Major Challenges in Wastewater Management

Wastewater Management

Wastewater treatment systems are designed to treat used water so it can be recycled safely and put back into the environment. Advances in technology have begun to make these processes more streamlined than ever. These advances do not mean that there are not challenges to overcome when it comes to wastewater management.

Energy Usage

Energy requirements necessary to operate a wastewater treatment plant is one of the biggest challenges they face. The wastewater filtration process consumes between 3 and 15% of the nation’s electricity annually.

Many wastewater treatment plants need upgrades throughout the United States. Here are some of the biggest challenges ahead and some potential solutions to fix them.

Recently efforts have been focused on discovering greener approaches to treating wastewater. By incorporating greener processes, we can reduce energy consumption and lessen the overall strain to the power grid.

Staffing Issues

Similar to other industries, finding qualified plant operators has become a challenge. Properly trained workers skilled in the process of wastewater treatment is a must. There are not enough employees to go around. Another aspect of this issue is that typically treatment facility operator management can account for up to 30% of annual operational costs.

Finding ways to incorporate automated processes and remote operation tactics may help. Such improvement will help reduce the reliance on employees as well as labor hours needed. It may not fill in the gaps in employment needs or reduce all operation costs, but it would lower the stress and burden on existing employees and budgets.

Sludge Protection

Sludge is the residue generated during wastewater treatment. A major challenge environmentally for wastewater treatment facilities is how to dispose of this excess sludge produced during the process.

Safe and long term solutions for sludge disposal is an essential component of any properly operating treatment facility. Sludge can be recycled and used in agricultural applications because it contains organic matter and nutrients useful to agriculture.

Treatment Plant Environmental Footprint

Though wastewater treatment plants are designed to filter water and make it eco-friendly, they can leave their own environmental footprint from the treatment process. In simplest terms, the organic matter removed from the water needs to go somewhere.

There have been recent improvements in green technology that improve the way water is being treated. These innovations will help reduce the environmental footprint left behind by water treatment facilities from disposal of what is left behind after clean water has been discharged.

These are, by far, not the only challenges facing treatment facilities and the process of wastewater management. These particular areas are the most glaring and most impactful. We recognize the many issues facing local municipalities and private industry when it comes to wastewater management. BE Structural is here to help find innovative ways to address these challenges with engineering services for wastewater treatment facilities and large equipment supporting biosolid technology.

2020 Structural Engineering Trends

Structural Engineering Trends for 2020

The world is continually evolving and changing around us as each year passes. One group that feels the impact of this change is structural engineers.

Structural engineers are deeply involved in how to develop the areas we live in and the structures in which we live and work. They are required to meet the shifting demands of our ever-changing world. To meet the demand, solutions are needed, and these solutions develop into yearly trends. Looking to 2020, here are a few trends that seem likely to take shape.

Funding and processes

Innovations in technology are being rolled out at an unbelievable pace. These advancements allow both engineers and builders to streamline their processes. By improving processes, this enables teams to lower overhead and turn around jobs more quickly and efficiently.

Going green

As technology improvement has developed, one of the areas most impacted is the environment. New techniques are allowing structural engineers to take advantage of methods that reduce energy consumption on new projects. The benefits of these changes will be seen and felt for decades to come.

Modular construction

Though not necessarily new, modular construction continues to be an innovative way to design and construct buildings more quickly without sacrificing their integrity and safety. This process is mainly employed in the commercial building industry where box units are either stacked or set side by side.

More recently, modular construction methodologies have begun to be used on residential projects such as basement construction for new homes. There are even areas where entire sections of the home are built off-site and assembled on the foundation, reducing time and labor.

Zero waste practices

Not necessarily a new trend, zero waste practices are becoming more prevalent and look to be more widely adopted. Adopting zero waste practices benefits all involved as it reduces waste when certain materials see their end of life functionality. By incorporating methodology that
takes this into account, parts can be replaced rather than disposed of entirely. One example would be using bolts rather than welds. The benefit of this method is that in future expansion, bolts could be reused rather than entire welded sections needing to be demolished.

Sustainable materials

As a desire for sustainability has increased, so has the progress of new methods of construction. Structural engineers have designed and implemented technology to improve building safety. One example is systems designed to detect seismic activity in areas prone to earthquakes. This technology allows the buildings to detect and react to changes in the earth as they occur. As if this were not enough, engineers have also more recently designed 3D printing and concrete that, upon damage, can repair itself!

As technology continues to advance, it will be interesting to see what the future holds for the engineering process and building improvements. As in the past, these advancements will be exciting to watch develop and even more beneficial to us all. BE Structural is positioned to take advantage of these advancements as they occur. Contact us today to see how we can work together and take advantage of these new trends.

Ten Questions to Ask a Structural Engineer Before Hiring

Is your business in the beginning stages of planning a major project? Here are ten questions to interview potential structural engineers and make sure you hire a reputable company.

What specific field do you specialize in?

Does your potential structural engineer specialize in residential or commercial building? State and local codes for each are different, so it’s important they are familiar with your specific type of project. Find their website and look at their “Our Services” or similar to see exactly what work they do.

What projects have you completed?

The projects the firm has completed can serve as a good indication of how they service their clients. Do they focus on residential, short-term projects, or more involved long-term projects that require detailed reporting and monitoring? It would be a good idea to call them and ask for references from previous projects so you can get an idea of their scope of work and capabilities.

