Top 10 Structural Steel Marvels Around the World

,

October was last month, and the construction sector had a lot to celebrate with SteelDays (October 17–20) and World Architecture Day (October 2)! To commemorate the hard working people in the steel industry and the incredible structures they create, here is a list of the top 10 structural steel marvels around the world (in no particular order).

1. Burj Khalifa (Dubai, U.A.E)

Towering over the city of Dubai at 2,722 feet, the Burj Khalifa is by far the world’s tallest building. Builders used 31,400 metric tons of steel rebar to construct this skyscraper. Laid end to end, this amount of steel would be equivalent to one-quarter of the earth’s circumference.

The colossal tower has 163 floors, which include restaurants, apartments, and business suites. The building also boasts the tallest elevator shaft in the world, which is open to the public if you’re brave enough to ride to the top.

2. Empire State Building (New York, U.S.A)

Despite being surpassed in height by many other towers, the Empire State Building remains an internationally recognized landmark. Completed in 1931, during the height of the Great Depression, the Empire State Building remained the tallest building in the world for 41 years.

The building’s design changed 16 times during the planning and construction process, but thousands of workers constructed the building in a record one year and 45 days, using 60,000 tons of steel. This distinct skyscraper all but defines the famous New York City skyline.

3. Space Needle (Seattle, U.S.A)

This fun futuristic building in Seattle includes a disc-shaped observation deck that resembles an extraterrestrial ship. Built in 1962 for the World’s Fair and in celebration of the “Space Age”, the Space Needle’s tower measures 605 feet tall, and the saucer observation deck measures 130 feet in diameter.

It is one of the most photographed structures in the world and offers Seattle visitors a 360-degree panoramic view of the city and surrounding Olympic Mountains.

4. Petronas Twin Towers (Kuala Lumpur, Malaysia)

These iconic steel structures are the tallest twin towers in the world. Measuring at 1,483 feet, the Petronas Twin Towers are connected by a bridge on the 41st floor and feature incredible views of the city.

While the towers are primarily made of concrete, the glass and stainless steel exteriors are arranged in a traditionally Islamic eight-pointed design, which has solidified the structure’s reputation as an iconic Malaysian monument.

5. Brooklyn Bridge (New York, U.S.A)

Located in New York City, connecting Brooklyn and Manhattan, the Brooklyn Bridge deserves a place among the top 10 as it was the very first steel-wire suspension bridge built in 1869.

The steel was so thick and the construction so challenging that it actually took a decade to complete. This bridge is one of the most recognizable bridges in the country and has become synonymous with its city of origin.

6. The Sydney Harbor Bridge (Sydney, Australia)

In addition to the Sydney Opera House, the Sydney Harbor Bridge all but defines this Australian city. The Sydney Harbor Bridge is the largest steel arch bridge in the world, measuring 440 feet in height and 1,650 feet in length. The bridge officially opened in 1932 and features four railroad tracks, a highway, and two pedestrian walkways.

7. The Chrysler Building (New York, U.S.A)

New York City is simply full of structural steel icons! In addition to the Brooklyn Bridge and the Empire State Building, the Chrysler Building is a legendary landmark in the New York City skyline.

Measuring 1,046 feet, the Chrysler Building was the tallest building in the world in 1929; but the title was shortheld, as it was surpassed by the Empire State Building in 1931. While this building is not made entirely of steel, the iconic steel framework defines this structure and is easily recognizable as a staple of New York City architecture.

8. Sears Tower (Chicago, U.S.A)

The Willis Tower (formerly and commonly known as the Sears Tower) was built in Chicago for the Sears Roebuck and Company. During the height of its sales as the world’s largest retailer, Sears decided to build 3 million square feet of office space to accommodate its 13,000 employees.

The 1,454-foot-tall steel building attracts over a million tourists each year and has the world’s highest occupiable floor as well as the highest roof deck; in fact, you can see four states from the deck.

