Flashcards in CM-BIM Unit 2 Deck (37):

What is Micro BIM?

Micro BIM refers to the adoption of BIM on a specific Project.


What is Macro BIM?

Macro BIM refers to the adoption of BIM as a corporate strategy for multiple if not all projects.


What is an example of a direct benefit of using BIM?

Less change orders due to coordination.


What is an example of an indirect benefit of using BIM?

Field work continuing uninterrupted due to coordination.


What is an example of a tangible benefit of using BIM?

The costs saved by eliminating "x" number of change orders.


What is an example of an intangible benefit of using BIM?

The confidence that the team develops in the model, when it proves to accurate, as evidenced by identifying issues virtually.


What is interoperability?

The capability of different programs to exchange data via a common set of exchange formats, to read and write the same file formats, and to use the same protocols.


Categories of BIM Software: Conceptual

Normally the first stage. This is where the idea for the project develops. This could be anything from a sketch on a napkin to a fully developed model. May also be used as a "go"/"No Go" decision for the project.


Categories of BIM Software: Create

This is where the BIM Authoring tools are used. There are different authoring tools for different trades, there is no single solution.


Categories of BIM Software: Predict

This is where BIM software tools can be used to run simulations on the model to predict its operability such as lighting, thermal, and energy performance.


Categories of BIM Software: Validate

This is where BIM software can be used to test code compliance or other standards/guidelines.


Categories of BIM Software: Review

This is where BIM software can be used to review for accuracy or examine specific features within the model. This is often done via "Walk-Throughs," "What-If" decisions, redlining and marking up the model.


Categories of BIM Software: Delivery

These tools allow the smooth transfer of a model with an audience so the recipients don't have to purchase the authoring tools to be able to stay abreast of the project. (Autodesk DWG True View).


What are Preliminary Design Tools

Also called conceptual design tools which overlap the pre-design and schematic design phases. Tools in this class use known project data to develop models. These models are used for conceptual estimates, conceptual energy use etc.


What are Authoring Tools?

There are many different types of authoring tools based on the various trades. All authoring tools are intended to create models and are used in all phases of construction and can be utilized by Designers, GC/CM, Specialty Contractors and Fabricators.


What are Analysis Tools?

Analysis tools are used to predict, validate, review, and deliver the data-rich BIM. They are used to evaluate building performance, check code compliance, reviewing constructability, etc.


What are shop drawing & fabrication tools?

Currently these tools are primarily used to provide spacial requirements for on-site installation of various systems. In the future these tools will be used to fabricate off site for plug-in installation as needed, used for materials ordering and construction resource planning.


What are Model Review Tools?

Model review tools are used to overlay the various project models into a federated project model for spacial coordination (class detection). (i.e. Navisworks).


What are construction management tools?

These tools are used throughout the entire project form the schematic phase thru construction and even facility management. The primary function is to create a collaborative environment for all project participants to get involved in the project focused environment.


What are the advantages and disadvantages of FTP sites?

File Transfer Protocol, low cost collaboration & communication tool. Disadvantages includes limited customized user control, lack of transaction audit trail and requires training.


What are the advantages of Web-Based Collaboration Tools?

Easy access for participants, ability to customize interface, and often creates an audit trail. The main disadvantage is the price of services.


What are the advantages/disadvantages of Client Based Application Tools?

Rich user interface allows for efficient and fast interaction, ability to compress files before transfer. Disadvantages: Software must be loaded on every participants computers and can create problems with IT and firewalls.


What are the advantages/disadvantages of Cloud Based collaboration?

Defiinition: Ability to share information on external file storage that is accessed via the internet.
Advantages: Can be accessed from any web enabled device, ability to customize access for participants, and creates and audit trail.
Disadvantages: must have an internet connection, potentially high prices.


What does optimize for multiple dimensions mean?

This means do not design to optimize one system or each system separately, design for the Theoretically Optimal Building Design by combining different design variations of multiple systems to come up with the best overall design.


What do we expect to learn from Architectural analysis tools?

We want to check the quality of the design versus the design specs, owner requirements, and Code Compliance. We want to analyze the space planning, validate proper arch elements are used in the right places, and ensure there are no duplicate objects.


What do we expect to learn from structural analysis tools?

We want to be able to check the structural integrity of the design model by analyzing for load bearing capacity, seismic tolerances and load tolerance at connections, as well as interfacing with CIP and Pre-Cast Concrete.


What do we expect to learn from Energy/Analysis tools?

We want to check the design model for a wide range of energy/environmental behaviors or factors. We want to know if the project can be built and operated within allowable cost and performance constraints.

What are Object Enablers?

An application written by a software developer that allows its custom or proprietary objects to be viewed in a different application environment. Object Enablers are often available free of charge on the website of the relevant application developer.
