At this time we will continue normal business hours.
As the Golden Gate Bridge was being built, Joseph Strauss, the chief engineer, was often asked: How long will the bridge last? His answer was always the same.
“Forever,” he said.
The famous span turns 80 on Saturday, not quite forever, but nearly a lifetime. And how long the bridge lasts depends on a small army of painters, ironworkers, electricians and engineers whose job over the years has taken them to the top and the bottom of the towers and everywhere else on the bridge.
Currently, the Golden Gate Bridge employs 32 painters, five painter laborers, 19 ironworkers, and three ironworker foremen, called “pushers” in the trade. A superintendent is in overall charge.
Though the painters are the most visible of the maintenance crew, it’s the ironworkers, who walk the high steel and build the scaffolding for the painters, who capture the public imagination.
“We have a nickname. They call us Sky Cowboys,” said Phillip Chaney, 57, the ironworker superintendent.
Their job is to replace rusting rivets with bolts, to build scaffolding for the painters and to make sure the bridge is sound.
“The paint protects the steel, but it’s the steel that holds up the bridge,” Chaney said.
“We have a corner office with a view,” said Darren McVeigh, 51, a second-generation ironworker who has been with the Golden Gate Bridge for 15 years and in the trade since 1982.
It’s “rough and dirty work,” McVeigh said, but it’s a good job.
Ironworkers report at 6:30 in the morning and are off by 3. It’s a union job, and the pay is good: $41.53 an hour, according to bridge district figures. It takes a four-year apprenticeship to become a journeyman, and Golden Gate work is especially prized in the trade: Bridge workers get 13 paid holidays, plus vacation.
In other jobs, McVeigh said, “When you don’t work, you don’t get paid.”
On the other hand, working on the Golden Gate presents special problems. The bridge crosses a strait on the edge of the Pacific Ocean, and the strait is famous for its wind and fog.
“Sometimes it cuts through you like a knife,” McVeigh said. “It’s brutal, just brutal. At the end of the day, all you can do is stand under a hot shower.”
The moisture from the fog and rain also add an element of danger to the work because it makes the steel slippery.
No one can be an ironworker who has a fear of heights, but the trade requires a finely honed sense of caution.
“You know the saying: ‘One hand for the company and one hand for yourself,’” McVeigh said.
All ironworkers on the bridge are required to wear a harness — 100 percent tie-off they call it — but there’s a trade-off. With layers of clothing on a chilly day, a body harness and a tool belt, ironworkers look like bears up on the steel. It makes it harder to move, to work.
Though 11 workers were killed during construction, there have been only two fatal accidents involving bridge crews in the past 80 years. In 1970, a painter fell to his death, and in 2003 an ironworker in the employ of a contractor died in an accident during a seismic retrofit project.
And there are also injuries, especially working with steel beams and building scaffolding.
“You get hand smashes and eye injuries, back injuries, bad knees,” McVeigh said.
They also face death, especially when someone is threatening suicide. Bridge workers are trained to intervene and will go to the railing to try to stop someone from jumping. “We put on a harness and tie-off so if they go, we are not going to go with them,” McVeigh said.
Like the others, he has talked some would-be jumpers off the edge. “I’ve lost count,” he said. “Maybe a dozen.”
In the next few years, a suicide barrier will be strung under the deck. The work won’t be done by in-house ironworkers, but by ironworkers hired by the contractors for the job.
The ironworkers’ main work at the bridge is keeping it standing. “There’s an old saying,” McVeigh said. “Rust never rests.”
Chaney points to a long color-coded chart in an engineering office near the toll plaza. It’s a conceptual printout of the bridge, showing the results of regular inspections: green for good steel, yellow for caution, red for problems.
Last year, the ironworkers spent a lot of time replacing some of the 600,000 rivets in the Marin tower. Rusted rivets are removed by a device called a “rivet buster” and are replaced with steel bolts.
Most of this year is devoted to building stages — “dance floors,” they are called — under the roadway deck, so old paint and some steel can be replaced. The stages are surrounded by tent-like structures that keep the old paint and debris from falling into the water.
It takes months to build the stages and the tenting, careful work done under the roadway. It’s not as dramatic as high work on the 746-foot-tall towers, but just as important.
There are other jobs, too. “I have guys working on greasing the bearings on the deck,” Chaney said. Like all suspension spans, the Golden Gate Bridge moves with the weight of traffic and with the wind. The steel moves. “You don’t want a stiff structure,” he said.
After the stages are done, the next big job will be to work on the San Francisco tower, where the effects of wind and rain have left the tower looking a bit shabby, as if it needs a new paint job. “It’s structurally sound,” Chaney said, “but not aesthetically.”