9. The Gateway Arch (St. Louis, U.S.A)

The tallest arch in the world, the Gateway Arch, sits on the west bank of the Mississippi River and reflects St. Louis’ role in the Westward Expansion of the United States during the 19th century.

Measuring at 630 feet in both height and width, this unique experience features two trams where visitors can take a short tram ride to the overlook at the top of the arch. The Museum of Westward Expansion is at the base of the arch and shows what life was like during the 1800s.

10. Beijing National Stadium (Beijing, China)

The Beijing National Stadium, also known as the Bird’s Nest, is the world’s largest steel structure. The design, which drew inspiration from traditional Chinese ceramics, had to be both impressive and useful in order to withstand Beijing’s earthquake-prone activity. Over 100,000 tons of steel were used to create this stadium, which now holds a capacity of 91,000 and can withstand a seismic magnitude of 8.

Exploring the Exposed Steel at Globe Life Field

,
alt=""

The new home of the Texas Rangers, Globe Life Field, is an architectural masterpiece. Since its opening in 2020, the field has become an icon of downtown Arlington. Given the size, scope, and vision of the entire project, it is no surprise that exposed steel was its chosen material.

Globe Life Field’s Architectural Magnificence

Construction for Globe Life Field began in 2017 and took 38 months to complete. Manhattan Construction Company served as a general contractor for the massive project which incorporates 34,000 tons of steel. 15,000 tons of steel were utilized below the roof and 19,000 tons were devoted to the stadium’s state-of-the-art retractable roof.

 In fact, this retractable roof is the largest of its kind and consists of two rail truss structures; the movable portion and the two fixed roofs.

The construction of the roof used various construction methods. Such as the ground-built 600-ton roof trusses hoisted into place using a 2,535-ton-capacity Manitowoc 31000— the largest crawler crane ever built in the United States. 

In addition, W&W Steel Erectors (WWSE) designed, fabricated, and installed temporary shoring towers, allowing for the long-span trusses and the entire roof to be built from the inside of the field.

Engineered with a Vision

The Texas Rangers pictured a field where fans were as close as possible, and architect HKS designed multiple seating options. All with unobstructed views of the field comprised of seven tiers vertically stacked and leading to seven unique front-row experiences.

“It’s all about intimacy and making the spectators part of the game,” said Greg Whittemore, principal at HKS.

Due to facing the challenge of supporting multiple elevated seating decks and suites above the lower bowl, the engineering group, Walter P Moore had to employ multi-story cantilevered steel trusses concealed within each suite divider. In doing so, it eliminated the need for columns as well as any chance of an obstructed view.

Steel’s Use in the Field

The flexibility of steel allowed for more than just concealing support beams, it also allowed for unique asymmetric steel Y-columns in order to make up for insufficient space. The initial concept envisioned connecting two adjacent suites. However, this would have been at the expense of disrupting the flow of the crowd between the suites.

Shruti Sharma, principal at Walter P Moore, explained that traditional straight columns would have punched right through the lower seating, leaving some seats unusable. By angling the support behind the lower bowl seating, the columns support the party suites from below. This ensures connectivity in the party suites and uses all seats in the lower bowl.

The exposed steel throughout the stadium is practical, but it also creates an incredible view. Walter P Moore and HKS intended for a steel support element for the east box truss at the south side of the venue. In doing so, it creates a signature sloping steel truss column that slices through the seating bowl, creating a dramatic structural feature.

The practicality of this amazing view helps reduce the span of the fixed roof truss to 520 ft from 650 ft.

The Need for Exposed Steel

Walter P Moore credits the flexibility of steel with making all of this possible. The strength, durability, and ductility of steel also give it a unique aesthetic, unlike any other modern ballpark. The exposed structural steel creates an impression that emulates historic ballparks from the past.

Flexibility and durability aren’t the only things that make steel so great for construction. Its lightweight nature makes it a versatile tool for various projects and its sustainable properties save companies thousands.

The Power of Steel at U.S. Bridge

The flexibility of steel proved itself throughout the construction of the ballpark, and in many more projects. As an AISC certified steel fabricator, we are proud to manufacture and build with steel as our primary medium. All of our bridges are manufactured with high-quality, long-lasting materials that are available in a variety of design and support types.

