Understanding the structural load path is imperative when considering renovations in a home that may require the removal of a load-bearing wall. Some homeowners consider adding a new door or window opening and worry if the structure will collapse. Another reason could be that the owner wants an open concept floor plan. The goal is to remove walls and open their living space. Read More
Hail property damage is frequently reported after an HVAC service call. Building owners are often unaware there is damage until the power bill starts trending higher and the HVAC system is simply not cooling effectively. Take look at the fins! The National Weather Service reported over $722 million in property damage from hail in 2018. Based on NWS data, hail caused more property damage than tornadoes or thunderstorms. Only Tropical Storms/Hurricanes at $12 billion, coastal storms at $1 billion and flooding at $1 billion were more costly than hail to property.
One of the items very susceptible to damage is the HVAC system. The heat that is removed from the interior of a building must be rejected to the environment. As such the HVAC system is placed where it can have unhindered access to outdoor air in order to function properly. This often results in the unit being placed in a large open space such as a rooftop, making it susceptible to damage such as hail. Read More
A wall is really boring until it fails. A retaining wall is supposed to hold back soil to either support a structure or keep a space clear. When it fails, both of those roles are compromised. A retaining wall does not have to collapse to fail. In fact, a failure is perhaps better defined as when the wall does not perform as expected. Read More
Fire. Something about fire touches our brainstems…both good and bad! Uncontrolled fire is terrifying and deadly to be sure. But the controlled burning of wood at a campfire or in a fireplace in your home almost can’t be beat, to my mind! For that very reason, a fairly common amenity to houses nowadays is the gas log fireplace insert.
When not installed properly, these logs will generate soot. These soot particles can leave the fireplace and meander. All. Over. Your. House. Read More
The Occupational Health and Safety Administration (OSHA) “Top 10 for 2018” violations once again have Machine Safeguarding earning a position on the list. Machine safeguarding was the 9th most cited standard as noted in the list below:

While on a lunch stop during a recent vacation trip through Tennessee, I happened across a safety hazard that required immediate attention. The establishment had a raised concrete patio at the front with a steel railing around the perimeter. At one edge of the patio was a set of stairs with a continuation of the steel railing used as a handrail. The top edge of the patio had light strings wrapping the top metal bar as accent lighting for the perimeter. The light string continued down the stair handrail wrapped in the same manner as the rest of the patio. Read More
A mini-excavator at a job site developed a leak at a hydraulic fitting at the base of the cylinder that raises and lowers the boom. A subcontractor foreman at the site raised the boom to search for the leak. The foreman found and attempted to tighten the leaking fitting. When he did, the fitting separated from the base of the cylinder, releasing the hydraulic pressure that held the boom aloft. The boom fell and the bucket struck a nearby superintendent for the general contractor.
Equipment and appliances supplied with fuel gases like natural gas, propane and butane are a common and convenient part of most of our lives. Such devices as gas grills and ranges, ovens, furnaces, space heaters and water heaters usually perform without incident. However, when they malfunction the potential for incidents such as fires and explosions, carbon monoxide (CO) poisoning and burn injuries may occur. These incidents may be due to design and manufacturing defects in the product, or improper installation or operation of the device.
Several dangers involving the use of a hot tub (spa) may readily come to mind, such as the risk of shock or electrocution, or the risk of drowning for unsupervised young children. Not so readily apparent is the effect of overheating the human body, or “hyperthermia”.
Some individuals are more susceptible to the effects of hyperthermia, including the elderly, young children, and those in poor health. The effects of hyperthermia, or overheating of the human body, cause direct responses such as headache, nausea, heat exhaustion, increased cardiac output, lethargy, confusion, heat stroke and unconsciousness. The onset of hyperthermia is defined as being at 99.5° F; if the body temperature reaches 104° F, a life-threatening medical emergency exists. Read More
Many people just take for granted that something is just going to work, and in many cases assume that it will work forever. One such device that does not get enough attention is the Ground Fault Circuit Interrupter (GFCI). Simply put, a GFCI is a protective device that compares the current flowing on the hot and neutral wires of the circuit and will “trip” to disconnect power to the circuit if a small imbalance of current is detected. The imbalance of current is an indication of a dangerous alternate path for the current to flow from a damaged line cord or a fault inside an appliance and constitutes a shock hazard to a person.
