Always nice to collaborate with others in the industry. Outstanding work by ETC’s Chief Structural Engineer, Chris Carlson, PE and Project Engineer, Luke Valentine, PE. Job well done!
ETC is pleased to announce a forthcoming change in ownership.
Since its inception, nearly 4 decades ago, Joe Shuffleton has been owner and president. Through his leadership, ETC has grown to be a highly-reputable engineering and architectural firm specializing in the restoration and rehabilitation of existing commercial structures in the Washington-Baltimore metropolitan area. Mr. Shuffleton successfully guided the growth of his team that now spans three, multi-state offices.
Five individuals comprise the new ownership group. Mr. Shuffleton has, without reservation, come to trust and depend upon these induvial for many years.
- Chris Carlson: With over 30 years’ experience, the last 12 as our chief engineer, he is the key technical person behind our entire structural team.
- Mindy Maronic: With over 20 years of marketing & client relations experience, she has brought our company to the forefront of business excellence.
- Kirk Parsons: Our vice president of operations for over 20 years, he has played a vital role in building company growth and client loyalty
- Bobby Radcliff: The newest member of the group, with 10 years at ETC, he is also a talented, lead engineer with strong business acumen.
- Jeff Shuffleton: Our technology and administrative director, he has assured clients accurate and efficient company procedures for the past 15 years.
Commenting on the transfer of ownership, Mr. Shuffleton states “As I prepare to step away, simply to enjoy the next juncture in life, I am fortunate to turn to my key employees who have played a pivotal role in the growth of ETC. It is these employees who will take over where I leave off; growing the company on the same guiding principles and business ethics upon which ETC was founded. I am proud of all that we have accomplished, and equally proud in the legacy and exciting opportunity I pass on to them and the entire ETC team”.
Under the new leadership, the plan is to keep the company’s direction true to Mr. Shuffleton’s vision:
ETC has no desire to be the biggest firm; however, we do strive to be known as the best. To that end, the needs of each assignment are analyzed and matched to the capabilities of our high caliber technical staff. We will not take on any project if we do not have the competence required or if for any other reason we are unable to meet client expectations.
Joe Shuffleton will stay on for a period of time to gently guide the company through the transition. He will also serve as both a consultant & ambassador, watching ETC as it thrives under its new leadership.
Your AC unit has many parts functioning together to enable the generation and distribution of cooled air. The most essential part is the compressor, which is responsible for pumping and circulating liquid refrigerant through the AC system, generating cooled air. By paying attention to these 5 signs, you can diagnose if your compressor is malfunctioning.
Moisture around outdoor unit
If moisture or puddle is found on any section around the outdoor unit, this could be a sign that the compressor is leaking refrigerant. A refrigerant leak can pose serious safety issue that can contaminate the airflow and cause occupants to experience headaches, coughing, irritated eyes, nausea and more. Eventually, the unit will fail as the refrigerant needed to generate cool air is depleted.
Does your outdoor unit generate louder noise than usual? Do you hear any ticking or chattery noises when the unit is turned on? These symptoms could give a clear indication that the compressor motor has become loose and is rattling around inside the unit, or the electrical components are wearing out and need replacement.
Excessive vibration of outdoor unit
If your outdoor unit is shaking violently the moment it turns on, it is very likely that the compressor motor is malfunctioning and need a new replacement.
Circuit breaker tripping
Does your AC outdoor unit keep losing power and tripping the circuit breaker? This is a sign that your compressor is overloading by drawing too much power and thus becomes overheated. Therefore, a professional inspection should be performed to accurately remediate the problem.
Higher than normal temperature
Is warm air coming out of your vents while the AC is on? A failing compressor can struggle to pump refrigerant and keep it circulating throughout the system, causing inadequate cooling power.
If you have a building that needs HVAC evaluation, or are just curious to know if your system is functioning properly, ETC has the first-hand experience to provide professional inspection and consultation regarding technical problems, as well as methods to correct them.
Have you considered coating performance options?
If you have decided to replace your deteriorated railings and/or windows with new, low-maintenance aluminum products, you may think selecting the coating color is the most difficult decision remaining. However, have you considered the coating performance of your new railings and windows?
Typically, coatings for these items fall under three (3) levels of performance as defined by the American Architectural Manufacturer’s Association (AAMA): Good Coating Performance (AAMA 2603), High Coating Performance (AAMA 2604) and Superior Coating Performance (AAMA 2605). Coating performance can be based on several factors, including coating thickness, color retention, gloss retention, coating erosion, chalk rating, humidity resistance and salt-spray corrosion resistance.
Specifying the coating performance largely depends on location, cost and exposure to the environment. Although having the superior-rated coating will provide the best long-term performance, it will be substantially more expensive, especially with a large railing and/or window replacement project. Unless the coatings are subjected to harsh environments (such as sunny coastal regions), the lower-grade coatings may meet your project needs.
To determine what coating performance option may be best suited for your project, members of our Architectural and Engineering staff are available to assist you. Developing architectural renderings with color and coating options are invaluable before undertaking such an important project.
Since 2015, ETC and its employees have teamed up to support those with disabilities through canine assistance. With planning and participation from our dedicated staff, we have been able to raise thousands of dollars for non-profit working dog organizations, such as Canine Companions for Independence.
ETC has recently expanded its canine out-reach efforts with our very own company dog, Blue (our corporate color). Blue is a certified therapy dog who will be visiting local hospitals, senior centers, schools and library reading programs.
Together we hope to enhance the communities in which we live and do business.