Are you aware of local code requirements?

Construction requirements change frequently. Ensure the firm you are researching is up-to-date on all local and state building codes. This will alleviate a lot of headaches during your project.

How do you collaborate with other contractors on the project?

Ensure the firm can work alongside any builders or contractors you would prefer to hire for your project. When checking references, find out how timely the structural engineer is at replying to emails or returning calls. See what hours they are available including after hours and weekends. Also, check to see what their holiday hours are if your project will overlap a holiday. The last thing you want is contractors to be awaiting input from your structural engineer.

How do you invoice projects?

Request a letter outlining the structural engineer’s fees. Also, ask for a quote in advance of any work. If you have already defined the majority of the scope of your project, ask for a fixed design fee. Throughout your project, be leery of unexpected charges that arise and question them. Check to see how the firm typically expects payment. Do they require payment before releasing their final product, or do they set up accounts?

What are your qualifications?

Ask to meet with whomever your likely point of contact would be for your project to discuss their background and qualifications. You should feel comfortable communicating with this person and in their ability.

Does the structural engineer understand the scope of the project?

Request confirmation that they understand the scope of work, their involvement in it, deliverables, and expected deadlines.

Can you provide proof of insurance?

Structural engineers need to carry some level of liability insurance. Don’t be afraid to ask for a copy or other proof of coverage. It should be up-to-date and cover the type of work your project entails.

Do you have any repeat clients?

Repeat clients is a good indication of a structural engineer’s trustworthiness and work ethic. Review project types as well to assure they match the scope of work you are looking for. For instance, repeat residential clients may not signal an understanding of commercial project knowledge..

Do you have references we can contact?

Reputation matters, and if you ask around in your community you will find out pretty quickly how your potential structural engineer is perceived. In addition to talking to other clients, check the company’s online reviews for an unaudited look at their abilities.

Current Trends in Solar Energy

As climate change continues to wreak havoc on our temperatures and sunlight, more and more people and businesses are becoming aware that solar energy is a great way to be environmentally friendly. From small families to big corporations, the benefits of solar energy are endless and provide an easy and affordable way to help sustain the environment we live in and depend on. Not only is this renewable energy great for the environment but the financial benefits are abundant. There are so many great things happening in the solar industry.

Farming

With the decline in farming due to cost, a dairy farm in California, Lima Ranch Dairy, is combatting this problem by using solar energy. By reducing their operating costs, they can ensure that they can continue to deliver quality products to their customers while earning a profit. While you may not immediately think that farming would be an industry that could use solar panels, keep in mind that anything that uses electricity can be powered by the sun.

Travel

Even airports are seeing and understanding the need for renewable energy. John F. Kennedy International Airport was just awarded the contract to begin New York City’s biggest solar project by having rooftop solar panels on a building and parking lot. With the goal of reducing emissions by 80% no later than 2050, this is a great step in the right direction for JFK International Airport.

Manufacturing

A company called Heliogen uses mirrors to produce some major heat, up to 1,100 degrees which have the potential to replace fossil fuels. Cement factories, as well as steel or petrochemicals, need 1,100 degrees in order to produce their materials so regular solar panels would not have been an option for them. This is a revolutionary discovery by Heliogen and the project is now backed by Bill Gates. Because using these solar mirrors uses sunlight, it could save the manufacturers a lot of money compared to other energy sources.

what to look for during a building inspection

4 Things to Look for During a Building Inspection

Whether you need a building inspection because you are buying or selling a building, want to do some renovations, or want to add any kind of addition to the building, there are some things you should be aware of. An inspector is going to go through a list of items and determine whether they are acceptable enough to pass inspection or whether some improvements need to be made. Regardless of whether it is a home or commercial building, the following items are key to watch out for during a building inspection.

Foundation

Certainly the basis of any building is the foundation and having cracks in it can be extremely dangerous. This is especially the case if you have plans to add on to the building or renovate. Additionally, new codes can make fixing things like the foundation tremendously expensive.

Walls

If you are planning any type of renovation to your building you need to understand the walls that are load bearing before you start demolition. A load bearing wall can sometimes be taken down by putting up a beam if you so choose.

Cracks

One of the most obvious signs that can indicate issues are crack patterns. A structural engineer will study the crack patterns in the walls of your building and determine if they indicate problems. If the crack patterns show issues, the structural engineer can provide solutions to correct these issues in the form of CAD drawings. Don’t worry, they will explain everything so you understand.

Building Code Violations

Included with a structural assessment is often a property condition assessment. The engineer will determine the life left of mechanical systems, but more importantly they will be able to point out any building code violations. Many times building owners are unaware of such violations and only find out at the time of an insurance claim or other unforeseen incident.

Having a building inspection is a step in the right direction if you are preparing for future changes. Stay alert for the above-mentioned risks.

Flooring Methods to Reduce Vibrations

As a contractor, you probably already know about all the things that homeowners are concerned about. Flooring vibrations is one of the most common complaints you may hear. Homeowners tend to assume that when their house is being built or remodeled that the flooring will be perfect and have no issues. The problem with this issue is that it is subjective to each person. For some homeowners, they will be happy no matter what. For others, they will feel the vibrations immediately. There can be additions of furniture or other items in the home that may bring out the vibrations that may not have been noticed before.

