    Most forensic investigation projects include a scope to determine the cause of some damage or condition. Project scopes often request determining the cause and origin of the damage. Since insurance policies contain descriptions of covered and non-covered situations, clearly specifying causes and origins is crucial for clients' coverage decisions. This article discusses the differences between and significance of these two important terms.

    Brick masonry chimneys have been prevalent for centuries, but it wasnt until recent decades that brick-clad, wood-framed chimneys became common in residential construction. This trend resulted from the increasing popularity of metal insert fireplaces. While they may appear similar from the exterior, the structure and weather-resistant envelope of wood-framed chimneys are very different than masonry-built chimneys. Prior to studying damage, it is important to understand critical elements in the structural support and weather-resistant envelope of wood-framed chimneys and the types of damage that can result from improper construction.[1]

    Fires can be caused by devices that fail due to a manufacturer's defect. Quality assurance procedures have gone a long way to eliminate out-of-box failures but manufacturers sometimes bypass quality checks on consumer products for competitive reasons. Even the most ethical companies are susceptible to human error that can cause an almost imperceptible change in an otherwise flawless manufacturing procedure.

    As the days get shorter and temperatures turn milder, most HVAC systems are taking a well-earned vacation. For a short while, a cool breeze through open windows will be enough to keep us comfortable in our homes. But soon, homeowners will switch their thermostats from cooling mode to heating mode, and some of them will unfortunately discover their HVAC system does not heat. It's time to pull out those extra blankets and make the call to a service professional sooner than expected.

    Wood bowstring trusses were used extensively in commercial buildings from the 1920s to the 1960s. Wood bowstring roof trusses provided long clear spans necessary in warehouse and industrial buildings. Many roofs supported by bowstring trusses are still in service today. Compared with other structural timber-truss types, bowstring trusses have exhibited more frequent structural problems. The structural deficiencies encountered are attributable to deficiencies in the original design of the trusses combined with damage due to exposure and age.

    The National Fire Protection Association (NFPA) has released a 2015 edition of NFPA 70E: Standard for Electrical Safety in the Workplace. It covers and assists in complying with the Occupational Safety and Health Association's requirements, including changes to requirements since the last edition. For personal safety in forensic studies it is important to stay informed of these updates. NFPA 70E covers arc flash risk assessment, establishment of arc flash boundaries, requirements of Personal Protective Equipment (PPE), use of PPE within the arc flash boundary, and equipment labeling requirements regarding arc flash hazards. The following examples illustrate the importance of staying abreast of the latest standards.

    History shows us that building codes have been around for a long time - in fact, the earliest known was around in 2000BC[1]. Penalties were also much harsher for construction defects. If a builder constructed a house that collapsed and killed the owner, the builder was not fined, but was put to death. The United States has been a country with diverse codes - as many as 5,000 at one time. More recently, however, various states and municipalities have adopted "model" codes such as the International Building Code or International Residential Code. These provide a "base" and may be used as written or an Authority Having Jurisdiction (AHJ) may amend certain parts of the model code, making it more stringent and/or specific for a certain area.

    Whether it is helping us formulate our opinion or confirming an initial diagnosis, technology plays a valuable role in forensic engineering work. Following are a few examples of existing technology available to Donan's project managers. Though not standard issue, these tools are utilized when necessary to accurately determine or confirm a cause of loss.

    There are many types, manufacturers, and sizes of commercial HVAC systems which can make it difficult to create general guidelines for repair procedures and estimates for hail-damaged units. This guide uses the most common "light commercial" rooftop units (RTUs), which are 5-tons, 7.5-tons, and 10-tons in capacity, for estimating time to repair or replace.

