Tips for Conflict Resolution in the Construction Industry

Unresolved conflicts in any workplace can cause a handful of lingering ill-effects such as poor morale, hostility, and inefficient work. The most effective way to handle a dispute is by being prepared with a response plan. To help we’ve compiled a list of tips for conflict resolution in the construction industry.

Addressing the Conflict

Whether passive or combative, allowing conflict to linger is deadly for workplace morale and productivity. Disagreements can easily occur in projects between crew members within a team, supervisors, suppliers, or contractors. Your first step should be to address the conflict head-on as quickly as possible with all the parties involved. The most effective way to do this is by understanding the underlying points of the situation.

Arguments are often due to misunderstandings between parties caused by poor communication or by different interpretations of the project. Sometimes the wrong materials are delivered, equipment is damaged, or a crew member isn’t abiding by company rules. This can delay productivity and jeopardize the project.

As construction sites are already a stressful environment, you might have to calm everyone down before you can get them to calmly discuss what happened. Building a timeline and talking to others helps ensure that there isn’t another underlying cause that you’ve missed that could arise again later.

Then, once you’ve identified every individual involved and their point of view you can then begin to determine how everyone arrived at their current state. 

In some instances, it is easier to keep the dispute contained, however, if the issue is more pervasive it may need to be addressed at a larger scale, for instance, throughout an entire department.

Developing a Resolution

A strong conflict resolution ensures that everyone impacted understands the decision initiated. When developing a conflict resolution on construction sites, or really in general, chances are not everyone will be thrilled with the final result. Demonstrating competence, fairness, and respect for the project and all its stakeholders will encourage others to feel confident in your decisions.

By this point, you’ve already identified the root cause. Most likely your project is comprised of various team members, so you want to build a compromise that will salvage your relationship.

But don’t just focus on the people, instead, look at the problem itself. Consider what is important vs. what is urgent for the matter at hand and the project overall. An acceptable solution often requires both disputants to compromise.

Be clear in your delivery. It’s vital that everyone understands what to expect moving forward. Once a decision is made, offer a rationalization and a follow-up to make it easier for others to accept.

Consider Proactive Measures

You don’t have to wait until after a confrontation to start thinking about how to stop fights. Businesses can take proactive steps to avoid conflicts by building teamwork and enrolling their crew in conflict resolution training. Although this may seem more costly and time-consuming in the beginning, it does save crew time, money, and face by being able to avoid conflict before it even begins. Not to mention, it leaves a better impression on others.

In the end, conflicts are going to happen in any workplace. What’s important is how you react to them. The best way to keep productivity, employee morale, and overall job satisfaction up is through a well-established plan.

Careers in Construction Month

,

All October long, organizations such as NCCER and BYF raise awareness about the diverse career opportunities in the construction industry. This event is called Careers in Construction Month and it takes place every year to help organizations reach more talented applicants as well as teach the public about the benefits presented in the industry.

The Benefits of Working in Construction

Versatility

Another big advantage of working in this industry is the extensive range of trades available. Just one project alone requires individuals from various trades like engineers, architects, masons, and many more. With so many different crafts and trades options to choose from you’re sure to find something you’ll like.

Job Security

There’s been a shortage of skilled workers for years so the demand for individuals in construction careers is high and only rising. Although the shortage causes issues such as delaying projects or not having enough manpower, it does give more people the opportunity to apply in the field. Not to mention, it provides a sense of job security.

No Degree Necessary (Degrees are Optional??)

One of the biggest advantages is that, for the most part, no college degree is required. This opens the door for many people who either chose not to go to college or were unable to afford it. However, this does not apply to every career option in the industry. For example, although a mason may not require a degree, the position of architects and civil engineer does.

Some trades, however, do require formal training or certification from either a trade or technical school but for many, you’re able to apply and join as a laborer to gain experience. Of course, like in any other industry, the more training, experience, and credentials an applicant has, the better off they will be at obtaining a job.

A More Active Lifestyle

Unlike other occupations, chances are you won’t be sitting all day. Working in construction means that you get a more active lifestyle which is better for your health. That being said, the construction industry can be very physically demanding and could have some serious negative effects on your body. Ultimately, your daily routine will be determined by the career chosen.

The Potential for Growth

Your pay depends on various factors such as location, trade, and experience. But the great thing is that there’s always a potential for growth in salary and position.

Compared to other careers, it’s fairly easy to enter a trade without experience. For many traders, you can start as a laborer and learn the craft over a few years to progress in your skills and position.

Careers in the Construction Industry

Architect

Architects are the individuals who design new buildings and construction plans. Their blueprints and concept designs include the inner structure and outward appearance of projects. This position requires a Bachelor’s Degree, Master’s Degree, or Project Management Certification. In addition, skills utilized in this career are creativity, computers, detail-oriented, math, and teamwork.

Average salary per year – $87,500

Carpentry

Carpenters build and repair frameworks and structures with wood and other materials like wood, plastic, fiberglass, and drywall. They are often involved throughout the building process from basic layout to the finishing touches. In addition to building and maintaining structures, carpenters may also play a supervisory role for framework inspection.

This career is actually among the top 10 construction trade with the highest demand. To work in this trade, individuals typically need to go to technical school, an apprenticeship program, or a trade school. Skills required for carpenters are creativity, detail-oriented, math, and troubleshooting.

Average salary per year – $56,877

Civil Engineer

Civil engineers design and supervise the construction of large-scale construction and infrastructure projects. Since one of their responsibilities is to supervise they often go back and forth from the office and project sites. This position is vital in a construction project and the pay reflects this as civil engineers are one of the top five highest-paying jobs in the industry.

This career requires education from either Bachelor’s Degree, Master’s Degree, or Project Management Certification. Additionally, civil engineers usually have skills such as computers, detail-oriented, leadership, math, and troubleshooting.

Average salary per year – $91,790

Electrician

Electricians install and maintain the electrical and power systems in new and existing structures. This means they often work with complex wiring, circuit breakers, and also large factories.