In order to attempt to reduce or eliminate vibrations, there are several things you can do as a contractor. First, lateral bridging is an option but if it is not done perfectly then squeaking can occur down the road, rendering the work you did pointless. Some contractors may attempt to put the joists close together, but that actually does nothing for the vibrations in the floor. So you may better be prepared to deal with any homeowner complaints, here are the common live load deflections used in the United States.

Live load deflection limited to L/360

This is the minimum deflection that can be used based on the United States building codes. L/360 is structurally sound to be able to carry the load but means there will be a higher chance of floor vibrations being noticed. If you know for a fact that your homeowner will not care about this issue, you can use this live load deflection. It might be a good idea to discuss the possibility of floor vibrations with your customers.

Live load deflection limited to L/480

L/480 is 33% stiffer than L/360 so you would think that this would almost eliminate any potential issues. This is the most commonly used deflection for residential buildings and most contractors. Most likely, you are using this with your current jobs, and that is okay but there still is a chance of some flooring imperfections. Using joists that are 9½” and 11⅞” deep will certainly make issues more likely with an attached ceiling.

Live load deflection limited to L/960

The best deflection option out there for reducing floor vibrations is L/960 as it is 100% stiffer than L/480. Homeowners that will be very picky and notice any amount of floor vibration, or will specifically go looking for it, are great proponents for this option.

Customer satisfaction is of utmost importance to any business owner, but almost more so for contractors. You can build a homeowner the most beautiful house with quality craftsmanship and they still might find an issue if they have floor vibrations. Again, something as small as adding a kitchen island can cause these vibrations to be more noticeable to those who may not have noticed before. Using the stiffer live load deflection may help keep your customer satisfaction high.

Five Major Reasons Why Building Envelopes Fail, & Prevention Tips

At BE Structural, we see our fair share of building envelope failures. Think of a building envelope as the shell or skin of a structure. When exposed, the structure’s primary framing and building systems beneath it become vulnerable. A building envelope is therefore an essential component of the building’s infrastructure, creating a barrier in protecting it from external forces, primarily weather. Moreover, a building’s envelope regulates interior heat and moisture levels, while offering first impressions of its aesthetic appeal. A building envelope includes walls, doors, windows, foundations and roofs. So, why do building envelope failures happen?

Five Common Reasons Why Building Envelopes Fail

Design Flaws
The building envelope is a unique system requiring precise design-build engineering expertise to get it right. While facades may present desired aesthetic impressions, they may not be the best choices for intended uses. To err is human, architects may create designs that specify inappropriate materials.A common mistake occurs when building materials do not meet thermal movements in the area. Architects may forget Mother Nature always has the last say. Regardless of stone or masonry, temperature changes inevitably create cracks and loosen joints in structures. Design deficiencies also occur from water penetration, resistance and structural capacities. When water penetrates the building envelope, moisture becomes trapped, causing materials to warp. This also creates the perfect breeding ground for mold to grow—and introducing a new problem.
Construction Defects
Building envelopes fail due to construction defects or poor workmanship. This ultimately results in serviceability issues or worse—structural failures. For instance, subcontractors may minimize costs by reducing size, weight and the number of different components essential to maintain structural integrity. This is where BE Structural engineers mitigate defects by inspecting and assessing every required code is incorporated, to uphold the highest building standards to ensure the building’s lasting value.
Poor Workmanship
Poor workmanship arises during construction booms with many inexperienced, untrained and unsupervised personnel working on projects. Often, building envelope components are improperly installed, disregarding manufacturer specifications. Minimize this danger by putting the right people in the right job and providing a quality control program of installation, observation and inspection.
Natural Disasters
When a building envelope is exposed to major storms, wind-driven rains and hurricane-force winds, problems compound. This scenario includes structures that have been designed properly. A homeowner may have diligently installed siding and sub-systems correctly; but disasters happen, exceeding design expectations. Unexpected fluctuations in temperatures, hurricanes, and pounding rains damage even the best designed and installed features of any building. Tip: To lessen these weather effects, perform routine checks and regular maintenance repairs.Building envelopes are exposed to numerous elements, making them susceptible to damage even when “looking safe.” Be sure transitions and areas around doors and windows are checked regularly to avoid water from penetrating. Also remember that siding and other envelope components do not last forever; sometimes it makes sense to replace them, than spend lots of money later, on repairs. Be Structural is experienced in building envelope mitigation issues, and ready to offer cost-savings tips.
Costs of Repair Will Only Increase
Late maintenance and poor repairs inevitably contribute to problematic transitions and joint seals. Say a homeowner decides to remove a gutter expansion joint instead of repairing it. When it rains heavily, water will flow in all directions, with gutters receiving more water than they can handle. This example of poor maintenance adds to water intrusion, further weakening building envelopes.Seasoned property managers and homeowners know putting off repairs always costs more in the long run. Weather and natural deterioration of materials over time exact heavy tolls. Wintry conditions and freeze-thaw cycles severely impact building exteriors, leading to cracks in masonry, split caulked joints and deteriorating mortar joints. Roofing systems weaken and degrade with snow piling on and melting off. If a building’s degradation is not monitored and maintained, it snowballs to unsafe living conditions.In addition, expenses to repair and fix degraded conditions are more exorbitant. However, being proactive and conducting routine inspection, repairs and maintenance, will protect property owners from unnecessary emergencies. BE Structural engineers are happy to inspect and detect problem areas before water and moisture cause extensive and expensive damage to properties.

