BIM (building information model) - ANS-multi dimensional model of the traditional
two-dimensional plans and specs
it holds vital info about every component of the model (model linked to a database), good for
visuals/presentations - ANS-How is BIM different from CAD 3D models?
benefits of BIM - ANS-building project in virtual world, allows contractor to work out glitches
behind a computer vs in the field, allows contractor to link schedule and estimates
see where laydown areas and deliveries would work best, info can be loaded directly into
equipment - ANS-How can BIM help w/ layout and fieldwork?
helps to isolate, analyze, and optimize any area of the project, cuts down schedule, raise quality
and lower cost - ANS-How can BIM help with prefabrication?
two basic approaches to implement BIM - ANS-central repository approach and distributed
repository approach
central repository approach - ANS-often considered impractical. it merges all info from
estimating and scheduling into one database
distributed repository approach - ANS-utilized by most subcontractors. this process links the
model to a collection of separate databases with independent programs
