PERFECTION AT THE CONNECTION BIM in the field, bringing an assembly line approach to modern construction Christopher Heger LSSBB, Turner Construction

BECAUSE OF BIM Every object on an Assembly Line Construction Project: • • • • •

Has a description of WHAT it is. Has a location of WHERE goes. Has a time of WHEN is it installed. Has a person WHO installs it Has a PROCESS CHART associated with it’s installation movement and installation process. • At a faster TEMPO Perfect information at the point of attachment equals “Perfection at the Connection”

BIM is bringing Design, Owner, and Contractor together in common platform with a common language. “INTENT” is becoming “UNDERSTANDING”

Built to Design As-Builts are a Measure of Failure. Failure of construction to build the Design or Failure of the design to be buildable.

“Perfection at the Connection” = Perfect Information at the point of attachment. Skilled Crafts can focus on attachment and quality, just like workers at Rolls Royce #BIMForumED

Performance Indicators Target Zero Waste •

Green by focusing on nothing coming to the site that will go in a landfill

•

Prefabricate units off site to the largest metric feasible

•

Cut down on standard waste on a site which can be 68%

•

Cut down on effort to move it in and out of the project 10-30%

•

Increase productivity and safety through a cleaner more organized site

Frank and Lillian Gilbreth: “The One Best Way” at the Object

1885 Brick Mason

6000 years of interchangeable parts

1891 Reduced the steps in laying brick from 18 to 5 Increased the # of bricks installed per hour from 125 to 300 3 motions x 2 seconds each = 6 seconds 500 times per day x 6 seconds = 50 minutes per day 5 work days x 50 minutes per day= 4.16 hours a week 10% improvement on a 2 second change. #BIMForumED

BIM gives construction the ability to see pieces as interchangeable parts. Create uniform and tighter tolerances

If Motion is not valued it cannot be improved -Gilbreth

It acts as the pawl of a ratchet wheel permitting forward motion, but preventing retracing of steps already taken. #BIMForumED

Conclusion Christopher Heger LSSBB [email protected]

BIM is changing the way we work and think about construction. The goal of perfect information means building in Less Time, with Less Waste, with Greater Quality, and Greater Value. https://turnerbim.box.com/BIMForum #BIMForumED
