  • 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 Results:

  • Exceeded budget goals

  • Empowered crews

  • Promoted safety

  • Eliminated waste

  • Promoted learning culture

  • Ensured peak performance


Bluebeam l.jpg

Case Study

Bluebeam



Slide49 l.jpg

  • 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


Slide50 l.jpg

  • The Approach:

  • Hyperlinked as-builts

  • Electronic overlays

  • Electronic punch list

  • The Technology:

  • Bluebeam .pdf software


Sharepoint l.jpg

Case Study

SharePoint



Slide53 l.jpg

  • 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



Slide55 l.jpg

  • 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


Slide56 l.jpg

  • The Approach:

  • Go digital

  • The Technology:

  • Utilize SharePoint to organize, distribute and track project documentation
















Slide71 l.jpg

  • 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.”
