Unit-1 Flashcards
Building Information Modeling (BIM)
is the process of generating and managing a Building Information Model through the use of three-dimensional, intelligent design information.
Building Information Model
An electronic, virtual representation of a facility, which in many cases comprises a 3D representation of the facility.
Design-Bid-Build (DBB)
A method of project delivery in which the owner procures a design and bid package from an independent designer; uses competitive bidding ; and selects a constructor on the basis of the low bid received from a responsible constructor.
Design-Build
a method of project delivery where one firm assumes responsibility for both the design and construction of the project. DB can promote a interdisciplinary team approach
Interoperability
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
Integrated Project Delivery (IPD)
a collaborative approach that brings designers, engineers, CMs, trade workers, suppliers, and fabricators together early in the project to facilitate decision making and optimize project results
Lonely BIM
Model is not developed collaboratively and the construction team must develop its own model based on the information provided by the design team in construction documents.
Parametric
Software objects that reflect the real-world behaviors and attributes of construction materials, equipment and assemblies. Objects possess characteristics of construction materials, equipment and assemblies and the interrelationship and interaction between them. Consistent relationships between elements as the model is manipulated.
Parametric modeling
Parametric models are object-based rather than line-based. This allows them to have all of the objects in a model be adaptable by simply changing the reference file for that object; it also allows all of the views to be changed automatically when one is changed.
Software as a Service (SaaS)
Software and services provided either by subscription or pay-as-you-go model. Could also be charged by time (processing units). This is one example of Cloud computing.
Solid modeling:
Solid modeling allows users to easily create and edit 3D solid shapes in an arbitrary way.
Virtual Design and Construction (VDC):
The use of integrated multi-disciplinary performance models of design-construction projects, including the product (i.e., facilities), work processes and organization of the design-construction-operation team in order to support explicit and public business objectives. “VDC models are virtual because they show computer-based descriptions of the project.”
BIM shared vision
Everyone is focused on the project, rather than solely on their particular specialty or required tasks. BIM is about developing an inclusive environment for the entire life cycle, not just for the phase of the project of a particular trade.
The central point is that BIM is
a process of collecting, manipulating and analyzing information, not just software or technology.
