LEAN Construction Cost Estimating Drives Optimal Performance
LEAN Construction Cost Estimating
Detailed line item construction cost estimating is a core component of LEAN construction and measurably improved outcomes. Below are a few considerations when making the change to LEAN construction cost estimating and integrated project delivery:
- Shift from traditional silo-based estimating to collaborative / team-based estimating.
- Focus upon detailed line item estimating by discrete tasks.
- Use a common data environment (CDE), specifically locally researched unit prices organized via CSI Masterformat.
- Leverage document management, version control, access control, check-in/check-out, detailed change logging.
- Adopt LEAN processes and simplified user interfaces.
- Replace traditional design-bid-build and design-build with integrated project delivery.
- Select teams upfront and based upon best value.
- Embrace suggestions from those that do the actual work.
- Require early and on-going collaboration as well as initial and ongoing training.
- Address change management as a process based upon continuous improvement.
