The good news is commercial construction is picking up after several dismal years, with construction spending projected to be 5.5 percent higher in 2014 than 2013. The bad news is the Associated General Contractors of America (AGC) has pointed out “a skilled labor shortage in the country may threaten projected growth and the ongoing recovery.” How can structural insulated panels (SIPs) help?

Designing proper construction details is an important part of architecture and engineering practice that involves more than just a grasp of building technology. If designers are not also alert to market conditions, then their details—no matter how elegant—can be ineffective and hinder the pace of a project. Overlooking the complications surrounding the specification of adhesive anchors is a prime example, as recent code changes regarding their use threaten to stall building projects in some of the United States’ largest jurisdictions.

Today’s coatings are more specialized than ever, meeting the demands of various applications. It can be difficult to navigate product options, keeping in mind performance, substrate, volatile organic compound (VOC) regulations, green certifications, sustainability, and aesthetics. With so many different aspects coming into play, the process is complex.

Fire-rated curtain walls can prevent a fire from traveling to or from neighboring buildings without restricting visibility. Unlike gypsum, masonry, and other opaque fire-rated materials, this multi-functionality can bring fire and life safety goals in line with the aesthetic design intent where building codes deem the threat of fire is significant from adjacent construction.

Glazed curtain walls are best known for their ability to visually integrate two otherwise separate spaces. Less talked about—though, perhaps more important—are curtain walls with the capability to retain visibility and access to daylight while standing guard against fire.

By Tom Savoy
The Chicago Park District will soon open a new 11-ha (28-acre) downtown park to complement its renowned Grant Park and Millennium Park. Visitors to Maggie Daley Park will enjoy a visually varied landscape with rolling hills, berms, and contours. What they might not realize is the park’s earthworks are not made of traditional soil fills, but of a geosynthetic material—expanded polystyrene (EPS) geofoam.