Recycled Steel in Construction

,

Steel is one of the most popular construction materials available. It’s non-flammable and a better choice in areas that might be prone to earthquakes or other natural disasters as it is less likely to warp. It is also stable enough to sustain high winds, which makes it a great option for areas that are often affected by hurricanes.

In fact, it is one of the most durable construction materials available. But its strength and long life span isn’t the only important thing about steel. Its sustainable features make recycled steel one of the best materials available for construction projects.

How it Works

One of steel’s best features is that it can be recycled. In fact, over 90% of a steel building or fixture can be recycled and reused for another project. This is a far higher recycling rate than other common building materials, like concrete or wood. As a result, the steel industry has reduced greenhouse gas emissions by an estimated 36% in the past 30 years.

Recycling steel is fairly easy. The steel is magnetically separated from other materials and then shipped to steel mills or other factors for recycling. It is then melted down and recreated into the manufacturer’s desired molds. In 2019, recycled steel accounted for about 600 million tons of all steel produced.

The primary issue when recycling steel is identifying and separating different steel grades from one another during demolition. According to the Institute of Scrap Recycling Industries, there are 316 different grades of steel.

Why Recycled Steel

The majority of construction demolition are heavy bulk wastes like concrete which are generally downcycled into general fill. However, many companies are seeing the benefits of using sustainable materials like steel instead of or in pair with concrete.

Nowadays, ninety-three percent of all steel used in construction projects is recycled. Why? Because it poses many benefits for companies as well as the environment including reducing waste by diverting it from landfills and back into other projects.

  • It reduces waste and is eco-friendly. One major benefit of reusing steel from buildings and structures is that beams, columns, and other structural pieces can be used without having to be re-melted or processed. Scrap pieces of steel, on the other hand, can be melted down and made into something new. In fact, 98 percent of a building’s steel is recycled back into other steel projects after the building’s life-cycle ends.
  • It retains its quality. Steel’s quality is not compromised, even after it’s recycled. Reusing steel doesn’t degrade the products’ strength or value and it has a great weight capacity.
  • It saves money. While recycled steel is no different in quality than new steel, it is however cheaper. Its lightweight nature means less use of heavyweight equipment and lifts. Additionally, builders save money on maintenance and repair due to steel’s long life span and durability.

When construction projects have the chance to cost millions of dollars, saving on one of your primary building materials is a huge win. Plus, it conserves primary resources and raw materials by using recycled components.

U.S. Bridge & Recycled Steel

U.S. Bridge prides itself on building structures that last. Construction plays a major impact on a country’s environment including its carbon footprint. Steel is a great material to consider in any project.

What is Weathering Steel?

Weathering Steel

Perhaps you’re considering constructing a bridge and you’re coming across terms like weathering steel, galvanizing steel, or corten steel, but you aren’t entirely sure what it is. Here at U.S. Bridge, we’ve built vast arrays of bridges for different locations across the nation. So we’ve created a guide to help you decide if weathering steel is the right step for your building project. Learn all about weathering steel in this article.

What is Weathering Steel?

Many builders choose this material for its durable and ductile features. Weathering steel is a low-carbon metal that contains additional alloy elements, including nickel and copper, which provides the metal better strength and resilience to corrosion. In addition, it is more affordable than other substances such as galvanized steel. Of course, this material isn’t ideal for every project or location.

Weathering Steel

Things to consider for Weathering Steel

The Pros of Weathering

The most notable component of weathering steel is its ability to resist corrosion. For this reason, it is a popular choice for exposed steel bridges or buildings. Weathering steel undergoes a process known as useful corrosion. While rusting is a problematic and even dangerous occurrence with other steel structures, it actually protects the material from further deterioration. Rust will only form in the outer layer of the steel which will then turn into a protective barrier that aids the resistance of future corrosion.

