Lean Construction Institute (LCI) teamed with McGraw-Hill on a survey of the construction environment regarding the use of Lean Construction across the industry.
The final survey results are captured in a SmartMarket Report titled;
Here are few highlights from the full (60-page) study:
Lean construction offers an alternative that allows companies to thrive in any economic conditions; in combination with BIM and pre-fabrication, Lean makes firms more competitive and yields strong business benefits.
Surveyed companies cited such benefits as higher quality construction, greater customer satisfaction, greater productivity, and improved safety.
Advanced modeling: BIM has become an increasingly common tool among GCs, and some emphasized that advanced uses of BIM facilitate Lean efforts; when planning and detailing work. In particular, GCs noted that detailed modeling is central to coordinating and detailing offsite prefabrication.
It is noteworthy that, even among the Lean practitioners, none of the respondents report using 4D schedule modeling or 5D cost modeling. The Lean experts interviewed in the in-depth interviews frequently mention the importance of BIM to implementing Lean at their firms. (see page 17)
While a few of these experts do report doing 4D schedule modeling, the larger survey results reveal that this is still a highly limited practice.
Two things were perceived as continuing challenges:
1) education about Lean and the need for and benefits of increasing efficiency are lacking in the industry as a whole, and
2) technologies currently in place could be much improved to support a more highly collaborative environment.
