Case Synopsis - A family wanted to add a self-contained heater for their home living room for use upon the loss of in-home AC (Alternating Current) power. They went to a nearby Home & Building Supply store to select and purchase a heater. The store salesman recommended a kerosene heater, which could provide independent heat upon a loss of power. The salesman recommended a kerosene heater rated at 23,000 BTU/Hour, and as a feature of the heater sale, he assembled the heater and provided brief operating instructions on its use.
When I was a boy, playing in the sandbox or building with blocks, I dreamed of building cities. I feel fortunate to be in a profession which allows me to fulfill that dream. To enjoy your job is a more important measure of success than the amount of money in your bank account. My favorite definition of success is borrowed from Ann Landers:
The nursery rhyme involving Humpty Dumpty is a child's first lesson in safety. What would keep Humpty Dumpty safe as he is sitting on the wall? A warning or a railing?
Too frequently an attorney will begin to seek a potential expert witness only after having done considerable initial work. Often there is a last minute rush to locate and select specialized technical assistance. These approaches can have expensive consequences. Alternatively, securing a suitable expert early in the litigation process offers the following advantages for the retaining attorney:
Many negative consequences can result from failures of a range of different products that often lead to property & casualty insurance disputes or product liability legal actions. The products may include consumer or industrial goods. Typically the private user or worker is injured or a business incurs significant financial loss. The injured individual, insurance carrier, attorney(s) or industrial manufacturer and user are all interested to confirm what went wrong – and who is liable. Resolution often depends on engineering analysis.
The Health Center building on the Milton Hershey School campus was designed in 1932 as load-bearing masonry construction with steel framing used to support floor and roof loads and loose steel lintels spanning over window and door openings. Atkinson-Noland & Associates was retained to conduct an investigation of the exterior load-bearing masonry walls and structural steel framing for the purpose of identifying typical as-built conditions as well as the locations and severity of any deterioration.
Cooling for indoor Grow Ops involves more than simply adding up the lighting watts and converting that into cooling tons. Plants release a surprising amount of moisture into the air (by transpiration, plus evaporation from the soil), and this has to be accommodated as latent load in the air conditioning equipment. The result when using standard air conditioning equipment for dehumidification will often be over-cooling or insufficient dehumidification. Adding in-room dehumidifiers can help, however they normally reject the heat from the process back into the room, which the air conditioning equipment needs to remove.
I expect that in the future architects, owners, engineers, and occupants will work together to “engineer” buildings as active, “living” systems that put more energy back into the grid than they use and also help to clean the air and water in the nearby communities.
A licensed professional engineer (P.E.) is required to adhere to a Code of Ethics for Engineers in all work he undertakes. However, there are some special criteria when employed as an expert witness.
In urban and suburban areas, stormwater systems are found everywhere. From surface waterways, such as rivers, streams, and ditches, to subsurface drainage systems, such as storm sewers and culverts, stormwater systems are as ubiquitous as concrete, which is one of the reasons they are so important (Figure 1). Impervious surfaces like concrete, pavement, and roofs prevent stormwater from naturally absorbing into the ground, and the resulting runoff can cause flooding, erosion, and subsequent structural damage.
