BIM Flashcards
What is BIM?
BIM is an acronym for Building Information Modeling.
It is a highly collaborative process that allows architects, engineers, contractors, manufacturers, and other construction professionals to plan, design, and construct a structure or building within one 3D model.
It can also span into the operation and management of buildings using data that building or structure owners have access to (hence the Building Information Management). This data allows governments, municipalities, and property managers to make informed decisions based on information derived from the model— even after the building is constructed.
What are the benefits of BIM?
BIM, as a whole, refers to the process of all parties involved in the construction and lifecycle management of built assets, working collaboratively and sharing data. However, the true power of BIM lives in the “I” (information). All of the information gathered— from conception to completion— isn’t just stored, it’s actionable.
How is BIM information shared?
This information in a BIM model is shared through a mutually accessible online space known as a common data environment (CDE), and the data collected is referred to as an ‘information model’
What are BIM Levels?
Different levels of BIM can be achieved for various types of projects. Each level represents a different set of criteria that demonstrates a particular level of ‘maturity.’ BIM levels start with 0 and go to 4D, 5D, and even 6D
Can you describe what is involved in each BIM level?
Level 0 BIM: Paper-based drawings + zero collaboration
Level 1 BIM: 2D construction drawings + some 3D modeling
Level 2 BIM: Teams work in their own 3D models
Level 3 BIM: Teams work with a shared 3D model
Level 4 BIM: Time (scheduling of data)
Level 5 BIM: Cost (costs, budget analysis, budget tracking)
Level 6 BIM: Energy Consumption (LCC, etc)
Level 7 BIM: Asset Management/Facilities Management
What were the findings of the Global BIM Study?
50% of countries had regularity requirement for BIM or planned
60% had promotion of BIM
BIM framework for European countries to have standardised approach
What are the advantages of BIM for a QS?
- Visualisation
- Quicker take-off/quantity extraction
- Enables rapid revisioning - tracking changes
What are Irish policies in relation to BIM?
Digital Roadmap 2021
Outlines reduction in cost, reduction in programme and increasing construction exports.
What is a BEP?
BIM Execution Plan.
- Roles & Responsibilites
- Specific goals for BIM implementation (reducing costs, reducing delays, reducing RFI’s)
- BEP will be a guide for new project participants
- Understanding of teams knowledge and skills (what does project team need to do, what is current knowledge)
- Technological Infrastructure (softwares, how the interact, hardware requirements)
What are the risks with BIM?
- Bad models - model doesn’t work with rules of measurement
- Even bad models can inform risk profile and need for contingency
- Incorrect models - need to inform designers and giving feedback
- Rate of change in designs? BIM means designers can change their mind constantly - how will QS keep up? (Change anywhere is a change everywhere)
- QS’s cant keep up with the changes on a project
