The increasing popularity of green roofs in U.S. urban environments has structural engineers, developers and architects looking up these days. Over the past 10-15 years, green roofs have begun to appeal to building owners in U.S. cities. This trend only promises to increase as property owners see this roof as a way to embrace environmentalism. Although trending now in the United States, living roofs are far from a new concept. They have been in use around the world, in one form or another, for hundreds of years with the earliest versions in Iceland. Europe saw its first modern green roof in the 1960’s; when Germany discovered that vegetation on a roof could help with storm water management. As this trend continues, the many benefits of a green roof are becoming even more apparent. Other than the obvious aesthetic benefit, installing a green roof offers a multitude of other advantages. By growing plants on a building’s roof top, owners are effectively replacing the vegetated footprint that was destroyed or will be destroyed during construction. However, the advantages don’t stop there. Green roofs hold numerous environmental benefits. The EPA has reported that vegetated roofs help to reduce water runoff by as much as 75%. While they also work to filter whatever water runoff does occur. Green roofs improve air quality in the surrounding environment. Rooftop plants will naturally filter noxious gases and help to rid the air of pollutants. The plant life on a green roof can extend the roof’s life by protecting it from UV rays and other natural elements that wreak havoc on roofing materials. Vegetated roofs have proven to reduce energy costs substantially. They achieve this by acting as natural insulators against the cold and heat, and thus improve a building’s energy efficiency. Besides the above-mentioned benefits, green roofs offer an aesthetically pleasing and healthy environment to work and live. In an urban environment where green space is scarce or at a premium, a living roof can offer anyone a place to relax and enjoy nature. Living roofs can be used as recreational spaces such as playgrounds or community gardens. These green havens increase biodiversity by providing vital habitats for species of plants and animals. The green roof atop the Jacob Javits Convention Center in New York City is clear proof of the practical benefits of a living roof. This massive convention center has a six-block footprint and before 2014, its roof was completely barren. It is now the largest green roof in New York City. [Alan Steel, the CEO of the Javits Center reports that this eco-friendly roof boasts 300,000 bees, 25 different species of birds, a reduced temperature of six degrees and a 26% reduction in energy that saves the convention center three million dollars a year.] The roof’s soil and plants absorb seven million gallons of storm water runoff. With statistics such as these, it is easy to see how a green roof can improve urban work, school, and home environments significantly. However, New York is not the only city reaping the benefits of green roofs. Major initiatives are happening in other U.S. cities such as Chicago, Portland OR and Washington D.C. Trending green roofs are also being built as urban produce gardens for tenants to manage. Some say rooftop farms are the definitive wave of the future. In fact, ecoroofs around the world sprout vegetable gardens and many of these rooftop gardens link to restaurants. Restauranteurs are choosing to utilize their roof space to grow fresh vegetables and herbs. These owners see the value in sharing fresh, homegrown produce with their customers. Rooftop agriculture is also producing crops such as grains and fruits along with vegetables. As building owners continue to see the value of installing a green roof, they are also deciding on which type of living roof will best suit their needs. The two specific types of vegetated roofs in common use today are intensive and extensive. Extensive green roofs usually contain one to six inches of soil, which means they can support only certain types of plants. These roofs are lighter in weight and have lower maintenance, nutrient, and irrigation requirements than intensive living roofs. Examples of plants used on an extensive roof, range from sedums to small grasses, herbs and flowering herbaceous plants which need little maintenance and no permanent irrigation system. Intensive green roofs, on the other hand, contain at least six inches of soil or more and will support a wide variety of plant types. Plant options can include full-grown trees and shrubs. These roofs are quite heavy and require a lot of maintenance. In the past few years, it is no longer a question of whether to go green. But more of a question of where and how to go green. Living roofs have been the answer to those questions. Green roofs provide a resolution for those seeking to turn a harsh urban environment into a sustainable, bucolic landscape. Living roofs improve a society’s quality of life. Their benefits are increasingly being identified, measured, and acknowledged by building owners and by the general public. Denver has just become the latest city to require rooftop gardens or solar panels on large, new buildings. Will this trend continue? Increased government support, new laws and incentive programs to install green roofs will help to ensure that the green roof trend in the U.S. will continue long into the future. Whether retrofitting a building with a contemporary green roof or starting from scratch, the load bearing capacity of a building must be determined first by a certified, structural engineer before plans for a green roof can begin.

They say that things are never too bad if you’ve got your best friend by your side. For a real estate investor, that person is often their engineer. There are numerous challenges for the real estate investor. One of the biggest is analyzing properties and getting a good return on investment. That’s why you should make an engineer your best friend. The sooner they get involved, the better decisions you can make. This can save you time, money and headaches.
