Work Packages
Modeled Work Packages
The Project:
 UW Housing Concrete
 Self-performed concrete work
 Design-bid-build delivery
 Lump sum, down-market bid
The Challenge:
 Accomplish tight schedule
 Prevent injuries and accidents
 Eliminate impacts and rework
 Beat aggressive labor budget
The Approach: Put the Model in Our Crews’ Hands
Approach

Prevent defects
Prevent accidents
Foster trust
The Approach: Combine the Model with Work Packages
Identifying Document Conflicts Virtually, Not in the Field
Using the Model’s Visualization to Plan the Work
Plan Forming and Pours
Identify Repetition for Prefab
4D to Fine-Tune Schedule
Quantities to Prorate Budgets

Tracking the Work Segments to Optimize Productivity
The Results:
 Exceeded budget goals
 Empowered crews
 Promoted safety
 Eliminated waste
 Promoted learning culture
 Ensured peak performance
Case Study
Bluebeam
Bluebeam
The Projects:
 362,000 Amazon Headquarters TI
 5,000 SAM TI
 250,000+ First & Main GSA
The Challenge:
 Efficient and timely drawing
updates
 Multitude of Subcontractors
including owner subs
 Large open floor plans
The Approach:
 Hyperlinked as-builts
 Electronic overlays
 Electronic punch list
The Technology:
 Bluebeam .pdf software
Case Study
SharePoint
SharePoint
The Project:
 Shorenstein property
 250,000+ First & Main GSA
 LEED gold TI
 5 month duration
 6 agencies over 12 floors
The Challenge:
 6 contracts with 6 separate
document streams
 5 architects, 4 engineers
 24hr turn on submittals and RFIs

Traditional Approach:
 6 couriered hardcopies
 Email / FTP sites
 Separate tracking/Log comparison
Waste:
 Delivery time
 Lost or inadvertent deletion of
Email
 Time spent tracking documents
 Working with the wrong file
 Confusing FTP sites

The Approach:
 Go digital
The Technology:
 Utilize SharePoint to organize,
distribute and track project
documentation
SharePoint

Live Shared As-builts
The Result:
 Faster document review
 Reduction in Cost Report turnaround time
 Effective Meetings
 Less paper use
“Using Lewis’ SharePoint as a portal between the design team and
contractor really helped to streamline the document exchange
process. Given the compressed timeline of the GSA projects, I don't
think we could have been able to meet the schedule without
SharePoint. I would gladly use it again and would look for ways to
implement a similar technology in my own organization.”
