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.

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.

When you live in earthquake country, you know it’s not “if” there will be a big quake, it’s “when.” You may have an earthquake emergency kit ready, but there are also steps you can take now to strengthen your home to make it more resistant to earthquake damage. And if you live in California, there’s a program called the Earthquake Brace + Bolt (EBB) that provides up to $3,000 for seismic retrofit grants to homeowners residing in more than 150 California zip codes. If you’ve checked it before and your zip code wasn’t listed, be sure to check it again because the list has been expanded.

From hurricanes and earthquakes to wildfires, floods, freezes, droughts, severe storms and more, natural disasters plagued the United States in 2017. The National Centers for Environmental Information (NCEI) reports that 2017 could be a record-breaking year for disasters that cause over $1 billion in damage. As of October of 2017, NCEI reported 15 such events in the United States, only one fewer than in the record year of 2011. Without going into the details of why these events occur — we’ll leave that to the scientific community — there are ways to prevent damage and destruction by building resilient communities and structures.

Warm winter wishes for a joyful holiday season and a happy new year!
On a Sunday morning in late August 2014, a 6.0 magnitude earthquake surprised Napa, California residents and caused structural damage to many homes and businesses in the area. One of the most powerful earthquakes in Napa’s history, local news outlet KQED reported $300 million in damage to homes and commercial properties.
Napa is right in our backyard, about 60 miles north of Pleasanton. Many Simpson Strong-Tie employees felt the quake, but fortunately no one was injured. If you’ve ever been in a large earthquake, you would probably agree that it’s a frightening and unsettling experience. And unlike other natural disasters, there’s no warning. Here is one woman’s story about the Napa earthquake:

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.

There are a couple of turkeys that like to hang out around our home office in Pleasanton and, no, I’m not referring to any of my colleagues — we actually have a gang of wild turkeys that comes up from the creek behind the office. Almost every day, these colorful birds feel safe enough to stroll onto the office walkway pecking for food outside our office windows and doors. It’s surprising to me that these beautiful creatures could be so fearless (or is it simply naïve?), especially around Thanksgiving time. Their presence reminds me that being fearless is important, because nothing new would ever be discovered if we were too afraid to venture outside our comfort zones.

If an earthquake were to strike at this very moment, are you confident your home is adequately constructed to withstand it? Depending on where you live, how your house is built—and the year in which it was originally constructed—an earthquake could have a devastating impact on your physical and financial health.
We’ve all witnessed the catastrophic impact that large earthquakes can have on society recently, and our hearts go out to those affected in Mexico who are picking up the pieces. Since October is Earthquake Preparedness Month and October 19 is the Great ShakeOut earthquake drill, we thought we’d share some steps homeowners and building owners can take to help minimize the risk of damage.

There’s been a lot of discussion recently about resilient buildings and resilient communities, including what it means to be resilient, why it’s important, whether it’s possible within budget constraints, and how it can be achieved. The 100 Resilient Cities Rockefeller Foundation initiative defines “urban resilience” as “the capacity of individuals, communities, institutions, businesses, and systems within a city to survive, adapt, and grow no matter what kinds of chronic stresses and acute shocks they experience.”
The discussions have noted that communities are made up of several components that are necessary to consider when developing a plan for resilience — such as buildings, infrastructure, water, power and communication. Even though community resilience is multi-faceted, the resiliency of buildings is a crucial component because research shows that Americans spend 90% of their day inside buildings.
