6D, 7D BIM, TIM and GIS Flashcards
Why do we need 6D/7D BIM?
10-20% cost on design and construction, 80-90% are life cycle costs of the building
In the past just focused on initial capital costs, using 6D/7D BIM allows a better understanding of whole life cycle costs (where higher proportion of money spent) which makes for better upfront decisions in terms of cost and sustainability
What is 6D BIM? (including its definition)
5D BIM + Sustainability = 6D BIM
Is the energy analysis of a building
What are the benefits of 6D BIM?
Complete and accurate energy estimates
Improved analysis of high performance facilities to learn lessons (thermal consumption, natural v artificial)
Can consider how proposals impact over whole lifecycle (by simulating outcomes and anticipated costs) - switches focus from initial capital costs to operational costs
Which analyses are included in 6D BIM?
Environment - in terms of reproduction and maintenance management capacity of natural resources
Economic - power to generate income and work
Social - well- being generator
What is 7D BIM? (including its definition)
6D + Facility management = 7D BIM
Used by managers in operating and maintaining facility through its life cycle (uses AIM)
What are the benefits of 7D BIM?
More efficient facility management as not bundles of lever arch files but all in one place
Allows participants to extract and track data such as component status, specifications, maintenance manuals and warranty data
FM can determine costs of these activities and create spend profiles
Learn lessons from BIM to avoid in future
Which analyses are included in 7D BIM?
Analysis of all outputs
Which types of infrastructure employ BIM to run projects?
Bridges, Roads and Highways, Rail and Transit, Aiports and Ports
What is TIM? Why use?
Tunnelling Information Modelling
Used as very complex system as involves the integration of multiple models
What are the components of TIM?
Tunnel Boring Machine Information - dimensions of shield and cutting wheel, material properties, machine performance and operating data
Tunnel Structure Information - dimensions of alignment, walkway, cable duct, etc, ‘this segement installed on this date’, type of material on lining segments (Youngs Modulus)
Ground Information - 3D soil layer geometry, soil layer properties, ground water level
Built Infrastructure information - dimensions of existing infrastructure in terms of area, stiffness, mass and vulnerability
What is GIS an abbreviation of? Definition?
Geographic Information System
Is framework for gathering, managing, analysing and visualising data
Why do we need GIS-BIM integration?
BIM does not have environmental data and so need GIS in order to analyse structure in the context of natural and built environmental
Need boundary between BIM and GIS to get insight into data like patterns, relationships and systems so that user can make smarted decisions
High end 3D content creation from simple 2D GIS data
How does BIM benefit from GIS?
Understand the impacts of a decision before during anf after construction for city planning
How does GIS benefit from BIM?
BIM provides detailing so the project can be assessed on any scale
What are the benefits of BIM-GIS integration?
Spatial Analytics - impact of design to surroundings before being built
Logistics and networks - transport of materials and movement of people
Ability to model and forecast - for construction and Emergency scenarios (eg in TIM)
Visualisation - creating maps, models and reports for board level audiences