How an engineer can help real estate investors save moneyA lot goes into deciding which properties are worth your investment dollars. An engineer may find those items that make an outwardly profitable property less so. Factors like how much it may take to develop the land, rehabbing an existing building and structural issues could cost major bucks that you weren’t planning to spend. Even the best looking properties can have hidden problems. Structural issues, drainage troubles and underground root growth are just a few of the issues that can eat up your investment and blow your budget. Having a qualified engineer walk through a property with you to point out potential problems can help you avoid making risky investment decisions. Finance is also a huge part of real estate investing and engineers are not afraid of math. As such, they might help you work through the numbers to manage costs, organize bids and make sure you are getting the best possible deal. To be successful as a real estate investor, you need to build a team of qualified professionals with the right expertise to help you. The field of engineering is multifaceted and broad and there are numerous specialties you will need along the way. While you may hire a home inspector to look at potential properties before purchase, a better option could be a mechanical engineer. Home inspectors are typically more like general practitioners, looking for signs of possible troubles. These professionals usually recommend consulting an expert, like a mechanical engineer, for further review. It’s the equivalent of going to your primary physician for a check-up and then being referred to a specialist for a more complete observation and comprehensive tests.
How an engineer can help real estate investors save money (cont)Also of note, engineers can work on the problems they locate; many home inspectors are prevented from doing this. Engineers are able to conduct a more exhaustive, thorough evaluation of a property. You can find structural engineers to answer questions about the safety and durability of a property. For example, they can help determine if the roof can support a large HVAC unit or whether it’s possible to tear down walls. Software engineers can design programs that help you reach more customers and streamline processes. They can also be used to help you find investment opportunities. Everyone knows that smart real estate investing can be like looking for a polar bear in a snowstorm; in other words, finding those hidden gems that can bring in a big ROI. Those with a software engineering background are in the habit of using networks and creating systems to filter through lots of information and find what you need. If your investment involves disturbing the land in any way, you need a civil engineer. Some states or areas actually require a report signed and delivered by a civil engineer for even a 50 square foot disturbance. Civil engineers who specialize in land development can help with zoning ordinances, property impediments and any soil problems. They stay up to date on local, state and federal land regulations to help you avoid surprises. In addition, civil engineers have experience in construction, managing contracts and completing construction projects. This kind of familiarity with contractors, project management and building codes can be invaluable in the course of real estate investing. It can help with cost estimation, land development, overcoming obstacles and time management. Also, having this kind of knowledge at your fingertips may put you in a better position for negotiating and property analysis. Unknown issues could be lurking just below the topsoil of a property. Sometimes environmental engineers might be needed for site assessments or regulatory compliance help. Electrical engineers can be beneficial if you want to make major electrical distribution changes or for troubleshooting and repairs. Real estate investors can also benefit from the services of a project engineer. This is someone you can use to communicate with design teams, obtain permits, prepare estimates and write contracts. It’s also possible to partner with an engineer that has experience in fixing old homes or solving home improvement challenges. Who better to advise you on purchasing a home or building than someone who has actually built one? With this kind of assistance, you could gain more freedom to take on those investments others may pass up, giving you an increased range and more profitability.
How an engineer can help a real estate investor avoid headachesEngineers often have a unique vision and way of thinking that helps them transform problems into opportunities. These mental tools and analysis skills translate well for the real estate industry. Engineering is about discovering how things work and finding solutions. Since real estate investing involves a multitude of problems, it’s helpful to have an engineer working alongside you so that when issues arise, you can rely on his keen eye for detail and problem-solving expertise. Purchasing a building or property is a painstaking and complicated process. You need someone with the patience and penchant for thoroughness that engineers have come to be known for. Engineers are also accustomed to being very project-focused and task-based. As a result, they know how to see a job through to its conclusion. The field of real estate investing can be tricky, uncertain and confusing. You need someone you can trust for sound advice to make the most of your investment dollars. Proper planning, financial management and the skills an engineer brings to the table are all vital for your success.
To find the right answers, you have to ask the right questions. When it comes to questions about homes and buildings, who better to ask than a structural engineer? Still, you need to know if the answers you get are correct. With that in mind, here are some of the most common questions every structural engineer hears and how the top-quality pros should respond.
