CM-BIM Study Class Guide Unit 1 with
Complete Solutions
3D - ANSWER-Thr combination of height,width and depth of a structure.
3D face model - ANSWER-It's the shell of the outside of a building. Holds as a smaller
file.
3D Modeling is - ANSWER-shoes dimensions and angles to visual objects
3D polygon mesh - ANSWER-Similar to a 3D face. Single flat plane.
3D solid model - ANSWER-represents the entire volume of an object.
4D - ANSWER-4D=3D+time(schedule)
4D - ANSWER-The integration of time(scheduling) into the 3D model.
5D - ANSWER-5D=3D+quantities(do not need 4D)
5D - ANSWER-The integration of quantities and cost into the 3D model.
A complete construction plan is a requirement because: - ANSWER-All project-related
activities are derived from the plan.
Benefits of BIM - ANSWER--improved communication
-improved coordination
-early detation of construtability issues.
-enforced consistency
-"what-if" analysis
Bim - ANSWER-Building information modeling
BIM for infrastructure and civil engineering: - ANSWER-applies to streets, bridges,
airport, runways
BIM improves communication and information(T/F) - ANSWER-True
BIM is - ANSWER-Efficient workflow,data re-use,foundation for optimizing project
delivery.
BIM is a business driven ed method(T/F) - ANSWER-True
BIM is a business proposition not a technology decision.(T/F) - ANSWER-True
, BIM is a process and not a software package(t/f) - ANSWER-True
BIM is a process and not software(t/f) - ANSWER-True
BIM is a process of collecting,manipulating and analyzing information, not just software
or technology. (T/f) - ANSWER-True
BIM is Date reuse and not data recreation. (T/F) - ANSWER-True
BIM is truly about data(t/f) - ANSWER-True
BIM Process Map - ANSWER-Help with decisions needed to be made. Huge graph with
the processes.
BIM uses- - ANSWER--construction sequencing planning, phasing plans, logistics
-Design Visualization
-Facility Management
-marketing Presentation
-optional analysis(what ifs, shows different scenarios)
-prefabrication
-scope clarification
-spatial coordination(highlighted areas where installed materials interfere spatially)
-sustainability
-wall-throughs and fly throughs
BIM(noun) - ANSWER-An electronic, virtual representation of a facility,which in many
cases comprises a 3D representation of the facility.
BIM(verb) - ANSWER-The process of creating,managing and using BIM to design a
facility,communicate and refine the design, and plan and optimize the construction
effort.
Characteristics of a good conceptual estimating model: - ANSWER-Cost drivers:
variable costs, affect overall project cost, design decisions impact. Easy to modify:
alternatives Represent building systems in a balance way: Show construction costs of
MEP Systems. GEOMETRY DRIVEN VARIABLES
Clash Detection - ANSWER-a process for effectively identifying unintended material or
system interferences in a 3D project model
Computer-assisted virtual environments(CAVES) - ANSWER-A room like with Vr
googles that you are in an empty room to see virtual layouts.
Conceptual Estimate - ANSWER-balance between the accuracy and coverage of all
possible options,.
