Week 5 - BIM Flashcards
what is the traditional linear building process
client
architect
engineer
contractor
consultant
fabrication
operations
what are the limitations of the traditional process
- lack of communication/miscommunication between stakeholders
- It is hard to make important changes later on
- inefficient analyses and assessment
what are some errors that can occur in the traditional process
unanticipated costs
delays
lawsuits
what is the main saying in construction
“Pain is an old friend”
what was the first digital solution
autocad1 (1980s)
what does BIM stand for
Building information modeling
what is BIM
a digital representation of the physical and functional characteristics of a facility. it is the process of creating and managing information about a construction project across the project lifecycle
how is BIM different to the traditional model
BIM is an inclusive process where design and documentation can be done simultaneously
what are some BIM design processes
- architectural
- structural
- MEP (mechanical, electrical, plumbing)
how does BIM impact a project and the cost of the project
the early integration and development of the stakeholders minimise the cost of changes and help keep projects on schedule and budget
what are some BIM based analysis that can be done
- structural
- energy simulation
- fire safety simulation
- health and safety during construction
- heating-cooling load analysis
- clash detection
what is clash detection
the technique of identifying if, where, or how 2 parts of the building (plumbing, walls, etc.) interfere with one another
what project phases can BIM be used for
- design
- construction
- operations and management
what is the purpose of the BIM platform
it’s about having the right info given to the right people at the right time
what are the dimensions of BIM
3D, 4D, 5D, 6D, 7D
What is 4D and 5D in BIM
4D = 3D model + schedule
5D = 3D model + schedule + cost
what are the issues with road construction
- long project duration
- involvement of many stakeholders and huge cost
- project management = 75% of time and costs
what does CPM stand for
construction progress monitoring
what is the definition of CPM
CPM is the repetitive process that consists of data collection, data analysis and project performance reporting to compare with the planned progress
what are traditional data collection methods
manual text entry regarding progress (daily or weekly)
what are current data collection methods
- GNSS (Global navigation satellite system)
- Total station
- LiDAR scanner
- Drones
what are the real time benefits of automated progress monitoring
- collecting data
- progress tracking of the project
- automated schedule updating of road construction
- visualisation of road progress
- coordination and communication with visualization
what are the steps of CPM
as-built (actual progress) data collection -> data process and data analysis to determine project progress -> comparission of As-built progress vs planned progress -> communication/reporting
(AS A CYCLE)
what are some examples of automation in data collection techniques
- bar code
- QR code
- RFID (radio frequency identification)
- GPS
- laser scanning