1 – What, exactly, does a structural engineer do?Structural engineers specialize in determining the integrity of a home or building. They evaluate problems and establish solutions. A building or home must withstand numerous factors throughout its lifetime. Weather, gravity and the pressure that a structure affects upon itself can all lead to major consequences if it cannot endure against these forces. In the event that something goes wrong, you need to call a structural engineer. These are licensed professionals educated about the physics, materials and calculations that can affect how a structure will hold up under various conditions. They can determine the strength, durability and safety of a structure. This usually includes the building as well as related structures such as retaining walls, garages and new additions. If damage has been done and repairs are needed, a structural engineer will give you an objective breakdown of the issue and recommend the appropriate next steps. Most importantly, a structural engineer can help allay your fears. Often, homeowners are told they have structural damage that requires extensive repairs, especially older homes. These reports can come from contractors, inspectors or builders, telling homeowners the work will cost $10,000 or more. Many times, a structural engineer will conduct an impartial, third-party review and determine that while some repairs are necessary, it will be far less than the tens of thousands of dollars in the original estimate.
2 – There is a crack in my foundation. Should it be repaired?The foundation is undoubtedly the most vital part of any home or building. A structural engineer can look at the loads transferred and determine the root of the trouble. Load transfer could be the cause but sometimes, it may be a design issue. You might also be facing a drainage problem or too much root growth. He will determine the true cause and advise next steps.
3 – My building was reviewed by a home inspection company. Do I really need a structural engineer, too?A home inspector is typically a generalist who looks for signs of a potential problem. If they find something of note, they will usually advise you to consult a specialist to look at the issue in depth. A licensed structural engineer will know what to look for. In addition, he will have more knowledge and training on the problem than a home inspector would. Think of it this way: if you had a medical issue, a registered nurse could give you sound advice but for an expert opinion, you would ask a trained physician. Whether buying or selling, it’s crucial to hire your own structural engineering experts.
4 – What structural issues should I be concerned about when remodeling?In addition to the cost and time commitment of improvement projects, there may be many structural concerns. For example, before removing a wall, you need to know if it is load bearing. You might also want to correct sloped floors or bowed walls in basements. Prior to any significant retrofitting or remodeling project, it’s important to consult a structural engineer. They can make recommendations, conduct a review and keep your newly redesigned structure from falling down around you.
5 – What structural problems can be handled by a structural engineer?Soil movement (especially on a hill), damage from the weather or other natural causes, and destruction to load bearing wood by termites can be disastrous. There could also be issues regarding either interior or exterior stairs.
6 – How do I know you are qualified?Every state and the District of Columbia require structural engineers to be licensed in order to provide services. There are different fields, such as electrical engineers or chemical engineers, so be sure the professional you hire has the appropriate specialization. To obtain a license, they need at least a bachelor’s degree from an accredited institution. Additionally, some states require at least four years working in the field and passing the licensing exam. After receiving the license, structural engineers are assigned a special identification number. This number will appear on all approved plans and prepared reports. Beware of any structural engineer who will not or cannot provide his or her license number.
7 – What are some of the signs that I might need an inspection by a structural engineer?A cracked foundation or walls, sagging ceilings, windows that stick or won’t close completely and doors that jam or can’t be closed properly could all be signs of trouble. You might also notice leaning walls outside, a bulge or curve in a concrete wall or weakness and chipping in your concrete foundation. Other problems can include moisture in your basement or crawl space and cracks in ceramic or vinyl tile on your floors. Many of these troubles indicate a problem with the foundation. It’s best to fix smaller issues today before they become big headaches tomorrow.
8 – How can I know for sure that your work is high quality?You should ask for and expect a portfolio of recently completed work and references. Some good questions for references include whether the work was delivered in a timely manner and whether the project was explained in easy-to-understand terminology.
9 – What should I expect from an inspection by a structural engineer?All visible areas of the foundation are examined for signs of stress or deterioration Basement and crawl space is looked at for any evidence of moisture The framing should be inspected for signs of insect activity, rot and weakness Elements of the roof, such as flashing, surfacing and gutters are checked to ensure the best performance and no leaks
10 – How much does it cost to have an inspection done by a structural engineer?When buying or selling property, the costs can really add up. Many people don’t want to tack on the added expense of hiring a structural engineer to offer yet another opinion. On average, a structural engineer will charge $300-$500 an hour. Others may determine price based on a percentage of the total cost of a project. Although some companies offer free assessments, customers may still be worried that the engineer will over estimate the necessity of fixing a potential problem, leading to thousands of dollars in repairs. However, the price of any inspection is small change compared to repairing a major structural issue in the future.