An electrician’s career generally requires a four-year apprenticeship program that qualifies individuals for both construction and maintenance work. Additionally, some electricians also attend a technical school with programs related to safety practices, electrical code, and product training. Nevertheless, most states require electricians to have a state-issued license.

Average salary per year – $67,269

Safety Technician

Safety technicians do what you would expect— they oversee safety procedures, training, and equipment. It is their job to not only identify potential risks but also develop safety plans. If an incident occurs, a site safety technician would assist with the investigation and company reports.

This role typically requires some education from a technical school, community college, registered apprenticeship program, or industry training program.

Average salary per year – $67,720

Mason

Every brick, block, or stone used to construct walls or structural supports is crafted by masons. The most common material masons use is cement. Masons will monitor drying cement and ensure that the temperature, weather, and other elements don’t prevent the cement from drying flat.

Generally, masons begin with on-the-job training and shadowing a more experienced worker or apprenticeship.

Average salary per year – $56,784

Project Manager

Just like a project manager in any other industry, construction project managers are site leaders who coordinate, budget, and supervise projects. They oversee a variety of different teams and craft professionals from the start of the project to completion. This means that they must be a team player who is able to work closely with various individuals and create detail-oriented documents.

This position requires some training in either a Bachelor’s Degree, Master’s Degree, or Project Management Certification.

Average salary per year –$92,523

World Architecture Day 2021

, ,

Not many people would think of architecture as a vital part of society but it is! It changes the world we live in so many ways. And that’s why it has its own day of celebration. Architecture Day is about recognizing its importance and the work of architects around the world.

What is Architecture Day

Created in 1985 by the International Union of Architects (UIA), World Architecture Day is an international day of architectural recognition and appreciation.

Architects, engineers, developers, and others in the industry come together in various events around the world to showcase their work, collaborate with others, and discuss current issues. Each year is a new theme to highlight areas of concern within the industry or other important topics. This year’s theme, “clean environment for a healthy world”, is inspired by the events of Covid-19.

The Power of Architecture

There are many architectural designs you’ve probably heard of like the Parthenon or Stonehenge. And although buildings and other structures give us a form of protection, how else does it impact our society?

Initially, the climate, location, and resources available dictated the shape and style of a building. However, as time progressed and technology advanced architecture began to evolve as also a representation of culture. It reflects a country’s society, values, and history. A great example of this is Russia’s famous Chapel of Saint Basil. For example, the color and design of the chapel actually hold religious meaning and represent the Heavenly City. Additionally, the nine dome-shaped structures symbolize the assault on the city of Kazan which occurred years before its construction.

Not only can it reflect a country’s past but it is also essential to planning the future. Architecture has the ability to sustain population growth and tackle a number of social problems. In fact, many psychologists are studying how architecture can affect people‘s brains. Research actually shows that the layout and color of a building contribute towards occupant health, mood, and productivity. However, blank concrete buildings can increase stress levels and negativity. To combat this, many new architectural designs include nature or greenery to positively stimulate the brain as well as the environment.

Architecture is more than just a building. It plays an essential role in a country’s society and greatly affects the people around it. Maybe next time you look at architecture you’ll perceive it as more than just a structure but as a work of art.

A Construction Crisis Management Plan

A crisis on a construction site can mean a lot of different things; a natural disaster, medical emergency, hazardous materials or accidents, and more. No matter what it is, a crisis will always have a huge impact on job sites and project funding. The best way to mitigate its effects is with a well-developed crisis management plan. But how do you plan for the unexpected?

The Importance of a Crisis Management Plan

A crisis in any job occupation is a mess and naturally the same applies to construction. It affects all subcontractors, trades, and shipments involved in the project. Plus the delay means a potential loss of money and credibility. A company or crew that can successfully navigate that kind of situation not only proves its leadership and adaptability but also leaves a positive impression.

A prompt and well-organized response will minimize the negative effects of a crisis on the project and your business.

Identify Potential Crises

In order to properly plan for something, you need to know what exactly you’re planning for. Obviously, this becomes tricky when you’re trying to plan for something unexpected. But one way to make it easier is to identify every potential crisis in a project before construction even begins. Even if it never actually happens it’s good to acknowledge every area of the project that could go wrong or that could be a potential danger to the crew. Once you thoroughly identify every potential crisis then you are able to take the next step of the planning process.

Develop a Response

With your list of potential crises, you can now begin crafting a practical strategy. The best crisis management plan is tailored to the construction project and takes location, type of construction, and external conflict into consideration. Understanding what and who is needed for each crisis early on will help you establish a well-planned and effective response. Using this information, create step-by-step templates for different emergency situations. This guide should include a list of risk factors, site hazards, and each person’s role before, during, and after the crisis.

Now, you can then begin to consider what resources such as equipment and materials are needed to address the situation. In addition, you should predetermine your evacuation routes and communication line beforehand and confirm that your crew knows as well.

Establish a Communication Line

An important part of your crisis management plan is establishing a line of communication with local off-site first-aid responders such as hospitals, police, and fire departments. Connecting first responders with construction engineers, project managers, or others who have a thorough understanding of the job site will speed the crisis response. In addition, develop an efficient method to communicate with employees and their families in emergency situations.

The coordination of a well-developed crisis management plan will help you not only handle the crisis as it happens but become pivotal in the investigation of the crisis afterward.

Train your Team

A good crisis management plan is only helpful if your team actually knows it. Training will help your team recognize their areas of weakness as well as any weaknesses in the plan itself. Include a safety checklist to determine how prepared your team and job site are for a real crisis.

Create a system or policy that confirms that training is updated regularly to ensure the best results. Conducting mock drills and training will not only reinforce the plan to your crew but also produce a prompt and well-trained response.

Consider the Aftereffects 

The crisis doesn’t just end when the emergency is over. As a business, it’s important that you have a public relations strategy prepared to avoid causing irreparable damage to the company. This plan of action should specify what you can and can’t say as well as who will be overseeing public announcements. It’s important to have a strategy in place beforehand when you have more time to think than make a mistake in the heat of the moment.

