CHOP 5.6 - BUILDING INFORMATION MODELING (BIM) Flashcards
Building Information Model
“Building Information Models contain unambiguous digital facility information for the purposes of communication and collaboration between all different trades and stakeholders (Architects, Engineers, Contractors, Owners and Operators) in the construction sector.”
Building Information Modeling
“Building Information Modeling processes (BIM processes) can be viewed as the collaborative practices of creating, using and maintaining models in support of the lifecycle of a facility.”
Interoperability
nteroperability is defined as: “the ability for two (or more) systems or components to exchange information and to use the information that has been exchanged.”
Collaboration
Collaboration is at the centre of BIM’s success. BIM collaboration includes communication amongst all the parties involved, together with a universal approach to collaborative design, realization and operation.
Level of Development (LOD)
LOD has multiple definitions, but essentially describes the stages of evolution of design
LOD 100
Elements are a generic representation, giving the viewer a basic idea of existence but no idea about size, exact shape or orientation;
LOD200
A representation of a rough idea of elements’ size, location in the facility, etc., but with much approximation;
LOD 300
This shows the specific geometric size of the element and orientation, location, and quantity used across the facility;
LOD 350
A revision of LOD 300 depicting precise information about how the component will be connected to the nearby elements;
LOD 400
Sufficient information to fabricate the component with individual holes and weld sizes;
LOD 500
The fully-developed design, showing the operational geometry of the component, the stage of installation of the component with duly verified information such as manufacturer details, dates, part, and model number, etc.
The following are keys to successful BIM implementation:
1) planning: a thoughtful BIM strategy agreed to by leadership;
2) transparency: share the strategic BIM plan with the entire office. Transparency will help solidify expectations office-wide;
3) learning: developing a culture of learning is very important.
Role of the System Integrator
The System Integrator is responsible for the systems and protocols of data and information exchange.
Working with design staff, the responsibilities of the System Integrator include the development of policies about access and editing control, development of templates, and structuring libraries of shared digital content.
Role of the BIM Manager
The BIM Manager is responsible for the configuration of the model for a given project and the enforcement of policies controlling viewing, editing, merging, and releases of the master model.
A BIM training program should build on the five phases of learning program development:
1) analysis;
2) design;
3) development;
4) implementation;
5) evaluation.
Analysis of training needs includes taking an inventory of:
1) learners’ current knowledge and capabilities;
2) the body of knowledge to be acquired and the capabilities to be demonstrated by the learner;
3) identifying the gap between the two;
4) analysis of the learner’s context, i.e., available time, preferred delivery modality, etc.
Implementation of the program of instruction:
1) Train the instructors
2) Prepare the learning with pre-learning information and assessment
3) Prepare the learning environment
Whether BIM is implemented as the first design and production system or whether the office is transitioning from CAD drawing to model building, the following is a condensed list of the learnings that must take place in order to support smooth office functions:
- network, server, and workstation configuration;
- server setup and file organization;
- BIM libraries structures;
- basic model building;
- single or federated model configuration;
- drawing setup and printing/plotting;
- project planning, work assignment, and reporting system;
- review and approval procedures;
- hand-off procedures.
openBIM
In selecting an authoring platform with which to build the model and add attributes, key considerations are interoperability and collaboration, particularly for large projects with numerous stakeholders creating and using the model(s).

Culture
Organizational culture is the sum of an organization’s structure, strategies, decision-making, stories and rituals. In an organization with a strong culture, employees know the behaviour that senior management expects of them and how to respond in given situations.
