Transcript of AEC business model and design process

BIM is
2D drafting
modeling
characteristics
not BIM
3D geometry only,
no parametric intelligence,
models reconstructed from 2D
models that allow inconsistent views
why BIM
Fewer waist, less errors, less paper docs, greater flexibility, easier changes, better prefabrication support, higher productivity, less “money and time”, better end result due to early exploration of more options.
collaboration
Design - Bid - Build
owner

engineers

negotiate design, cost & time
it is not only the cost
1%
responsibility is here;
more collaboration, earlier
BIM friendly
InPro techincal report (in DropBox)
Act of creating the specifications for a product or process that best satisfies the design criteria (design constraints)
Design is:
engineering
(Lockhart)
(wikipedia)
Design is the planning that lays the basis for the making of every object or system
"How to do" = design
"What to do" = requirements
Graphics in design
visualisation
communication
documentation
"see" the problem
discover constraints
capture ideas
add details
keep it flexible for change
exchange of ideas early
easier for non-engineers
reduces ambiguity
recording the solution
paper --> digital
"part of the contract"
to be used for manufacturing
problem
ideation
refinement
analysis
implementation
documentation
InPro open information environment
informed choice!
modeling & analysis
analytical model
predicts future behaviour
descriptive model
represents the system - sketch
CAD model
a digital representation of physical and functional characteristics of a facility. A BIM is a shared knowledge resource for information about a facility, forming a reliable basis for decisions during its life cycle, existing from earliest conception to demolition. (NBIMS buildingSMART aliance)
digital

measurable
comprehensive
accessible

"all" stakeholders
more than geometry
who benefits
owners

symbolic value
transportable, versatile and malleable
when applied to new cotexts
classifications and typifications as
a basis of formal structures
tacit knowledge - encoded into technology and procedures
not easy transportable to new settings!!!
repetitive patterns of activity
material object consciously produced by human activity influenced by physical or cultural environment
regulative
normative
cognitive