Not everybody can work on what may well be the most famous bridge in the world. Like others on the bridge, McVeigh is proud of it.
“When you are driving to work and see it in the windshield,” he said, “you say to yourself: ‘Wow! Look at this thing!’”
A quiet anniversary
It will be a quiet birthday Saturday when the Golden Gate Bridge turns 80.
Instead, the Golden Gate Bridge, Highway and Transportation District is inviting the public to post personal stories about the bridge on the bridge’s Facebook page and to Twitter @goldengatebridge, hashtag #GGB80 and #MyGGBstory.
The idea, the district says, is to “allow visitors from all over the world to join the fun.”
On the bridge’s 50th anniversary, in 1987, as many as 300,000 people walked on the bridge, causing the arch in the main span to flatten. The bridge staged an elaborate fireworks display on its 75th, in 2012. See Original Article >
When companies in industries from agriculture to shipping need standard fasteners, they have plenty of options for purchasing them. But when a special part is needed, only a company that focuses on delivering custom fasteners will ensure a quick turnaround and superior product. At Chicago Nut & Bolt, custom work is what we do, and our custom fasteners can be made to any specifications in a timely manner that has impressed our clients for 20 years.
Despite the complex parts we have been able to produce during the past two decades, our process is simple. It begins when a client sends a blueprint for a part, which might be anything from a custom screw for a century-old bridge to a 6-ft. bolt for a crane. Based on the blueprint and specifications for features like a particular grade of steel or type of plating, we typically provide a quote within 24 hours. That’s our goal, and it’s an industry-leading turnaround.
Once we send the quote and it becomes an order, we coordinate with the manufacturers handling the multiple aspects of production that go into developing a custom order. Next, we continue to the vital step of quality control. During this testing phase, our experts check 30, 60 or even more dimensions, verifying them within a tolerance range. Only after all quality measures have been approved do we package the order. Along with the parts, we send certification that all material grade and strength properties have been met. Everything needed is shipped to the customer, but we also offer warehousing. That means, our customers have the option of making large orders and asking for their certified parts as needed.
There is a lot that goes into making custom fasteners, but because we have been doing precisely that for 20 years, we have a tested, step-by-step process that enables us to offer the quickest turnaround in the market.
Crafting just the right piece of hardware can sometimes feel like creating a piece of jewelry. And when custom bolts and nuts are needed to secure heavy equipment, absolute precision is necessary. A recent custom fastener we developed for hydraulic mining equipment both met the exacting tolerances of the blueprint and sparkled like a golden pendant thanks to its distinctive plating.
The client came to Chicago Nut & Bolt with an order to produce 2,500 custom pieces with several special features. First, the fastener had to be crafted from high-alloy hardened steel, which would provide considerable strength and resistance to corrosion. Because the mining equipment would be exposed to wet conditions, including ocean water, this high level of preservation was key. Second, the custom fasteners needed to feature internal and external threads so that they could be screwed both inside and out. Basically, it was a special nut and bolt combined in one piece.
Based on the client’s exacting blueprints, we began the process of filling this custom order by utilizing CNC machinery. Thanks to this advanced technology, the raw steel could be cut in a precise manner with a computer-controlled metal lathe. The CNC machine also added the interior and exterior threads to this special fastener. Next, the pieces were heat treated and finally plated, which created the gold sheen that makes the fasteners look like a modern piece of industrial-style jewelry. At each step in the process, our team performed a stringent quality inspection.
Finally, the 2,500 special fasteners were packaged to the customer’s specs and shipped. From blueprint to delivery, the process took about four weeks, although we have been known to create custom nuts and bolts as fast as overnight or within a few hours. That’s because our main capability is creating one-of-a-kind nuts and bolts in quantities from one to 1 million. Not every custom fastener we manufacture will look like a piece of jewelry, but every piece will always be just the right fit.
Chicago Nut & Bolt manufacturers custom large size fasteners, including bolts, nuts and screws per blue print. With over 20 years in the custom fastener business, Chicago Nut & Bolt supplies quantities from one to 1 million pieces and can also warehouse orders.
Business Insider has broadcasted a video showing just how radically a high-speed train would revolutionize our traveling systems. Hyperloop is in the making and has some great projects ahead to making this high-speed train a reality.
According to this video, the US railroad network is composed of about 140,000 miles of tracks. Many passengers travel by train at only 50 mph. The top speed of the fastest train, AMTRACK, is on average anywhere between 80-90 MPH.
A new vision for high-speed trains would connect to all the U.S major cities of a 170,000 mile network. Here is how it would be mapped out.
