--
Building Information Modeling is a “big picture” design process which is defined by the team that uses it. The general idea is that it is an information sharing process where by all the design professionals, construction trades, and everyone in between will have a common operating picture by which they can communicate efficiently and put coordination decisions back into the hands of the designers where good decisions can be made with the least impact on final cost.
--
BIM’s proponents: BIM is collaboration; specifically, collaboration that results in cost cuts, project efficiency, and the sharing of information so designers don’t have to reinvent the wheel with every drawing.
BIM’s opponents: BIM is software that is costly, too time consuming to become familiar with, and requires a departure from what is normal and comfortable.
--
BIM is an all encompassing term referring to the coordinated creation, exchange, management and use of intelligent data representing the various aspects (facility management, design, construction, use, maintenance, deconstruction) and components of a building throughout its life between all affected parties (owners, facility managers, collaborating members of a project design and construction team, maintenance engineers and building users) from a spatial, parametric, cost, schedule and performance perspective.
--
BIM is a building delivery system that uses the latest technology to bring value to a project by interfacing with all the major building components to generate an electronic “Virtual Building”. As a result of this process the owner will benefit from reduced construction costs, shorter construction schedule, fewer change orders, less litigation, earlier occupancy, and reduced operating and maintenance costs.
--
When I think of BIM, I think of interoperability between design professionals and construction trades. A tool that should help improve constructability, although this still depends on the design teams willingness to communicate and work together, especially early on in the project.
--
Building Information Model (“BIM”) is a process where by building design and operability information is shared among the project’s stakeholders. Through multi-discipline collaboration in the development the complete BIM Model, all the stakeholders benefit. These benefits include, cross-discipline design optimization, up front conflict resolution, schedule optimizations and project cost reductions.
--
Building Information Modeling (BIM) is an umbrella term referring to 3D building modeling integration software systems. Allows design from multi-disciplines to be compiled in one master file. This can facilitate time and cost savings by consistently linking objects spatially to all views of the design process.
--
Today it’s primarily used for clash detection. Once programming is standardized it could conceivably allow details to be used for procurement and CNC part fabrication equipment
--
BIM is a software-based design optimization tool that brings all building systems together in one three-dimensional model. It creates a better building by showing what works best and what doesn’t work at all—before the building is constructed. It is a symbol of efficient, collaborative, sustainable design.
--
Building Information Modeling has two key components: building three-dimensional (at minimum) data-rich building models and using those models as a collaboration tool amongst the entire project design and construction team. This tool/process takes many shapes and forms; however, if those two components aren’t there, I don’t consider it true BIM. Adequate software integration is a key “back-office” necessity for BIM tools/processes to function properly.
--
In my mind, the term “BIM” is simply a vehicle – or tool – to assist in project collaboration. To describe it as “simple” may be an understatement, but I consider BIM only a means and methods toward achieving a bigger goal. I anticipate that “collaboration”, as a concept, will remain important in the years to come, while the mechanisms we use to get us there may vary.
--
BIM is the catalyst that allow for collaboration to exist in a seamless approach to project construction. BIM allows for optimization of project costs, schedules, material selections, layouts, workflows and sustainability. BIM is the end user’s FIM (Facility Information Model)
--
BIM is a means of collaboration using electronic technology among project team members to build a project virtually before building it in the field. The intent is to build it once, right, in the field the first time with reduced errors and change orders, thereby shortening project schedules and saving cost. In its complete form, the BIM model(s) will be used in the ongoing operation and maintenance of the completed project.
--
Building information Modeling is the collection, organization, and managed accessibility to data and information related to a building or buildings that may be used for a wide range of purposes that may include planning, construction, life‑cycle monitoring, risk assessments, and eventually decommissioning and disposal.
--
1. Building Information Model: A digital representation of the geometric and qualitative aspects a building project.
2. Building Information Modeling: The process of developing, exchanging, and using digital Building Information to improve building design, construction efficiency and building performance.
--
BIM is the business process, workflow, and information needed for efficient facility lifecycle management, support by digital technology.
--
BIM is a method of Replicating/Digitizing a Real Construction (Including Pre & Post Processes) in a Virtual Environment creating a Data which is Multi-Dimensional (Including Time).
--
Building Information Management - using the data after the modelling (design) process is complete. These definitions are not exclusive, they are complementary.
--
Building information modeling is the process of testing and optimizing design solutions in such a way that the sum of those myriad decisions are recorded and actionable by all interested parties in a single location (i.e. the building information model).
--
NBIMS Definition:
“A BIM is a digital representation of the physical and functional characteristics of a facility. As such it serves as a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle from inception onward.”