It is too early to tell what might have failed and caused this bridge to collapse and it will probably be many months before the investigation is complete. The bridge was designed to consist of post-tensioned concrete segments supported by steel cables. It was to have been built in two sections and only the first section was in place when the collapse occurred. The first section of the bridge had only been in place for five days before it fell, so it is not likely a case of being grossly under-designed or inadequate concrete strength. One report indicated that the post-tension tendons had loosened and were being retightened when it fell.
Institutional and government projects like this have many levels of design review and material testing involved to help ensure public safety and that the 100-year design life is achieved. This bridge was far from complete as there was a central support pier (pylon) for the steel cables that still needed to be installed. This pier and the cables would have provided additional support to the failed section of the bridge. Partially constructed structures can be very dangerous.
This catastrophic failure reminds us of the inherent hazards of all construction work, not just those involved with demolishing and rehabilitating portions of existing structures. Our prayers go out to all those involved in this tragedy.
When evaluating asphalt pavement, including asphalt-paved parking decks, ETC recommends core sampling as part of our investigative service. Extracting a core sample of the pavement can be beneficial in telling the history of the pavement construction as well as the conditions of the sub-base profile beneath the asphalt.
The cores can also tell the story of past pavement work, including structural repairs, pavement membrane (fabric) installation, and multiple repaved layers of asphalt, which can help minimize change orders during the work. This information assists us in developing specifications necessary to address the pavement rehabilitation needs.
Typically, pavement deterioration can be traced back to the sub-base design (the materials below the pavement) and their manner of installation and compaction. What we commonly look for is a stone aggregate material in thicknesses that exceed the pavement profile. In many instances, our sampling will also reveal the condition of the sub-base (or soils) below the pavement as well. Soils with high clay content can affect our recommendations for the type of rehabilitation work.
If these conditions are not defined before scope preparation and implementation, the pavement rehabilitation work may not adequately address the needed issues. This can lead to a reduced pavement life and more costly, long term repairs.
Don’t hesitate to contact us for all your pavement questions and concerns. We can have a member of our pavement consulting and inspection staff visit your property to provide a pavement evaluation proposal, free of charge.

Unfortunately, there isn’t a quick fix for addressing footprints in your sidewalk. Your best bet is to remove and repour the affected panel (section between control joints). There are other options out there including filling the footprint in with a repair material (e.g. sand filled epoxy), patching the area, or grinding down the area, but these repairs will be noticeable and/or may require follow-up repairs down the road.
An all too common building problem involves the formation of condensation (water) on the interior surfaces of windows. This can be caused by a variety of factors including deficiencies with the windows, the use of heavy window treatments that prevent air circulation on window surfaces, and excess moisture in building interiors. Sometimes, when too much condensation is present, water may even drip down the wall into the wall cavity or onto the floor to cause water damage, growth of mold and mildew, staining, and other problems.
Normal human activities (such as respiration, bathing, laundering, cleaning, cooking, pets, houseplants, aquariums, etc.) produce water vapor that must be accounted for in the design of the mechanical (heating, ventilation, and air conditioning or HVAC) systems for the building. In today’s air-tight buildings, window condensation can result from insufficient fresh air. Unless fresh air is introduced into conditioned space, humidity can accumulate until, in cold weather, the temperature of the interior window surfaces becomes so low that the air at the surfaces become saturated, causing water, or even ice, to form.
Why does fresh air help to reduce humidity? In a cold weather scenario, the outside air is dry and by introducing sufficient fresh air (increased ventilation) into the building, the humidity is diluted and reduced. However, too much fresh air may not always be a good thing during the heating season. In addition to high energy cost, too much fresh air may also render the space too dry for a comfortable environment.
Sometimes the issue may not be as simple as it looks. Improperly designed or installed HVAC systems can fail to remove the moisture and cause elevated indoor humidity. Undersized systems could produce inadequate air movement to remove water vapor. Oversized systems could prematurely satisfy heating and cooling demands, resulting in short-cycling, and reduced air movement. It is important to conduct a thorough investigation to identify the real cause of condensation issues in order to develop a successful and cost-effective solution.
ETC has first-hand experience with these problems and the methods to successfully correct them. Our mechanical engineering staff has the ability to identify and correct ventilation issues involving condensation or other concerns
Imagine a winter without the need for ice melt. Researchers at Drexel, Purdue and Oregon State University are working with concrete admixtures to hopefully make this a reality. Their research includes the addition of phase changing materials such as paraffin, coconut, or palm oils into the concrete mix and has proven to melt snow in certain conditions. The phase change materials release thermal energy as they solidify, meaning as the temperature drops, they release heat, which melts the snow. The inclusion of the phase changing materials in the concrete mix result in a one-time cost at construction rather than reoccurring costs, such as electricity, in cases where heating elements are embedded in concrete for snow melting. More information on the research can be found at the following link: http://drexel.edu/now/archive/2017/September/self-melting-concrete-roads/.
The Researchers state that this technology is ideal for the Mid-Atlantic region as the performance of the phase changing materials works best where the temperature frequently moves above and below freezing. There are many benefits to eliminating the use of deicing chemicals. Reduced operating costs and the reduced deterioration of concrete structures are the most beneficial to Building Owners. While to the environment, eliminating the use of traditional deicers will help keep the millions of tons of salt used in the region during a typical winter from entering the local waterways.
The new mix additives are expected to begin large scale testing in early 2018. While probably a few years away from widespread commercial implementation, it is nice to think that one day we may never need to clear our sidewalk of snow.