Additionally, the material requires little maintenance which is not only beneficial for rural or limited access areas but it also saves money in the long run. In studies, weathering steel has lasted several decades with minimal maintenance. And since the repair tends to be less involved, these bridges cost less over their lifetime than those made with other materials.

As a bonus, these structures don’t need paint for either protection or aesthetic reasons. Many people find the rust patina of this material to be attractive on its own and it helps avoid Volatile Organic Compound (VOC) emissions from paint coatings.U.S. Bridge Cambridge

The Cons of Weathering

Although weathering steel may sound ideal, there are a few factors that should be considered before construction. Certain weather and climate conditions can lead to issues with durability and corrosive resistance. For example, weathering steel should not be built in a high-chlorine environment.

In addition, it functions best with alternative wet and dry condition cycles. If the environment is continuously wet or damp such as submerged in water or buried under soil then it impedes the steel’s ability to effectively resist corrosion.

While many appreciate the aesthetic of its natural rust-like patina, it also creates an opportunity of staining nearby structures; so it’s best to keep it away from concrete or other easily-blemished materials.

Pre-Engineered Building Solutions Set Construction Industry for Growth

With new bridges and infrastructure on the way, we expect 2020 to be a big year for the construction industry. In addition, laborers are working hard to improve projects by enhancing the design and building process. As of late, the pre-engineered building solution has had a great effect on the construction industry. For example, it is meeting the increasing demand for modern infrastructure. This involves innovative, cost-effective, and timely construction. Above all, it’s important for construction laborers to understand the difference between building solutions. This also includes planning, design, and, of course, construction. As a result, they can determine the best solution for their project.

Pre-Engineered Building

During the pre-engineered building process, construction materials and its components are manufactured at a factory, then assembled on site. Not only does this save time, but it also ensures a more successful project outcome. In addition, this type of building solution is progressively setting the construction industry for growth in 2020.

“The construction industry is projected to grow, as a result of increasing demand for pre-engineered building solutions that reduce construction time and cost.”

Andrew Heycott, CEO of Mabati Rolling Mills

Advantages

Different from conventional construction, pre-engineered building solutions still provide uniqueness and custom-built features. Often times, they are also less expensive. Significantly, there are numerous advantages that come with these building solutions.

  • Construction Time
  • Versatility
  • Design
  • Energy Efficiency

Construction Time

Every advantage of a pre-engineered building solution will involve saving time on construction. Similarly, the goal for most projects is to complete them on time or sooner. These types of buildings also include a wide range of structural and aesthetic equipment. This combined with the use of customized design software quickens the process of project completion. Furthermore, choosing the materials and design ahead of time allows the manufacturing and erection of a construction project to be done at a quicker pace.

Versatility

Notably, pre-engineered buildings are highly versatile. As mentioned above, the wide range of structural materials provides more options when it comes to design. In other words, pre-engineered buildings can cater specifically to customers or architects, allowing them to choose which option will fit their needs. This versatility allows for customization and increases functionality. Every construction project should involve a plan or guide to follow. So, the more options available, the more precise a structure can be. For example, project managers and laborers are able to choose the most suitable design option or size specification for materials.

Design

Before building and erection, workers must consider the design aspect of the structure. The design process involves many steps such as preliminary research, worksite analysis, concept design, etc. A complete vision for design leads to a smoother building process. Significantly, modern-day technology such as computer analysis and design programs help to facilitate the overall design process. Once laborers understand the design of a structure, they can proceed to gather materials and physically assemble the structure.

Energy Efficiency

Protecting the environment is important in the construction industry. In other words, how can we increase infrastructure while providing as little harm to the environment as possible. Significantly, pre-fabricated building solutions are also eco-friendly and energy-efficient. Necessary parts of a structure such as roofing, insulation, coatings, and panels can be built using energy-efficient materials such as:

  • Recycled steel
  • Plant-based polyurethane
  • Fiberglass
  • Insulating concrete

Recovering Materials from Construction and Demolition Projects

Recovering Materials From Construction And Demolition

The mission to enforce more eco-friendly solutions is paving the way in today’s workforce. In fact, construction companies are discovering new ways to implement this cause and illustrate safety and recovery in the industry. It requires construction laborers to be smart throughout all processes, starting with design and leading to demolition. When buildings are demolished, what most people see are bundles of rubble and debris gone to waste. However, smart contractors and business owners are beginning to see that recovering materials from construction and demolition projects has more benefits than it does drawbacks. Fortunately, construction companies are now able to recover useful materials that can be used for future projects.

