Q

what is BIM

A

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

Q

how does BIM impact a project and the cost of the project

A

the early integration and development of the stakeholders minimise the cost of changes and help keep projects on schedule and budget

Q

what is clash detection

A

the technique of identifying if, where, or how 2 parts of the building (plumbing, walls, etc.) interfere with one another

16
Q

What is 4D and 5D in BIM

A

4D = 3D model + schedule
5D = 3D model + schedule + cost

17
Q

what are the issues with road construction

A
  • long project duration
  • involvement of many stakeholders and huge cost
  • project management = 75% of time and costs
18
Q

what does CPM stand for

A

construction progress monitoring

19
Q

what is the definition of CPM

A

CPM is the repetitive process that consists of data collection, data analysis and project performance reporting to compare with the planned progress

20
Q

what are traditional data collection methods

A

manual text entry regarding progress (daily or weekly)

21
Q

what are current data collection methods

A
  • GNSS (Global navigation satellite system)
  • Total station
  • LiDAR scanner
  • Drones
22
Q

what are the real time benefits of automated progress monitoring

A
  • collecting data
  • progress tracking of the project
  • automated schedule updating of road construction
  • visualisation of road progress
  • coordination and communication with visualization
23
Q

what are the steps of CPM

A

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)

24
Q

what are some examples of automation in data collection techniques

A
  • bar code
  • QR code
  • RFID (radio frequency identification)
  • GPS
  • laser scanning
25
Q

why do contractors use 3D laser scanning

A
  • creates highly accurate 3D digital representation
  • can collect the as-is conditions
  • monitor progress of a project, create as-built models to augment missing design data
  • deliver a point cloud as a final project deliverable
26
Q

what are the advantages of scan to BIM

A
  • removes human error compared to traditional methods
  • data collected over short time
  • info can be shared faster
  • teams only need to visit the site once to collect data
  • can be used for various analysis
27
Q

BIM is a process that includes….

A
  • project collaboration
  • construction
  • operation and maintenance
    3D planning and design
28
Q

BIM drawbacks

A
  • logistical barriers
  • collaboration is limited by practices
  • changing defults can take time
  • large files
29
Q

what are 2 useful analytical tools for engineers

A
  • travel distance tool
  • occupant load calculations
30
Q

what does IFC stand for and what are some examples

A

industry foundation classes
- text based files
- model view definitions
