21、ation Systems (BAS), Management explain the function and different elements of BIM and suggest which are most useful for telecommunications; and to recommend best practices for BIMs implementation and use. The development of the BICSI BIM Standard reflects the importance of maintaining a good balanc
22、e between the 3D modeling industry trends; the project basis of design modeling requirements; and the applicable Codes and Industry Standards. This Standard is based on the current BIM experience of many A/E firms and telecommunications industry experts. With the BICSI BIM Standards the ITS designer
23、 should be able to: Evaluate the benefits and requirements of BIM before engaging on a new project Better define the scope of work on a BIM project Have a reference point while designing for BIM Efficiently manage the BIM coordination Finally, the intent of releasing this document is to provide the
24、telecommunications industry a tool and Standard to meet the demands of the fast-paced BIM world. 1.3 Levels of Requirement Two levels of requirement are specified - mandatory and advisory. Mandatory levels generally apply to protection, performance, administration, and compatibility; they specify th
25、e absolute minimum acceptable requirements. Advisory or desirable criteria are presented when their attainment will enhance the general performance of the BIM system in all its contemplated applications. Mandatory requirements are designated by the word shall; advisory recommendations are designated
26、 by the words should, may, or desirable, which are used interchangeably within this standard. When possible, recommendations and requirements are separated to aid in clarity. 2 Scope The scope of this document will explain the usage of BIM objects provided by product manufacturers as well as the “le
27、vel of intelligence” integrated once these have been inserted to be part of the overall model. The “level of intelligence” term refers to the well defined Level of Detail (LOD) that each model is compromised by its components and design objects, (this will be elaborated further on this document). Th
28、is document also attempts to guide the ITS designer: During the development process of the 3D model and related modeling tasks Throughout the coordination with all disciplines to maintain standardization among all the different low voltage systems To deliver an efficient lean model ANSI/BICSI 003-20

Unless otherwise indicated, all standards and documents listed are the latest published version prior to the initial publication of this standard
30、. Parties to agreement based on this standard are encouraged to investigate the possibility of applying a more recent version, as applicable. Where equivalent local codes and standards exist, requirements from these local specifications shall apply. Where reference is made to a requirement that exce
31、eds minimum code requirements, the specification requirement shall take precedence over any apparent conflict with applicable codes.

35、 of BIM content. A category encompasses object groups, types, and instances that have related functions or are parts of similar systems. Examples of categories include “walls,” “doors,” “electrical equipment” “cable trays,” “security devices,” and “communications devices.” COBie (Construction Operat
36、ions Building Information Exchange): A standard, developed by the National Institute of Building Sciences in the U.S., for organizing building operations information. This information is used for building handover and facility management. Information is organized into a series of tables describing p
37、articipants in the buildings design and maintenance, floors in the building, spaces on floors, fixtures and equipment in spaces, periodic maintenance for equipment, spare parts suppliers, serial numbers, etc. Some of the information can be extracted from an architects or engineers BIM model, while o
38、ther information must be supplied by contractors or facility managers. content: Collectively models of devices, equipment, fittings, etc., which are suitable for use in BIM project models. content Model: A model, at the type or object group level of classification, depicting devices, equipment, fitt
39、ings, etc., which can be instanced into a project model at multiple locations. A content model can be either a product model, representing a specific product, or it can be generic, representing a device where the specific model has not yet been selected. firm: This refers to a consultant company, su
40、ch as an MEP “firm.” This will be referenced in the context of “an RCDDs firms content” generic: Non-manufacturer-specific content. Generic content is used by some firms in the early building design phases, because full requirements are not fully known at such an early stage. instance: The most spec
41、ific level of classification of BIM content, encompassing a single device, installed at a single location in a single project. model: A computer representation which simulates something in the real world. Depending on context, this term can refer to a BIM project model, individual BIM product models
42、 that are to be placed in BIM project models, generic content, or even a simple 3D (non-BIM) model of a geometric form. object: The representation of a building component in a BIM system. A BIM object includes the geometric form of the building component, as well as any graphic symbol used to repres
43、ent the component in plan drawings, non-graphical data such as manufacturer name or required voltage, and behavior of the component such as being able to be circuited to electrical panels or being able to be placed in a wall. object group: An intermediate level of classification of BIM content, more
44、 specific than a category, but capable of encompassing multiple closely related types that are similar in form and function. Examples could vary from manufacturer to manufacturer, but might include “two-post racks,” “angled patch panels,” “faceplates,” etc. NOTE: In programming vernacular, object gr
45、oups are also known as “families”. parameter: A data field comprising part of the definition of an object. Examples include “manufacturer,” “mounting height,” “voltage,” or “field of view.” product model: A piece of BIM content representing a product (or several similar products) from a particular m
46、anufacturer. project model: A BIM model of a building or other construction project, created by placing many instances of various generic or product models. reflected ceiling plan: A type of scaled drawing, common in architecture but uncommon in technology design, in which the underside of a ceiling
47、 is drawn as if the floor of the building was a mirror and the ceiling appeared reflected in it. rendering: Computationally producing a high-quality image of a model, usually by tracing the paths of many rays of light. Rendering often takes into account such factors as the position and characteristi
48、cs of light sources; colors, patterns, and bumpiness of surfaces in the model; reflections; transparency; translucency; and diffraction. Rendering (as opposed to simple shading) performed by high-end rendering software can produce images that are difficult to distinguish from photographs of the real
49、 world. scale-dependent: Having a graphical depiction whose plotted size is dependent on the scale of the drawing in which it appears, i.e., being drawn to scale. ANSI/BICSI 003-2014 4 scale-independent: Having a graphical depiction whose plotted size is always the same, regardless of the scale of the drawing in which it appears. For example a triangular symbol for a faceplate, which always appears 4.8 mm (0.19 in) on a side, regardless of the scale of the drawing. typ