Benefits of Recovering Materials

Contractors and business owners have been discovering reliable resources found in piles of demolition debris. These materials can be collected for future construction and renovation projects. Additionally, they have provided:

  • Environmental Benefits: Recovering materials from construction and demolition conserves landfill space and reduces greenhouse emissions. In fact, according to the Construction & Demolition Recycling Association, over 4,000 acres could be saved annually through the recovery of mixed construction and demolition materials and reclaimed asphalt pavement. Using recycled materials uses less energy and prevents the burning of fossil fuels. In conclusion, construction industries can now save 85 million barrels of oil and save the environment without processing raw materials.
  • Economic Benefits: Furthermore, recovering materials saves money by reducing disposal and transportation costs. In addition, it saves from costs of purchasing new materials and equipment. By estimate, the construction industry can support thousands of jobs at U.S. recycling facilities. Recovering materials can result in billions of dollars in economic contribution.

Construction Outcomes

When the time comes to re-design buildings or get rid of them as a whole, construction companies determine solutions to resolve projects.

  • Deconstruction: Dismantling large portions of a structure
  • Demolition: The complete knock-down of a structure
  • Renovation: Partially dismantling interior or exterior materials in order to repair and restore an existing structure.

The benefits of these construction outcomes are that companies can still enforce the idea of recovering materials. With a thorough search, you’ll be surprised to find a large amount of reusable resources. Also, workers can not only recover from these solutions but can also implement green design by building with 100% recycled materials. However, not all materials are recyclable. Nonetheless, they are still able to be reused for future construction strategies.

Recovering Materials on the Work Site

In regards to construction labor, recognizing the way workers handle deconstruction processes is important. Also, they must be aware of which materials are recyclable. How can construction laborers facilitate the process to be more efficient? When building new structures, a waste material recovery plan is highly beneficial. So, at the end of a structure’s life cycle, companies can be aware of how to handle the deconstruction process and how they can recover reusable materials. Some of these materials include:

  • Wood
  • Asphalt
  • Metals
  • Concrete
  • Brick
  • Gypsum Wallboard
  • Roofing
  • Steel

Steel is not only reusable but it is also recyclable. U.S. Bridge engineers and manufactures steel bridges from the bottom up. With speed, quality, and experience, we boost transportation for communities all across the globe. As our main building resource, steel proves to be durable, versatile, and sustainable. Lightweight and easy to repair, steel is the best material for bridges.

Green Design for Construction

More and more, companies are emphasizing resource efficiency within the industry. In fact, there is more incentive to reduce, reuse, and recycle construction waste than ever before. In fact, all across the globe there are people using eco-friendly materials and greener solutions in infrastructure. All in all, green design focuses on:

  • Protecting the environment
  • Enabling the health of people and wildlife
  • Strengthening the durability and safety of structures

U.S. Bridge builds long lasting structures and supports impacting the environment during the process. In a previous U.S. Bridge article, we share the importance of green design and sustainable bridge building.

Liberty Series Bridge Project in Peru

Liberty Series Bridge In Peru

With more than 80 years of experience, U.S. Bridge has provided countless bridges to multiple communities around the world. One of which is in a remote area in Peru. The Liberty Series bridge project in Peru required a bridge that met two requirements: to be quickly deployable and can adjust to different lengths. U.S. Bridge Liberty Series Modular Panel Bridge was the perfect solution to help bridge the gap in this community.