How to Find Qualifying Subcontractors

Subcontractors play a key role in any construction project so it’s important that you hire a qualifying subcontractor that will ensure your project’s success. But how do you know what to ask or look for? Here’s a brief introduction to the role of a subcontractor and what should be included in the prequalification process.

What is a Bridge Subcontractor?

In every major bridge construction project, you’ll find a general contractor and subcontractors. The contractor is the manager of most bridge projects; they are essentially in charge of the overall coordination of the project. They’re hired by a municipality or other key stakeholders, and ensure that projects meet their approval.

Subcontractors on the other hand can range from a single person to a large company and are typically hired by the contractor. However, that doesn’t make them an employee of the general contractor as subcontractors are independent businesses. Contractors can hire subcontractors for different reasons such as performing construction tasks, supplying equipment or other materials, and more.

Why it’s so Important to Prequalify your Subcontractors

Prequalification is gathering information about interested subcontractors to assess their capability to complete the project. It’s an important part of the preconstruction phase. A well-thought-out prequalification process not only reduces liability and insurance claims but presents safer worksites and increases profit potential.

This process also ensures that you are selecting the best subcontractor for the needs of your project. Although a subcontractor may be a great choice for one project it does not guarantee that they’ll be the best choice for the next.

Even though this process may initially seem like a waste of time and resources, it actually saves your project from significant financial loss down the road.

What to Consider When Looking for a Qualifying Subcontractor?

When it comes to creating a thorough prequalifying process, it’s important to request information such as the subcontractor’s safety records, finances, litigation history, insurance coverage, relevant work history, and experience, etc.

Financial

Before hiring a subcontractor, you can request financial information such as current year revenues, total and current assets, net equity, current liabilities, average monthly billings, and if available their Dun & Bradstreet number. This will reveal any obvious red flags and help you avoid financial risks.

Litigation History

A company’s litigation history is important as it provides insight into their relationship with previous clients and how likely they are to breach a contract. Find out if they’ve ever had any labor law violations, if their license has ever been suspended or revoked, and if they’ve ever been terminated from a contract. Additionally, inquire if the company has had any judgments filed against them.

Safety Records

It is crucial that you carefully review the safety records of any potential subcontractor. Request information such as their OSHA 300 information, any citations issued, and their Experience Modification Rate for the past three years. Not only that but also implore about their training program and safety plans.

Ask for References

You’ll want to ask your potential subcontractors to provide a handful of references about– three to four. These references will demonstrate how well they collaborate with other contractors on projects as well as the quality and dependability of their work.

Qualifying subcontractors won’t have any issues providing contacts, and sometimes employees can also verify the company’s credibility.

Working with U.S. Bridge

When it comes to hiring contractors or subcontractors for your project, you want to make sure that you’re hiring the best. Our 80+ years working with various companies all across the world has provided us with the skills and experience needed for even the most challenging projects.

Construction Industry Leaders: The U.S. Bridge Difference

, ,

Although there are various manufacturing companies across the country, their products and services do not include what we like to call the U.S. Bridge difference. In fact, U.S. Bridge is the oldest company in the United States to be engaged exclusively in the manufacture and erection of structural steel bridges for secondary highways under the same family ownership and management. Our great skill and quality have earned us a reputation as construction leaders in our industry.

Our Services

With over 80 years of working with companies all over the world, we know how to work in various situations and budgets. Our services include project scoping, engineering, renderings, fabrication, shipping, erection, and more. We offer services and direct communication with every step of the project.

In addition, our manufacture of Advanced Bridges (ABR) is certified by the American Institute of Steel Construction (AISC). AISC certifications are familiar to ISO standards but are specifically directed to steel fabrication. So clients can feel confident that they are receiving the best quality materials.

In fact, our permanent galvanized bridges come closer to achieving the new United States federal guidelines for a 100-year service life than any other permanent steel or concrete bridge design.

Our Difference

After successfully fabricating and installing over 3,000 bridges in Ohio, we began to expand our business. In 1987 our services extended outside of Ohio and eventually all across the country. This was when we adopted the name U.S. Bridge to demonstrate our national sphere of operations. Today we are known as construction leaders and our bridges stand in nearly all states within the U.S. as well as in Canada, Central, and South America.

Three important factors contribute to our success. First, the founder of U.S. Bridge was an engineer. From the very beginning, the creation and design of U.S. Bridge were to fit all infrastructural needs with meticulous detail. And unlike many steel bridge manufacturers, we have always maintained our own staff of engineers. This provides a great advantage of trust, speed, and affordability by removing out the middleman.

Second, not only do we fabricate bridges around the world but we also assemble our local bridges with our own employees and equipment. Once the materials ship our team assists in its assembly taking away the stress and saving time for clients. The direct communication provided in each phase of the project is what attracts many clients.

Third, the combination of design, manufacture, and erection enables us to produce more innovations than any other bridge company. This unique arrangement allows us to offer a customizable experience for our clients.

In addition to our certified quality and great communication, we also present more affordable and rapid bridge assembly. We offer prefabricated bridges that allow the use of fewer trucks and small cranes. This saves clients money and essential project time. Not to mention, our group of small, multi-skilled bridge crews (typically 3-4 welders/carpenters/operators) can achieve steel assembly in less than 7 days.

Industry Leaders

Our speed and skills are recognized and often utilized in emergency situations. We often receive requests from companies or cities all around the world for our bride designs.

As construction leaders, we have the title of first in various innovations within our industry. A few years ago we produced one of the longest bridges in Africa– a one-kilometer long bridge in Mafia Island, Tanzania.

In addition, our projects include building the first:

  • 100% hot-dip galvanized truss bridge
  • domestic truss bridge with a 35-year warranty against corrosion
  • computer-designed steel truss bridge
  • panel bridge designed that meets all U.S. permanent specifications
  • all-welded Warren truss (without rivets)
  • truss to be fully assembled in a factory
  • all-welded deck components fully prepared in a factory

Our innovations and experience explain why we surpass our opposition.

