Presentation Outline Proposal • Introduction Existing structural solution optimal for Oslo, Norway • Existing Structural System • Proposal If the PwC building were located in the US it is likely design and construction methods would be different • Redesign of Gravity System • Redesign of Lateral System How would structural solutions change if the PwC Building were • Breadth Study hypothetically relocated to Boston, MA? • Conclusion Im age Courtesy of Oslo S Utvikling AS 4/ 14/ 09 Structural Option James Wilson

Presentation Outline Proposal • Introduction Major variables: • Existing Structural System • Local labor and design expertise • Proposal • Design codes • Redesign of Gravity System • Local material availability • Talent pool of contractors • Redesign of Lateral System • Design loads • Breadth Study • Conclusion Goal: Produce a design suitable for an office building in the Boston area Im age Courtesy of Oslo S Utvikling AS 4/ 14/ 09 Structural Option James Wilson

Presentation Outline Redesign • Introduction Gravity System: • Existing Structural System • Composite concrete deck with composite steel beams and girders • In comparison to concrete plank, it provides more flexibility for future modifications because • Proposal it is not limited by cutting of prestressed strands • Composite concrete deck is potentially lighter than concrete plank and therefore reduces • Redesign of Gravity System seismic loads, yielding a more economic structure • Redesign of Lateral System Lateral System: • Breadth Study • Steel braced frames • Conclusion • Compatibility with steel framing the of proposed floor system • Allow for potential reduction in schedule due to the simultaneous construction of gravity and lateral system • Explore steel as an alternative to the existing concrete design Im age Courtesy of Oslo S Utvikling AS 4/ 14/ 09 Structural Option James Wilson
