Eighty-one years ago this May, traffic opened on a newly constructed bridge span between Marin County, California, and the city of San Francisco. At 4,200 feet long and with towers 746 feet high, the steel suspension bridge was the longest and tallest bridge of its time. Built at a cost of $35 million, held together with 1.2 million rivets, and painted international orange from end to end, the Golden Gate Bridge was an instant symbol not just of California idealism, but of American engineering and construction might.
While the Golden Gate is no longer the longest or tallest bridge in the world, its iconic status has endured. Named one of the seven wonders of the modern world by the American Society of Civil Engineers, the Golden Gate enjoys regular special attention from 13 ironworkers and 28 painters who replace corroding steel and rivets with high-strength steel bolts and constantly touch up the span with paint to prevent corrosion.

Whether you call it 3D printing, additive manufacturing or contour crafting, the ability to create something — from a small tabletop model to a livable home or towering skyscraper, to list just a few possibilities — out of paper-thin materials is intriguing, and promises to shape the future of our world. So promising is this recent technology, in fact, that manufacturing industries, government entities and educational institutions have made significant investments in 3D-printing technologies. These ventures, particularly those driven by partnerships, are shaping up to have a big impact on the building and construction industry.

Disaster strikes. It’s inevitable, given enough time. Regardless of where you live, there are natural disasters waiting to happen, be they earthquakes, floods, tornadoes or hurricanes. Meteorologists and emergency service providers can often provide advance notice of weather-related disasters like hurricanes, but seismic events, tornadoes and flash floods can often occur with little or no warning.
In the wake of recent catastrophic events such as Superstorm Sandy (233 deaths, $75 billion in damages), the 2011 Joplin tornado (158 deaths, $2.8 billion in damages), and Hurricane Katrina (1,245 deaths, $108 billion in damages), emergency management experts are increasingly evaluating the benefits of sheltering in place as opposed to evacuation. According to the Federal Emergency Management Agency (FEMA), sheltering in place is generally advisable when it may be dangerous to leave your home or place of employment.

It was a muggy Tuesday morning, and thousands of people from all over the world were heading toward the long bank of doors to the Orlando Convention Center. The broad stream of people was just one of the signs that the International Builders’ Show® was underway.
Inside Hall C The Simpson Strong-Tie booth was impressive with a festively lit Outdoor Accents® pergola and shelves of Simpson hats and tee-shirts to give to booth visitors.

Simpson Strong-Tie is renewing its partnership with Habitat for Humanity to continue supporting the housing organization’s efforts to make homes resilient to disasters. This is the 12th consecutive year of the partnership to help more families in need of a decent and affordable place to call home. To date, the manufacturer of structural product solutions has contributed more than $2.75 million toward Habitat’s mission.

After the collapse of the housing market in 2008, homebuilding is back on the rise, and the cost of housing is increasing nationwide.
According to the United States Census Bureau, in the third quarter of 2017, the median asking price across the country for a vacant rental unit reached an all-time high of $912. In comparison, the median rental price for vacant units in 1997 was below $500 nationwide. That kind of an increase outpaces inflation, adding significant burden to the wallets of renters nationwide. What’s more, the Joint Center for Housing Studies of Harvard University (JCHS) reports that nearly 48% of renters in 2015 spent more than 30% of their income on housing, with lower-income homes being the most affected.

Good news for anyone involved in construction: The industry added 23,000 specialty trade contractor jobs in November 2017, according to the U.S. Bureau of Labor Statistics. The bad news? Construction employers will likely struggle to fill new positions, as a labor shortage triggered by the 2007–2009 Great Recession continues to dampen more robust growth for the builder economy.
In fact, the number of builders reporting a critical shortage of labor has grown from 21% in 2012 to 46% in 2014, 52% in 2015 and 56% in 2016, says Paul Emrath, who tracks industry economic statistics as the vice president for survey and housing policy research for the National Association of Home Builders.

Modular construction — sometimes also known as prefabricated, prefab, prebuilt, manufactured, factory-built, or panelized construction — ain’t no stroll in the trailer park. Although double-wides and modular prefabs sometimes roll off the same factory floor, the similarities end there between mobile homes and true modular construction, which is gaining a foothold in markets as builders and developers look for higher-quality, more efficient construction processes.
Like component construction, modular building takes much of the labor off of the construction site and puts it on a factory floor, where assembly can be value-engineered to minimize waste and maximize speed and overall product quality. And while modular building includes trusses and panels, modular component facilities are much more than your run-of-the-mill truss plant.

Of all the possible mistakes that pop up across East Coast construction sites, one easy-to-correct framing blunder continues to vex even the best builders and structural engineering experts – the use of incorrect fasteners. Despite the industry’s best training efforts, the availability of print handbooks and installation guides, and even easy-to-understand smartphone videos and graphics, framing laborers are seemingly content to bang away at various anchors, straps and plates using whatever nail happens to be loaded in the gun.
“Even with great advancements in building designs and roof and framing systems, the bigger issue remains how well those designs are executed in the field,” explains Simpson Strong-Tie builder service rep Kevin Kelly. “No matter how much training we do and how many pocket install guides we publish, the biggest issue with framing connectors is always the use of incorrect fasteners.”

The more things change, the more they stay the same. Take framing, for instance. In November 2009, Simpson Strong-Tie Pacific Northwest Outreach Coordinator Jim Mattison penned the article Framing Hardware Dos and Don’ts for the Journal of Light Construction, outlining some of the most common framing errors as seen in the field, including notching studs and joists around anchors, using incorrect fasteners and overdriving nails with pneumatic nailing equipment.
So what’s evolved out there on the jobsite in the eight years since? “Not much,” bemoans Mattison, who says common framing mistakes still vex most of the builders he visits across the Western US. “When it comes to installing the hardware, the problems that plagued the industry in 2009 persist today, and while some of the hardware has changed in configuration and use, simple installation errors regarding use of incorrect fasteners and fastener overdrive are still happening frequently.”