U.S. Bridge Provides a Solution

Odebrecht, one of the largest construction companies in the world, is responsible for maintaining 955 km of major highways in Peru. Also, part of their responsibilities often require consulting on the necessity for bridges and bridge replacement. And that is exactly what they needed in Peru, a bridge replacement with specific requirements.

Thus, they turned to U.S. Bridge for this bridge replacement. Odebrecht was looking for a bridge that in the event of an emergency could be quickly deployable and could adjust to different lengths. Additionally, these bridges needed to have the structural integrity and flexibility to be temporary (8-10 months) or permanent.

This dual requirement meant that other “panel bridge” companies were not eligible to provide bridges that met Odebrecht’s needs. Also, typical panel bridges could not be left in place permanently without requiring very frequent and expensive maintenance.

Liberty Series Modular Panel Bridge

As the largest fabricator of steel truss bridges, U.S. Bridge had the perfect bridge solution. U.S. Bridge possesses not only the in-house engineering knowledge and capabilities to provide consultation services, but also the fabricating experience and product line to meet the customer’s requirements.

After visiting U.S. Bridge’s engineering and fabricating campus in Cambridge, Ohio, Odebrecht placed their initial order. This order was for a 55 m long x 3.66 m wide Liberty Series Modular Panel Bridge. The Liberty Series met all the criteria for the dual usage requirement as well as being capable of being launched or installed by crane. Ideal for Odebrecht, the Liberty Series modular panel bridge system was designed to adjust to different lengths by simply adding or removing existing panels.

According to Alberto Marotorelli, Vice President of Odebrecht,

“We like the professionalism exhibited by U.S. Bridge throughout the project as well as the exemplary level of services provided. The assembly and installation procedures were of the highest quality and better than anything we had seen from others in the past. They provided outstanding on-site installation supervision from a USB professional who has installed more than 500 bridges himself.”

U.S. Bridge Global Operations

U.S. Bridge has completed thousands of projects in more than 50 countries. Our global operations has the mission to provide the best bridges at a fast rate. Contact us today to get more information on our bridges.

U.S. Bridge Assists in the Construction of the 41st St. Chicago Pedestrian Bridge

USB Assists In The Construction Of The 41st St. Chicago Pedestrian Bridge

At U.S. Bridge, we pride ourselves on bringing a wide range of bridge projects to life across the globe. Our high-quality steel bridges are designed to withstand the test of time while providing safe passage for pedestrians and vehicles. To that end, we were thrilled to assist in the 41st Street Chicago Pedestrian Bridge, recently erected by S & J Construction.

What the Project Entailed

Selected from among numerous bridge fabricators across the nation, U.S. Bridge was chosen to provide the temporary bridge used for the erection of the new signature pedestrian bridge. The U.S. Bridge temporary bridge was incorporated into the project to maintain traffic of the metro rail line below, and to permit a continuous work environment all while ensuring the safety of the workers and the traveling public.

Because the components were fabricated ahead of time, construction of the U.S. Bridge temporary bridge occurred over a few brief hours, minimizing construction disturbances for both Lake Shore Drive and the railroad.

The new signature bridge is designed to echo the appearance of Olmsted’s original Chicago walkways. The bridge boasts double-curved arch mono trusses that provide structural rigidity while offering resistance against high winds. As a bonus, the bridge features energy-efficient lighting and low-glare illumination. The end result is a beautiful, sleek pedestrian bridge that adds interest to the urban landscape.

A Cambridge Flat Bridge Built to Last

A Warren Truss girder bridge, features a top chord with a polygonal shape. The design is also known as a camelback. Attractive and efficient, this steel bridge is ideal for both city and country locales. Builders can choose from one, two, and three-lane options with a width range between 12 and 44 feet.

U.S. Liberty Bridges: A Rock Solid Structure

The U.S. Liberty Bridge soars above the competition. With their rigidity and adaptability to various elevations, these bridges are designed to be containerized and quick to construct in the event of an emergency. Also, they are a preferred permanent bridge. After Hurricane Maria’s devastation in Puerto Rico, U.S. Bridge built Liberty Bridges in five communities across the island. U.S. Bridge’s Liberty Series Bridges are the ideal solution to any project.