For many Americans, travel is a huge part of their summer plans. Spending the season on the open waters, cruising while enjoying the weather and scenery, is a favorite pastime. And while boarding these vessels and perfecting their tan, most people aren’t thinking about the components that go into shipbuilding. The same is true for the trains that bring countless American families to their destinations throughout the season.
For the ship and railroad builders, however, every component is critical, and of utmost priority is safety. Take fasteners, for instance. They’re small but crucial parts of these large modes of transportation, and safely getting from point A to point B depends on their quality.
Did you know that forensics have concluded that it might have been faulty fasteners that ultimately sunk the Titanic? While a lot of time has passed since that fateful voyage, what hasn’t changed is the importance of fasteners, and the need for quality construction and design.
At Chicago Nut & Bolt, we manufacture custom fasteners—inclusive of custom nuts, bolts, and screws—for a wide variety of industries and applications, including the ships and trains that bring people to and from their summer vacations.
We meet all specific requirements and sizes and make blanks in every imaginable head style—all the while making quality our number one priority.
As an ISO-certified, Fastener Quality Act-compliant company, using the most sophisticated testing and certification procedures, safety is always ensured, and the quality is always uncompromised.
The last thing travelers should have to worry about is the safety of their transportation; when companies choose to use our fasteners, it’s something no one has to worry about.
2015 is all set to be a landmark year in the history of US manufacturing. The trend of sustainable growth as shown by 2014 is a presage of a potential boom in the sector. A long-awaited positive turn after the recent economic slump of the recession!
As per the discussions and opinions of leading analysts, 2015 will set the course for the engine of manufacturing to traverse. The Boston Consulting Group’s analysis has revealed the fact that the default choice of offshoring – China will no longer be able to hold on to its favored position. The mandate to provide minimum wage increases of 15 to 20 percentage points every year has reduced the cost benefit of manufacturing in China to 55% in 2014 and will further push it down to a dismal 39% in 2015. It is not hard to envision the disappearing allure of opening manufacturing units on foreign soil for every conceivable product irrespective of the demand in these offshore markets.
However, labor is not the only cost associated with manufacturing. Transportation, the cost of raw materials and obviously the cost of electric power all contribute heavily to determining the location of the factory. According to the US Energy Information Administration, crude oil production is all geared to touch a record high of 9.3 million b/d in 2015. Thus, the dwindling advantage of cheap labor can no longer offset the high cost of transportation across the seas. Under such circumstances, the abundance of fuel within the country is bound to sway decisions in favor of re-shoring.
Alternative energy production is also becoming more affordable and reliable. By 2040 15% of the global energy consumption will be attributed to alternatives and the US is right at the forefront of this trend promising inexpensive and readily available electricity to power manufacturing ventures.
The Markit Manufacturing Purchasing Managers’ Index (PMI) is also optimistic. It is sitting steady at 54.8 at the end of November, and this indicates a rise in the volume of bulk orders and sales to foreign markets.
The US manufacturing sector has always been the main impetus behind the growth of the nation. It drives two-thirds of all R&D efforts, and its workers are twice as productive as others enjoying higher wages and a better lifestyle. (*National Association of Manufacturers)
Considering major indicators – 2015 is shaping up to be the time to celebrate the return to glory of US manufacturing and will herald prosperity if all external factors co-operate.
It’s that time of the season when the work comes to almost a stand still. Yes, it is the holiday season, and it is the best of the times, as well as the worst of the times for the retailers and manufacturers. It is the best time because everyone is busy, and the economy is good, but on the downside the capacity to meet the demands becomes tight. This is because of the congestion in the ports at Long Beach and Seattle, and due to this congestion, the containers are stuck in the port for weeks. This results in the disruption of the supply chain and hence the retailers and manufacturers are unable to meet the demands. This is where Chicago Nut and Bolt plays the role. We help people get out of trouble. Our reputation is built on flexible and attentive fastener supply services rendered to meet the needs of customers all over the world.
At Chicago Nut and Bolt we undertake delivery of emergency orders for custom fasteners, custom bolts, custom nuts, and custom screws quickly, in compliance with all specifications. Despite the standard delivery time of one week, we can accommodate emergency custom orders overnight or within a few hours. As soon as the request is received by the CNB representative or engineer through fax or email, the pricing as well as delivery information is sent to the customer within minutes. The order is then sent to the customer and is tracked right from the production to packaging to final shipment.
We know that finding a manufacturer to produce a custom part is hard, but we can produce the part and deliver it when you need it. Though we carry standard fasteners all the time as a custom fastener manufacturer, we focus on producing the right part to meet the requirements of our customers.
