AEC Pros

A rooftop observation deck spans three hotel towers and creates a dramatic element in the Singapore skyline.

The SkyPark is an architectural masterpiece that rests atop the three 55-story hotel towers of the Marina Bay Sands mixed-use resort in Singapore. Recognized as one of the world’s largest public cantilevers, the SkyPark defies gravity as it extends 213' beyond the towers and boasts incredible panoramic views of the Singapore skyline, the South China Sea, and Marina Bay.

Welcome to the On Site channel’s first Construction Administration Column. David A. Todd, P.E., CPESC, gives his opinion on a common issue with shop drawing approval.

Columnist David A. Todd, P.E., CPESC, has 37 years of experience in the architecture, engineering, and construction (AEC) industry and has performed much construction administration during that time. He will answer questions from our readers or from his own practice and will provide answers based on his understanding of the construction process and administration of the construction contract. The focus will be on the customary duties of the owner, contractor, and design professional as typically described in the contract documents.

The ultimate in green design is nature itself. Here, experts explain the concept of biomimicry and give examples of how buildings can take inspiration from natural systems.

If the past 3.8 billion years have taught us anything, it’s that nature knows best. The field of biomimicry is built upon this premise, drawing inspiration from nature’s systems and processes to find solutions for human needs: “innovation inspired by nature.” The implications of biomimicry for the field of architecture could alter the way we design, the materials we choose, and ultimately even the forms of our buildings.

HOK / Vanderweil's retrofit of a government building takes the notion of incorporating nature into design to a whole new level. The facade uses algae-housing tubes to serve multiple functions, including using algae as a fuel source.

When building green, it’s easiest to start from scratch, but the blank slate is an ideal rather than a reality: our stock of existing buildings necessitates energy-efficiency retrofits.

The new Barclays Center will not only provide a home for the Brooklyn Nets but will offer the surrounding community a civic space and an architectural  icon.

Not since 1957, when the Dodgers left Brooklyn for Los Angeles, has this popular New York borough been so close to finally having a major league sports team to call its own. Despite significant public opposition, a faltering national economy, a Supreme Court case over eminent domain, and a Frank Gehry design deemed too expensive, the Barclays Center is well underway, with construction due to be completed in September 2012. Designed by SHoP Architects and the sport facility practice at Ellerbe Becket, this voluptuous mass with weathered steel skin will be the $4.9 billion home of the Brooklyn Nets NBA team.

After centuries of consideration, a bridge to connect Sicily and the Italian peninsula is scheduled to begin construction in December.

For hundreds of years residents of mainland Italy and the island of Sicily have discussed the idea of a bridge that would connect the two bodies of land by spanning the Strait of Messina. However, because of the two-mile width of the strait, its depth, its current, and the fact that it frequently experiences tremors and earthquakes, a bridge seemed to be out of the question. Because of these issues, a ferry system was developed and used instead. Still, the idea of a bridge that could support both cars and trains seemed ideal for commuters.

This renovation of a market in Spain preserved more than just a historic building. Restoring the Santa Caterina Market's prominence as a commercial venue has helped to preserve a traditional way of life.

Very few countries are better than Spain at taking the old and transforming it into the new. Currently, this trend has found a new focus – the neighborhood market. Before the chain supermarkets or giant shopping centers began to eat up every available space in town, every neighborhood had its local market. These old (and usually somewhat decrepit) markets have suffered years of neglect and seen hard economic times for private vendors. Now these almost abandoned markets are ripe for the picking, and architects and designers alike are vying for a chance to get their hands on the vast open space that is typical of these buildings.

Zaha Hadid’s building at the London 2012 Olympic Park is more than simply an aquatic center: it will factor largely into the public experience of the Olympic Games.

For the gateway to London’s Olympic Park, internationally acclaimed architect Zaha Hadid was selected to design one of her signature sculptural buildings. Hadid's London Aquatics Centre will be the venue for Swimming, Diving, Synchronized Swimming, Paralympic Swimming, and the aquatic portion of the Modern Pentathlon. It is scheduled to host 192 events in all.

The Florida Southern College campus offers the world’s largest collection of Frank Lloyd Wright buildings on a single site. The 10 interconnected structures offer an unparalleled view of how Wright intended buildings to be part of a larger, organic whole.

"Out of the ground, and into the light, a Child of the Sun": Wright’s simple but powerful statement describing Florida Southern College offers us a glimpse into the mind of America’s most influential, iconic, and (yes) poetic architect. It also informs us of the organic nature of his architectural thought and practice and is a signpost of his philosophy. Simultaneously, it gives us something of a prophecy regarding the possibilities of biophilic design. Wright championed his own philosophy of organic architecture and, while not 100% compatible with today’s ideas of biophilic design, it certainly laid a strong foundation of intellectual and philosophical support for the movement. Wright’s statement also conjures up images of the profound relationship his buildings displayed with regard to Nature (that’s Nature with a capital N, as he was fond of saying). It is worth noting here that his words could have easily come from one of his creative heroes, such as Ralph Waldo Emerson, Henry Thoreau, or Walt Whitman, all of whom had a galvanizing effect on Wright’s thinking and his philosophy of how nature and architecture can be part of an organic whole.

What is it that makes a person like a building? Beyond simple differences in individual taste, scientists are identifying biologically based responses that determine our preferences.

Green design can mean many things. Even the most structured green building rating systems reflect this fact. At their most encompassing, rating systems can include far reaching social and cultural goals; at their most pragmatic, these systems still emphasize the importance of environmental quality for the end user. However, this type of imprecise consideration is often overshadowed by components that are more measurable, such as energy-efficient heating and cooling systems or water usage.
