facility
physical structure (asset) or installation, including related site, works, serving one or more main purposeNOTE: Typically, a facility will require management over part or all of its life cycle. The term “facility” in BS 8536 is often used to refer to buildings or complexes, encompassing the physical structure and the services required to support its […]
life cycle
stages and activities spanning the life of the system from the definition of its requirements to thetermination of its use, covering its conception, development, operation, maintenance support and disposal NOTE 1 Adapted from IEC 61508 and ISO/IEC 15288:2008, definition 4.10.NOTE 2 Adapted from ISO/TR 18529:2000, Clause 3.

exchange requirement (ER)
defined set of information units that needs to be exchanged to support a particular business requirementat a particular process phase (or phases)/stage (or stages) BS EN ISO 29481-1:2017
consensus
general agreement, characterized by the absence of sustained opposition to substantial issues by any important part of the concerned interests and by a process that involves seeking to take into account the views of all parties concerned and to reconcile any conflicting arguments NOTE Consensus need not imply unanimity. [SOURCE: ISO/IEC Guide 2:2004, 1.7] PAS […]
data sheet
data template that is populated PAS 14191:2020
data template
schema providing a data structure used to describe the properties of objects NOTE The relevant scope of the data template should be used together with the term “data template”. E.g. a data template for a product should be named “product data template”. A data template for a system should be named “system data template”, etc. […]
delta exchange
exchange of only changed information between two synonymous sources PAS 14191:2020
major change
change that affects the meaning, function or intended useNOTE Definition applies to properties and groups of properties.PAS 14191:2020
metadata

ELI5-S1: BIM Basics E6: Metadata explained Understanding Metadata in Building Information Modeling (BIM) Metadata provides critical information about an item’s content, making it easier to locate and work with specific data instances. For example, an image’s metadata might include details such as color depth, resolution, and creation date. Similarly, a text document’s metadata can contain […]
minor change
change that does not affect the meaning, function or intended use NOTE 1 Definition applies to properties and groups of properties.NOTE 2 Examples of this type of change are new translation, rectification of typographical errors.PAS 14191:2020
property
inherent or acquired feature of an item[SOURCE: BS ISO 6707-1:2017, 3.7.1.3] NOTE Examples include thermal efficiency, heat flow, sound reduction index and acoustic power level.PAS 14191:2020
progression
the process of developing gradually towards a more advanced state.
Detail Maturity
Scale of the amount graphical detail
Information Maturity
a current state of development of an organisation to utilise information in an advanced strategic manner to increase productivity, measured against an assumed optimal state
Permitted Purpose
A submittal state defining the intent or suitability. Permitted Purpose means any purpose related to the Works (and/or (without limitation) the construction, refurbishment, extension, operation, management and/or maintenance of the Works) which is consistent with:(a) the applicable Level of Information Need of the relevant Material;(b) the applicable status code of the Material and the information […]
Approval
A state used to approve information for the permitted-purpose
Model Production Delivery Table (MPDT)
An MPDT its old PAS 1192 term, the MPDT defines who produces what, when and to what level of detail. The recent publication of ISO 19650 standards does not include the term. The situation does introduce a level of confusion as some think that MPDT is now called the Responsibility Matrix in ISO. “High-Level Responsibility […]
Digital Plan Of Work (DPoW)

Digital Plan Of Work (DPoW) forms a framework that supports informed and consistent decision making by project teams, at each work stage, helping to deliver agreed and reliable information. The National Building Specification Digital Plan of Works (DPoW) is an online tool that facilitates the process of Building Information Modelling (BIM), in particular relating to […]
Enabling Tools
Tools that help design, develop, deliver, and maintain the built asset. You may require a number of different enabling tools for specific tasks and functions. https://www.thenbs.com/knowledge//periodic-table-of-bim
People
An element of a BIM strategy which is often overlooked. Clear communication is required as to why and how you intend to implement BIM and gain support by engaging BIM champions, as well as getting support from senior management. BIM implementation requires changes in the process so make sure that you share success among the […]
BIM STRATEGY
a plan of action designed to achieve a long-term or overall aim. Definitions from Oxford Languages Required to define and understand what your company is trying to achieve with BIM. Consideration is required to the method and timing of the implementation strategy – including supporting foundations, processes, technology, tools and people required.
engineer
a person who designs and superintends the carrying out of civil engineering works, structures of buildings, installation of services, or who maintains such civil engineering works, structures or services https://www.iso.org/obp/ui#iso:std:iso:6707:-2:ed-3:v1:en:term:3.8.25

BIMwash
The term BIMwash is derived from Whitewash, “a cheap white paint or coating of chalked lime used to quickly give a uniform clean appearance to a wide variety of surfaces”. Metaphorically, to whitewash means to “gloss over or cover up vices, crimes or scandals or to exonerate by means of […] biased presentation of data” (Encyclopaedia Britannica, 2003). In […]
