GSA, Edward Zorinsky Federal Building, Renovation

Omaha, Nebraska

Owner:
US General Services Administration

Leo A Daly provided complete renovation design for the nine-story Edward Zorinsky Federal Building, including replacement of the building facade and heating/cooling, plumbing, lighting, and electrical systems. Sustainable design features include reuse and revitalization of the structure; installation of energy-efficient windows, sun-shelves, and sun-shade devices; use of recyclable and recycled renovation materials; rooftop rainwater collection as greywater; photo-voltaic rooftop solar collectors; and installation of a highly energy efficient HVAC system. Working with Applied Research Associates, Inc., Leo A Daly provided a blast analysis and design solution following US Department of Defense criteria. Analysis showed that progressive collapse would result if a perimeter column were lost due to blast. To prevent this, a continuous steel girder was designed to span two bays to support the floor due to a lost column.