The Lifespan of Structurally Deficient Bridges in America

, ,

Have you ever driven over a bridge and wondered how old it was? In the United States alone there are more than 617,000 bridges, 12% of which are aged 80 years or older. But were all those bridges created at the same time or with the same method? What exactly is the typical lifespan of a bridge? And how many bridges are considered structurally deficient?

Contributing Elements to a Bridge’s Lifespan

Nowadays, bridges have become a natural part of everyday life. Your daily commute may even consist of traveling through a bridge or maybe two. Since they are vital to our economy and public safety, the government periodically mandates national bridge inspections to determine structurally deficient bridges.

Ultimately, there is no one number that fits the lifespan of all bridges across America. Each bridge has its own expected lifecycle but there are ways to estimate its lifespan. Generally, it’s believed that bridges are expected to function for 50-70 years however this is often not the case. Currently, only 42% of all bridges in the United States are at least 50 years old.

The lifespan of a bridge differs according to its design, construction, and location. Each component contributes either positively or negatively to the overall lifespan and structure of a bridge.

Materials

One of the most obvious factors that contribute to the lifespan and eventual structural deficits of a bridge is the material. In fact, both the concrete industry and the steel industry claim several advantages above the other for the Life Cycle Costs of a bridge.

Steel

Steel is a popular construction material due to its flexible and durable nature. The great thing about steel is that it is recyclable and still maintains its initial strength and integrity. Galvanized steel is even more durable plus it requires less upkeep.

Structural steel is a high-quality material that is readily available worldwide in certified grades and produced in various shapes and sizes. Currently, it is estimated that steel bridges have a lifespan of over 100 years. However, this number rapidly decreases as the bridge erodes or even with poor construction quality.

The deterioration of a bridge is created by a combination of several elements, for steel, it is often caused by corrosion, fatigue, stress corrosion, and damage from accidents.

Concrete

Another commonly utilized material is concrete. Concrete bridges are estimated to have a lifespan of over 100 years, again this number changes with daily wear and tear.

The causes of concrete deterioration are typically cracking, spalling, scaling, corrosion, and damage from accidents. In addition, cracks over reinforced steel allow water and chemicals to penetrate accelerating rusting which exerts great forces that pop the concrete.

Not to mention, extreme weather conditions, the presence of chlorides in de-icing salts, and cycles of freeze and thaw all contribute to the erosion of a bridge and its lifespan.

Timber

Timber, which is used for short-span and rural areas or pedestrian bridges is estimated to last only 20–30 years. This could be due to several reasons such as many engineers are less familiar with this material than their counterparts, or because there are fewer treatment options available for timber.

Nevertheless, the accurate range of which timber lasts is uncertain as there are very few data that exist that are based on actual performance data.

However, that doesn’t make timber a poor option. Timber is a lightweight material compared to concrete but still strong. This advantage plus low maintenance and repair costs make timber ideal in certain situations.

Plus studies suggest that timber is a durable option in highway bridge superstructures and that it can perform well for more than 70 years when properly pressure-treated with preservatives.

Location

The location of a bridge plays an instrumental part in its overall structural deficiency. Depending on the environment, it could accelerate the deterioration of the bridge.

Recently, there has been a slightly positive trend in addressing the maintenance of structurally deficient bridges. However, progress is not universal because states face different challenges when it comes to maintaining, repairing, and replacing bridges.

Urban

When it comes to urban locations, the major factor to watch out for is a higher traffic volume. The combination of a heavier load and volume further leads to the wear of the bridge. There are various ways for builders to slow this process down such as galvanization and other special treatments.

Rural

Unlike urban settings, rural bridges don’t have such a large volume of traffic. Unfortunately, it is because of this that rural bridges are typically not designed to withstand the growing numbers and weight of traffic and freight trucks. In actuality, rural bridges and transportation play a key role in our economy’s success and for rural communities.

However, more and more bridges in rural communities are experiencing rapid deterioration without the proper care and maintenance to last.

Coastal

Bridges that are located in coastal environments face unique challenges due to their location. Bridges in marine environments often experience corrosion-induced damage due to high sea salt and humidity. In addition, strength loss in the splash and the tidal zone is more common and significant than in the atmospheric zone.

An example of the distinct problems faced by coastal bridges is illustrated by the Morandi Bridge in Italy. In 2018, this cable-stayed bridge suddenly collapsed causing the death of 43 individuals. The collapse was reported as the fault of a weakened cable that deteriorated from corrosion. The degradation was caused by atmospheric agents and the proximity of the marine environment eroded the structure and integrity of the bridge.

Structural Deficient Bridges in America

Structurally deficient bridges are those that are in need of repair or maintenance due to the deterioration incurred throughout the bridge’s lifetime. Recently, 7.5% of highway bridges were designated structurally deficient. This is a striking improvement from the previous 12% record. In addition, the average age of America’s bridges is increasing to 44 years.

The plan is that the overall lifespan of a bridge should increase over time as more techniques, treatments, and designs are discovered in the future.

The Best Practices in Bridge Management

Proper bridge construction management is necessary to keep a project organized and completed within the budget and schedule. However, managing such a large project such as a bridge’s construction may seem daunting, so we’ve listed some of the best practices for maximizing your chance of success.

Determine the Scope of the Project

Like in any other industry, proper management is essential to a construction project’s success. What’s the best way to pre-plan your project and effectively manage it? Well, a great solution is by working with key stakeholders to determine an accurate scope of the project.

Understanding the scope is one of the first steps in the successful management of bridge construction. This means taking the time to create a thorough breakdown of what’s required for the project such as:

  • Identifying what is within or out of scope.
  • Noting the work required, the team performing the work, and the schedule of its completion.
  • Include any important elements that may impact the outcome.
  • Determining the constraints that might limit or negatively impact the outcome of the project such as resources, procurement issues, timing, etc.

Once you work out the scope, you can now move on to planning project decisions such as deck construction, railing criteria, live loads, etc.