Bolted Permanent Bridges Surpass Pinned Temporary Bridges

U.S. Liberty Bridges have numerous advantages, but one of the main reasons is their prefabricated panels. Each panel is designed with a bolting system that has an infinite lifespan. In addition, bolting assures resistance to fatigue, weakness, and overloads. This system increases the sustainability of the bridge as a whole and eliminates the need for maintenance. Contrarily, the incorporation of pins into alternative type structures leads to vibration and friction with each load, and over time, more maintenance and monitoring. With its customizable panel sizes, the U.S. Liberty Bridge also spans up to 200 feet. And its larger floor panels give it the ability to support one or multiple lanes of traffic. All these features make the Liberty Bridge the preferred choice for emergency situations.

Steel Bridges & Their Impact on the Environment

Steel Bridges & Their Impact on the Environment

The United States has been relying on steel for generations, and with good reason. Lighter in weight than many building materials, steel is affordable and durable, making it a great option for constructing everything from buildings to bridges. However, at U.S. Bridge, we especially appreciate the environmental benefits of steel. Read on to learn about the big benefits associated with building bridges from steel.

Steel Is Recyclable

The environmental benefits of steel include the fact that the material can be recycled with ease. Because of steel’s unique metallurgic properties, it doesn’t degrade over time like other materials. So, the product can be melted down and recycled for other purposes, while adding less waste. In fact, steel is currently the most recycled material on Earth.

Steel Has Economic Benefits

Another reason that steel is a great building material — and an environmentally friendly one — is that it has economic benefits. Builders can put steel constructions and bridges together quickly and affordably because steel weighs less than other materials. The ability to use less expensive equipment and lifts means money is saved in the long run. Municipal governments and communities can then use these funds for other purposes, like environmental conservation.

Steel Is Durable

It’s hard to save money when you’re constantly having to repair the same buildings or bridges. One of the best reasons to use steel for these projects is that it lasts for decades. This means you won’t have to spend valuable taxpayer dollars replacing the same structures again and again. Additionally, steel is a strong material that’s unlikely to be damaged by inclement weather conditions like storms and hurricanes. Steel even holds up well in the event of an earthquake. Because steel components require less maintenance, you can save money on both supplies and labor. The fewer resources needed to maintain steel, the fewer resources required from the environment.

The Liberty Bridge: Connecting Communities In Puerto Rico

The Liberty Bridge: Connecting Communities In Puerto Rico

Created from prefabricated panels and assembled in modules, the Liberty Bridge is a proven type of structure offering profound benefits in flexibility and installation. These advantages went a long way toward helping Puerto Rico heal following the Hurricane Maria devastation.

Featuring 8-foot by 12-foot welded panels, the Liberty Series is unique in that it can be configured and installed quickly without special equipment. Made of new, domestic steel, the Liberty Bridge can be launched or set with the use of a crane. With all-bolted connections, the bridge functions without the need for pins or other proprietary parts or designs. And thanks to floor-to-truss framing connections engineered according to AASHTO LRFD Bridge Design Specification, the model offers superior stability.

Benefits of the Liberty Bridge

While the Liberty Series is created to serve as a high-quality, permanent structure, it’s also suitable for emergency or temporary bridging. If necessary, the structure can be easily unbolted and moved in sections to another location. Spanning up to 200 feet, the Liberty Bridge can support one or multiple lanes of traffic and comes with either checkered plate or anti-skid epoxy flooring. All of these features help make the Liberty Bridge an ideal choice for dealing with emergencies.

Helping Puerto Rico Heal

In 2017, Puerto Rico suffered a devastating natural disaster. A once-in-a-lifetime storm, Hurricane Maria featured 175-MPH winds and flooding and left all of Puerto Rico without power for weeks.

Additionally, the hurricane devastated the island’s infrastructure, destroying bridges in Utuado, San Lorenzo, and Juana Diaz, among other areas, leaving residents stranded and vulnerable. That’s where US Bridge came in.