Tips for Mitigating Envelope Failures

How to mitigate, even prevent, building envelope failures? At BE Structural,
We start with a properly designed building envelope engineered to follow all applicable codes and standards.
Second, we select appropriate building materials.
Third, prioritizing these first two critical functional steps means incorporating them into the early stages of design-build, to prevent future failures and serviceability issues. Every building component must be well-maintained for the building’s weatherproofing and structural soundness.
Fourth, we recommend consistently inspecting and maintaining the building envelope.
BE Structural uses thermal imagers to detect moisture intrusion and building envelope failures.

If a building is well-maintained and kept safe, current tenants and potential buyers will continue to enjoy living and working there. Tenants spared from leaks are happy tenants. That’s why BE Structural believes an ounce of prevention saves pounds of costly cures.

The Benefits of Residential Solar and Whether It’s Right for You

Written by Bret Engle

Residential solar continues to grow in popularity. This is largely due to the fact that solar power, as well as other types of renewable energy, is quickly becoming more affordable for households throughout the United States. What’s more, it’s also becoming increasingly abundant. This article will discuss the advantages of using residential solar, as well as which roof types are ideal for panels and how the installation process works.

THE BENEFITS

Let’s take a look at some of the biggest advantages to using solar power:

It provides you with energy independence.

One of the most appealing aspects of solar power is that it provides freedom and control of your electricity. Many components of the US power grid are outdated, and it has resulted in increased outages over the last decade-plus. By installing solar panels along with a home battery unit, households can have enough electricity to power their home day and night — no matter what is going on with the grid in their neighborhood.

It’s clean and renewable.

Environmentally speaking, solar energy is ideal because it’s completely clean and renewable. The need for coal, natural gas, and oil is significantly reduced, which helps to mitigate the harmful impact these fossil fuels have on the air, water, and soil. No pollution is caused by solar power, and as more people use it, it can help to protect the earth from global warming.

It now makes sense financially.

Another appealing part of solar energy is that it’s beginning to make more sense for the average American household to invest in it. Residential solar costs have dropped more than 70 percent over the last 10 years, and home battery units have become more affordable as well. Plus, solar panels are low-maintenance, they can help you save on your monthly utility bill, they come with tax benefits, and they can raise your home’s value.

If you need help getting the funds to install solar panels, there are financing options available. According to Redfin, if you qualify for the FHA’s Energy Efficient Mortgage program, it will incorporate the costs of installing panels into your mortgage. The program also provides assistance for other home modifications that benefit the environment.

THE BEST ROOF TYPES

Most residential solar panels are mounted on the roof of a home because it takes up the least amount of space. While pretty much any type of roof can be used for panels — given that the roof is in good condition — there are a few kinds that work best. For instance, asphalt shingles are strong and durable, and it’s fairly easy to mount panels on this type of roof.

While tile roofs typically require brackets to be installed along with the solar panels, installation should still be pretty simple. These kinds of roofs come at a higher price, but they ultimately require little maintenance and typically last longer than some other types. Like tile roofs, metal roofs are long-lasting and low-maintenance. They also make for the fastest solar panel installation, and that can save you some money on labor.

INSTALLATION

Installing residential solar is a process. Typically, an engineer will come to evaluate your home to ensure that it’s compatible with a solar system; the engineer will also make sure the roof is in good condition. Then, there’s a lot of paperwork, though most of it is handled by the installer. The paperwork includes applying for solar incentives and permits, and it’s important to have a basic understanding of each document.

After that, you’ll be ready to consult with the installer to choose and order the equipment (e.g., solar panels, inverters, etc.), and then schedule the installation. This process includes things such as roof preparation, electrical wiring, attaching racking to the roof, putting the panels on, and connecting the inverters. You can expect the entire process to take about one to three days, depending on the type of roof and the size of the system.

Changing to solar energy comes with a lot of benefits. However, be sure to consider what kind of roof you have, and make sure you’re prepared for the installation process. Most importantly, continue to educate yourself on residential solar so that you can make an informed decision about whether it’s right for you.

Why do we grieve for a collapsed building?

Written by Dana Pezzuti, BE Structural, PC

I’ve read a few pieces that try to put it into words. Since the fire that claimed much of the structure of Notre Dame, it seems social media is buzzing with opinions on why we shouldn’t grieve for this building and better uses of our time and energy.

After all, what is a building but a bunch of materials stacked, framed and bolted together?

As an individual working within the architecture/engineering/construction industry, my thoughts are a bit different.

For building designers, consulting engineers, architects, masons and carpenters- a building is so much more than a bunch of inanimate objects. It is a place of shelter, a place of congregation- carefully thought out, tested and engineered. It is a work of art that is both beautiful and functional.

Every year, every decade, every century it endures it is a testament to the expertise, craftsmanship and the newly discovered technology that was used to build it. Every time a war, plague or storm fail to destroy it-the more the structure becomes a benchmark of human progress.

There were no building codes in place when the cathedral of Notre Dame was constructed. Let’s remember that. The engineering, science and math it took to ensure stability is mind boggling considering very few people understood the principles that we embrace today.