Start Creating Plans and Strategies Early

Your planning process is essentially how you will achieve the goals set out within the scope. The reality is that while a project of the highest quality scope, at the lowest price, done in the least amount of time is ideal, it is difficult to achieve. Hence, a strategy-based process is necessary to achieve your overall objective.

Understanding your project’s success metrics is key to streamlining the decision-making process. In other words, determine project components such as feasibility, procurement, construction, close-out, and more to effectively work towards accomplishing the goal. In addition, as the project progresses you should continually refer to your detailed scope to determine if there are any changes and how they will impact the project. Recognizing and implementing adjustments in a timely manner will help reduce delays and risks.

This means start planning long before the actual construction begins, and continue revising until the end of the project. The design, pre-construction, and procurement stages of a construction project all require meticulous planning — and may need to be revised as the project progresses.

A properly planned out and scheduled project is a well-managed and successful bridge project.

Ensure Quality Construction

The quality of the construction is a big part of its success and reflects your skills in bridge management. Thus, in your planning process, you want to consider options that will create lasting effects. Consider utilizing durability solutions such as special enhancement and treatments. Galvanized or weathered steel is a popular option to slow the process of deterioration.

Not only should you be deciding what materials and methods to use, but who the manufacturer should be. Supply chain management helps you stay organized and save money. This means careful management of suppliers, manufacturers, distributors, contractors, and designers.

Pay attention to the order and delivery of materials on-site, the selection of contractors, their involvement in design and planning, and methods used to reduce invoice and transaction costs. In addition, reinforce collaborative methods with those involved in the project to keep the system flowing. This will encourage proper accountability, support, and incentives from supply chain partners.

Starting a project with these practices in mind minimizes disputes and delays. Not to mention, it improves safety and business practices and develops better project relationships.

A Globally Booming Bridge Construction Market

,

With the sudden outburst of COVID-19 last year, many individuals were concerned about how it would affect the economy. Despite the negative effects of the pandemic, studies indicate a steady rise in the global bridge construction market.

Here’s a quick breakdown of the bridge construction market and what factors affect its growth.

The Construction Market

The construction market consists of sales made in the construction industry such as construction services and goods by organizations, sole traders, and partnerships that construct buildings or engineering projects (e.g., highways and utility systems).

What Does a Bridge Engineer Do?

, ,

Bridges play a key role in our lives by connecting our communities, promoting commerce travels, and contributing to our country’s economic development. But who designs these bridges and what does a bridge engineer do?

Bridge Engineers

Bridge Engineers are civil engineers responsible for designing and building bridges and other highway-related structures. Typical tasks for bridge engineers include designing and maintaining bridge structures, minimizing environmental impact, and supervising the fabrication process. As well as completing site investigations, data collection, identifying environmental risks, analyzing manufacturing processes, supervising construction, and more.

Although the exact duties of a bridge engineer may differ, it’s safe to say they’ll always play a critical role in any bridge construction project.

Designing and maintaining a bridge is no easy task. That’s why bridge engineers are required to have skills such as analytical thinking, leadership, supervisory skills, organization, and creativity. Not to mention, time management and budgeting skills which are essential for projects with restricted time or resources.

Bridge Engineering: It’s All About The Details

Meetings & Details

Naturally, the first part of any construction project is understanding the full scope. This meeting typically covers topics and details such as bridge series and styles, special enhancements or treatments, railing criteria, etc. This will help the bridge engineer to draw up some preliminary sketches of the bridge’s general framing plan, bridge geometry, and basic construction.

These designs help illustrate the bridge and prepare the project for its next step.

Digital Renderings

One of the most powerful tools for bridge engineers to utilize is technology. Bridge engineers will often use computers to create virtual models to assist in visualizing a project. This helps the team picture the visual impacts of the bridge to any given site as well as the aesthetic qualities. Our bridge engineers are able to model your proposed bridge over a digital terrain model or incorporate it into photos of your existing site.

This aspect is extremely useful, especially if a construction project requires models to help stakeholders buy-in or make a sale.

Final Process

Once a commitment has been made, the design process officially begins and a team is assigned. The project engineer analyzes the proposed bridge including the specified design loads and appropriate load factors, along with applying numerous code checks. Eventually, the bridge engineer begins to sketch the design details and information for the designer. These sketches convey all the information previously discussed and finalized.

The engineer will also markup the general notes and list the design assumptions and pertinent bridge data onto the title sheet.

Part of this process involves reviewing the design calculations and construction plans to verify the scope and specifications. Also checked is the plan content to ensure it reflects the engineer’s design intent and that no conflicts exist and that no omissions have occurred. The final step before submittal is usually the application of the Professional Engineer’s seal and signature.

Ohio’s Construction Boom

Ohio's Construction Boom

Economic forecasters predict a slowdown in the construction industry. However, this does not seem to apply to Ohio’s metropolitan area. Our buckeye state is experiencing a construction boom with more than $4 billion in new starts (this year) including nonresidential, residential, and public works projects. According to the president of the Central Ohio chapter of the Associated Builders and Contractors, the Columbus area has become the place to do business. So, in order to accommodate the influx of residents, construction companies are hard at work. U.S. Bridge is an Ohio native bridge company. Our mission is to serve communities by engineering and manufacturing steel bridges.

Numbers Don’t Lie

Throughout 2019, Ohio saw an increase in starts. Between April 1, 2010, and July 1, 2018, the population of Columbus grew by 13.1%, according to the U.S. Census Bureau.

  • In 2019, nonresidential starts were at $2.6 billion – an increase of 38% from the same period in 2018
  • During 2019, residential starts were valued at $1.4 billion – an increase of 6% from 2018
  • Combined, these numbers amount to a 25% surge in new starts

The numbers are a telling indicator of the need for construction. In fact, at least 300 new projects are in the works for this busy metropolitan area. The modern job market is attracting more and more people, which demands ongoing construction. This includes the healthcare projects and further construction labor taking place at Ohio State University. Additionally, the dollar value of new starts has circled the total for the years of 2008 through 2014! Columbus is experiencing both a population and construction boom that is expected to continue at a quick rate.

