B3 - Computers in Construction - LT #8 Flashcards
What is it called when 3D Models from different sub-contractors conflict using BMI
Clash Detection
List three advantages to designing buildings using computers:
Speed efficiency, cleaner more professional drawings, editing and revisions much easier.
How is a drawing made to a specific scale using a CAD Software?
Full-scale drawing of 1:1 & scaled when printing.
Describe what a library of symbols and objects is:
Pre-drawn building components & symbols can be copied into the drawings & manipulated.
How does computer use allow the designer to work more efficiently when drawing floor plans?
By copying and pasting, and allowing for working in layers.
What is the advantage of pictorial drawings?
Shows the appearance of the building and the land and construction connections in a manner that is easier for many people to envision.
List four typical libraries of symbols and objects that come with building design software:
Plumbing fixtures, electrical symbols, appliances, windows, doors, landscaping.
How do you multiply on a spreadsheet?
EXAMPLE: A2*B2 (1x2)
What is the spreadsheet formula for adding:
=SUM (CELL1:CELL2)
What does the * mean when used in a spreadsheet formula?
Multiply
Describe the main purpose for As-Built drawings.
To show where the electrical & mechanical systems were installed as well as any changes that were made during construction.
If a contractor damages municipal property at a job site, whose insurance would likely cover the damage?
Contractor’s insurance.
Does a contractor have to provide a warranty for an office building they constructed?
Only if the contract requires a warranty.
What is BIM?
Building Information Modelling
What is BIM?
Model-based technology linked with a database of project information. This means that a full 3D model of the building is generated from 2D conceptual drawings.
BIM drawings be generated from:
Orthographic drawings.
What’s an Electronic Plan Room?
Scaled down BIM.
Room is a digital space where plans, projects, bids, and other relevant info are housed.
What is CAD?
Computer Aided Design
What is CAD used for?
Industry standard for drawing building plans, drafting by hand can give a particular aesthetic to a set of prints but CAD is much faster for revisions and for placing hatchings, text, dimensions, etc.
Standard AutoCAD file formats:
DWF and DWG