There were not building inspectors handing out citations for shoddy work. No stamped drawings carefully reviewed by a structural engineer and permitted. There were only human beings putting their faith in one another and inspiring others to join their cause. All of our modern day safety measures came about hundreds of years later and even in 2019, buildings fail and bridges collapse-And we mourn the loss of human life.

So when a 700 year old cathedral built in the Dark Age’s burns, we do grieve a little bit. Just as we grieve if our own home or our neighbor’s home is destroyed. Not for the loss of bricks and stone but for the people who came together, the memories they made and the children they raised under its common roof.

In the case of Notre Dame, we mourn for the carpenter who worked on the building 700 years ago. We mourn for the architects and masons that came together to create a functional masterpiece so long ago. Those who jumped at the chance to be a part of human advancement without question. Those who poured their heart and soul into its creation but never saw the final result. That is why we mourn the loss of this building.

The Different Ways a Steel Structure Can Fail

The job of every structural engineer is to ensure any given building is safe and structurally sound. This can occur during the initial design of a building or during the inspection of an existing building. When it comes to steel structures, it’s hard to imagine them failing due to the strength of the building materials themselves. However, there are several different ways steel structures can fail, and most of them can be prevented with the help of great structural engineering practices. Here are the main ways steel structures can fail.

Insufficient Strength With Connections

Almost every time you hear about a steel structure failing, it’s because of a connection issue. A structural engineer has to put in an incredible amount of thought and detail when designing the joints and connections to ensure they are strong enough. Calculating the strength of joints and connections is a tedious process, and it’s important for the structural engineer and the construction professionals to be on the same page. Any type of miscommunication in the type of bolt or other materials to use can lead to insufficient strength and possible failure.

Tension Failures

Another possible failure in steel structures is putting too much tension on any given member. It takes a significant amount of tension to create this type of failure, and most of the time it only occurs when the structural engineer makes a mistake in the design process. Tension failures are widely known as the most dangerous type of failure, so every structural engineer places a high level of importance on it in the design phase.

Too Much Weight On Beams

Beams can fail in a steel structure as well. It’s fairly simple to figure out when this type of failure will occur, since it happens when the weight on the beams exceed the weight limit they can handle. Lateral torsional buckling is the main concern for every structural engineering company, since it involves predicting where the most significant amount of weight will be placed on the beam. The strongest point of the beam is in the center of it, so buckling could occur and lead to beam failure if the weight on either end of the beam is too much for it to handle.

BE Structural is a team of structural engineering professionals that has an extensive portfolio of construction and engineering projects. Whether a steel structure undergoes minor local buckling or has experienced significant structural failure, we have an expert ready to evaluate the situation and provide the best solutions. No project is too large, small or complex for our structural engineering professionals, so don’t hesitate to contact us at any time when you need us.

The Problems the Millennium Tower is Facing in San Francisco

When the $550 million construction for the Millennium Tower in San Francisco was announced, there were no shortage of buyers ready to spend millions of dollars to purchase living space. However, less than a decade later, those buyers have lost significant value in their investment due to various unforeseen issues to the tower.

Various structural engineering companies, as well as geotechnical companies, are evaluating the building daily to analyze the cracks, sinking and leaning that are clearly present. While the problems with the Millennium Tower are evident, there are still plenty of questions surrounding the safety of it, who is responsible for these issues and what structural engineering experts are going to do about it.

How Safe Is The Building Today?

The good news is the last time a structural engineer evaluated the building, it was deemed to be safe to live in, even if an earthquake occurred. However, the fact that the sinking of the building doesn’t appear to be slowing down anytime soon can’t be ignored. Structural engineering experts estimate the building will continue sinking between 1.5” to 2” every year, which simply means action needs to be taken now to prevent a potential disaster in the ensuing years.

Where The Blame Lies

Initial inspections indicate the main problem being in the foundation of the Millennium Tower. The soil it’s built on consists of sand, clay and mud, and the foundation does not even extend far enough down to reach solid bedrock. There’s some controversy surrounding the City of San Francisco and why they allowed the construction and design team to not anchor the foundation low enough to reach the bedrock.

Another area of blame has to do with the construction of the transit center that was newly built adjacent to the tower. The construction company responsible for building the Millennium Tower is suggesting the company that constructed the transit center pumped too much groundwater during their project, which caused the sand under the Millennium Tower to compress, and has resulted in the sinking.

Possible Solutions To Fix The Millennium Tower

As structural engineering experts continue to discover the reasons why the Millennium Tower is experiencing these problems, they are also developing short-term and long-term solutions. One of the possible solutions includes removing some of the top floors in order to reduce the weight of the tower. The most discussed solution for the long-term is to bore micro piles on the side of the building that’s sinking in order to eventually anchor it to the bedrock underneath. Once this occurs, the high side of the building must sink to the level of the low side before the anchoring can occur. This proposed solution could take up to five years and cost several hundred million dollars, but it is the most viable solution for the long-term, as analyzed by structural engineering experts.

At BE Structural, we always monitor these types of stories and are actually involved in many of them. We are a structural engineering company with experts coming from many different backgrounds and having various levels of experience. If you have any specific questions about the problems the Millennium Tower in San Francisco is facing, or have a need for a structural engineer, contact us today.

What Qualities Should Your Structural Engineer Have?