Skilled Laborer Shortage

The continuous increase in the city’s population has brought upon a serious issue. There aren’t enough skilled trade laborers to take on the challenge. This inadequacy is driving an increase in project costs and completion times. According to the Associated General Contractors of America, the data released from their new survey claims that Ohio construction firms are expecting the construction boom to continue; 90% of companies report that they plan to hire additional workers throughout 2019. However, 88% of that population expect the hiring process to be a challenge. Unfortunately, this has become an issue of qualified workers on top of the existing shortage. Studies show that over one-third of firms agree that a lack of qualified talent is hindering the successful and timely completion of construction projects.

Solutions to Combat this Issue

33% of Ohio state respondents say they are using methods to reduce on-site work time. This includes:

Columbus Construction Boom

While the issue of worker shortage remains, construction in Columbus continues to attract new and existing citizens. So much so, companies such as Google, Amazon, and Facebook are also participating in the construction boom by extending their headquarters to the Ohio metropolitan area. The city has become known as a modern technology hub, attracting wide groups, especially millennials.

Hot-Dip Galvanized Steel vs. Weathering Steel: What’s The Right Choice?

Hot Dip Galvanized Steel Vs. Weathering Steel What's The Right Choice

Steel has long played a key role in American construction efforts. Not only is steel lighter in weight than many other building materials on the market, but it also earns points for durability, affordability, and environmental friendliness. Still, bridge builders may struggle with whether to use more traditional weathering steel or increasingly popular hot-dip galvanized steel. Read on to discover how these options stack up.Hot Dip Galvanized Steel Vs. Weathering Steel What's The Right Choice

Benefits and Drawbacks of Weathering Steel

Long a favorite among bridge builders, weathering steel offers numerous advantages over other building types. Strong and attractive, this material rusts in a way that provides protection against the elements. Builders refer to this as “useful corrosion.”

Still, the news about weathering steel isn’t all positive. Progressively corroding, weathering steel can deteriorate faster if moisture is present. To compensate for this loss of mass and strength, builders may need to use thicker sections of steel from the start. Additionally, salt air and humidity can damage weathering steel, resulting in accelerated corrosion.

Benefits of Hot-Dipped Galvanized Steel

Formed by dipping bare steel in molten zinc, hot-dip galvanized steel is a popular choice in bridge construction. Featuring the strength of weathering steel, hot-dip galvanized steel offers additional benefits, too. Barrier and cathodic protection mean that this material resists corrosion. As a result, this option requires less long-term maintenance than weathering steel. Additionally, hot-dip galvanized steel maintains its structure despite exposure to UV rays, snow, water, and soil and is 100 percent recyclable.

The Economic Benefits of Bridge Building

The Economic Benefits Of Bridge Building

Most of us don’t notice much about the bridges and roads that connect our cities and states. However, we would certainly notice if we woke up one day and they weren’t there. Bridges play a crucial role in various aspects of modern life, enabling us to get to work or school and contributing to the country’s economic development. This, of course, is something the American Society of Civil Engineers knows well. Every four years, this all-important group releases a bridge report card, assessing how these structures are holding up. Read on to learn more about bridge economic impact and what we can do to protect these structures moving forward.

Aiding in Infrastructure

Bridge economic impact starts with the way they support the transport of people and goods. Along with allowing companies to ship materials, bridges enable consumers to travel to shops and malls and visit new cities as tourists. When a bridge goes down, the surrounding area experiences a halt in economic activity, as people can no longer purchase goods and services with the same ease.

Supporting the Local Economy

Bridges also support the local economy, thanks to wages paid to construction workers and repair crews. Even the most well-designed bridges require regular cleaning and maintenance. Bridge workers then give this money back to the local community by paying taxes and purchasing local goods and services.

Connecting Communities

Bridge economic impact issues go beyond simple cash flow. Bridges connect people in different communities, allowing them to interact for work or play. This capacity is especially essential for areas where one town has an abundance of raw materials and another has a labor force in need of work. In this way, both people and communities can support one another.

What’s to Come for Our Nation’s Bridges

In assessing the country’s bridges, the American Society of Civil Engineers determined that the average bridge age is rising. As result, the United States will need to spend $120 billion or more to complete the necessary repairs and get all the bridges up to code. That’s where companies like U.S. Bridge can help.

Bridge Floor and Deck Construction

Those who aren’t familiar with bridge building might think of decks as parts of a ship or the area in the backyard where grills are kept. However, in the industry, we know “deck” is a term for the driving surface of a bridge. Whether constructed from concrete, wood, steel, or open grating, decks that form the driving surface of a bridge need to be strong enough for traffic to cross safely. At U.S. Bridge, we provide a full range of sustainable bridge floor and deck solutions to clients throughout the world. Read on to learn more about the types of decks we offer:

Concrete Deck Slab

When it comes to bridge floor and deck products, the concrete deck slab is one of the most popular. Typically between 7 and 9 inches thick, this deck has two layers of steel reinforcing bars to provide strength and durability.

Asphalt

For this deck type, corrugated steel planks, 3, 5 or 7 gauge, are attached to the stringers of the bridge and become a structural component of the structure.. By galvanizing these planks, the flooring is protected against corrosion. With an asphalt overlay, these types of decks provide a long-lasting, economical, driving surface.

Open Grid Steel Deck

If weight constraints are an issue, open grid steel decking is a wonderful option for a bridge floor. It is characterized by whether the grid is filled, or partially-filled with concrete. If concrete is included, a metal pan or form is included near the base or at mid-height of the grid to support the concrete while it cures.

Precast Concrete Panels

One of the most efficient deck types, precast concrete panels can be constructed quickly and easily. Designed and manufactured off site, these panels can be installed one day and driven over the next. Non-shrink grout is mixed and poured in batches on site.

