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.

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.

5 Key Components to Help Identify a Building Envelope Failure

By the time a building envelope fails, a thorough investigation has to take place to determine the exact cause. There are many reasons why this failure can occur on any given building, but identifying the issue takes some experience. With a building envelope inspection by a professional, most issues can be identified and corrected before major damage occurs. However, there are some signs you can look out for as well to help identify the potential for failure.

Air Leaks

If air leaks out of a building through windows, doors or attics, potential problems could arise. There could also be air leaks in a building you aren’t even aware of until your energy bill skyrockets. Air leaks are problematic because they can lead to condensation if the humidity from outside is being pulled inside.

Water Penetration Vulnerabilities

Sometimes poor design or construction of a building can lead to water penetration vulnerabilities over time. During the course of building envelope engineering, a significant amount of sealant is used to prevent water penetration, but even the tiniest oversight can cause big problems.

Insulation Breakdowns

Insulation in a building is more functional than simply keeping you warm in the winter and cool in the summer. It also acts as a barrier to prevent outdoor elements from getting into the home and causing problems with the building envelope. Without insulation, extreme temperature difference indoors compared to outdoors can create moisture and lead to building envelope failure.

Differential Movement

Thermal expansion of concrete, masonry or other building materials can lead to differential movement. This is one of the most difficult features for the average person to identify, since the changes are so subtle. Too much differential movement can cause the structure to fail in different ways. Getting a building envelope inspection frequently is sometimes the only way to identify and correct this issue.

Condensation

Condensation that builds up on windows during certain times of the year is generally harmless when it’s wiped away. However, when condensation builds up in between wall cavities, it could eventually cause building envelope failure. This type of condensation is more difficult to identify, and when you do, most of the time the majority of the damage has already been done.

BE Structural has a team of building envelope engineering experts to help you identify potential failures in your structure. If you have the ability to identify any of these signs on your own, then don’t hesitate to give us a call to schedule an inspection. It’s always a good idea to schedule regular inspections anyway to prevent building envelope failure from occurring in the first place.

Is Your Building Envelope Failure Because of Workmanship Errors?

Just like there are many reasons why a building envelope may fail, there are many workmanship errors that can cause the failure to start. Following a building envelope inspection, most of the time the issue discovered boils down to a workmanship error during the design, construction or the installation of certain components of the home. Most building envelope failures are the result of water intrusion, and many times the expertise of building envelope construction is needed in order to identify the issues. Here’s how you can tell whether your building envelope failed because of a workmanship error.

Most Common Workmanship Errors

Since water intrusion is generally the most common reason why building envelopes fail, building envelope consultants typically identify workmanship errors as being the cause. Most of these errors deal with the improper installation or improper sealing of water diverters and end dams.

Not all workmanship errors derive from the installation process, however. Sometimes poor design and planning practices can also lead to issues with the building envelope. Sometimes it takes more than a simple building envelope inspection to determine the actual root cause of the error.

Can Workmanship Errors Be Prevented?

Since there are many different people who work on the design and construction of any given building, a workmanship error is inevitable. However, sometimes these errors aren’t a result of negligence. Rather, it could be the installation professional did not have access to the original design plan or was not instructed correctly. In order for every single workmanship error to be prevented, each person involved with the process of constructing a building from start to finish must be on the same page and have a clear understanding of the installation requirements.

Building Envelope Inspections Can Reveal Facts

You will never truly know where an error originated from unless you have a thorough building envelope inspection conducted. Whether it’s a residential or commercial building, these inspections can actually begin the investigation process of determining who is at fault for the building envelope failure. Many times it’s discovered that the person who performed the installation actually isn’t at fault at all.

BE Structural has a team of building envelope consultants to thoroughly analyze and evaluate the reasons why a particular building envelope may have failed. The extensive process of the inspection is detailed and is the only way to truly identify whether the failure was caused by workmanship errors or any other reason. To learn more about the process, don’t hesitate to contact us at any time.

Forensic engineering

Monitoring the Effects of Commercial Construction and Demolition Vibrations

With the close proximity of buildings in urban areas today, commercial construction and demolition can create significant risks to existing buildings. However, with old buildings being demolished and new ones being built every day around the world, we have to adapt and ensure vibration damage is minimized. Monitoring and analyzing the potential and current impacts of construction and demolition projects are some of the most important roles for forensic engineering experts. Here’s how the technology works and why it’s so important.

What Exactly is Vibration Monitoring?

Throughout the vibration monitoring process, seismographic equipment records ground movement created by demolition and construction activity. Every structure has a vibration threshold, so when a sensor detects a vibration above the threshold, an alert is signaled to the construction crew working on the project. These real-time alerts can actually save a building envelope from being partially damaged or, in the worst-case scenario, completely destroyed.

Nearby Structures Could Be Affected by Demolitions

Every structure can withstand different levels of vibrations. And just because a vibration can be felt in a nearby building, it doesn’t necessarily mean any amount of damage has been done. Many business owners have concerns about the structural glass design of their building, but the reality is it’s measured just like any building envelope. Experts take the building material into consideration when analyzing construction and demolition vibrations, and special care is taken if a particular building has a low tolerance for structural vibrations.