A leader in bridge building and design, U.S. Bridge was proud to be able to help Puerto Rico residents recover from this difficult period in their lives. Within a mere six weeks, the company had manufactured and installed bridges in five communities across the island. The modular bridges helped bring relief to local families, connecting them with much-needed support and services.

2018 Bridge Industry Economic Projections

2018 Bridge Industry Economic Projections

Rumors have been circulating that the federal government is ready to pour a lot of funds into U.S. infrastructure. Beyond rumors, though, what is the real economic outlook for our industry? Below are some key Bridge Industry Economic Predictions and what we can expect throughout 2018.

Strong Overall Outlook

With a dropping unemployment rate and low inflation, the overall outlook for construction growth in 2018 is very positive.  General construction work is estimated to grow by five percent. More specifically, signs indicate that the Southern and Western United States will see the biggest impact on growth. While the cost of building materials is likely to rise by a little over two percent, overall industry growth is still expected.

Bridges and Roads

Bridge Industry Economic Projections estimate that bridges and roads will be the biggest growth segment in the nonbuilding sector. This is in part due to the government’s Infrastructure for Rebuilding America (INFRA) program. This program will fund up to 10 highway and bridge projects. However, it has not yet been voted on.

State by State

The overall growth of road and bridge construction may seem minimal when applied to the entire U.S. as a whole. However, some states will see more growth than others. According to the American Road and Transportation Builders Association (ARTBA), California, Florida, New York, Hawaii, Virginia, and Washington are poised to see the most local growth in the construction industry. Additionally, total spending on public bridge and tunnel construction is expected to top out around $31.3 billion, a slight increase over 2017.

Signs for a Strong Future

Most assume that the federal government will pass INFRA, adding funds to the construction industry in 2018 and early 2019. These projects would undoubtedly bring long-term growth for years to come. Further, with nine percent of the U.S.’s bridges and roads deemed structurally deficient and in need of repair, the need for bridge and roadway construction will likely continue for decades.

Steel, Our Most Sustainable Material

Steel, Our Most Sustainable Material

Steel is one of the most widely utilized building materials for a variety of purposes, including:

  • Commercial and residential building projects
  • Bridges and highway construction
  • Vehicles and household appliances

Fortunately, through decades of innovation, steel has become easier to manufacture; and just as importantly, steel is one of the most recycled and thus sustainable materials in the world.

Why is Sustainability Important?

Sustainable materials don’t deplete non-renewable natural resources during the manufacturing process. This is extremely important since non-renewable resources are only available in finite quantities. The other benefit to preserving non-renewable resources is to maintain the environment’s natural equilibrium.

What Makes Steel Sustainable?

One factor that makes steel a sustainable material is its significant reduction in energy emissions (by approximately 31 percent). One ton of steel now takes one-third less energy to manufacture than it did in 1990. Also, during steel production, carbon dioxide emissions have been reduced by 36 percent. Steel is also the most recycled material in the world, with more than 65 million tons recycled per year.

What is Life Cycle Thinking?

The steel industry has committed itself to Life Cycle Thinking. This method of analysis allows the industry to continually examine its environmental impact. Thus, Life Cycle Thinking looks beyond simple eco-friendly practices to understand the impact of steel production on all aspects of daily life. This includes manufacturing, design and production, use and maintenance, disposal and recyclability of waste and components.

Using Recyclable Steel

An estimated 93 percent of steel currently used in construction projects is recycled. Additionally, 98 percent of a building’s steel is recycled back into other steel projects once the building reaches the end of its life-cycle. This recycling happens without any degradation to the quality of the steel, making it a truly reusable resource.

We at U.S. Bridge pride ourselves on building structures that last, without negatively impacting the environment. By working with a sustainable material, like steel, we’re confident that our bridges will be around for decades without leaving much of a carbon footprint.

U.S. Bridge has worked with local and state governments and recently completed a bridge-building project in under 30 days. To discover what our professional team can do for your next project, please contact us today.