Nail-Laminated Timber Bridge Floor

Ideal for more rustic locations around the country, these timber decks utilize pressure treated lumber to protect against the elements. Additionally, buyers can opt to cover the deck with asphalt if they choose.

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.

Hurricane Maria Statistics in Puerto Rico

Hurricane Maria Statistics In Puerto Rico

Immediately following the Puerto Rico hurricane, 100 percent of the island was without power. Additionally, parts of the island had become completely isolated due to the loss of bridges and roadways. Many of these structures were either swept away by the storm or deemed unsafe to travel in its aftermath. U.S. Bridge is proud to be part of the rebuilding effort in Puerto Rico. Take a look below to understand the full scope of the damage to Puerto Rico.

 

A Once-In-A-Lifetime Storm

Hurricane Maria devastated Puerto Rico for almost three weeks. The Category 5 hurricane had wind gusts of up to 175 MPH and is responsible for more than 1,000 deaths. With such an intense storm assaulting the island, its infrastructure was ill-prepared to handle the amount of flooding; as a result, downed trees and power lines made many roadways impassable. Plus, the lack of power leftmost Island residents without access to refrigerated food and medicine, and with only limited access to news and information regarding the storm.

Rebuilding Roadways

U.S. Bridge built five Liberty bridges in Puerto Rico. The effort required 800 metric tons of steel, all made in the USA, as well as three contractors. Altogether, these bridges accounted for 950 feet of roadway with a design life of 75 years.

USB PR Stats Update May20 2018

Reconnecting Communities

The five bridges are in areas hardest hit by the Puerto Rico hurricane. These areas are:

Each of these bridges passed rigorous requirements as set forth by FEMA, AASHTO and the Federal Highway Administration (FHA). The work in Puerto Rico required the use of three freight companies, two galvanizing companies, and two ship lines.

USB-PR-stats-communities-update-May20-2018

Delivering Relief

U.S. Bridge estimated that the building of the bridges took six weeks. In under two months, U.S. Bridge provided Puerto Ricans with just some of the relief needed to rebuild their lives.

As a leader in bridge design and manufacturing, U.S. Bridge is proud to serve as part of the rebuilding effort. The Puerto Rico hurricane was an unprecedented weather event, and our team of engineers is eager to bring their knowledge and expertise to the task at hand.

Puerto Rico Hurricane Damage Coverage – U.S. Bridge To Build 4 Bridges

Puerto Rico Hurricane Damage Coverage - U.S. Bridge To Build 4 Bridges

Since Hurricane Maria devastated Puerto Rico, its residents have been waiting for life to return to normal. However, with its infrastructure severely damaged by the storm, a normal way of life is all but impossible. That’s where U.S. Bridge comes in. They are working on the ground to combat Puerto Rico hurricane damage by rebuilding bridges in four affected areas.

Reestablishing Connection

Hurricane Maria caused massive mudslides, trapping some people in their homes for days and weeks following the storm. These mudslides also led to bridges collapsing. This made it impossible for people to access basic necessities like food and water. Roadways that were once traversed daily were now impassable. U.S. Bridge, started at the end of 2017, and is in the process of finishing in March of 2018. Some of the first rebuilding efforts are focused on affected areas like Utuado.

Reconnecting Remote Areas

Puerto Rico hurricane damage greatly impacted remote areas of the island in these regions, such as Juana Diaz, Utuado, Moca, and San Lorenzo, Morovis. In total, more than 100 of the bridges in Puerto Rico were damaged, and 18 have closed. Without these bridges, residents in remote areas are stranded. Residents are only able to get food and water through pure ingenuity. For example, residents in Rio Abajo, who are now completely cut off from supplies, have rigged a pulley system to get supplies across the river. Due to U.S. Bridge’s quick turn around time, they immediately engineered, manufactured and shipped their Liberty Series bridges to these communities. They are being built as this article is being written! Tactically, U.S. Bridge is connecting one part of the island to another.This will bring hope back to  the area and hasten the flow of supplies that residents so desperately need.

Working Together for Everyone

U.S. Bridge is proud to be one of the many companies working diligently to combat Puerto Rico hurricane damage. Crowley is another great company that is helping transport major components of the Liberty Series bridges across the region. Federal organizations like FEMA and FHWA (Federal Highway Administration) have also backed and supported the recovery effort in Puerto Rico. 47 containers are being transported. These containers weigh in at around 800 metric tons of steel. In total, more than 880 feet of bridge will be built. U.S. Bridge is confident that citizens will regain a semblance of normalcy. These four bridges are being constructed in some of the hardest hit areas of this beautiful island. The work in Puerto Rico has just begun. Collaborative efforts like this are a perfect way to push the rebuilding movement forward.

These amazing contractors should be applauded for their work on these projects:

Liberty for Puerto Ricans

Local news in Puerto Rico is starting to see the benefit of what U.S. Bridge and their partners are doing. Below is a story from Wapa.tv on the Utuado bridge and local residents’ reaction.

 

An Engineering Leader Helping Puerto Rico Hurricane Damage

For over 80 years, U.S. Bridge has been a leader in bridge design and manufacturing throughout the world. Our team of engineers works with local and state governments, businesses, and other organizations to reinforce and stabilize bridges across the country. The CEO of U.S. Bridge, Dan Rogovin and COO, Rajat Shah, have been in Puerto Rico, assessing progress and lending their support.

Todd Carpenter, Bridge Superintendent at U.S. Bridge, has been in the country overseeing the work, and said, “the collaborative effort from, the contractors, the U.S. Government, and the people of Puerto Rico, has made this an extremely fulfilling project. Knowing that our bridges are being used for connecting communities that were shattered, is something I’ll never forget. And these communities will use these bridges for generations to come.”

Hurricane News: Damage Coverage For Puerto Rico

Hurricane News: Damage Coverage For Puerto Rico

Hurricane Maria devastated Puerto Rico in mid-September 2017. The island’s infrastructure relied on bridges, roads and waterways to maintain trade. Unfortunately, most of these bridges and roads have been destroyed and are no longer passable, according to hurricane news reports. These modes of transportation also provided Puerto Ricans with access to food, water, gasoline, and cities. Hence, rebuilding efforts are the key to getting the island back on its feet.

