CM-BIM Unit 3 Flashcards
What does a 4D Model include?
Integration of time (scheduling) into the 3D Model.
What does a 5D Model include?
Integration of Cost (and quantities) into the 3D Model.
Another Term for Constructibility Review
Clash Detection or Spacial Coordination
Hard Clash
When two components physically overlap
Soft Clash
Where components violate space constraints imposed by code or design limitations without physical overlap.
BIM Addendum was created by…
ConsensusDOCS
Governing Contracts
Agreements between Owner, AE & Prime Contractors.
Affiliated Contracts
Subcontracts, Consulting Agreements, 3rd party contracts.
If there is an inconsistency between the BIM addendum and the Governing Contracts, which prevails?
BIM Addendum per BIM Addendum 1.11
“A three-dimensional representation in electronic format of building elements representing solid objects with true-to-scale spatial relationships and dimensions. A Model may include additional information and data.” - BIM Addendum 2.14
‘Model’
“Those aspects of the Project that (a) are to be modeled as specified in the BIM Execution Plan prepared pursuant to this Addendum and (b) have reached the stage of completion that would customarily be expressed by the Architect/Engineer in two-dimensional Construction Documents” - BIM Addendum 2.6
‘Design Model’
“A Model consisting of coordinated structural, architectural, MEP, and other Design Models designated in the BIM Execution Plan to be produced by the design team.” - BIM Addendum 2.9
‘Full Design Model’
“A Model that (a) consists of those aspects of the Project that are to be modeled as specified in the BIM Execution Plan prepared pursuant to this Addendum; (b) utilizes data imported from the Design Model or, if none, from a designer’s Construction Documents; and (c) contains the equivalent of shop drawings and other information useful for construction.” - BIM Addendum 2.2
‘Construction Model’
“A Model consisting of the federation of a Full Design Model and one or more Construction Models designated in the BIM Execution Plan to be produced by Project Participants.” - BIM Addendum 2.15
‘Project Model’
“A Model consisting of linked but distinct component Models, drawings derived from Models, texts, and other data sources that do not lose their identity or integrity by being so linked, so that a change to one component Model in a Federated Model does not create a change in another component Model in that Federated Model.” - BIM Addendum 2.8
‘Federated Model’
Ex:
- Full Design Model and Sustainability Analysis
- Construction Model and Constructability Analysis
- Arch Model, Structural Model, 4D and 5D Analysis
Project Participant
All parties that have Governing or Affiliated Contracts
Contributor
A project participant that makes a contribution, in other words a participant who actively adds data, information or other content, and derives information from project models.
What are some roles and responsibilities of the Information Manger (IM)
- Party responsible for coordinating BIM Information Managment
- Create, Delete, Modify and maintain users
- Assign, Delete and Modify Access Rights to users
- Apply security controls to restrict user access so that each user can modify their related information only.
- Track data entries to the model.
- Back-Up and Restore Data
- All around model security to prevent attacks and errors.
BIM Is Parametric, what does this mean?
When an object is modified in one model view, the parametric process inherent in the modeling software will automatically update all over views of that particular object to reflect the change.
Contractual Privity
Having a contractual relationship between parties. The lack of privity between the contractor and the designer in the typical DBB delivery method is what allows the contractor to assert design defect claims to the owner.
Spearin Doctrine
Court Ruling that states: “if the Contractor is bound to build according to plans and specifications prepared by the Owner, the contractor will not be responsible for the consequences of defects in the project plans and specifications.”
Indemnity (Definition)
A duty undertaken by one party to make good a loss, damage, or liability incurred by another party.
Indemnity (Function)
A contract provision that shifts the economic consequences of liability from one party to another, such that the indemnitor agrees to answer for the harm suffered by the indemnitee, creates indemnity.
Indemnitor
A party who answers for harm suffered by the indemnitee.
Inndemnitee
A party protected by another party. Indemnitor answers for harm suffered by indemnitee.
Duty of Ordinary Care for Design Professionals
A design professional is expected to exercise the same level of care that a reasonably prudent professional in that same geographic area would exercise when confronted with similar facts and circumstances.
Where are the professional duties of care and responsibilities typically described for design professionals?
The Governing Contract standard of care and indemnity provisions.
Is Risk Shifting and Privity of the Governing Contracts changed by BIM?
No, unless specifically changed required in the project contract or BIM Addendum.