When you have a new construction project or are doing major renovation work, one of the first experts to call is a structural engineer. However, just like not all structural engineering companies are created equally, neither are individual structural engineers. The best ones will work with the architects, designers and other contractors you hire in order to ensure everyone is on the same page with the same vision for the project. Before you hire a structural engineer for your project, make sure they possess these qualities.

Creativity

No two buildings are exactly alike, so your structural engineer should use their knowledge, skills and expertise to design the safest and strongest building for your particular project. This includes evaluating the weather and climate and using building materials that will withstand the harshest elements. Structural engineers have to be creative in order to build a safe structure, while still fulfilling the needs and vision of the homeowner or property owner.

Extreme Attention To Detail

There are plenty of obvious reasons why a structural engineer has to be extremely detailed in the work they do. One seemingly minor mistake could lead to a fatal flaw in the design of the building. And the structural engineer needs to follow through with the other contractors who are actually building the structure to ensure everyone is on the same page and there’s a complete understanding of their thought process.

Innovative Strategic Thinking

With the technology available to every structural engineering company today, there’s no excuse for not using innovative technology to help design a building. The challenge every structural engineer faces is being able to satisfy the needs and desires of the individuals, while also adhering to safety regulations, sustainability practices and more. It requires innovative and strategic thinking to be completely well-rounded, and taking the time to find a structural engineer who possesses these qualities is well worth the effort.

Problem Solving

Problems will always arise in any project, no matter how large or small it is. Whether it’s external factors like the weather, or other unique challenges that aren’t evident immediately, a good structural engineer must be able to think quickly. The best structural engineering professionals will be able to identify problems before they occur and plan on a solution, but sometimes it’s not possible. In either situation, coming up with the best solutions possible is an important quality for structural engineers to have.

At BE Structural, we have a unique mix of structural engineering professionals that work together every day. Each of our structural engineers are well-rounded when it comes to their education, experience and background, and we are constantly in collaboration with one another to enhance our skills. We strive to be your go-to resource for any structural engineering needs, so don’t hesitate to contact us if we can be of service to you.

5 Common Structural Issues in Industrial Buildings

The manufacturing industry is arguably the most important industry in the United States. While it’s important to keep manufacturing machinery and equipment maintained in order to keep production going, it’s equally as important to maintain the industrial buildings where the work is done. If the integrity and safety of an industrial building is compromised, it could lead to the manufacturing plant being shut down until a structural engineer can come in for an evaluation. While significant events like this are not likely with preventative maintenance practices, here are five of the most common structural issues in industrial buildings seen by structural engineering companies.

Interior and Exterior Wall Damage

Both interior and exterior walls will eventually experience some damage in industrial buildings. With forklifts, operations vehicles and other heavy equipment constantly being used, it’s inevitable for some damage to occur. The main thing to do is have a structural engineer evaluate the damage and have it repaired right away if necessary. Most of the damage is cosmetic, but it’s always better to be cautious.

Damage To Columns

Depending on how severe the damage is, a damaged column could be very dangerous from a structural standpoint. It seems like every column in an industrial building is in the way for forklift operators, which means they will get dinged up occasionally. But as long as the damage is minor and doesn’t have a structural impact, then operations can continue as normal.

Inadequate Framing

Many industrial buildings are very old. During the original design of the building, the framing was likely designed to support a certain amount of stress. When structural engineering experts see an issue with framing in an industrial building, most of the time it’s because too much stress was put on it. Because of this, it’s important for managers to have the framing inspected whenever additional equipment is added that could increase the stress on it.

Poor Roof Draining System

When water stays pooled on a roof without draining properly, there’s a wide range of issues that could occur. Any structural engineering company will inspect the roof of an industrial building to ensure gutters are working properly and the best systems are in place to properly drain water from the roof.

Neglected Maintenance Practices

Accidents will happen in an industrial building with so many moving parts at any given time. However, any structural engineer will tell you major issues can be prevented by performing routine maintenance practices. These could include ensuring roof drainage systems are functioning, no rust is present on steel components, all seals and connections are in good shape and more. If there are any issues that need the expertise of a structural engineer, don’t hesitate in contacting one.

BE Structural is here to ensure all industrial buildings are in good working order so manufacturing processes can continue without interruption. Production is critical for every manufacturing plant, but so is safety. As a structural engineering company, we will evaluate every component of your building, identify any potential issues and promptly fix them.

3 Ways a Structural Engineer Can Help With Your Custom Home

When a custom home is in the works of being built, there’s an entire team of people you need to look at hiring. These people include architects, interior and exterior designers, engineers, contractors for general work and many more. Most people don’t think about contacting structural engineering companies first, but the truth is finding a good structural engineer should be a top priority. No matter how good a home looks on the outside, it’s only as good as the structural engineer who designed the plans from the foundation all the way to the top of the chimney. Here are the main ways a structural engineer is important when you’re looking to build a custom home.

Structural Safety

Every structural engineering company prioritizes safety in all aspects of the work they do. When evaluating the location of a custom home, a structural engineer will look at factors like the soil, the climate in the area, what major weather events typically occur, the seismic activity and more. Sometimes it’s simply not safe to build a home with the exact orientation the homeowner wants, which is exactly why it’s important to take the advice of structural engineering experts.