So, you need an engineer for your next building project, but what type of engineer do you need? Well there are about 40 different types of engineering. The types of engineering range from mechanical to chemical to electrical, and many more. For your building project you’re going to focus on civil engineering. Civil engineering is an engineering discipline that deals with the design and development of infrastructure like buildings, roads, bridges, and railways. Civil engineers not only design and develop new infrastructure, but they also play an important role in rebuilding projects in instances like natural disaster. Civil engineers can be found in both the public and private sectors. This can be a very broad engineering discipline, so we will examine a few different branches of civil engineering. Site Engineering A site engineer’s role varies greatly from project to project. A residential project will have very different needs from a commercial or municipal project. Although their responsibilities change depending on the project, the basics remain the same. All projects will include organizational, technical, and supervisory tasks(examples?). Projects can be anywhere from a small home to a multi million dollar high rise. As part of the site management team, site engineers are responsible for the health, safety, organization, security, and supervising of people and resources. Site engineers are instrumental in effective communication with the site manager and subcontractors. They mark out the site, and they make sure the designs are implemented correctly. Site engineers also manage relationships with consultants, clients, and their representatives. Site engineers can be seen as managers of the construction site. They are a primary source of quality control and technical advice. Another essential job function is ensuring accuracy of all calculations, checking material quantities and drawings, and surveying the job site. Structural Engineering Structural engineering involves the analysis and design of structures that will safely bear or resist the loads, stresses and other forces. Structural engineer’s designs must satisfy given design criteria (as per the project guideline or code specified), predicated on safety, (e.g. structures must be load bearing so it does not collapsed while being used) or serviceability and performance (e.g. building must be stable and not sway causing discomfort to the occupants). Buildings need to be made to endure massive loads as well as changing climate and natural disasters. Structural Engineers have a responsibility to their clients and the community to provide safe designs. Typically, structural engineers are responsible for the structural design of the project, including the specification of the design loads, issuance of design documents, and review of submittals. Structural engineers are tasked with making creative and efficient use of the budget, structural design elements, and materials used to achieve these goals. Geotechnical Engineering Geotechnical Engineering deals with earth materials like rocks, underground water, and soil, and their relationship to the design, construction, and functionality of infrastructure. It is very closely related to engineering geology and is sometimes called ground engineering. Engineering geologists and geotechnical engineers work very closely. Together, they form a ground engineering team that is imperative to the investigation, design, and construction of infrastructure. Geotechnical engineering uses rock and soil mechanics to investigate the subsurface conditions and materials of a particular site. This means evaluating any displacements, stresses, and strains on the soil. This helps to determine the physical, mechanical, and chemical properties of the materials and assess any risks posed by the site conditions. All of this information is very important to the design, earthworks, and structural foundations of the project. The focus is analyzing and designing soil stabilization systems, which provide enough support to the structure that will be placed on the soil, ensuring the safety of the people using the structure. It is important that the structure is able to remain standing on unstable soil, and there are safety measures established to minimize the damage to infrastructure due to landslides or earthquake. Other projects a geotechnical engineer may take on deal with underwater soil, like offshore platforms and marinas. No matter what type of civil engineer you need, what matters most is that the engineer that you do choose is practical, efficient, and knowledgeable.

Structural engineers are people who focus on a specialized field of civil engineering. It involves the planning, analysis, design, construction, inspection, monitoring, maintenance, rehabilitation and demolition of permanent and temporary structures. Structural engineers handle the research of the behavior of structural systems and their components and reviewing the work of other engineers. It takes into account other factors such as the technical, economic, environmental, aesthetic and social aspects of structures. The various structures can include educational, municipal, multi-family, commercial, mixed use, institutional, religious, historic, coastal and residential. They can be composed of any structural material such as stone, wood, steel, concrete, plastics, aluminum, including composites and novel materials. Structural engineers are in a very creative profession and can be considered as an art as well as science. It makes a significant contribution to infrastructure and industry, as well as residential and recreational areas. The design of a structure simply means that the structure be built in such a way that it will be able to withstand all the load effects on it during its lifetime. The structure should not collapse due to any abnormal loading such as that occurring during an earthquake or landslide. Structural design is a balance of theoretical analysis and practicality, something that structural engineers typically excel at. It takes into account things like the degree of certainty of load bearing and forces, the actual behavior of the structure as opposed to the idealized design model, the actual behavior of the material compared to assumed behavior, and the actual properties of materials used compared to the assumed materials. Some structural engineers work to design the structures. Carrying out the strength calculations, while detailing and making structural drawings. Others specialize in the actual building and development of the structures, and some work in research. Structural engineers commonly work with other professionals such as architects, builders, mechanical, electrical and chemical engineers. This is to ensure that every aspect of the structure is safe, stable, economical, aesthetic, environment friendly, sustainable and capable of fulfilling their intended functions.
