Have you ever seen that yellow sign before driving over a bridge that says, “Bridge Ices Before Road” and wondered why? A major reason is that cold air surrounds the bridge from above and below, which means that heat within the bridge deck is lost from all sides. Roadways, however, are protected by the ground below which helps trap in heat.
Another reason is that bridges are often constructed with concrete and roads are typically paved with asphalt. Asphalt pavement is much less dense than concrete which means that the asphalt absorbs heat much better than concrete because the heat can penetrate deeper into the pavement. Additionally, asphalt pavement will retain the heat better than concrete and lose trapped heat more slowly than concrete as the ambient temperatures fall.
Landscape Infiltration devices have become a favored method of controlling and filtering sediment and pollution carried by rainwater runoff, replacing large sediment ponds previously used. Landscape infiltration devices utilize beds of sand, gravel and mulch, along with native plantings to filter the runoff before the water enters the stormwater system. When completed, the area appears to be a nicely landscaped section of the property.
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.
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.
The ETC team will be attending the Washington Metro Chapter of CAI Conference & Expo on Saturday March 10th. We would be so pleased if you stopped by to say hello.

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.
Incomplete combustion of wood in fireplaces creates a buildup of flammable oils (creosote) in chimney flues, which can contribute to chimney or building fires. Only dry, seasoned wood (preferably hardwood) should be burned in fireplaces. Green and/or water saturated wood burns at a lower temperature and less completely than dry, seasoned wood and poses a greater potential for creosote deposition. Coniferous woods (pine, fir, spruce, etc.) should not be used. They tend to be highly resinous and will deposit more material than hardwoods. Household trash or other items should never be burned in fireplaces.
Artificial logs should only be used in accordance with manufacturers’ instructions and limitations. Most such products are intended to be burned only one at a time. Artificial logs vary in composition from hardwood fibers (sawdust or other sawmill waste) combined with wax or other binders, to petroleum wax (paraffin) mixed with various recycled materials. As a general rule, artificial logs should not be used unless the composition and burning characteristics of a specific product are fully described and deemed acceptable. Plastics, unidentified composites, or other materials of questionable makeup should be avoided.
Fireboxes require occasional cleaning/removal of ashes. Ashes should only be removed when absolutely no embers are present. Because embers can remain undetected long after a fire is out, ashes should only be placed into fireproof, metal containers.
Chimneys should be periodically inspected and cleaned, the frequency of which depends on fireplace use. Annual inspection is recommended for fireplaces that are used regularly. Cleaning may not be necessary at every inspection interval. It should be noted that chemical cleaners (cleaning logs, fire additives, etc.) should not be considered equal to professional cleaning.
Some products incorporate catalytic chemicals that react with the creosote and cause it to soften, flake and debond; however, the dislodged material can accumulate on shelves or other chimney offsets. They also tend to react only with the outer layer of creosote and are only partly effective in the presence of heavy buildups. They also may have no appreciable effect on soot, or residue from artificial logs.
Some products (which employ copper or other metal salts) rely on the rapid expansion of gas created when the salts are burned to dislodge deposited material. The effectiveness of those products is questionable, particularly with respect to heavy accumulations.
Before any rope descent system (i.e., window washing boatswain chair) is used on a building, OSHA now requires that each anchor be identified, tested, certified, and maintained so it is capable of supporting at least 5,000 pounds in any direction.
Did all your anchors pass the test?
The OSHA set November 20, 2017 deadline for physical load testing of these anchors has passed. (29 CFR 1910.27(b)(1)(iii)).
Did you make the deadline?
We loaded anchors of many different configurations and found that not all anchors passed this stringent test. If you have any anchors that have not been subjected to this testing in the last 10 years, they must be load tested and certified by a qualified person before they are used. This regulation also seems to apply to new anchors that were installed after the November 20 deadline and not just older anchors.
Don’t postpone your scheduled winter or spring window washing work, get your anchors tested soon. Call us @ 410-312-4761 or 703-450-622o | email@example.com