U.S. Bridge has followed the hurricane news very closely and is eager to help the people of Puerto Rico. Lacking resources and any way to transport them to people who need them most, U.S. Bridge is determined to help Puerto Rico by rebuilding bridges to facilitate free movement of food, water, and gasoline. Parts of Puerto Rico won’t have power before late May, 8 months after hurricane Maria. About 95 percent of the island will see energy restoration by the end of March. Things are slowly getting better, however, there is still much to be done.

Unable to Navigate the Mountains

The mountains near San Juan were particularly hit hard. For example, the neighborhood of San Lorenzo has been cut off from the city due to the destruction of a bridge that allowed free passage for its residents. Residents in the area have stressed how important it is for them to be able to move freely between their homes and the city. Elderly people and the sick, for instance, no longer have access to the care they need. The only option is to ford the river in what is often waist-deep, murky water. On the other hand, they may take a path around the mountain that can add three hours to their trip; but with limited access to gasoline, this is not a viable option. Some residents have actually rigged a cable above the water to get supplies across.

Built to Last

U.S. Bridge is eager to provide relief to the people of Puerto Rico. U.S. Bridge will be using the Liberty Bridge design for four bridge projects that are contracted to construct in Puerto Rico. This bridge type is made up of prefabricated modules that are easy to transport and assemble.  Based on the hurricane news, the Liberty Bridge will offer the type of permanent and quick relief that the people of Puerto Rico need.

U.S. Bridge is providing bridge-building expertise to the people of Puerto Rico who are still suffering the effects of Hurricane Maria more than four months after it made landfall. For more information about U.S. Bridge and our team of dedicated engineers, please feel free to contact us for more information.

Steel vs. Concrete White Paper

Analyzing the life cycle costs of steel vs. concrete bridges is of utmost importance to U.S. Bridge and the infrastructure industry in general. Aside from sustainability and social responsibility, U.S. Bridge is dedicated to using the best materials for the job. Depending on the scope of work and bridge design, the choice between steel or concrete could have a long-lasting impact on the sustainability of the structure.

U.S. Bridge asked Michael G. Barker Ph.D., a professor at the University of Wyoming, to draft a white paper regarding the Life Cycle Costs Analysis (LCCA) of bridges. Of particular interest was the use of hot-dip galvanized steel vs. concrete. The study determined that using HDG steel reduces capital costs by 8.5 percent. Below is the executive summary of the report that provides a good snapshot of the report and its findings. You can download the entire white paper here.

Executive Summary

Since the early 1990s, the Federal Highway Administration (FHWA) has promoted the consideration of Life Cycle Costs Analysis (LCCA) in the design and engineering of bridges. LCCA determines the “true cost” of bridge alternatives considering the time-value of money. The Life Cycle Cost analyses employed in this study uses the Perpetual Present Value Cost (PPVC) of bridge alternatives for an equivalent comparison between the alternatives.

Over the years, the author has worked with state departments of transportation and local county engineers on effective and economical bridge construction. A frequent question that arises during meetings is the difference in Life Cycle Costs between steel and concrete girder bridges. Both the concrete industry and the steel industry cite various anecdotal advantages above the other for the Life Cycle Costs over the life of the bridge. There has historically been a healthy competition between material types for new bridge construction. However, there is industry and owner confusion on how the different types of bridges compare on a Life Cycle Cost basis.

Steel vs. Concrete Bridge Analysis

This study developed useful owner information on historical Life Cycle Costs for typical steel and concrete state bridges in Pennsylvania. Typical bridges defined in the study are:

  • Concrete decks supported by steel rolled beams
  • Steel plate girders
  • Precast concrete boxes
  • Precast concrete beams

PennDOT historical records for bridges built between 1960 and 2010 were used to develop the Life Cycle Cost study database. Initial and maintenance costs considered include total project costs (more than just superstructure) as recorded in the PennDOT records. The PennDOT database used for the Life Cycle Cost analyses only includes a subset of the total bridge inventory. Missing cost and date data for a majority of the individual bridges made total inventory impossible. The database consists of 1,186 state bridges out of 6,587 (18 percent of the eligible inventory) built between 1960 and 2010.

The initial costs, Life Cycle Costs, and future costs of the 1,186 bridges in the database are examined with respect to:

  • Variability in bridge type
  • Bridge length
  • Number of spans
  • Bridge life

Protective coating systems were also used to examine steel bridges. The results must be taken into context since the results only represent the bridges that made it into the database. The database is not as comprehensive or desirable for drawing conclusions. The reader must decide how to interpret the tables and figures showing comparisons of initial costs, Perpetual Present Value Costs, maintenance and future costs, and bridge life.  

Report Conclusion Summary

A conclusion that can be drawn is that all the types of bridges are fairly competitive in both Initial Costs and Perpetual Present Value Costs. The average initial costs vary from $174 per square feet to $226 square feet. The average Perpetual Present Value Costs vary between $218 per square feet (Prestressed I Beam) and $278 per square feet (Prestressed Adjacent Box). The lowest average bridge life was 73 years (Prestressed I Beam) and the longest was 82 years (Steel I Beam). The coefficient of variation (standard deviation/mean) of the PPVC was approximately 20 percent, which is considerably high. With the relatively small differences in the PPVC averages, given the dispersion of the PPVC costs (standard deviation), any of the bridge types may have the least Perpetual Present Value Cost for a given project.

Chance for Further Study

This research was limited to a subset of PennDOT bridges. However, the analyses demonstrate the potential benefits of LCC analysis for bridge construction and management. A study of a more comprehensive database of bridges on the initial costs, Life Cycle Costs and future costs of different types of bridges over a diverse set of circumstances would be very useful for bridge owners and managers. A more comprehensive database would allow for a more accurate comparison of bridge types, design details, such as jointless decks, rebar coatings, steel protection systems, and other construction details.