Use The Right Building Materials

While safety is the first priority when building any custom home, structural engineers also want to bring a homeowner’s vision to life as much as possible. This can include wood framing, bamboo, masonry, steel or any other materials. Many times a structural engineer will get an idea of the vision the homeowner has and then go to work designing the home based on that. If it’s simply not possible or safe to build it exactly like the homeowner desires, then they will inform them accordingly. There are many different factors that go into the building materials used for any custom home, and the best structural engineers will still make the custom home look as close to the homeowner’s vision as possible.

Efficient Designing

Most people don’t think about contacting a structural engineer when designing their home. This is typically done by an architect. However, structural engineers put together plans for the design that takes into consideration the foundation, roof, framing and overall structural integrity to be able to support the desired designs. Architects and other contractors rely on structural engineers for this information, which is why they are typically the first experts needed when designing a custom home.

BE Structural has helped build hundreds of custom homes over the years. Our unique team is comprised of experts with various backgrounds and different levels of experience, so no project is too large, too small or too complex for us. In fact, we enjoy taking on complex custom home designs since it challenges our skills.

How Can Structural Engineers Build in a More Sustainable Way?

Waste is a common problem among many different industries worldwide, and the construction industry is one of the leaders in producing waste. However, with society becoming more aware and conscious of the materials they are using and how to properly dispose of them, structural engineering companies are also doing the same. This involves altering practices and procedures, disposing of waste differently, eliminating harmful compounds when using building materials and more. All of these combine to make more sustainable buildings and protect our planet as well. Here’s how structural engineering companies are building more sustainably today.

Incorporate Zero Waste Practices

Zero waste practices mean using products and materials that can be reused instead of discarded when they are no longer needed. A common example of this is when a structural engineer designs a building by using bolts for connections rather than welds. The bolts can be reused when the building gets remodeled or demolished, but anything welded will simply have to go to the landfill in most cases.

Eliminate Volatile Organic Compounds

Breathing in volatile organic compounds can be dangerous when ingested in large amounts. Building materials have traditionally contained these volatile organic compounds, but structural engineering companies are now being more conscious about the products and materials they use to ensure they don’t include them. Not only are these materials better for the environment, they also protect the construction workers who come in close contact with them.

Compost Waste Instead of Dumping in The Landfill

It’s easy for a structural engineer to say they’ll throw any waste in the landfill. However, many structural engineering companies today are composting some of their organic waste on the actual construction site when possible. This reduces the amount of waste in the landfills and also eliminates having to pollute the air with trucks driving to and from the landfills.

A Conscious Effort Will Go A Long Way

Being conscious of reducing waste and building in a more sustainable way will pay dividends for our environment in the future. The job of a structural engineer is to ensure a new project or a renovation project is designed in a safe manner, and also in a sustainable manner. Of course, it’s not always possible to apply all of these practices in every single construction product, but simply having sustainability in the back of the mind is a positive step forward for the environment.

BE Structural uses sustainable practices whenever possible. As a structural engineering company, it’s our job to ensure every building is designed and constructed safely. However, we are also very conscious of the environment we live in and the safety of the air we breathe. Quality does not have to be sacrificed when incorporating sustainable practices, so contact us today to see how we include these practices every day.

Will Building with Timber Ever Become the Norm?

A structural engineer is tasked with researching and analyzing the different materials that can be used to design and construct any given building. Some areas may need a steel or concrete building due to its climate or significant weather events, while others may be suitable for timber materials. There’s no doubting the possibility of using timber for nearly every project. However, the question many structural engineering experts have is whether building with timber will become the norm across the industry. Here’s a deeper look at this possibility.

Location Is A Major Factor

Since wood is weaker than steel or concrete, the location of a wood building is a critical component to think about. The reality is wood can be used in any location, but at what cost? Larger and thicker materials will need to be used in areas that experience significant weather events, which will increase the cost of the building and also potentially reduce the amount of living or working space due to the size of the materials. So in most of these situations, building with wood can be less economical in many ways.

Problems With Using Timber in Construction

In addition to the potential higher cost of using timber, structural engineering professionals also bring to light other possible problems. Shrinkage, creep, elastic deformation and similar issues all play a role in why a structural engineer may opt against using timber. The good news is most of the possible problems with using timber can be alleviated by combining other stronger materials with it, especially when you’re building taller structures.

Timber Combined With Other Materials is More Effective

Many structural engineering experts will suggest a hybrid construction for certain projects. Using steel or concrete for the structural aspects, and incorporating wood for columns and other aesthetic purposes, are typically the most effective strategies from structural and cost-effective standpoints. Every construction project is different, so each structural engineering company has to look at the unique aspects of the project to determine the sustainability of the materials used. Hybrid designs are quickly becoming the norm, so the likelihood of complete timber designs becoming standard is very low.

BE Structural is a team of structural engineering professionals dedicated to designing and constructing the most sustainable buildings for both commercial and residential purposes.

Whether it’s by incorporating more energy efficient materials or boosting productivity and efficient processes in the construction process, technology is typically beneficial for a structural engineer. Here are some of the main technological advancements used in structural engineering today.

The Use of Drones in Construction

Drones are used by structural engineering professionals to take aerial photos of a construction site, monitor activities and survey areas where accessibility is limited. The photos taken by drones have high resolution and can be used to take measurements, create digital models and much more. Plus, the use of drones is much safer for a structural engineer when it comes to surveying tall areas like roofs or bridges.