    Imagine for a moment that you are sitting in your home, listening to the rain while reading your favorite novel. Then suddenly you hear a roar of thunder and your home becomes dark. What just happened? You may have just experienced a power surge. Although lightning is not the most common cause of this phenomenon, it is excellent for illustrating what a power surge is and how it can affect your home. A power surge is a term used to describe a condition where the voltage and or current increases beyond its normal levels. Power surges, when due to the elevation of the voltage being supplied by the electrical utility company, have the potential to change data streams, interrupt electrical control circuits, burn out components, cause arcs, create shorts between conductors, overload systems, and cause system failures. The most common causes of power surges are indicated as follows:

    Concrete is a desirable construction material due to its inherent strength and durability, which make it well-suited for many applications in residential and commercial construction, especially foundations, floor slabs, driveways, sidewalks, and roads, among other things. In these applications, concrete that is properly designed, mixed, placed, and maintained will perform exceptionally well for many years. However, poor design or mix, improper placement, finishing techniques, or inadequate maintenance may result in concrete that does not perform as intended. Aside from cracking, which is probably the most common form of distress to concrete, since virtually all concrete will crack as it cures, surface distress due to scaling, spalling, and popouts are the most common forms of damage.

    The relationship between wind, hailstone velocity, and impact energy is based on an understanding of fundamental physics. Over a half century of laboratory research and field studies have determined that the severity of hail damage to a roofing material is contingent on the kinetic energy at the point of impact and the roofing material's resistance to that impact energy. These studies have found that a hailstone must be of a certain mass (i.e., size), and it must be traveling at a certain speed (velocity) to result in functional damage to the roofing material. The kinetic energy is a composition of mass and velocity, defined by the following equation:

    Chances are, it's happened to you. An unexpected period of cold weather occurs and temperatures drop well below freezing for an extended period of time. One morning you attempt to turn the water on in the kitchen sink and...nothing. Hot water? Nope. Cold water? Nope. What happened? Did you forget to pay the water bill...again? Chances are, your pipes are frozen. "How can that happen? They are inside the house!", you may say; however, just because your water lines are inside the building envelope, does not mean they are adequately protected from freezing.

    If hail impacts a roof covering and the effects of this impact result in some loss in the material's overall integrity or functionality, this material is classified as "hail damaged." More specifically for cedar shakes and shingles, valid hail damage is typically a new fracture of the cedar corresponding to a clean spot or scuff mark from the hailstone impact.

    Although sags along roof ridgelines can be discovered at any time, in northern climates they are often attributed to the effects of a past snow load. To make an educated analysis of the actual cause of this phenomenon, one must have a basic understanding of the structure and the loads to which it has been subjected.

    Heating, ventilating, and air conditioning (HVAC) systems consist of many components that work in unison to create the desired comfort level for our homes and offices. A well maintained system is designed to last around 15 years, but the life can be dramatically reduced when proper installation procedures and routine maintenance are not performed.

    Washing machine failures can create significant damage, exposing insurers and their clients to property damage. These failures often involve a high volume of water and can occur without warning. Through the examination of several hundred washing machines, the DONAN Component Testing Laboratory has identified a statistically significant failure trend in General Electric (GE) washing machines. The amount of water supplied to the tub of the washing machine is controlled by a water valve (solenoid-controlled valve) and pneumatic controls. The washing machine's load selector is a pneumatic pressure switch, which activates and deactivates the water valve.

    Shallow foundations are the most commonly designed and constructed structural foundation system. As opposed to deep foundations where structural loads are transferred to subsurface layers or multiple depth ranges, shallow foundations transfer loads to the earth (soil) relatively near to the ground surface. Some examples of shallow foundations include building components often seen in residential construction such as spread footings, continuous foundation walls and footings, slab-on-grade foundations, and mat-slab foundations.

    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.

    For many years, the fire investigation industry has seen numerous fires involving livestock buildings. These fires are often high profile, especially when masses of animals are lost or injured. Many times these losses are in older structures with neglected electrical and/or heating systems. Given the interior environment, corrosion and degradation to electrical and heating components are common.

    While shovels, snowblowers, plows, and deicing agents are used to clear snow and ice from driveways and sidewalks during the winter, removing frozen precipitation from the roof of a house is a bit more challenging. As snow and ice piles up on the roof and subsequently thaws out, the melt-water can sometimes result in damage to the interior of the structure.

    The role of an accident reconstructionist is to provide a forensic conclusion to the cause and events of an accident. Some accidents may involve passenger vehicles or consumer products, such as an ATV.

    Many highway traffic accidents occur as a result of sudden tire failures. One particular kind of tire failure is called tread separation, and it can be especially dangerous in some circumstances. This kind of failure involves the outer steel belt layer of the tire peeling away violently, often without causing the tire to go flat.
