Building: Metropol Parasol
Location: Seville, Spain
Construction years: 2005-2011
Architect: J. Mayer H. Architects (Jürgen Mayer-Hermann)
Structural Engineer: Arup

The Metropol Parasol has displayed a new innovative way to use timber in construction.  First of all, it is the largest wooden structure in the world.  The building spans over 10,500 square meters, encasing 5,000 square meters and standing about 26 meters high.  Not only that, but it also displays complex geometry rather than rectangular.  This waffle-like timber structure serves as a canopy while also housing multiple bars and restaurants.  The site called for a structure that would not ruin the historical grounds.  Therefore, Roman and Moorish ruins discovered on site are displayed to the public on a floor underground and the structure itself only connects to the ground in a few locations.  After many years of delay in construction, in order to accomplish these goals and make the structure stand, the timber and steel was bonded with high-performance polyurethane resin, a foam seal.  This “glue” was tested to ensure it could withstand the highest possible temperatures.  The structure stands on a concrete foundation with an interior of concrete, steel, and granite.

Building: Cowboys Stadium
Location: Arlington, Texas
Construction years: 2005-2009
Owner: City of Arlington
Architect: HKS, Inc.
Structural Engineer: Walter P Moore and Campbell & Associates
General Contractor: Manhattan Construction

The stadium of NFL’s Dallas Cowboys is the largest dome in the world.  The roof has an area of 660,800 square feet with the highest point at nearly 300 feet above the field.  The stadium is centered about two main steel arch box trusses, anchored to the ground on each end lying 1,225 feet apart.  Two of the large panels connecting these trusses are retractable, creating an opening of 104,960 square feet in twelve minutes.  The world’s largest operable glass doors are located at each end zone of the stadium, spanning 180 feet wide and 120 feet high.  The main exterior shell of the building is fritted glass curtain wall with aluminum mullions.  This curtain wall is supported by vertical, rectangular steel tubes placed every 8 feet along the perimeter.  The arena seating is supported by over 700 concrete piers that are drilled 20 to 80 feet into the ground.  Combining these elements has made an aesthetically pleasing building that well serves its function.

2005: Release of Revit Structure

Innovation:  Revit Structure
Location: United States
Year:  2005
By: Autodesk

Revit Structure is Building Information Modeling (BIM) software produced by Autodesk.  Shortly after the release of Revit Architecture, Revit Structure was first released in 2005.  There is much overlap in the two programs, but major differences are seen.  In Revit Structure, purely architectural elements such as color schemes, ceilings, rooms, and decal are not included.  Instead, Revit Structure favors the engineer, allowing access to rebar, trusses, loads, and the ability to run an analysis on the structure.  As in Revit Architecture, structures are built in members, not with lines.  The tools contained in each program cater to the knowledge of the intended user.  With the release of Revit Structure, structural engineers were able to work with more complicated and intricate designs since the computer was now able to analyze each member.  The engineer no longer needed to perform hand calculations, which saved a massive amount of time.

Innovation:  Revit Architecture
Location: United States
Year:  2004
By: Autodesk

Revit Architecture is Building Information Modeling (BIM) software produced by Autodesk.  Revit was first released by Revit Technology Corporation in 2000.  At this time, its main competitors were ArchiCAD by Graphisoft and Microstation by Bentley Systems.  Revit was bought out by Autodesk in 2002.  The 2004 release was the first truly comprehensive BIM software, named Revit Building.  The name was changed to Revit Architecture after the 2006 release.  This software was the first of its kind, fully incorporating BIM into the 3D modeling program.  Rather than building with lines, Revit operates using members; for example, a door or window is all one piece, the designer simply specifies the material and dimensions.  Further, the creation of Revit Architecture allowed architects and building designers to create a task schedule directly linked to the respective parts, to easily identify collisions within the design, to link the members to specific products that will be purchased, to determine the occupancy level and ventilation loads for spaces, and overall to capture every aspect of a building in one database.