3D Printing

3D printing has significantly developed over the last several years. And in the coming years, it is expected to become an even more valuable resource for structural engineering professionals. Using 3D printing allows experts to create more accurate design details, as well as more customization for projects. 3D printing is typically used most effectively for commercial properties or in large-scale residential complexes.

Data Analysis Tools

There is a lot of data collected by a structural engineer before, during and after any construction project. Analyzing this substantial amount of data is important, but sometimes isn’t possible due to the sheer quantity. Data analysis tools continue to develop today to help structural engineering experts analyze the data collected most effectively. The technology, software and cloud solutions available today help gather significant amounts of data quickly and make it easily accessible to all members of the construction team to promote efficiency, accuracy and more.

Augmented and Virtual Reality

Augmented reality tools are typically used at the beginning stages of the design process. One of the main uses for these tools is to visualize how a particular construction design will fit in any given area. This allows structural engineers to identify any potential errors or complications and can fix them before the project even begins.

Virtual reality technology includes scanners and drones to collect information. This technology is helpful not only in the design process, but also to allow project managers to constantly monitor the progress of the project without having to be physically present. Accuracy and efficiency are the two main benefits of virtual reality tools and are increasing in importance every day.

BE Structural stays on top of the latest technological trends to ensure the most valuable resources are being used at all times.

What Materials are used in Sustainable Structural Engineering?

As people and companies become more conscious about energy consumption, perspectives in structural engineering are changing as well. It’s easy to upgrade appliances or install energy efficient equipment into new home designs, but those can get costly very quickly. The good news is there are sustainable materials used around the world today that are safe for the environment and can make very nice homes. Here are some of the materials a structural engineer will consider using when building a sustainable home.

Earth Bags

Earth bags are made of polypropylene material and are filled with soil and other inorganic materials. They are designed to hold up better than concrete or bricks, since the bags will not crack or be easily damaged during events like an earthquake. Earth bags are used prominently today in developing countries to build sustainable homes.

Earth Blocks

A structural engineering company will sometimes use earth blocks instead of bricks to create a more sustainable design. The earth blocks consist of a mix of clay, rubble and subsoil and are compressed at a very high pressure. In fact, earth blocks are actually stronger than concrete blocks or bricks, but only use a very small amount of cement. By using a small amount of cement, earth blocks are sustainable and reduce the amount of carbon emissions released into the atmosphere.

Retrofitting

Seismic retrofitting can be used to rebuild, repair or strengthen structures in general. After a structural engineer evaluates a building, they can perform actions such as repairing any damage, increasing shear wall density, strengthening ground conditions and more. Seismic retrofitting has helped strengthen thousands of buildings worldwide, especially in developing countries that experience earthquakes and other natural disasters.

Trombe Walls

Trombe walls are used in sustainable structural engineering to create more of a passive solar design in homes. The outside of the walls are made with plastic or glass panes, and the inside of the walls have a higher heat capacity. What makes these walls sustainable and energy efficient is the fact that the external wall will absorb the daytime heat and transfer the heat into the home when needed. Trombe walls are used effectively in areas where sunlight is present the majority of the time and people want to create a more sustainable and energy efficient design for their structure.

BE Structural is a team of experts with a wide range of experience. Our structural engineering company has worked with sustainable materials in different construction projects, and we always practice innovative thinking. It’s important to work with a qualified structural engineering professional if you’re considering using sustainable materials for your next construction project, so contact us to see how we can help you.

The Importance of Structural Engineering When Designing a Passive Solar Home

A passive solar home is unique due to the fact that essentially every element of the home is used to collect energy and distribute it evenly throughout the home. This includes the floors, roof, walls and even the windows. The only way these passive solar homes can be effective is by the careful and thorough design by a structural engineer. Everything from the area you build the home at, the materials, the base structure and more all combine to make a passive solar home useful. Here are some things to consider about structural engineering and passive solar homes.

Factors To Consider For Passive Solar Homes

The sun doesn’t have to shine around the clock in order for passive solar homes to work, but these factors are essential:

Location on the land you’re building on. By building the home on the northern side of the lot, the southern end of the home will have the clearest possible view of the sun.
The structure itself. Your structural engineer will tediously design the windows and walls to ensure they are exposed to as much sunlight as possible. Some windows should allow sunlight in, while other surfaces on the structure should absorb the heat to store and use at a later time.
Design materials. The most common materials used in passive solar homes include brick, tile, stone and concrete. These are the best thermal mass materials since they absorb and store heat from both the inside and the outside to be used at the appropriate times of the year.

Challenges When Designing Passive Solar Homes

From a structural engineering perspective, the main challenges of designing a passive solar home include ensuring the home is air tight and is structurally stable. Most passive solar homes will have a larger ratio of windows on the southern side of the building, which means there will be fewer structural shear walls on that side. In order to prevent damage to the windows because of the stress placed on them, trimming beams are usually specially designed to give them additional strength.

Collaboration And Comprehensive Analysis is Essential

A structural engineer must work closely with the design team and any other contractors who are working on a passive solar home. Since there are so many different nuances and various components to these homes, every detail is critical. Every good structural engineering company can take the lead in ensuring the home is designed and constructed safely and will be as effective as possible.
