week 7: BIM Flashcards
Building Information Modeling (BIM)
“the use of computers instead of drawings in building design”
Main goal BIM
not software development, but rather changing the way architecture, engineering and construction professionals work
BIM 1
“a process for generating and leveraging building data to design, construct and operate the building during its life cycle and allowing stakeholders to have access to the same information at the same time through interoperability between technology platforms” (NBIMS-US, 2015)
BIM 2
“a model encompassing the digital representation of physical and functional characteristics of a facility and serving as a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life cycle”
BIM 3
“management of the process by utilizing the information in the digital prototype to aid the sharing of information over the entire life cycle of an asset”
simulation and optimisation
create a model and simulate what is happening under certain conditions
CIty Information Modeling
addresses the challenges generated by the growing urban complexity
Level of Development (LOD):
defines the degree of geometric detail and alphanumeric information provided in a BIM, indicating its maturity and reliability
Little BIM
Refers to the use of specific BIM software by individual stakeholders for discipline-specific design tasks without model sharing or collaboration across stakeholders.
BIG BIM
Involves model-based communications between all stakeholders across the entire lifecycle of a facility.
Closed BIM vs. Open BIM
the first uses software products from one vendor with proprietary formats, while the second employs open, vendor-neutral data exchange formats.
Employer’s Information Requirements (EIR)
Specifies BIM project objectives, responsibilities, handover procedures, and data exchange formats.
BIM Execution Plan (BEP)
Details how bidders plan to meet EIR requirements, developed pre-award and refined post-award.
BIM as a product
This refers to a 3D model enriched with information, distinct from traditional CAD focusing solely on geometry.
BIM as a process
This emphasizes the management and exchange of information over time, involving collaborative use of semantically rich 3D digital building models throughout a project’s lifecycle.
