Architect’s Vision Flexible building and workplaces Central areas for interaction Ocean view Context

ArchitectEngineerCM New Design 1 Undeveloped circulation High Tech Clear structural grid Possible difficulty casting slope slab Excavation required for Auditorium High cost of the exterior (glass) Possible savings by exposing slab New Design 2 Good organization, elegant, interesting for good detail Structure integrated with architecture No visual intrusion to architectural components High learning curve due to the symmetry of the structure No excavation required for auditorium W a v e Matrix
