Building Construction Industry Challenges

In the field...

• The paper plans come out
  - Leaving the 3D Model in the office
• Traditional manual methods are often used for layout
  - Manually scaling distances and calculating angles from plans
  - Turning angles with theodolites and pulling tapes to measure distance

Project Lifecycle and BIM

• Traditional project delivery tends to focus the greatest amount of effort during the construction documentation phase
• At this point in the project lifecycle, much of the design has already been developed, but input from the construction team about costs and schedule lead to significant design changes
• Trend – integrated project delivery promotes greater collaboration earlier in the project lifecycle
• Emergence of BIM technology is further promoting this shift as collaborative modeling tools become available – savings valued ~3% of the entire construction value