The Role of Forensic Engineering

Forensic engineering plays a large role in determining how safe it is to proceed with a construction or demolition project. It starts by conducting pre-project surveys of nearby structures to determine whether there is any existing damage and to analyze the vibration tolerance of the building. Even the smallest cracks in a foundation can increase the chances of vibration damage.

Once the construction or demolition project is complete, forensic engineers survey the surrounding structures again to compare the reports. They will analyze the data from the vibration monitoring devices and determine whether any potential damage was caused by vibrations from the project. These detailed records are critical when potentially filing a claim on damage to a building.

At BE Structural, we have a team of forensic engineering experts with years of experience in monitoring and analyzing construction and demolition projects. Our role is to ensure the safety of every nearby structure that could be affected by vibrations. For more information about what we do and how we can help with your construction or demolition-related projects, don’t hesitate to contact us at any time.

Can Structural Failures Be Prevented?

It seems like you hear about a structural failure every day somewhere around the world. While many of these failures occur as a result of a natural disaster, many of them could have been prevented with quality building envelope engineering. Building a new structure requires many different levels of analysis before the building process even begins. But missing just a single step could end up with forensic engineering services being at your property to pinpoint why the structure failed. Here are some ways structural failures can be prevented.

Importance of Soil Testing

The soil you decide to build a structure on is just as important as the building materials themselves. Many contractors will rely on the property owner to hire an outside service to do a soils report, and won’t even ask about it. Getting a soil analysis requires an upfront cost, but can prevent a failed structure in the long run. The best building envelope engineering companies will require a soils report before building the structure, just to ensure the stability of it for years to come.

Impact of Geotechnical Engineering and Structural Engineering

Geotechnical engineers focus on the rock and soil underneath the structure. Structural engineers focus on the actual building itself. While both analyze completely different aspects, they work together to ensure stable structures. When facade engineering consultants believe the foundation of a structure is unstable, they will many times call on geotechnical engineers to analyze the soil first. But when the two work together before a structure is even built, then structural failures can be prevented more often than not.

Experts Can Prevent Structural Failures

No one wants to have forensic engineering services out on their property to analyze a structural failure. Instead, rely on the experts to ensure this type of building failure won’t happen in the first place. Building a new structure is not a time to cut corners to save costs. Too many people underestimate the importance of analyzing all aspects of a building structure and the land it sits on, which is why we are seeing so many structural failures worldwide.

At BE Structural, our structural engineers can help you analyze your building materials and foundation to ensure stability. Our experienced facade engineering consultants will make suggestions based on thorough analysis so you can better prevent a structural failure from occurring. Be sure to contact us to learn more about how we can help you prevent structural failures.

What to Know About the 40 Year Building Safety Inspection Program

The 40 Year Building Safety Inspection Program is a fancy way of saying your building needs to get a commercial property condition assessment when it is 40 years old. This program has been in effect for more than a decade, and applies to any commercial buildings, including schools, in Broward and Miami-Dade county. Property managers or business owners must consult with structural engineers to have a proper inspection completed at 40 years and then once every 10 years afterward. These inspections are designed to keep people safer from possible building failure during extreme weather conditions and other scenarios.

Purpose of the 40 Year Building Safety Inspection Program

The main purpose of the program is to ensure the building is safe from a structural and electrical standpoint. Many structural engineers spend the majority of their time conducting inspections on older buildings, and they are required to prepare a report of their findings. Buildings older than 40 years old may not be strong enough to withstand hurricane force winds and other weather phenomenons, so the purpose of the inspection program is to ensure the building is as safe as possible to prevent injury or death.

All 40 Year Old Buildings Must Undergo an Inspection

In Broward and Miami-Dade county, there are very few exceptions where a building would not have to have a commercial property condition assessment. Even if you haven’t used a particular building in years, the property owner is still responsible for participating in the program. The first step a property owner must take is to look for the best structural engineers. These engineers can help you through the process to ensure compliance from start to finish.

Timeline for the Inspection

When it comes time for a 40-year property assessment for commercial buildings in Broward and Miami-Dade county, the property owner will receive a notice that an inspection is due. At that point, the property owner will have 90 days to find a structural engineer to complete an inspection of the building and submit a report to either the city or the county. The report will indicate what parts of the building (if any) need to be repaired or replaced. The property owner will have another 180 days to complete the necessary repair work. The structural engineer will then prepare another report following the completed repairs.

It’s important to find only the  best Broward and Miami-Dade county structural engineers to complete your 40 Year Building Safety Inspection. Be sure to contact us to get in touch with one of our experienced professionals to help you complete your inspection.

The Ins and Outs of Building Envelope Engineering

building envelope engineeringDepending on how much you know about the engineering industry, you may or may not have heard of building envelope engineering. However, it is a very important part of the engineering process, and involves the three basic components of a structure: the foundation, the walls and the roofing. If these parts of the building are not structurally sound, then the building itself is unstable and not fit for human use. It turns out that all three of these building components have one uniform purpose. The purpose of this article is to educate you on what they are, and how they’re a significant part of what structural engineers have to think about when they plan out an engineering project.
