Why 3D Models will Drive the Construction Process

Why 3D Models will Drive the Construction Process

Terry Bennett, Sr. Industry Manager

 

In an industry conversation with Tim Tometich, GPS division manager, McAninch Corporation at their offices he stated: “Traditional processes of paper plans, stakeout sheets and grade stakes used to take up to a week to implement. Now with GPS machine control and 3D models from designers, that same size project can take hours. This allows us to reduce fuel consumption, idle time, air pollution including greenhouse gas emissions, and material waste while providing our clients with a more accurate product. We believe that starting from 3D models to drive the construction process is the way of the future.” Why should all heavy contractors care about models and BIM – well two very important aspects – time and cost.

 

Here is what McAninch has been able to do achieve:

·         Increase productivity by up to 50 percent

·         Cut redundant survey costs by up to 90 percent

·         Reduce fuel consumption (and associated GHG emissions) by 43%

·         Grade check accuracy of 98% vs. traditional staking of 45%

 

What have others been able to achieve:

·         Contractors who recently invested in GPS machine control paid for their systems within 13 to 18 months

·         70% of respondents report that GPS machine control increases their opportunities to bid contracts

 

The Net Net:  Models + GPS Machine Control = more efficient operation, reduced material use and waste, lower fuel costs, and more accurate results.  It’s a way to green heavy construction!
